Contents of the invention

The present invention proposes a kind of comfortable and skin-care multifunctional braided fancy yarn and its preparation method. A strongly twisted yarn is used as decorative yarn. The kink of the resilience produces irregular small braids, which are attached to the middle of the core yarn and the consolidation yarn to become a braided yarn. It is mainly used for yarn-dyed women's wool, knitted sweaters, tweeds, sweaters, overcoats and hand-knitted wool, etc. The knitted fabric made of hollow braid fancy multifunctional antiviral health care yarn is comfortable to wear and is an ideal fabric for processing high-end products.

The technical scheme for realizing the present invention is: a comfortable and skin-care multifunctional braided fancy yarn, the braided fancy yarn is made of fixed yarn, decorative yarn and core yarn, the decorative yarn is fed by an overfeeding method, and the decorative yarn The kinks are braided and attached between the core yarn and the fixed yarn to form a braided fancy yarn.

The braid fancy yarn of the present invention comprises three kinds, and the first is hollow braid fancy yarn, the second is elastic braid fancy yarn, and the third is porous braid fancy yarn.

Preparation of the first hollow braid yarn:

The core yarn of the hollow braid fancy yarn is a core-spun yarn processed from bamboo charcoal fiber, isatis root fiber, copper fiber, chitin fiber, and water-soluble vinylon filament; the fixed yarn is a blend made of negative ion polypropylene fiber and bright polyester fiber Yarn; decorative yarn is a strong twisted yarn blended with rabbit hair fiber and hemp fiber.

The first step is to spin the core yarn of the fancy yarn. The process flow of the system is as follows: opening and cleaning→carding→drawing (three passes)→roving→spinning→post-processing.

The equipment process for spinning bamboo copper chitin antiviral hollow yarn (water-soluble vinylon fiber filament) is as follows:

Bamboo charcoal fiber, Radix isatidis anti-virus health fiber, copper fiber, chitin fiber → automatic weighing and mixing → FA042 automatic weighing machine → FA017 automatic cotton mixing machine → FA106A comb roller opener → FA161 vibration feeding Machine → FA142 type single-hand lapping machine to make rolls → FA231 carding machine → FA302 drawing frame (three lanes) → TJFA458A roving frame → EJM128K spinning frame → GA015 winding machine → baling .

In the cotton opening and cleaning step, the disc automatic catching machine is not used, the number of hitting points is reduced, and the distance between the beater and the cotton feeding roller of the cotton opening and cleaning machine is appropriately increased, and the distance between the beater and the dust bar should be appropriately large Control; the proportion of ingredients should be adapted to the reasonable arrangement of cotton bales. Cotton bales are arranged so that the same raw materials are dispersed vertically and split horizontally. When the cotton bales are uneven, it is necessary to "cut high and caulk, low bales are loose and high, and the large area depends on the level". Mixed flowers should be clamped by cotton bales, and it is best to use them after baling. According to the principle of "grasping frequently and grasping less", the effect of opening and loosening is good and the operation efficiency is high. Usually a short process is used. The cotton box has the function of promoting mixing and improving the uniformity of the cotton lap. During the production process, the principle of "more loosening and less beating, splitting instead of beating, no falling and less falling, fully opening and mixing" should be followed. The beater form should adopt the combing needle type, and the cotton cleaning machine should use combing needles or integrated beaters, in order to beat lightly and comb more. Generally, the speed of the comb roller is 500-600r/min; the speed of the three-wing card beater is 750-900r/min; the speed of the fan is generally 1200-1400r/min, and the speed of the lap roller is 10.3-12.5 rpm.

The carding machine adopts metal card clothing, which can prevent the fibers from sinking, reduce stuffing, and obtain better carding quality. Therefore, the selection of the card clothing not only needs to consider the good carding effect of the fibers, but also pays attention to the smooth transfer of the fibers from one needle surface to another. For processing polyester fibers, choose a licker-in saw blade with a small working angle and large tooth density. Correct selection of cylinder and doffer card clothing specifications is the key problem in carding and transfer. The licker-in speed must match the cylinder speed. A high licker-in speed is good for opening and removing impurities, but too high will cause fiber damage. Generally, the cylinder speed is 280-340r/min, and the licker-in speed is 600-860r/min. The cover plate speed affects the impurity removal efficiency and the cover plate flower amount. Since the chemical fiber has less impurities and short fibers are easy to be discharged in the cover plate flower, the cover plate speed can be controlled at an appropriate low level, generally controlled at 78-140mm/min; Doffer The speed is controlled at a low level, which is beneficial to improve the quality of the cotton net, generally 22-30r/min. In the drawing process, the gauge of the three drawing rollers is 15×24mm, and the pressure of the three drawing rollers is 30×32×30kg; in the roving process, the spindle speed is 550-700r/min, and the front roller speed is 160 -225 r/min.

When spinning in the spinning process, the EJM128K spinning frame is used, and the ring spinning frame is modified, and a set of water-soluble vinylon filament positive feeding device is installed to produce core-spun yarn, which is then spun into Bamboo copper chitin antiviral hollow yarn (water-soluble vinylon filament).

In the winding process, the GA015 winding machine is used. Due to the prominent electrostatic phenomenon and the large amount of winding hairiness, the winding speed is 300-500m/min, and the winding speed and tension are relatively small. Temperature and humidity, to ensure smooth winding channel, reduce winding hairiness, and maintain the elasticity and physical and mechanical properties of the yarn to the greatest extent.

The second step is to select fixed yarn and decorative yarn. In the multi-functional anti-virus health care hollow braid fancy yarn products: fixed yarn→negative ion polypropylene fiber and bright polyester fiber blended yarn; decorative yarn→rabbit hair fiber, hemp Fiber blended strong twist yarn.

(1) When processing fixed yarn → negative ion polypropylene fiber and bright polyester fiber blended yarn, the process flow similar to the first step above is adopted.

After the raw material package enters the workshop, the packaging wire should be removed in time, and it should be placed for at least 24 hours to balance the temperature and humidity between the raw material package and the workshop. In order to improve the spinnability of the fiber, it is also necessary to spray an appropriate amount of water and antistatic agent on the fine denier polyester fiber to ensure good quality of the yarn.

The principle of the process design of the opening and cleaning process is "short process, low speed, full mixing, gradual opening, less tumbling, more carding, more loosening and less beating, thin feeding, full mixing, low speed, thin feeding".

The principle of carding process design is "strong carding, light weight, low speed, small pressure, tight gauge, strong carding, clean and smooth channel, anti-blocking, large speed ratio, appropriate gauge, five fronts and one Standard" process principle.

The principle of drawing frame process design is "proper gauge, stable grip, strong control, uniform draft, smooth draft, multiple mergers, heavy pressure, light weight, large gauge, low speed, and anti-winding" .

The principle of roving process design is "light weight, large gauge, heavy pressure, large twist, small tension, medium axial and radial winding density, small elongation, small rear draft, small jaw, moderate collector caliber".

The principle of the spinning process design is "large gauge, medium twist, heavy pressure, medium-hard rubber roller, medium speed, small rear area draft, small jaw, reasonable workshop temperature and humidity, and the use of new spinning equipment ".

The principle of the process design of the winding process is: "light tension, small elongation, elastic retention, wear reduction, small speed, and hairiness reduction" are adopted in production.

(2) When processing decorative yarn → rabbit hair fiber and hemp fiber blended strong twisted yarn, semi-worsted processing technology is used.

1) Semi-worsted processing process:

Raw material → bulk fiber primary color or dyeing → artificial small amount mixing → oiling with wool → FB219 flat plate making machine → FA306 drawing frame (three passes) → A456 roving frame → DTM129 spinning frame → GA015 winding machine → post-processing

2) Process and key technologies of semi-worsted production:

The preparation method of the above-mentioned semi-worsted rabbit hair fiber and hemp fiber blended yarn comprises successively raw materials and wool oiling, sliver making, drawing frame, roving and spun yarn operations, and is characterized in that:

In the process of raw materials and wool refueling, because rabbit hair is light in texture, soft to the touch, and low in density, it is easy to produce flying hairs during processing. More, especially at the outlet of the carding machine, the wool net is easy to break, and the wool top is easy to break, which affects the processing of the subsequent process. In addition, because most of the fiber structure is the medullary layer, the strength is low, and the fibers are easy to break during the carding process, which reduces the length of rabbit hair and increases the short hair rate. Therefore, it is more difficult for rabbit hair technicians than other animal fibers. , in order to reduce fiber damage and reduce the influence of static interference, improve fiber cohesion and spinnability, add appropriate amount of wool oil, anti-slip agent and antistatic agent, etc., generally add 0.7-1.1% for oil, and add water for 7-18%, add antistatic agent to 1.25-1.98%, and use it after sealing for 24 hours to ensure that the hair oil agent is fully absorbed by all raw materials and achieve a balanced moisture regain on the machine; the temperature and humidity of the workshop should be adjusted reasonably to ensure that all The production process can proceed normally.

In the process of carding and making sliver, because the fiber is short and the length of the dispersion is large, in the carding process, by adopting a reasonable speed of the cylinder and doffer to increase the carding, appropriately enlarge the carding distance, and adopt a reasonable cylinder and doffer speed. The ratio of the linear speed of the rollers enables the fibers to be transferred smoothly to ensure that the fibers are mixed evenly, reducing damage to the fibers and reducing the chance of hair particles. The relative speed of the workshop should be controlled at 60-78% to reduce the adverse effects of static electricity. The output weight is 15.8-19.2g/5m, the output speed is 34.5-46.0m/min, the wool feeding amount is 36.0-50.0g/time, the licker-in speed is reduced to 530-670r/min, and the cylinder speed is 290-340r/min. min, cover speed 60-112mm/min, doffer speed 17.5-24.2r/min, cylinder-doffer interval 0.15-0.19mm, cylinder-cover interval 14, 12, 13, 13 , 14/1000 inches.

In the drawing process, in view of the large difference between the two fibers, in order to ensure that the two fibers are mixed evenly, the mixing ratio is correct, and the parallelism of straightening is consistent, the design of the drawing process should adopt heavy pressure and an appropriately large spacer. distance. In the production process, the draw frame process should reasonably select the roller center distance, roller pressure and pressure distribution, draft ratio, etc. The drafting ratio of the front tension is based on the fact that the cotton web can be bundled and drawn down smoothly without wrinkling, and a smaller drafting ratio is beneficial to evenness. The relative humidity of the workshop is controlled at 60-75%, and the temperature is controlled at 22.0-27.5°C; the first and third lanes are combined with 6 pieces, and the second and third lanes are combined with 8 pieces. The speed should not be too high, and the speed should be 158-210m/min. The head is fed with 6 feeders, the weight of the sliver is 16.8-19.8g/5m, the gauge is 14×25mm, and the horn diameter is 3.6-3.8mm; The distance is 13×24 mm, the diameter of the horn is 3.4-3.6mm; the three parallels are fed by 8 pieces, the weight of the bars is 15.6g/5m, the distance is 12.5×23mm, and the diameter of the horn is 3.2-3.6mm;

In the production process of the roving process, the roving process should reasonably select the roller center distance, roller pressure and pressure distribution, draft multiple, etc. The pressure of the rollers should be properly controlled, and the relative humidity of the workshop should be controlled at 60-67% to ensure normal production. The draft ratio is 5.4-7.2 times, the roving basis weight is 4.6-6.4g/10m, the gauge is 24.0×34.0mm, the twist coefficient is 60-78, the axial winding density is 3.165-3.385 turns/cm, and the spindle speed is 546-664r/min. Front roller speed 164-190r/min.

In the spinning process, the strong twisted yarn is twisted on the basis of the twist of ordinary yarn to increase the twist shrinkage of the yarn. The twist coefficient is generally about 2 times that of ordinary yarn, exceeding the critical coefficient. Therefore, the strength of the yarn is low, and the yarn becomes brittle during spinning in the spinning process, and there are many yarn breaks. With a certain twist coefficient, as the twist coefficient increases, the strength decreases instead. Therefore, effective technical measures are taken in the spinning process. Due to the high strength of the twisted yarn, the quality of the traveler is 1-2 sizes lighter than that of the same number of yarns, so as to reduce broken ends, solve problems such as difficult joints and heavy twisted ends. At the same time, the spindle speed and vehicle speed should be appropriately reduced so that the production can proceed normally. The distance between the jaw spacers should be relatively large to avoid hard ends. Due to the long fiber length, the roller gauge is appropriately increased to improve the evenness level and ensure the stable movement of the fiber during drafting. During the spinning process, the twisting and winding parts are clean and burr-free, and the service life of the steel ring and traveler is reasonably controlled to reduce spinning tension and tension fluctuations, which is beneficial to reducing broken ends. The workshop temperature is controlled between 30-32°C; the relative humidity is controlled at around 65%. The ring diameter is 35-45mm. Twist 1050-1380 twist/m, spindle speed 13000-15000r/min.

In the winding process, the production follows the technological principle of "small tension, small elongation, small speed, wear reduction, and elasticity preservation". The winding speed is 355-429m/min, and the winding speed should be appropriately reduced to reduce damage to the strong twist yarn, maintain the wear resistance of the strong twist yarn, and create conditions for the smooth progress of the next process.

Step 3: Retrieval treatment: use water-soluble vinylon produced by Shanghai Quanyu Company, with a dissolution temperature of 95°C, take 60 groups of yarns, take out a group every 6 minutes, wash and dry, weigh and analyze.

The fourth step is the hollow spindle fancy twister, which combines several different processes such as spinning, color matching, twisting, and winding on the same machine. Choose YCHN--505 fancy twisting machine, its drafting mechanism is composed of five rollers, and process multifunctional anti-virus health care hollow braid fancy yarn.

(1) Production principle: It mainly uses the overfeeding method of strong twisted decorative yarn to make it in a relaxed state, because of its large resilience, it will kink and produce irregular braids, and then attach to the core The middle of the thread and the fixed thread becomes a braided thread, and the range of the superfeeding core yarn of the decorative yarn is generally controlled between 1.95-3.59 times. The twist of decorative yarn is controlled at 1050-1380 twists/m, and the twist should not be too large, otherwise it will affect the quality of bobbin forming, not only causing unsmooth unwinding, but also easy to cause congestion at the entrance of the hollow spindle, which will affect the hollow braid pattern Yarn quality.

(2) Process: ① Hang up the core yarn; ② Wind the fixed yarn to the fixed thread tube, and confirm that the winding direction of the fixed thread is the same as that of the hollow spindle. ③Insert the prepared wire tube into the hollow ingot, and pull out the hollow ingot; ④Lead out the core wire through the tensioner, core wire spring, and pass through the core wire porcelain tube, and the core wire pressure roller is in the suspended position; ⑤Lift up Cradle, introduce the yarn into the rear bell mouth, remove the random fibers at the end of the yarn, and make the yarn end between the front roller and the rear roller; According to the direction of the movement of the false twisting hook, the movement direction of the false twister should be the same as that of the hollow spindle; ⑦Introduce the core yarn and the fixed thread into the output roller; push into the hollow spindle, and the hollow spindle is at work Position; ⑧Depress the cradle, the roving draft works, and the yarn sliver is output at the front roller mouth; press down the core thread roller, and the core thread tension is pulled; ⑨Remove the badly formed part of the core thread lead-out end, and lead the yarn out through the groove drum Bobbin, start winding work.

Preparation of the second elastic braid fancy yarn:

The core yarn of the elastic braid fancy yarn is wrapping yarn processed by Yasser fiber, coconut carbon fiber, silver fiber, seaweed fiber and spandex filament; the fixed yarn is negative ion polypropylene filament and antibacterial polyester filament, and the decorative yarn is Strong twist yarn blended with camel plush fiber and apocynum fiber.

The first step is to spin the core yarn of the fancy yarn. The process flow of the system is as follows: opening and cleaning→carding→drawing (three passes)→roving→spinning→post-processing.

Yasser fiber, coconut charcoal fiber, silver fiber, seaweed fiber → automatic weighing and mixing → FA042 automatic weighing machine → FA016 automatic cotton mixing machine → FA106A comb roller opener → FA161 vibrating cotton feeder → FA141A single-hand lapping machine is used to make rolls → FA201 carding machine → FA326A drawing frame (three lanes) → FA481 roving frame → FA507 spinning frame → GA012 winding machine → baling.

In the cotton opening and cleaning steps, the disc automatic plucking machine is not used, and the minimum opening and blowing is followed to prevent fiber damage and entanglement; the control of nodding is strengthened to reduce the probability of fiber scattering and neps. Use free strike or comb needle beater as much as possible, mainly loose and light beats, so that the fibers can be fully decomposed and damage can be reduced. The distance between the dust bars of the automatic cotton blender is generally between 9.5-12.5mm. The inlet between the cotton stripper and the dust bar is controlled between 6-18mm, and the outlet is controlled between 8-22mm. The speed of the beater directly affects the stripping of the fiber blocks and the impact of the fiber blocks on the dust grid, and has an impact on both opening and impurity removal. If the beater's rotating speed is too high, it is easy to return flowers and form bunches or neps. The speed of the cotton stripper is controlled between 350-750r/min. Increase the beater speed within a certain range and increase the number of blows, which can improve the effect of loosening and removing impurities. But the beater speed is too high, it is easy to break impurities and damage fibers. Under normal circumstances, the beater's speed is controlled between 900-1000r/min. The distance between the beater and the working surface of the balance curved rod, under normal circumstances, the distance is controlled between 8.5-10.5mm. The inlet distance between beater and dust bar is 8-10mm, and the outlet distance is 16-18mm. The distance between the dust stick and the dust stick is controlled between 5-8mm. The speed of the carding cylinder is controlled at 430-630r/min, the speed of the fan is generally 1250-1600r/min, the speed of the lap roller is 10.5-14.5r/min, and the basis weight of the chemical fiber roll is 340-420g/m.

When processing Yassel fiber, etc., it is necessary to choose a licker-in saw blade with a small working angle and a large tooth density. Correct selection of cylinder and doffer card clothing specifications is the key problem in carding and transfer. The choice of flat card clothing requires that the needle tip can bear a large carding load, and it is not easy to wind around the cylinder and fill the fiber. The distance between the cylinder and the doffer should be relatively small; the distance between the opening of the front upper cover plate and the cylinder is generally slightly larger than that of spinning cotton; The spacing must be accurate. The flat speed affects the impurity removal efficiency and the flat flower amount. Since the chemical fiber has less impurities and the short fibers are easy to be discharged in the flat flower, the flat speed can be controlled at an appropriate low level. Generally, the cylinder speed is controlled at 320 -390r/min, the licker-in speed is controlled at 590-820r/min. The cover plate speed is controlled at 70-129mm/min, and the doffer speed is 22.5-27.5r/min. In the drawing process, it is necessary to ensure that the fibers are stretched in parallel to achieve a relatively complete separation state, and to control the short segment unevenness, weight unevenness and weight deviation of the sliver at a better level, and it is also required to mix polyester and cotton fibers. Homogeneous and accurate mixing ratio. The process parameters are: the gauges of the three drawing rollers are all 13-14.5×20.5-24.5mm, the pressure of the three drawing rollers are all 30×32×30kg, the weight is 16.60-18.18g/5m, and the horn diameter is 3.4- 3.8mm, delivery speed 173-215m/min.

In the roving process, due to the large draft force, a larger roller holding distance should be used. Whether the roving process configuration is reasonable has a great relationship with the quality of the finished product. In the production process, the roller center distance, roller pressure and pressure distribution, draft ratio, etc. should be reasonably selected in the roving process. The process parameters are: front roller speed 169-225r/min, roving basis weight 4.10-5.47g/10m, roving twist 4.30-4.74g/10cm, axial winding density 3.225-3.495 turns/cm, roller gauge 23.0-26.5 ×31.0-34.5mm, spindle speed 539-720r/min, pressurization amount 24-28×15-17×20-25Kg/double spindle, jaw gap 3.5-5.5mm, front collector 6.2-8.5mm.

When spinning in the spinning process, the FA507 spinning frame is used, and the ring spinning frame is modified, and a set of spandex filament positive feeding device is installed to produce wrapping yarn (spandex filament). The process parameters are: roller gauge 19.5-22.5×33.5-35.0mm, pressurization amount 18×12×14kg/double spindle, spindle speed 13400-15620r/min, front roller speed 171-220r/min, jaw gap 2.5 -3.0mm. In order to ensure that the life in the workshop is easy to do, it is necessary to strictly control the temperature and humidity in the workshop to reduce the bad phenomena such as winding rollers and rubber rollers caused by static electricity; to prevent a large number of yarn defects due to excessive flying flowers in the production process of the workshop; in addition, in order to To ensure that the yarn is even and dry, in terms of spinning equipment, select high-quality spinning equipment, such as pressure rod upper pin, pressure rod jaw spacer, new rubber roller, ceramic yarn guide hook, fluorine-coated steel ring traveler, etc. , it can significantly improve the yarn quality.

In the process of winding process, according to the characteristics of elastic wrapping yarn, the process principle of "reducing wear, maintaining elongation, maintaining elasticity, low elongation, low speed and low tension" should be followed in production, and the process parameters should be selected reasonably. Keep the mechanical condition in good condition and keep the physical and mechanical properties of the original yarn as much as possible. Use the GA012 winder without electronic yarn clearer to ensure that the winding channel is clean. Process parameters: winding speed 310-470m/min, tension ring 5- 10g, winding density 0.429g/cm ³ , guide distance 69-87mm.

The second step is to select fixed yarn and decorative yarn. Among the multi-functional, multi-component, multi-pattern and multi-color elastic braided fancy health care yarn products: fixed yarn → negative ion polypropylene filament, antibacterial polyester filament; decorative yarn →Camel plush fiber and apocynum fiber blended strong twisted yarn.

(1) When processing decorative yarn → camel plush fiber and apocynum fiber blended strong twisted yarn, semi-worsted processing technology is used.

1) Semi-worsted processing process:

Raw materials→Natural color or dyeing of loose fibers→Mixing in small quantities by hand→Adding oil with wool→FB219 flat frame making machine→FA311 drawing frame (three-pass)→FA481 roving frame→FA507 spinning frame→GA012 winding machine → post-processing

2) Process and key technologies of semi-worsted production:

The preparation method of the above-mentioned semi-worsted camel plush fiber and apocynum fiber blended yarn comprises successively raw materials and wool oiling, sliver making, drawing frame, roving and spun yarn operations, and is characterized in that:

In the raw material and wool oiling process, adding wool oil can increase the wettability of fibers, reduce the adverse effects of static electricity, reduce the damage of fibers, increase the softness and toughness of fibers, and make the fibers not easy to break when carding, and To improve the cohesion between fibers and improve the spinnability of fibers, add appropriate amount of wool oil, anti-slip agent and antistatic agent, etc., generally add oil at 0.6-1.2%, add water at 6-16%, add antistatic agent 1.28-1.82%, and sealed for 24 hours before use, to ensure that the crude oil agent is fully absorbed by all raw materials to achieve a balanced moisture regain on the machine; the temperature and humidity of the workshop should be adjusted reasonably to ensure that the production of each process can be carried out normally.

In the carding and sliver making process, it is the key to control the weight unevenness and short hair rate of the sliver. Reasonably select the cylinder speed, optimize the gauge of each carding original, appropriately enlarge the gauge between the cotton feeding plate and the licker-in roller, and increase the gauge between the cover plate and the cylinder. The speed of the cover plate is reasonably controlled to reduce the cost of the cover plate and improve the production rate. Selecting a reasonable card clothing, adopting a suitable basis weight and low speed can reduce fiber damage, reduce the content of short pile and hair particles in the sliver, and create conditions for ensuring the quality of the yarn. The relative speed of the workshop should be controlled at 60-70% to reduce the adverse effects of static electricity. The process parameters are: sliver weight 15.9-19.8g/5m, sliver speed 37.5-45.0m/min, wool feeding amount 34.0-49.0g/time, licker-in speed reduced to 570-660r/min, cylinder speed 300 -340r/min, cover plate speed 68-100mm/min, doffer speed 18.5-24.5r/min, cylinder-doffer interval is 0.15-0.18mm, cylinder-cover plate interval is 15, 13, 14, 14, 15/1000 inches.

In the drawing process, in view of the large difference between the two fibers, in order to ensure that the two fibers are mixed evenly, the mixing ratio is correct, and the parallelism of straightening is consistent, the process parameters are: the relative humidity of the workshop is controlled at 60-73%, the temperature Control at 23.5-27.0°C; use 6 merging for the head and merging, 7-8 merging for the second and third lanes, the speed should not be too high, use 168-200m/min, 6 feeding for the head and sliver output Weight 16.2-18.8g/5m, Gauge 13-14×25-26mm, Horn diameter 3.6-3.8mm; Two parallels are fed with 8 strands, output weight 15.8-17.9g/5m, Gauge 12.5-13×24 -25 mm, horn caliber 3.4-3.6mm; triple paralleling adopts 8 feeders, output weight 15.2-15.6g/5m, gauge 12-12.5×23-24mm, horn caliber 3.2-3.6mm.

In the production process of the roving process, the roving process adopts the principle of "large gauge, heavy pressure, small tension, and small twist coefficient". The draft distribution of the roving frame is mainly determined by the draft form and the total draft multiple, and at the same time refer to factors such as the sliver weight and roving weight. The fiber length is long, and the drafting force in the spinning process is large, so a larger roller holding distance is adopted, and the roller pressure is 20-25% larger than that of spinning pure cotton. The relative humidity of the workshop is controlled at 60-67% to ensure normal production. The process parameters are: draft ratio 5.8-7.6 times, roving basis weight 4.2-5.8g/10m, gauge 23.5-25×33.0-35mm, twist coefficient 62-82, axial winding density 3.115-3.375 turns/cm, ingot Speed 540-685r/min, front roller speed 169-195r/min.

In the spinning process, the principle of "big gauge, heavy pressure, and small additional friction" is adopted in the production process. The strong twisted yarn is twisted on the basis of the twist of ordinary yarn to increase the twist shrinkage of the yarn. The twist coefficient is generally about 2 times that of ordinary yarn, exceeding the critical coefficient. Therefore, the strength of the yarn is low, and the yarn becomes brittle during spinning in the spinning process, and there are many yarn breaks. With a certain twist coefficient, as the twist coefficient increases, the strength decreases instead. Therefore, effective technical measures are taken in the spinning process. The strong twist yarn has a large twist, and the twist unevenness during the twisting process is relatively large, and even weak twist yarn appears, which not only affects the strength of the single yarn, but also affects the smooth progress of the subsequent process. Therefore, it is necessary to check and adjust the roving tension frequently to reduce the tension difference between the front and rear rows. Reduce spindle speed difference and reduce viscosity unevenness. The front roller pressure is generally around 11-17daN/double spindle, the front middle roller pressure ratio is in the range of 1.6-2.1:1, and the rear roller pressure is determined according to the distance of the rear zone, the draft ratio of the rear zone and the twist coefficient of the roving, etc. , generally close to or slightly greater than the middle zone pressure. Use a new type of apron, the apron should be elastic, which helps to enhance the friction circle. During the production process, the apron should not be too tight, as it will weaken the elasticity, and it should not be too loose, as it will cause the apron to snooze, which is detrimental to the quality. The process parameters are: the workshop temperature is controlled between 30-32°C; the relative humidity is controlled at about 65%. The ring diameter is 35-45mm. Twist 1100-1460 twist/m, spindle speed 13000-14900r/min.

In the winding process, the production follows the process principle of "light tension, low elongation, low speed, less wear and elasticity". The winding speed is 335-450m/min, the tension ring is 7-14g, the winding density is 0.425g/cm ³ , the yarn guiding distance is 70-90mm, and the winding speed and winding tension are appropriately reduced to reduce the damage to the strong twisted yarn. Keep the wear resistance, strength, appearance and physical and mechanical properties of the strong twist yarn as much as possible.

The third step is the hollow spindle fancy twisting machine, which combines several different processes such as spinning, color matching, twisting, and winding on the same machine. Choose YCHN--505 five-roller fancy twisting machine, whose drafting mechanism is composed of five-rollers, and process multi-functional, multi-component, multi-pattern, multi-color elastic braid fancy health care yarn. The structure of fancy yarn is composed of three components: core yarn, decorative yarn and fixed yarn. The core yarn bears strong force and is the main yarn; Then wrap it around the periphery of the decorative yarn to fix the pattern.

(1) Production method: It mainly uses the overfeeding method of strong twisted decorative yarn, so that in a relaxed state, because of its large resilience, it will kink and produce irregular braids, and then attach to the core The middle of the wire and the fixed wire becomes a braided wire. Overfeed elastic braid fancy yarn is based on one or two core yarns, which are sent out at a fixed speed; while the other strong twist decorative yarn is sent out at a speed 1.7-3.5 times higher than the core yarn , The twist of the strong twisted decorative yarn is controlled at 1100-1460 twists/m, and the twist should not be too large, otherwise it will affect the quality of the bobbin forming, not only causing unsmooth unwinding, but also prone to congestion and other adverse phenomena at the entrance of the hollow spindle, affecting the hollow core. The quality of braid fancy yarn.

(2) Process: the core yarn passes through the yarn guide (yarn guide hook), passes through the back roller, the yarn guide rod, passes through the porcelain tube and meets the decorative yarn, and the decorative yarn passes through the yarn guide and front roller, and merges with the core yarn into the hollow The spindle tube passes through the hollow spindle together with the fixed yarn, makes a circle on the false twister, twists to become a fancy yarn, and is wound onto the yarn bobbin through the output roller, yarn guide rod, and grooved drum.

(3) Setting of process parameters: hollow ingot speed 350-490r/min, ring spindle speed 340-430r/min, upper twist 370-580T/m, lower twist 305-470T/m, output line speed 3.50-7.00r /min, the draft ratio 1 is 0.37-0.65, the draft ratio 2 is 3.50-4.50, and the speed ratio is 0.65-0.85.

Preparation of the third porous braid fancy yarn:

Porous braid fancy yarn The core yarn is a hollow blended yarn processed from silver antibacterial and deodorant fiber, coffee charcoal fiber, platinum fiber and Porel hollow fiber; the fixed yarn is double-resistant acrylic fiber, triangular polyester fiber, negative ion viscose fiber Hollow yarn blended with permanent vinylon filament; decorative yarn is strong twisted yarn blended with hollow polyester fiber, mercerized wool fiber and mulberry fiber.

The percentage by weight of each substance in the core yarn is: 10-70% silver antibacterial and deodorant fiber, 10-70% coffee charcoal fiber, 10-70% platinum fiber and 10-70% Porel hollow fiber; The weight percentage is: 10-80% double-resistant acrylic fiber, 10-80% triangular polyester fiber and 10-80% anion viscose fiber; the weight percentage of each substance in the decorative yarn is: 10-80% hollow polyester fiber, 10- 80% mercerized wool fiber and 10-80% mulberry fiber.

The technical process of preparation: spinning the core yarn of fancy yarn → selecting fixed yarn and decorative yarn → processing and spinning porous braided fancy health care yarn → processing knitted fabric → performance test and analysis.

The first step is to spin the core yarn of fancy yarn. The core yarn is silver antibacterial and deodorant fiber, coffee charcoal fiber, platinum fiber, and coffee gold and silver hollow blended yarn processed by Porel hollow fiber.

1) The process flow of the blended spinning system is as follows: opening and cleaning → carding → drawing (three passes) → roving → spinning → post-processing.

Silver antibacterial and deodorant fiber, coffee charcoal fiber, platinum fiber, Porel hollow fiber → automatic weighing and mixing → FA042 automatic weighing machine → FA017 automatic cotton mixing machine → FA106A comb roller opener → FA161 vibration feeding Machine → FA142 type single-hand lapping machine to make rolls → FA201 carding machine → FA306 drawing frame (three lanes) → FA481 roving frame → FA509 spinning frame → GA013 winding machine → baling .

The opening and cleaning process is similar to the opening and cleaning process of hollow braid fancy yarn.

In the carding process, in order to meet the requirements of further processing in the subsequent process, the fibers should also be formed into uniform strip-like semi-finished products. Therefore, the quality of the raw sliver produced in the carding process directly affects the quality of the spun yarn, and the quality of the spun raw sliver is required Indicators, such as the unevenness of the sliver, the unevenness of the weight of the sliver and the nep impurities of the sliver, etc. must meet the design requirements. The principle of carding process design is "strong carding, light weight, low speed, more recovery, small tension, easy transfer, fast transfer, small pressure, tight gauge, strong carding, smooth and smooth passage, anti-blocking, Large speed ratio, suitable gauge, and the process principle of "five sharps and one accurate".

In the drawing process, the internal structure of the sliver is improved, the fibers are straightened and paralleled by drafting, the separation degree of the fibers is improved, the movement of the fibers is effectively controlled, and the unevenness of the cooked sliver is controlled within a certain range. The principle of the process design of the drawing frame is "selection of new rubber rollers and rubber rings, suitable gauge, stable grip, strong control, uniform draft, smooth draft, multiple merging, heavy pressure, light weight, large gauge Distance, low speed, anti-winding".

In the roving process, the roving process must apply an appropriate twist to the sliver, so that the roving has a certain strength to withstand the tension of the roving winding and further processing in the spinning frame, and prevent accidental draft and elongation. After twisting, the compactness between fibers increases, which is also conducive to the drafting effect of the spinning frame and ensures the quality of the spinning. The principle of roving process design is "selection of new special parts, light weight, large gauge, heavy pressure, large twist, small tension, middle axial and radial winding density, small elongation, small rear draft, Small jaws, moderate collector caliber".

In the spinning process, in the actual production process, the design of pressure, roller gauge and draft multiple must be compatible with the draft force to ensure high-quality products. The principle of spinning process design is "select new spinning parts, large gauge, medium twist, heavy pressure, shot medium hard rubber roller, medium speed, small back draft, small jaw, suitable temperature humidity".

The second step is to select the fixed yarn and decorative yarn. Among the multi-functional, multi-component, multi-pattern and multi-color porous braid fancy health care yarn products: fixed yarn → double-resistant acrylic fiber, triangular polyester fiber, negative ion viscose fiber, water-soluble vinylon fiber filament blended hollow yarn; decorative yarn→hollow polyester fiber, mercerized wool fiber, mulberry fiber blended strong twist yarn.

(1) When processing fixed yarn → double-resistant acrylic fiber, triangular polyester fiber, anion viscose fiber, water-soluble vinylon fiber filament blended hollow yarn, the process flow similar to the first step above is adopted.

The core-spun yarn processed by double-resistant acrylic fiber, triangular polyester fiber, negative ion viscose fiber and water-soluble vinylon fiber filament is hollow yarn after de-dimensionalization. The production process parameters are as follows:

In the cotton opening and cleaning step, the disc automatic catching machine is not used, and the impact point should be reduced as much as possible. The weight of the roll should not be lower than 410g/m. If it is too light, it will easily cause holes and increase the weight unevenness. Comb needle beaters are used, and the speed of the comb needle beaters is controlled at 420-605 rpm. The single beater roll machine also uses comb needle beaters, and the speed of the comb needle beaters is controlled at 530-745 rpm; the comprehensive beater speed is controlled at 600 Between -850r/min, the distance between the beater and the dust rod is 9-12mm at the inlet and 16-20mm at the outlet. The distance between the dust stick and the dust stick is controlled between 7-11mm. Fan speed 1150-1290 rpm, lap roller speed 11.5-13.5 rpm.

The quality of the sliver produced in the carding process directly affects the quality of the spun yarn, and the quality indicators of the spun sliver, such as the unevenness of the sliver, the unevenness of the weight of the sliver, and the nep impurities of the sliver, must meet the design requirements. In general, the licker-in speed is 570-860 rpm, the cylinder speed is 325-380 rpm, the cover plate speed is 71-112mm/min, the doffer speed is 20.5-24.5 rpm, and the distance between cylinder and doffer 0.45mm, 0.37mm, 0.35mm, 0.35mm and 0.38mm, the distance between cylinder and doffer is 0.15-0.17mm, the distance between licker-in roller and cylinder is 0.27-0.29mm, the distance between feeding board and licker-in roller Gauge distance is 0.21-0.25mm, distance between dedusting knife and licker-in roller is 0.33-0.37mm. The workshop temperature is controlled between 26-32°C; the relative humidity is controlled at around 62-67%.

The quality of the cooked sliver produced by the drawing frame directly affects the quality of the spun yarn. The drawing process requires that the quantity of spinning meet the design requirements, and the unevenness of evenness and weight should be small. In the drawing process, the gauge of the three drawing rollers is 14-16×22-25mm, and the pressure of the three drawing rollers is 31×33×31×7kg; the roving process must apply appropriate pressure to the sliver Twisting, so that the roving has a certain strength to withstand the tension of the roving winding and further processing in the spinning frame, preventing accidental draft and elongation. After twisting, the compactness between fibers increases, which is also conducive to the drafting effect of the spinning frame and ensures the quality of the spinning. In the roving process, the spindle speed is 570-720r/min, and the front roller speed is 170-225r/min.

When spinning in the spinning process, it is necessary to modify the ring spinning frame and install a set of water-soluble vinylon filament positive feeding device so that a water-soluble vinylon filament can be fed from the front drafting area of the spinning frame (front behind the top roller), and output the staple fiber strips after drafting at the nip of the front roller at the same time, properly control the tension of the filaments, twist the same spindle to form core-spun yarns, and spin them after fiber removal Chengzhu lotus root silk Laizhu Kanglun hollow yarn (water-soluble vinylon filament).

(2) When processing decorative yarn → hollow polyester fiber, mercerized wool fiber, and mulberry fiber blended strong twisted yarn, semi-worsted processing technology is used.

1) Semi-worsted processing process:

Raw materials→Natural color or dyeing of bulk fibers→Mixing in a small amount by hand→Water refueling→FB219 flat frame making machine→FA317 drawing frame (second pass)→TJFA458A roving frame→DTM129 spinning frame→GA013 winding machine → post-processing

2) Process and key technologies of semi-worsted production:

The preparation method of the above-mentioned semi-worsted hollow polyester fiber, mercerized wool fiber, and mulberry fiber blended yarn includes the steps of adding oil to raw materials and wool, sliver making, drawing frame, roving and spun yarn successively, and is characterized in that:

In the oiling process of raw materials and wool, when mixing wool, properly increase the number of times of false mixing to ensure that the raw materials are evenly mixed. According to the ratio of water, crude oil and antistatic agent 13-15:1:2, mix in a certain proportion Spray it on the fiber, seal it in the wool bin and let it sit for 24-36 hours, so that it can be fully mixed with hair oil and water, which is conducive to smooth processing and ensures the improvement and stability of carding quality. In the process of kneading, the method of horizontal laying and straight picking should be adopted to ensure uniform mixing.

In the process of carding and making sliver, the stuffed raw materials are fed into the carding machine, and the technological principles of frequent feeding, thin feeding, uniform feeding, light weight, low speed, medium distance and small speed ratio are adopted to ensure that the equipment is in the best condition. In good condition, strengthen the control of the quality of wool nets. Once problems are found during production, they must be resolved in time, and the problematic carding strips cannot be allowed to flow into the next process, so as not to affect the quality of semi-finished products in the next process. By appropriately reducing the rotation speed of the licker-in roller and the cylinder, and appropriately enlarging the gauge of each carding part, the damage to the fiber can be reduced. Reasonably control the linear speed ratio of the cylinder and the licker-in roller, properly control the quantity of the carding sliver, and ensure the smooth transfer of fibers. The relative speed of the workshop should be controlled at 60-73% to reduce the adverse effects of static electricity. The process parameters are: sliver weight 17.1-21.8g/5m, sliver speed 39.5-46.5m/min, wool feeding amount 33.5-45.2g/time, licker-in speed reduced to 580-680r/min, cylinder speed 310 -350r/min, cover plate speed 76-110mm/min, doffer speed 19.5-23.5r/min, cylinder-doffer interval is 0.15-0.17mm, cylinder-cover plate interval is 15, 13, 14, 14, 15/1000 inches.

In the drawing process, in view of the large difference between the three fibers, in order to ensure that the three are mixed evenly, the mixing ratio is correct, and the parallelism of straightening is consistent, the draft ratio in the rear area of the first draw frame is controlled at 1.5-2.2 Between multiples, the total draft multiple is less than the number of combined roots. The draft ratio in the rear zone of the second draw frame is controlled between 1.04-1.22 times, the main draft zone is controlled between 6-8 times, and the total draft ratio is slightly greater than the number of combined roots. The pre-tension draft ratio is generally controlled between 0.95-1.05 times, and the process parameters are: the relative humidity of the workshop is controlled at 60-70%, and the temperature is controlled at 24.0-27.0°C; Lowering, using 170-220m/min, sliver weight 17.0-19.8g/5m, gauge distance 13-14×25-26mm, horn diameter 3.4-3.8mm; 2 and 8 feeding, sliver weight 16.0-17.8 g/5m, spacing 12.5-13×24-25mm, horn diameter 3.4-3.8mm.

In the roving process, the quantitative and total draft ratio of the roving should be reasonably selected. In order to improve the uniformity of the roving, a new drafting device should be used on the roving frame. Reasonably select process parameters, determine reasonable temperature and humidity, maximize the overall quality of the roving, provide semi-finished products with stable quality to the spinning frame, and prepare for the final production of high-quality spun yarn. The process parameters are: draft ratio 6.2-7.9 times, roving basis weight 4.12-4.78g/10m, gauge 23.0-25.0×33.0-35.0mm, twist coefficient 69-85, axial winding density 2.715-3.385 turns/cm, Spindle speed 620-725r/min, front roller speed 170-225r/min.

In the spinning process, the twist coefficient of strong twist yarn is higher than that of normal yarn, and its twist coefficient is generally about 2 times that of ordinary yarn, exceeding the critical coefficient. The twist coefficient of the spun yarn exceeds the critical twist coefficient of the yarn, and the yarn strength is lower than that of the conventional woven yarn. The larger the twist coefficient, the lower the yarn strength, and the higher the weight CV% and strength CV%. At the same time, in order to obtain relatively High production efficiency, the spinning spindle speed is generally not lower than the same number of weaving yarns. Compared with ordinary yarn, strong twisted yarn has less hairiness on the surface, is relatively smooth, and feels a little harder. The process parameters are: workshop temperature is controlled between 25-32°C; relative humidity is controlled at 63-68%. The ring diameter is 42-45mm. Twist 1150-1560 twist/m, spindle speed 13000-14900r/min. The front roller pressure is generally around 11-19daN/double spindle, and the front-middle roller pressure ratio is in the range of 1.60-2.12:1.

In the winding process, the production follows the process principle of "light tension, low elongation, low speed, less wear and elasticity". The winding speed is 319-438m/min, the tension circle is 8-15g, the winding density is 0.422g/cm ³ , the yarn guide distance is 71-93mm, and the lower winding speed and winding tension can reduce the stress on the strong twisted yarn. damage, reduce winding hairiness, and maintain the evenness, wear resistance, strength, appearance and physical and mechanical properties of strong twisted yarn to the maximum extent.

Step 3: Retrieval treatment: use water-soluble vinylon produced by Shanghai Quanyu Company, with a dissolution temperature of 95°C, take 60 groups of yarns, take out one group every 6 minutes, wash and dry, and weigh and analyze (Figure 1).

In the fourth step, on the YCHN--303 three-roller fancy twisting machine, the technology of processing porous braid fancy health care yarn is as follows:

(1) Technological process: On the YCHN--303 three-roller fancy twisting machine, the processing of porous braided fancy health care yarn needs to go through two processes. In the first process, the core yarn passes through the yarn guide (yarn guide) Hook) passes through the front roller, yarn guide rod, passes through the porcelain tube and meets the decoration yarn, and the decoration yarn passes through the yarn guide and back roller, and merges with the core yarn into the hollow spindle tube; in the second process, the base yarn is the first process The strong twisted yarn (decorated yarn) in the center is twisted with the core yarn in the way of overfeeding, the base yarn passes through the front roller, the fixed yarn passes through the rear roller, and then passes through the hollow spindle together, rakes a circle on the false twister, passes through The output roller, yarn guiding rod and groove drum are wound onto the yarn bobbin.

(2) Production principle: The braided thread is composed of a core yarn, a decorative yarn and a fixed yarn. Using the overfeeding method of strong twisted yarn (decorated yarn), in the relaxed state, due to the high resilience, it will be kinked to produce irregular small braids, which are attached to the middle of the core thread and the fixed thread to form a braid. On the YCHN--303 three-roller fancy twisting machine, the processing of the porous braided fancy health care yarn needs to go through two processes. In the first process, the strong twisted yarn (decorated yarn) is overfeeded with the core yarn Co-twisting, generally the overfeed ratio of decorative yarn and core yarn is controlled between 1.9-3.2 times, the core yarn passes through the front roller, and the decorative yarn passes through the rear roller; in the second process, the overfeed ratio of the fixed yarn is reasonably controlled. Size, overfeed ratio of fixed yarn and base yarn, the range is controlled at 1.00-1.18 times.

(3) Setting of process parameters: hollow spindle spindle speed 35.0-92.0r/min, front roller speed 1.8-8.2m/min, rear roller speed 1.0-3.4m/min, middle roller speed 2.8-14.5m /min, output roller speed 1.70-31.0m/min, core roller speed 1.0-11.0m/min, ring diameter 75mm. The twist direction of the base yarn (co-twisted decorative yarn and core yarn) is S twist, and the twist direction of the porous braid fancy health care yarn (fixed yarn and base yarn) is Z twist.
