Description

Outlast fiber pure or blended melange spinning yarn and production method thereof

technical field

The invention relates to a melange spun yarn which is purely spun with air-conditioning fibers or blended with other fibers.

Background technique

Outlast air-conditioning fiber is a kind of polyacrylonitrile fiber with heat regulation function. The heat-sensitive phase change material wrapped in microcapsules is used in the fiber. This material has the function of absorbing, storing and releasing heat in the form of latent heat. In the temperature change, it can be converted into solid and liquid, thereby achieving the effect of heat absorption and heat release. Therefore, it can respond to changes in the external environment temperature on the skin, and has a buffering effect on temperature changes. Air-conditioning fibers can be applied to all kinds of garments and accessories, including underwear, T-shirts, pajamas, hats, gloves, socks, shoes, jackets, raincoats and outerwear, etc., which can meet the pursuit of comfort and leisure, and have broad development prospects . However, the conventional spinning method produces monotonous gray yarn after dyeing, which cannot meet the needs of individual consumption, and the yarn strength is not high, which also limits the application of the fiber.

Contents of the invention

The object of the present invention is to provide a pure or blended melange spinning yarn of air-conditioning fiber, which contains 35%-100% of air-conditioning fiber and 0-65% of fine-staple cotton or long-staple cotton in the finished yarn. The yarn is rich in color , the strength is completely suitable for high-speed circular knitting machine or flat knitting machine processing, and the woven fabric can give full play to the excellent performance of air-conditioning fibers and enrich people's living needs. Fine-staple cotton or long-staple cotton is used to make up for the weak point of low yarn strength of air-conditioning fibers.

The purely spun or blended color-spun yarn of the air-conditioning fiber is a yarn made of fibers of different colors through mixed-color spinning. Single yarn or ply yarn with spinning count of 10S-45S, 35-100% air-conditioning fiber in blended yarn, 0-65% fine-staple cotton or long-staple cotton, single yarn twist of 400-1100T/m, ply yarn The twist is 210~1000T/m. The role of long-staple cotton is to make up for the weakness of air-conditioning fiber pure blended single yarn with low strength. In order to make the fabric made of this yarn have good wearing performance, spandex filaments can also be added to the mixed-color spinning to make air-conditioning fiber-colored spinning spandex core-spun yarn.

The technological process of the present invention is: fiber dyeing, spinnability treatment of dyed air-conditioning fiber, weighing, mixing, cleaning, carding, first doubling, second doubling, third doubling (color toning and complementary colors), roving, spun yarn, winding, The strands also need to be winded by the doubling and twisting machine.

The specific spinning process is as follows:

1. According to product requirements, dye various fibers to make the fibers have various colors that meet the requirements. At the same time, spinnability treatment is performed on the dyed air-conditioning fibers. The acrylic spinning oil is diluted with condensed water at a ratio of 1:6-8, the amount of oil to be controlled is 0.5-0.6% of the weight of the air-conditioning fiber, and the dyed air-conditioning fiber is oiled and put for 24 hours before use;

2. The characteristics of the bulk fiber dyeing process of air-conditioning fibers are as follows: at 90°C-100°C*40min, add scouring agent 2-3g/l for scouring; ℃/min to raise the temperature to 80℃～100℃, (determine the heating rate and holding temperature and time according to the color) hold the temperature for 40-60min, add acetic acid to adjust the pH value to 3.5-6, and hold the temperature to complete. Release the temperature at 1°C to 2°C/min to 60°C to 70°C, and then drain the liquid, and the post-treatment water condition is 60°C to 80°C*10min, 2 to 3 times.

3. According to the product color requirements, match the proportion of fibers of different colors, and weigh various fibers according to the dry weight ratio;

4. Lay up and mix the weighed air-conditioning fibers of different colors and combed colored cotton according to the regulations. If the feeding batch is large, divide it into several parts for mixing;

5. After the raw materials are well mixed, they are packed in the cleaning process, further mixed and quantitatively rolled. The dry weight of the lap is 350-450 g/m, and the length of the lap is 30-40 meters;

6. Comb the mixed-color cotton rolls into strips on the carding machine. Raw sliver weight is 18-22g/5m, doffer speed is 17-24 rpm;

7. Perform three combined drafting on the draw frame to make the fiber strips have the same weight, uniform dryness, and parallel and straight fibers. The dry weight is 14-21g/5m, the combined number is 6-8, the draft is 5.5-8.5 times, the speed is 250-350m/min; the cradle pressure is controlled in the middle and low range;

8. Draft roving on the roving frame, properly reduce the twist, reduce the speed of the vehicle, and avoid the pressure of the overweight cradle to prevent the rupture of the microcapsules. Roving dry weight 3~6g/10m, draft 5~12 times, twist coefficient 60~100, spindle speed 600~1000 rpm;

9. Spun into spun yarn on spinning frame. Properly reduce the vehicle speed, and the color of the pressure regulating block of the cradle is green (medium pressure). In order to prevent the microcapsules from breaking, the phase change material overflows and loses the air conditioning function. The dry weight of the spun yarn is 0.98-5.9 g/100 meters, the draft is 15-35 times, the twist is 400-1100T/m, and the spindle speed is 8000-15000 rpm;

It can be spun into spandex core-spun yarn after adding spandex filament on the modified spinning frame. The draft ratio of spandex yarn is 2.5 to 4.5 times;

10. Wind cone yarn on the automatic winder (Auto Coner-338). Winding speed 900-1400 m/min;

11. Carry out ply twisting on the twisting machine. Twist 210～1000T/m, spindle speed 7000～11000 rpm;

12. Wind the cone yarn on the automatic winder (Auto Coner-338). Winding speed 800-1400 m/min;

The air-conditioning fiber mixed-color spun yarn of the present invention meets the national standard, and the fabric woven by it has a smooth and clean surface, good drapability, comfortable, soft, moisture-absorbing and breathable, and good color fastness. The fiber is dyed and spun, and its air-conditioning effect is fully effective.

Detailed ways

The process flow of the embodiment is: fiber dyeing, dyed air-conditioning fiber spinnability treatment, weighing, mixing, cleaning, carding, first doubling, second doubling, third dolling, roving, spun yarn, winding. After the winding process, it is twisted and wound.

In the spinnability treatment process of dyed air-conditioning fibers, the acrylic spinning oil is diluted with condensed water at a ratio of 1:7-8, then oil and water are added according to 0.6% of the air-conditioning fiber weight, and the dyed air-conditioning fibers are stuffed for 24 hours before use.

Among them, the loose fiber dyeing process of air-conditioning fiber is scouring at 90℃～100℃*40min, adding 2～3g/l of scouring agent; Raise the temperature to 80°C-100°C, (determine the heating rate and holding temperature and time according to the color), hold the temperature for 40-60 minutes, add acetic acid to adjust the pH value to 3.5-6, and hold the temperature to complete. Release the temperature at 1°C to 2°C/min to 60°C to 70°C, and then drain the liquid, and the post-treatment water condition is 60°C to 80°C*10min, 2 to 3 times.
