Grass coral fiber Grass coral is commonly known as Manshanxiang, Guanyin tea, Jiujiehua, elderberry, etc. It is a perennial evergreen subshrub of Chrysanthemum orchidaceae. It has a beautiful shape and a fragrant fragrance in all seasons. It has extremely high medicinal, edible and ornamental values. my country is the main producing area of grass coral, and foreign producing areas are distributed in North Korea, Japan, Malaysia, the Philippines, Vietnam, Cambodia, India, and Sri Lanka. The six main components in Grass Coral are astilbin, isoflavones, rhamnosyl glucoside, tannin, zinpyridin, fencetin, and fencetin. They generally have antibacterial and anti-inflammatory effects, and have good antibacterial and bacteriostatic effects on Staphylococcus aureus, Candida albicans and Escherichia coli.

Grass coral fiber is made of natural plant ----- grass coral extract as raw material, blended with viscose fiber spinning solution. Grass coral fiber is a natural, green and environmentally friendly fiber. Grass coral extract is extracted from the natural grass coral leaf and its active ingredients are superfinely pulverized. No chemical substances are added during the extraction process.

(3) Laying: The process parameters and key technologies of the laying process: the use of a cross-lapper can change the product quality of the spunlace fabric, and the speed of the input curtain, compensation curtain, laying curtain and output curtain should be reasonably selected during production , in order to improve the uniformity and strength of the product, etc., the selection of the appropriate number of fiber mesh layers can ensure that the quantitative of the product meets the design requirements.

Feed the carded raw materials into the cross-lapper, the process parameters of the cross-lapper: line speed 33.4~41.8 m/min, trolley speed 30.7~38.4m/min, input curtain speed 40.3~41.8/min, output curtain speed 4.6~11.9m/min, 4~6 layers, width 2330~2780mm;

(4) Drafting: The process parameters and key technologies of the drafting process: the general drafting ratio is controlled at 1 to 2 times. The drafting machine is composed of 15 drafting card clothing rollers and holding card clothing rollers, forming 3 drafting zones, by rationally designing the drafting multiples of each zone, it helps to improve the arrangement of behaviors, increase the compactness, cohesion and friction between fibers, and improve the quality of spunlace products;

The drafting machine is composed of 15 drafting card clothing rollers and holding card clothing rollers, forming 3 drafting areas; the process parameters of the drafting machine: the total drafting ratio is 1.1~1.8 times, and the drafting ratio of the first roller is 7.0 ~11.0 times, the draft ratio of the second roller is 12.0~16.2 times, the draft ratio of the third roller is 8.4~19.6 times, and the draft ratio of the fourth roller is 12.4~23.6 times. The input speed of the fiber net into the drafting machine is 10.18~10.84m/min, and the output speed of the drafting machine is 15.0~16.8m/min;

(5) Spunlace: The spunlace adopts a spunlace machine, and the number of spunlace passes is 5~7. The process parameters of the spunlace machine: the first speed of the conveying curtain is 11.3~21.1m/min, and the speed of the cylinder drum is 15.5~ 29.8m/min, the second speed of the conveyor curtain is 14.8~25 m/min, the pressure (bar) is 23~65, 40~105, 60~115, 30~105, 58~110, 70~110, 67~110 . Pre-wet 3.0~6.0bar, spray hole diameter 0.12mm, hole distance 0.6mm, output speed of spunlace machine 12~18m/min;

The process parameters and key technologies of the spunlace process: (1) The spunlace pre-wet process adopts double net curtain clamping and feeding. Since the spunlace pressure is small, it has little effect on the fiber web. The fiber web must be pre-humidified before entering the spunlace area. The purpose of pre-wet is to fully absorb and utilize the energy of the hydrojet during the spunlace process. The purpose of pre-wetting: to compact the fluffy fiber web, to remove the air in the fiber web, so that the fiber web can effectively absorb the energy of the water jet after entering the spunlace area, so as to strengthen the effect of fiber entanglement. (2) When the spunlace pressure increases, the fibers in the fiber web are more tightly entangled, the fibers are interspersed with each other more times, the friction and cohesion between the fibers are larger, and the number of pores is small. On the contrary, the fiber web The entanglement between the fibers in the fiber is loose, and the number of pores increases. (3) The larger the spunlace distance, when the high-pressure water flow hits, the water flow will generate friction with the air. Due to the unbalanced surface tension and frictional resistance of the water flow, the clustering of the high-pressure water jet will decrease, resulting in a high-pressure and fine water flow. Crack and bifurcation, the energy of the high-pressure water jet becomes smaller, the center velocity of the high-pressure water jet decreases, the fibers in the fiber web are not tightly entangled, and the pores in the loose fiber web are large and large in number, which is not conducive to the reinforcement of spunlace products; Conversely, the smaller the spunlace distance, the tighter the fiber entanglement in the fiber web, the smaller the number of pores in the fiber web, and the stronger the spunlace product. (4) The number of spunlace passes generally adopts 5~7 spunlaces. When spunlace is pre-wetted, double rows of pinholes are used. The aperture of the pre-spunlace is 0.15mm. Avoid the displacement of the fibers in the fiber web, so that the entanglement effect in the fiber web is good. In the second spunlace, the aperture of the jet plate should be small, which is helpful to puncture the fibers, and the aperture is generally 0.10~0.12mm. In the third spunlace, the method of reverse spunlace is adopted, and the general aperture is 0.08~0.10mm. For the fourth and fifth spunlace, use reverse spunlace to ensure that the surface of the spunlace fabric is fine and soft, and the general pore size is 0.10~0.12mm. (5) The surface of the jet plate is required to be straight and able to withstand the impact of the high-pressure water jet, and the jet plate is made of high-strength and high-density materials. The pinholes on the water needle plate are required to be smooth, vertical and uniform, so as to ensure that the water needle jet has a good concentration and the impact energy of the water jet is increased. During production, the surface of the jet plate should be kept clean, and it should be maintained and cleaned in time according to the service cycle, so as to avoid the occurrence of undesirable phenomena such as pinhole deformation and blockage, water jet bifurcation, and high-pressure water jet instability during production, which will affect the performance of spunlace products.

The function of the support net curtain: it not only plays the role of conveying and supporting the fiber net, but also accepts the impact of spunlace, and at the same time, it also plays the role of using the reflected impact water flow after the water needle jet passes through the fiber net to re-surge the back of the fiber net. For entanglement, the thinner the silk thread on the support screen, the greater the reflection force of the high-pressure water needle, and the better the entanglement effect of the fiber web, which can significantly improve the overall quality of the spunlaced fabric. The higher the opening rate on the screen curtain, the easier it is for the high-pressure water jet to pass through the fiber net and the screen curtain, the more obvious the mesh of the processed product, and the tighter the fiber net is entangled.

The influence of fiber web speed on the quality of spunlaced fabric: when the fiber web speed is low, the time for the fiber web to withstand high-pressure water jets is longer, the impact energy on the fiber web becomes larger, and the degree of entanglement between fibers becomes larger. Strong increase. During the operation of the mesh transmission curtain, loose edges, tension changes, non-parallel guide rollers, etc. will cause the mesh curtain to move laterally (swimming), and a deviation correction device is required to keep the mesh curtain moving in the center in the lateral direction. The speed of the fiber web is: the production speed is generally 40~100mm/min.

(6) Drying: Process parameters and key technologies of the drying process: The dryer uses hot oil to circulate inside the dryer, and heats the surrounding air through the emitted heat. Negative pressure is generated around to form hot air for convection heat transfer drying to complete the purpose of drying. When drying, it is necessary to choose a reasonable hot air temperature, flow rate, wind speed, circulation volume, etc. to control the drying effect and ensure product quality. When drying, the temperature and speed should be properly controlled. If the temperature is too low, the purpose of drying will not be achieved. If the temperature is too low, the fibers will become brittle and the spunlace cloth will turn yellow. Use a dryer for drying, the process parameters of the dryer: line speed 10.1~18.9m/min, set drying temperature 110~180℃;

(7) Winding: Process parameters and key technologies of the winding process: the function of the winding machine is to cut and wind the dried spunlace products according to requirements, specifications, standards, etc., to ensure the appearance, The width and roll length meet the requirements and meet the next step of processing. The winding machine is used for winding. The process parameters of the winding machine are: winding length 300~1000m/roll, winding diameter 450~960mm, winding speed 11.0~28.8m/min.

In the step (5), the number of spunlace passes is 5-7, and the spunlace pre-wet uses double rows of pinholes. The first spunlace adopts reverse spunlace with a pore diameter of 0.08~0.10mm; the fourth and fifth spunlaces have a pore diameter of 0.10~0.12mm.

Production of facial mask: During the production process, the purification workshop should be sterilized and antibacterial, and the appropriate temperature and humidity should be adopted to ensure that the environmental sanitation conditions of the purification workshop meet the national standards, and the bacteria content should be controlled to a minimum. It mainly includes the following steps: (1) Process the spunlace non-woven mask base fabric first, and make preparations; (2) According to the technical requirements and ratio, add appropriate amount of preservatives, anti-irritant ingredients, anti-allergic substances, natural Plant extracts, nutritional liquid additives, moisturizing liquid additives, health care ingredients, moisturizing additives, anti-aging additives, functional additives, sodium hyaluronate, surfactants, oils, essences, glycerin, water, etc. Stir in a high-speed dispersion plate to form a uniform and stable mask mixed liquid; (3) Then cut the spunlace nonwoven base fabric according to the technical requirements and size, and then in the purification workshop, mix the mask mixed liquid with the spunlace nonwoven Filling the base fabric of the mask, it is necessary to ensure stable quality, so that the nutrient and moisturizing liquid and other active ingredients are enclosed in the mask, so that the skin can effectively absorb and enter when used; (4) According to the national technical conditions, packaging, signs and acceptance regulations, etc. Finally, in the purification workshop, put the mask towel into a plastic bag, seal it with an electric sealing machine, and then pack the product, which is the finished mask.
