Description

TECHNICAL FIELD

[0001] The present invention relates to a method of spinning cashmere treated with hyaluronic acid, in particular, to a hyaluronic acid cashmere spinning process. BACKGROUND

[0002] Cashmere is a thin layer of fine hair that grows on the outer skin layer of a goat, covering the root of the coarse hair. Cashmere is a fine and curved fiber that contains a lot of air and forms an air layer, which can prevent the invasion of cold air from outside and keep the body temperature from decreasing. Cashmere is much finer than wool, and the outer scale is also more fine and smooth than wool, so it is light in weight, soft and flexible. Cashmere is a rare special animal fiber and a precious textile raw material. However, due to the presence of a regular thin scale layer on the surface of cashmere compared with ordinary fine wool, cashmere is more prone to felting during machine washing, and the finished product is prone to shrinkage and deformation, affecting wearability. Therefore, the existing expensive cashmere fabric is not convenient for frequent water washing for cleaning, otherwise it will cause shrinkage and deformation, poor bulkiness, and easy to be hard. At the same time, the fiber prepared from cashmere as a raw material, the fabric woven from it, like other fiber fabrics, also has the problem of skin dryness and lack of water when used for a long time, affecting the comfort of use.

[0003] Hyaluronic acid, as an acidic mucopolysaccharide, is a biological molecule naturally existing in the human body, which has excellent moisturizing, lubricating and antibacterial properties. Hyaluronic acid has very good water retention ability, 1 gram of hyaluronic acid can absorb 500 milliliters of water. Because hyaluronic acid can absorb a large amount of water, and has high water retention in any climate, environment and on any skin, it is used in fabrics, which has a beneficial effect on human skin when people wear clothes made of the fabric.

[0004] Currently, there are several methods for applying hyaluronic acid to fabrics: 1. adding hyaluronic acid components to the spinning solution to produce hyaluronic acid fibers, and then spinning the fibers into fabrics; 2. dipping the fiber yarn obtained by spinning in a solution prepared from hyaluronic acid, and then using the fiber yarn to produce fabrics; 3. soaking the fabric woven from fibers in a hyaluronic acid finishing solution, and fixing the hyaluronic acid on the fabric by cross-linking and solidification. Among them, the first method is mainly used for producing synthetic fibers or regenerated fibers by spinning method, and is not suitable for processing natural raw material fibers. The fiber yarn used in the second method and the fabric used in the third method have poor absorption effect of hyaluronic acid, and the moisture retention effect of the finished clothes is not durable, or the hyaluronic acid is easy to fall off after the fabric is washed for many times.

[0031] The application also provides a hyaluronic acid cashmere yarn prepared by the process, and the yarn is made into a fabric suitable for direct skin use.

[0032] The hyaluronic acid cashmere spinning process provided by the application is further described below in combination with examples.

[0033] Example 1

[0034] A hyaluronic acid cashmere spinning process comprises:

[0035] In step 1, the raw material and the wool are mixed and treated by a hyaluronic acid solution to obtain a fibrous substance.

[0036] Step 1 comprises:

[0037] Step 1.1, opening: the selected dyed cashmere is used as a raw material and is unpacked;

[0038] Step 1.2, impurity removal: impurities attached to the raw material are removed;

[0039] Step 1.3, mixing: according to the requirements of different properties of the fabric, different chemical fiber short fibers are selected, and they are uniformly mixed with the cashmere obtained in step 1.2 by using a carding machine, and after dust removal, they are used;

[0040] The addition amount of the chemical fiber short fiber is 0-20% of the total amount of the cashmere mixed raw material by mass percentage;

[0041] BC262 advanced carding machine is used, which is composed of multiple machines connected by pipes between each machine, and realizes multi-functional separation and uniformity of cashmere raw material in sequence, and after multi-bin mixing, impurities are removed, and after high-efficiency dust removal, it is used.

[0042] Step 1.4, hyaluronic acid dissolution: configure a hyaluronic acid solution, uniformly spray it on the cashmere mixed raw material treated by opening in step 1.3 and stand still, control the moisture regain, and obtain fibrous material.

[0043] The addition of hyaluronic acid in the carding stage is based on the high hygroscopicity and dehumidification of cashmere fibers, which can more effectively improve the absorption degree.

[0044] Preferably, a hyaluronic acid raw material with a mass concentration of 5% (i.e., containing 5 wt% of hyaluronic acid) is used, and 3 times of pure water with a temperature of 30°C is added, and after mixing, it is slowly stirred uniformly to promote the dissolution of hyaluronic acid.

[0045] Among them, hyaluronic acid with good quality, high purity and uniform molecular weight distribution is used, which is a material with good thermal stability and is not easily destroyed at normal temperature. In summer, 30-degree water is selected to dilute it, which will not destroy its material structure. In neutral temperature and environment, cashmere has more stable absorption of hyaluronic acid.

[0046] More preferably, the hyaluronic acid raw material uses TASTEX HYALU 04 type product, which contains not only hyaluronic acid with a mass concentration of 5%, but also deep sea fish oil, marine collagen peptide, undecylenic acid monoglyceride and other ingredients, including cationic surfactant.

[0047] Then cool to room temperature, put into the spray mechanical equipment, uniformly spray in the opening treated cashmere mixed raw material, and then stand still at room temperature of 22-25°C for more than 24 hours, turn the bin twice during the period, and the neutral environment is more conducive to the stability of the raw material absorbing hyaluronic acid.

[0048] The moisture regain of the raw material on the machine is controlled to be 28%. The moisture regain of the raw material on the machine is designed to be 28%, which is theoretically based on the comprehensive calculation of the humidity of the raw material, air temperature, room temperature, spinning speed and other comprehensive factors, but in actual operation, it can be appropriately adjusted up and down according to experience, the purpose is to ensure the stability of humidity in the production process, and appropriate humidifying equipment and process are used to ensure the moisture regain.

[0049] Finally, through the chemical reaction of hyaluronic acid, the fibrous material is obtained. Compared with normal cashmere finished yarn, the cashmere raw material and the spun finished yarn added with hyaluronic acid solution have better softness, gloss and elasticity.

[0050] Step 2, the fiber raw material obtained in step 1 is evenly combed by carding to obtain roving fibers, and then a plurality of uniform wool rolls are formed.

[0051] Preferably, the cashmere mixed raw material after absorbing the hyaluronic acid is evenly fed into the carding machine, and the roving sliver is obtained after carding. Among them, the octir advanced carding machine in Italy is used for four times of carding to obtain the effect of uniform carding.

[0052] The cashmere mixed raw material is subjected to four times of carding by the carding machine, and the roving fibers are obtained, and the defects and short fibers are removed in the carding process. Then, the roving fibers are mixed, and the roving fibers are gradually formed into a web and then divided into a plurality of rovings. Finally, the number of rovings is selected according to the process requirement, and a plurality of uniform wool rolls are formed according to the process requirement.

[0053] Step 3, the wool roll obtained in step 2 is evenly pulled, and the twist is added to be wound on the bobbin, and the single yarn is tested. Among them, the B6 frame machine in Italy is used to obtain stable spinning quality.

[0054] Preferably, a plurality of wool rolls with uniform length are placed on the frame machine, the preferred process count is set, the sliver on the wool roll is lengthened and thinned according to the process requirement by the stretching roller at a uniform speed, and the process count requirement is reached; the preferred twist is set, the roving is given the twist required by the process by the rotation of the spindle at a uniform speed, so that the yarn has certain strength, elasticity and gloss; then the spun yarn meeting the count requirement and the set twist is wound on the bobbin, so that the yarn has certain strength, elasticity and gloss; finally, the single yarn is tested.

[0055] The single yarn test includes the use of YG086C yarn length measuring machine for testing and controlling the count of the spun yarn, the use of YC020 electronic single and double yarn strength machine for testing the strength and elongation of the spun yarn, and the use of YG155A yarn twist tester for testing the twist of the yarn to determine whether the twist of the obtained yarn meets the process requirement.

[0056] When testing the strength and elongation of the spun yarn, the tensile strength index of the spun yarn is greater than or equal to 130 CN, and the elongation index is greater than or equal to 8%.

[0057] Step 4, the yarn obtained in step 3 is subjected to after-spinning to obtain yarn products. A plurality of machine types are used in the after-spinning to process the products

[0058] This step 4 comprises:

[0059] Step 4.1, cone: using SAVIO Italy advanced imported equipment. By

[0060] Machine yarn to increase the volume of yarn, improve the efficiency of subsequent processes, and remove defects, impurities, improve yarn quality and strength;

[0061] Step 4.2, doubling: using domestic advanced doubling machine.

[0062] Through the doubling machine, two yarns are quickly and evenly combined into double strands to ensure uniformity, while removing short fibers and defects, and then performing yarn length setting;

[0063] Step 4.3, doubling: using advanced Sura doubling machine of compact TWister.

[0064] Through the twisting movement, winding movement, and yarn guide movement of the doubling machine, the effects of each movement on the entire twisting process are obtained to meet the doubling parameter requirements of the double yarn process, while controlling appropriate temperature and humidity and maintaining uniform speed to obtain high-quality yarn quality.
