Description
Technical Field
The invention relates to the technical field of cashmere spinning, in particular to a spinning process of water-soluble fibers and high count cashmere yarns.
Background
In recent years, the development of textile fabrics has a trend of diversified raw materials, light and thin structure, moist style and functional use. The development of high-count ultrathin fabrics by using the water-soluble fiber and the cashmere/wool also becomes a new application field of the water-soluble PVA fiber. The high-count ultrathin fabric obtained by blending the water-soluble fibers and the cashmere not only has more outstanding elasticity, drapability and bulkiness, but also improves the spinning and weaving efficiency, enables the fabric to be more high-grade, expands the use range of the cashmere, greatly reduces the unit cost of the product, and has wider development prospect and good economic benefit.
At present, the water-soluble fiber mainly used for blending with cashmere is PVA fiber, the Chinese name is polyvinyl alcohol, the water-soluble fiber is completely dissolved in water at 60-70 ℃, is tasteless, nontoxic and colorless transparent aqueous solution, can be naturally and biologically degraded in a short time, and is blended with cashmere fiber, so that the variety of the cashmere yarn is enriched, the defects of low strength and easy breakage of weaving of the cashmere yarn are overcome, the spinnable count of the cashmere yarn is improved, and the spinning difficulty of the cashmere yarn is reduced; the PVA dissolving treatment is carried out in the finishing process after weaving, the knitted product is wholly soaked in the water temperature for about 30 minutes and is rinsed for a plurality of times, and dissolved matters of the PVA are removed. The process mainly utilizes the principle that PVA is dissolved when meeting high temperature to meet the requirements of various indexes of the product.
Although the blended spinning of the cashmere and the water-soluble fiber has the advantages of making the fabric light and thin and the like, the blended spinning of the water-soluble fiber and the cashmere is not widely applied, mainly, when the blended fabric is subjected to after-treatment, the water-soluble fiber is removed by a water washing mode, the yarn evenness of the yarn is much poorer than that of the pure cashmere, even the structure is loosened and broken, and the style and serviceability of the product are reduced. One of the main reasons for the defects is that the water-soluble fibers and the cashmere are not uniformly mixed during blending, the cashmere belongs to natural fibers because the water-soluble fibers are synthetic fibers, and compared with chemical synthetic fibers, the cashmere has stronger moisture absorption capacity and moisture regain of 15-17%, and a scale layer is arranged on the surface of the cashmere, so that the cashmere fibers have hydrophobicity, rough and uneven surface and higher friction coefficient, and the specific directional friction effect of the wool fabric is also given because of the special morphological structure of the scale layer. The water-soluble fiber has smooth surface but weak antistatic ability, and because the thickness and density of the cashmere and the water-soluble fiber are different, mixing is difficult to a certain degree.
On the other hand, when the water-soluble fibers and the cashmere are blended, the PVA accounts for a small proportion, the fibers are thin, the uniform mixing is also difficult, the improvement of the specific gravity of the water-soluble fibers is beneficial to the uniform mixing, but the proportion of the water-soluble fibers is too high, the yarn count after washing can be greatly improved, but the structure can be loosened after the fabric is finished, and the service performance of the product is reduced. Therefore, when the water-soluble fiber and cashmere are blended, the number of blending lanes is generally increased from 3 to 5, and the effect is unstable.
Disclosure of Invention
The invention provides a spinning process of water-soluble fiber and high count cashmere yarn, which can uniformly mix cashmere and water-soluble fiber in a wool mixing stage by improving the spinning process and modifying the water-soluble fiber on the other hand, and can ensure that the sliver is uniform and the wearability of the product is good after the water-soluble fiber is removed by washing.
The invention realizes the purpose through the following technical scheme:
a spinning process of water-soluble fiber and high count cashmere yarn comprises the following steps:
the first step is the mixing of hairs, which are very important links in production. Because the water-soluble fiber is easy to dissolve in water, when the wool is added with water, the water-soluble fiber is not added with water, the oil and water are completely added on the cashmere, and the cashmere is tightly closed for 24 hours or more, so that the oil and water are fully absorbed. After 24 hours, the water soluble fibers are opened and then uniformly mixed with the cashmere.
Before wool blending, oil and water are required to be added to cashmere, and the oil and water have the functions of adjusting static and dynamic friction coefficients between fibers, reducing friction between the fibers and a guide roller, preventing and eliminating static electricity generated by friction in the working procedures of drafting, twisting and the like, improving cohesive force of fiber bundles and the like. So that the wool fiber can smoothly pass through the equipment for carding, spinning and the like, and the phenomena of wool scattering, winding, end breakage and the like are prevented. Therefore, the composition of oil and water is also important for the uniform mixing of the cashmere and the water-soluble fibers, the static and dynamic friction coefficient of the cashmere is reduced, the antistatic capacity is enhanced, and the mixing of the cashmere and the water-soluble fibers is facilitated. In the application, the oil-water composition is obtained by adding 3.5% of wool oil FX-906, 1.5% of antistatic agent FX-AS301 and 12% of water according to the mass percentage of cashmere, and the oil-water composition is obtained by long-term practice in a production workshop and is most beneficial to the mixing ratio of the cashmere and PVA water-soluble fibers.
The wool top FX-906 has good permeability, lubricity, cohesion and antistatic property, and is an ideal auxiliary agent for making strips, carding and spinning by pure cashmere. In the rough and sparse wool spinning, the fly wool can be obviously reduced, the end breakage rate is reduced, the product yield is improved, the spinning strength can be effectively increased, the yarn CV value is reduced, and the wool grain, nubs and details are reduced. In the wool combing sliver making and spinning, the fibers can be tightly cohered, slivering is smooth, the spinning life is obviously improved, and the phenomena of winding leather rollers, rollers and the like are reduced.
In order to further improve the antistatic capacity of cashmere fibers, 1.5 percent of an antistatic agent FX-AS301 is added into oil water, and the FX-AS301 is a special antistatic agent for chemical fiber and cashmere blended yarns, has an excellent antistatic effect, can effectively eliminate fly caused by static electricity in the spinning processing process, enables the yarn production process to be smoothly carried out, and can be matched with nonionic or anionic wool oil for use.
Before use, 3.5 percent of wool oil FX-906 and 1.5 percent of antistatic agent FX-AS301 are weighed according to the weight of cashmere fibers, added into normal-temperature (20 ℃) deionized water or distilled water under stirring, and stirred for 10-15 minutes to form a uniform solution for use. Oil and water are added into the cashmere in a spraying mode, and the wool oil is uniformly sprayed on the cashmere by adjusting the position of a spray head. The sprayer can be arranged on the left side and the right side of the cashmere conveying belt and is vertical to the conveying direction, the cashmere sprays oil and water, sprayed liquid drop particles are refined as much as possible, and the moisture regain of the cashmere on the machine is controlled to be 24-26% through reasonable oil and water spraying.
Adding oil water, tightly closing cashmere for more than 24 hours, and primarily mixing the cashmere and the water-soluble fibers, wherein the primary mixing is realized by paving a layer of cashmere on a flat ground, then paving a layer of water-soluble fibers, and sequentially and alternately paving the cashmere and the water-soluble fibers, and the thinner the cashmere and the water-soluble fibers are, the better the mixing effect is. Cashmere and water-soluble fiber are generally alternately paved into 2-4 layers, and then fed into a wool making machine for fully mixing.
And secondly, processing the mixed material of cashmere and water-soluble fibers into roving by using a carding machine, wherein the humidity of a carding workshop is smaller due to the addition of the water-soluble fibers so as to prevent the fibers from agglomerating to wind a cylinder due to high humidity, but the humidity is not too low, so that the electrostatic phenomenon is serious in the spinning process, the spinning is difficult, and the yarn is dry and uneven in thickness. The temperature of the carding workshop is controlled to be 24-26 ℃, and the humidity is controlled to be 60-65%.
And thirdly, drafting and twisting the rough yarn by using a spinning machine to form spun yarn, winding the spun yarn into yarn ears, controlling the temperature of a carding workshop to be 20-30 ℃, controlling the humidity to be 60-65%, controlling the humidity of the workshop as the same as that of the carding workshop, and keeping the relatively small humidity. Due to the addition of the water-soluble fiber, the yarn strength is increased, the spinnability is improved, and the drafting multiple of the spun yarn can be properly increased and controlled to be 1.30-1.35.
And fourthly, the bobbin winder changes the bobbin of the spun yarn and winds the spun yarn, meanwhile, the thin or thick yarn strips are removed, the doubling machine is used for doubling and plying the single yarn, the two-for-one twister is used for twisting the plied yarn, and the yarn is wound. With reference to the production of pure cashmere yarns, the speed of the vehicle can be properly accelerated due to the improved spinnability. The workshop can not be humidified, the humidity of the workshop is well controlled, and the relatively small humidity is kept.
Specifically, when the water-soluble fibers and the cashmere are mixed, the water-soluble fibers account for 20-30% of the total weight of the blended fibers, the proportion of the water-soluble fibers is too low, the yarn count is improved a little after washing, and the due effect cannot be achieved; the proportion of the water-soluble fiber is too high, the yarn number can be greatly increased after washing, but the structure can be loosened after finishing the fabric, and the wearability of the product is reduced. Therefore, it is very important to select an appropriate blending ratio. Through tests, the proportion of the water-soluble fiber is proper at 20-30%, so that the yarn count can be improved, the strength can be improved, and the wearability of the fabric can be ensured.
Furthermore, the average length of the cashmere is 32-36 mm, the fineness is 15.5-16.0 microns, the short fiber rate is below 15%, the water-soluble fiber is polyvinyl alcohol fiber, the length is 38mm, and the fineness is 1.5D. The length and the thickness of the water-soluble fiber and the cashmere are as close as possible, which is beneficial to more uniform blending. Meanwhile, the length of the cashmere fiber not only affects the quality of the fabric, but also is the basis for determining a spinning system and selecting technological parameters, and the cashmere with the same fineness and the long fiber can be spun into high count yarn. When the number of the spun yarn is fixed, the yarn spun by the long fiber has high strength, good evenness and low yarn breakage rate. The method can obviously improve the quality of the wool fabric, is easy to be controlled by a drafting mechanism in the spinning and drawing process, is not easy to form 'floating fiber', and is not easy to generate yarn defects such as thick and thin wool yarn knots, big belly yarns and the like. Generally, the finer the wool fiber, the smaller the fineness dispersion, the higher the relative strength, and the dense scales, the better the quality of the fiber. In the process of blending the water-soluble fibers and the cashmere, the length of the cashmere is required to be 32-36 mm, the fineness is 15.5-16.0 mu m, and the short fiber rate is below 15%, so that the blended yarn has excellent performance.
In order to further uniformly mix the water-soluble fibers and the cashmere, the water-soluble fibers are modified, the water-soluble fibers are selected as polyvinyl alcohol fibers, and the surfaces of the polyvinyl alcohol fibers are modified in a radiation mode: and (3) soaking the polyvinyl alcohol fiber into the modification solution, radiating for 5-10 min by using UV at the temperature of 30-50 ℃, and filtering and drying to obtain the modified polyvinyl alcohol fiber. The purpose of modification is to make the densities of the water-soluble fiber and cashmere closer, increase the volume of the water-soluble fiber, simultaneously, the dissolving temperature is lower, avoid the damage to the cashmere fiber caused by overhigh water temperature, and make the yarn even and smooth. The components of the modified liquid are as follows: 0.5-1.0% of dispersant CH-10S, 0.1-1.0% of coupling agent KH-550, 1.0-3.0% of cross-linked carboxymethyl starch sodium and 2.0-5.0% of polyacrylamide are added into ethylene glycol.
The cross-linked carboxymethyl starch sodium has good water absorption and water swelling property, after the surface of the PVA water-soluble fiber is cross-linked and modified, the volume of the PVA fiber can be increased, after the cross-linked carboxymethyl starch sodium is mixed with the cashmere fiber, the percentage of the PVA fiber is increased, the smaller the proportion is, and the more difficult the mixing is. When the amount of PVA fiber is increased appropriately, mixing can be made easier.
The PVA fiber product before modification is most contraindicated to be wetted, once wetted, the PVA fiber product can generate fluff blocks and conglomerations, and the quality of the final product is seriously influenced, so the PVA fiber product must be prevented from being wetted in the production process. The temperature and the humidity of a workshop need to be strictly controlled, in the actual production, the cashmere fibers added with oil water still have certain moisture on the surface, and after the PVA and the cashmere are mixed, the PVA absorbs a small amount of moisture, so that the mixing difficulty is increased. The modified PVA can increase the fiber volume after absorbing water, but does not agglomerate, and is easier to mix evenly.
Polyacrylamide is a generic name for acrylamide homopolymers or polymers obtained by copolymerizing acrylamide with other monomers, and is one of the most widely used species in water-soluble polymers. Because the polyacrylamide structural unit contains amide groups and is easy to form hydrogen bonds, the polyacrylamide structural unit has good water solubility and high chemical activity, and various modifiers with branched chains or net structures can be easily obtained through grafting or crosslinking. After the water-soluble PVA fiber is modified by polyacrylamide and crosslinked carboxymethyl starch sodium, the dissolving temperature of the fiber in water can be reduced.
Compared with the prior art, the invention has the beneficial effects that the proportion of the water-soluble fiber and the cashmere and the components and content of oil and water are adjusted by improving the process, the temperature and the humidity of a production workshop are controlled, particularly, the water-soluble fiber and the cashmere are required to be uniformly mixed in the wool blending process, and the fabric with uniform evenness and compact structure is obtained after the water-soluble fiber is removed by washing.
