Description

Technical Field

[0001] The present application relates to the technical field of cashmere textiles, and in particular to a cashmere loop yarn woven scarf and a production process thereof. Background Art

[0002] With the rapid development of the cashmere industry, cashmere products not only have the unique intrinsic qualities of cashmere fiber such as softness, smoothness, breathability and warmth, but the appearance design has also gradually incorporated some youthful elements from the original simplicity, classic elegance.

[0003] In the traditional production of cashmere scarves, the common practice is to use pure cashmere fibers for weaving or woven, and then perform a series of post-processing to finally form the finished product. However, although scarves woven with pure cashmere fibers using the traditional method feel comfortable, they are monotonous in color and lack expressiveness. Although the use of fancy yarns can increase the richness of the pattern, how to use fancy yarns in cashmere products is currently a technical challenge. Summary of the invention

[0004] In order to improve the color richness and texture of a cashmere scarf, the present application provides a cashmere loop yarn woven scarf and a production process thereof.

[0005] In a first aspect, the present application provides a production process for a cashmere loop yarn woven scarf, which adopts the following technical solution: a production process for a cashmere loop yarn woven scarf, comprising the following specific steps: S1: Cashmere fibers are pre-processed through a combing spinning process of mixing wool-combing-striping-combing-blending-re-combing-gilling-slubbing-spinning to prepare cashmere combed single yarn, and then the cashmere fibers are processed through a process of mixing wool-combing-striping-combing-blending-re-combing-gilling-slubbing to prepare cashmere roving, and the cashmere combed single yarn is used as a core yarn and a solid yarn, and the cashmere roving is used as a decorative yarn, and cashmere loop yarn is produced through a fancy twisting machine; S2: The spun cashmere loop yarn is subjected to anti-pilling finishing using a composite agent, and then subjected to yarn steaming, reeling, and yarn clearing treatments to obtain cashmere brushed yarn, which is then waxed, and the cashmere brushed yarn is woven with mercerized wool in warp and weft to obtain a cashmere loop yarn woven scarf.

[0006] By adopting the above technical scheme, cashmere combed single yarn and cashmere roving with good texture are prepared through the steps of wool mixing, combing, sliver sorting, combing, blending, re-combing, needle combing, roving, spun yarn and the like, and the uniformity, strength and softness of the yarn are improved. Cashmere combed single yarn is used as the core yarn and solid yarn, and cashmere roving is used as the decorative yarn. Cashmere loop yarn is formed by a fancy twisting machine to form a loop yarn with a ring or spiral structure. This structure not only improves the elasticity of the yarn, but also increases the three-dimensional sense and elasticity of the scarf. Using cashmere brushed yarn and mercerized wool for warp and weft weaving can enhance the color richness and three-dimensional sense of the product, and can also improve the structural stability and durability of the scarf. Anti-pilling finishing of cashmere loop yarn in advance can reduce the pilling phenomenon in the subsequent weaving and finishing process, and then the yarn is shaped by steam treatment, so that the anti-pilling effect is more stable and lasting, and rewinding and yarn cleaning can remove impurities in the yarn. Waxing can form a protective layer on the yarn surface to improve the smoothness and antistatic properties of the yarn.

[0007] Preferably, the wool fiber is cashmere fiber with a fineness of 12-15 μm and a length of 35-40 mm.

[0008] Preferably, the waxing amount of the cashmere brushed yarn is 1-2.5 g / kg cashmere brushed yarn.

[0009] Preferably, the composite agent includes protease, chitosan, and polyvinyl alcohol, and the anti-pilling finishing method includes the following specific steps: pre-impregnating the cashmere loop yarn with protease at 40-50°C, then washing it with water at room temperature and then impregnating it with chitosan at 50-60°C, then washing it with water at room temperature and then impregnating it with polyvinyl alcohol, and drying it to complete the anti-pilling finishing of the cashmere loop yarn.

[0010] By adopting the above technical scheme, the cashmere loop yarn is first treated with protease, which can pre-break the peptide bonds of the cashmere fiber scale layer with protease to generate more active groups, which is beneficial to the adsorption and film-forming reaction of chitosan. Chitosan forms a thin film on the surface of the cashmere fiber, which can prevent the mutual bite of adjacent fiber scales, and weaken the fiber directional friction effect, which is beneficial to improve the anti-pilling performance and hand feel of the cashmere loop yarn. After chitosan finishing, polyvinyl alcohol finishing can be used to form a denser protective film on the surface of the cashmere loop yarn fiber by utilizing the moldability and adhesion of polyvinyl alcohol, which makes the film-forming effect of chitosan on the surface of the cashmere loop yarn fiber more stable, and provides double protection for the cashmere loop yarn fiber, thereby enhancing the anti-pilling performance of the cashmere loop yarn and improving the hand feel and gloss of the cashmere loop yarn.

[0011] Preferably, the cashmere loop yarn after anti-pilling treatment is extruded through roller holes, and then subjected to yarn steaming, yarn rewinding and yarn clearing treatments to obtain cashmere brushed yarn.

[0012] By adopting the above technical scheme, after the cashmere loop yarn after anti-pilling treatment is squeezed through the circular hole of the roller, the excess compounding agent can be squeezed out, so that the loop part of the cashmere loop yarn is close to the core wire, the compactness of the cashmere loop yarn is increased, the yarn structure is tighter, and the gaps between fibers are reduced, thereby improving the strength and stability of the yarn.

[0013] Preferably, the prepared cashmere loop yarn woven scarf is fluffy and soft finished with a fluffy softener, wherein the fluffy softener comprises linear block polyether amino silicone oil, acrylate resin and antistatic agent, and the mass ratio of the linear block polyether amino silicone oil, acrylate resin and antistatic agent is 2: (0.8-1.2): (0.05-0.15).

[0014] By adopting the above technical scheme, the linear block polyether amino silicone oil can fix the polysiloxane segment on the fabric surface through the hydrogen bonding between the amino group and the imino group and the fiber, and the polyether segment is adsorbed on the fiber surface, which can improve the softness and fluffiness of the scarf. The acrylic resin forms a thin film on the surface of the scarf fiber. The film has a certain elasticity and can increase the space between the fibers to make the scarf fluffier. The acrylic resin film can reduce the friction between the fibers, making the fibers smoother, thereby improving the softness of the scarf. The antistatic agent can improve the slipperiness of the scarf, making the fibers smoother and reducing friction.

[0015] Preferably, the preparation method of the linear block polyether amino silicone oil comprises the following specific steps: The double-terminal amino polyether, double-terminal epoxy polyether silicone oil and isopropyl alcohol are mixed, and under the protection of nitrogen, the temperature is raised to 75-85° C. and reacted for 7-9 hours to obtain a linear block polyether amino silicone oil.

[0016] Preferably, the cashmere loop yarn woven scarf is immersed in a fluffy softener treatment solution, centrifugally dehydrated, microwave treated, and dried to complete the fluffy and soft finishing of the cashmere loop yarn woven scarf.

[0017] In a second aspect, the present application provides a cashmere loop yarn woven scarf, which adopts the following technical solution: A cashmere loop yarn woven scarf is produced by the production process.

[0018] In summary, this application has the following beneficial effects: 1. In the production process of cashmere loop yarn woven scarf, the cashmere combed single yarn is used as the core yarn and the solid yarn, the cashmere roving is used as the decorative yarn, and the cashmere loop yarn is formed by a fancy twisting machine to form a loop yarn with a ring or spiral structure, thereby improving the elasticity of the yarn and enhancing the three-dimensional sense and elasticity of the scarf. The cashmere loop yarn is firstly subjected to anti-pilling finishing, and then subjected to steam treatment to shape the yarn, so that the anti-pilling effect is more stable and lasting.

[0019] 2. In the present application, protease, chitosan and polyvinyl alcohol are used in sequence to perform anti-pilling finishing on the cashmere loop yarn, forming a dense and stable protective film on the surface of the cashmere loop yarn fiber, preventing the mutual bite of adjacent fiber scales, causing the fiber directional friction effect to weaken, and improving the anti-pilling performance of the cashmere loop yarn.
