Production method of woolen light and thin cashmere fabric

Abstract

The invention discloses a method for producing woolen light and thin cashmere fabrics. The technological process includes the following steps in sequence: selecting raw material fiber → blending wool → surface PVA → carding roving → spun yarn → de-PVA → winding → weaving → finishing → obtaining Woolen light and thin cashmere fabric; wherein, the selection of raw material fiber process selects cashmere fibers, including cashmere long fibers; the surface PVA process includes drying the cashmere long fibers after the wool treatment in PVA solution; the de-PVA process It is PVA on the surface of the yarn after washing with water to remove the spun yarn. The invention breaks through the limitations of woolen spinning, introduces long cashmere fibers into woolen spinning, and makes cashmere long fibers fully exert the advantages of reinforcing yarns by hardening cashmere fibers, and obtains fluffy, light and soft cashmere fabrics through the woolen spinning method, and the process is environmentally friendly and efficient. It saves time and effort, and the source of raw materials is more abundant.

Description

technical field [0001] The invention relates to a production method of fabric, in particular to a production method of woolen light and thin cashmere fabric. Background technique [0002] As a high-grade fiber, cashmere is favored by consumers for its light weight, smooth feel, soft luster, plump suede, and excellent warmth retention. According to different thicknesses, it is suitable for wearing in spring, autumn and winter. The darling of the fabric market, the wearing season of cashmere fabrics has also expanded from winter to spring and summer, and the weight requirements of cashmere fabrics have also been extended to 250-300g / m 2 Light and light fabric category. The overall trend is that the demand for cashmere products in domestic and foreign markets is becoming increasingly thinner, softer and more comfortable. [0003] However, due to the fineness and low strength of cashmere fibers, the slubbing process has not been combed and spun into yarns. The yarn spun has th...

Problems solved by technology

However, most of the raw materials used in this method are short cashmere fibers. Even if long cashmere fibers are used, the long cashmere fibers lack carding, and the curls and turns in the fabric are mostly maintained, and the potential of the long cashmere fibers to enhance the yarn strength cannot be exerted.

After the water-soluble fiber is washed off, although the cashmere sweater has a certain bulkiness and lightness, the main component of the yarn and fabric is cashmere staple fiber or cashmere long fiber in a curled state, and the yarn strength is low and the count is still high. , the light and thin effect of the fabric is quite different from the worsted effect

[0005] In view of the shortcomings of time-consuming, labor-intensive and cashmere fiber raw material consumption in the production of light and thin cashmere fabrics by worsted spinning, and the technical problems that woolen spinning is difficult to obtain light and thin cashmere fabrics, how to develop high-quality woolen light and thin cashmere fabrics is very important.
