Abstract

The invention discloses a preparation method of a spun silk/PTT (polytrimethylene terephthalate) blended fabric with a shape memory function. The preparation method is characterized by comprising the following steps: blending PTT short fibers in the blended dry weight ratio of 30 to 70 percent with spun silk fibers to obtain spun silk/PTT blended yarns with the linear density of 83.3 to 166.7 dtex; taking the blended yarns as weft yarns and warp yarns, configuring the density of the warp yarns to be 450 to 600 yarns/10cm, the density of the weft yarns to be 200 to 280 yarns /10cm and the total coverage coefficient of the fabric to be 75+/-3 percent, configuring the number of fabric tissues to be 2 or 4, making fabric gray cloth, and forming finished fabric by refining, four-time washing, drying and shaping. By applying the method provided by the invention, the fabric has high tensile-recovery elasticity, crease recovery,and a shape memory function of shaping, flattening, and smoothening easily, and meanwhile, has the advantages of high moisture permeability, high flexibility, high wear comfort and the like, is a functional spun silk shell fabric, and can serve as the shell fabric of high-end casual clothes.

Description

technical field [0001] The invention relates to a preparation method of spun silk / PTT blended fabric with shape memory function. Background technique [0002] Silk fabric has pearl-like soft luster, soft and smooth to the touch, especially the skin-fitting feeling is incomparable to other fibers. It has good hygroscopicity, good air permeability, good drape and elegant feeling when worn in summer. However, silk fabrics also have certain defects, such as: easy to wrinkle, poor elasticity, easy to shrink, yellowing, etc. In addition, real silk products have a single material, with a single mulberry silk as the main raw material, which has a narrow range of use and short wearing seasons. [0003] Polytrimethylene terephthalate (PTT) fiber has excellent resilience performance, and at the same time has the softness of nylon, the bulkiness of acrylic fiber, and the stain resistance of polyester, so it has a wide range of applications in clothing fabrics. Blending and interweavin...
