Wrapped twisted yarn with silk wrapped spandex

Abstract

The invention discloses a wrapping twisted yarn for wrapping spandex with real silk, which belongs to the technical field of textile yarns. It is composed of face silk and spandex core wire. The face wire is wrapped around the surface of the spandex core wire with a fineness of 7.4D. The face wire is made of mulberry silk and 50D vinylon filament under the condition of 19CN of yarn tension. Untwisted mulberry silk, mulberry colored silk is 23dtex mulberry colored silk f2 S 300, which is made of 23dtex mulberry silk f2 S 300 after refining, dyeing and forming into a tube. For the wrapping and twisting of the spandex core yarn, the wrapping and twisting yarns discharged from the wrapping yarn machine are set by dry steaming to form a wrapping and twisting yarn structure of 1750 twists / m. By adopting the above-mentioned technology, the wrapping and twisting thread has strong implementability and high production efficiency, and can satisfy the yarn-dyed weaving of silk elastic fabrics.

Description

[0001] 【Technical field】 [0002] The invention relates to a wrapping twisted yarn of real silk wrapping spandex, which belongs to the technical field of textile yarns. [0003] 【Background technique】 [0004] Along with the changes in the concepts and eyesight of consumers and the improvement of consumption levels, the elastic varieties of yarn-dyed fabrics have been vigorously promoted, leading people to pursue the consumption of comfortable and multi-colored clothing and apparel fabrics. [0005] Silk elastic fabrics are suitable for high-grade clothing fabrics, such as pajamas, shirts, sportswear, and swimwear fabrics. It solves the phenomenon of suture slippage during use, that is, the phenomenon of suture tearing, and overcomes the problem of ordinary clothing in the process of wearing and exercising. The tight feeling in the fabric makes it easy and comfortable to wear, so it is easy to take. [0006] Yet the latitudinal real silk elastic fabric of prior art stage is on...

Problems solved by technology

[0007] The warp thread is made of mulberry silk, and the weft thread is a covered thread made of undegummed mulberry silk and spandex core silk. The silk elastic fabric obtained by weaving is degummed and then dyed to obtain a plain silk (commonly known as a glance) elastic fabric. Because of its pure color, it cannot satisfy people's desire for rich colors in silk elastic fabrics, thus limiting the quality of silk fabrics. Wide application of elastic fabric

[0008] The production of silk yarn-dyed elastic fabrics has not been reported in relevant magazines, professional journals, and materials at home and abroad. Before the present invention was made, the used color weft for the production of silk yarn-dyed elastic fabrics is the wrapping of silk-wrapped spandex. Twisted thread, no one has developed it yet
