Method for manufacturing wrapped twisted yarns with spandex wrapped by silk

Abstract

The invention discloses a method for manufacturing wrapped twisted yarns with spandex wrapped by silk, and belongs to the field of technologies for processing textile yarns. The method includes mulberry color yarn processing, doubling, wrapping and twisting and wrapped twisted yarn setting and precision spooling. Mulberry color yarn processing includes carrying out whitening and post-whitening dyeing on 23dtex mulberry yarns f2 S 300 and then carrying out reeling on the 23dtex mulberry yarns f2 S 300 to obtain 23dtex mulberry color yarns f2 S 300. Doubling includes doubling on the mulberry color yarns and 50D vinylon filament yarns in an untwisted manner under the condition of 19CN tension to obtain untwisted doubled yarns. Wrapping and twisting include winding the untwisted doubled yarns on the surfaces of the 20D spandex by the aid of 12CN wrapping tension, controlling drafting quantities of the 20D spandex and twisting the untwisted doubled yarns and the 20D spandex to obtain wrapped twisted yarns with the density of 1750 twists / meter. Wrapped twisted yarn setting includes setting the wrapped twisted yarns by means of dry blowing for 30 min at the dry blowing setting temperature of 60 DEG C. Precision spooling includes spooling the wrapped twisted yarns under the condition of 16CN tension after the wrapped twisted yarns are set by means of dry blowing, and returning cheese yarns after the wrapped twisted yarns are completely spooled. The method has the advantages that the method is high in feasibility and efficiency, and yarn dyeing requirements on elastic silk fabrics can be met by the wrapped twisted yarns manufactured by the aid of the method.

Description

【Technical field】 [0001] The invention relates to a production method for wrapping twisted yarns of silk wrapping spandex, and belongs to the technical field of textile yarn processing. 【Background technique】 [0002] 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. [0003] 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. [0004] Yet the latitudinal real silk elastic fabric of prior art ...

AI Technical Summary

Problems solved by technology

[0005] 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

[0006] The production of silk yarn-dyed elastic fabric has no report in domestic and foreign relevant magazines, professional journals, materials. ) production method, which has not yet been developed
