Processing method of double-component elastic spandex core-spun yarn

Abstract

The invention discloses a processing method of a double-component elastic spandex core-spun yarn, comprising raw materials, production steps and production process improvement thereof, wherein the raw materials include a first elastic spandex filament, a second elastic spandex filament and wrapping yarn; the second elastic spandex filament is half of the first elastic spandex filament in diameter, and the two elastic spandex filaments differ in traction multiple; and the wrapping yarn is a short fiber; the production steps include: rolling the comparatively thick wrapping yarn into the form of a flat strip; before entering into a spinning room, guiding both the elastic spandex filaments as double cores to the middle of the flat-strip shaped wrapping yarn; folding the flat-strip shaped wrapping yarn by taking the double cores as a fold line, and covering the double cores on the fold line in the flat-strip shaped wrapping yarn; feeding the double cores and the folded flat-strip-shaped wrapping yarn into the spinning room, and stretching and twisting in an 8-shaped form to form the double-component elastic spandex core-spun yarn. The product is elastic and free from the feeling of being too tight on the body, and overcomes the shortcoming of being insufficient in elasticity or too tight.

Description

technical field [0001] The invention relates to a production process of a core-spun yarn, in particular discloses a processing method of a two-component elastic spandex core-spun yarn. Background technique [0002] The elasticity of the traditional elastic spandex core-spun yarn depends on the thickness of the elastic spandex in the yarn and the stretching ratio of the spandex. Small, so when the spandex core-spun yarn produced is made into clothing, the clothing produced by the yarn with high elasticity will give people a sense of discomfort due to the strong force of the body when wearing it. Clothes produced by thread, because the elasticity is too small, can not reflect the elastic effect, and the curve of the body cannot be displayed. Therefore, developing a kind of clothing material that has certain elasticity and is not too tight, and has a strong sense of comfort, and caters to the needs of consumers has become the common goal of the textile industry.

[0002] The elasticity of the traditional elastic spandex core-spun yarn depends on the thickness of the elastic spandex in the yarn and the stretching ratio of the spandex. Small, so when the spandex core-spun yarn produced is made into clothing, the clothing produced by the yarn with high elasticity will give people a sense of discomfort due to the large force of the body when wearing it. Clothes produced by thread, because the elasticity is too small, can not reflect the elastic effect, and the curve of the body cannot be displayed
