Embodiment 1

[0035] The production method of spandex core-spun elastic fabric includes cotton, polyester and spandex. The warp direction is a blended yarn formed by 16 cotton fibers and bamboo fibers. The cotton fiber content is 60%, and the bamboo fiber content is 40%; It is 150D low-elastic network yarn and 70D spandex covered yarn. The dyeing process includes the steps of turning cloth, single-sided singeing, scouring and bleaching, setting, mercerizing, dispersive hot-melt dyeing and finishing.

[0036] Among them, the blended yarn formed by cotton fiber and bamboo fiber is treated with bamboo vinegar. The bamboo vinegar treatment includes the first bamboo vinegar treatment and the second bamboo vinegar treatment. The first bamboo vinegar treatment is to immerse the blended yarn at 65°C. In the first bamboo vinegar treatment solution for 12 minutes, the second bamboo vinegar treatment is to immerse the blended yarn in the second bamboo vinegar treatment solution at 88°C for 5 minutes. The ...

Abstract

The invention relates to a textile and in particular relates to a production method of a spandex core-spun elastic fabric. The spandex core-spun elastic fabric comprises cotton, polyester and spandex, blended yarns formed by sixteen cotton fibers and bamboo fibers are arranged in warp direction, the content of the cotton fibers is 50%-70%, the content of the bamboo fibers is 30%-50%, and 150D low-elasticity network yarns and 70D covered spandex are arranged in weft direction. A dyeing process comprises the steps of turning cloth, singeing of a single side, scouring and bleaching, sizing, mercerizing, disperse hot melting dyeing and after finishing; the singeing of the single side is concretely singeing by a gas, singeing is carried out twice on the front of two fire holes, and a processing speed is 80-85 m / min; the blended yarns formed by the cotton fibers and the bamboo fibers are subjected to bamboo vinegar treatment, and the bamboo vinegar treatment comprises primary bamboo vinegar treatment and secondary bamboo vinegar treatment, wherein the primary bamboo vinegar treatment comprises the step that the blended yarns are immersed in a first bamboo vinegar treating fluid at the temperature of 60-70 DEG C for 10-15 minutes, and the secondary bamboo vinegar treatment comprises the step that the blended yarns are immersed in a secondary bamboo vinegar treating fluid at the temperature of 85-90 DEG C for 3-8 minutes. The spandex core-spun elastic fabric product is stable in dimension after being washed, does not need to be ironed and is high in antibacterial rate.

Description

Technical field [0001] The invention relates to a textile, in particular to a method for producing a spandex core-spun elastic fabric. Background technique [0002] The application of elastic fabrics in clothing provides comfort, casualness and beauty that shows the shape of the human body, and is deeply loved by consumers.
