Novel burnt-out knitted fabric and preparation method thereof

Abstract

The invention discloses a novel burnt-out knitted fabric and a preparation method thereof. The fabric is prepared by processing a burnt-out grey fabric; the warp yarns of the burnt-out grey fabric areformed by blending siro compact spinning yarns and polyester fibers, and weft yarns of the burnt-out grey fabric are core-spun yarns formed by blending spandex with bamboo fibers and polyester blended yarns. The siro compact spinning yarns are adopted as the raw material of the fabric, and meanwhile, the spandex is added, so that a good burning effect can be achieved, the bursting strength and compactness of the fabric surface can be guaranteed, and the fabric has good elasticity.

Description

technical field

[0001] The invention relates to the technical field of textile fabrics, in particular to a novel burn-out knitted fabric and a preparation method thereof. Background technique

[0002] With the continuous development of the economy and the gradual improvement of living standards, consumers' consumption concepts of knitted clothing have undergone great changes. In addition to basic functions such as warmth and comfort, they also seek the exquisite appearance and antibacterial properties of fabrics. Function. Jacquard fabrics are loved by consumers due to their exquisite appearance, but knitted jacquard fabrics on the market have problems such as low production capacity, high prices, and unsatisfactory jacquard details; The problem of fiber loss after washing has greatly limited the market's recognition of the two fabrics.

[0024] The preparation method of the above-mentioned burned-out knitted fabric comprises the following steps:

[0025] Step S1, alkali treatment: put the burnt fabric into a vat filled with a sodium hydroxide solution with a concentration of 20-30 g / L, undergo an alkali treatment at a temperature of 80-100°C for 40-80 minutes, and then wash it with water. neutralize;

[0026] Step S2, burn-out treatment: dye the burnt-out gray cloth treated with alkali through an overflow tank by double-bath dyeing method; use a flat screen printing process to scrape-print the burnt-out gray fabric on the dyed burnt-out gray cloth, Bake at a temperature of 110-120°C for 5-8 minutes until it is completely carbonized, then wash with water at a temperature of 40-50°C for 30-60 minutes, and finally dry to obtain the fabric.

[0027] As a preferred embodiment, in step S2, the water washing adopts a combination process of open-width water washing machine cleaning and in-cylinder cleaning, and biolo...
