Abstract

The invention discloses a dust-free pure black processing method for polyester-cotton blend/cotton knitted shell fabrics, and aims to improve yarn structures, a dyeing process and dyeing technology and provides an overall solution to solve the problems that the fibers are damaged to a certain extent, and the down dust falls off and cannot be completely removed by general dyeing devices, and the black fabric is especially serious, after down erosion (bio-enzyme treatment) of the polyester-cotton blend/cotton knitted shell fabrics. The processing method comprises the following steps: singeing ofgrey cloth, presetting, scouring, dyeing, washing and drying, and finalizing of the finished product. Raw materials of vortex spinning cotton yarns and the like are selected for yarns, and a mechanical singeing process is replaced by a bio-enzymatic etching process; the formula of a black monoazo disperse dye SFN, a stabilizer EL-SF and other assistant are used in dyeing polyester fibers, and dyeing cotton uses a super black M reactive dye G 300%. After the dyeing and finishing process, the color fastness indexes are excellent, the dust is very clean, the white color is not stained, and the cloth surface is smooth and clear in lines.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, in particular to a dust-free pure black processing method for polyester / cotton knitted fabrics. Background technique [0002] Polyester-cotton (cotton content over 50%) / cotton knitted fabrics will be treated with hair removal (biological enzyme treatment) during dyeing and finishing production in order to maintain the gloss and texture clarity of the fabric surface, and to feel crisp and skinny. However, after hair erosion treatment, the fibers are damaged to a certain extent, and the hair dust falls off, which cannot be completely removed by cleaning with general dyeing equipment. When the garment is washed, the hair dust is scrubbed out again and floats in the water, giving people the impression of an unsightly appearance with insufficient color fastness. Especially black, the darker the color, the more "dirty" the effect. In the dyeing and finishing industry, it is more c...
