Abstract

The invention belongs to the field of textile technologies and particularly relates to a preparation method of cationic spandex single jersey knitted fabric. The fabric is composed of 25 wt% of dacron, 70 wt% of acrylic fibers and 5 wt% of spandex. The preparation process includes the steps of yarn forming and fabric pre-treatment. A dyestuff additive used in the fabric pre-treatment process comprises, 0.1-0.3 wt% of cationic blue BG-ED, 0.05-0.10% of cationic red GRL-ED, 0.12-0.25 wt% of cationic yellow 3RL-ED, 0.8-1.3 wt% of glacial acetic acid, 1.5-3.5 wt% of anhydrous sodium sulphate, 0.8-1.5 wt% of ammonium sulfate and the balance water. After the twist of yarn in the fabric yarn forming process is controlled and special dyeing and finishing are conducted, the fabric has the stereoscopic feeling, and a cloth cover is active, not rigid, smooth in hand feeling, good in drooping feeling, breathable and capable of absorbing moisture and releasing sweat. The fabric is easy to dry after being washed, not prone to wrinkling, free of deformation and suitable for being used as summer coat garment materials.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a cationic spandex jersey knitted fabric. Background technique [0002] Knitted fabrics are fabrics formed by bending yarns into loops with knitting needles and interlocking them. The difference between knitted fabrics and woven fabrics is the shape of the yarn in the fabric. Knitting is divided into weft knitting and warp knitting. At present, knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are loved by consumers. Heather gray fabric is comfortable to wear, absorbs sweat and dries easily, making it a good fabric for summer tops. Yet common hemp ash cloth after dyeing, the three-dimensional effect of cloth surface effect is not strong, more rigid, has limited its development. Contents of the invention [0003] The object of the present invention is to provide a preparation method of cat...
