Abstract

The invention, which belongs to the technical field of the textile fabric, provides a method for producing weft-knitting suede fabric. The method comprises the following steps: (1), weaving is carried out; to be specific, weft knitting is carried out on 20% to 26% of T400 high stretch yarn and 74 to 80% of sea-island filaments to form fabric; (2), washing is carried out; (3), splitting is carried out; to be specific, the processed fabric is put into a solution including caustic soda and an M-1100 splitting agent, wherein the bath ratio is 1 to 15-20 and the temperature is 90 to 92 DEG C; (4), singeing is carried out; to be specific, the fabric is processed by flame quickly to burn fuzz formed on the surface of a piece of greige cloth, wherein the flame temperature of the fuzz burning is 900 to 1000 DEG C; (5), dyeing is carried out; (6), drying is carried out; (7), sanding is carried out; and (8), drying and sizing are carried out. The product produced based on the method has advantages of high coverage, soft feeling, high lustrousness and flexibility, substantially improved fabric performance, simple production process, high production efficiency, and low cost.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a production method of weft-knitted suede. Background technique [0002] The surface of suede fabric is dense, slender, soft and thick, with good warmth retention, moisture absorption and slippery touch. It is the first choice material for sofa covers, clothing and artificial leather. Suede fabric has many properties that are not inferior to natural suede, and many properties are even better than natural suede, such as its fabric has soft wool, waxy, good drapability, and light and thin texture. In addition to the above-mentioned advantages, the suede formed by the knitting process also has excellent elasticity and extensibility. At present, the warp-knitted structure is mainly used, and sea-island silk is generally used as raw material. The weaving is completed on a 2-3 comb high-speed machine, and then through It is processed by dyeing, shaping and other processes. Th...
