Problems solved by technology

These existing processes generally have the following problems: 1. Fabrics that are softened by adding softeners will become harder after washing, and they are not energy-saving and environmentally friendly; 2. Softness is achieved through napping 3. Fabrics with soft effects achieved by other finishing processes (mercerizing, liquid ammonia, etc.) More expensive, but also not energy-efficient and environmentally friendly

Abstract

A manufacturing method of all-cotton non-additive soft knitted fabrics comprises the following steps: cotton material selection, yarn spinning process and weaving process. The yarn spinning process conducts first-class fine-staple cotton through the processes of opening, carding, combing, drawing, roving and spinning. Reduce the twist coefficient of the thick and spun yarn process. The twisting direction of the roving process is Z twist, the speed of the flyer is 800-1200r / min, and the total draft ratio is 39-52 times. In the spinning process, the twist direction is S, the reverse yarn knotting method is used, the cop weight is 40‑60g, the flyer speed is 16000‑20000r / min, and the total draft ratio is 39‑52 times. The weaving process selects the bag-like air layer weaving process. Using the above-mentioned manufacturing method of the present application, without adding softener or other softening treatment, a fabric with a soft hand and silk-like luster, that is, a soft knitted fabric with no added cotton, can be obtained.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for manufacturing an all-cotton additive-free soft knitted fabric. Background technique [0002] At present, there are a wide variety of cotton fabrics on the market, with various styles and handles. The main methods to make the hand feel soft are: 1. Adding softener, 2. Fleece finishing, 3. Other finishing processes. These existing processes generally have the following problems: 1. Fabrics that are softened by adding softeners will become harder after washing, and they are not energy-saving and environmentally friendly; 2. Softness is achieved through napping 3. Fabrics with soft effects achieved by other finishing processes (mercerizing, liquid ammonia, etc.) More expensive, but also not energy-saving and environmentally friendly. Contents of the invention [0003] The invention provides a method for manufacturing all-cotton non-additive soft knitted fabrics, the...
