Abstract

The invention discloses a production method of cotton-like knitted fabric. The production method includes the steps of 1, making all-biomass polyester chips from, by weight, 9-8 parts of 1, 2-propanediol, 3-5 parts of 1, 2-butanediol, 4-6 parts of pentanediol, 2-4 parts of sorbitol, 3-5 parts of ethanediol, 16 parts of bio-base 1, 3-propanediol, and 1 part of bio-base 2, 5-furan diacid; 2, subjecting the all-biomass polyester chips to melt spinning at the spinning temperature of 310DE C, at the spinning speed of 1550m/min, at the drawing temperature of 90DEG C, under the pre-drawing ratio of 1.5, under the primary drawing ratio of 4-5, and under the secondary drawing ratio of 2-3, so as to obtain all-biomass polyester fiber; 3, knitting warps and wefts containing the all-biomass polyester fiber into the cotton-like knitted fabric. The knitted fabric produced by the production is more compatible with the human body and meets the requirements for health and environment protection.

Description

technical field [0001] The invention relates to a preparation method of a cotton-like knitted fabric. Background technique [0002] The knitted fabrics currently on the market are not very compatible with the human body. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a cotton-like knitted fabric, which has better compatibility with the human body and meets the requirements of health and environmental protection. [0004] In order to achieve the above object, the technical solution of the present invention is to design a method for preparing a cotton-like knitted fabric, comprising the following steps: [0005] 1) Take 8-9 parts by mass of 1,2-propanediol, 3-5 parts by mass of 1,2-butanediol, 4-6 parts by mass of pentanediol, 2-4 parts by mass of sorbitol, and 3-5 parts by mass of ethyl alcohol Diol, 16 parts by mass of bio-based 1,3-propanediol, and 1 part by mass of bio-based 2,5-furandic acid are used to pre...
