Problems solved by technology

[0005] The disadvantage of the prior art is that, in today's environment-friendly environment, the use of a large amount of acid and alkali chemical reagents will not only destroy the ecological environment, but also be harmful to the health of the human body after remaining on the fiber.
The disadvantage of this invention is that strong alkali reagents such as sodium hydroxide are used, which is not environmentally friendly and unfavorable to human health

Abstract

The invention relates to the technical field of pre-spinning processing techniques of textile fibers and discloses a production method of linen carded slivers for linen / cotton blending. The production method includes the steps of A, covering linen second hards, and spraying ecological emulsifier during stowing; B, subjecting the linen second hards to forced opening after stowing so as to obtain rough linen; C, subjecting the rough linen to secondary stowing; D, subjecting the rough linen, subjected to secondary stowing, to fine carding to obtain fine linen; E, subjecting the fine linen to tertiary stowing; and F, subjecting the fine linen, subjected to tertiary stowing, to blowing and carding to obtain the linen carded slivers. The ecological emulsifier comprises, by weight, 2% to 5% of plant fat, 2% to 5% of pectinase, 2% to 3% of surfactant, 1% to 2% of salt, and 85% to 95% of water. The novel ecological emulsifier contains no strong acid and alkali chemicals and is green and harmless; the linen carded slivers produced by the production method have little chemical residue, low impurity content and good spinnability.

Description

technical field [0001] The invention relates to the technical field of textile fiber pre-spinning treatment technology, in particular to a method for preparing flax wool sliver used for blending cotton and linen. Background technique [0002] In today's world, the enthusiasm of human beings to pursue green and ecological environmental protection continues to rise. In the production of traditional textiles, a large number of chemical products such as sizing materials, bleaching dyes, and finishing agents are used, which cause serious pollution to the environment and bring hidden dangers to human health. Therefore, green and eco-friendly textiles have become a high-level pursuit of consumers. [0003] Hemp fiber has good moisture absorption and air permeability, low static electricity and antibacterial properties, but its elasticity and wear resistance are poor, so it usually needs to be blended with other fibers to make fabrics. Flax is one of the main hemp fibers. The surfa...
