Embodiment 1

[0023] A method for dyeing bamboo fiber yarn with low salt and alkali, comprising the following steps:

[0024] A, pretreatment: adopt enzyme refining liquid to carry out biorefining treatment to bamboo fiber yarn, then deactivate enzyme at high temperature, take out and dry;

[0025] B. Preparation of dye solution: Add natural plant dyes into the dye bucket, add sodium sulfate and glacial acetic acid in proportion, inject water to make a solution, and add an environmental dyeing accelerator to prepare a biological dye solution;

[0026] C. Dyeing: inject the prepared biological dye solution into the dyeing barrel, raise the temperature to 62°C, and add the pretreated yarn for dyeing;

[0027] D. Post-treatment: After taking out the dyed yarn, soap it with 98.5°C soap solution for 12 minutes, wash it with cold water, fix it with 118°C high-temperature steam for 3.5 minutes, and then wash it with cold water;

[0028] E. Take out the yarn and dry it at 48°C.

Abstract

Disclosed is a method for dyeing low-salt and low-alkali bamboo fiber yarns. The method has the advantages that the bamboo fiber yarns are treated by biological enzymes, the biological enzymes have mild effects on the yarns, and the fiber strength is not reduced too much; through interactive use of corresponding dyestuff, the yarns with good performance indicators such as dye uptake, color fastness and colored light are obtained; a small-bath-rate dyeing process is adopted, so that water consumption is greatly reduced, the fixation rate is increased, salt consumption is reduced, influences ofsewage discharge on soil salinization are reduced, and the dyeing uniformity is high; an environment-friendly dyeing accelerator is used in a dyeing process, the dyeing effect of natural dyestuff canbe improved greatly, and the color fastness of the yarns is improved; according to the method for dyeing the low-salt and low-alkali bamboo fiber yarns, the bamboo fiber yarns obtained through biological enzyme refining liquid treatment, natural dyestuff dyeing, high-temperature soaping and steam fixation treatment have good dyeing effect, tender color and high drapability, and feel soft.

Description

technical field [0001] The invention relates to the technical field of yarn dyeing, in particular to a low-salt and low-alkali bamboo fiber yarn dyeing method. Background technique [0002] Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. It has good air permeability, instant water absorption, strong wear resistance and Good dyeability and other characteristics, with natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions. With unique environmental protection and health care functions, the textiles produced by it just meet the trend of modern people's pursuit of health and comfort. Its natural characteristics determine that it does not need to do connotation carving. On the premise of not destroying its original ecological and healthy elements, it only needs to add some elements in color, weaving and dyeing and design, etc., and it will be ...
