Abstract

The present invention relates to a process of a vegetable dye to dye purified cotton knitting fabric, in particular belongs to the textile technical field. The present invention is characterized in that the purified cotton knitting fabric biological enzyme scouring pre-treatment is as follows: the purified cotton knitting fabric is washed with hot water and cold water after being scoured; the subsequent mordant dyeing treatment is as follows: mordant dyeing and vegetable dyeing are performed for the purified cotton knitting fabric after being treated through the biological enzyme scouring; the purified cotton knitting fabric is batched or packed through cold water washing, hot water washing, drying, conventional pre-shrinking and constant breadth. The present invention uses the biological enzyme scouring pre-treatment purified cotton knitting fabric, thus effectively ensuring the subsequent dyeing, improving the stability of the color uniformity and the product quality of the final products, and laying a foundation for the subsequent mordant purified cotton knitting fabric; the vegetable dyeing performance and the quality of the purified cotton knitting fabric after being dyed are improved, for example, the dye absorption rate is improved, the dyeing uniformity and the dyeing stability are improved, and the damage of the purified cotton knitting fabric is reduced.

Description

technical field [0001] The invention relates to a process for dyeing pure cotton knitted fabrics with vegetable dyes, and specifically belongs to the technical field of textiles. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, they have gradually realized that chemically synthesized dyes will cause serious damage and damage to human health and the environment, and plant dyeing has been mentioned again. Ecological textiles is a term that has only appeared in recent years. It refers to textiles that do not produce or contain any substances that may cause harm to human health and have adverse effects on the human environment during the entire process of production, consumption and disposal. The use and development space of synthetic dyes is becoming more and more limited. From the perspective of ecological standards, the dyeing of plant dyes has incomparable advantages over synthetic dyes. However, dyeing w...
