Problems solved by technology

The traditional textile industry consumes a lot of water, and the production process is accompanied by a large amount of wastewater. The production wastewater discharged by printing and dyeing enterprises contains a large amount of fibers, pulp, oils, dyes, and chemical auxiliaries, which is highly harmful and difficult to deal with.
In addition, toxic dyes or processing aids in the production process will also adhere to the fabric, causing a direct impact on human health, such as azo dyes, formaldehyde, fluorescent whitening agents and softeners are allergenic; polyvinyl alcohol and Polypropylene slurry is not easy to biodegrade; chlorine bleaching agent is seriously polluted; some aromatic amine dyes are carcinogenic; dyes contain harmful heavy metals; various finishing agents and printing and dyeing auxiliaries containing formaldehyde are toxic to the human body, etc.
[0004] In addition, in the traditional printing and dyeing technology, alkaline reagents are often used to pretreat the fabric, and these treatments will also have a negative impact on the appearance and use experience of the fabric itself.

Abstract

The invention belongs to the technical field of fabric dyeing methods, and in particular relates to a dyeing method of bamboo fiber fabrics based on broad-leaved ten major meritorious plant dyes. Ten merits as natural plant dyes, dyeing bamboo fiber fabrics can obtain fabrics with antibacterial properties, which are more suitable for the production of home clothing. The dyeing method provided by the present invention includes the following steps: desizing and scouring the fabric by using starch biological enzyme and scouring enzyme respectively, bleaching by hydrogen peroxide and hydrogen peroxide biological enzyme; obtaining the ten merit dyeing liquid by alcohol extraction, using salt Dyeing as dyeing aid, followed by soaping. The color of the fabric dyed by this method is soft and elegant, and the dyeing process is simple. The top ten meritorious dyes obtained through alcohol extraction can be stored after freeze-drying, which is convenient for transportation and use; the application of this scheme in actual production has good economic significance.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing methods, and in particular relates to a method for dyeing bamboo fiber fabrics by using broad-leaved top ten merit dyes. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Since the 1990s, my country's textile and garment production and export volume have ranked first in the world. While bringing economic and people's livelihood development, the pollution problem of the textile industry should not be underestimated. Globally, the textile and garment industry has become the second largest polluting industry in the world after the petroleum industry. The traditional textile industry consumes ...
