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 particularly relates to a dyeing method of a bamboo fiber fabric based on a mahonia bealei plant dye. When mahonia bealei, used as a natural plant dye, is applied to the bamboo fiber for dyeing, a fabric with the antibacterial property can be obtained to be more applicable to manufacturing of home clothes. The dyeing methodprovided by the invention comprises the following steps of carrying out desizing and scouring treatment on the fabric by adopting starch biological enzyme and scouring enzyme respectively, and performing bleaching by using hydrogen peroxide and hydrogen peroxide biological enzyme; and obtaining a mahonia bealei dyeing solution through alcohol extraction, carrying out dyeing by taking a salt as aco-dyeing agent, and then carrying out soaping. The color of the dyed fabric is soft and elegant, the dyeing process is simple, the mahonia bealei dye obtained through the alcohol extraction mode canbe freeze-dried and stored, and transport and use are facilitated. The scheme is applied to practical production and has high 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 broadleaf dyes. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] Since the 1990s, my country's textile and garment production and export volume has ranked first in the world. While bringing economic and people's livelihood development, the pollution problem of the textile industry cannot be underestimated. Globally, after the oil industry, the textile and apparel industry has become the second largest polluting industry in the world. The traditional textile industry consumes a lot of water, and the pr...
