Ecological antioxidants for improving light oxidation resistance of natural dye dyed fiber products

Abstract

The invention relates to an ecological antioxidant for improving the photooxidation resistance of a natural dye dyed fiber product. The antioxidant comprises superoxide dismutase, and also comprises one or more of trehalose, deoxidize enzyme, lipoic acid and chlorogenic acid, the antioxidant concretely includes superoxide dismutase, chlorogenic acid and lipoic acid according to a mass ratio of (1-5):(1-5):(1-5). The antioxidant is mainly used for post-treating the natural dye dyed fiber product to make the fabric related fastness improved. The antioxidant has the advantages of high efficiency,environmental protection, greenness, non-toxicity, good durability and the like, a treatment method has the advantages of low cost, simplicity, convenience, good operability and the like, and the antioxidant and the treatment method lay a foundation for the improvement of the wearability of the natural dye dyed fiber product, and solve the problem of oxidative fading of a natural dye.

Description

technical field [0001] The invention relates to an ecological antioxidant method for fiber products, in particular to an ecological antioxidant for improving the photooxidative resistance of natural dye dyed fiber products. Background technique [0002] Under the action of light, the dyes on fiber products often undergo photoreduction or photooxidation reactions, and sometimes even act together in the beginning and end of the dye photofading process, which is an important cause of dye photofading. Affected by the structure of natural dyes, it is more prone to photoreduction and photooxidation reactions, thus resulting in low color fastness of fabrics dyed with natural dyes, which limits the further development of natural dyes, and the related problems of oxidative fading of natural dyes have not been resolved. Effective solution to defects in fabric swatches dyed with natural dyes. [0003] In order to solve the problem of light fading of natural dyes on fiber products, a l...

Problems solved by technology

Affected by the structure of natural dyes, it is more prone to photoreduction and photooxidation reactions, thus resulting in low color fastness of fabrics dyed with natural dyes, which limits the further development of natural dyes, and the related problems of oxidative fading of natural dyes have not been resolved. Effective solution to defects in fabric swatches dyed with natural dyes

[0006] Although the above-mentioned additives for improving the photostability and oxidation of dyes have certain effects, they obviously do not match the ecological characteristics of natural dyes.
