Yellow lyocell fabric prepared by dyeing with blakeslea trispora fermentation extract and preparation method thereof

Abstract

The invention relates to a yellow lyocell fabric prepared by dyeing with a blakeslea trispora fermentation extract and a preparation method thereof. The method comprises the following steps of fermenting blakeslea trispora, culturing and purifying to obtain beta-carotenoid; and preparing a phenol oxidase solution and a cellulase solution, preparing a dyeing solution from the beta-carotenoid, the phenol oxidase solution, the cellulase solution, an H2O2 solution and the like, putting manganese dioxide, a lyocell fabric and a dyeing solution into a dyeing machine for dyeing, performing enzyme deactivation on the dyed lyocell fabric, washing with tap water, and drying to obtain the yellow lyocell fabric. According to the yellow lyocell fabric prepared by dyeing with the blakeslea trispora fermentation extract and the preparation method thereof provided by the invention, cellulose and the beta-carotenoid are respectively activated by selecting cellulase and polyphenol oxidase, so that graft polymerization reaction of the cellulose and the beta-carotenoid is realized. The dyeing conditions are mild, so that the pollution to the environment is small; and the dyed yellow lyocell fabric has a relatively high K / S value, and the soaping fastness and the dry rubbing fastness grade are relatively high.

Description

technical field

[0001] The invention belongs to the technical field of fabric preparation, and in particular relates to a yellow lyocell fabric obtained by dyeing a fermented extract of B. trispora and a preparation method thereof. Background technique

[0002] As early as thousands of years ago, people knew how to obtain colors from plants to decorate their clothing. They squeeze sap from the plants and use it for dyeing or drawing designs. The well-known henna and bluegrass are common dye plants. There are also records about plant dyes in many ancient books. For example, "Shuowen Jiezi" in the Eastern Han Dynasty recorded 39 names about plant colors. In the Tang Dynasty, the dyeing process developed rapidly, and color even became a symbol of class status. With the development of opening up to the outside world such as the Silk Road, China's printing and dyeing technology has been widely spread to countries in West Asia, which has had a profound impact on world printing ...
