Problems solved by technology

[0004] The main component of bamboo fiber is cellulose, but it contains a hollow structure inside, and has the characteristics of high crystallization and high orientation structure. Compared with cotton fiber, bamboo fiber has poor hand feeling and drape, and is easy to wrinkle. Therefore, targeted research is needed on the dyeing process of bamboo fiber fabrics, and there are not many studies on the direct dyeing of bamboo fiber fabrics with grape-extracted dyes, so research on the dyeing of bamboo fiber fabrics with grape pigments is not possible especially necessary

Abstract

The invention provides bamboo pulp fiber fabric based on grape pigment dyeing and a preparation method thereof. The preparation method comprises the following steps of: washing fresh grape skin and grape seeds to dry in air, freezing and grinding the fresh grape skin and grape seeds by use of liquid nitrogen, filtering and screening to obtain powder raw materials, putting the powder raw materials into a supercritical carbon dioxide device to extract, thereby obtaining grape pigments; adding the grape pigments into deionized water, adding a silk fibroin aqueous solution, uniformly stirring, and adding sodium dodecyl benzene sulfonate to obtain grape pigment dye; boiling off and bleaching bamboo pulp fiber fabric, soaking the bamboo pulp fiber fabric in an oxidant solution to carry out activation treatment, taking out, spin-drying, putting the bamboo pulp fiber fabric into the grape pigment dye to directly dye, adding rare-earth elements to fix color, continuously dyeing, taking out the bamboo pulp fiber fabric to carry out soaping, washing, drying and sizing, thereby obtaining the bamboo pulp fiber fabric based on grape pigment dyeing.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a bamboo fiber fabric dyed based on grape pigment and a preparation method thereof. Background technique [0002] Grape pigment is a natural pigment, which belongs to anthocyanin compounds. The main components include mallowin, paeoniflorin, delphinidin, delphinidin, anthocyanin, etc. Grape skin and grape seeds not only contain pigments, but also Contains polyphenols antibacterial, anti-oxidant, skin-friendly and other effective ingredients, so the grape pigment extracted from grapes can not only be used for fabric dyeing, but also can give fabrics a variety of new functions. [0003] Chinese patent CN 101476248A discloses a method for dyeing natural grape seed dyeing extracts on textiles. The textile blanks are subjected to scouring enzyme pretreatment and bleaching treatment, and then the prepared dyeing composition is heated to dye the textiles. Dyeing i...
