Abstract

The invention discloses a production process of a coriander yarn, which relates to the technical field of silk dyeing and finishing, and comprises the steps of selecting pure silk fabric as a blank, and carrying out modification pretreatment on the blank by adopting a chitosan quaternary ammonium salt solution derived from natural plants; the method comprises the steps of taking dioscorea cirrhosa as a main dyeing raw material, adding four natural primary color auxiliary dyes of sappan wood, pomegranate rind, soap scuttle and Polygonum tinctorium to prepare a multicolor compound dyeing liquid, strictly keeping the process of traditional coriander yarn, replacing the traditional single dioscorea cirrhosa dyeing liquid with the prepared multicolor compound dyeing liquid to dye and mold, drying, shaping, cutting, inspecting and packaging the molded fabric to obtain a multicolor coriander yarn finished product. According to the invention, the natural plant-derived chitosan quaternary ammonium salt is adopted to pretreat the silk blank, and the multicolor compound dyeing liquid is combined, so that the adsorption capacity and dyeing uniformity of the fabric to natural plant pigment can be improved on the premise of keeping the core process of the traditional yarn of the balsam yarn, and the color of the finished product is enriched.

Description

Production process of coumarins yarn Technical Field The invention belongs to the technical field of silk dyeing and finishing, and particularly relates to a production process of a coriander yarn. Background The balsam yarn, the Ben yarn and the Ji yarn silk are the only silk fabrics dyed by pure vegetable dye in world textiles, are also national non-matter cultural heritage and geographical mark protection products, are mainly produced in Guangdong pearl triangle areas, and are commonly called as 'sound cloud yarn' because of sand sound generated during washing and walking. The traditional coriander yarn is made by using pure silk fabric as blank, adopting yam juice for dyeing, and adopting river mud rich in ferrous ions for coating and sealing, and adopting a plurality of procedures of repeated soaking and sun-drying, mud passing, cleaning and the like, and the finished fabric has the characteristics of coolness, comfort, easy washing and quick drying, deep color, dirt resistance, softness, stiffness and durability, also contains natural plant and mineral essence, emits light plant fragrance, has a certain health care effect, and is a representation of natural environment-friendly high-grade silk fabric. However, the traditional coriander yarn production process still has a plurality of technical bottlenecks, and limits market popularization and industrial upgrading, firstly, in the traditional coriander yarn production, silk blanks are not subjected to targeted pretreatment, active sites firmly combined with the dioscorea cirrhosa natural pigment are lacking in a silk fibroin molecular structure, so that the pigment is not uniformly adsorbed and insufficient in penetration depth in the dyeing process, the dyeing efficiency is low, the problems of fading and uneven color are easy to occur, and the quality stability of the product is influenced, secondly, the traditional coriander yarn dyeing only takes the dioscorea cirrhosa as a single dyeing raw material, after being matched with river mud for coating, the color of a finished product is mainly dark brown, black and the classical color of positive and negative heterochromatic, the color is single, the consumption requirement of the small masses can be met, the requirements of the fields such as modern clothing, home and the like on the multi-color system and individuation are not met, the application scene of the products is difficult to attract young consumer groups, and the existing part tries to expand the process of the coriander system, the traditional core process is mostly adopted, the traditional core process is added or changed, the color diversity is realized, the color is not is influenced, the natural color is damaged, the natural quality of the natural yarn is damaged, the natural yarn is the natural color is environment-friendly, and the natural yarn is polluted, and the natural quality is environment-friendly, and natural yarn is caused, and the natural quality is polluted, and the natural quality is caused by the core yarn is simultaneously. The chitosan quaternary ammonium salt is a modified product derived from natural plants, is prepared by quaternizing and modifying chitosan, has excellent water solubility, can be effectively crosslinked with silk fibroin fibers, can improve the dyeing property, antibacterial property and wrinkle resistance of silk fabrics, has little influence on the natural whiteness and handfeel of silk, is an environment-friendly and nontoxic natural modifier, and is very suitable for pretreatment of silk fabrics. The sappan wood, the pomegranate rind, the soap scuttle and the Polygonum tinctorium are all natural plants, the extracts of the sappan wood, the pomegranate rind, the soap scuttle and the Polygonum tinctorium can be used as natural dyes, respectively present four primary colors of red, yellow, black and blue, have good compatibility with the dioscorea cirrhosa dye, do not release harmful substances, can cooperate with the dioscorea cirrhosa pigment to prepare various color systems, and can not destroy the natural properties of the coriander yarns. Therefore, research and development of the traditional natural normal production process of the coumarone yarn can not only keep the essence of the traditional natural normal production process of the coumarone yarn, but also improve the dyeing performance through the pretreatment of natural plants, simultaneously realize multi-color production, and give consideration to environmental protection, practicability and process inheritance, become the technical problem to be solved urgently in the current coumarone yarn industry, and have important significance in promoting the activation and utilization of non-material cultural heritage and promoting the upgrading of the coumarone yarn industry. Disclosure of Invention The invention aims to provide a production process of a coumarone yarn, which is characterized in that a natural plant-derived chitosan quaternary
