Description
Technical Field
The invention relates to the technical field of dyeing, in particular to a dyeing method of silk peptide modified cotton fabric by utilizing coptis dye.
Background
In the textile industry, the use of dyes and the development of dyeing techniques have made textile garments more elegant and loved. Since the advent of synthetic dyes in the 19 th century, synthetic dyes have been rapidly developed in the twentieth century by virtue of their full chromatograms, bright colors, fastness to washing, fastness to sunlight, mass production, low price, etc., and have become the main colorants for textiles, gradually replacing natural dyes, and becoming the most important colorants for textiles. However, the synthetic dyes bring great pollution to the environment in the industrial production process, seriously destroy the ecological balance, and have certain influence on the human health. The natural dye is non-toxic and harmless, has no anaphylaxis and carcinogenicity to skin, and many of the plant dyes are Chinese herbal medicines, and have unique medicinal health care function to human body. Because most textile fabrics are in direct contact with human bodies, the natural dye has wide development prospects in the fields of high-grade silk products, health-care underwear, home textile products, decorative articles and the like. If the drug effect function of the dye plant and the dyeing function of the dye plant can be combined and applied to the development of textile fabrics, green and environment-friendly textiles which are popular with people and have the health-care and medicinal effects can be developed.
The coptis chinensis is a famous Chinese herbal medicine, the main effective component berberine of the coptis chinensis belongs to quaternary ammonium alkaloids, and is also used as a main pigment source of dye, the potential value of the coptis chinensis dye in the aspect of dyeing is fully developed, the natural dye coptis chinensis is applied to dyeing of cotton products, the added value of the cotton products is improved, meanwhile, the full naturalization of the cotton products can be realized, the requirements of people in the new century on the cotton products are met, and the coptis chinensis is also a good way for developing 'ecological cotton textiles' and 'full green cotton textiles'. The dyeing effect of the coptis chinensis dye on cotton fabrics is improved through modification treatment on the cotton fabrics, and the environment-friendly natural dye of the coptis chinensis can be widely applied to dyeing of textiles, so that healthier, environment-friendly and green textiles can be obtained.
The coptis chinensis dye has dyeing property and antibacterial property, and is very worthy of development. As the only natural cationic dye, the coptis has better dyeing effect on protein fibers, for example, the coptis extract has good dyeing effect on wool fabrics and silk fabrics, and obtains brighter yellow, but has lower dye-uptake on cellulose fibers such as cotton. The cotton fabric is soft in hand feeling, comfortable to wear and low in price, is the fabric which is most popular and used by people, but because the affinity of the cotton fiber and the golden thread dye is not enough, the golden thread has poor dyeing effect on the cotton fabric, the dye-uptake is low, the color is not bright, and the color fastness is not high. In order to improve these defects, a dyeing method of silk peptide modified cotton fabric using coptis chinensis dye is needed, which modifies cotton plants to improve the dyeing performance of coptis chinensis.

Detailed Description
The following examples may assist those skilled in the art in a more complete understanding of the present invention, but are not intended to limit the invention in any way.
Example 1:
a method for dyeing silk peptide modified cotton fabric by using coptis dye comprises the following raw materials: oxidizing agent, silk peptide solution and cotton fabric.
The method comprises the following steps:
(1) preparing raw cloth: the preparation of the raw cloth comprises raw cloth inspection, cloth turning (batching, boxing and printing) and head sewing, wherein the purpose of the raw cloth inspection is to inspect the quality of the grey cloth, and the problem can be solved in time when the problem is discovered. The inspection content comprises two items of physical indexes and appearance defects;
(2) singeing: the singeing aims at burning off the fluff on the cloth cover, so that the cloth cover is smooth and beautiful, and uneven dyeing and printing defects caused by the fluff during dyeing and printing are prevented;
(3) desizing: firstly, sodium periodate is used for carrying out oxidation treatment on the cotton fabric, so that silk peptide can be smoothly attached to the surface of the cotton fabric, and the silk peptide modification of the cotton fabric is realized; the effect of silk peptide modification is influenced by the concentration of an oxidant and the concentration of silk peptide, and when a single condition is changed, the weight gain rate of cotton cloth is higher along with the increase of the concentration of the oxidant; the rate of weight gain increases with increasing silk peptide concentration; however, too large a concentration of the oxidizing agent will seriously affect the mechanical properties of the fabric, so that the concentration of the oxidizing agent should not exceed 2 g/L.
(4) Dyeing: after the silk peptide modified cotton fabric is dyed by the coptis dye liquor, the dye uptake is obviously improved compared with the untreated cotton fabric, and the color is more yellow and bright. The silk peptide concentration and the dyeing temperature influence the dye uptake of the fabric to coptis chinensis, and when a single condition is changed, the dye uptake gradually rises along with the increase of the silk peptide concentration; the dye uptake rate gradually decreased with increasing treatment temperature. After the cotton fabric is subjected to silk peptide modification treatment, the soaping color fastness of the dyed fabric is improved to a certain extent compared with that of untreated cotton fabric. But the colorfastness to washing is still lower and still needs to be further enhanced.
Wherein, the oxidant and the silk peptide solution are respectively provided with three different concentration specifications; the oxidant is used in combination with enzyme desizing and alkali desizing; bleaching the cotton fabric after the step (3), wherein any one of a sodium nitrilate method, a hydrogen peroxide method and a sodium chlorite method can be selected; and (4) slowly raising the temperature of the high-temperature cylinder in the step (4), wherein the highest temperature cannot exceed 130 ℃, and the temperature is reduced to below 85 ℃.
The golden thread dye has good dyeing effect on silk fabrics, the scheme adopts silk peptide to pretreat cotton fabrics, sodium periodate is firstly used for oxidizing cotton fabrics, and then oxidized cotton fabrics react with silk peptide solution, so that a large amount of active groups such as amino, hydroxyl and the like are deposited and fixed on cotton fibers, the dyeability of natural dyes is improved, meanwhile, the excellent performances of silk, such as improvement of hygroscopicity, hand feeling, suspension style and the like, are given to the cotton fabrics, and the prepared natural dye dyed cotton fabrics have elegant and natural tone, unique style and good market prospect.
