Dyeing technique of true silk-tencel/cotton interwoven cloth

Abstract

The invention provides a dyeing technique of true silk-tencel / cotton interwoven cloth, which comprises the steps of pretreating, dyeing and finishing. The dye liquor used in the dyeing technique comprises 0-5% (owf.) of Lanasol dye, 0-5% (owf.) of Novacron, 1-5 g / L of leveling agent, 15-45 g / L of glauber salt and 5-15 g / L of sodium carbonate. By adopting reactive dyes in different structures, theinvention solves the problem of interaction between true silk and tencel / cotton in the apposition dyeing treatment, and prevents the true silk and tencel / cotton from dyeing each other. In addition, by using the invention, the dyeing technique and color are easy to control and implement, thereby sufficiently displaying the design style, color and pattern effects of the fabric, highlighting the multicolor stereoscopic effect of the high-grade true silk-tencel / cotton interwoven cloth, enhancing the novelty, and satisfying the dyeing and finishing matched technique demands and market demands for novel shell fabric.

Description

Technical field [0001] The invention relates to textile printing and dyeing, in particular to a dyeing process of silk and tencel or cotton interwoven fabric. Background technique [0002] Since ancient times, real silk has been known as the "Queen of Silk". In modern times, people have given it the reputation of "healthy fiber" and "healthy fiber". Therefore, the health function of real silk fiber is incomparable and irreplaceable for any fiber. Silk fiber is a protein fiber and contains 18 kinds of amino acids necessary for the human body, which is almost the same as the amino acids contained in human skin. Therefore, it is also called the "second skin" of human beings. Silk fiber not only has better heat dissipation performance, but also good warmth retention. It also has defense against harmful gas intrusion, resistance to harmful bacteria, and can also enhance the vitality of skin cells on the body, promote skin cell metabolism, and have a good auxiliary treatment effect...

AI Technical Summary

Problems solved by technology

However, due to the difference in the properties of each fiber, the difficulty of printing and dyeing mainly includes the following points: (1) In the pretreatment step, the cotton fiber needs to be treated under alkaline conditions, and it needs to be processed under relatively high alkaline conditions. Satisfactory pretreatment effect is obtained; real silk is not alkali-resistant, and the treatment under strong alkaline conditions will cause the damage of real silk fibers to drop sharply, the gloss is not good, and the hand feeling is affected; the alkali resistance of tencel fibers is between the two Among them, if the alkalinity is too strong, it will not only affect the strength, but also the feel of Tencel fibers will become hard, and fibrillation will occur, losing its proper style; (2) In the dyeing process, cotton fibers or Tencel fiber needs to be dyed under alkaline conditions; while real silk fiber is suitable for dyeing under acidic conditions, the selection and process of dyes also have specific requirements

[0006] The traditional acidic or reactive over-dyeing dyeing process is difficult to achieve the effect of differential dyeing; the dyeing process of one-bath multi-step method or two-bath multi-step method has the defects of long process flow, large consumption of water, electricity, steam, labor and equipment, and is not suitable Energy saving and environmental protection; while using reactive dyes for one-bath dyeing in alkaline conditions, the mutual contamination is serious and the color is difficult to control
