Problems solved by technology

However, proteolytic enzymes need to be dissolved in water before being added to the training solution, and can be used after dilution. It is a long process to dissolve itself, and it is easy to agglomerate in the training solution, and the bleaching results cannot meet some special requirements of customers.
[0003] To sum up, the traditional scouring process of silk twill can remove most of the natural impurities and artificial impurities in sericin and silk fibroin, but there are still a small amount of pigments, inorganic substances and other impurities deposited on the fibers. Among them, if it is used as white silk, it may be no problem, but when dyeing or printing, impurities such as waxes and pigments on the surface of the fabric will cause color spots and spots on the product, poor dye permeability, and uneven color on both sides of the fabric. occur

Abstract

The invention provides a scouring and bleaching process capable of improving the permeability of silk twill, and belongs to the technical field of spinning scouring and bleaching. The scouring and bleaching process is characterized by comprising the following steps: after immersing a textile with hot water, scouring and bleaching in a scouring solution, wherein the scouring and bleaching temperature is controlled to be 97 DEG C to 98 DEG C, the scouring and bleaching time is 80min to 100min, a bath ratio is 1 to (46 to 54), and the pH (Potential of Hydrogen) is 9 to 10; then scouring and bleaching again in a scouring solution added with hydrogen peroxide, wherein two types of auxiliary agents including 0.17g / L to 0.23g / L of sodium silicate and 2.7g / L to 3.3g / L of the hydrogen peroxide are added for scouring and bleaching in an oxygen bleaching manner, the scouring and bleaching time is 80min to 90min, the pH is 8 to 9, and the bath ratio is 1 to (37 to 43); finally, washing with high-temperature water, washing with warm water, washing with acid and washing with cold water. By adopting the production process provided by the invention, natural impurities and artificial impurities on the textile can be removed, and 99 percent of the impurities can be removed; the defects of color tones, color points, poor permeability of dyestuff, non-uniform coloring and the like during dyeing or printing can be avoided.

Description

technical field [0001] The invention discloses a bleaching process for improving the permeability of real silk twill, belonging to the technical field of textile bleaching. Background technique [0002] There are two main types of traditional scouring techniques: one is the soap-alkali scouring method, in which soap is used as the main scouring agent, and soda ash, sodium silicate, etc. are added to the scouring liquid as auxiliary scouring agents. This method uses soap as the main refining agent, the consumption is very large, the production cost is high, and the impurities and pigments in sericin and silk fibroin cannot be completely removed. The second is the enzyme-soap scouring method, which uses proteolytic enzymes to catalyze the hydrolysis of sericin peptide tendons to achieve the purpose of degumming, and uses soap to remove wax and other sundries. However, proteolytic enzymes need to be dissolved in water before being added to the training solution, and can be use...
