Waterproof treatment technology for washing fabric containing bluish dogbane and cotton fibers

Abstract

The invention discloses a waterproof treatment technology for washing a fabric containing bluish dogbane and cotton fibers. The waterproof treatment technology comprises the following steps: A, preparing materials, pre-treating twill, fading, dyeing, coating and washing with an enzyme: 1) an enzyme treatment phase: adding a combined test sample and a weight-gaining testing fabric into an industrial washing machine or a constant-temperature water-bath pot; adjusting the bath ratio and pH (Potential of Hydrogen) value; after washing is balanced, adding a certain amount of the enzyme and then carrying out heat insulation for 20 to 30min; 2) carrying out inactivation treatment: adding sodium carbonate into an enzyme treatment solution and adjusting the pH value to 8 to 10; then raising the temperature to 75 to 100 DEG C; carrying out the heat insulation for half an hour or more, so as to obtain the product. According to the fabric containing the bluish dogbane fibers and the cotton fibers,pure natural washing-fading technological requirements, requirements on temperature of fabric coating glue and requirements on speeds are integrated, so that the coated fabric is more stable, moderate in fastness and easy to control; and a pure natural effect is generated after washing and fading.

Description

technical field [0001] The patent of the invention relates to a fabric, in particular to a water-repellent treatment process for fabrics containing apocynum and cotton fibers. Background technique [0002] Apocynum cellulose has the reputation of "the king of wild fibers". As early as 300 years ago, it was used by the working people in Yili, Ruoqiang and other places. They weave clothes or make quilts and bed sheets, saying that they can cure diseases and keep fit. It is said that apocynum stems are used to make the thatch of thatched huts, because it is not moldy and insect-free; the main component of cotton fiber is cellulose, which is a natural polymer compound. The chemical structure of cellulose is repeated by α-glucose as the basic structural unit. Composition, its element composition is carbon 44.44%, hydrogen 6.17%, oxygen 49.39%. The degree of polymerization of cotton fiber is between 6000 and 11000. In addition, about 5% of other substances are attached to cotto...

Problems solved by technology

After degreasing treatment, the hygroscopicity of raw cotton is increased, and the water absorption capacity can reach 23~24 times of its own weight; therefore, the two kinds of fibers are widely used now, and coating failure often occurs in the existing process of coating mixed fabrics for these two fibers If the effect is not good, it will affect the effect of fading, and the result is either too strong or easy to wash off, so we need a new type of nylon scraping and washing fabric to solve the above problems and meet people's needs
