Nylon washed fabric with scraping color

Abstract

The invention discloses a nylon washed fabric with scraping color. The preparing method of the fabric comprises the steps of material preparation, pretreatment of twill cloth, fading dyeing, dyeing, coating and enzyme washing. The process of enzyme washing comprises the steps of an enzyme treatment stage, wherein composite samples and weight increment test accompanying fabric are put into an industrial washing machine or a constant temperature water bath kettle, the bath ratio and pH value are adjusted, after washing balance is achieved, a certain amount of enzyme is added, and then heat preservation is conducted for 20 minutes; inactivation treatment, wherein sodium carbonate is added into an enzyme treatment liquid, the PH value is adjusted to 9-10, then the temperature is increased to 85 DEG C or more, and heat preservation is conducted for a period. According to the technological requirements of the pure natural wash-fading style of the chemical fiber fabric, the glue, temperature and speed of fabric coating are required to be three-in-one, so that the coated fabric is more stable, the fastness is moderate, the fabric is easy to control, and the fabric has the pure natural effect after being faded by washing.

Description

technical field [0001] The invention belongs to the technical field of fabric production, and in particular relates to nylon color-scraping and washing fabrics. Background technique [0002] Nylon was developed by an outstanding scientist in the United States, Carothers, and a research team under his leadership. It is the first synthetic fiber to appear in the world. Polyamide commonly known as nylon, English name, density 1.15g / cm 3 , is the general term for thermoplastic resins containing repeating amide groups—[NHCO]—on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its naming depends on the specific number of carbon atoms in the synthetic monomer. Polyamide is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher th...

Problems solved by technology

However, the heat resistance and light resistance of polyamide fiber are poor, and the retention is not good, and the clothes made of it are not as crisp as polyester

In addition, both nylon-66 and nylon-6 used for clothing have the disadvantages of poor hygroscopicity and dyeability. For this reason, a new type of polyamide fiber-new polyamide fiber of nylon-3 and nylon-4 has been developed. Lightweight, excellent wrinkle resistance, good air permeability, good durability, dyeability and heat setting, etc., so it is considered to be very promising, and it is often used in the coating process of existing nylon scraping and washing fabrics The effect of the coating is not good and affects the effect of fading. It is either too strong or easy to wash off. Therefore, we need a new type of nylon scraping and washing fabric to solve the above problems and meet people's needs.
