After-treatment technology of jean fabric

Abstract

The invention provides an after-treatment technology of a jean fabric. The technology comprises the following steps of 1, singeing, wherein a singeing machine is adopted for performing singeing on thejean fabric; 2, desizing, wherein a desizing machine is adopted for removing a sizing agent on the jean fabric; 3, washing, wherein a washing machine is adopted for washing the jean fabric obtained in step 2; 4, scouring, wherein a treatment solution in the step of scouring is a water solution containing 4-6 g / L of a scouring enzyme, the treatment time is 50-55 min, and the treatment temperatureis 95-98 DEG C; 5, drying, wherein a drying machine is adopted for drying the jean fabric; 6, waterproof treatment, wherein surface coating treatment, drying treatment and baking treatment are performed on the jean fabric inside a coating machine in sequence. The scouring enzyme is applied for executing the step of scouring, the sizing agent on the surface of yarn and waxiness, pectin, neps and the like in fiber can be removed, no influence is generated on the fiber body, the moisture absorption effect of the fiber is improved, and therefore the moisture absorption effect of the fabric is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of denim fabrics, in particular to a post-treatment process of denim fabrics. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's pursuit of clothing in life is getting higher and higher, and the requirements for the style, style, and comfort of clothing are getting higher and higher, so they are competitive in the clothing market. Intensifying, constantly innovating and transforming to meet people's needs. [0003] After more than 100 years of development, denim clothing has not changed much in style design. It has always stood in an irreplaceable position in the clothing market because of the varied finishing processes. Different finishing processes endow clothing with different styles. , so that denim clothing has always maintained a certain degree of competitiveness in the clothing market. Tradition...

Problems solved by technology

Although the functional yarn is used to make the fabric have functions, which has the effect of energy saving and environmental protection to a certain extent, but this kind of fiber itself has some functions, but some functional effects are not obvious and cannot meet the requirements, and then the finishing coating makes the fabric It is functional, such as antibacterial, which belongs to dissolution, which makes the antibacterial effect very obvious. For waterproof fabrics, fabrics made of water-repellent fibers will limit the composition of fabrics, so that water-repellent fabrics do not meet the requirements of changing styles. , can not meet people's demand for unlimited fabric components, so waterproof fabrics generally use the method of post-finishing coating to coat the surface of the fabric with a layer of waterproof substances, but denim fabrics are closely interwoven through warp and weft yarns, and after finishing singeing— Desizing-drying-waterproof treatment (coating), when the waterproof test is carried out on the fabric, the test waterproof result does not meet the requirements, so the existing technology needs to be improved
