Problems solved by technology

[0006] It can be seen from the above-mentioned patents that the fabrics are all scoured and bleached, which can be carried out at a lower temperature, but they are directly scoured and bleached on the fabrics, and the quality of the scoured and bleached process is the key factor for the quality of the fabrics, because In the process of boiling and bleaching, if the bleaching is too light, the impurities will not be removed completely, and the amount of knots will be large, and they will be hidden in the spun yarn. powerful
Moreover, due to the uneven fiber thickness of the roving itself, it will become more uneven after being boiled and bleached, resulting in irreversible unevenness in the spun yarn, and frequent end breaks during spinning, which directly affects the feel of the final hemp fabric and powerful
Because the hemp fiber has more crystallization regions than ordinary natural fibers, it is difficult for some additives to penetrate into the fiber. However, the above-mentioned patent does not pre-treat and modify the hemp fiber, resulting in a smaller specific surface area of ​​the fiber. Subsequent treatment of the fiber The adsorption effect of additives is poor, resulting in tighter and stiffer fabrics, poor drape, and poor hand feeling

Abstract

The invention relates to the technical field of textile production technologies, in particular to a production process of a modified China hemp high count yarn fabric based on biochemical degumming. The production process includes the following steps of (1) biochemical modification of rough yarn; (2) singeing treatment; (3) low-temperature oxygen bleaching pre-finishing; (4) dyeing; (5) finishingby means of a microemulsion finishing technology, wherein finishing includes (1) pre-finishing, (2) microemulsion finishing, (3) rolling and cold stacking, (4) water washing and neutralization, (5) biological enzyme polishing and (6) drying. In a microemulsion finishing process, a microemulsion can permeate into non-crystalline areas in spun yarn fibers of a fabric during cold stacking and make the spun yarn fibers open, so that the fibers are more fluffy and softer, the fabric drape factor is better, the fabric is smoother and finer in hand feeling, the water-washed appearance of the fabric can reach the 3-4 level of the GB / T22700-2008 standard, and the high-end clothing functionality needs are met. A treatment process is simple, treatment conditions are mild, the production process is environmentally friendly, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of textile production technology, in particular to a production technology based on biochemical degumming modified hemp high-count yarn fabric. Background technique [0002] Hemp, also known as thread hemp, cold hemp, hemp, etc., has more than ten kinds of aliases. According to historical records, hemp originated in China, and hemp was the first natural fiber used by humans in fabrics. As a green and environmentally friendly ecological fiber, hemp fabrics not only have natural antibacterial, ultraviolet radiation shielding, moisture absorption and perspiration, softness and comfort, skin care and cleaning, odor absorption and wear resistance, but also have noble, elegant, unpretentious, natural and practical styles. Therefore, hemp fabrics are increasingly popular with people. Hemp fiber exists in the hemp husk. In addition to cellulose, the hemp husk also has associated impurities such as hemicellulose, p...
