With the development of the market, the era when conventional denim dominated the world has long passed. Now denim of various colors is competing for favor. The traditional denim is dyed with indigo, and the color is relatively deep. In order to meet the needs of all aspects, old-fashioned denim is also It has been loved by more and more people. Usually, a certain washing process can be used to achieve a certain effect of aging. However, at present, various washing processes for aging are uneven, and improper selection of various process conditions can easily lead to aging. Problems such as uneven effect or reduced strength of denim fabric or easy fading
On the market, the denim fabric with old visual effect fades unevenly, and only the surface of the denim fabric fades, and the physical damage of the denim fiber can also be seen, and the price is high

Abstract
A processing method for making denim show an old visual effect, which is characterized by comprising the following steps: (1) desizing and softening the denim; (2) dehydrating the denim, and then placing it in a washing machine; (3) ) Washing and enzyme treatment of denim; (3) Cleaning of denim after washing and enzyme treatment; (4) Whiskering of denim after washing; (5) Stitching of denim after whiskering (6) After the abrasion treatment, the denim is washed, dehydrated, dried, ironed and shaped, and rack-baked to obtain the finished denim. The resulting denim has a real sense of aging and little damage to the overall fabric.
Description
technical field [0001] The invention relates to a processing method for making denim fabric present an old visual effect. Background technique [0002] In the 19th century, denim fabrics were made into thick, stiff, tough and wear-resistant jeans, which were deeply loved by the blue-collar class. Afterwards, they experienced fashionable clothing design, diversified fabric quality and structure, and multiple combinations of processing techniques. With the evolution and technological innovation of modernization, serialization of cloth effect and function, and artistic washing process of garments, denim fabrics increasingly meet the various individual needs of people and become a global clothing product suitable for all ages. [0003] Since the 1970s, denim has developed rapidly in my country. According to incomplete statistics, China's annual production of denim has reached more than 2 billion meters, accounting for 1 / 4 of the world, and denim clothing is also 2.7 billion piec...
