Abstract

The invention discloses a production method for a jean. The method comprises the steps of warping, leasing, cylinder making, untwisting, cloth weaving, dyeing and conducting post-treatment, detection and packaging through a padder, wherein the dyeing step further comprises the following procedures of a, conducting preliminary treatment on a gray fabric, b, conducting printing and size mixing, c, conducting ageing, d, washing the fabric with a continuous rope form washer, e, spraying a potassium permanganate saturated solution with a spraying gun, f, washing the fabric with hot water and then cold water, then conducing dehydration, and g conducting sizing. The production method for the jean has the advantages that the jean does not fade easily after being dyed in the production process, and the hazy printing effect is achieved on the jean.

Description

technical field [0001] The invention relates to a production method of denim. Background technique [0002] In modern life, denim is widely loved by urban men and women because of its wear resistance, thickness, and natural color. However, denim clothes are easy to fade when washed, which makes the denim clothes fade after repeated washing. It affects the beauty of the clothes; secondly, because of the fading during washing, the denim clothes must be washed separately from other clothes, which increases the workload and wastes time. Therefore, the requirements for printing and dyeing of knitted fabrics are getting higher and higher, and personalized printing effects are becoming more and more popular. Contents of the invention [0003] The object of the present invention is to provide a denim production method, the denim produced by the denim has a good printing and dyeing effect and has a hazy printing effect. [0004] The production method of a kind of denim designed...
