Laser-patterned knitted denim fabric and preparation method thereof

Abstract

The invention discloses a preparation method of laser-patterned knitted denim fabric. The preparation method comprises steps as follows: raw materials are selected; yarn is dyed; pure cotton fibers, bamboo fiber, polyester fibers and PBT (polybutylene terephthalate) fibers are woven to form 100 g / m<2>-250g / m<2> gray fabric; the woven denim gray fabric is sequentially treated through processes of singeing, mercerization, preshrinking washing and enzyme washing; laser patterning is performed; the laser-patterned knitted denim fabric or ready-made clothes is prepared through afterfinish, easy-care treatment and other processes. Compared with a conventional water washing method, the laser-patterned knitted denim fabric is subjected to laser patterning and TiO2 modification treatment, the technological process is simple, the working efficiency is high, the cost is low, sewage discharge is greatly reduced, the water consumption is reduced, the environment of the washing water industry is improved to a great extent, and the water washing time is saved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a laser pattern knitted denim fabric and a preparation method thereof. Background technique [0002] The origin of jeans: Jeans, known as "Jeans" in English, were first recorded in 1567. They are the name of the pants worn by merchant sailors from the Italian port city of Genoa, namely "Genoese" Genes". Since the 1860s, the famous name "Jeans" was officially adopted by Levi's company. Before that, people called it "Waist High Over all" and "Pants". [0003] Jeans originated from the gold rush in the western United States in 1849. At that time, the first batch of immigrants to set foot on the American mainland, they can be said to be poor and white, and they had to work hard. Intense labor makes clothes easy to wear and tear, especially in 1849 when miners swarmed into California, forming the famous gold rush at that time. Since the clothing material is very easy to...

Problems solved by technology

However, the above-mentioned old-fashioned denim washing methods are random, uncertain, non-reproducible, and seriously polluting, and take a long time, low efficiency, and many uncontrollable factors, which are not suitable for the development direction of modern textiles.
