Embodiment Construction

[0029] In the following, the present invention will be described in detail and specifically through specific examples, so as to better understand the present invention, but the following examples do not limit the scope of the present invention.

[0030] The present embodiment provides a kind of preparation method of laser pattern knitted denim fabric, comprising the following steps:

[0031] (1) Raw material: choose pure cotton fiber yarn, bamboo fiber yarn, polyester fiber yarn and PBT fiber yarn of 10-60S, preferably the yarn of 30-40S;

[0032](2) Yarn dyeing: the above raw materials are dyed by the following process-wetting pretreatment-washing-dyeing-fixation-washing-soaping-washing-drying-reversing yarn-yarn inspection;

[0033] (3) Weaving: Weaving pure cotton fiber yarn, bamboo fiber yarn, polyester fiber and PBT fiber yarn into 100g / m 2 -250g / m 2 Gray cloth;

[0034] (4) Carry out pre-shrunk washing and enzymatic washing process on the colored gray cloth woven in s...

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".

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...
