Problems solved by technology

In order to keep warm, there are denim-like fabrics that use all-wool jeans that can keep warm on the market. Because the wool does not fade, it cannot achieve the effect of washing, not beautiful enough, and the price is high.
The common denim fabrics are mostly pure cotton interweaving. Although the washing effect can be achieved, the wear resistance is poor and it does not keep warm. Moreover, because the cotton fibers are easily faded after dyeing, the denim fabrics cannot maintain their original color for a long time. some chroma

Embodiment 1

[0021] A preparation method of denim fabric, after twisting the warp and weft yarns, dyeing the warp yarns with indigo, and finally weaving the weft yarns and the dyed warp yarns to satin to obtain fabrics, and then sequentially desizing, washing, softening, and shaping, and the final product Inspect and roll the package. During the desizing process, the remaining color stains and impurities in the fibers can be removed; the finishing process is as follows: the washed and dried fabrics are placed in a softening solution to make the fabrics , the waterproof, antistatic and hand feeling have been significantly improved; during the setting process, the fabric is dried in an open width and then checked to ensure that there is no problem with the fabric surface, and the fabric can be set by a high-temperature setting machine according to the user's requirements.

[0022] Among them, the warp yarn is twisted from staple fiber and wool, and the twist range of the staple fiber is 250-3...

Embodiment 2

[0038] Compared with Example 1, most of them are the same, except that it is further defined in this example:

[0039] Before twisting, the wool is scoured first. The scouring process is as follows: soap is used as detergent, sodium carbonate is used as builder, the pH value is controlled at 8-9, the temperature is 40-55°C, and the scouring time is 10°C. ~20min. The mass dosage of the soap is 2% to 4% of the mass of the raw wool to be treated, and the mass dosage of the sodium carbonate is 2% of the mass of the raw wool to be treated.

Embodiment 3

[0060] Compared with embodiment 1 or 2, most of them are all the same, except further defining in this embodiment:

[0061] The indigo dyeing process is specifically: weigh the warp yarn and the indigo dye according to the mass ratio of warp yarn: indigo dye=1:(1.8~2.2), soak the warp yarn in the indigo dye for dyeing, take out the soaked warp yarn and carry out air-drying, after air-drying Promptly obtain the finished warp yarn of dyeing. Wherein, the indigo dye is an acid dye, which is formed by mixing natural indigo and plastocyanin in a weight ratio of 1:(0.65-0.85), preferably, the weight ratio of natural indigo and plastocyanin is 1:0.75. The soaking temperature is 35-45°C, the soaking time is 1.5-2.5h, the air-drying temperature is 80-85°C, and the air-drying time is 30-50min.

Abstract

The invention relates to a denim fabric preparation method which comprises the steps: twisting warp yarns and weft yarns, carrying out indigo dyeing on the warp yarns, then carrying out satin weavingon the weft yarns and the dyed warp yarns to obtain the fabric, and sequentially carrying out desizing, water washing, softening finishing and shaping to complete the denim fabric preparation. Compared with the methods in the prior art, the jean fabric can be washed with water to achieve the jean washing effect, and it can be guaranteed that the warm keeping requirement of the user can be met in autumn and winter cross seasons.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a preparation method of denim fabrics. Background technique [0002] Denim clothing is enduring all over the world due to its rough, casual and comfortable style. Denim fabrics are continuously derived and developed with the development of denim clothing. According to different spinning methods, it can be divided into single yarn, ply yarn, filament yarn and double strand yarn. In order to realize the purpose of keeping warm, the imitation denim fabric of jeans that can keep warm and adopt all-wool has appeared on the market at present. Because the wool does not fade, it cannot achieve the effect of washing, is not beautiful enough, and the price is high. The common denim fabrics are mostly pure cotton interweaving. Although the washing effect can be achieved, the wear resistance is poor and it does not keep warm. Moreover, because the cotton fibers are easily faded after dyeing, the deni...
