Embodiment 1

[0029] A method for preparing organic cotton denim with knitted fabric effect, comprising the following steps:

[0030] Step S1: knitting: knitting cotton yarn into organic cotton cloth with a knitting machine;

[0031] Step S2: acid-base compound cracking: control the bath ratio of knitted fabric and water to 1:7-10, then add 0.5-2.0 g / L cracking agent and 0.5-3.0 g / L bleaching agent to the water, and heat up to 60 ℃, keep warm for 10-15 minutes, add liquid caustic soda 6-10g / L, then raise the temperature to 90-100 ℃, keep warm for 10-30 minutes, drain water, then add water again, control the bath ratio of pure cotton knitted gray fabric to water as 1:10~ 20. After heating up to 70-80°C, wash the gray cloth for 5-10 minutes and drain water;

[0032] Step S3: Dyeing: injecting dye into the dyeing cavity, placing the cloth after acid-base compound cracking on the roller for dyeing;

[0033] Step S4: Too soft: after dyeing, put the cotton cloth into the airtight tank, accordin...

Abstract

The invention belongs to the technical field of textiles, and particularly relates to organic cotton denim with a knitted fabric effect and a preparation method thereof. Cloth is manufactured through a knitting machine, then the cloth is processed into yarn through conventional procedures, and finished mercerized yarn is prepared through the procedures of knitting, acid-base composite cracking, dyeing, softening, dewatering and drying, calendaring, resin setting, preshrinking and the like. The organic cotton denim produced by the method is full in color and good in dyeing effect, and meets the requirements of market consumers for pursuing fashion and beauty. According to the invention, the acid-base composite cracking process for gray cloth is added before the dyeing process, so that impurities and heavy metal ions on the pure cotton gray cloth can be effectively removed, a high-quality pretreatment fabric is provided for subsequent dyeing, the softness is improved, and the fabric is more comfortable to touch; and the fabric is dyed by combination with a roller, so that the fabric is uniformly dyed and is not easy to fade.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an organic cotton denim with knitted fabric effect and a preparation method thereof. Background technique [0002] Organic cotton is raw cotton that is produced and processed without using any pesticides, chemical fertilizers and genetically modified products, and has been certified by an independent certification agency. In agricultural production, organic cotton is mainly based on organic fertilizers, biological control of diseases and insect pests, and natural farming management. Chemical products are not allowed. It is all-natural and pollution-free cotton from seeds to agricultural products. Today, when actively advocating natural, green, environmental protection and healthy life, organic cotton textiles are becoming more and more popular among consumers. Currently, they are mostly used in infant clothing, high-end underwear, etc., and less used in denim clothing. The tren...
