Problems solved by technology

And when processing pure cotton denim fabric, it needs to be bleached with oxidant potassium permanganate to make the color of the fabric lighter and the style more inclined to antique denim. irreversible damage to the skin and respiratory tract
[0003] In addition, the wearing properties of pure cotton denim fabrics often cannot meet various standards and still need to be improved.

Embodiment 1

[0025] The present embodiment provides a kind of manufacture method of tannin denim cloth, comprises the steps:

[0026] (1) Weaving 1000kg of recycled cotton to obtain spinning yarn with a specification of 100D;

[0027] (2) The spun yarn obtained in step (1) is first warped under the conditions of a drawing tension of 90N and a vehicle speed of 60m / min, and then the spun yarn is spun under the conditions of a penetrant concentration of 2g / L and a temperature of 20°C. The yarn is infiltrated, and finally the spun yarn is dyed under the condition of pH 12 to obtain dyed spun yarn;

[0028] (3) interweaving the dyed and spun yarns obtained in step (2) into 3 / 1 left twill cloth in the mode of warp and weft yarns to obtain denim initial fabric;

[0029] (4) The raw denim fabric obtained in step (3) is singed, skewed and pre-shrunk to obtain a tannin denim fabric with a shrinkage rate of 2.5%.

Embodiment 2

[0031] The present embodiment provides a kind of manufacture method of tannin denim cloth, comprises the steps:

[0032] (1) Weaving 300kg of regenerated cotton and 700kg of organic cotton to obtain a blended yarn with a specification of 150D;

[0033] (2) The blended yarn obtained in step (1) is first warped under the conditions of a drawing tension of 110N and a vehicle speed of 80m / min, and then warped under the conditions of a penetrant concentration of 2g / L and a temperature of 25°C. The blended yarn is infiltrated, and finally the blended yarn is dyed under the condition of pH 13 to obtain the dyed blended yarn;

[0034] (3) interweaving the dyed blended yarn gained in step (2) into 3 / 1 right-hand twill in the mode of warp and weft, to obtain denim initial fabric;

[0035] (4) The raw denim fabric obtained in step (3) is subjected to singeing, biasing and pre-shrinking to obtain a tannin denim fabric with a shrinkage rate of 2.0%.

Embodiment 3

[0037] The present embodiment provides a kind of manufacture method of tannin denim fabric, and the difference with embodiment 2 is, the weight ratio of regenerated cotton and organic cotton is different in step (1), specifically: 500kg regenerated cotton and 500kg organic cotton are carried out Weaving, get the blended yarn that specification is 150D. All the other steps are the same as in Example 2.

Abstract

The invention relates to a tannin jean fabric and a manufacturing method thereof. The manufacturing method comprises the following steps of spinning regenerated cotton; or blending the regenerated cotton with organic cotton; or blending the regenerated cotton, regenerated fiber and coffee grounds; or blending the regenerated cotton, the organic cotton, the regenerated fiber and the coffee grounds;obtaining a spun yarn; sequentially warping, permeating and dyeing the spun yarn to obtain dyed spun yarn; interweaving the dyed yarns into cloth in a warp yarn and weft yarn mode to obtain primary jean fabric; and singeing, skewing and preshrinking the primary jean fabric to obtain the tannin jean fabric. According to the preparation method, four raw materials of the regenerated fiber, the coffee grounds, the regenerated cotton and the organic cotton are reasonably selected, so that pollution is greatly reduced in the manufacturing process, and the wearability of the jean fabric, such as tensile breaking strength, tearing strength, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing and color fastness to sunlight, can be kept at a higher level through scientific proportioning of the raw materials.

Description

technical field [0001] The invention belongs to the textile field, and in particular relates to a tannin denim fabric and a manufacturing method thereof. Background technique [0002] The textile fashion industry generates around 20% of global wastewater and around 10% of carbon emissions (more than all international flights and shipping combined) every year. Although the textile and fashion industry uses only 3% of the world's arable land to grow cotton, 24% of the world's insecticides and 11% of pesticides are used to grow cotton. Producing 1 kilogram of cotton is only enough to produce a pair of blue jeans, and requires 10,000 liters of water, which is equivalent to the total drinking water of a person in 10 years. Stimulated by the fast-selling culture, the environmental pollution of the clothing and textile industry is second only to the oil industry, which is the most polluting industry, and jeans are the biggest source of pollution in the clothing and textile industr...
