Problems solved by technology

[0002] Denim jackets currently on the market are mainly single-layer non-stretch denim fabrics, which lack elasticity; as jacket fabrics, they are less comfortable to wear. Secondly, single-layer denim fabrics have no film treatment, and the overall fabric feels hard and lacks elasticity. And wrapping power, no waterproof, water pressure resistance, rainproof and other functions; single-layer denim fabric has poor adhesion fastness, and the shrinkage rate of TPU film and fabric is quite different after washing, the film will fall off, and the fabric will foam.

Embodiment 1

[0021] The preparation method of high fastness elastic denim fitting fabric comprises the following steps:

[0022] S1, the initial treatment of the fabric and base fabric, the fabric provided is a mix of 95% cotton and 2% spandex denim. The warp yarn count of the fabric is 18S combed cotton slub yarn, the warp density is 115 per inch, the weft yarn count is 21S, and the weft density is 70 per inch. The steps of face cloth treatment are: warping, dyeing, weaving, singeing, long car desizing, mercerizing and finishing. Available in 20D mesh with 100% nylon base fabric. The dyeing dyes in the primary treatment are acid dyes. The processing steps of the base fabric: gray fabric, desizing, dyeing, water setting.

[0023] S2, the face cloth is pre-shrunk, and the pre-shrinking treatment adopts a loose dryer, which is dried in water without any pressure in the weft direction, and the shrinkage rate in the weft direction is receded. The shrinkage rate is controlled at less than 5...

The warp yarn count of the fabric is 19S combed cotton slub yarn, the warp density is 116 per inch, the weft yarn count is 23S, and the weft density is 71 per inch. The steps of face cloth treatment are: warping, dyeing, weaving, singeing, long car desizing, mercerizing and finishing. Available in 21D mesh with 100% nylon base fabric. The dyeing dyes in the primary treatment are acid dyes. The processing steps of the base fabric: gray fabric, desizing, dyeing, water setting.

[0032] S2, the face cloth is pre-shrunk, and the pre-shrinking treatment adopts a loose dryer, which is dried in water without any pressure in the weft direction, and the shrinkage rate in the weft direction is receded. The shrinkage rate is controlled at 4% in the r...

Embodiment 3

[0039] The preparation method of high fastness elastic denim fitting fabric comprises the following steps:

[0040] S1, the initial treatment of the fabric and base fabric, the fabric provided is a mix of 98% cotton and 5% spandex denim. The warp yarn count of the fabric is 20S combed cotton slub yarn, the warp density is 117 per inch, the weft yarn count is 25S, and the weft density is 72 per inch. The steps of face cloth treatment are: warping, dyeing, weaving, singeing, long car desizing, mercerizing and finishing. Available in 22D mesh with 100% nylon base fabric. The dyeing dyes in the primary treatment are acid dyes. The processing steps of the base fabric: gray fabric, desizing, dyeing, water setting.

[0041] S2, the face cloth is pre-shrunk, and the pre-shrinking treatment adopts a loose dryer, which is dried in water without any pressure in the weft direction, and the shrinkage rate in the weft direction is receded. The shrinkage rate is controlled at 3% in the r...

Abstract

A method of preparing a high-fastness elastic jean adhered fabric is provided. The method includes surface fabric treating steps including beaming, dyeing, weaving, singeing, long-vehicle desizing, mercerizing and finishing; base fabric treating steps including preparing a grey fabric, desizing, dyeing and sizing with clear water; a surface fabric preshrinking step adopting a loose dryer, with water treating and drying being performed under a condition of no weft tension to reduce a weft shrinkage rate; a step of tightly pressing and adhering the surface fabric and a TPE film; a step of subjecting the adhered surface fabric and the TPE film to evaporation curing; a step of adhering the adhered surface fabric and the base fabric; a step of subjecting the surface fabric and the TPE film which are adhered to evaporation curing; and a water pouring step, namely a step of performing water pouring surface fabric treatment by adopting a waterproofing agent the liquid rate of which is 30-50%, and performing first-stage drying and second-stage drying. The method improves fabric fitting fastness, and increases water pressure resisting and water pouring resisting functions, and the like.
