Embodiment 1

[0016] The following is the finishing method of weft elastic of pure cotton fabric, and its specific process is as follows:

[0017] 1. Gray fabric weaving: the warp yarn of the fabric is made of 11.7 tex pure cotton yarn, and the weft direction is made of 14.6 tex pure cotton yarn and 50 denier water-soluble vinylon filament wrapping yarn.

[0018] 2. Singeing and desizing: The singeing process requires clean singeing, and the desizing process requires clean desizing. The washing temperature is 95°C to ensure that the water-soluble vinylon can be dissolved.

[0019] 3. Caustic soda mercerizing: caustic soda concentration is 28% aqueous solution, which requires sufficient mercerizing. When processing with expanding device, keep the fabric at 98% of the width after singeing and desizing process, and the washing temperature is 85°C.

[0020] 4. Stenter setting: The composition and weight ratio of the mixed solution in the stenter setting process is softener DT-50B 20g / l, acetic ...

Embodiment 2

[0023] The following is the finishing method for the weft elasticity of pure cotton fabrics with non-ironing resin and dry crosslinking additives. The specific process is as follows:

[0024] 1. Gray fabric weaving: the warp yarn of the fabric is 100% pure cotton yarn of 14.6 tex, and the wrapping yarn of 14.6 tex pure cotton yarn and 50 water-soluble vinylon is used in the weft direction.

[0025] 2. Singeing and desizing: The singeing process requires clean singeing, and the desizing process requires clean desizing. The washing temperature in the singeing and desizing process is 95°C to ensure that the water-soluble vinylon can be dissolved.

[0026] 3. Caustic soda mercerizing: caustic soda concentration is 26% aqueous solution, which requires sufficient mercerizing. When using the expanding device to process, keep the fabric at 98% of the width of the fabric after the singeing and desizing process, and the washing temperature is 95°C.

[0027] 4. Add non-ironing resin: car...

Embodiment 3

[0033] The following is the finishing method for the weft elasticity of pure cotton fabrics with non-ironing resin and cross-linking additives. The specific process is as follows:

[0034] 1. Gray fabric weaving: 100% pure cotton yarn of 14.6 tex is used for warp and weft of the fabric.

[0035] 2. Singeing and desizing: The singeing process requires clean singeing, and the desizing process requires clean desizing. The washing temperature is 95°C to ensure the desizing effect and hand feeling.

[0036] 3. Caustic soda mercerizing: caustic soda concentration is 25% aqueous solution, which requires sufficient mercerizing. When processing with expanding device, keep the fabric at 95% of the width after the singeing and desizing process, and the washing temperature is 80°C.

[0037] 4. Liquid ammonia treatment: the washing temperature is 25°C.

[0038] 5. Pre-softening: It is carried out on a tenter machine. The composition and weight ratio of the mixture are: pre-softening agent...

Abstract

The invention provides a method for conditioning latitudinal elastic force of pure cotton fabric, in particular to a method for processing a pure cotton elastic weft fabric without adding elastic fibers such as spandex, which sequentially comprises the following steps of: weaving grey fabrics, singeing and desizing, mercerizing with caustic soda, stentering and setting and pre-shrinking. The method is characterized in that a pure cotton yarn or a wrapped yarn including pure cotton and water-soluble polyvinyl alcohol fiber are adopted in the weft in the grey fabric weaving procedure; the mercerizing procedure adopts 20 to 30% caustic soda solution; a fabric expanding device is adopted for keeping 80 to 100% the breadth of the fabric after the singeing and desizing procedure; and the fabric expanding device is adopted in the stentering and setting procedure to keep the 100 to 102% the breadth of the fabric after the mercerizing procedure, thereby ensuring the elasticity of the fabric. The process fabric has soft handle, good moisture absorption and permeability, and good elasticity within 15 to 25%. Clothes made from the fabrics are comfortable and natural, and can maintain good flat state and elasticity after washing and drying.

Description

Technical field [0001] The invention relates to a finishing method for weft elasticity of fabrics, in particular to a finishing method for weft elasticity of pure cotton fabrics without elastic fibers. Background technique [0002] Cotton fabric has always been the best-selling textile in the world. It is favored by people because of its bright colors, good air permeability, strong hygroscopicity, comfortable wearing, soft touch, cheap price, and biodegradation. The disadvantage is poor flexibility. With the improvement of people's living standards, the requirements for the wearing comfort of clothing have been greatly improved. At present, in order to increase the comfort of pure cotton clothing when worn, it is an important way to mix a small amount of spandex and other elastic fibers in cotton fabrics, but the fabric is not 100% pure cotton material, and 100% pure cotton fabrics cannot obtain greater elasticity. Contents of the invention [0003] The object of the pre...
