Non-ironing post-finishing technique for cotton fabric

Abstract

The invention relates to a fabric finishing process, in particular to a non-ironing finishing process of a woven cotton fabric. The non-ironing post-finishing process includes the steps of fabric preparation, resin padding, tenter drying, baking, pre-shrinking, and rolling, wherein the fabric preparation includes gray fabric seaming, singeing, desizing, alkali mercerizing, dyeing, and drawing. The steps of web setting and liquid ammonia finishing, wherein, the step of resin padding includes two resin padding steps, and also includes a ventilation step after resin padding and before tenter drying. Due to the adoption of the above-mentioned technical solution, the contradiction between the anti-wrinkle performance of cotton fabric and the strength and wear resistance of the fabric is completely resolved, so that the hand feeling, air permeability and hygroscopicity of cotton fabric continue to maintain the characteristics of cotton fabric, and the anti-wrinkle performance is greatly improved. Improvement, formaldehyde residues are greatly reduced, and energy consumption and sewage discharge can also be reduced.

Description

Technical field

[0001] The invention relates to a finishing process of fabrics, in particular to a non-iron finishing process of woven cotton fabrics. Background technique

[0002] For a long time, pure cotton fabrics have been welcomed by consumers because of their good air permeability, strong moisture absorption, soft hand feeling and comfortable wearing. However, clothing made of pure cotton fabric is easy to wrinkle and not stiff during wearing and washing, and clothing made of pure cotton fabric that is easy to wrinkle affects people's appearance. Obviously, the natural wrinkle-prone nature of pure cotton fabric significantly affects the breadth of use of the fabric.

[0003] There are two process routes for the non-iron finishing of pure cotton fabrics: one is the pre-baking method, that is, the fabric open-width padding resin, open-width baking and other processes are completed by the printing and dyeing factory. This is the traditional process route, and its shortcomings...

Examples

Embodiment 1

[0070] Take cotton dyed poplin as an example, the poplin count is 40*40, the specification is 130*80, and the gram weight is 110 grams per square meter.

[0071] (1) Fabric preparation

[0072] 1. Grey cloth stitching

[0073] The seam of the grey cloth is to sew and connect the grey cloth with the same front and back sides and a firm seam head to ensure continuous production.

[0074] 2. Singeing

[0075] Four burners, two positive and two reverse to achieve clean hairiness on the cloth surface, the fabric is 110 g / m², and the speed is 110 m / min.

[0076] 3. Desizing

[0077] Desizing and desizing to ensure that the desizing rate is over 99%.

[0078] 4. Alkali mercerizing

[0079] The concentration of caustic soda is 240-260 g / l.

[0080] 5. Dyeing

[0081] 6. The stenter is finalized

[0082] The speed is 65 m / min and the temperature is 150°C.

[0083] 7. Liquid ammonia finishing

[0084] The fabric is immersed in pure liquid ammonia (-33°C), puffs from the inside when it evapo...

Embodiment 2

[0103] Take the pure cotton yarn-dyed fabric as an example. The pure cotton yarn-dyed fabric has a count of 40*40, a specification of 130*90, and a weight of 140 grams per square meter.

[0104] (1) Fabric preparation

[0105] Fabric preparation includes the steps of seam, singeing, desizing, alkali mercerizing, and liquid ammonia finishing. Fabrics include yarn-dyed cloth, dyed cloth, printed cloth

[0106] 9. Grey cloth stitching

[0107] The seam of the grey cloth is to sew and connect the grey cloth with the same front and back sides and a firm seam head to ensure continuous production.

Embodiment 3

[0138] Taking pure cotton cloth as an example, the pure cotton cloth has a count of 40 / 2×40 / 2, a specification of 138×66, and a weight of 360 grams per square meter.

[0139] (1) Fabric preparation

[0140] Fabric preparation includes the steps of stitching, singeing, desizing, alkali mercerizing, and liquid ammonia finishing. Fabrics include yarn-dyed cloth, dyed cloth, printed cloth

[0141] 1. Grey cloth stitching

[0142] The seaming of grey cloth is to sew and connect the grey cloth with the same front and back sides and a firm seam head to ensure continuous production.

[0143] 2. Singeing

[0144] Four burners, two positive and two reverse to achieve clean hairiness on the cloth surface, the fabric is 360 g / m², and the speed is 85 m / min.

[0145] 3. Desizing

[0146] Desizing and desizing to ensure that the desizing rate is over 99%.
