Production method of tear-resistant fabric

Abstract

The invention discloses a production method of tear-resistant fabric. The method comprises the steps as follows: firstly, twisting and spinning polyester cotton yarn into warp and weft, and weaving the warp and the weft into gray fabric, wherein the warp is 21S / 2, the weft is 14S / 2, the warp and weft density of the gray fabric is 66*38; sequentially performing turning, alkali cleaning, boiling off, half bleaching, hot setting, function adjustment, tentering setting, calendering and coating tretament on the gray fabric to prepare the tear-resistant fabric. On the premise that the gram weight ofthe fabric is kept unchanged, the overall tear strength and balance of the fabric are improved. Singeing, mercerizing and sanding processes in the traditional after-finishing process are abandoned, effects of these processes on the tear strength of finished fabric are avoided, meanwhile, the alkali cleaning, boiling off and half bleaching time is shortened, the calendering force is reduced, the overall tear strength and balance of the fabric are further improved on the premise that the gram weight of the fabric is kept unchanged, composition is facilitated, and fabric consumption is reduced.

Description

technical field [0001] The invention relates to a production method of a fabric, in particular to a production method of a tear-resistant fabric. Background technique [0002] Polyester-cotton blended fabric is a variety developed by our country in the early 1960s. The fiber has the characteristics of crisp, smooth, quick-drying, durable, stable size, small shrinkage, and easy to wash, so it is deeply loved by consumers. favorite. Canvas made of polyester-cotton fabric can be used to produce trousers, jackets, shoe uppers, work clothes, outdoor tents, etc. However, the existing canvas has the main problem of uneven warp and weft tear strength, and usually the warp and weft tear strength is much higher In the weft direction, the tear strength in the weft direction is low, which leads to the need to distinguish warp and weft typesetting according to the use requirements when cutting the fabric, which not only causes inconvenience in typesetting but also increases fabric consu...

Canvas made of polyester-cotton fabric can be used to produce trousers, jackets, shoe uppers, work clothes, outdoor tents, etc. However, the existing canvas has the main problem of uneven warp and weft tear strength, and usually the warp and weft tear strength is much higher In the weft direction, the tear strength in the weft direction is low, which leads to the need to distinguish warp and weft typesetting according to the use requirements when cutting the fabric, which not only causes inconvenience in typesetting but also increases fabric consumption, so how to do it without changing the weight of the fabric? , the preparation of a fabric with improved overall tear strength and balance has important practical and economic value
