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.
