Description
Technical Field
The utility model relates to the technical field of textile, in particular to a cotton-nylon fabric with high tearing resistance.

Nylon fiber (polyamide) is the first synthetic fiber appearing in the world, and the most outstanding advantage is that the wear resistance is higher than all other fibers, 10 times higher than cotton wear resistance and 20 times higher than wool, and in the frock fabric or the fabric with other functional clothing demands, the blended yarn of the nylon fiber and cellulose fiber such as cotton is used as the fabric, so that the overall wear resistance of the fabric can be greatly improved, the wear resistance requirement of clothing can be met, and the wearing comfort of the cellulose fiber such as cotton can be maintained.
However, the elongation of the nylon fiber is larger and is 18-45%, and the breaking elongation of the cotton fiber is only 3-7%, which determines the breaking strength factor of the short fiber blended yarn: the breaking strength of the fibers, the cohesion force among the fibers and the breaking elongation difference among different fibers are higher than those of cotton fibers, the friction coefficient of the nylon fibers is low, the cohesion force among the cotton-nylon blended yarn fibers is low, the breaking elongation difference of the two fibers is too large, the strength of the blended yarn is not high, the wear resistance requirement is met, but the yarn strength is reduced, the fabric strength, particularly the tearing strength is low, and the problem that the cotton-nylon blended fabric cannot break through is already solved.
In order to improve tearing strength, a certain proportion of long staple cotton is added into the cotton-nylon blended yarn, or the breaking strength of nylon fibers is improved, but the great difference of breaking elongation of the two fibers causes that the cotton-nylon blended yarn cannot be obviously improved in strength, and the fabric is subjected to chemical treatment processing such as dyeing and finishing, so that the strength is further lost, and the strength performance, particularly the tearing strength, of the cotton-nylon blended fabric cannot be broken through all the time.
