The quality of textile fabrics is evaluated by physical, mechanical, consumer and hygienic properties. The durability of a fabric is also characterized by its resistance to abrasion. In turn, this durability and breathability of the fabric depends on many important factors, such as the strength of the yarn, the type of fiber, the composition of the yarn and its linear density, the density and thickness of the fabric, the thickness of the fabric, and so on. The abrasion resistance and breathability of a fabric largely depend on its structural characteristics, i.e., the degree of bending and the density of the warp and purl threads. This degree of bending is determined by the area of ​​one or another part of the product and the purl thread. This area is the reference surface of the tissue. In this article, a comparison of the quality indicators of shirt fabrics with twill weave from 100% polyester fiber and 100% cotton shirt fabrics with twill weave, as well as changes in their properties of breathability, wrinkle resistance, abrasion resistance, was studied.

This article shows ways to increase wear resistance and improve the quality of fabric by studying its structural parameters. To achieve this goal, research was carried out on the structure and physical and mechanical properties of fabrics, expanding the range and improving the quality of shirt fabrics. It is shown that the change in the quality of the fabric, i.e., strength and elongation at break, depends primarily on the number and density of fibers in the fabric, as well as on its thickness. Thus, the denser the fabric, the higher its strength, abrasion resistance and lower breathability. In addition, the fiber content of fabrics is of great importance, since the strength of some chemical fibers is higher than that of natural fibers, especially cotton fibers.
