Abstract

The textile industry's product range includes not only fabrics, nonwovens, special clothing and footwear, but also textile haberdashery products such as tapes, braids, cords, and other items made from them. It's hard to imagine modern clothing and footwear without cords. With rapidly advancing technology, the challenges of developing this group of textile products are becoming increasingly complex and require an individual approach.

In some cases, cords are flexible load-bearing elements. Therefore, their breaking load is one of the most important indicators for the production of shoe, household, technical and other cords as it characterizes their strength.

The aim of this study is to determine the influence of the structure and raw material composition of cords with identical specified process parameters on their strength characteristics. For the analysis, groups of cords were formed so that they had the same linear density and raw material composition. The braided and knitted cords were selected so that the linear density of a cord with the specified parameters of the first group was as close as possible to the linear density of a cord made from the same type of raw material of the second group.

Analysis of the experimental data revealed that the cord strength values depend not only on the physical and mechanical properties of the original yarns used in the cord but also on the scale factor. The main causes of reduced cord strength are loss of strength of the original components during processing and the complex spatial arrangement of the yarns in the cord, resulting in sections not parallel to the cord axis.

These results have important practical implications for the development of cords from different types of raw materials with specified parameters and can solve the problem of optimizing production in the textile and haberdashery industry depending on the target strength and weight of the product.
