Investigation Of Indicators Of Resistance To Friction Of Warp And Weft Threads Prepared For Silk Carpets

Abstract

The article developed a technology for obtaining high-density silk for silk carpet products. A sequence of technological processes has been selected for the production of high linear density raw silk. The research work was devoted to the preparation of yarn for carpet products, and the properties of raw silk and spun yarns were studied.Abrasion resistance is an important factor in the production of carpet products. In the production of yarn from fibers, in the production of fabrics from yarn, the fibers are subject to friction. This causes the product to deteriorate. This is why it is possible to eliminate the imperfections of the fabric by identifying this feature. The fiber undergoes bending deformation several times before turning into yarn. When the cocoon is spun, a complex yarn is formed from it, and the yarn is spun, a large amount of fiber is bent.A lot of bending process also occurs during the use of the product. The relationship of the bending of the fibers to a large amount is the most important indicator in their physical and mechanical properties. In large-scale periodic loading, the elastic deformation decreases and their transition to residual deformation leads to subsequent rupture or damage of the fibers. The stability of the fibers to elastic deformation is crucial in their abrasion resistance.The new type of VTS-07-08-09 has twisted parameters for twisting the threads. During the theoretical and practical experiments on twisting on the machine VTS-07-08-09, it was found that the number of turns for the body strip is 4000 rpm, the number of turns is not more than 350-400 rpm. It was found that the number of turns for the back is 5000 rpm, the number of turns is 250-300 rpm.
