Abstract
The article describes research studies in the laboratories of the departments of "Spinning Technology" and "Silk Technology". For this purpose were taken samples of cotton fiber and silk waste from the carding machine in the spinning process, 100% cotton fiber waste, 50% cotton fiber, 30% silk, 20% mulberry bark fiber, 70% cotton fiber, 15% silk, 15% mulberry bark fiber, non-woven fabrics were produced from 75% cotton fiber 10% silk 15% mulberry bark fiber blends. The single-period elongation deformation of the obtained non-woven fabrics was determined using the device "Stoyka".
Highlights
A number of essential tasks facing the textile industry today include re-equipment of enterprises, introduction of new technologies, ensuring the efficient use of raw materials, full use of secondary raw materials and fiber waste, increasing the range of new products, increasing exports
Analyzing the results of the study, compared with the performance of non-wovens obtained from 100% cotton fiber secondary raw material, the total deformation content of non-wovens from 50% cotton. 30% silk, 20% mulberry bark fiber decreased by 25.0%, elastic deformation content increased by 42,0%, elastic deformation composition did not change, plastic deformation content decreased by 70.0%, 70% cotton, 15% silk, 15% mulberry bark fiber total deformation content decreased by 25.0%, elastic deformation content increased by 34.0%, elastic deformation content increased by 5.7%, plastic deformation content increased by decreased by 54,0%, 75% cotton 10% silk 15% mulberry bark fiber total deformation content decreased by 25.0%, elastic deformation content increased by 34.0%, elastic deformation content increased by 13.0%, plastic deformation content decreased by 63.0%
Compared to the secondary raw materials of cotton fiber and silk, it was found that the fiber obtained from mulberry bark has a higher elastic deformation and less plastic deformation
Summary
A number of essential tasks facing the textile industry today include re-equipment of enterprises, introduction of new technologies, ensuring the efficient use of raw materials, full use of secondary raw materials and fiber waste, increasing the range of new products, increasing exports. In the world practice research work is carried out aimed at the production of new techniques and technologies, identifying important factors that affect the technological processes of production of nonwovens. In this field, the introduction of methods of fiber separation from mulberry tree post in the efficient use of secondary resources, the wider involvement of secondary raw materials and waste, the study of the impact of secondary raw materials on the technological. The ratio of elastic, elastic and plastic elongation of non-woven fabrics depends on the fiber content and affects their shrinkage, as well as the ability of the garment to retain its image
