Problems of using hemp fibers in fabrics for shoe upper

Purpose. The studding of consumer characteristics hemp fabrics used for the manufacture of shoe top. Methodology. Theoretical and experimental studies were carried out in the work, which were solved using modern methods and techniques, analysis, measurements in which the current regulatory documentation was used. The determination of the amount of fibers in the threads of the tissues of the experimental samples was carried out using the method of light microscopy. Findings. Every year there is a growing interest in the use of technical hemp in light industry, not only abroad, but also in Ukraine. Many native entrepreneurs in the production of textiles use natural, environmentally friendly hemp fibers. This is due to the high quality properties of the fibers of this culture. Hemp fiber has great wear resistance and strength, even when compared to linen or cotton fibers. Hemp fiber fibers have high hygroscopic properties Due to the porous structure of hemp fiber, the fabric obtained from it is able to absorb moisture up to five hundred percent of its weight. Also, these fibers are hypoallergenic. But, with such quality indicators, hemp fiber has a high breaking elongation, this negatively affects the performance properties of footwear. This article analyzes all the factors that negatively affect the shape stability of the shoe upper fabric, based on technical hemp fibers:- high relative breaking elongation of hemp cottonin – 17.2%; fibrous and percentage composition of warp and weft threads in shoe upper fabrics; the weave of the shoe upper fabric.Based on the above experimental studies, a number of scientific hypotheses have been proposed that will help solve the negative impact of the above factors on the performance properties of industrial hemp footwear. The implementation of these hypotheses will improve the quality of native products made from industrial hemp and make them competitive in the domestic and European markets. Originality. For the first time, scientific hypotheses are presented to eliminate negative factors that affect the performance properties of hemp fabrics that are used for the upper of shoes. The practical value. The conducted experimental research will help to produce finished footwear with high performance properties
