INFLUENCE OF THE ANATOMICAL STRUCTURE OF TECHNICAL HEMP FIBERS ON THE HYDROPHOBIC PROPERTIES OF FOOTWEAR PRODUCTS BASED ON THEM

Abstract

The article examines the actual problems of the production of textile shoes from domestic bast fiber raw materials. Hemp raw materials have all the necessary consumer properties to be used for the upper fabric of textile shoes. In order to study all the qualitative properties of this fiber and determine the possibility of application in shoe production, scientists of the Kherson National Technical University conducted a number of experimental studies. Research was aimed at determining not only the physical and mechanical properties of hemp fiber, but also considered the anatomical structure of this type of fiber. In the course of research, it was established that at full maturity of the stalks of industrial hemp, after their mechanical processing using the combing process, the chaff is completely freed from the woody part: phloem, xylem, parenchyma, and a cuticle remains on the outside of the fibers, which gives the fibers hydrophobic properties. To confirm this result, an experiment was conducted on the wettability of hemp cotonine after steaming in order to identify the hydrophobic properties of future raw materials for the shoe industry. According to the results of this experiment, it was confirmed that the presence of cutins on hemp fibers reduces moisture permeability, which is a positive indicator in the use of this raw material for shoe upper fabric. The use of this fiber for the production of raw fabric without processing makes it possible to create textile shoes with water-repellent properties. Further research of this work should be aimed at obtaining mixed yarn based on the fibers of technical hemp, fabric using it. The final stage of this work is obtaining shoes with upper fabric based on this fiber.
