Goods reinforcement from waste leather, fabric, and low‐density polyethylene by using plant binder

Abstract

The apparel industry is considered to be one of the most polluting manufacturing industries and it generates a large number of wastes that can harm the environment. Ignorance of the waste of finished and used leather and fabric leads to environmental pollution. Converting this solid waste into efficient products is proving to be a challenge. The article examines the possible use of waste leather, fabric, and low‐density polyethylene to develop composites using plant binder. This composite material has a comparable tensile strength (23.6 ± 0.16 μm), the flexibility of 89%, and very reasonable elongation at break (31.40%) when compared to the standard reinforcement material of leather goods since the commercial reinforcement have tensile strength of 15–25 μm; flexibility 50%–90% and 25–40 (Teklay, 2018). The mechanical properties of the flexible composite were promising and made it possible to use it in the leather and textile industries in goods manufacturing as reinforcement of bag. Therefore, the study uncovered a new concept for making composite materials that are environmentally friendly and cost effective as reinforcement of bag manufacturing.

Production and Characterization of Flame Retardant Leather Waste Filled Thermoplastic Polyurethane

“…In the limited number of studies, the effect of LW on the electromagnetic shielding and flame-retardant properties of the materials has been investigated. Enhancements in wear resistance, ,, hardness, ,,, elastic modulus, ,,, tensile strength, − ,− flexural strength, tear strength, toughness, , electromagnetic shielding, − and flame retardancy , have been observed.…”

“…The inherent fibrous structure, high protein content, thermal insulating character, and sound deadening properties of leather waste (LW) increase its potential use in composite applications. LW is used as a biobased filler in various thermoplastic matrix materials including, poly­(vinyl chloride), , polyacrylonitrile, poly­(vinyl alcohol), − ethylene vinyl acetate, , polyethylene, − acrylonitrile butadiene rubber, polyamide, thermoplastic starch, poly­(lactic acid), and thermoplastic polyurethane (TPU). − The mechanical behaviors of the resulting filled materials have been a focus. In the limited number of studies, the effect of LW on the electromagnetic shielding and flame-retardant properties of the materials has been investigated.…”

Examples of Bag Design From Waste Leather Parts as Material Within the Scope of Sustainability

“…Example: It is easier to recycle waste products in high-income, industrialized countries. When waste is managed correctly, the need for natural resources and the damage to the environment are reduced (Alemu et al, 2021(Alemu et al, , s. 2788.…”
