Textile Waste from Woollen Yarn Production as Raw Materials for Thermal Insulation Products

Open Access
|Dec 2022

Abstract

In the current research, waste from woollen yarn production was analysed. Woollen yarn waste as raw material was used for the production of soft thermal insulation mats. Two types of mats were produced in a textile plant: thermally untreated and thermally treated. Properties such as the fibre composition, structure, and thermal conductivity of the thermally untreated and thermally treated mats were studied. During the composition analysis of the woollen yarn waste, the quantity of long, medium length, and short fibres was determined. The content of fats, salts, and other organic and synthetic impurities was investigated. The micro and macrostructures and contact zones between the fibres and the binding material were analysed. The dependences of the thermal conductivity on the density of the thermally untreated and thermally treated composites were obtained.
