Recycling the Leftover Fabrics for Use in Lining Surfaces as Heat Insulators for Hot Areas

Seham Ali El-Badri Abd El-Azim El Azab, Wafaa Mohamed Ibrahim El-Banna


The study is based on the descriptive experimental method, where the research deals with the creation of a new type of surface insulator and its use as a heat insulator, where the remnants of fabrics and threads are used with paper pulp of different thicknesses to determine the extent of their ability to heat insulation. The two researchers prepared the study samples represented in non-woven with a thickness of 3 cm - 2 cm - 1.5 cm. The research objective lies in highlighting the role of recycling yarns and fabric remnants in reflecting ultraviolet rays, insulating heat, and determining the most appropriate thickness to getting the highest thermal insulation. The results were obtained with a thermal conductivity meter with hot square technology. There is a difference in the value of the thermal conductivity coefficient of the samples according to the thickness used. The higher the thickness of the sample, the lower the coefficient of thermal conductivity, and thus, the higher the thermal insulation value. The results of the thermal conductivity coefficient of the samples under study were, in general, significantly low, which indicates the success of the samples in isolating the surfaces well, as the value was between 0.032 and 0.0178. From here, it is possible to benefit from paper and fabric waste in the material savings resulting from the use of air conditioning devices and high-priced insulators. This is an attempt by the two researchers to save electricity consumption, which increases when air conditioners are used in places with high temperatures for a long time.
