Abstract
In recent years, the garment and textile industries generate millions of tons of textile waste every year around the world. Textile wastes are one of the disposed of materials and the sum of disposed of material squander materials expanded from year to year. For this reason, regenerating and utilizing the textile waste item as resources and decreasing environmental pollution may be an extraordinary opportunity. This research is aimed at manufacturing unsaturated polyester composite reinforced with 100% cotton fabric waste for ceiling board application using a manual mixing process followed by the compression molding method. The statistical results showed that mechanical properties of the produced composite samples such as tensile, compressive, flexural, and impact strength are affected by fiber mixed ratio and matrix loading at α = 0.05 . The composite ceiling reinforced with 33 weight % cotton fabric waste and a matrix of 67 weight % unsaturated polyester had a maximum tensile strength of 198 MPa, the flexural strength of 30.1 MPa, and compressive strength of 1105.3 MPa. On the contrary, the false ceiling board made from 10% cotton fabric waste and matrix of 90% unsaturated polyester had a lower tensile strength of 112.6 MPa, flexural strength of 21.5 MPa, and compressive strength of 867.5 MPa. Generally, the manufactured composites’ mechanical behaviors were comparable to existing commercial ceiling boards and the output of this research work can protect the environmental pollution by reducing textile waste disposed to landfills.
Highlights
The textile industry is the world’s second largest polluting industry, accounting for 10% of total worldwide greenhouse gas emissions [1]
This is because when the ratio of textile fabric is high, it will not be compressed by pressure load and result in higher thickness. Due to this ceiling composite made from R10%/M90%, it had the least thickness of 14 mm and the ceiling board made from R40%/M60% had the higher thickness of 24.8 mm than all others
The statistical results showed that all studied mechanical properties of the composite were affected by textile waste loading and matrix ratio at α value of 0.05
Summary
The textile industry is the world’s second largest polluting industry, accounting for 10% of total worldwide greenhouse gas emissions [1]. It is much more important to recycle and use waste items as resources to avoid pollution. Various researchers are attempting to recover and utilize postconsumer wastes to avoid landfills [3,4,5].Textile wastes are divided into two categories, preconsumer and postconsumer. Any clothing or home textile item that is no longer useful to its original user is classified as postconsumer trash [7]. According to the Recycling Council of Ontario, the average person throws away 37 kilograms of textiles annually [8]. In 2018, 17 million tons of textile waste ended up in landfills, according to data from the Environmental Protection Agency, making up 5.8 percent of the total municipal solid waste (MSW) generation that year. The volume of clothing Americans throw away each year has doubled in the last 20 years, from 7 million to 14 million tons [3]
