Thesis Title: An investigation of the conversion of fibrous solid waste into CMC warp sizing
Thesis Author: Rhonda Hyden
Abstract: The textile and apparel industries create approximately 176 million tons of fibrous solid waste per year. Apparel manufactures continually try to reduce cut waste, but studies show that 15-20% of the fabric still becomes scrap material. This scrap material that is wasted can be recycled and used as a raw material for a textile warp size. One option for cotton fibrous waste is to convert the cotton into carboxymethyl cellulose or CMC. Previously, CMC has been produced from cotton linters or wood pulp. The purpose of this research was to determine the effects of cotton waste and its conversion to carboxymethyl cellulose (CMC). The cotton waste CMC was also studied for performance as a yarn size. i Prepared fabric, reactive and vat dyed fabrics (with and without durable press finish), and indigo yarn dyed fabric without finish, were the raw material wastes used to make CMC. Each raw material waste was converted to CMC, a water soluble cellulose, and was compared to commercial CMC control. Five of the six cotton waste CMC's performed as well as a commercial grade CMC. The tensile, abrasion resistance, penetration, and encapsulation properties, as well as the desizing performance were compared to commercial CMC. Through further research manufacturers will be able to use their cotton waste as a warp size, saving sizing costs and costs of handling and disposal of waste.
