The low stress mechanical properties of fabrics produced from different spinning systems and their economical impact in clothing sector

Abstract

The tailoring quality of fabrics and the design of garment are greatly influenced by the fabric physical and mechanical and also their low stress mechanical properties such as bending, tensile, shear and compression. Objective measurement of these characteristics leads to making rational decision in selecting fabrics in order to minimize the tailoring problems and improve the quality of finished garment. The thesis involves the measurements of fabrics properties at the mechanical and the low stress mechanical of woven fabrics that produced from cotton yarns 100% (Giza 86) that spun with different spinning techniques (card, comb and open end), in addition to fabrics produced from polyester microfiber yarns. The tests applied to woven fabrics involve tensile strength, elongation, tearing strength, crease recovery and absorption. In addition to that; using the FAST system instruments to test the low stress mechanical properties, including fast-1 thickness meter, fast-2 bending meter and fast-3 extension meter to measure the low stress mechanical properties of these fabrics. In this study, the cotton yarns used have been spun by Misr-Iran Co., Al-Suez City, and the fabrics produced from polyester microfibers obtained by Al- Nahawy Tex Co., 10th Ramadan City, Egypt. All woven cotton fabrics produced have been woven on Sulzer Brothers weaving machine (PU), Machine No. 91182665, Switzerland; by AL- NASR spinning &weaving Co. (Al-chourbagui), Cairo, Egypt. And then have been bleaching bath by MAF Dyeing Co, Cairo, Egypt.
