纯棉纱线合股数对织物性能的影响

为研究纯棉纱线合股数对织物力学性能和保形性的影响,采用线密度相同的单纱、双股线、3股线、4股线4种股线类型,以适当的经、纬密分别织制成平纹、斜纹、缎纹组织的织物.对织物的拉伸性能、撕裂强力、拉伸弹性、折皱回复性、悬垂性、弯曲性进行测试与分析.结果表明:3股线织物的断裂强力和撕裂强力较大,4股线织物的断裂伸长率较大,双股...

Influence of ply number of cotton yarns on fabrics performance

In order to study the effect of the ply number of cotton yarns on the mechanical properties and shape retention of woven fabrics,single,double,triple and quadruple plied yarns with the same fineness were used for making fabrics with appropriate warp and weft densities,using the plain,left twill and satin weaves.The tensile properties,tear strength,tensile elasticity,wrinkle recovery,drapeability and bendability of the fabrics were tested and analyzed.The results show that the fabric with 3-ply yarn has a higher breaking strength and tear strength,the fabric with 4-ply yarn has a higher elongation at break,and the fabric with 2-ply yarn has a greater tensile elastic recovery rate.For the plain weave fabrics,the fabric made from the 2-ply yarn demonstrated better wrinkle recovery than that from single-ply yarn.The wrinkle recovery of the twill and satin fabrics deteriorates as the yarn ply number increases.The plain woven fabric made from 2-ply yarns have good drape,but not as good as the twill and satin fabrics,and fabric using single-ply yarn has better bending properties than other fabrics.
