本文主要研究彩棉针织物用碱双丝光处理,随后再用纤维素酶单独或结合起来处理,对彩棉针织物色泽及机械性能的影响;对比了不同工艺处理后彩棉针织物的失重率、光泽度、色牢度参数及强度等变化。结果表明,彩棉针织物用双丝光整理是改善色泽和手感的有效方法和途径,如果与生物酶相结合处理,效果尤佳,其光泽度、色牢度、强度等,都较单独丝光处理为好. 相似文献

Knitted fabric is very different from woven fabric due to its more complicated knitting structures. The buckling of knitted fabric sheets subjected to simple shear in the wale direction is investigated analytically in consideration of the large deformation of fabric sheet in critical configuration. The theory on instability of finite deformation is applied to the analysis. All the stress boundary conditions of knitted fabric sheet are satisfied. An equation to determine the buckling direction angle is derived. It is shown that there are two possible buckling modes, flexural mode and barreling mode. The buckling condition equations for the flexural mode and barreling mode are also obtained respectively. Numerical illustrations reveal that only the flexural mode can actually occur and the barreling mode cannot, which agrees with the experimental observations. For a permitted buckling mode on margin boundaries, the critical value of shear amount and the buckling direction angle can be determined. 相似文献
