选用纯棉靛蓝牛仔布作为实验对象,利用激光技术对织物进行生态洗水,对洗水前后织物的表面组成进行了红外光谱分析,拉伸强度、透气率、耐磨性、织物厚度以及K/S值进行了测试。结果表明:当激光功率为75%~85%,加工速度为1万~1.2万mm/min时,牛仔布洗水效果良好,洗水后织物表面无新物质生成,拉伸强度、透气率、K/S值不同程度降低,耐磨性、织物厚度变化并不明显。与传统洗水方式相比,激光洗水更加环保,有效降低了加工成本,符合绿色生产的主题。 相似文献

采用两种计算孔径的方法,分别计算出织物孔径dp、dh。在特定纱线线密度下,研究织物孔径和织物透气率之间变化规律。其次改变纱线线密度,观察纱线线密度变化对织物透气率大小的影响。利用Origin软件拟合织物透气率与纱线线密度、织物经纬纱密度、孔径dp或孔径dh之间的函数关系。研究结果表明,当孔径分别采用dp、dh用作拟合参数时,所得函数计算的透气率与实测透气率的相关系数分别为0.9927、0.9952。由此可见,所建立的拟合函数可用于全棉织物的透气性预测。对于孔径计算方法的选择,采用dh时要比采用dp时,透气率的预测精度略高。 相似文献

对环锭纱牛仔布与转杯纱牛仔布在酵素石磨水洗前后的物理性能进行了测试与分析,研究表明:水洗后两者的断裂强力和撕破强力均有下降,且纬向比经向下降更多;转杯纱牛仔布断裂强力下降远大于环锭纱牛仔布,而后者撕破强力的下降比断裂强度下降更大。此外,酵素石磨水洗有利于改善织物的耐摩擦色牢度,尤其是对转杯纱牛仔布改善更明显,但对耐皂洗色牢度影响很小,对耐酸碱、汗渍、水渍色牢度无影响。 相似文献

In this study, denim fabrics were produced with yarns obtained from cotton fibers (CO), recycled cotton fibers obtained from yarn wastes (r-CO), and fibers produced from recycled PET bottles (r-PET). Enzyme and stone washing processes were applied systematically on these fabrics. Mass per unit area, breaking force, elongation at max force, tear strength, air permeability, and circular bending rigidity of fabrics were measured. The findings showed that r-CO fiber has negative effect on tear and breaking force. Breaking force, elongation at max force, and tear strength values of the fabrics increased depending on the increase in r-PET content. However, fabric handle was negatively affected associated with the r-PET ratio due to the increase in stiffness. Mass per unit area, breaking force, air permeability, and circular bending rigidity values of fabrics decreased after the washing processes. The effect of fibers on enzyme- or stone-washed fabrics showed a change according to finished fabrics. It can be said that fabrics containing r-PET are more resistant than cotton and recycled cotton in various aggressive denim washing methods such as bleaching or different washing process conditions such as rising temperature, and time. 相似文献

The physiological comfort determined by air permeability and moisture management properties of fabrics is influenced by various constructional parameters of the fabric which give woven fabric a porous structure. Evaporation of sweat during wear has the potential to cool the body besides restricting the additional weight of sweat being absorbed by the fabric. In this study, comfort characteristics of denim fabrics with different weft yarn of cotton, polyester and core spun Lycra have been discussed. Effect of enzyme washing and repeated laundering on air permeability, moisture management and drying rate has also been discussed. It was observed that air permeability and water vapour permeability of unwashed denim fabrics with cotton weft yarn are significantly higher than the fabric with polyester and Lycra cotton weft yarns. The wetting time is higher for cotton and Lycra cotton yarn fabrics. One-way transport index is highest for Lycra cotton weft fabrics and lowest for fabrics with polyester weft. Fabrics with polyester weft yarns show highest spreading rate, spreading radius and drying rate due to better wicking and hydrophobic nature of polyester fibres. 相似文献

介绍了一种牛仔成衣的仿旧染色方法,即涂料染色 酵素洗褪毛、褪色 再套染活性染料。在涂料染色前,牛仔成衣先接枝改性,以有利于吸附涂料,再在水浴中加入黏合剂进行交联固色,酵素洗采用酸性纤维素酶,再用活性染料对成衣进行同色套染,最后对成衣进行柔软整理。该牛仔成衣既有浓郁的色调又产生仿旧感。 相似文献
