Investigation of the Properties of Denim Fabrics Dyed with a Short Process with Sulfur Dyeing

ABSTRACT

The major role played by the textile industry in environmental pollution, sustainability of resources, and the proliferation of competitors have imposed many responsibilities on business. Important among these duties is producing environmentally friendly products, fit for purpose, and cheap; while using less water, chemicals, energy and time.

In this study, an innovative dyeing method is developed as an alternative to conventional sulfur-dying applied in rope dying. Innovative feature of this study is that the developed dyeing process is an environmentally friendly process based on the decrease in the amount of use of water, chemicals, etc. By this new process, conventional denim fabric properties have been tried to be obtained with less processes, use of water and chemicals. The color and selected performance values of fabrics dyed using both of these methods were comparatively examined. According to the results; the properties of fabric treated with the newly developed dyeing method, which has lower consumption are very similar to those of the conventionally dyed fabrics. The warp tensile and tear strength values of the fabrics dyed using the innovative method decreased, while the values in the weft direction increased. Fabric dyed with the conventional method has the highest K/S value, but the lowest L* value. The rubbing fastness value of the fabric dyed with the innovative method was better.

摘要

纺织业在环境污染、资源可持续性和竞争对手扩散方面发挥着重要作用, 这给企业带来了许多责任. 在这些关税中, 重要的是生产环保产品, 适合用途, 价格便宜; 同时使用更少的水、化学品、能源和时间. 在本研究中, 开发了一种创新的染色方法, 作为绳状染色中传统硫染色的替代方法. 本研究的创新之处在于, 开发的染色工艺是一种基于减少水、化学品等用量的环保工艺. 通过这一新工艺, 尝试用较少的工艺、用水和化学品来获得传统牛仔布的性能. 比较了两种方法染色织物的颜色和选定的性能值. 根据结果; 采用新开发的染色方法处理的织物的性能与传统染色织物的性能非常相似, 且能耗较低. 采用创新方法染色的织物经向拉伸强度和撕裂强度值降低, 而纬向拉伸强度和撕裂强度值升高. 用常规方法染色的织物K/S值最高, L*值最低。采用创新方法染色的织物摩擦牢度值较高.
