In this study, the influence of different process variables on mechanical properties of cotton thread to be used as reinforcement thread has been investigated and the conditions for imparting minimum elongation and maximum tenacity are identified. Single yarn twist, plied yarn twist and mercerization stretch are optimized based on the responses evaluated. The optimization of the parameters has been carried out by using response surface methodology. It is observed that the thread elongation is significantly affected by mercerization stretch setting followed by single yarn twist and plied yarn twist. Tenacity of reinforced thread is highly influenced by plied yarn twist than that of mercerization stretch setting and single yarn twist. Optimized conditions for single yarn twist, plied yarn twist and mercerization stretch are 769turns/m, 767turns/m and 2.5% respectively.

工艺参数对牵伸围裙加强层用棉缝线拉伸性能的影响

在这项研究中，研究了不同工艺变量对用作增强线的棉线机械性能的影响，并确定了赋予最小伸长率和最大韧性的条件。根据评估的响应，优化单纱捻度，合股纱捻度和丝光化拉伸度。通过使用响应面方法对参数进行了优化。观察到丝光伸长率受丝光化拉伸定形，单纱加捻和合股纱加捻的影响很大。与丝光拉伸定型和单纱捻度相比，合股纱捻度对增强线的韧性影响更大。单纱捻度，合股纱捻度和丝光化拉伸的最佳条件为769turns / m，
