Blending of Cotton and Poly (lactic Acid) Fiber: Combined Optimization of Blend Ratio and Yarn Twist Using Mixture-Process Design

ABSTRACT

Blending of cotton with poly (lactic acid) fiber, regarded as the natural polyester as opposed to the commonly used synthetic polyester, was systematically done by varying the blend ratio and the yarn twist. This was followed by the combined optimization of both the parameters using a mixture -process experimental design. The study, which took care of the blending limitations in terms of the feasible proportion of the constituent fibers in the blend, their in-between interactions as well as the interactions with the yarn twist, could identify a combination of blend ratio and yarn twist that could produce an optimum/desired blended yarn in terms of the highest desirability function. The method can be adopted for production of optimum-blended yarn in the spinning industry.

摘要

通过改变混纺比和纱线捻度，系统地将棉花与被认为是天然聚酯而不是常用合成聚酯的聚乳酸纤维进行了共混.随后，采用混合工艺试验设计对两个参数进行组合优化.该研究考虑了混合物中成分纤维的可行比例、它们之间的相互作用以及与纱线捻度的相互作用方面的混合限制，可以确定混合比和纱线捻度的组合，从而得出最佳的混合比和纱线捻度./理想的混纺纱具有最高的理想性能.该方法可用于纺纱工业中最佳混纺纱的生产。
