Determination of Factors Affecting the Quality of Sized Cotton Yarn Using Screening Experimental Method

ABSTRACT

This research examines screening of the factors affecting cotton-sized yarn gain strength, elongation, stretch, size pick-up, and yarn abrasion resistance. The factors considered in this research are sizing machine parameters like sizing machine speed, squeezing roller pressure, warp yarn tension of various sizing machine zones, warp yarn twist, and viscosity of the size paste. Taguchi design with Minitab software has been used to design and analyze the results of the experiments. The study revealed that viscosity, yarn twist, sizing machine speed, and wet tension affected sized yarn gain strength significantly. Viscosity has maximum contribution to gain strength (34.57%) compared to other factors and has a positive effect on the gain strength of the sized yarn. For stretch percentage and the loss elongation of sized yarn, the wet tension is the most significant factor with 50.30% and 52.13% contribution respectively. Moreover, for the size pick-up and yarn abrasion resistance of sized yarn, the speed of the sizing machine is the most effective parameter with 44.45% and 56.29% contribution, respectively. The screening experimental result revealed the most significant factor that must be further optimized using response surface methods of experimental design.

摘要

本研究筛选了影响棉浆纱增强、伸长率、拉伸度、上浆率和耐磨性的因素. 本研究考虑的因素是浆纱机参数，如浆纱机速度、挤压辊压力、各浆纱机区域的经纱张力、经纱捻度和浆糊的粘度. 使用田口设计的Minitab软件对实验结果进行了设计和分析. 研究表明，粘度、纱线捻度、浆纱机转速和湿张力对浆纱增强有显著影响. 与其他因素相比，粘度对增强的贡献最大（34.57%），并且对上浆纱的增强有积极影响. 对于浆纱的拉伸率和损耗伸长率，湿张力是最显著的因素，其贡献率分别为50.30%和52.13%. 此外，对于上浆纱的上浆性能和耐磨性，浆纱机的速度是最有效的参数，其贡献率分别为44.45%和56.29%. 筛选实验结果揭示了最重要的因素，必须使用实验设计的响应面方法进行进一步优化.

Highlights

• The study reveals that the quality of sized yarn is influenced by various factors, including sizing machine settings, recipe preparation, and yarn properties.

• Viscosity of sized paste significantly influences gain strength, while wet tension is the most significant factor affecting stretch percentage and loss elongation.

• Speed of sizing machine is the dominant factor affecting size pick percentage and yarn abrasion resistance.

• The viscosity of size paste, yarn twists level, and wet tensions are the most influential factors to control in the sizing process.
