An analysis of sizing process and the properties of sized warps in wet for WJL

金沢大学人間社会研究域学校教育系
Using orthogonal array method and analysis of variance, the sizing process for Water-jet Looms is fully investigated and the effects of four main factors and their interactions on the properties of sized filaments in wet are also analyzed. Among mechanical parameters, the abrasion-proof decreases very much, and the strength goes down slightly, but the elongation hardly changes in wet condition comparing with that in dry one. The type of sizing agents affects the properties of sized filaments most significantly. The properties of filaments sized by various sizing agents are quite different. Sizing agent No. 1 is the best one. The interactions between factors in sizing process also affected the properties of sized filaments. However, changing the single factor hardly causes the influence for the properties of sized filaments significantly. The optimum sizing conditions are suggested. © 2008 The Textile Machinery Society of Japan.
