超声波在丝/绒同浴染色中的应用

文章研究了在有、无超声波2种情况下蚕丝、羊绒及混纺织物的上染速率曲线和超声波用于丝／绒同浴染色提高同色性的可行性。用评定色差等级和测定表面深度K／S值的方法检验丝，绒同色性，并以Lanaset棕B为例，从染色时间、超声波频率、染色温度和阿白格FFA用量等方面进行分析和探讨，最终得到超声波的染色工艺为50℃入染，保温10min后以1℃／min升温到75℃，保温40min。阿白格FFA2％（owf），超声波频率为64kHz。染色后，丝／绒色差等级可达3-4级。

Study on the Rotor Spinning Processing of Spun Silk/Cashmere Blended Yarn

This paper studies rotor spinning blended yam produced of spun silk and cashmere. Nine samples were spun, from three different opening rollers and different navels. According to the Uster test results of yam quality properties, optimum selection is done by using analysis method of combining fuzzy decision-making and fuzzy pattern classification. Experimental plan is designed based on universal rotated experimental design, and the method of confined optimization is used to optimize the speed of opening roller, the speed of rotor and twist factor, according to the results of yam quality test by Uster.

Production of Silk & Wool Blended Worsted Cloth

Wool & silk blended fancy suiting is desinged. Through trial-production with silk sliver and Australian wool top, the spinning technology is investigated, and the relationship of spinning technology, blending ratio and yarn construction is discussed.
