大容量涤纶短纤维纺丝油剂的应用

Application of spinning finishes in large-capacity polyester staple fiber production

对比分析了国产TDSL-2005A/B油剂与进口油剂的性能,在100kt/a涤纶短纤维装置上进行了应用实验。结果表明:TDSL-2005A/B型纺丝油剂具有较好的平滑性和抱合性,综合性能好,能有效提高纤维含油水率、延长落桶时间、减少拉伸工序的毛丝和缠辊,成品质量优良,可实现大容量涤纶短纤维纺丝油剂国产化。

The performance of domestic finish TDSL-2005A/B and the imported finishes was contrasted and analyzed. These finishes were applied in a 100 kt/a polyester staple fiber plant. The results showed that the spinning finish TDSL-2005A/B which had fairly good gliding and cohesive properties and favorable comprehensive performance can efficiently improve the moisture content of the obtained fiber, prolong doffing time, decrease breaks and roller wraps in drawing stage. The obtained fiber had excellent quality which ensured that the localization of spinning finishes for large-capacity polyester staple fiber plants can be realized.
