摘要(Abstract):

针对Lyocell纤维易于原纤化的特点和阻燃功能的需要,设计了阻燃与交联同浴整理的方法,选择N-羟甲基二甲基磷酸丙烯酸胺作为阻燃剂,丁烷四羧酸作为交联剂,分别研究了阻燃剂质量浓度、交联剂质量浓度和交联温度对纤维的燃烧性能、抗原纤化能力和纤维强度的影响。结果发现:适当增加阻燃剂与交联剂浓度能提高纤维的阻燃能力与抗原纤化能力,但极易达到饱和且会降低纤维断裂强度;经过优化整理工艺,在阻燃剂质量浓度为250 g/L,交联剂质量浓度为60~80 g/L,交联温度在150℃时,制备了兼具阻燃与抗原纤化效果且具有强度保持率的Lyocell纤维。
In view of the easy fibrillation characteristics and the demand for flame retardancy of Lyocell fiber, the method of flame retardant and crosslinking in the same bath was designed. N-methylol dimethyl phosphate acrylic amine was selected as the flame retardant, and 1,2,3,4-butanetetracarboxylic acid was used as crosslinking agents. The effects of flame retardant concentration, crosslinking agent concentration and crosslinking temperature on fiber properties were studied. It was found that the proper increase in the concentration of flame retardant and crosslinking agent could increase the flame retardant performance and anti-fibrillation ability of the fiber but it was easy to reach saturation and would reduce the fiber strength.After optimizing the finishing process, when the flame retardant concentration was 250 g/L, the crosslinking agent concentration was 60~80 g/L, and the crosslinking temperature was 150 ℃, a flame retardant and anti-fibrillation Lyocell fiber with strength retention was prepared.
