摘 要:探讨木棉纤维纺织品在加工、使用中的损耗情况。测试了木棉纤维纱和织物在加工前后的木棉棉纤维根数比、木棉混纺毛巾在使用前后的木棉与其他纤维根数比及磨损断裂特征、木棉被絮料中纤维碎屑的长度分布情况。研究结果显示:在高密机织物加工中作为经纱的木棉纱磨损量较大;且木棉纤维的磨损量明显大于棉纤维;经使用木棉纤维会产生明显折痕,折痕的最小间隔约20μm;木棉纤维碎屑长度主要集中分布在185μm^465μm之间;木棉碎屑的横断面并不整齐。认为木棉细胞壁上存在约20μm间隔的结构弱环,使用中木棉纤维的断裂是由局部逐渐发展到整根纤维横断面分离的渐进过程,而不是一次性脆断。Breakage and loss of kapok fiber textiles in production and use were discussed. Kapok fiber and cotton fiber number ratio of kapok fiber yarn and fabric treated before and after were tested. Wear breakage characteristics, kapok fiber and other fiber number ratios of kapok fiber blended towel treated before and after were tested. Kapok fiber fragment length distributions in kapok quilt wadding were tested. The research result shows that kapok yarn used as warp in high density woven fabric were wore greater. Wear amount of kapok fiber is obviously larger than that of cotton fiber. Obvious crease would be appeared on kapok fiber, the smallest crease interval is about 20 μm. Length distributions of kapok fiber fragment is mainly between 185 μm - 465 μm. Cross Section of kapok fragment is not uniform. It is considered that about 20 μm structure weak lines are existed on kapok cell wall, breakage of kapok fiber is a gradually developed process from the part to the whole instead of one-off brittle fracture.
