Description

一种低强低伸半消光锦纶6 FDY水晶纱的生产方法 技术领域
本发明涉及化纤锦纶长丝生产技术领域，尤其涉及一种低强低伸半消光锦纶6 FDY水晶纱的生产方法。
背景技术
水晶纱(英文名：voile或crystal yarn)，业内人士常将它称为玻璃纱或巴厘纱(巴里纱)。早期的水晶纱原料是一种以纯棉或者部分涤纶长丝为原料制作而成的面料，使用平纹组织结构织造而成的薄而透明的面料。随着人们不断追求高品质生活，越来越多的水晶纱面料使用部分锦纶长丝作为原料，以提高面料档次和穿着舒适程度。
锦纶长丝主要以她的耐磨、易染、柔软、吸湿好、悬垂度佳的优良性能被应用在水晶纱面料中，使其拥有质地细且薄、密度稀而疏，手感滑爽、悬垂挺阔，步孔均匀、布孔清晰，织物透明、透气性好，富有弹性、穿着舒适等优点。一定锦纶含量的水晶纱多用于制作夏季衬衣裙、睡衣裤，也可用来制作头巾、面纱、抽绣的底布、台灯罩、窗帘等服饰用料。
用于水晶纱的锦纶长丝通常以全消光的特色出现，这在水晶纱形成的初期开辟了一定的市场，但是随着人们追求华丽、亮艳、高贵、时尚高品质生活理念的兴起，原有的全消光水晶纱已不适应人们千姿百态服饰的需要。特别是年轻人更加期待既不要刺眼的花枝招展，又毋需阴黑的暗淡无光。
