margin: 0px; padding: 0px; border: 0px none; z-index: 0; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">  答&nbsp; Lyocell纤维是近年来研制开发并得到迅速发展的新型再生纤维素纤维。Lyocell纤维集棉的舒适性、粘胶的悬垂性、涤纶的强度和真丝的手感于一身,由于其属于纤维素纤维,所以织物的吸湿性能良好,并且织物和成衣具有非常好的湿稳定性,因此这种新兴的再生纤维素纤维,自投放市场之后,即受到消费者的广泛欢迎。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">  Lyocell纤维制品在湿态下,经机械外力摩擦作用,会产生明显的原纤化现象,这种现象表现为纤维纵向分离出更细小的原纤,在纱线表面产生毛羽。原纤化产生的原因是Lyocell纤维具有较高的轴向取向度,微原纤问的横向结合力较弱,在湿态下纤维的高度膨化更加减弱了这种结合力,这种结合力的减弱使纤维在自身或金属的摩擦作用下,皮层纤维脱落,残留的皮层纤维纵向开裂,形成较长的不均匀的原纤茸毛。Lyocell原纤化的特性使这种纤维织物成品风格有两种类型,一种为利用纤维的原纤化特性,通过初级原纤化、酶处理和二次原纤化,生产出桃皮绒风格的产品,另一种为在酶处理后不进行二次原纤化,生产出表面整洁的光洁面织物。Lyocell纤维易于原纤化的性能虽然给生产非织造布、过滤材料和桃皮绒风格的织物带来了方便,但却给光洁面织物的生产和使用带来麻烦,如生产中加工工艺的控制、设备和助剂的选用;使用过程中织物易起毛、起球,并且色光会发生变化。另外,Lyocell面料制成的服装经过多次日常洗涤后的严重原纤化,使服装具有很强烈的陈旧感。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">  除了非原纤化Lyocell短纤(如Tencel Al00、Lyocell LF)和Lyocell长丝(如Newcell)的某些织物外,常规Lyocell织物染整加工一般采用前处理(烧毛、退浆、漂白、碱处理)、初级原纤化酶处理及后续加工的工艺流程;对于桃皮绒风格的织物,后续加工过程为染色、二次原纤化、柔软整理、树脂整理等;对于光洁面织物,后续加工为染色、柔软整理和树脂整理。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">  对于光洁面织物,在染整加工过程中必须合理控制和防止Lyocell纤维的原纤化。控制或防止Lyocell纤维的原纤化应从染整加工的前处理、染料的选择和设备的选用上来考虑。</span></p><p style="max-inline-size: 100%;
