max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　①煮练对光泽的影响。如煮练不匀不透，煮练后清洗不善，棉纱含残碱较多，致使毛细管效应不匀，丝光碱液渗透困难，纤维不能充分膨化，将影响丝光光度。因此煮练后毛效最好在12cm／30min左右，对丝光较为有利。</span></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　②碱液清洁度对光泽的影响。新配制的碱液一般含杂较少，丝光光泽度亦好。丝光用碱含杂（如纯碱、食盐等）不可过高，否则会阻碍碱液向纤维的渗透，降低纤维的膨化程度，影响丝光效果。丝光用碱液一般纯碱含量不宜超过159／L，食盐含量不超过20g／L。若用回收碱做丝光，应进行苛化处理，碱液中的杂质及纤维绒毛都要处理，确保碱液清洁度。</span></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　③碱液温度对光泽的影响。丝光时应严格控制碱液温度，碱液温度过高则影响丝光效果；碱液温度过低影响碱液对纤维的渗透，也使丝光效果变差。当碱液温度在15℃时，丝光光泽较为理想。但在实际生产中，多数要利用回收碱，降温有一定困难，为此，一般掌握温度在30～35℃为宜。</span></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　④纱线下机带碱对光泽的影响。丝光效果除了取决于浸碱时间、张力大小和脱碱方式外，还与下机纱线带碱量有关。下机带碱量的多少与辊筒的轧挤及冲洗时间有关，如果纱线丝光后下机带碱量超过一定浓度，就会引起纱线再度收缩而影响光泽，为此，下机的带碱量一定要控制在2％以下。</span></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　⑤水质对光泽的影响。整个丝光过程中，水质的好坏能影响产品质量。丝光时若用碱度较高的水冲洗，由于水中含有钙、镁盐，氯化物，微量的铁、锰盐类，这些杂质将黏附在纤维表面，使光泽减退，手感发硬。所以用水质量和水的净化极为重要，有条件的工厂采用软水则更为有利。</span></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br></p><p style="margin-bottom: 0px; max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="font-size: 14px;">　　⑥纱线捻度对光泽的影响。纱线捻度大小，能直接影响光泽。捻度大的纱线丝光后光泽较好，但对强力有影响，丝光钡值小。捻度小的纱线丝光后光泽略差，但强力高，丝光钡值大，因此用于丝光的纱线捻度应略低。</span></p><p style="margin-bottom: 0px;
