margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　1．平幅进布装置</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%;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　除了平幅进布装置的各通用装置外，需增加进布透风装置，主要是为了降低布面温度，避免热量带入碱液而影响丝光效果。</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;">　　2．浸轧槽及绷布辊</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;">　　一般采用立式三辊平幅浸轧机，二浸二轧，前后共两台。在浸轧槽内装有多根导辊，以增加织物在碱液中的浸渍时间，一般可达20s左右。浸轧槽具有可通冷水冷却槽内碱液的夹层。两个浸轧槽间有连通管，以便碱液的流动。第一台浸轧槽压力要小些，可用杠杆加压，以使织物带较多的碱液，有利于碱液与纤维素的作用。第二台浸轧槽压力要大，可用油泵加压，使织物带碱量小，轧液率小于65％，便于冲洗去碱，降低耗碱量。</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;">　　为了延长织物的带碱时间，满足碱对织物充分渗透和反应，同时防止织物溶胀后收缩，在两台浸轧槽之间的机架上方装有十几根上下交替排列的铁制空心绷布辊，直径为460～500mm。一般被动运行，也有主动运行的。为防止织物收缩，织物沿绷布辊的包角面应大些，且后台轧槽的线速度大于前槽，这样，织物的经向有一定的张力，可防收缩，纬向利用摩擦阻力防缩。</span></p><p style="max-inline-size: 100%;

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%;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　布铗扩幅装置的作用是用布铗铗住织物布边，在纬向施以张力，防止织物吸碱后发生收缩，影响产品的光泽、缩水率及尺寸稳定性。</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;">　　布铗扩幅装置是由左右两条环状的布铗链组成的，长度约15～20m。两条环状布铗链由许多布铗用销子串联，敷设在两条轨道上，可以通过螺丝杆调节布铗链的距离，一般调节成橄榄状，即两头小中间大。两头小便于织物顺利地上铗和脱铗，中间大使织物得以扩幅。布铗是由铗身和铗舌组成的，铗身底座装于轨道上，铗身的上部为弓形背，弓形背端用销子装上铗舌，铗舌的不锈钢刀片与铗身嵌有的不锈钢薄片平面接触。铗舌由铗舌柄、不锈钢刀片和触片等组成，如图6-28所示。</span></p><p style="text-align: center;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　织物在布铗链上扩幅运行1／3后，受到3～4只淋洗吸液装置的淋吸去碱。每只淋洗器（图6-30）自织物上方将热水或热洗碱液淋于织物全幅，然后，再由紧贴织物下方的与真空泵相连的表面布满小孔的吸液管（图6-31）吸去。这是一种使织物处于伸张状态下，采用真空吸液，以强化织物中液体交换的洗涤去碱方法。由吸液管吸下的淡碱液，依次排入机下的各淡碱池内，然后按逐步逆流淋洗的原则，分别由各泵把淡碱池内的淡碱液和来自去碱蒸箱的淡碱液，输送到相应的淋洗器。为了提高淋洗效果，使用的淡碱液温度应尽可能高。但对涤棉混纺织物，温度以不超过70℃为宜。</span></p><p style="text-align: center;
