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;">　　（1）经轴接头对接16股，使经纱平行退绕，可减少平筘长度，提高平筘质量，节约经纱。</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;">　　（2）调节经轴左右位置，使经纱纱片退绕时边部对齐，防止边部打卷和粘并。</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;">　　（3）发现经轴上有绞头要及时解绞，经轴上有绞头经纱退绕时经纱容易拉伤，有的还会拉断，经纱拉伤后在前分纱区分绞时易产生断头。</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;">　　（4）起机平筘很重要，平筘动作要轻，快，要求每个经轴边纱要对齐，纱片均匀，经纱平行，纱片边部不能厚。</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;">　　（5）平筘后换好织轴开慢车时，由于经纱上下错层或经纱不平行时，筘齿会被经纱拉得前后跳动，这时一定要把跳动筘齿附近的经纱整理一下，使上下经纱层次分明，平行，保证经纱过筘通畅，避免经纱过筘时被筘齿绞断。有的筘齿跳动幅度较大，用眼睛可以看到，有的筘齿跳动幅度较小，用眼睛看不到时，可把手放在筘齿上方，如有筘齿的跳动，手可以感觉到。出现上述问题时，要及时整理好绞筘的经纱，避免开快车时筘齿绞断经纱。</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;">　　（6）穿绞时，由于绞绳处经纱上浆较大，在前分纱区拉动绞绳分开经纱时也很容易拉断经纱，会集中产生断头，如果在穿绞的安排上把穿绞处的这段经纱正好与生头包布一起卷在织轴的轴芯上，那么织轴在布机了机时，穿绞处的这段经纱就是布面的了机回丝，也就是穿绞处的这段经纱即使有断头，也不会影响到布机的效率。</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;">　　（7）穿完绞后，或多或少会在穿绞的这段经纱上产生一些断头，如果马上正常开车，穿绞时产生的断头就会绞筘，这时如果开慢车，等穿绞的这段经纱过筘后，把筘打下，等经纱前行30～40厘米，同时稍微平筘，再把筘打起，这样处理，可以把穿绞时的断头产生的绞筘放过筘，一至产生新的断头绞筘。</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;">　　（8）带浆穿绞时，每根绞绳出浆槽时两个挡车工分别站在浆槽的左右两边，拉住绞绳两端，沿纱片方向前后拉动约40厘米宽，这样使经纱在湿纱时预分纱一次，便于穿绞时绞绳在干区顺利地分纱，可减小绞绳在干区分纱的难度，有效地减少了绞绳分纱时的断头。</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;">　　（9）慢车操作动作要快，尽量减少开慢车的时间，避免慢车时间过长经纱在烘筒上造成过烘，在前分纱区分纱时产生脆断。</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;">　　（10）处理前分纱区断头时，拉出断头的经纱，尽可能放回原位，如果不能放回原位，这根经纱有可能被再次绞断，这就要求挡车工把断纱放回筘后要整理一下经纱，避免再次被绞断。</span></p><p style="max-inline-size: 100%;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　（1）回潮偏大设置。适当加大浆纱回潮，可以使浆纱柔软有弹性，分纱时不易产生脆断，回潮设置8.5%～9.5%为宜。</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）主烘筒温度可偏小设置。浆纱的烘干是通过两个浆槽的各一组预烘和一组主烘共同完成的，预烘是烘刚出浆槽的含水重的纱，主烘是烘经过一次预烘的纱，含水量较小，容易烘干，如果主烘筒温设置较大，浆纱机因故要开慢车时，很容易对经纱造成过烘，产生脆断。如果主烘筒温度偏小设置，也可减轻过烘成度。</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;">　　（3）采用经纱出浆槽不分层的上机工艺，改变纱片在烘区的走向，增大纱片的覆盖系数，可有效改善纱片边部和内部扭转、打结，减少干分区分绞时的断头。浆纱出浆槽能否形成完整的纱片，取决于经纱间的毛羽是否能伸到相邻的经纱上，如果能伸到相邻的经纱上，出浆槽的经纱上浆后浆液就将经纱和毛羽粘在一起，形成完整的纱片，无论烘区张力怎么变化，纱片内部是不会扭转的。实际生产中，当纱片的覆盖系数适当，经纱张力小时，只有边部容易卷边，造成分纱时边部断头。当纱片的覆盖系数不够大，经纱不能形成完整的纱片，整幅经纱只能形成许多小纱束，当经纱张力小时，边部和内部的小纱束都会产生扭转、打结，在分纱时造成的断头会更多。尤其是生产集聚纺和气流纺产品时，纱线毛羽少且短，这种现象就更为严重。这时采用经纱出浆槽不分层进预烘可以增加经纱在烘区的覆盖系数，不至于撕破湿纱片，破坏纱片的完整，可大大减少前分纱区断头。当经纱覆盖系数过小时，可采用走单浆槽浆纱的方法来增加纱片的覆盖系数，从而达到减少前分纱区断头的目的。单浆槽浆纱因为增加了浆槽的覆盖系数，上浆会困难些，要在调浆工艺上稍作调整，确保上浆质量。</span></p><p style="max-inline-size: 100%;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　（1）经纱通道清洁。通道清洁是浆纱的必要条件，浆辊上附着浆片容易造成浆斑疵点或断头，浆辊和导辊间附着坚硬的异物，容易压伤或压断经纱，严重的在浆槽就断头，不严重的在前分纱区也会造成断头。</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）金属辊上的刀痕要及时修复。金属辊上的刀痕是处理金属辊上的断头时，由于错误的割纱方法造成的，它会象刀口一样会割伤经纱，及时修复刀痕可以有效减少由此造成的经纱断头。在操作上要正确按平挑法割纱，减少对金属辊的伤害。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　（3）烘筒的薄膜阀开关要灵敏。经纱是靠烘筒进行烘干的，烘筒正常开车时，温度在80-100之间。在浆纱处理断头操作、穿绞操作、落轴操作处理断头时，必须开慢车，开慢车时，烘筒蒸汽阀漏气就会使烘筒的温度急剧上升，经纱长时间过度烘烤会造成前分纱区经纱脆断。烘筒薄膜阀的良好开关作用可避免慢车时烘筒温度上升过快，对经纱造成过烘而引起的断头。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　结束语</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;">　　前分纱区断头撞筘是浆纱操作上处理起来最复杂的一种断头，又是最常见的一种断头，经纱在烘区扭转、打结会造成严重的前分纱区断头，断头后处理又要打慢车，打慢车时又会造成经纱在烘区扭转、打结和经纱在烘筒上的过度烘干，又形成新一轮的脆断，处理不好是一个恶性循环。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　首先，采用经纱出浆槽不分层进预烘或直接单浆槽浆纱的上机工艺可有效地减少前分纱区断头，效果非常明显；</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;">　　其次，操作上，除平好筘和减少开慢车时间外，把穿绞处的那段经纱卷在织轴的轴芯上，穿绞处的这段经纱即使有断头，也不会影响到织轴质量和布机的效率；</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;">　　第三，设备上要保持烘筒的薄膜阀开关灵敏和经纱通道及浆辊光洁。注意了以上的细节，可有效预防和减少前分纱区的断头，提高织轴质量，提升布机效率。</span></p><p style="max-inline-size: 100%;
