准备工艺流程一般有三种形式，其特点分述如下。</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;">　　(1)预并条机→条卷机：简称“条卷”工艺，总并合数约96~160根，总牵伸倍数约6—13倍。该流程的特点是机器占地面积少，能耗较省，结构简单，便于管理和维修；由于牵伸倍数较小，小卷中纤维的伸直平行度不够，且由于采用棉条并合方式成卷，制成的小卷有条痕，横向均匀度差，落棉较多。该工艺目前在纺织厂普遍采用，适合一般精梳工艺要求。</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;
