margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">　　毛织物所用纱线，主要是由短纤维纺成的单纱和合股线，少量是用于装饰的化纤长丝、丝光棉纱、绢丝以及羊毛与化纤长丝合捻的夹丝纱线和花式纱线等。目前，正在研究使用变形纱、包芯纱等特殊纱线，以改善织物性能，粗纺毛织物主要采用单纱，精纺则采用股线，个别品种采用双经单纬。</p><p style="max-inline-size: 100%;
