outline: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; text-align: justify; font-size: 16px; color: rgb(62, 62, 62); line-height: 2em; font-family: 微软雅黑; overflow-wrap: break-word !important;" align="justify">为不同纺纱方法的成纱毛羽数的比较。与传统环锭纱相比，非传统纺纱的有害毛羽数(&gt;3mm)显著降低，其中紧密纱约减少80%，喷气纱约减少85%，涡流纺纱则减幅达90%以上，因而新型纱线均具有良好的后加工特性。由于新型纱线结构使纱线表面更加稳定，后加工的毛羽增加量显著低于传统纱线。特别是作为经纱，在浆纱时可节约浆料约50%，大大提高织机效率，降低织造成本。有资料介绍，在美国使用新型纱线每100m布织造成本可降低2.4美元，飞花减少72%。</p><p style="margin-bottom: 15px;
