min-height: 1em; letter-spacing: 0.544px; text-align: justify; text-indent: 0em; font-family: 微软雅黑; color: rgb(127, 127, 127); line-height: 2em; visibility: visible; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; color: rgb(0, 0, 0); visibility: visible; overflow-wrap: break-word !important;">1、由于在加捻前，纱条中单纤维充分伸直，相互平行，而且排列紧密，所以在加捻罗拉钳口处（也叫阻捻罗拉，因为其有阻止捻度传递的作用），纱条直径变得很小，所以基本消除了“加捻三角区”，由于加捻前单纤维充分伸直、平行，没有毛羽伸出纱条主体，所以成纱毛羽很少，特别是3毫米以上毛羽极少。</span></p><p style="margin-bottom: 25px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; text-align: justify; text-indent: 0em; font-family: 微软雅黑; color: rgb(127, 127, 127); line-height: 2em; visibility: visible;

outline: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; text-align: justify; text-indent: 0em; font-family: 微软雅黑; color: rgb(127, 127, 127); line-height: 2em; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; color: rgb(0, 0, 0); overflow-wrap: break-word !important;">3、在紧密纺工艺中，纱条是在完成了工艺规定的牵伸之后再进行聚集，所以其条干不匀的指标没有大的改善，但在其聚集区有对纱条的整理作用，且在加捻罗拉钳口处加捻时纤维的内、外层转移没有传统工艺强烈，所以紧密纱的条干不匀，粗、细节指标比传统纱要好。</span></p><p style="margin-bottom: 25px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; text-align: justify; text-indent: 0em; font-family: 微软雅黑; color: rgb(127, 127, 127); line-height: 2em; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; color: rgb(0, 0, 0); overflow-wrap: break-word !important;">4、由于紧密纱的上述特点，为下道工序提供了非常好的条件，紧密纱毛羽少，所以减轻了上浆、烧毛等工序的压力，在无梭织机的纬纱使用紧密纱时大大减少了引纬的阻力，提高了织机效率。</span></p><p style="margin-bottom: 15px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; text-align: justify; text-indent: 0em; font-family: 微软雅黑; color: rgb(127, 127, 127); line-height: 2em; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; color: rgb(0, 0, 0); overflow-wrap: break-word !important;">5、由于紧密纱纤维排列紧密，和相同号数的传统纱线相比直径小，所以用相同经、纬密织成的布透气性好，布面平整、光滑，是高档的理想用纱。</span></p><div style="text-align: center;
