棉镀银纤维混纺纱的纺制

Spinning of Cotton Silver-plated Fiber Blended Yarn

探讨棉镀银纤维混纺纱纺制工艺。分析了镀银短纤维性能特点,采取原料预混,手工喂入梳棉机的方法实现原料混和。针对镀银纤维强力较低,抱合较差,易发生断头的特点,在各工序合理配置工艺参数,采取降低车速、减小张力等措施保证纺纱的顺利进行,纺制出不同混纺比的棉镀银混纺纱,并进行了质量测试。指出:镀银纤维含量较高时,混纺纱的强力随着镀银纤维含量的增加有较明显下降;镀银纤维在纺纱过程中会与机件摩擦而磨损,脱落的银屑会在牵伸机件上形成"银痕",需要定期进行清理;在络筒应采用光电式清纱器。

Spinning processing of cotton silver-plated fiber blended yarn was discussed. Property of silver-plated fi- ber was analyzed. Raw material was blended first then fed into carding machine. According to property of silver-plated fiber lower strength, worse cohesive force, easy to break, processing parameters were set rationally in each process. Ma- chine speed was slowed down and tension was reduced to ensure spinning successfully, finally cotton silver-plated fiber blended yarns with different blending ratio could be produced and yarn qualities were tested. It is pointed out when sil- ver-plated fiber content is higher,blended yarn strength will be reduced obviously while silver-plated fiber content is in- creased. The silver-plated fiber would be abrasion by friction with machine in the spinning process ,the shed silver marks on the draft mechanical should be cleaned periodically. Photo electric yarn clearer should be used in winding process.
