摘要：为实现棉纺环锭细纱机高速自动化生产，介绍采用铝套管胶管、粗磨和未粗磨双层胶管制作胶辊的流程及质量要求，分析胶辊粗磨、细磨砂轮的选用及其表面涂料处理和紫外线光照处理的作用，列举精梳、并条和粗纱工序对胶辊硬度的选用要求，阐述胶圈的质量要求及选用、维护保养。通过胶辊、胶圈试纺，结果表明：选用优质高效的胶辊、胶圈，以及合理的磨砺、表面处理工艺及维护保养措施，能够保证成纱质量，延长胶辊、胶圈使用寿命；涂料和紫外线光照相结合的表面处理方式，能更好地提升纺纱指标和防静电效果；纺纱流程、纺纱速度不同，选用胶辊硬度应不同；双胶圈牵伸应注意硬度、弹性、厚度的搭配，且上胶圈摩擦因数宜略大于下胶圈，采用内花纹胶圈能改善纺纱效果。

Abstract:In order to meet the demands of high-speed and automatic production for cotton spinning machine，introduction is made to the production process and quality requirements of alu-lined cots,cots with coarse ground double-layered tube and unground double layered tubes,and further analysis is done to the selection of grinding wheel for coarse grinding and finish grinding of cots and the effect of coating and ultraviolet light surface treatment of cots,and cautions are given in the selection of cots regarding hardness in combing process,drawing process and roving process,and the quality requirements,matters needing attention in selection and maintenance of aprons are described.Trial spinning with cots and aprons shows that the yarn quality can be guaranteed and the service life of cots and aprons can be prolonged in case of high-quality and efficient cots and apron selected with proper grinding and surface treatment processes and maintenance measures.The surface treatment combining coating and ultraviolet light can improve the spinning index and anti-static effect more significantly.Selection of cots with different hardness depends on different spinning process and spinning speed.Special attention should be paid to conformity of elasticity,hardness and thickness in selection of double draft aprons,and slightly greatness of the friction factor of the upper apron is prefererable to that of the lower apron,and the use of inner grained apron can improve the spinning effect.
Key Words:cots；aprons；hardness；elasticity；grinding；telescoping；yarn quality；maintaining
