用于再生聚酯纤维的新型MCZH活动盖板针布设计原理和应用

Design Principle and Application of New MCZH Revolving Tops for Regenerated Polyester Fiber

针对目前再生聚酯纤维盖板针布在梳理过程中存在静电集聚、缠绕、落棉增加、嵌杂、纤维沉入齿底等问题,文章根据纤维特点,设计了新型MCZH截切渐密型盖板针布:截切型矩形钢丝提高纤维转移效率、钢丝材质碳元素增加提高耐磨性、大角度降低落棉、渐密植针形式增加梳理效果、底布加厚减少形变、横向针尖密度增加提升拦截梳理效果等。结果表明,其在实践运用中,实现了再生聚酯纤维梳理落棉少、静电小、转移效果好、梳理质量高的效果。

Electrostatic accumulation,winding phenomenon,increased noil,impurities,and fiber sinking into the bottom of the tooth are the common issues faced by revolving tops for regenerated polyester fiber.For this reason,the paper designs the MCZH truncated progressive revolving tops,with a focus on the characteristics of the fibers.The truncated rectangular wire optimizes fiber transfer efficiency;the inclusion of carbon in the wire material bolsters its wear resistance;the implementation of a wider angle minimizes the accumulation of noil;the gradual and compact needle arrangement enhances the combing process;the reinforcement of the base cloth mitigates deformation;and the intensification of the transverse needle tip density elevates interception and combing capabilities.Results indicate that its practical use has achieved the effect of less noil,less static electricity,good transferring effect and good carding quality for regenerated polyester fiber.
