摘要 探讨精梳纯棉特细号紧密纱生产工艺。针对特细号纱强力低、纺纱难度大的特点,通过选用进口长绒棉,合理配置开清棉与梳棉工艺,提高纤维梳理度,减少纤维损伤,降低短绒含量,采用二道精梳和单道并条工艺,改造细纱加捻机构,拓展捻度范围,采用低速度和较大后区牵伸倍数,结果成功纺制出质量合格的JC 3.2 tex紧密纱。认为:正确选配原料、合理配置工艺是顺利纺制精梳纯棉特细号紧密纱的关键,应进一步解决好二道精梳小卷易黏卷、络筒张力小、筒子成形偏松的问题,完善纺纱工艺,提高成纱质量。 Processing of combed pure cotton super fine compact yam was discussed. According to the characteristics of super fine yarn lower strength,larger spinning difficulty,imported long-staple cotton was used, processing was selected rationally in opening & cleaning and carding process fiber carding degree was improved,fiber injury and short fiber content were reduced, two-times combing and single drawing processing were adopted, twister mechanical in spinning machine was modified, twist range was expanded, lower speed and larger draft multiple in back area were adopted, finally JC 3.2 tex compact yarn can be produced successfully. It is considered that the key to spin combed pure cotton super fine compact yarn are the selection of raw material correctly and processing rationally. Problems should be solved, such as lap licking in combing process,lower winding tension, softer bobbin forming ect. It is pointed out that spinning processing should be optimized, yam quality should be improved.
