合理梳理,提高纺纱效益

Wise Carding to Improve the Spinning Efficiency

为了提高纺纱效益,减少梳棉工序对后道工序和成纱质量的不良影响,从梳理器材、梳理工艺及刺辊系统演变3个方面展开论述,提出合理梳理,即在充分梳理纤维的同时,使纤维受力均匀柔和,最大限度地避免纤维横向流动和损伤;通过不合理梳理导致效益降低的实例分析合理梳理对梳棉机设计的要求,以及梳棉机刺辊系统的发展趋势,说明提高梳棉机产量和提高锡林速度正相关,但锡林—刺辊间速度差不宜过大。指出:科学的梳理理念是先进梳理器材、先进工艺思想和先进梳棉机型的基础,合理梳理涵盖充分梳理和柔顺梳理理念;梳理器材的进步会使合理梳理过程长期稳定,但应根据纤维特点匹配合理的梳理工艺,科学认知梳理过程中的纤维受力,制定出合理的梳理方案。

In order to improve the efficiency of spinning and reduce the negative effects of car ding process on the downstream processes and yarn quality, discussion is done from three aspects including carding accessories, carding process and the evolution of the licker-in system. The concept of wise carding is put forward, that is, when the fibers are thoroughly carded, the force of the fibers is uniform and soft, and the transverse flow and damage of fibers can be avoided as much as possible.The example of unwise carding with reduction of efficiency claims the requirement of wise carding on the design of carding machine, and the development trend of the licker-in system of the carding machine is put forward.This shows that the increase of carding machine and cylinder speed are of positive correlation, but the speed difference between the cylinder and the licker-in should not be too much. It is pointed out that the scientific concept of carding is the foundation of advanced carding accessories, process and carding machines. Wise carding covers thorough carding and soft carding.The progress of the carding accessories make the wise carding process stable for a long time, but it should match the wise carding process according to the characteristics of the fiber, scientific cognition of the fiber stress in the carding process works out a wise carding scheme.
