格拉夫针布梳理新疆机采棉应用实践

Application Practice of Graft Card Clothing Carding in Xinjiang Machine-picked Cotton

为了提高新疆机采棉梳理质量,详述所用原棉指标、清棉工序设备性能、工艺参数配置以及格拉夫锡林针布、弹性盖板针布、固定盖板针布、刺辊针布和道夫针布的优势及特点;根据新疆机采棉特点,将全套格拉夫针布用于梳棉机生产,对其刺辊预分梳区、预梳理区、主梳理区、整理区、转移区及全车气流控制工艺进行优化和隔距调整;根据格拉夫圆梳和顶梳优势优选精梳器材配置,并对比格拉夫针布更换前后半制品及成纱指标。指出:使用格拉夫针布对新疆机采棉进行柔和梳理,能高效可靠地剔除杂质、棉籽壳、棉结和短纤维;对其清梳、精梳工序进行器材优选和工艺优化,能最大化发挥设备性能,保证纤维制成率和成纱质量,降低纺纱成本。

In order to improve the carding quality of Xinjiang machine-picked cotton,the indexes of raw cotton,the equipment performance of cleaning process,the configuration of process parameters and the advantages and characteristics of Graft cylinder card clothing,flexible flat clothing,stationary flat clothing,licker-in card clothing and doffer clothing are described in detail.According to the characteristics of Xinjiang machine-picked cotton,a full set of Graft card clothing is used in the production of carding machine,licker-in pre-carding area,pre-carding area,main carding area,finishing area,transfer area and air flow control process of whole machine are optimized and adjusted.According to the advantages of Graft circular comb and top comb,comb accessories configuration is optimized,and half products and yarn indexes are compared before and after replacement of Graft card clothing.It is pointed out that the use of Graft card clothing to gently comb Xinjiang machine-picked cotton can efficiently and reliably remove impurities,cottonseed shells,neps and staple fibers.The accessories selection and process optimization of the cleaning and combing process can maximize the performance of the equipment,ensure the fiber production rate and yarn quality,and reduce the spinning cost.
