棉网清洁器除尘刀隔距对棉结和杂质的影响

为探讨棉网清洁器除尘刀隔距对生条中棉结和杂质去除效果的影响,采用USTER AFIS单纤维测试仪对两种吸风形式、两种风量和三档除尘刀隔距条件下所加工的生条进行了棉结杂质的检测,结果表明:棉网清洁器采用单侧吸风,除尘刀隔距为0.53 mm时对棉结和杂质的去除效果最好;棉网清洁器采用双侧吸风时,当风量为160 m3/h,除尘刀隔距为0.53 mm时对棉结的去除效果最好,除尘刀隔距为0.46 mm时对杂质的去除效果最好;当风量为240 m3/h,除尘刀隔距为0.46 mm时对棉结和杂质的去除效果最好,生条中棉结和杂质的数量都比原棉时有明显减少.从总体趋势上看,单侧吸风方案对棉结和杂质的去除效果要好于双侧吸风方案.

Effect of Web Cleaner Mote Knife Gauge on Neps and Trash

To study the effect of web cleaner mote knife gauge on removing neps and trash in card sliver, USTER AFIS single fibre tester was adopted, neps and trash in card sliver that was produced in condition of two kinds of suction form, two kinds of air capacity and three kinds of mote knife gauge were tested. The result shows that when using unilateral suction and mote knife gauge is 0.53 mm, the effect of removing neps and trash is better. When using bilateral suction and air capacity is 160 m^3/h and mote knife gauge is 0.53 mm, effect of removing neps is better and mote knife gauge is 0.46 mm, effect of removing trash is better. When air capacity is 240 m^3/h and mote knife gauge is 0.46 mm, effect of removing neps and trash is better and number of neps and trash in card sliver is decreased sharply comparing to raw cotton. In general trend, neps and trash removal in unilateral suction program is better than that of bilateral suction program.
