【摘要】 研究探明了影响机制丝绵开绵品质的主要因素有钢针长度、茧盖和蛹衬的存在等,设计了压绵软辊及截绵针排,用以减少绵坯中未被拉开绵团的数量。试验结果表明:使用3组压绵软辊,直径80mm,转速450r/min,可使钢针针头保持裸露3~4mm,有利于穿刺绵层和提高单张绵质量,与针排配合,可使绵坯中未被拉开绵团由10个/m2减少至1~2个/m2,显著改善了开绵品质。更多还原

【Abstract】 In this study, we found that the main influence factors on the quality of the floss silk were the length of pin, the cocoon shell and wadding of pupa, then designed the soft press roller and gill faller to reduce the silk tops. The results showed that the 3 soft press rollers with 80 mm in diameter and 450 r/min in speed could keep 3-4 mm length of pin out of the floss in order to puncture the floss layer and increase the weight of the single floss. When the soft press roller worked together with the gill faller, the silk tops of the floss could be reduced from 10 piece/m2 to 1-2 piece/m2.更多还原
