竹浆纤维毛巾纱的生产实践

为纺制竹浆纤维毛巾纱,针对竹浆纤维特点,通过开清棉控制打手速度,减少纤维损伤;梳棉合理配置针布及梳理工艺,改善棉网清晰度;并条合理配置牵伸工艺,采用炭黑防缠胶辊;粗纱采用较大捻系数,严格筛查假捻器,控制伸长;细纱合理配置牵伸隔距,采用软胶辊,控制好温湿度;络筒控制气圈张力,减少脱圈,正确设定清纱参数等工艺技术措施,顺利纺制出竹浆纤维18.5 tex纱,满足了毛巾用纱质量要求。

Production of Bamboo Fiber Towel Yarn

To spinning bamboo fiber towel yarn,according to bamboo fiber property,in opening and picking process,beater speed was controlled to reduce fiber injury.In carding process,card clothing and carding processing were configured rationally to improve cotton web definition.In drawing process,draft process was selected properly and carbon black anti-winding rubber-covered roll was adopted.Larger twist factor was adopted in roving process,false-twist device was selected strictly and elongation was controlled well.In spinning process,draft gauge was selected rationally,soft rubber-covered roll was adopted,temperature & humidity were controlled well.In winding process,balloon tension was controlled,coil slippage was reduced,electronic yarn clearer parameter was selected correctly,finally bamboo 18.5 tex yarn can be spun successfully,the quality can reach towel yarn demands.
