Factors restricting the qualification rate of E-glass rovings;
制约无碱玻璃纤维无捻粗纱合格率的因素分析
Some problems found in roving production in some factories,such as inconsistency of roving tension,missing ends in rovings and roving splicing problem,are analyzed.
分析了无捻粗纱生产厂家在生产中存在的一些问题,如纱线张力一致性问题、纱线缺股问题、纱线接头问题,针对生产中存在的这些问题进行技术改进,并介绍了3种设备即张力器、断纱自停装置、空气捻接器等新技术在合股无捻粗纱生产中的应用及技术改进。
Through the tests on the stiffness of glass rovings after conditioning for different time,at different ambient temperature and at different relative humidity,the main factors affecting the roving stiffness were investigated,thus providing basis for enacting relative standards of testing methods.
通过对玻璃纤维无捻粗纱经不同的调湿时间,不同的环境温度和不同的相对湿度调湿后硬挺度的试验,分析了影响玻璃纤维无捻粗纱硬挺度的主要因素,为制订相关的试验方法标准提供了依据。
