3.
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。
2) worsted rubbing frame
无捻粗纱机
1.
This paper introduced the development direction of the modern worsted rubbing frame.
介绍了F2461型无捻粗纱机的机架、传动、牵伸、搓板等主要机构的特点,以及自动落纱机构的自动化控制装置和全自动落纱升头方式。
3) direct roving
直接无捻粗纱
1.
The definition of winding ratio,the forming process of direct roving cakes,the setting of winding ratio and its influence on cake forming are described.
介绍了卷绕比定义,直接无捻粗纱丝饼成形过程,卷绕比的设定,对丝饼成形的影响,得出结论:卷绕比的选择与丝束的tex值之间的关系较大,高tex的丝饼宜选用较小的卷绕比值,低tex的丝饼宜选用较大一些的卷绕比:丝饼成形还受拉丝设备工艺等影响,且卷绕过程中,一个细小差别可能会引起较大变化。
2.
