将粗纱引入膨化机中，在压缩空气气流作用下将粗纱打散膨化，然后再将膨化后的粗纱重新绕成纱团。
The roving is introduced to the texturizing machine(air jet), which breaks the surface fibers at random under the effect of compressed air. That gives the roving a bulkier appearance. Then, the texturized roving is wound into a bobbin.
无碱玻璃纤维膨体纱
Texturizied Roving
具有膨化均匀、吸附能力强等特点，适用于增强酚醛树脂、环氧树脂和不饱和聚酯树脂等。
Texturized Roving is compatible with PF, EP, and UP resins. It features uniform texturizing and high absorbability.
