Absorption and Permeability of Air-jet Textured Glass Fiber Yarn and Its Fabric for Resin

The Absorption and permeability of air-jet textured glass fiber yarn and its fabric and bonded tenacity of the fabric have been studied in relation to the main parameters, air supplied pressure and overfeed ratio.It has been observed that increasing the level of main parameters improves the coated ratio of the textured yarn and its fabric as well as the bonded tenacity of the fabric made of textured yarn. Comparison of absorption or permeability between textured and supplied yarns, and comparison of absorption or permeability and bonded tenacity between the two kinds of fabrics have been elucidated.

聚酰胺56 POY纤维的开发

PA56纤维不仅具有PA66的优良性能,还有吸湿性好和阻燃等特点,具有良好的应用前景。PA56的热膨胀系数、结晶度、玻璃化温度、熔融温度等均低于PA66,因此在进行纺丝定形时应控制好相关参数,文章通过生产实践对此进行了详细说明。
