喷气涡流纺涡流管喷孔工艺的实验研究

喷气涡流纺是利用高速旋转气流在涡流管中对纤维加捻而使其成纱,为了研究涡流管喷孔参数对纺纱的影响,对涡流管的喷孔参数(喷孔孔径、喷孔角度和喷孔个数)进行探讨,选择2种喷孔直径(0.5、0.6 mm),并在这2种直径下选择7种喷孔角度(30.0°、32.5°、35.0°、37.5°、40.0°、45.0°、50.0°)、3种喷孔个数(4、5、6),以粘胶为原料在喷气涡流纺纱小样机上进行纺纱实验,结果表明:当喷孔角度为45.0°,喷孔直径为0.5 mm,喷孔数目为4时,成纱质量好且能耗小.

Experiment research of vortex tube’s jet orifice technology in jet vortex spinning

It is well known that jet vortex yarn is formed by high speed air vortex in vortex tube to entangle the fibers. In order to study the influence of the vortex tube’s jet orifice parameters on the spinning, the vortex tube’s jet orifice parameters (jet orifice diameter, jet orifice obliquity, jet orifice number) were discussed. The two jet orifice diameters (0.5 mm, 0.6 mm) were chosen, seven jet orifice obliquities (30.0°, 32.5°, 35.0°, 37.5°, 40.0°, 45.0°, 50.0°), three jet orifice numbers (4, 5, 6) were selected based on the two diameters, with viscose as raw material for spinning experiments in small sample machine of jet vortex spinning, experimental results indicate that: the quality of the yarn is good and the energy consumption is small under the condition of jet orifice obliquity is 45.0°, jet orifice diameter is 0.5mm, jet orifice number is 4.
