粗细皆宜的Nanoval裂丝纺丝技术

Nanoval splitspinning-from coarse to nano

化学纤维纺丝时,纤维拉细过程主要是,在纤维末端通过导丝轮以及卷绕筒管在机械拉伸力的作用下或者在纤维表面通过纺粘、熔喷工艺在空气动力的作用下将其沿纵向拉伸完成。Nanoval的纤维成型技术与此完全不同,主要是通过将液流分裂细化并冷却成多根细单丝,单丝数目可以在连续的情况下多达数百根。

Synthetic or chemical fiber spinning reduces a fiber forming material by drawing it longitudinally to filaments by mechanical draw forces applied at their ends through godets, bobbins winding them up or at their skin by aerodynamic forces spunbond, meltblown. Nanoval differs fully from this method as filaments are formed by splitting a liquid stream under attenuation and quenching it into a multitude of finer filaments, at most continuous, its number can be up to several hundreds from one monofilament.
