向下拉

A device and method for preparing compound nano fiber endless tow, which contains feeding material liquid to pair of electric spinning nozzle on frame, each nozzle respectively applied with high dc voltage with opposite polarity, each pair of nozzle jetting out nano fiber with opposite electric charge, said nano fiber attracting and colliding each other to form compound nano fiber, then forming nano fiber endless tow after drawing and stretching, the first opposite set pair of electric spinning nozzle jetted compound nano fiber endless tow is stretched down and used as acceptor which covered by the nano fiber jetted by second pair of nozzle an d forming two layers of compound nano fiber endless tow after drawing and stretching, in turn to get multilayer compound nano fiber endless tow after drawing and stretching by godet roller.

复合纳米纤维长丝束制备装置及其制备方法是一种简单、高效电纺制备纳米纤维长丝束的方法，其步骤为将料液输送给支架(3)上的电纺喷头对(1)；喷口相向的电纺喷头对(1)的每个喷头分别施加相反极性的直流高电压；每对相向喷口喷出分别带相反电荷的纳米纤维，并在空中相互吸引、碰撞形成复合纳米纤维，经牵引、拉伸后形成复合纳米纤维长丝束；第一对相向放置的电纺喷头纺丝形成的复合纳米纤维长丝束向下拉伸，并作为接受体与第二对电纺喷头喷出的分别带相反电荷并相互吸引的纳米纤维在空中相遇，被第二对电纺喷头喷出的纳米纤维包裹，经牵引、拉伸后形成两层复合纳米纤维长丝束；依次类推，最后经导丝辊对(2)牵引、拉伸后得到多层复合纳米纤维长丝束。
