HOLLOW FIBER FILM-KNITTING APPARATUS HAVING STATIC ELIMINATION MEANS

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber film-knitting apparatus having a static elimination means in which electrostatic charge of a hollow fiber film feeding and traveling as a weft is eliminated to stably feed the weft and static elimination is carried out during knitting operation by a knitting machine and trouble caused by electrostatic charge can be solved. SOLUTION: The hollow yarn film 3 pulled out from a weft bobbin 1 is fed by a feed roller 6 and introduced into an air dancer part B while feeding a static elimination ion to the hollow fiber film by a first static elimination means 9. The hollow yarn film 3 carries out raising traveling by air stream from either one nozzle 14 and the hollow yarn film 3 carries out lowering traveling against air stream from the other nozzle 15 to nearly describe a parabola in the air dancer part B. The electrostatic charge-removing ion is fed to the hollow yarn film 3 lowered and traveled from the air dancer part by a second static elimination means 20 and the hollow yarn film 3 is fed through a guide 21 having a spring to a traverse guide 32 of a knitting machine C while carrying out static elimination and is knitted by warp 41. A knitting operation is carried out under the atmosphere of static elimination ions by those fed from a third static elimination means 26. COPYRIGHT: (C)2004,JPO&NCIPI
