MULTI-FILAMENT SPLIT-YARN SHEET, AND METHOD AND DEVICE FOR THE MANUFACTURE THEREOF

Document Type and Number:

WIPO Patent Application WO/1997/041285

Kind Code:

A1

Abstract:

A method for manufacturing a good-quality split-yarn sheet by extending individual filaments of a multi-filament so that they are parallel to each other in a state free from any quality degradation; a device to be used in the above method; and a split-yarn sheet made thereby. The multi-filament is controlled to be in a specified overfeed state and fed from the fiber supply section to the take-up section. An air flow is supplied across the multi-filament to split the filaments making up the multi-filament in the widthwise direction to form a desired split-yarn sheet. With this method and device, it is possible to produce a desired form of split-yarn sheet.
