Document Type and Number:
WIPO Patent Application WO/2022/104644
Kind Code:
A1
Abstract:
A method for manufacturing a composite fiber article, wherein the composite fiber article (1) has composite chemical fibers (11), and raw materials for preparing the composite chemical fibers (11) include: an elastic plastic (12) and a thermoplastic plastic (13). The elastic plastic (12) and the thermoplastic plastic (13) are respectively melted by means of heating and are brought into a die head (2), wherein the die head (2) has a main die channel (21) for extruding the elastic plastic (12) into fibers; the main die channel (21) is provided, on a lateral side, with a branched secondary die channel (22); and the secondary die channel (22) is configured for the thermoplastic plastic (13) to flow toward and bind to a lateral side of the elastic plastic (12) and then undergo extrusion into the composite chemical fibers (11) through the main die channel (21). In addition, after the composite fiber article (1) is stretched, the thermoplastic plastic (13) extends and warps on a lateral side of the elastic plastic (12), such that the composite fiber article (1) becomes fluffy.
