Abstract

The invention relates to a sectional membrane filamentation friction composite spinning method, and belongs to the technical field of textiles. A membrane cutting traction device is arranged above a front roller jaw of each traction mechanism of a friction yarn machine; a cutting region is formed between a cutting-resistant ring and a cutting roller of a membrane putting cutting device; uniform laid and spread belt-shaped multifilaments are formed through cutting; the sectional membrane is filamented; a conventional spinneret orifice linear jetting filamentation method is changed; the multifilaments are tracked through a first traction region and a second traction region; the filament intensity in the multifilaments is enhanced; thinned multifilaments and short fiber strips pass through a carding region of a friction spinning machine to be carded into composite fiber flows with mixed sectioned nanometer and micron filament strips and short fiber strips; the composite fiber flows enter a position between the friction rollers through a fiber conveying passage to be twisted into fine tex friction composite yarns with the uniformly held nanometer and micron filament strips and short fiber; the difficult problem that filament yarns, nanometer fiber and conventional short fiber cannot be uniformly mixed and cannot be sufficiently held during the friction composite spinning are solved; the membrane industry and the textile industry are merged. The operation is convenient; the popularization is easy.

Description

technical field [0001] The invention relates to a friction composite spinning method for film-filamentization, which belongs to the technical field of textiles. Background technique [0002] Textile fibers can be divided into natural fibers and chemical fibers according to their sources; chemical fibers generally include recycled fibers and synthetic fibers. Among them, man-made fibers refer to natural polymers that originally existed in nature. Because the length and thickness of the macro-aggregated form cannot meet the requirements of textile processing, it needs to be re-assembled by chemical methods to form fibers to meet the requirements of textile processing. Such as regenerated cellulose fibers, various viscose fibers, etc.; synthetic fibers refer to petrochemical small molecules as raw materials, chemically synthesized polymers, and then processed into chemical filaments through spinning processes. The production of chemical filaments can be divided into melt spinn...
