Stapled melt spinning method for producing non-woven fabrics with hygroscopic metastatic feature
A stapled melt spinning method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse bio-polyamide 6,10 into melt, extrude and spin it out spin heads of extruder into filaments, cool, draw and collect filaments into tow, then extend, cut and card the filaments into the staples, and spread the staples on a conveyer to form fibrous web. Next, blend and dissolve pulp by N-methylmorpholine N-oxide (NMMO) dissolving solvent, dehydrate it to form dope, and extrude and spin it out spin heads of extruder into filaments, then cool, draw and collect filaments into tow, and extend, cut and card filaments into staples, then overlay the staples over existing fibrous web to form a composite fibrous web of bio-polyamide 6,10 and cellulose filaments. Finally, coagulate, regenerate and convert fibrous composite of bio-polyamide 6,10 and natural cellulose into nonwoven fabric with hygroscopic metastatic feature by hydro-entangled needle punching, drying, winding-up processes.
Methods for the fabrication of polymeric fibers
In accordance with an exemplary embodiment, a method is provided for forming a micron, submicron and/or nanometer dimension polymeric fiber. The method includes providing a stationary deposit of a polymer. The method also includes contacting a surface of the polymer to impart sufficient force in order to decouple a portion of the polymer from the contact and to fling the portion of the polymer away from the contact and from the deposit of the polymer, thereby forming a micron, submicron and/or nanometer dimension polymeric fiber.
ULTRAFINE FIBER PRODUCTION METHOD AND PRODUCTION DEVICE
An ultrafine fiber production device has a first heating unit, a nozzle unit, a hot air heating unit, a hot air blowing unit, a second heating unit, and a fiber collecting unit. The first heating unit melts a thermoplastic resin. The nozzle unit discharges the thermoplastic resin melted by the first heating unit. The hot air blowing unit performs fiber forming by blowing high-temperature gas produced by the hot air heating unit to the melted thermoplastic resin discharged by the nozzle unit and by extending the thermoplastic resin. The second heating unit further heats, extends, and fines produced fibers. The fiber collecting unit collects the thermoplastic resin in a fibrous form which is fined by the second heating unit.
METHOD OF MAKING UNIFORM SPUNBOND FILAMENT NONWOVEN WEBS
A method of making nonwoven webs comprising providing a spinneret wherein the spinneret includes a pattern of conduits, the pattern of conduits forming an extrusion region; directing only a first stream of molten propylene polymer having a first temperature into a region adjacent of the first side of the spinneret, directing only a second stream of molten propylene polymer having a second temperature into a region distal to the first side of the spinneret, extruding only the first stream of molten propylene polymer through the exit openings in a first zone; extruding only the second stream of molten propylene polymer through the exit openings of a second zone; the second zone is distal to the first side with the first zone being between the second zone and the first side.
