    Abstract: A self-bonded nonwoven web, at least some cellulosic fibers that are self-bonded to each other at points of intersection of the cellulosic fibers with each other; and, an ionic liquid. Methods of making such a web are also disclosed, wherein the method comprises: contacting at least some of the first, cellulosic fibers with an ionic liquid; exposing the ionic liquid and the first, cellulosic fibers to a first temperature; and exposing the ionic liquid and the first, cellulosic fibers to a second temperature that is lower than the first temperature.

    Abstract: 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.

    Abstract: A spunbond method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse prepared bio-polyamide 6,10 into a melt via spunbond method, next extrude and spun and draw the melt to form filaments, then bond and lay the filaments on a conveyer to form a substrate fibrous web of bio-polyamide 6,10. Secondly, blend and dissolve prepared pulp by putting N-methylmorpholine N-oxide (NMMO) dissolving solvent, then dehydrate it to form dope, then extrude the dope out by an extruder with external compressed quenching air for converting it into cellulose filaments, then draw, bond and overlay the cellulose filaments to become uniform natural cellulose filaments on existing substrate fibrous web previously to form an overlaid fibrous web in the conveyer. Finally, coagulate, regenerate and convert the fibrous composite of the bio-polyamide 6,10 and natural cellulose into nonwoven fabric with hygroscopic metastatic feature by orderly applying hydro-entangled needle punching, drying, winding-up processes.

    Abstract: According to one aspect of the present disclosure, a mechanism and method is provided to clean and remove or separate cellulose fibers from the source fibrous material without stressing and/or damaging the cellulose fibers. The mechanism includes an agitator that directs the washing fluid in a vertical direction into engagement with the fibrous material to effect maximum cleaning of the cellulose from the remainder of the fibrous material without damaging or stressing the cellulose, thereby providing cellulose that can enhance the strength and other beneficial characteristics of a biocomposite material formed using the cellulose.
