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.

The present invention relates to a formed fabric which contains cellulose fibers, which contain zinc oxide particles which are at least partially incorporated and which is additionally impregnated with a liquid, and to a method of its production and to its use, in particular for manufacturing preservative-free, moist wet wipes.

The present invention relates to fibrillated lyocell fibers which have a fibrillation ratio Q of 20 or more and whose content of microfibers with a fineness of less than 14 mesh and a diameter of less than 2 μm is at least 50%, as well as the use thereof for producing a wipe, which contains cellulosic fibers and 5 to 20 wt. % of fibrillated lyocell fibers.

A cellulosic fiber includes a fiber body including a cellulosic material and non-encapsulated phase change material dispersed within the cellulosic material. The non-encapsulated phase change material forms a plurality of distinct domains dispersed within the cellulosic material. The non-encapsulated phase change material has a latent heat of at least 40 Joules per gram and the cellulosic fiber has a latent heat between 9.8 Joules per gram and 132 Joules per gram and a transition temperature in the range of 0° C. to 100° C., and cellulosic fiber provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature.

An object of the present invention is to provide a salt water thickener that uniformly (favorably) disperses ultrafine cellulose fibers even in a liquid containing a salt (electrolyte). The salt water thickener comprises ultrafine cellulose fibers and a water-soluble polymer and can thereby uniformly disperse the ultrafine cellulose fibers even in a liquid containing a salt. The salt water thickener of the present invention is uniformly dispersed even in a liquid containing a salt and therefore exerts a high viscosity. The salt water thickener of the present invention can also be used as an additive for a fluid. The salt water thickener of the present invention can be used for purposes, for example, subterranean formation processing.

The invention relates to a Lyocell fiber with recycled cellulose, which uses recycled cellulose pulp to dissolve in the spinning solution. The weight percentage of the recycled cellulose in the spinning solution is 30% to 55%. The Lyocell fibers of the invention also have hydrophilic, cooling, drape, antistatic, and biodegradable properties compared to the Lyocell fibers without recycled cellulose.

The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).
