Nonwoven cellulose fiber fabric with homogeneously merged fibers
A nonwoven cellulose fiber fabric, in particular directly manufactured from lyocell spinning solution, wherein the fabric comprises a network of substantially endless fibers, and wherein the fibers are homogeneously merged substantially over the entire fabric.
Man-made cellulosic fiber and nonwoven product or fabric comprising the cellulosic fiber
The present invention relates to a modified cellulosic fiber that comprises anionic moieties in an amount of more than 0.25 mol/kg of dry fiber and has applied thereon a polymeric modifying agent in an amount of from 0.5 wt. % to 5.0 wt. %, based on dry fiber, the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5 meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fiber is in the range of from 1:1 to 25:1. The fiber according to the present invention is characterized in that the anionic moieties are incorporated in the fiber and are from carboxymethylcellulose, and that the polymeric modifying agent comprising cationic moieties is selected from the group consisting of polydiallyldimethylammonium chloride (poly-DADMAC), poly(acrylamide-co-diallyldimethylammonium chloride) (PAM-DADMAC) and mixtures thereof. The invention furthermore relates to a nonwoven product or fabric comprising the modified cellulosic fiber.

CU-CONTAINING NON-WOVEN FABRIC AND METHOD FOR PREPARING THE SAME
This application provides a Cu-containing non-woven fabric with antibacterial and antiviral properties and application thereof. The preparation method includes the following steps: web-forming, pre-wetting, and spunlace bonding a fiber in sequence to obtain the spunlace non-woven base fabric; padding and sizing the spunlace non-woven base fabric in an organic copper complex solution to obtain a Cu-containing spunlace non-woven fabric, wherein the Cu-containing spunlace non-woven fabric contains copper of ≥500 ppm; and drying and winding the Cu-containing spunlace non-woven fabric after being padded and sized. The method is simple and easy to achieve industrialization. This application also provides a Cu-containing non-woven fabric with antibacterial and antiviral properties having excellent antibacterial and antivirus properties. This application also provides an application of the Cu-containing non-woven fabric with antibacterial and antiviral properties which has an advantage of being widely used.
