Abstract

A fibrous monofilament includes plant pulp fibers and the fibrous monofilament includes at least 30 wt % of plant based natural cellulose fibers.

Claims

exact text as granted — not AI-modified
1 . A fibrous monofilament of a diameter of 20-400 μm, comprising at least 30 wt % of plant based natural cellulose fibers, wherein the plant based natural cellulose fibers are non-regenerated. 
     
     
         2 . The fibrous monofilament according to  claim 1 , further comprising man-made cellulosic fibers, containing between 1 and 50 wt. % of man-made cellulosic fibers, or between 1 and 30 wt % of man-made cellulosic fibers, or between 1 and 20 wt % of man-made cellulosic fibers. 
     
     
         3 . The fibrous monofilament according to  claim 1 , further comprising man-made cellulosic Lyocell fibers, containing between 1 and 50 wt. % of man-made cellulosic Lyocell fibers, or between 1 and 30 wt % of man-made cellulosic Lyocell fibers, or between 1 and 20 wt % of man-made cellulosic Lyocell fibers. 
     
     
         4 . The fibrous monofilament according to  claim 1 , further comprising recycled textile waste fibers, containing from 1 to 50 wt % of recycled textile waste fibers, or between 30 to 50 wt % of recycled textile waste fibers, or between 40 and 50 wt. % of recycled textile waste fibers. 
     
     
         5 . The fibrous monofilament according to  claim 4 , wherein the recycled textile waste fibers comprise thermobonding fibers. 
     
     
         6 . The fibrous monofilament according to  claim 1 , further comprising recycled textile waste fibers from pre-consumer textile waste, containing from 1 to 50 wt % of recycled pre-consumer textile waste fibers, or between 30 to 50 wt % of recycled pre-consumer textile waste fibers, or between 40 and 50 wt % of recycled pre-consumer textile waste fibers, such recycled pre-consumer textile waste fibers being prepared according to a process for pretreating reclaimed cotton fibers, wherein the pretreatment of the reclaimed cotton fibers includes a metal removing stage and an oxidative bleaching stage. 
     
     
         7 . The fibrous monofilament according to  claim 1 , wherein the man-made cellulosic fibers have a length between 1 and 10 mm, or between 2 and 10 mm, or between 4 and 6 mm; and/or yarn count between 0.7 and 7 dtex, or between 0.9 and 1.7 dtex. 
     
     
         8 . The fibrous monofilament according to  claim 1 , wherein the fibrous monofilament comprises between 30 and 99 wt. %, or between 50 and 99 wt. %, or between 70 and 99 wt. % of the plant based natural cellulose fibers. 
     
     
         9 . The fibrous monofilament according to  claim 1 , wherein the plant based natural cellulose fibers are mechanically and chemically interlinked to each other. 
     
     
         10 . The fibrous monofilament according  claim 1 , wherein the plant based natural cellulose fibers originate from chemical pulp, thermomechanical pulp, mechanical pulp or waste paper pulp. 
     
     
         11 . The fibrous monofilament according to  claim 1 , wherein the monofilament further comprises from 0.01 to 30 wt. % of additives, or from 0.05 to 20 wt % of additives, or from 0.1 to 15 wt % of additives. 
     
     
         12 . The fibrous monofilament according to  claim 11 , wherein the additives include at least one of the following: alginate, alginic acid, pectin, carrageenan, carboxymethyl cellulose, starch, polyacrylamides, nanocellulose and resins like vinyl acetate. 
     
     
         13 . The fibrous monofilament according to  claim 11 , wherein the fibrous monofilament comprises additives including thermoplastic fibers. 
     
     
         14 . The fibrous monofilament according to  claim 1 , wherein the fibrous monofilament comprises density between 800 and 1700 kg/m 3 . 
     
     
         15 . The fibrous monofilament according to  claim 1 , comprising linear mass density of 5-100 grams per 1000 meters, being 5-100 tex. 
     
     
         16 . The fibrous monofilament according to  claim 1 , comprising tenacity of 5-25 cN/tex, when measured according to ASTM D5035. 
     
     
         17 . The fibrous monofilament according to  claim 5 , wherein the thermobonding fibers comprise at least one of polypropylene, polyamide, polyester, polypropylene/polyester and bi-component short cut fibers. 
     
     
         18 . The fibrous monofilament according to  claim 9 , wherein the chemical interlinking is provided by hydrogen bonds between the plant based natural cellulose fibers. 
     
     
         19 . The fibrous monofilament of  claim 13 , wherein the thermoplastic fibers comprise at least one of the following: polypropylene, polyamide, polyester, polypropylene/polyester and bi-component short cut fibers. 
     
     
         20 . The fibrous monofilament according to  claim 1  comprising linear mass density of 5-50 tex.
