Methods and compositions for sustainable textile materials

Abstract

In one aspect, the disclosure relates to compositions that can have improved thermal management properties, UV-absorbing properties, anti-bacterial properties, and/or fire-resistance properties that utilize sustainable materials and can be used to fabricate filaments, yarns, fabrics, and artificial leather. The disclosed compositions can comprise a boron nitride nanomaterial and a cellulose nanomaterial. The disclosed compositions can also comprise a boron nitride nanomaterial, a cellulose nanomaterial, and an alginate material. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

What is claimed is:

         2 . The composition of  claim 1 , wherein the boron nitride nanosheets have an average thickness of from about 1 nm to about 50 nm. 
     
     
         3 . The composition of  claim 1 , wherein the cellulose nanomaterial comprises cellulose nanofibers having an average diameter of less than about 500 nm. 
     
     
         4 . The composition of  claim 1 , wherein the cellulose nanomaterial comprises cellulose nanocrystals having an average particle size of less than about 500 nm in the longest dimension. 
     
     
         5 . The composition of  claim 1 , wherein the boron nitride nanomaterial and the cellulose nanomaterial are present in a weight ratio of from about 5:1 to about 1:5. 
     
     
         6 . The composition of  claim 1 , wherein the composition further comprises a component selected from an acid-based coagulant, an electrolyte coagulant, a plasticizer, a lipid, and combinations thereof. 
     
     
         7 . The composition of  claim 6 , wherein the plasticizer is an epoxidized soybean oil, castor oil, cardanol, citrate or derivative thereof, succinate or derivative thereof, isosorbide, glycerol, or combinations thereof. 
     
     
         8 . The composition of  claim 6 , wherein the acid-based coagulant comprises citric acid. 
     
     
         9 . The composition of  claim 6 , wherein the electrolyte coagulant comprises a cationic polymer. 
     
     
         10 . The composition of  claim 9 , wherein the cationic polymer comprises chitosan. 
     
     
         11 . The composition of  claim 6 , wherein the lipid comprises cottonseed oil, sunflower oil, linseed oil, beeswax, or combinations thereof. 
     
     
         12 . The composition of  6 , wherein the plasticizer is present in an amount from about 0.1 wt % to about 50% based on the dry mass of the composition. 
     
     
         13 . A filament comprising the composition of  claim 1 . 
     
     
         14 . A yarn comprising the filament of claim  16 . 
     
     
         15 . The yarn of  claim 14 , further comprising another type of filament to form a blended yarn. 
     
     
         16 . An article comprising the filament of claim  16 . 
     
     
         17 . A film, a sheet, a cast material, or a molded material comprising the composition of  claim 1 . 
     
     
         18 . An article comprising the film, the sheet, the cast material, or the molded material of  claim 17 .
