Modification of bentonite nanoclay for textile application

The influence of the bentonite content (1, 3, 5 wt%) on mechanical properties lightweightcotton (C), polyester (P) and polyester-cotton (P/C 50/50) fabrics was investigated. Starch used asa water-insoluble binder for coating fabrics. Bentonite nanoparticles were obtained by repeated hydration,decantation evaporation water dispersion. particle size determinedby XRD method using Debye-Scherrer equation. diffraction laser beam todetermine particles distribution. addition nanoclay significantly improved tensilestrength (26-61% 99–118% in warp weft direction, respectively) tear strength (4‒13%and 5–24% wrap coated Their abrasion resistancehas also slightly increased. biggest changes noted cotton fabric, smallest thepolyester which may result from low compatibility between starch fabric.
