Development of some functional properties on viscose fabrics using nano kaolin

Nanoclays are among the more important industrial minerals. They are inexpensive, widely available in nature, and environment friendly. Nano kaolin (NK) is used to impart additional values of viscose fabrics. The mentioned fabrics were treated with different concentrations of NK using pad-dry cure technique. The surface morphology and surface chemical elements of treated as well as untreated fabrics were investigated using scanning electron microscopy and dispersive X-ray spectroscopy, respectively. Tensile strength and elongation, thickness, bending length, moisture regain and antimicrobial activity of the treated fabrics were evaluated. New colouring material (Thiazolidin), direct and reactive dyes were used for dyeing the treated and untreated fabrics. K/S and washing fastness of the dyed fabrics were assessed and statistically compared using t test. The effect of treatment and dying on performance properties of garments were evaluated by calculating quality factor for each fabric.
