Abstract

Light resistance of polypropylene (PP) and nylon 6 fabrics, grafted with acrylic acid and then treated with aqueous solutions of some metallic salts or tris (1-aziridinyl) phosphine oxid (APO), was studied by evaluating the retention of warp tensile strength of the fabrics after exposure to xenon arc lamp or sunlight.<br>Larger loss in strength of original untreated PP fabric after exposure as a result of the extraction with benzen may be explained by the removal of included stabilizer by the extraction.<br>Grafting of acrylic acid onto PP fabric and further treatment with aqueous solution of metallic salts cause unfavorable effect on light resistance due to the presence of carbonyl groups in the grafted side chains.<br>The most effective method to improve the light resistance of acrylic acid grafted PP fabrics is the after-treatment with APO. The higher the percent grafting or/and concentration of APO treating solution the better resistance is attained.<br>On nylon 6 fabric, nearly similar results to the case of PP fabric are obtained by grafting and treating with metallic salts, but the effect of APO is not crear with acrylic acid grafted nylon 6 fabrics as the add-on of APO is not so high as the case of acrylic acid grafted PP fabrics.
