Abstract

Cotton fabrics is a kind of widely used but easily ignited textile fibers. In order to improve its flame retardant, an eco-friendly and simple method is proposed. Different amounts of coatings containing phosphoguanidine (PHO), ATMP and alginate (AL) were assembled on cotton fabric surface by layer-by-layer (LbL) technique. FTIR spectra indicated that the LbL coating was successfully deposited on the surface of cotton fabric. Char residue of TGA over 20wt% indicated the performance of the thermal stability for all treated samples had significantly increased. From the MCC test, the peak heat release rate (PHRR) showed a obviously decrease of over 50% and and the achievement of the coated samples in a self-extinguished level from vertical combustion test. All these results demonstrated that the PHO/ATMP /AL-coated cotton fabrics had excellent flame retardancy and revealed the importance of PHO/ATMP /AL coating in enhancing the flame retardancy for cotton fabrics.
