发明名称 Flame retardant dryer fabrics
摘要 The present invention is directed at modifying a resin-treated dryer fabric in such a way that its scaffolding effect is reduced or eliminated. Further, according to the teachings of the present invention, the resin used to coat the dryer fabric is itself made self-extinguishing, such that even if the fabric acts as a scaffold, the resin will not burn. Even further, a degree of flame retardancy is imparted to the base fabric in those cases where the base fabric itself is not self-extinguishing. A dryer fabric in which the woven fabric material is treated with an admixture of flame retardant material and resin, such that the flame retardant and resin are added to either the yarns of the fabric or the woven fabric at the same time. The admixture may take the form of a solution, a suspension, a colloidal suspension, a dispersion or an emulsion of flame retardant material and resin. The flame retardant material is preferably a water soluble material having an active phosphorous ingredient, preferably at the 15% level. The retardant material, in some cases, can also be a high bromide content material.
