A coated and varnished membrane, the membrane including at least one fabric having at least one face coated with at least one layer of polyvinyl chloride, and at least one varnish film on the coated face of the membrane, the varnish film including a polymeric binder and a mineral matrix in powder form including silver particles. A method for producing a membrane according to the invention. A use of a membrane according to the invention as a virucide.

A flame retardant aid includes an amphoteric polymer compound having at least one of a specific cationic unit such as allylamine, and an anionic unit such as maleic acid, and a flame retarding agent composition including the flame retardant aid. A method of producing a flame-retardant fiber fabric includes treating a polyester fiber fabric using a flame retardant aid including a flame retardant component and the above amphoteric polymer compound, and drying the polyester fiber fabric.

The invention comprises a method. The method comprises applying a composition to a tufted primary backing material, wherein the primary backing material has a first primary surface and a second primary surface, wherein tufts extend outwardly from the first primary surface and loop backs are formed on the second primary surface, and wherein the composition is applied to the loop backs and second primary surface of the tufted primary backing material. The composition comprises an aqueous polymer dispersion of colloidal thermosetting polymer particles or colloidal thermoplastic polymer particles and second thermoplastic polymer particles dispersed in the water, wherein the second thermoplastic polymer particles have an average particle size of approximately 200 micron to approximately 1,000 microns. The method further comprises heating the tufted primary backing material and aqueous polymer dispersion to remove water therefrom. A novel adhesive composition is also disclosed.

A carpet for a sound reduction material is disclosed including: a non-permeable primary coating layer formed of polyethylene (PE) resin, being in contact with a lower surface of a fabric layer and having a basis weight of 200 to 300 g/m.sup.2; a permeable felt layer in contact with a lower surface of the primary coating layer and having a basis weight of 200 to 500 g/m.sup.2; and a non-permeable secondary coating layer formed of polyethylene (PE) resin or ethylene vinyl acetate (EVA), being in contact with a lower surface of the felt layer and having a basis weight of 200 to 1,000 g/m.sup.2. The carpet for a sound reduction material may thus have improved noise, vibration and harshness (NVH) performance, reduced total weight and improved stiffness.
