Abstract
This application discloses a flame retardant, drapable, and substantially light impermeable fabric suitable for use as a curtain, window shade or the like comprising a tightly woven fiberglass fabric substrate which is coated on at least one surface thereof with one or more layers of a flame retardant foam coating composition. At least one of the foam coating layers is opaque and is comprised of a cured layer of flame retardant polymeric latex foam which renders the fabric substantially impermeable to light and is applied to the surface of the fiberglass substrate in an amount sufficient to make the fabric non-abrasive, abrasion resistant, and the coated fabric sewable and drapable.
Claims17
A flame retardant, drapable and substantially light impermeable fabric suitable for use as a curtain, window shade or the like comprising a tightly woven fiberglass fabric substrate which is coated on at least one surface thereof with one or more layers of a flame retardant foam coating composition, wherein at least one of the foam coating layers is opaque and is comprised of a cured layer of flame retardant polymeric latex foam;
- wherein the foam coating renders the fabric substantially impermeable to light and is applied to the surface of the fiberglass substrate in an amount sufficient to make the fabric non-abrasive, abrasion resistant, and the coated fabric sewable and drapable.
The fabric according to claim 8 wherein the face coat is comprised on a dry-weight basis and based on 100 parts of a foamable acrylic polymer, of about 25 to 75 parts filler, about 5 to about 25 parts plasticizer, and about 3 to about 10 parts antimony trioxide or antimony pentaoxide.
A flame retardant, drapable and substantially light impermeable fabric suitable for use as a curtain, window shade or the like comprising a tightly woven fiberglass fabric substrate which is coated on at least one surface thereof with one or more layers of a flame retardant foam coating composition, wherein at least one of the foam coating layers is opaque and is comprised of a cured layer of flame retardant polymeric latex foam;
- wherein the foam coating renders the fabric substantially impermeable to light and is applied to the surface of the fiberglass substrate in an amount sufficient to make the fabric non-abrasive, abrasion resistant, and the coated fabric sewable and drapable;
- and wherein the coating is comprised of at least three coating layers, wherein the innermost coating layer is white in color, the intermediate coating layer is grey or black in color and the outermost coating layer is white;
- wherein in each of the coating layers the pigment is dispersed in a coating composition comprised on a dry-weight basis of about 100 parts of a foamable polymer latex, and based on the weight of the polymer latex, about 2 to about 10 parts plasticizer, about 1 to about 10 parts flame retardant, about 10 to about 50 parts pigment, surfactant, about 25 to about 75 parts filler, and dispersant for the pigment.
A method for preparing a flame retardant, drapable and sewable fabric which does not transmit light comprising:
- A. coating a tightly woven fiberglass fabric substrate with at least one coating layer of an opaque foam coating composition comprised on a dry-weight basis of about 100 parts of a foamable polymer, about 2 to about 10 parts plasticizer, about 1 to about 10 parts flame retardant, about 5 to about 10 parts surfactant, about 10 to about 50 parts pigment, and dispersant for the pigment and thickener, the components of said composition being foamed with air;
- and then
- B. curing said foam coating to provide an opaque foam coating on said fiberglass base.
