Textile products having flame retardant properties and methods of manufacture
View Patent ↗A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material having a primary layer or backing with intumescent particles coated, sprayed, sprinkled, or otherwise applied to the upper surface thereof. Additionally or alternatively, the particles may be incorporated into the tufting primary or backing. The intumescent particles may also be complexed with additional agents, such as antimicrobial agents, softening agents, pliability agent, stain resistant agents, waterproofing agents, static resistance agents and combinations thereof.
1. A flame retardant carpet, comprising:
(1) a primary backing capable of being tufted having an upper surface for receiving a carpet material and a lower surface, the primary backing comprising intumescent material coated on or applied to the upper surface only, incorporated into the primary backing only, or both;
(2) carpet fibers tufted on the upper surface of the primary backing; and
(3) a backcoating associated with the lower surface of the primary backing.
2. The flame retardant carpet of claim 1 , wherein the intumescent material is coated, screen printed, dotted, sprayed, sprinkled, soaked, layered, applied to the upper surface, or a combination thereof.
3. The flame retardant carpet of claim 1 , wherein the intumescent material comprises an acrylic binder, ammonium phosphate, melamine (2,4,6-triamino-1,3,5-trizine), water, aluminum trihydrate, and melamine-formaldehyde resin.
4. The flame retardant carpet of claim 3 , wherein the intumescent material comprises:
(a) about 10-30% acrylic binder;
(b) about 15-35% ammonium phosphate;
(c) about 5-20% melamine (2,4,6-triamino-1,3,5-trizine);
(d) about 10-30% water;
(e) about 15-35% aluminum trihydrate; and
(f) about 1-15% melamine-formaldehyde resin.
5. The flame retardant carpet of claim 4 , wherein the intumescent material comprises:
(a) about 20% acrylic binder;
(b) about 24% ammonium phosphate;
(c) about 8% melamine (2,4,6-triamino-1,3,5-trizine);
(d) about 20% water;
(e) about 23% aluminum trihydrate; and
(f) about 5% melamine-formaldehyde resin.
6. The flame retardant carpet of claim 1 , wherein the intumescent material comprises:
(a) about 20% acrylic binder;
(b) about 20% water;
(c) about 24% ammonium polyphosphate;
(d) about 8% melamine cyanurate; and
(e) about 28% alumina trihydrate.
