Abstract
Provided are carpets and textile layers comprising a plurality of fibers and layer for locking the plurality of fibers, and methods for making them.
Claims25
A carpet comprising:
- (a) a plurality of fibers;
- and
- (b) an adhesion layer for locking the plurality of fibers, wherein the adhesion layer comprises a polymer blend containing:
- (i) a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- and
- (ii) a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- wherein the second propylene-based polymer is different than the first propylene-based polymer;
- wherein the polymer blend has a melt viscosity, measured at 190° C. according to ASTM D-3236, of about 500 to about 25,000 cP.

A carpet comprising:
- (a) a primary backing layer having a face side and a back side;
- (b) a plurality of fibers attached to the primary backing layer and extending from both the face side and the back side of the primary backing layer;
- and
- (c) a second layer attached to the back side of the primary backing layer,
- wherein at least one of the primary backing layer and the second layer comprises a polymer blend comprising:
- (i) a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- and
- (ii) a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- wherein the second propylene-based polymer is different than the first propylene-based polymer;
- wherein the polymer blend has a melt viscosity, measured at 190° C. according to ASTM D-3236, of about 500 to about 25,000 cP.

- and
- (ii) a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- wherein the second propylene-based polymer is different than the first propylene-based polymer;
- wherein the polymer blend has a melt viscosity, measured at 190° C. according to ASTM D-3236, of about 500 to about 25,000 cP.
5 more elements
A method for making a carpet or a textile layer, comprising the steps of:
- (a) providing a plurality of fibers;
- (b) applying a melt comprising a polymer blend to the plurality of fibers to form an adhesion layer for locking the plurality of fibers,
- wherein the polymer blend comprises:
- (i) a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- and
- (ii) a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
- wherein the second propylene-based polymer is different than the first propylene-based polymer,
- wherein the polymer blend has a melt viscosity, measured at 190° C. according to ASTM D-3236, of about 500 to about 25,000 cP;
- and
- (c) forming a carpet or a textile layer.
