Abstract
A pile fabric suitable for use as a primary carpet fabric within a carpet construction or composite such as a cushioned carpet or tile. The primary carpet fabric includes a plurality of pile-forming yarns tufted through or adhered to a primary backing of integral dimensionally stable character. A cushioning layer of foam, felt, fabric, or other suitable cushioning material may be disposed at a position below the primary carpet fabric.
Claims29
A carpet construction or composite including a surface forming pile fabric, wherein the pile fabric comprises:
- a pile surface formed from a plurality of yarn elements;
- and
- a primary backing disposed in underlying relation to the pile surface, wherein at least a portion of the yarn elements are tufted through the primary backing and wherein the primary backing comprises a multi-layer composite structure of sandwich construction comprising a pair of opposing layers of nonwoven construction and at least one additional layer disposed intermediate the opposing layers wherein at least one of the opposing layers is a spun bonded nonwoven construction and wherein said at least one additional layer comprises woven stabilized polypropylene containing a nucleating agent.
A carpet construction or composite including a surface forming pile fabric, wherein the pile fabric comprises:
- a pile surface formed from a plurality of yarn elements;
- and
- a primary backing disposed in underlying relation to the pile surface, wherein at least a portion of the yarn elements are tufted through the primary backing and wherein the primary backing comprises a multi-layer composite structure of sandwich construction comprising a pair of opposing layers of nonwoven construction and at least one additional layer disposed intermediate the opposing layers wherein at least one of the opposing layers is a spun bonded nonwoven construction and wherein said at least one additional layer comprises nonwoven stabilized polypropylene containing a nucleating agent.
A carpet construction or composite including a surface forming pile fabric, wherein the pile fabric comprises:
- a pile surface formed from a plurality of yarn elements;
- and
- a primary backing disposed in underlying relation to the pile surface, wherein at least a portion of the yarn elements are tufted through the primary backing and wherein the primary backing comprises a multi-layer composite structure of sandwich construction comprising a pair of opposing layers of nonwoven construction and at least one additional layer of glass disposed intermediate the opposing layers and wherein at least one of the opposing layers is a spun bonded nonwoven construction of intermingled fiber elements of stabilized polypropylene containing a nucleating agent and including a plurality of fusion bonding points between the intermingled fiber elements.
