Problems solved by technology

In such cases, the wet strength of the carpet is important as insufficient wet strength can cause the edges of the carpet to fray, fuzz during wet cleaning or possibly delaminate the secondary backing from the carpet causing warping of the carpet
Such surface changes in the carpet are undesirable and can reduce the useful life of the carpet

Embodiment 1

[0162]Samples A and B define a control carpet composite comprising a primary backing; attached to the primary backing material and extending from the surface of and exposed to the primary backing material a plurality of fibers on the back side of the ®; a layer of a commercially available precoat composition comprising an ethylene vinyl acetate emulsion and a filler other than a kaolin slurry; and a second backing material. Sample A defines a control carpet composite in which a commercially available precoat composition is deposited on the primary backing in an amount of 17 ounces per square yard. Sample B defines a control carpet composite in which a commercially available precoat composition is deposited on the primary backing in an amount of 15 ounces per square yard. Sample C is a carpet composite of the present invention wherein the precoat comprises a binder and a filler comprising a kaolin slurry as described in detail above, and wherein the precoat is deposited on the ...

Abstract

Disclosed is an improved carpet precoat composition, a carpet composition comprising the inventive precoat composition and methods of making the same. The improved precoat composition comprises a binder and a filler comprising a kaolin clay slurry. The carpet composition comprising the inventive precoat layer exhibits exceptional wet delamination strength.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to co-pending US Provisional Patent Application No. 62 / 267,754, filed December 15, 2015, which is hereby incorporated by reference in its entirety. field of invention [0003] The present invention relates to carpet precoat compositions, carpets comprising the precoat compositions of the present invention, and methods of making the same. More specifically, the present invention relates to carpet precoat compositions based on binders and fillers comprising kaolin slurries, carpets and carpet products having structures comprising the precoat compositions of the present invention, and methods of making the same. Background of the invention [0004] Most conventional carpets include a primary backing with yarn tufts in the form of cut or uncut loops extending upwardly from the backing to form a pile surface. In the case of tufted carpets, the yarns are inserted through the t...
