A carpet recycling method is disclosed. In a toroidal flow pulper, pieces of carpet are disintegrated in a quantity of liquid to form a slurry of fibrous carpet materials and carpet ash. At least a portion of the fibrous carpet materials are separated from the slurry, and the separated fibrous carpet materials are dried. At least a portion of the carpet ash is isolated from the slurry, and the isolated carpet ash is dried. Thus, a first output comprising dried separated fibrous carpet materials is produced, and a second output comprising dried carpet ash is produced.

Carpet recycling process and method

Disclosed herein are carpets and carpet tiles comprising a primary backing material having a face and a back side; a plurality of fibers attached to the primary backing material and extending from the face of the primary backing material and exposed at the back side of the primary backing material; and an adhesive composition. The adhesive composition generally comprises at least one homogenously branched ethylene polymer. Also disclosed are methods for manufacturing the disclosed carpets and carpet tiles.

Homogeneously branched ethylene polymer carpet backsizing compositions

Blanket with fingers

The present invention pertains to carpet and method of making it. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched linear ethylene polymer. The method includes extrusion coating at least one homogeneously branched linear ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include preheating the primary backing prior the extrusion step, multilayer adhesive backings, washing or scouring the primary backing prior the extrusion step, and utilizing adhesive polymeric additives, high heat content fillers, blowing agents and/or implosion agents. The constructions and methods described herein are particularly suited for making carpet tile.

Carpet, carpet backings and methods

The present invention pertains to carpet and methods of making carpet. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched ethylene polymer. The method includes extrusion coating at least one homogeneously branched ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred homogeneously branched ethylene polymer is a substantially linear ethylene polymer. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.

Homogenously branched ethylene polymer carpet backsizing compositions

Compositions having improved ignition resistance

This invention relates to a non-contact coating method for producing a continuous coating and articles constructed therefrom. This invention further relates to a method for producing a textile material with a moisture-impermeable barrier layer and to a method for producing a moisture-absorbing article of hygiene which has such a barrier layer. This invention particularly relates to a textile material and hygienic disposable articles comprising a body fluid impermeable barrier layer which can be produced from a non-contact coating method. Preferably, the thermoplastic composition used for producing the barrier layer exhibits certain rheological characteristics and comprises at least one homogeneous linear or substantially linear interpolymer of ethylene with at least one C.sub.3 -C.sub.20 alpha-olefin, further characterized by each said interpolymer having a polydispersity less than about 2.5.

Disposable articles having a continuous thermoplastic coating comprising

This invention relates to compositions comprising ethylene interplymers, such as a linear or substantially linear ethylene interpolymer and polydimethylsiloxane. The compositions have good abrasion resistance without sacrificing coefficient of friction.

Polydimethylsiloxane containing polymer blends

An ethylene polymer extrusion composition having high draw down and substantially reduced neck-in, a process for making such a composition and a process of using such a composition to prepare extrusion coatings, extrusion profiles and extrusion cast films are disclosed. The ethylene polymer extrusion composition is made of 75-95 weight percent of at least one ethylene .alpha.-olefin interpolymer and 5-25 weight percent of at least one high pressure ethylene polymer characterized as having high melt strength and a broad, bimodal molecular weight distribution. In profiles, coatings or films, the composition can be used as sealant, adhesive or abuse resistance layers.

Extrusion compositions having high drawdown and substantially reduced

A process and thermoplastic composition for high line speed extrusion without high neck-in and draw resonance are disclosed. The thermoplastic composition is made of at least one ethylene polymer having a Dow Rheology Index (DRI) of at least 0.1 or, alternately, at least one substantially linear ethylene polymer, used alone or in combination with at least one high-pressure ethylene polymer and/or with at least one heterogeneous linear olefin polymer.
