摘要:
Described are methods of making a carpet by (a) providing a primary backing material having a front side and a back side, (b) tufting a yarn into the primary backing material to produce a carpet pile on the front side of the primary backing material and loops of the yarn on the back side of the primary backing material, (c) applying by slot coating a layer of a first melted coating composition onto the back side of the tufted primary backing material, (d) applying by slot coating a layer of a second melted coating composition onto the coating applied in step (c) thereby fixing the loops of the yarn to the primary backing material, and (e) applying and pressing a secondary backing onto the slot coated tackifying resin layers and pressing it to join the first and second tackifying resins and the primary backing and secondary backing and yarn loops together to form a carpet.
摘要:
The textile includes a plurality of raised ribs laterally spaced one from the other and straddling textile yarns between the raised ribs. A yarn strand of a color different than the color of the raised ribs and straddled fibers extends directly along one side of the raised ribs and a yarn strand of a different color extends along an opposite side of the raised ribs. Depending upon the perspective of the viewer of the textile surface, the color of one of the yarn strands is hidden from view, while the color of the other yarn strand is observable, rendering different optical effects (textile colors) to the viewer as a function of the viewer's perspective.
摘要:
By utilizing recovered polyvinyl butyral (30) in the production of carpet backcoatings (34), the amount of waste polyvinyl butyral that is landfilled or otherwise disposed of is significantly reduced, as is the need for manufacturing polyvinyl butyral. The recovered polyvinyl butyral (30) is size reduced (32) and then utilized by itself or with other ingredients (33, 36) to provide a composite used in the manufacture of a useful product (35, 37) (like carpet backing), and then the composite material is used to make the useful product (35, 37) (such as carpet backing (34), which is used as a primary or secondary backcoating (34) in the manufacture of new carpeting (35) or as a precoat, main back coat or combination precoat/main back coat (34) in the manufacture of new carpet tile (35) In addition, waste carpet (20) may optionally be used with the recovered polyvinyl butyral as a filler material (24); thus, further reducing the amount of waste that is landfilled or incinerated.

The covering includes (10), in order from exposed surface to underside, a tufted primary (12 and 14), a VAE precoat (16), a first layer of PVC (18), a fiberglass woven material (20), preferably a leno weave fiberglass material, embedded in the first layer of PVC (18) and a final layer of PVC (22) forming the underside of the covering. Dimensional stability is achieved with the woven or the leno weave fiberglass material (20) utilizing minimal quantities of PVC, while providing adequate curl and drape properties to the covering (10).
摘要:
A fabric (10) is provided having discrete surface portions (12, 14) of a primary backing (16) and tufted yarns (18) exposed on the technical face of the fabric. To form the fabric (10), the yarn feed controlled by servomotors is adjusted in increments to rob back yarn sufficient to pull out the previously tufted loops (20) in selected portions of the fabric (10), leaving the primary backing portion (12) of the pulled-out loops exposed on the technical face. By the selection process, random or patterned tufted portions (14) and exposed primary backing surface portions (12) are provided on the technical face of the fabric (10).
摘要:
The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven base layer and overlaid by a first PVC Layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.

摘要:
A covering for a floor, wall or ceiling surface includes tiles each having first and second discrete tile sections. The first section includes a primary backing exposed on one side of the tile forming a first discrete exposed surface portion and a plurality of yarns tufted into the primary backing with cut or loop yarns on the back side of the primary backing leaving backstitches forming a second discrete exposed surface portion of the first section. The primary backing and backstitches form the first and second surface portions, respectively, of the first section with aesthetic characteristics different from one another. The second section of the tile is formed of one of a woven fabric, a non-woven fabric and a tufted pile and which second section forms the remaining portion of the exposed surface of the tile.
摘要:
A fabric (10) is formed of yarns having soiling-hiding (18) and soilingprone (18) characteristics which are visually distinct one from the other in the surface of the fabric (10) once the fabric (10) has been soiled. The soiling-prone yarns (18) comprise yarns formed of multi-lobal fibers or filaments (22) where the soiling particles collect in the cavities of the lobed surfaces. Preferably, the soilinghiding yarns (18) are formed of hollowfil synthetic fibers or filaments (24). By embedding one or more yarns of the soiling-prone type (18) in the fabric (10), e.g., carpet, the yarns (18) become differentially visually distinctive relative to one another upon soiling of the fabric.
