Abstract:
The invention is directed to a synthetic turf yarn, to a method of preparing said synthetic turf yarn, to artificial turf comprising said synthetic turf yarn, and to a method of preparing artificial turf. The synthetic turf yarn of the invention comprises an aliphatic polyester and a copolyester of butanediol, terephthalic acid and a linear aliphatic dicarboxylic acid selected from the group consisting of succinic acid, adipic acid, and sebacic acid.
Abstract:
A carpet constructed from a biodegradable nonwoven face layer and a backing layer that is biodegradable and/or recyclable. The face layer comprises a needle-punched nonwoven web formed from a blend of different fiber types each of which is biodegradable, the blend comprising face fibers having a relatively high decomposition temperature and thermally activatable binder fibers having a thermal activation temperature lower than the decomposition temperature of the face fibers. The binder fibers bind to one another and to the face fibers. The face fibers can comprise one or more types of fibers that are biodegradable. Suitable fiber types include but are not limited to wool, hemp, cotton, polylactic acid, jute, flax, kanaf, sisal, rayon, and silk. The binder fibers in some embodiments of the invention comprise low-melt polylactic acid.
Abstract:
A carpet in tile or roll form is produced using an open mesh reinforced foam layer with foam nodules. The carpet is produced having a primary backing through which carpet fiber bundles are tufted and a precoat layer which locks the tufts in place to prevent easy extraction of the fibers so that a tufted face and a relatively smooth back face are provided. The foam layer with foam nodules is brought into intimate contact with the relatively smooth back face, and is substantially permanently adhered to it producing a carpet tile or roll that is substantially prevented from curling or doming (or they are significantly reduced) and may be installed without adhesive if desired. Adhering may be practiced by using a non-fused adhesive formulation which is subsequently fused at a low temperature (about 310° F. or less), or by forcing the foam layer with foam nodules into contact with the carpet back while the hot melt backing is still in a fluid form, or by use of a thermoplastic layer between the carpet and foam sheet.
Abstract:
Carpet coating compositions are disclosed which comprise 40 to 80 percent by weight filler and 20 to 60 percent by weight of a latex binder, the binder comprising an emulsion polymer ofa) 40 to 80% by weight of a vinyl ester of an alkomoic acid, the acid having from 1 to 13 carbon atoms;b) 5 to 25% by weight of a copolymerizable comonomer having a Tg of at least 50.degree. C.; and;c) 10 to 30% ethylene.
Abstract:
A LAMINATE STRUCTURE, AS IN A CARPET, IN ONE FORM COMPRISES A NON-WOVEN HEAT SEALABLE FABRIC, HEAT SEALED ON ONE SIDE, LAMINATED WITH AN ADHESIVE TO A FACING LAYER OF HEAT SEALABLE FIBERS, APPLIED AS BY AN EMBOSSING ROLL WHICH CAN BE HEATED. THE NON-WOVEN FABRIC CAN BE A NEEDLE-PUNCHED ASSEMBLAGE OF A SCRIM AND FIBERS AND THE ASSEMBLAGE HEAT SEALED ON THAT SIDE OF THE SCRIM FROM WHICH THE NEEDLES HAVE EMERGED THUS TO LOCK THE FIBERS INTO THE SCRIM WHEN HEAT SEALING TO PROVIDE A FIBROUS, NON-HEAT SEALED PAD SIDE OF THE ASSEMBLAGE. THE ADHESIVE CAN BE A THERMALLY RESPONSIVE, I.E., A THERMOPLASTIC OR THERMOSETTING, FILM, POWDER OR MELT. THE ADHESIVE IN TACKY, FIBER RECEIVING CONDITION, AS AFTER BEING PASSED THROUGH A HEATING ZONE, IS PASSED TOGETHER WITH A FACE YARN WEB THROUGH AN EMBOSSING ZONE, THE EMBOSSING MEMBER OF WHICH CAN BE HEATED. IN A MODIFICATION A FURTHER BACKING CAN BE
APPLIED TO THE NON-HEAT SEALED PAD SIDE. WHEN THE NONWOVEN FABRIC CAN BE READILY HEAT SEALED IT CAN BE PASSED DIRECTLY TOGETHER EITH THE FACE YARN TO A HEATED EMBOSSING ROLL OR PRESS AND THE TWO HEAT SEALED THERE TOGETHER WITHOUT USE OF ADHESIVE. LIKEWISE, THE SECOND BACKING CAN BE SO APPLIED.
Abstract:
The adhesion of carboxylated SBR adhesive to polypropylene carpet backings is improved by a coating on the polypropylene of chlorinated polypropylene having a chlorine content of 10-20%.
Abstract:
A paintable cloth includes a woven fabric including plant fibers, especially flax, jute, ramie and/or sisal fibers, the woven fabric additionally being coated with a finish.
Abstract:
A method for providing a textile product includes the steps of providing yarns, contacting the yarns with a support material to form an intermediate product and bonding the yarns to the support material to form the textile product, wherein the bonding takes place by providing a reactive nucleus precursor at a site where the yarns contact the support material, and converting the precursor into a compound having multiple reactive nuclei in the presence of a compound having multiple nucleophilic groups, as well as a textile product obtainable by the method, uses of that product and lignin for use in producing such a textile product.
Abstract:
A method and apparatus for making a pliable wallcovering. The wallcovering replicates the appearance of aged, cracked plaster wall finishes, can be readily hung over existing walls, and is durable. In the method of making the wallcovering a putty-like joint compound mixture is applied to a pliable stretchable woven sheet. The sheet is comprised of strands forming interstitial openings extending through the sheet. The joint compound mixture is forced through the interstitial openings and is allowed to dry. The dried joint compound mixture is cracked in a manner which renders the wallcovering pliable.
