Abstract: A tufting process is provided whereby one pile length is cut from a pile material which is to be joined to a backing material by means of a cutting edge after the formation of each loop. Provision is also made for the cutting process to be effected by means of the vibrational cutting movement of a cutting edge, in particular with the aim of improving the cut and reducing wear. In order to implement such a process, a tufting device is provided which incorporates a row of side by side loopers. The loopers move to-and-fro for the purpose of looping the pile material. Each looper includes a base installed in a looper block. A shaft extends from the block and has a nose for collecting the yarn on its front end. The shaft further incorporates a cutting edge configured so as to perform the cutting process. Each looper is adapted to be coupled with a vibrating drive which superimposes a vibrational motion on top of the to-and-fro motion.
Abstract: A synthetic yarn made from a blend of base fibers selected from the group consisting of polyester, nylon 6 and nylon 66, and 1-12 weight percent of a heat activated binder fiber having a melting point within the range of 165.degree.-190.degree. C., said binder fiber being made from a copolyamide which is derived from a mixture of 50 to 85 wt. % caprolactam, 0 to 40 wt. % hexamethylenediamine adipate or a combination of hexamethylenediamine and adipic acid, and optionally a salt selected from the group consisting of hexamethylenediamine dodecanedioate, hexamethylenediamine azeleate, hexamethylenediamine sebacate and hexamethylenediamine terephthalate; and a chain terminator selected from at least one of the group consisting of a fatty acid and a fatty amines, wherein said fatty acid or fatty amine include at least 14 carbon atoms.
Abstract: Method to refurbish cut or loop pile carpet products including carpet tiles by passing the product under a high pressure water or liquid dispensing head projecting a stream of water against the subject product at a pressure in the range of 200-2000 p.s.i.g.
Abstract: Shearing operations on textile pile fabrics may be repeatably controlled precisely by controlling operating parameters of the shearing machine to maintain constant the average number of times each pile loop of the fabric is cut by the shearing blades of the shearing cylinder, which is accomplished by calculating a numeric value representing cuts per pile loop as a function of the rotational speed of the cylinder, its number of shearing blades, the widthwise dimension of the nose surface of the fabric rest, and the fabric traveling speed, and selectively adjusting one or more of these parameters as necessary to achieve the desired number of cuts per fabric loop.
Abstract: A heavy, roller-mounted base plate has thereon a conventional pile carpet trimmer having a shearing head disposed to be swung into and out of a pile access opening in the base plate either to trim the pile of a carpet by sliding the plate on top of the pile, or to bevel the carpet edge by sliding the plate beneath and along one edge of the carpet. Attached to the plate adjacent opposite ends of its pile access opening are two, linearly aligned guide members, which slidably engage a carpet edge during a beveling operation. A retention bracket projects from one of the guide members to overlie the pile surface to prevent any bunching or folding of the carpet edge during the edge-beveling operation.
Abstract: A textile material which consists of interweaving of synthetic filaments as warps and wefts having a fluffy layer of a pile of rayon fixed to the textile material by having its base curved around warps and wefts and wherein the pile is shaved to constitute a uniform surface wherein the material is useful for general cleaning when used with or without a cleaning product.
Abstract: A process and apparatus for cutting tufted loops of yarn of a fabric, such as a carpet, by applying sufficient energy from an ultrasonically vibrating horn, operating with either a shearing or a pincer action in cooperation with a mechanical device, either or both having a cutting edge, to cause at least some of the filaments in said yarns to soften and fuse to adjacent filaments during cutting of said tufted loops.
Abstract: A self-engaging separable fastener is disclosed which comprises a base member of woven separable fastener material having at least two adjacent mating fastener sections. At least one section is defined by a plurality of loops upstanding from the base member, and the other section is defined by a plurality of hooks upstanding from the base member. The loops are formed of respective generally parallel rows of multifilament yarns interwoven into their respective base section so as to repeat the same loop direction and construction every predetermined number of picks and the hooks are cut from respective generally parallel rows of loops of monofilament yarns interwoven into their respective base section so as to repeat their loop direction and construction every predetermined number of picks, which latter number of picks is greater than the number of picks in which the direction of the multifilament loops is repeated.
Abstract: A high density textile fabric having an excellent water-repellent property comprises a woven fabric having at least one water-repellent surface layer formed by a number of warps and wefts each consisting of a number of extremely fine, water-repellent fibers having a denier of 1.2 or less, the surface layer having a sum of cover factors (CF) in the warp and weft directions thereof, of from 1,400 to 3,400 determined in accordance with the equation: ##EQU1## wherein n represents the number of the warps or wefts per inch of the fabric and de represents a denier of the warps or wefts.
Abstract: A cut pile fabric such as a velvet composed of a synthetic fiber pile having deep color shade and smooth touch on its pile surface, the piles thereof having non-mushroom shaped cut ends at their tip portions, defined by the equation d.sub.1 /d.sub.2 .ltoreq.1.3, where d.sub.1 is the maximum diameter of the tip portion and d.sub.2 is a diameter of the remaining portion of the piles. The pile fabric is obtained by utilizing, as a pile yarn, a synthetic yarn having a breakage strength of less than 2.8 g/De, a primary yielding strength of more than 1.2 g/De, a breakage elongation of less than 50%, and a primary yielding elongation of less than 10%. Such synthetic yarn can advantageously be prepared by a crystallization drawing process.
