Publication number: 20140373967Abstract: The present invention provides fabrics with cut loop group and a manufacturing method thereof, wherein the core yarn at the section where said loops are being cut is outwardly protruded from the covering yarns, while the synthetic fiber divided yarn, which is a core yarn, is separated into multiple filaments. The fabrics with cut loop group show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch owing to a split-type microfiber and a viscos rayon yarn which comprises a covering yarn, and polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the synthetic fiber divided yarn which functions as a hook. Thus the fabrics with cut loop group according to the present invention can be used usefully in the products such as various kind of mats, towels, bathroom products, and the like including dishclothes and mops.Type: ApplicationFiled: May 3, 2013Publication date: December 25, 2014Inventors: Hyun Sam Lee, Sung Hoon Choi

In each cycle a top (1), (2), (3) and a bottom weft thread (4), (5), (6) are inserted between binding warp threads (9-12) and pattern warp threads (13-16) of a series of warp thread systems so that a fabric is woven. Top (1-3) and bottom weft threads (4-6) are inwoven by a respective set of binding warp threads (9, 10), (11, 12), thereby weaving two backing fabrics. Respective pattern warp threads (13), (14); (15), (16) are interlaced in a respective backing fabric and are rib-formingly passed around over a top (2), (3) or bottom weft thread (5), (6) running between the backing fabrics which is not inwoven by binding warp threads (9-12), so that two fabrics (17), (18) with a rib structure are woven one above the other.Type: GrantFiled: December 21, 1999Date of Patent: September 18, 2001Assignee: N.V.

Patent number: 6273148Abstract: With a method for face-to-face weaving pile fabrics, whereby weft threads (1-6) are brought between warp threads (7-12) of a series of warp thread systems so that two backing fabrics (21), (22) are woven located one above the other with tension warp threads (7), (10) and dead pile warp threads (13-20) inwoven in the backing fabrics, whereby pile warp threads (13, 14, 18, 20) in each backing fabric form respective pile loops around first (1), (4) and around second weft threads (2), (5) which respectively run along the back and along the pile side of a tension warp thread (7), (10), and whereby the pile-forming pile warp threads (13, 14, 18, 20) are cut through between the backing fabrics, the dead pile warp threads (13-20), running along the pile side of the second weft threads (2), (5), are inwoven.Type: GrantFiled: December 21, 1999Date of Patent: August 14, 2001Assignee: N.V.

Patent number: 6247505Abstract: This invention is aimed at providing a terry-cloth or velours fabric, and a predictably economic process for its production, whereby it is possible to optimally adapt the fabric to different purposes. The proposed approach is a process for producing a terry or velours fabric consisting of a carrier web and, anchored in the carrier web, a nap in the form of open or dosed loops, of a warp of cotton loops the cut or uncut loops of which extend from one surface of the carrier web, and of a warp of microfiber loops the cut or uncut loops of which protrude from the opposite surface of the carrier web, the said warp of cotton loops and, respectively, the warp of microfiber loops being interlaced on the respective surface from which they protrude at the time the carrier web is produced.Type: GrantFiled: June 23, 2000Date of Patent: June 19, 2001Assignee: Frottierweberei Vossen GmbHInventor: Horst Wörman

Patent number: 6186189Abstract: A method for manufacturing fabrics with a rib structure, in particular false bouclé fabrics is provided. On a weaving machine two series of warp threads (4, 5, 6, 10, 11); (7, 8, 9, 12, 13) are provided for weaving a respective fabric (21); (22). In successive insertion cycles, in each case, at least three weft threads (1), (2), (3) are inserted one above the other between the warp threads, so that in each case a set of weft threads (3), (2); (1), (2) running one above the other are inwoven by the warp threads (5), (6); (8), (9) of one of the other two series, and at least one weft thread (3); (1) is inwoven by the warp threads (8), (9); (5), (6) of the other series, so that two fabrics (20), (21) with a rib structure are woven simultaneously. A method for manufacturing loop pile fabrics is provided.Type: GrantFiled: June 22, 1999Date of Patent: February 13, 2001Assignee: N.V. Michel Van de WieleInventor: Nico Gheysen

Patent number: 6186186Abstract: A face-to-face weaving machine with a weft insertion device (1), (2) is provided in order according to a top and a bottom insertion path to insert weft threads between warp threads (3-12). A lifting device (18, 19) works together with shed-forming devices (14), (15), (16), (17), of which first shed-forming device (14) is provided in order to bring warp threads (5), (6) above and between the insertion paths; second shed-forming device (15) is provided in order to bring warp threads (3), (4) between and below the insertion paths; third shed-forming device (16), (17) is provided in order to bring warp threads (7-12) above, between and below the insertion paths, such that the ratio (H/h) between, on the one hand the intermediate distance (H1), (H2) between two warp thread positions and on the other hand the lifting height (h) applied by the lifting device, is greater, preferably 1.5 times greater, for the third shed-forming device (16), (17) than for the first (14) and the second shed-forming device (15).Type: GrantFiled: May 26, 1999Date of Patent: February 13, 2001Assignee: N.V.

Patent number: 6173746Abstract: A method for weaving fabrics with a two-sided rib structure, such as false boucl{acute over (e)} fabrics, comprises forming a fabric on a weaving machine from weft threads and warp threads of a series of warp thread systems, with sets of at least two weft threads running one above the other. Each warp thread system comprises at least three pattern warp threads of which two opposite each other, respectively along the upper side and the lower side of the fabric, form a number of ribs. The pattern warp threads are alternately rib-formingly passed around over one or several sets of weft threads and are interlaced in the fabric, while each additional pattern warp thread is inwoven in the fabric between weft threads of the sets over which other pattern warp threads are rib-formingly passed around.Type: GrantFiled: July 7, 1999Date of Patent: January 16, 2001Assignee: N.V.

Patent number: 5154208Abstract: Lancet holder for face-to-face weaving loom, comprising a slat-shaped section (1) onto which lancets (2) can be pushed. A comb (4) with teeth (8) lies directly in front of section (1). Each lancet (2)--extending in the warp direction--can be situated between two teeth (8), and the width of the space between two teeth (8) is slightly greater than the thickness of a lancet (2), so that they remain with their flanks at right angles to the section (1). Section (1) and part of the lancets (2) pushed onto it may be enclosed by a surrounding wall (9), (10) which is rounded off and smooth along the outside, and the comb (4) is set up along the front open side of said surrounding wall, so that the lancets (2) can extend from the enclosed space between the teeth (8).Type: GrantFiled: May 21, 1991Date of Patent: October 13, 1992Assignee: N.V.
