Abstract: A method for recycling a fiber laminae, the fiber laminae being impregnated with a partially cured resin, the partially cured resin being expired, the method comprising steps of jetting a solvent toward the fiber laminae; extracting the partially cured resin from the fiber laminae, said extraction being effected by impingements of the solvent jet against the fiber laminae's impregnated partially cured resin; and drying the fiber laminae.

Abstract: A camouflage system includes a camouflage surface having a plurality of segments. The camouflage surface includes a first pattern disposed on a first segment of the plurality of segments, the first pattern including a depiction of a first microterrain of a natural environment, a second pattern disposed on a second segment of the plurality of segments, the second pattern including a depiction of a second microterrain of the natural environment, and a third pattern disposed on a third segment of the plurality of segments, the third pattern including a depiction of a third microterrain of the natural environment. The first microterrain differs from the second microterrain and the second microterrain differs from the third microterrain.

Abstract: A method of making a variably reinforced elongate medical device includes braiding a reinforcing sleeve from a first strand including a first material and a second strand including a second material, exposing a portion of the braided reinforcing sleeve to a selected environmental stimulus or contacting the portion of the braided reinforcing sleeve with a selected substance, to thereby substantially modify the first strand in the respective exposed or contacted portion, and removing the substantially modified first strand from the respective exposed or contacted portion of the braided reinforcing sleeve, while the second strand is retained in the respective exposed or contacted portion.

Abstract: Process for treating threads by knitting-unraveling includes: knitting several individual threads (2) on a multi-feed knitting machine (1); carrying out one or more heat, chemical or other treatments, in one or more chambers (7); carrying out, in an unraveling unit (4), an unraveling with pulling on the first knit thread and winding or beaming the unraveled threads (2) individually or carrying out on these individual threads another treatment operation or a production operation, optionally with an intermediate accumulation of the threads. The invention can be applied more particularly in the field of the textile industry, in particular the treatment of threads, particularly texturing by knitting-unraveling.

Abstract: Methods for unraveling knitted fabrics and a machine for unraveling knitted fabrics in order to reuse the yarns of a knitted fabric to be unraveled; the methods providing that the yarns can be unraveled either by stretching and loosening the yarns or by twisting the yarn plies onto each other whatever the knit type and the number of yarns are and the methods having stretching-loosening and twisting characteristics.

Abstract: The machine comprises means for securing a piece of knitted fabric, pigtail guides for directing ends of yarn from the fabric to a former, a variable speed motor for rotating the former through a countershaft, a belt and a slip clutch. A traverse mechanism comprises a longitudinally movable shaft carrying pigtail guides for winding the yarn uniformly of the former. The formers comprise a number of wire stems projecting a number of wires stems projecting from a hub and having fittings with radial projections to prevent the yarn sloughing off. The countershaft is suspended by the belt.

Abstract: Apparatus for removing a fill yarn from a web of warp tows advances the web lengthwise across a tabletop having opposite pairs of bars at the leading edge thereof for separating the outermost tow at each of the opposite edges of the web from the remaining tows within the web. Rotatable cutting wheels which are resiliently urged against the top of a rotating shaft at the underside of the web sever the fill yarn between the outermost tows and the remaining tows of the web to form separate fill yarn lengths extending across the width of the web. As the advancing web is then divided along a central portion thereof, the separate lengths of fill yarn are removed by a hook mounted within a central portion of the tabletop and reciprocating between positions above and below the tabletop so as to hook each separate length of fill yarn and begin pulling it down through the tabletop.

Abstract: In a method of making carbon or graphite yarn, a bundle of single ply precursor yarns is knit into an elongated fabric to facilitate subsequent processing of the yarns. The elongated fabric is pretreated to facilitate carbonization thereof such as by being advanced in the direction of elongation thereof through a cleaning process. Thereafter the yarns remain in the form of the fabric to facilitate processing thereof through at least a carbonization step. The carbonization step may be accomplished by winding the elongated fabric onto skeins to a desired extent and then severing the fabric, following which the skeins are disposed in a carbonizing oven to at least partially carbonize the yarns. Thereafter, the fabric length on each skein may be deknitted, and the resulting bundle of single ply yarns is twisted to form a multi-ply yarn which is then fired to substantially raise the percentage of carbon in the yarns and then graphitized.

Abstract: A process for producing a non-woven fabric having excellent draping properties and strength and further having a handling similar to that of woven fabrics, which comprises drawing uniaxially or biaxially a non-woven sheet material comprising not less than 90% by weight of semi-drawn fibers of a linear high molecular weight compound (e.g. polyesters) having a breaking elongation of 80 to 150% wherein the fibers of said sheet material are crossed and intertwined with each other and are partially bonded at the crossing points, said drawing being carried out until the bonding of the fibers is partially broken or the fibers are partially cut.

Abstract: A weave-de-weave process in which a plurality of weft loops are fluidly injected from opposite sides and normal to a plurality of warp yarns to form a composite tape. The tape is deweaved after the warp is space dyed by splitting the interior of the tape to expose the looped ends of the weft.

Abstract: A deweaving apparatus for deweaving a fabric tape by separating and removing a weft filling yarn from a plurality of warp yarns. Control means are provided for sensing breakage of the warp yarns and weft yarn, as well as knots, splices and tangles in the tape, and in response to any such condition in the tape, stops the operation of the apparatus. Along with these means of automating the deweaving process, and greatly reducing operator attention required, a special divergence guide is fitted which accelerates loosening of the weft yarn over a very short path, thereby providing significant reduction in floor space required for the deweaving process.

Abstract: A method and apparatus for separating and winding pre-treated yarn, for example, tire cord, the method comprising two stages. In a first stage, a coated and heat-set fabric, constituted of longitudinally running warp cords and laterally running picks interlaced with the warp cords, is subdivided into a plurality of elongate tapes, each tape having a lesser number of warp cords than the fabric and picks of reduced linear extent. The tapes are then wound into respective packages. In the second stage, the tapes are unwound and divided each into a plurality of independent warp cords free from the picks. The warp cords are then wound into respective packages.
