Abstract: A double knit fabric is described which has a front surface comprising courses of plain knit stitches formed from two synthetic fiber yarns such as polyester and rear surface comprising courses of plain knit stitches formed from a natural fiber yarn such as cotton, or a blended yarn. Each of the front and rear surface courses are interlocked with one another by the engagement of a rear surface loop with a front surface loop every several wales to form spaces between the front and rear surfaces and to form spaces in the rear surface through which portions of the front surface appear.

Abstract: A double knit fabric having at least a first set of alternating wales comprising a first wale and a second wale, said first set of alternating wales forming the face side of the fabric;at least a second set of alternating wales comprising a first wale and a second wale, said second set of alternating wales forming the reverse side of the fabric; andat least six feed yarns, wherein the first wale of said first set of alternating wales has knit stitches produced by the first, third and fifth feed yarns, wherein the second wale of said first set of alternating wales has knit stitches produced by the second, fourth, and sixth feed yarns, wherein the first wale of the second set of alternating wales has knit stitches produced by the fourth feed yarn, and wherein the second wale of the second set of alternating wales has knit stitches produced by the first feed yarn.

Abstract: A fabric is produced in a stitch-through type machine such as a Malimo machine using the apparatus and method of the invention which has at least two warp yarn design elements laid on a flexible substrate (e.g., a layer of textile filling elements) along rectilinear or non-rectilinear paths and on which a plurality of adjacent design elements are twisted (e.g., symmetrically at 180.degree. per twist) in an aesthetically pleasing configuration at spaced intervals along the warp direction. The design elements are bound to the substrate by knitting thread which forms a multiplicity of warpwise loop chains (e.g., a half-tricot stitch) to secure the substate and design elements against relative displacement and to form thereby an integrated fabric structure.

Abstract: A double knit fabric of a given gauge (usually fine gauge) is provided with an inlay of a coarser gauge yarn on a knitting machine with two needle beds. One side of the fabric is formed of only relativey fine gauge yarn and the relatively coarser inlay yarn is confined to the other or surface side of the fabric. Selected needles in one of the needle beds are replaced by drive elements. The inlay yarn is laid in by an inlay wheel driven in synchronization with the needle bed by said drive elements.

Abstract: A double knit fabric is knitted from at least a first yarn and a second yarn, said first yarn having a boiling water shrinkage ranging from boiling water shrinkage ranging from about 50 to about 95 percent, and said fabric containing from about 70 to about 90 percent of the first yarn and about 10 to about 30 percent of the second yarn.

Abstract: An elastic fabric containing producers twist continuous filament yarns, which in spite of their features make it possible to obtain a fabric having high elasticity and power stretch indexes; said synthetic yarns are knit just as issued from spinning, without previously being submitted to any texturing or warping operation, in a large diameter interlock type circular machine, with two sets of needles, on a pique basis and with interlacing interlock and jersey courses. In the interlock courses a first synthetic yarn is incorporated, while in the jersey courses a polyurethane originated elastomeric yarn tensioned under control, having as a companion or carrier yarn a second synthetic yarn, is incorporated.

Abstract: A double-velour vascular graft has a tubular body or trellis with loops projecting both outwardly and inwardly from said trellis. The loops on both the inner and outer surfaces of the trellis provide for more effective preclotting and ingrowth of tissue without impeding the flow of blood through the tubular body. The graft is produced on a double-needle bar warp-knitting machine using two outside beams and two inside beams, the beams feeding yarn for the loops to said knitting machine at a greater rate than the beams feeding yarn for the trellis.

Abstract: A method of knitting an integral pocket in a knitted garment which includes the steps of knitting the front and rear garment panels of single layer construction, knitting one or more integral pockets by knitting an enclosed tubular area which is completely closed on all sides, said tubular area including a portion of a knit panel, the said tubular pocket being knit to a pattern either conforming with or contrasting from the remainder of the knit panel. The top last course of the knit-in tubular pocket is easily opened by creating a long knitted loop on each end of the top corners of the pocket to permit pulling a thread or yarn from either corner to automatically open the tubular pocket.

Abstract: The present invention provides a method of producing double-knit goods or fabrics having additional fleece threads incorporated into one face or both faces thereof and a nap or fleece is imparted from these threads by napping. The method comprises feeding the backing or ground yarn only to the needles of both needle sets (dial and cylinder) which are fully raised for stitch formation, while feeding the additional fleece thread to the needles of one needle-set (cylinder) which form stitches and tuck loops, and/or feeding the backing yarn and the additional fleece thread in successive steps of operation and knitting them into common stitches on one needle set (dial) and into stitches and tuck loops on the other needle set (cylinder).

Abstract: A slide fastener tape of a warp-knitted structure is provided with a web portion and a marginal edge portion extending lengthwise thereof, both portions being interconnected by a relatively strong transversely extending lapping threads. A combination of chain stitches and tricot stitches having alternate closed and open laps is utilized in the formation of the web portion to provide a stable knit structure, while the marginal edge portion is reinforced by double-layer tricot stitches to render this portion uniformly swollen so that the fastener elements can be securely mounted with their legs astride of the swollen edge.

Abstract: A knitted structure and method of making same which includes simultaneously knitting two concentric tubes and interconnecting the tubes by knitting to produce seams which define a garment of juxtaposed portions of the two tubes. Each concentric tube includes a plurality of feeds per course knitted separately on the dial and cylinder needles, respectively, of a circular knitting machine.

Abstract: An elastic double-knit fabric having alternating front and back wales knit from an elastic and inelastic yarn knit together in spaced patterns of adjacent stitches in adjacent front wales and in selected stitches in at least every fourth course in the back wales, all the remaining stitches in the fabric containing only inelastic yarn.

Abstract: A fleece fabric is produced by first consolidating a fleece into a primary fabric by fleece knitting, and then stitch bonding the primary fabric with warp yarn.The fabric is at least as strong and stable as ordinary stitch bonded fabrics, but has substantially improved pilling and abrasion resistance, and a much wider range of patterning and surface texture possibilities.
