Abstract: A method of precision cutting fabric material while obtaining cleanly cut edges involves placing the material on a flat support surface, identifying one or more regions of material to be cut, placing adhesive tape on both sides of the material, and then using an appropriate tool to first squeeze the tape into the fabric at the cutting region, and effecting the cutting of the taped material. A reinforcing woven fabric constituent for incorporation into a metal matrix composite, produced by the method, is also disclosed.

Abstract: The invention provides a method of providing a formable composite material comprising providing a reinforcing material (9) having a plurality of superimposed layers (1-6), each layer consisting of a plurality of unidirectional non-woven yarns or threads (10) laid side-by-side, the yarns or threads in at least some of the different layers extending in different directions, said layers being stitched (12) together, and before said stitching incorporating in or with the reinforcing material (9) a matrix material (7, 8).

Abstract: A method of knitting single knit fabrics on a circular knitting machine such that the fabric has improved elasticity, soft hand and drapeability and including controlling two types of needles arranged alternately in the cylinder and sinkers arranged in the sinker dial through four processes in which alternate needles are raised to the knitting level in the first process and intervening needles are raised to the tucking level and an old loop has cleared the latch on each needle and a previously fed yarn is held in the hook of each intervening needle, a first ground yarn is fed to the alternate and intervening needles and the needles are lowered to a high welt level for the alternate needles so that the old loop is not knocked over and a low welt level for the intervening needles so that the old loop is knocked over and a new double yarn stitch loop is formed. The levels to which the alternate and intervening needles are raised are reversed in the third process.

Abstract: A wiper for use in cleanrooms and other controlled environments is made using a knit fabric tube rather than a fabric sheet. The fabric tube is knit with a diameter approximately equal to the preferred wiper dimension and is presented directly to an apparatus for sealing and cutting. A sequence of spaced strips are fused into the fabric tube perpendicular to its length. Individual two ply wipers are separated from one another along a cut line midway in the strips. The wipers are characterized by lower costs due to fewer fabrication steps and a 50% reduction in the number of wiper edges requiring treatment.

Abstract: A knit pattern for fabrics which will not run when the fabric is torn or snagged. The knit pattern provides non-run pantyhose when use to knit pantyhose for women. The knit pattern consists of four repeating courses. The first course alternates a face loop stitch with a tuck stitch. The second course alternates a face loop stitch with a tuck stitch, with each face loop stitch of the first course being in the same column as each tuck stitch of the third course, and each tuck stitch of the first course being in the same column as each face loop stitch of the third course. The fourth course is knit into continuous face loop stitches.

Abstract: A warp knitted lace fabric comprising a plurality of chain stitches and a ground insertion yarn, pattern yarn and/or other yarn interconnecting said chain stitches, said plurality of chain stitches being made either as a whole or in part by a heat bonding yarn comprising a lace knitting yarn carrying a low-melting thermoplastic synthetic resin covering and said heat bonding yarn being thermally jointed to itself or to other component yarns at intersections.

Abstract: A knit construction having a repeating six-course, two wale pattern in which the six courses include four courses comprising alternating knit and tuck stitches and two courses comprising alternating knit and float stitches, and each of the wales includes the knit stitches of two of the courses of alternating knit and tuck stitches and one of the courses of knit and float stitches, the tuck stitches of the other two of the courses of knit and tuck stitches, and the float stitches of the other of the courses of knit and float stitches.

Abstract: A method is disclosed for knitting a two-way non-run ventilated fabric. The fabric is knit on a circular knitting machine having 11 thread feed positions but only 9 thread feeds operative at 3 different speeds.

Abstract: A knitted yarn and a method for knitting the yarn. The yarn comprises two strands formed into successive stitches alternately disposed about two needle axes. Alternate strands form the successive stitches along each axis. Each stitch on one axis is drawn through a preceding stitch on that axis. As a result, each stitch on each strand passes through an adjacent stitch formed of the other strand.Each stitch in a strand is formed at a single or one of two reciprocating latch needles which pull the newly formed stitches in each strand through preceding stitches in the other strand and cast off the preceding stitches. Then the needles extend to accept the next stitches formed in the strands. The yarn knitting apparatus feeds strands at a controlled rate to service bars which reciprocate and oscillate over the needles to form the stitches at the needles alternately each time the needles reciprocate.
