  • Patent number: 10986878
    Abstract: A composite waterproof breathable sock with two-way extensible properties, wherein each sock is formed by lamination of an outer layer, an inner layer and an intermediate waterproof and breathable sock-like film component on a one-step forming mould. The outer layer, or both the outer and inner layers, is/are knitted by deploying fine twisted elastic yarns consistently into all the knitting courses of the main body for each such layer, so as to make the composite sock therefore extensible in both weft X and warp Y directions after lamination of the layer(s) to the waterproof film component such that the composite sock will be recoverable uniformly after stretching to a relaxed conformation. The composite sock can be sewn with a water seal kit inside the cuff band, wherein the cuff band is extended from the outer component of the sock. The in-cuff seal kit can be constructed by a sew-in waterproof polyurethane elastic fabric in round shape.

  • Patent number: 10184196
    Abstract: There is provided a method for knitting a knitted fabric capable of forming a decoration unit of a novel shape using a flat knitting machine. A decoration unit (2) is formed on a surface of a base knitted fabric portion (1), the decoration unit (2) being configured by a lower edge (2D) extending in a knitting width direction of the base knitted fabric portion (1), a left edge (2L) extending in a direction intersecting the knitting width direction from a left end of the lower edge (2D), and a right edge (2R) extending in a direction intersecting the knitting width direction from a right end of the lower edge (2D). The lower edge (2D) is configured by a cross-over yarn extending in the knitting width direction of the base knitted fabric portion (1). The left edge (2L) and the right edge (2R) are configured by stitches stretched in a direction intersecting the knitting width direction. The cross-over yarn and the stitches are knitted all at once.

  • Patent number: 10149500
    Abstract: The present invention relates generally to an arch supporting sock in which proper curvature of the arch is reinforced and strain on the leg, arch, and greater foot area is decreased, comprising a first region having a first elasticity coefficient and a second region, roughly encompassing the arch of the foot, having a second elasticity coefficient, wherein the second region provides greater structural support than the first region and the second elasticity coefficient is lower than the first elasticity coefficient. The arch supporting sock may further comprise one or more perimetric boundaries between the first and the second region, each boundary comprising a perimetric elasticity coefficient, wherein one or more perimetric boundaries has a perimetric elasticity coefficient less than the first and second elasticity coefficients. Embodiments of the sock include non-interchangeable left or right socks with the arch support assemblage residing on the inner half of the sock.

  • Patent number: 6415632
    Abstract: A method for producing a knitted fabric with a circular knitting machine with cylinder and dial, particularly for producing footlets, comprising the steps of producing a knitted fabric with a particular process that achieves high elastic deformability for the fabric. By virtue of this high elastic deformability, the fabric is particularly adapted to be used to produce footlets, obtainable simply by cutting, from the fabric according to the invention, a contoured part, to which a pretensioned elastic band is applied at its perimeter. The resulting footlet has an elastic deformability that achieves optimum fit yet can have, on the side adapted to be directed toward the user's foot, an inextensible natural thread.

  • Patent number: 6341505
    Abstract: An improved sock wherein moisture distribution, wicking, evaporation and other phases of control are all managed by the sock construction. The moisture management sock has a toe portion knit of predominantly of hydrophilic yarn; a heel portion knit of predominantly of hydrophilic yarn; and alternating rings of hydrophobic and hydrophilic yarn located between said toe portion and said heel portion. Moisture absorbed from the wearer's foot by the hydrophilic yarn is transferred by wicking action into the hydrophobic rings and then to the leg portion to be evaporated therefrom.

  • Patent number: 6324874
    Abstract: The present invention provides a pile sock which can lighten a sense of tiredness and has improved air permeability. A sole portion of the pile sock is knitted almost thoroughly in pile stitches. The sock is excellent in the cushioning properties and able to reduce load to a foot. It also has good sweat-absorption characteristics. A toe-side section of the pile sock works effectively to prevent slippage. An arch region of the sole portion has a smaller area of the pile stitch segments than an area of the plain stitch segments in comparison with a ground contact region of the sole portion. Arranging the plain stitch segments and the pile stitch segments in a lattice pattern allows a sense of stimulation and air permeability to be uniformly provided.

  • Patent number: 6257025
    Abstract: A method for knitting hosiery or similar tubular knit structures, and hosiery knitted according to the method, are disclosed. A plurality of first courses are knitted on a circular knitting machine using a first group of needles being a fraction of the total number of needles on the machine. Selected needles of the first group are taken out of action, but the final course knitted is retained on the needles out of action. The needles still in action are used to knit a plurality of second courses. After the second courses are complete, the needles out of action are brought back into action, and a third plurality of courses is knitted using all the needles of the first group. The second plurality of courses folds over upon itself to form a double layer of adjacent courses surrounding an opening. Further courses are knitted using more needles, the number of needles in action determining the size of the hose.

  • Patent number: 6047571
    Abstract: A convertible stocking for use by dancers is disclosed. The stocking may be converted from a footed to footless stocking without changing the stocking. The stocking has a main tubular portion, a toe pocket portion, and a foot opening collar. The main tubular portion is knitted in a continuous, circular manner to form a substantially uniform knit tube having a border at one end. The toe pocket portion is knitted in a continuous, reciprocating manner onto about one half of the border of the main tubular portion using successive courses of yarn beginning with about one half the total number of knitting needles of the knitting machine and progressively decreasing the number of knitting needles used to knit each course and then increasing the number of knitting needles to about one half the total number of knitting needles thereby forming a knitted pocket over about one half the border of the main tubular portion. The pocket has a terminating edge.
