  • Patent number: 11280032
    Abstract: A knitted fabric having a heat generating function has a four-layer structure and can be knitted by a flat knitting machine. Knit stitching is used to knit first and second layers such that the second layer is fully covered under the first layer. Tuck stitching is used to knit the third layer such that one stitch is made to the third layer per a preset number of stitches made to each of first and second layers. Knit stitching is used to knit the fourth layer. After knitting, the fabric is soaked with water and spin-dried to form protrusions, spatially distributed as a centered rectangular lattice, on fabric surface. The second layer is electrically conductive for generating heat and is hidden inside the fabric. This layer is not easily hooked by a user during use and cleaning. The fabric is elastic and soft, and provides a comfortable feeling to the user.

    Abstract: A biocompatible surgical silk mesh prosthetic device employs a knit pattern that substantially prevents unraveling and preserves the stability of the mesh device, especially when the mesh device is cut. An example prosthetic device employs a knitted mesh including at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes. The at least two yarns include a first yarn and a second yarn extending between and forming loops about two nodes. The second yarn has a higher tension at the two nodes than the first yarn. the second yarn substantially prevents the first yarn from moving at the two nodes and substantially prevents the knitted mesh from unraveling at the nodes.

  • Patent number: 7539555
    Abstract: A knitting operation and a missing operation are alternately performed at the end portion of a knit fabric around a neck hole to reduce stitch density to less than that on the inside of the knit fabric, the stitch at the end part of the knit fabric is moved every three stitch courses to reduce a knitting width in increments of one stitch, and the stitch is formed at an empty needle resulting from the movement. Knitting conditions are also excellent since a neck hole or an armhole can be formed at a large slope such as two stitches in the horizontal direction every six stitch courses, and holing in the neck hole or an armhole can also be prevented, while, in addition, the wales are not laterally moved on the inside of the knit fabric.

  • Patent number: 7383705
    Abstract: When knitting a tubular knitted fabric having a difference in the number of wales between a front knitted fabric and a back knitted fabric, knitted fabrics are knitted alternately while turning the tubular knitted fabric and jointing the front section having a large number of wales at middle portions. In one example embodiment, turning is performed such that one boundary of boundaries coupling the fabrics is positioned between front and back needle beds. The numbers of wales of the fabrics caught on the needle beds on both sides are equalized and the fabric of the front section having a large number of wales is knitted from one boundary to the joints at a middle portion of the knitting width. Subsequently, the tubular fabric is turned such that the other boundary is positioned between the needle beds, and the fabric is knitted from the boundary of the front section to the joints and then coupled.
