  • Knitted band for zipper
    Patent number: 7739887
    Abstract: A woven band for a zipper is provided. The woven band is made by a double needle bar raschel knitting machine and has a predetermined length in a warp direction. The woven band includes a convex portion formed on one side thereof for joining to a zipper and a band portion connected to the convex portion. As the convex portion has large thickness and high strength, the joint strength of the convex portion and the zipper is increased.

  • Bilaterally bendable warp-knit tape
    Patent number: 7610777
    Abstract: A bilaterally bendable warp-knit tape includes a plurality of first, second, and third braided wires. The first and second braided wires are staggered while extending circularly along a warp direction of the tape with a proper distance from left to right to form a predetermined number of wales on the tape. A span distance of lapping from left to right of the second braided wires is smaller than that of the first braided wires. More than one third braided wire is disposed in middle of the tape, and is continuously lapped while extending upward on the corresponding wale in a form of a crochet along the warp direction of the tape to form a fixing region having a predetermined width and extending along the warp direction. The fixing region is for disposing male and female buckles. The warp-knit tape has desired flexibility and extensibility on both sides for bilateral bending.
