  • Patent number: 10258114
    Abstract: Stringers without fastener tape have continuous fastener elements and have element fixing members wherein the fastener elements are sewn together by a sewing thread. The element fixing members are inserted between upper and lower leg sections of the fastener elements. The sewing thread comes in contact with and straddles the upper and lower leg sections of each fastener element and pierces the element fixing members between the fastener elements. As a result of such stringers without fastener tape, the fastener elements can be held and the weight and cost of an article with a slide fastener can be reduced.

  • Publication number: 20190021454
    Abstract: The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.
