Abstract
A double-sided engagement type fabric surface fastener, which includes a base fabric, hook-like engagement elements that exist on the top surface of the base fabric, and loop-like engagement elements that exist on the bottom surface of the base fabric, where a ground warp yarn and a ground weft yarn constituting the base fabric, the hook-like engagement elements, and the loop-like engagement elements are all yarns made of polyester resin, the ground weft yarn contains core-sheath type thermal adhesive polyester fibers, and the hook-like engagement elements and the loop-like engagement elements are both fixed to the base fabric by the thermal adhesive fibers constituting the base fabric.
Claims9
A fabric surface fastener of a double-sided engagement type, comprising:
- a base fabric;
- hook-like engagement elements that exist on a top surface of the base fabric;
- and
- loop-like engagement elements that exist on a bottom surface of the base fabric, wherein
- a ground warp yarn and a ground weft yarn constituting the base fabric, the hook-like engagement elements, and the loop-like engagement elements are all yarns made of a polyester resin,
- the ground weft yarn comprises core-sheath type thermal adhesive polyester fibers,
- the hook-like engagement elements and the loop-like engagement elements are both fixed to the base fabric by the thermal adhesive fibers constituting the base fabric,
- the hook-like engagement element is formed at a position where a yarn for hook-like engagement element crosses over three consecutive ground warp yarns, and
- the loop-like engagement element is formed at a position where a yarn for loop-like engagement elements crosses over one ground warp yarn.
A fabric surface fastener of double-sided engagement type, comprising:
- a base fabric;
- hook-like engagement elements that exist on a top surface of the base fabric;
- and
- loop-like engagement elements that exist on a bottom surface of the base fabric, wherein
- a ground warp yarn and a ground weft yarn constituting the base fabric, the hook-like engagement elements, and the loop-like engagement elements are all yarns made of a polyester resin,
- the ground weft yarn comprises core-sheath type thermal adhesive polyester fibers,
- the hook-like engagement elements and the loop-like engagement elements are both fixed to the base fabric by the thermal adhesive fibers constituting the base fabric, and
