- this knitted fabric is used for a textile product that is used in a cut portion without treatment, fraying of the edges is less likely to occur even after repeated wearing and washing.
- Patent Document 2 At least one row of cut regions extending along the longitudinal direction of a base fabric composed of ground wefts and ground warps and serving as ears of cut pieces after being cut is formed. A selvage anti-fray fabric is disclosed. Further, Patent Document 3 discloses a textile product which is a woven fabric composed of polyurethane fibers and other synthetic fibers and which is treated to prevent fraying.
- Patent Document 4 discloses that by heat-treating heat-sealable elastic fibers such as polyurethane fibers, misalignment, fraying, run, curling, etc. are difficult to occur, and fraying prevention that can be used as a product even if it is cut off.

- a leno weave structure is hard and has a poor texture, it is not suitable for use as a clothing material itself.
- the textile product described in Patent Document 3 is applied to fabrics using polyurethane fibers and other synthetic fibers, and is subjected to adhesive sewing, ultrasonic fusion cutting, piping treatment of cut edges, and wrapping using sealing tape. It is obtained by performing anti-fraying treatment such as embedding treatment. That is, it is nothing more than a conventional fabric subjected to a known fraying treatment, and the fabric itself does not have any anti-fraying properties.

The woven fabric of Comparative Example 2 was woven with a core-sheath type composite yarn made of the same material as in Comparative Example 1, that is, a covering yarn using a polyurethane yarn as the core yarn and a nylon yarn as the sheath yarn. However, the fineness of the core yarn was 44 dtex, and the fineness of the sheath yarn was 78 dtex. Therefore, the CS value is 0.564. Also, the number of twists was 700 T/M.
