Disclosed is a fastener stringer where at least one surface of each of the fastener elements is colored. A plurality of fine fixing spaces is disposed on at least one surface of the fastener element which is colored. Accordingly, when a slide fastener is colored through an inkjet method, ink droplets ejected to the fastener element may be received by a plurality of fixing spaces and stably fixed onto a surface of the element. Consequently, a desired pattern or color can be continuously given to a fastener tape or the fastener element, and the contour of the pattern or color can be formed clearly and neatly.

Fastener stringer and slide fastener

A fastener tape includes a tape main body portion and an element attachment portion in which a core thread is knitted. The tape main body portion includes a first tape main body portion region at the element attachment portion and a second tape main body portion region. A wale interval between a wale of the element attachment portion adjacent to the first tape main body portion region and a wale constituting the first tape main body portion region is narrower than that of the second tape main body portion region. Therefore, while the flexibility of the second tape main body portion region is ensured, a tape strength and an abrasion resistance are improved, and further, when a fastener element is formed, this prevents resin leakage through knitted loops of the element attachment portion.
