Abstract
A slide fastener is characterized in that left and right first and second element rows thereof are composed of synthetic resin, with each being dyed a single color having a different spectral reflectance curve from each other. The slide fastener appears colorful and attractive and has an excellent appearance quality since the colors of the first and second element rows can be made to appear more vividly.

A slide fastener comprising a pair of fastener stringers in which a first element row and a second element row are respectively formed at facing tape side edge portions of a first fastener tape and a second fastener tape, being characterized in that the first element row and the second element row are made of synthetic resin and are respectively dyed in single colors, and the first element row and the second element row have spectral reflectance curves which are different from each other.
A manufacturing method of a slide fastener having a pair of fastener stringers in which a first element row and a second element row are respectively formed at facing tape side edge portions of a first fastener tape and a second fastener tape, wherein the method includes
- dyeing a first monofilament made of synthetic resin in a single color,
- dyeing a second monofilament made of synthetic resin in a single color which has a different spectral reflectance curve from the first monofilament,
- molding the first monofilament and the second monofilament to the first element row and the second element row respectively, and
- sewing the first element row and the second element row to the tape side edge portions of the first fastener tape and the second fastener tape respectively with sewing threads.
