A method for manufacturing a fastener stringer according to the present invention, include a dyeing step for dyeing a fastener stringer including an element row fixed to a side edge portion of a tape made of fiber, a dye cleaning step for removing excess dye from the fastener stringer, a water repellent treatment step for adhering a non-fluorine-based water repellent agent to the fastener stringer, and a pre-dyeing degreasing step for degreasing oil and fat adhered to the fastener stringer by a wet process.

Method for manufacturing fastener stringer

A knitted fastener stringer has a chain stich yarn disposed on the innermost edge wale furthest from the tape body portion of an element attaching portion is the thickest of all the chain stich yarns used in a fastener tape. This enables a distance of a gap formed between left and right fastener tapes to be smaller when a slide fastener is formed by two knitted fastener stringers.
