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.

A reusable closure system for providing easy closure and opening of an object such as a sheet forming a barrier. The reusable closure system generally includes a backing member adapted to be secured to an object, such as by an adhesive. A closure member may be connected to the backing member, with the closure member including a first portion which is removably connected to a second portion by one or more magnets. An optional outer closure member may be connected to the closure member, with the outer closure member including a zipper. Thus, the reusable closure system may be secured to various objects to allow for selective opening or closing of the objects in a versatile, user-selected manner.

Fastener stringer may include a knitted fastener tape, and a fastener element attached to the fastener tape. The fastener tape may include a first side-edge portion where the fastener element is provided, a second side-edge portion provided at an opposite side of the first side-edge portion, and a tape main portion provided between the first and second side-edge portions. The first side-edge portion may include one or more chain-stitch yarns formed in one or more wales. The second side-edge portion may not include a chain-stitch yarn. The tape main portion may include M or more chain-stitch yarns formed in M or more wales. M may indicate a natural number equal to or greater than one third of the total number of wales included in the fastener tape. Difference in yarn density may be caused between the tape main portion and the second side-edge portion.

A zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape, wherein compaction of the two tapes uses a compactor, and wherein the compactor comprises at least one drum, wherein the drum comprises a notch or groove to allow the zipper's interlocking elements to pass without pressure from the drum while the tapes on either side of the interlocking elements are being compacted.
