A slide fastener chain includes first and second rows of coupling elements mounted on first and second longitudinal edges of the first and second fastener tapes. When the first and second rows of coupling elements are interdigitated, the first and second longitudinal edges remain spaced apart, and a first coupling element of the first row is received between two adjacent coupling elements of the second row such that: the groove of the first coupling element receives, in a first contact region, a portion of the second longitudinal edge, one of the grooves of the adjacent coupling elements receives, in a fourth contact region, a first portion of the first longitudinal edge, and another of the grooves of the adjacent coupling elements receives, in a fifth contact region, a second portion of the first longitudinal edge.

A sealed zipper assembly includes a first zipper segment and a second zipper segment in overlapping relation to create a sealing zone. A sealing element is positioned in the sealing zone to prevent leakage between the first zipper segment and the second zipper segment.

Provided is a waterproof airtight zipper with double zipper sliders, including an upper waterproof zipper part and a lower waterproof zipper part; a lower edge of the first top stopper and an upper edge of the second top stopper are fixedly connected as an integral intermediate sealing structure; the intermediate sealing structure is located between both the zipper sliders of the upper waterproof zipper part and the lower waterproof zipper part and is arranged in a disconnected manner; and an opening is formed at the intermediate sealing structure. A form of double zipper sliders is adopted to make left and right ends stressed at the same time, so that it is more labor-saving to pull open the zipper; the way of pulling open the zipper bidirectionally facilitates operation and use; and the intermediate sealing structure can ensure the air tightness effect of the waterproof sealing zipper.

A water repellent product includes a water repellent fabric in which a non-fluorine-based water repellent agent is applied to a fabric formed of a fiber; and a resin component attached to the water repellent fabric. The water repellent product contains substantially no cross-linking agent for chemically bonding the non-fluorine-based water repellent agent and the fiber.
