PROBLEM TO BE SOLVED: To provide a fastener product made of a synthetic resin which is excellent in resistance to heat and humidity and to a hydrolysis, and can be maintained in a stable engagement situation without deteriorating in strength even under repeated conditions into high temperature and humidity, in addition, can be recycled into regeneration. SOLUTION: Components for the fastener product made of the synthetic resin such as a slide fastener, a hook-and-loop fastener, and snap buttons with a tape, are made of a hydrolysis resistant synthetic resin material, especially of a synthetic resin material blended with a carbodiimide anti-hydrolyzing agent. In the case of the slide fastener 1 fixed with chuck elements 4 along an edge section of a fastener tape 3, the fastener tape and the chuck elements are made of the hydrolysis resistant synthetic resin material. In addition, upper and lower stoppers provided on upper and lower ends of the chuck elements, an opening/ fitting piece and reinforcement sheet members of an open type slide fastener, and sewing threads and core strings in the case of a consecutive chuck elements, are made of the hydrolysis resistant synthetic resin material in the same way as the components. |
