  • Fastener Chain with Separable Bottom End Stop and Method for Producing the Same
    Publication number: 20130305499
    Abstract: There are provided arc a fastener chain with a separable bottom end stop capable of increasing the reinforcement force of a portion to which the separable bottom end stop is attached—without using a reinforcing tape and keeping aesthetic appearance, and a method for producing the fastener chain. The fastener chain includes reinforced portions into which a curing adhesive has penetrated and cured, and has a misalignment-free strength of 100 N or more at the reinforced portion. The method for producing a fastener chain includes preparing a fastener chain including a plurality of element intermittent portions, attaching separable bottom end stop to each of the element intermittent portions, impregnating each of the element intermittent portions with a curable curing adhesive having a viscosity of 100 to 2,000 mPa S and a curing the curing adhesive which has penetrated into the element intermittent portions.
