Abstract
A curved slide fastener chain and a method for producing a curved slide fastener are disclosed. The curved slide fastener chain comprises a pair of fastener tapes and a plurality of fastener element rows planted on each of a pair of the fastener tapes. Each of the element rows includes a straight and a curved inter-engagement portion. The curved inter-engagement portions are dis-inter-engaged while the straight inter-engagement portions are inter-engaged, so that each of the pair of fastener tapes are able to extend in a straight line. Therefore, deformation of the curved inter-engagement portions due to heat and tension applied thereto during the washing, dewatering and drying steps in producing a curved slide fastener can be prevented.
