Plastic coils, with heat-resistant base part and useful for slide fasteners, were prepd. in a continuous process by winding synthetic monofilaments around a mandre land heatsetting the base part of the coils. Thus, a coil was formed from nylon 66 monofilaments and the base part of the coil was heat-treated 1-2 sec at 210-260≦̸C to give a coil useful for slide fasteners.
