Embodiment

[0077] Examples of the present invention are shown below, but these examples are provided for better understanding of the present invention and its advantages, and are not intended to limit the present invention.

[0078] Nylon 66 (polyhexamethylene adipamide) having a melting point of 265° C. was used as the polyamide resin (PA) in the example. The melting point of the polyamide resin was determined using DSC EXSTAR6000 (manufactured by Seiko Instruments Inc.) at a sample size of 5 to 10 mg, N 2 Measured in a gas environment with a heating rate of 10°C / min. In addition, polybutylene terephthalate (Toraycon 1101G30) was used as the resin of the comparative example.

[0079] As the reinforcing fibers, glass fibers (GF) having an average fiber diameter of 11 μm, an average fiber length before molding of 3 mm, and an average fiber length after molding of 0.25 mm were used. As the pigment, zinc sulfide (ZnS) having a Mohs hardness of 3 and a refractive index of 2.4 was used.

Abstract

The present invention provides a slide fastener component comprising a molded part made of a polyamide resin composition containing reinforcing fibers, a dyed layer arranged inwardly from the surface of the molded part, and the thickness of the dyed layer is 30 to 100 μm.

Description

technical field [0001] The present invention relates to a slide fastener component, a slide fastener, and a method for manufacturing the slide fastener component. Background technique [0002] Not only daily necessities such as clothing, bags, shoes, and miscellaneous goods, but also zippers are used as opening and closing parts for industrial supplies such as water tanks, fishing nets, and space suits. [0003] It is known that in a zipper whose elements are made of resin, zipper components such as elements, sliders, top and bottom stops, and opening elements among the structural parts of the zipper are usually molded parts manufactured by injection molding, and poly Ester resin and / or polyamide resin is used as a material for manufacture. Furthermore, it may be desirable to dye these molded parts in a desired color in order to improve the appearance. [0004] In this regard, Patent No. 4517277 (Patent Document 1) describes an invention that aims at making the appearance ...
