Abstract
A method for manufacturing the copper zipper with reinforcing rib and improved slide smoothness and firmness features that the original central 4*6 yarn line on the side cloth belt is changed to be braided central line, the original bound edge technology (1.2 mm) is changed to serging one (2-3 mm) for playing the role of reinforcing rib, and the weft density of said belt is changed from 44.9 to 42.3.
Description
Technical field [0001] The invention relates to a copper zipper, in particular to a copper zipper with reinforcing ribs, belonging to the technical field of zipper manufacturing. Background technique [0002] Compared with nylon zippers in our daily life, copper zippers of known technology are strong, rust-free, beautiful and durable, and are used in a large amount on many denim garments. However, the copper zippers made in my country are in the middle of the quality level. Defects are mainly manifested in four aspects, 1. Metal belt weft density; 2. Zipper feel and smoothness; 3. Strip zipper flatness; 4. Flat pull strength of zipper tape. Reference document 1 of this patent application, Chinese Patent No. 200420075429.9, application date 2004.12.20, announcement date 2005.12.21, discloses a metal zipper. Reach the flat tensile strength of copper zipper. Reference document 2 of this patent application, Chinese Patent No. 98241899.X, application date 1998.11.02, announcemen...
