Summary of the invention
The utility model mainly is when solving half interworking of each slide fastener of the existing independent production of existing spirality slide fastener, accumulation because of the tiny error of each chain tooth spacing, make it slide fastener and cooperate easy generation both sides, back zip strip different in size, be easy to the technical problem of curling and waiting.
The utility model has also solved the existing reverse side brute force of existing spirality slide fastener simultaneously and has owed foot, and whole soft inadequately etc. technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it is by being made up of strap, left chain, right chain etc.Chain comprises one by the chain denture of continuous monofilament spirally-wound and the core rope of Qi Nei, and be sewn on the zipper strip by one or several needlework, the tooth head width h of its chain denture and the ratio of filament diameter be greater than 1.75 times, and the gap H between the chain denture and the ratio of filament diameter are greater than 1.25 times.The tooth head width h of chain denture is 1 with the ratio of filament diameter: 1.80-2.00, the gap H between the chain denture is 1 with the ratio of filament diameter: 1.50-1.65.
As preferably, the tooth head width of the chain denture of the described spirality slide fastener that is beneficial to interworking is 1.25-1.30mm, and filament diameter is 0.68mm, and the gap H between the chain denture is 1.05-1.10mm.
As preferably, the tooth head width of the chain denture of the described spirality slide fastener that is beneficial to interworking is 1.30-1.35mm, and filament diameter is 0.74mm, and the gap H between the chain denture is 1.15-1.20mm.
As preferably, after the chain denture interworking of the described spirality slide fastener that is beneficial to interworking, mean gap is 0.15-0.25mm between each monofilament.
Therefore, the utlity model has rational in infrastructure, interaction is good, the reverse side brute force is bigger, elasticity and pliability are better, and the production efficiency height can decompose the error of holding between the chain tooth, thereby effectively eliminate the accumulated error of whole piece slide fastener, solved between each strand bar when arbitrarily cooperating the unbalanced characteristics such as curling phenomenon that produce because of chain tooth spacing.
