How to seduce customers to your products? At first glance, different and humanized designs can impress customers deeply. Sab’(http://www.sab-cn.com/) products include many kinds of types and each kind has its features.Zippers are always measured from "component to component" (end stops), regardless of zipper style.
Close-end zippers are non-separating and are normally opened and closed with a slider. The bottom stop is made up of a single part and doesn't allow complete separation of the chain. These zippers are used on trousers, jeans, bags, boots, etc.Open-end (separating) zippers have separated ends. The ending part is joined by a box and pin mechanism provided on the lower end of the zipper. The zippers are closed using sliders, and are normally used on jackets and other outerwear.
Two-way separating zippers have separated ends as well. But this kind has some difficulties.However, Sab’zipper factory (http://www.sab-cn.com/zipper-buttons-factory/)can solve the problems well. The bottom slider allows movement from the bottom of the zipper. These zippers are used in rainwear, sportswear, and sleeping bag. Two-Way head to head zippers have two sliders at the center of the chain when the zippers are closed. Head to head zippers can be open-end by pulling the sliders towards the stops, but cannot be separated because the ending parts have two stops that cannot be divided. These zippers are mainly used for bags, backpacks and luggage.Two-way tail to tail (back to back) zippers have sliders on opposite ends when the zipper is closed. These zippers can be opened by pulling the sliders towards each other, but cannot be separated. They are used for overalls and anything else.
Length Tolerance in Zippers : Generally zippers can vary when bulk is received due to various factors. Based on JIS-S3015 following tolerance is acceptable in zipper lengths.An all purpose zipper is the most commonly available and commonly used zipper. An all purpose zipper is a fairly lightweight zipper with small teeth. The end of the zipper has a lock which holds the zipper tape together, preventing the ends from coming apart.
It is the type of zipper you will use as a closure in most garments. Dresses, skirts, slacks and blouses are the type of weight that use an all purpose zipper. An all purpose zipper tends to bend with a garment verses a heavier type of zipper that would cause a seam to not bend or flow with the line of the garment.
New all purpose zippers are available in lengths from 4" to 24" at 2" intervals. They are available with polyester teeth or with metal teeth that match the color of the zipper tape the teeth are attached to.What’ more,as good brands for buttons(http://www.sab-cn.com/sab-button/),Sab ‘buttons also have many special kind, we will introduce them in the next passage.
