Zippers are divided into ordinary zippers and special zippers. Special zippers are mainly used in some special occasions such as waterproof, fire prevention, reflective, sterilization, surgery, sealing and other special zippers made of special materials, special zippers are also processed by some special processing methods. Ordinary zippers refer to People's Daily life, clothes, shoes, bags, pants and other items on the use of zippers. This article mainly elaborated the zipper object is the common type zipper.
At present, there are six classifications of zipper products in the world. The biggest benefit of zipper product classification is to guide consumers to choose and use zippers correctly. Zipper is an accessory, according to different uses and highlight different functions, sometimes the product's functionality is more prominent, sometimes the decorative product is more prominent, and when the economy of the product is heavy, so the correct choice of different types of zipper, do cheap and fine, suitable function, is very important to consumers.
Product classification is ultimately important for product quality and functional testing. In the formulation of product standards, China has determined different physical performance indicators for different zipper types according to the first classification method introduced below, so that classification is more simple and convenient, and more in line with the actual needs. However, there are many countries in the world that are not clear about the classification of zippers in product standards. For example, Britain, Japan and Australia mix three kinds of zippers together, while Germany only divides zippers into metal and plastic.
1. According to the material of the chain tooth
Classification according to the material texture used in the manufacture of zipper chain teeth is a relatively common classification method in the industry at present. This classification method is very intuitive and convenient both from the production and sales of zippers, and from the promotion and use of zippers. It is a relatively acceptable classification method in all circles.
According to the material of the chain tooth, it is divided into nylon zipper, plastic steel zipper and metal zipper
2. Divide according to zipper form
By classifying the zipper in form, the function of zipper can be more clearly distinguished.
According to the zipper form, it is divided into:
A:Strip zipper: open zipper (single open, double open), closed zipper(single closed, double closed)
B:Code with zipper
3. Classify according to the combination of zipper parts
This is the classification of product refinement based on the above two categories, which highlights the individuality of zippers.
A:Change of chain tooth: color of chain tooth, type of coating, etc
B:The function change of the puller: the puller of the zipper of different material; Self - locking head, needle - locking head, non - locking head
C:Changes of pull-sheet: pull-sheet shape, pull-sheet material, pull-sheet processing technology, etc
D:The change of the stop: the material and shape of the upper and lower stop, the material and shape of the square bolt, the assembly method of the stop, etc
E:Chain belt changes: reflective, waterproof, luminous, coating, color ribbon, cotton belt, denim belt, flame retardant, lace belt and so on
4. According to the purpose of the zipper
With the refinement of the function and quality of zipper products, especially to highlight the personalized design of products, it is also an important method to choose zippers according to the use. Such as: clothing zipper, home textile zipper, luggage zipper, travel zipper, other types of zipper and so on.
5. According to the manufacturing process of the zipper
Cold stamping molding, injection molding, heating winding molding, heating extrusion molding
6. Classify the zipper by the size of the strength it bears
According to the physical properties of the zipper and the size of the closing width of the chain teeth are classified to suit different uses. Internationally, such as Britain, Germany and Japan are using such a classification method. The advantage of this method is to focus on the use of zippers, according to the strength index and size order classification, intuitive.
As can be seen from the classification of zipper products introduced above, there are many varieties and great changes in zippers. Coupled with the fact that zippers can be dyed in various colors, the production and selection of zippers become more complicated. In the selection of appropriate zipper, should be multi-dimensional detailed description of the characteristics of the desired zipper, so as not to cause unnecessary misunderstanding.
