Some Important Issue Regarding Zipper

When we will use zipper in a body, we must be careful regarding some points. Because any wrong selection in this process can be reject your garments. We must be considering each & every points before place a work order of zipper. Also we must be test everything before start joining with the body.

Always we should keep a thing in our mind that, the characters of zipper is not similar with our garments. So we always should try for better adjustment.

The main material of zipper is teeth. The Zipper teeth are usually made of brass, aluminum, plastic or nylon and shrinkage of these items is very low. These items do not shrink when washed.

Therefore, the zipper tapes must be made of materials which do not shrink when washed otherwise the shrinkage will make the zipper fail to function. In most cases, the zipper tapes are made of nylon or polyester which do not shrink and are colorfast. 

When we order zippers we should specify that, the zippers (teeth and tape) are color fast, and order them in colors to match the garment color after wash.

The colors of pigment dye fabric, garment dye fabric, garments or denim garments may change substantially during the washing process. If your zipper colors match them before wash, you will end up having the zippers much darker than garments colors after wash.

If it is a long zipper like the front zipper of a Jacket, you have to make sure the shell fabric you use is of maximum 3% shrinkage otherwise when the garments shrinks in washing and the zipper does not shrink, the zipper will become wavy making it difficult for the zipper slider to go up down. Besides, a wavy zipper will make the garments look bad.

Also before place a order you should have clear idea that, you are ordering left handed or right handed zipper. Because, very often buyer asked for different handed zipper for male & female.

I personally advise all the merchandiser that, you must fix the zipper length after discussion with your production people otherwise you may get in trouble.
