Regional Requirement for Zipper

Normally we follow some regional requirement regarding the zipper, when we ordered or attached the zipper with body. Such as right handed zipper and left handed zipper.  This requirement also very important for fashion trend so, before place a order please be confirmed with your buyer.

How we calculate the Zipper Length.


The rules of zipper measurement is very simple but some time it becomes a matter of big trouble for us. Actually it depends on the fabric & zipper properties. So, at first we must need an idea about the shrinkage of body fabric & zipper tape. Some zipper measurements are not very complicated such as pocket, leg opening etc. Here, we only discuss about the front long zipper of sweat shirt or Jacket or as like that.

A) If the garments is hooded sweat shirt and the zipper goes up to front neck drop from bottom then the rules will as under -

Say,

Body length (From HPS) - 73 cm
Front Neck drop (CB) - 8 cm
Back Neck drop - 2 cm

(Use the below rule if the body length measure from HPS)
Rules  : Body length - (Front neck drop + Back neck drop) - 2% to 3%

           = ( 73 - (8 + 2)) -2%
           = ( 73 - 10 ) - 2%
           =  63 - 2%
           =  61.5 cm

OR

Body length (From CB) - 71 cm
Front Neck drop(CB) - 8 cm

(Use the below rule if the body length measure from CB)
Rules : (Body length - Front neck drop ) - 2% to 3%

           = ( 71 - 8 ) -2%
           = ( 71 - 8 ) - 2%
           =  63 - 2%
           =  61.5 cm

B) If the garments is high neck and the zipper goes up to to of high neck drop from bottom then the rules will as under -

Body length (From CB) - 65 cm
Front Neck drop - 6 cm
Height of high neck - 6 cm

Rules : (Body length - Front neck drop) - 2% to 3% + Height of high neck

           = ( 65 - 6) -2% + 6
           = ( 59 ) - 2% + 6
           =  57.82 + 6
           =  63.82 cm  = 64 cm

Moreover, the rules is not always remain fixed, its may vary depends on practical situations.

However, I always advise that you must confirm the zipper measurement with your cutting master & production manager before place an order

Some Important Issue Regarding Zipper

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.
