The size of the zipper and the precautions for using the zipper

The base of the zipper head will have specifications such as 3, 5, and 8, which represent the slider of the 3# zipper, the slider of the 5# zipper, and the slider of the 8th zipper. The size parameters of the zipper head include mouth height and mouth width, which represent the width and height of the zipper head, respectively. The size of the model is proportional to the size of the zipper teeth. A zipper consists of teeth, sliders, upper and lower blocks (front and rear) or cleats.

The sprockets are the key part. It not only determines the side pull strength of the zipper, but also the size of the zipper. Generally, the zipper has two chain belts, each chain has a row of elements, and the two rows of elements are staggered. The fasteners on both sides are clamped by the slider, and the fasteners on both sides can be engaged or disengaged by sliding with the pull tab.

1. Color transfer

Some special material layers on the surface of the zipper or the dark color of the zipper may stain light-colored fabrics in some cases. For example, color transfer can occur when polyester tapes dyed with disperse dyes come in direct contact with adhesives or oils from synthetic leather or PVC tapes.

Tips

Put a sheet of paper between the zipper and the fabric to avoid color transfer due to temperature, pressure, humidity or prolonged contact.

2. Copper oxide

Metal zippers coated on felt will turn black due to oxidation. Chemicals and bleach left over from leather or wool products can release gases that react with metal zippers, causing them to discolor. In addition, if the metal zipper is tied by a rubber band containing sulfide, vulcanization will also occur.

Tips

Considering the oxidation of metal, although the electroplated zipper puller has been rust-proof, please wrap it with special paper to reduce discoloration and scratches.

3.Washing

Wash the zipper and secure the slider before washing the cloth, otherwise the slider may scratch the fabric and the tape will shrink.

Tips

Note that strong cleaners and chlorine-based bleach will dissolve paraffin and oil films on the surface of the zipper. If the zipper is difficult to open and close after cleaning, apply soap or other lubricant to your teeth and close the zipper a few times. Painted sliders should be cloth wrapped before washing to prevent the paint layer from peeling off.

4. Ironing

The ironing temperature should be adjusted according to the material of the fabric, and the ironing zipper is also suitable. Ironing the zipper at the proper temperature will keep it looking normal and looking good.

Tips

Before ironing, close the zipper, hold the slider in place and level, and cover the zipper with a cloth. Do not touch the zipper directly when ironing.

5. Stuck Zipper

When the zipper is jammed and the zipper is unzipped, sometimes the slider gets stuck on the fabric. In this case, trying to move it with more force will make it worse. What you should do is remove the stuck fabric piece and pull the slider back with little force. Also pay attention to the smoothness of the zipper when sewing.

Tips

Make sure the zipper is fully open when putting on or taking off clothes, preferably button or hook the pants before zipping
