Unsmooth opening and closing of a slider

The gearing of the elements can be damaged by forcing a slider that does not open or close smoothly.

Apply paraffin to the front side and back of the elements and move the slider up and down several times to work in the lubricant and make the slider work smoothly.

Zipper cleaning method

A riri teeth zipper should be closed and the slider fixed before cleaning.

Left open, the tip of the stopper may damage the fabric or the tape may become stretched or may shrink.

Strong alkaline detergents or chlorine bleaching agents used to remove oil or bad stains dissolve paraffin or oily film and must be used with care. If a shiny sliver zipper does not work smoothly after cleaning, apply paraffin, and work the slider up and down several times until it works smoothly.

Methods to Determine Zipper Strength

There are various methods by which to evaluate highly polished metal zipper strength. The basic strength can be determined based on the results of the following inspection methods, from which all around strength appropriate for respective uses can be judged.

Crosswise Strength of chain (per 2.5cm)

To determine ordinary zipper strength: a zipper chain is interlocked, pulled at a fixed speed at a right angle to the chain interlocked direction, and the resistance is measured.

Vertical tensile strength of the top stop

The lower part of an interlocked zipper is fixed and the slider is pulled up to the top stop.

Holding strength is measured by pulling the slider top stop firmly.

Bottom stop tearing strength

A slider is pulled down to the bottom stop and single chains are opened to the right and left sides.

Bottom stop holding strength and resistance of the elements inside the slider are measured.

Horizontal tensile strength of the box

The open part is fixed to the tensile tester

(Only the open part as shown in the figure) so that the end of the last element falls into line with the clamp edge and the tensile strength can be measured.

Slider lock strength

A slider is locked at the middle of a zipper chain and single chains are opened to the right and left sides. Locking strength and resistance of the elements inside the slider are measured.

Overall strength of the slider (90 degrees)

For a completed slider, resistance of the slider is measured when power is put on the pull tab and the lower part of the body. In addition to the 90 degree method of measuring shown in the figure at left, there is one of 45 degrees.

How to Remove and Replace an Old Zipper Slider

Add a new zipper slider yourself by removing the existing one and replacing it with a completely new one instead of deeming the garment unwearable. Zipper sliders come with a size number located on them for identifying and matching the size needed for replacement. You don't have to have experience being a seamstress in order to do the zipper repair either. Replace your broken zipper slider by removing the old one and attaching a new one in under an hour.

Instructions

1. Acquire a zipper slider that matches the one that's broken. Locate the size number that is embedded on the zipper slider and find another with the same size indication at your local fabric supply store.

2. Remove the old zipper slider. Use the seam ripper to carefully cut the stitches that hold the fabric at the bottom of the zipper tapes, and then use a sewing needle to reveal the base of the zipper track from underneath the fabric.

3. The new zipper slider is attached properly when the zipper track opens and closes without difficulty.

The new zipper slider is attached properly when the zipper track opens and closes without difficulty.

Guide the new zipper slider onto each side of track teeth evenly from the base and pull it upward toward the top. The tracks feature longer pieces of metal than the rest of the tracks at their bases for insertion purposes. The track teeth will now be in locked position, intertwined with each other, and the zipper will now be closed.

4. Reattach the zipper foot by sewing it to overlap the track tapes with needle and thread as it was before detachment. The foot refers to the area at the bottom end of the zipper track, which is located furthest away from the space where the zipper is designed to sit in its closed position.

Tips & Warnings

Guide the bottom of the zipper track into the fabric base using your sewing needle if you experience difficulty when reinserting it back into place.

Use caution when working with the pliers, you don't want to damage yourself or the fabric.

Differences in Zipper Material

Metal zippers have been around quite a while. In fact, the first zippers were made of metal back in 1893. Metal zippers are available in different finishes:

Brass:  Chain that is constructed of brass, typically a combination of copper and zinc.

Antique Brass:  Chain made from brass that is chemically treated to give the appearance of worn or tarnished brass.

Black Oxidized: Chain made from brass that is chemically treated to a black matte finish.

Gauge

The gauge or size of the chain teeth is available in #3, 4, 5, 8 & #10. They are shown in proportion along with their respective tape width.

#5 Gauge   Actual Overall Width is 1.25"

#10 Gauge   Actual Overall Width is 1.75"
