March is proving a rollercoaster month, oscillating between relief at the announcement of the easing of sanitary measures and the ditching of masks in Switzerland; and the terrible events unfolding in Ukraine. No sooner had we rejoiced than the sky turned dark and today our thoughts are with those who are suffering from the conflict.
Nonetheless, nature reminds us that spring is not far away! Warmer temperatures that encourage us to open jacket zips 😉. An opportunity to take a closer look in this newsletter at an everyday object that we handle without paying attention, yet which is far more complex than it seems! So, are you ready to "unzip" this topic?
Zip fastening as we know it is a Swiss invention!
In 1891, an American by the name of Judson Whitcomb developed the first slide fastener referred to as a clasp locker and involving a set of hooks and eyes with a slide clasp serving to open and close it. But did you know that the modern zipper was first patented in Switzerland in 1893? Simon Frey, an engineer from Solothurn, developed his zipper model before World War I. Unfortunately, none of the manufacturers contacted in Germany and Switzerland wanted to buy the manufacturing rights from him.
At the same time, many inventors worked on improving the zipper. In 1914, an American-Swedish man named Gideon Sundback patented the modern version of the zip fastener, which consisted of small interlocking teeth with an integrated slider.
In 1923, Martin Othmar Winterhalter from eastern Switzerland bought the patent from Sundbäck. In 1936, he founded Riri AG in Mendrisio (IT), which is still one of the world's leading companies in this sector.
The zip, a matter of teeth, chain, pulls and sliders
The manufacturing process for a zip consists of two distinct phases: on the one hand, the production of the small teeth that will be used to produce the chain. These are obtained by a process of shearing the brass plate. On the other hand, the production of the pulls and sliders involves die-casting: the material used is ZAMAK, an alloy of zinc, aluminum, magnesium and copper. It melts at 420 degrees Celsius and is injected into steel molds.
Chain width, finishing, galvanization, customization, type and number of pulls… There is a vast range of zips and the choice is not always easy.
The different types of zippers
* Separable zips: Separable zips have two detachable sides. They are generally used for jackets or cardigans.
* Non-detachable zippers: in this case, the two tapes are joined at the base. Non-separable fasteners are used for trousers, jeans, jumpers, polo shirts, etc.
There are also specific fasteners:
* Waterproof zippers: this type of zipper involves special treatment of the tape and the mesh that makes it waterproof and thus serves to make rain jackets or waterproof suits.
* Double-slider zippers: as the name suggests, double-slider zippers have two independent sliders serving for example to open and close a parka. The bottom can then be opened for more comfort when seated. It can also be opened on a belt.
* Invisible zippers: these are very thin and blend in perfectly with the garment. Invisible fasteners are practical and maintain the smooth design.

Caring for your zipper 100% Made in Italy
We take great pride in the quality of our zippers, which are, like everything else, 100% Made in Italy! However, just as with anything of this high caliber, care is essential, and here are a few tips on how to maintain them in perfect working order:
* When ironing, make sure to close the zippers.
* When ironing, protect your zippers with a cloth, and avoid using a hot iron on the chain and the zip pull so as to protect the galvanization.
* To clean a zipper on a garment that cannot be machine-washed, brush the stitches with a dry toothbrush so as to remove any encrusted dust.

INEVITABLE PRICE ADJUSTMENT
Since the launch of KA/NOA almost five years ago, we have been striving to charge prices in line with the quality we offer, applying low margins that are respectful of both our work and our customers. Like many other companies, we are currently suffering the full force of rising raw material prices (the price of Egyptian cotton has increased by 100%) and rising production costs... Despite our efforts, we are now forced to adjust the prices of certain products, but we do so in the spirit and philosophy we have cultivated from the outset and which will continue to drive us throughout this project.
