Welcome to brain Stuff from house stuff works dot com where smart happens. H. I am Marshall Brain with today's question, why do most zippers say y k K on the poll tab? Y k K is a huge company that makes zippers. Founded in Japan in nineteen thirty four, y k K was called the Yoshita Kagyo Kabushi. I can't even say it anyway, But sixty years later the company changed its name to the much shorter y k K
to match its brand name. The privately held y k K company is headquartered in Japan and is made up of dozens of companies at hundreds of facilities in more than fifty countries. Y KK makes the entire zipper, including the dyed cloth and the brass or plastic that make up the teeth of the zipper. White KK zippers are found in clothing, furniture, automobile's luggage, sports equipment, just about
anything that has a fastener on it. A y KK factory site in Making, Georgia produces millions of zippers every day in a total of fift hundred styles in more than four seven standard colors. It's the largest zipper factory in the world. The making site produces its own brass to make the teeth and slighter parts of the zipper. The same factory also produces and dyes the yarn that's woven into the fabric portion of the zipper, and y
KK also produces the machines that make the zippers. White KK has leveraged its knowledge of working with metals to form an aluminum building products division that now it counts for two thirds of white kk's worldwide sales, So it's not just zippers anymore.
