Zipper
This article is about the fastening device called the zip. For other uses of the word "zip", or the acronym "ZIP", please see the disambiguation page.A zipper (zip fastener or zip in British English) is a device for temporarily joining two edges of fabric together. It is widely used in clothing, bags and suitcases, purses, tents, sleeping bags and other textiles.
Alternatives that are also frequently used are buttons, Velcro, laces and buckles.
Description
The bulk of a zip consists of two strips of fabric tape, one permanently fixed to each of the two flaps to be joined, and each carrying tens or hundreds of specially shaped metal or plastic teeth. Another part, the slider, which is operated by hand, rides up and down the two sets of teeth. Inside the slider is a Y-shaped channel that pushes the opposing sets of teeth together or apart, depending on the slider's direction of travel. The friction of the slider against the teeth causes a characteristic buzzing noise which is probably the origin of the name zip.Some zips have slides on both sides, allowing one to vary not only the size, but also the position of the opening.
Applications of zips in clothing:
- to connect and disconnect the left and right front side (usually fitted vertically so that pushing the slider from top to bottom opens it, and pushing it from bottom to top closes it)
- to widen an opening:
- the zip in the fly is additionally used by men for urination without taking the trousers down
- to open and close pockets
- for attaching/detaching a hood and legs of trousers
- for decoration
