Job Details

Hook and loop systems are essentially comprised of two components: a "hook" side and a "loop" side. The hook side is rougher and filled with very tiny hooks. The loop side is less coarse with clusters of hairy loops. When these two components are pressed together, the hooks catch the loops and bind the strips together. The strips are easily separated by pulling or peeling them apart, which creates that distinct ripping noise synonymous with touch fasteners.

The inspiration for hook and loop fasteners came from an unlikely source: seeds and dog hair. Back in 1941, Swedish electrical engineer by the name of George de Mestral went on a hunting trip with his dog. Throughout their outing, De Mestral was constantly yanking cockleburs seeds off of his clothing and his dog's fur. Like any good scientist, De Mestral put the seeds under a microscope and saw that the seeds were covered with hundreds of spiny hooks that attached to anything with a loop.Before going over the difference between hook and loop, it’s important to note that what most people consider “Velcro” is a product called hook and loop. “Velcro” is a brand, called the Velcro Companies, and they are the original manufacturer of hook and loop fasteners.Hook and loop fasteners consist of two distinct pieces. The rough, scratchy side is the hook because it is covered with several tiny hooks per square inch. Likewise, the soft, fuzzy side is the loop because it is covered with many small loops. The hooks engage the loops when the two sides are pressed together. This creates a bond that is exceptionally strong and allows for repeated use that lasts for thousands of cycles.First, let’s get a picture of the type of cable ties available. The table below is by no means exhaustive, as there are subsets of cable ties within this table. For example, standard cable ties can be weather resistant, which gives them different applications than their cousins’.

Standard cable ties are a fantastic all-rounder, but when you need something more specialized, such as heat-proof cable ties, industrial-strength cable ties, or solutions with excellent resistance to UV rays, you can get those too.

Properties of fibers and fabrics that contribute to human comfort

Comfort characteristics of cloths are made by a collection of interactive properties of fibers, yarns and the fabric which have contributed in construction of the clothing. This chapter focuses on the main affective properties of fibers, yarns and fabrics. It starts with fiber specification, comparing two natural and synthetic sources of fibers used in apparel textile products, and then investigates physical treatments to modify fiber properties. The chapter continues with yarns and fabrics as the intermediate products to cloths, investigating the producing parameters which create and affect garment comfort.
