Easily dyed, strong, light weight, and resistant to shrinking, stretching, mildew and creasing. Sun resistant.

Main disadvantage is that Polyester does not breathe. Fabric shine can be unattractive. Stains are difficult to remove. Not environmentally friendly.

Polyester is used in the manufacturing of all kinds of clothes and home furnishings like bedspreads, sheets, pillows, furniture, carpets and even curtains. The disco clothing of the 70s with all its jazz and flash was made of polyester.

By creating hollow fibers it is also possible to build insulation into the polyester fiber. Air is trapped inside the fiber, which is then warmed by the heat of the body.

Silk is produced by several insects, but generally only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level.^[2] Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects such as webspinners and raspy crickets produce silk throughout their lives.^[3] Silk production also occurs in Hymenoptera (bees, wasps, and ants), silverfish, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies, and midges.^[2] Other types of arthropodproduce silk, most notably various arachnids such as spiders.

The word silk comes from Old English sioloc, from Greek σηρικός serikos, "silken", ultimately from an Asian source (cf. Chinese si "silk", Manchurian sirghe, Mongolian sirkek).^[4]
