Polyester is made of repeating units of a chemical called ester. Polyester is often used in pants, shirts, suits, and bed sheets either by itself or as a blend, because of its wrinkle-resistant property and its ability to retain its shape.

Terylene is a popular polyester which is used in dress materials.
PET (Poly Ethylene Terephthalate) is another example of polyester. It is used for making bottles, utensils, films, wires and many other items.
Polyester fabrics do not wrinkle easily and are easy to wash.

Grease and oil is also called lubricants ? Why

Posted by Albey Jacob 7 years, 9 months ago

CBSE > Class 08 > Science

1 answers

Yogita Ingle 7 years, 9 months ago

When oil or grease is applied between the moving parts of a machine ,a thin layer of oil or grease is formed between the two rubbing surfaces. This layer of oil separates the two rubbing surfaces a little bit due to which their interlocking is reduced to a large extent.This friction is reduced and movement becomes smooth.When oil or grease is applied to the moving parts of a machine, then their surfaces do not rub directly against each other, they rub through a layer of oil and grease .
