Which polymer is used for the manufacture of wash and wear clothes?

terylene fibres

The correct answer is option 3. terylene fibres.

Terylene is a type of polyester fiber that is commonly used in the production of textiles and clothing. It's a synthetic polymer made by combining ethylene glycol and terephthalic acid through a process called polymerization.

One of the key characteristics of terylene fibers is their durability and resistance to wrinkles. Unlike natural fibers like cotton or wool, which can easily wrinkle and lose their shape after washing, terylene fibers have a natural resilience that helps them maintain their smooth appearance. This resilience also makes them resistant to creasing during wear, contributing to their "wash and wear" properties.

Additionally, terylene fibers have good moisture-wicking properties, which means they can effectively transport moisture away from the body, keeping the wearer dry and comfortable. This makes terylene garments suitable for a wide range of climates and activities.

Terylene fibers are also relatively easy to care for. They can be machine washed and dried without losing their shape or color, and they typically require minimal ironing, if any, due to their wrinkle-resistant nature.

Overall, terylene fibers are favored for wash and wear clothing due to their durability, wrinkle resistance, ease of care, and ability to maintain their appearance even after repeated laundering.
