Ironing

[2] Ironing works by loosening the bonds between the long-chain polymer molecules in the fibres of the material.

While the molecules are hot, the fibres are straightened by the weight of the iron, and they hold their new shape as they cool.

Permanent press clothing was developed to reduce the ironing necessary by combining wrinkle-resistant polyester with cotton.

On 15 February 1858 W. Vandenburg and J. Harvey patented an ironing table that facilitated pressing sleeves and pant legs.

[9] Commercial dry cleaning and full-service laundry providers usually use a large appliance called a steam press to do most of the work of ironing clothes.
