Decatising

From Wikipedia, the free encyclopedia

The aim of decatising is to stabilise the properties of the fabric developed in finishing.

In decatising, the wool fabric is interleaved with a cotton, polyester/cotton or polyester fabric and rolled up onto a perforated decatising drum under controlled tension. The fabric is steamed for up to ten minutes and then cooled down by drawing ambient air through the fabric roll. The piece is then reversed and steamed again in order to ensure that an even treatment is achieved.

There are several quite different types of decatising machines including batch decatising machines, continuous decatising machines, wet decatising machines and dry decatising machines.
