Dyeing

There are several different ways of dyeing fabrics:

  • stock or yarn - dyes the fibres before they become fabrics
  • piece - dyes pieces of fabric
  • garment - dyes clothing once it is made

Dyeing usually takes place in large before being heated and dried.

Printing

Commercial printing prints pattern onto the top surface of fabrics. There are a variety of printing methods available:

Screen printing

A screen with the stencil of the pattern has dye wiped over it to produce an accurate, repeatable print. A separate screen for each colour is required.

Roller printing

Roller printing can be used for long, striped patterns. A roller for each colour has a pattern on it. As the fabric passes through, the pattern is added.

Sublimation printing

is printed onto coated paper. Once heated, the image is transferred onto fabric.

Digital printing

Digital printing allows fabric to be printed on directly from an inkjet head. It is expensive but offers a wide range of colours.
