Colouring Fabric The development of synthetic dyes in1859 made colouring fabric more predictable and greatly increased the range of colours available. A chemical known as a mordant is used to fix the colour to the fabric. Colour can be introduced at various stages during textile production. Man-made fibres can be coloured while they are in liquid form, known as spin dyeing. Fibres can be died before they are spun into yarn, known as stock dyeing. The yarn can be dyed before being made into fabric. The fabric can be dyed before being used, known as piece dyeing. Garment dyeing can be done at the end of the making process. Continuous dyeing, is also known as ‘pad dyeing’ is where the whole of the fabric is placed into a small pad bath with dye and is gently squeezed to ensure that the colour is evenly spread throughout the fabric. These are some common dyeing techniques and useful methods; BATIK DYEING: This technique works by making the fabric resist the dye, by applying wax. It originated in Indonesia on the island of Java. Batik works best on absorbent fabrics such as silk and cotton. .Synthetic fabrics do not absorb the wax or dye as easily. The fabric is stretched in a frame and wax applied using a tjanting tool or brush. The fabric is and then immersed in a cold water dye bath for some time before being allowed to dry.
