What is Yarn Dyeing?
It is the process of dyeing yarns before they are knitted or woven into fabrics. Specifically, it is the application of pigments or dyes on textiles like fibres, yarns and fabrics with the objective of giving colour with the desired colour fastness. Dyeing of fabrics is usually done in a special solution containing dyes and particular chemical material.
Yarn dyeing is used to produce multi-coloured designs such as checks, stripes and plaids. It is also sometimes used for solid colour fabrics. Some examples of such yarn dyed fabrics are brocade, gingham and weft knits. It is used in sweater manufacturing too.
In the earlier days, dyes used to be natural and were extracted from plants or animals. But then came the man-made artificial dyes and new dyeing methods which made available a broader range of colours and the dyes more stable to washing and other general use.
Different Methods Of Yarn Dyeing
There are various stages of yarn dyeing and each stage has different methods by which dyeing of fabrics is done. There is the dyeing stage before the fibres are spun into yarns and there is the stage after the yarn is ready. Some of the types of dyed garments are t-shirts, dresses, hosiery and sweaters.
Here are the different methods of yarn dyeing :
In Package Dyeing, the yarn is wound on a small perforated tube or spool which is known as a package. Multiple spools fit into the dyeing machine in which the flow of the dye bath alternates from the center to the outside, and then from outside to the center of the package.
Skein Dyeing is one of the most expensive yarn dyeing methods. It is the process of immersing large skeins of yarns that are loosely wound, into dye vats which are designed especially for this purpose. Soft yarns like hand knitting yarns are usually skein dyed.
Beam dyeing is a much larger version of package dyeing. In this method of yarn dyeing, an entire warp beam is wound onto a perforated cylinder, which is then placed in the beam dyeing machine. Here, the flow of the dye bath alternates just like in package dyeing.
These dyeing methods give the yarn their beautiful colours. In yarn dyeing, different kinds of dyes are used for different types of fibre and at various stages of the textile production process, right from loose fibres through yarn and finally to the cloth to complete garments.
