What is Yarn and Types of Yarn?

Yarn is the fundamental unit of fabric. It contains so many characteristics or properties (variables) which can affect on finished quality of the knit fabric. The quality of hosiery yarn has to be considered with due weightage to the fluidity of knitted structures and their influence on the quality of knitted fabrics. According to processing, there are mainly three types of yarn which are explained in this article.

Combed and carded yarns of the same count have so many different characteristics due to various manufacturing processes. Carded yarn is of inferior quality and combed yarn is of superior quality.

In another word, a yarn is an assembly of different fibers or the same fibers which are laid or twisted together for producing a continuous strand.

It should be noted here that, yarn can be produced by using filament fibers or staple fibers. Filament fibers have needed a little or no twist to hold them together into yarn. On the other hand, staple fibers are twisted to form into yarn.

Classification of Yarn:

There are mainly three types of yarn according to processing in the spinning industry. Those are in the following:

  1. Carded yarn,
  2. Combed yarn,
  3. Semi-combed yarn.

All the above types of yarn have explained the below:

1. Carded Yarn:

Carded yarn is the worst quality type of yarn. Normally, this type of yarn contains more neps and more short fiber. No comber has needed during cared yarn manufacturing in the textile spinning sector.

2. Combed Yarn:

Combed yarn is one of the superior qualities of yarn. This type of yarn does not contain any short fiber and neps. During manufacturing combed yarn, the combing process plays an important role. Without the combing process, the manufacturing of combed yarn is not possible.

3. Semi-combed yarn:

Semi-combed yarn is a medium quality of the yarn that is produced by mixing some combed slivers. One example is enough to understand about the semi-combed yarn and that is- if there are 8 slivers 4 carded and 4 combed slivers are mixed at post comb draw frame then it’s called 50% combed sliver.
