Fancy yarn is a type of yarn that is different from the classical yarn structure, containing decorative irregularities in terms of color and/or form, produced by giving different effects by changing the raw material used, production and material properties.

Fancy yarns are types of yarn produced in different forms according to the fashion of the day, with appearance and aesthetic aspects predominant in addition to the yarn structure.

The development of the textile industry has directed people to obtain more different textile textures over the years.

In order to obtain fabrics with more visual features, fancy yarns with different structures that are incomparable with normal yarns have been developed. Fancy yarns have long remained a special part of the textile industry, as they are produced on special orders and have been produced for centuries mostly for decorative purposes.

These threads are generally used in a small part of textile structures.

In recent years, the positive impact of technological developments and the innovations brought by the competitive environment have played an important role in the breakthrough of this sector.

Since it is late for this newly developing branch of industry to receive sufficient attention, research on this subject has mostly focused on the factories' own products and their own machines.

Fancy yarns offer a wide variety as it depends on people's imagination.

In other words, the fact that colors and shapes can be used as much as desired shows how extensive the research of even just one type of yarn can be.

Fancy yarn types frequently used today are loop, loop, pile, knot and plain yarns.
