Blended yarns are spun using staple fibers which consist of two or more types of fibers.

These yarns can be a combination of the following:

- polyester fibers

- cotton fibers

- viscose fibers

- acrylic and modacrylic fibers

- wool fibers

- Modal / Micromodal fibers

- Tencel fibers

- bamboo fibers

- flax fibers

- polyamide fibers

- polypropylene fibers

- antistatic fibers (steel, carbon, aramid)

Blends were introduced to the market with the development of synthetic fibers which were cheaper than natural ones and had new interesting physical properties.

Blended yarns can be produced using the following basic spinning methods:

Fibers of various types for the production of blends are blended in two basic ways:

 - at the blow-room stage (loosening the fiber with compressed air) - it is a more complicated and more expensive system. The fibers are blended very evenly and as a result there are no problems with obtaining the mélange effect using only one type of dye.

- at the draw-frame stage (stretching and multiplying fibers) - it is a less complicated and cheaper system, but the it is exposed to uneven distribution of fibers and possible later problems with obtaining the mélange effect using only one type of dye (shades and streaks).
