In the case of open-end yarns, the fibers in the yarn structure show an irregularity due to the production method. However, this irregularity continues throughout the yarn. This uneven structure continues through the yarn. Resistance to abrasion is higher in high twisted species. It has a higher abrasion resistance up to 7 percent than ring yarn.

Open end yarns are more bulky and have high absorbency. Flexural properties are stronger. Because of these properties, it is possible to obtain bright tones and print patterns on fabrics. In addition, heat retention and air permeability are better than ring yarns. One drawback, however, is that 20 percent lower tenacity than rotor-spun yarns.

The use of open end yarns is becoming more common every day. Especially in trousers, jeans, young clothing, children's clothing and sportswear fabrics, more preferred.

Long fibers of cotton are used in ring yarn production and are mainly divided into carded and combed. The difference is due to combing. In the combing process, the cotton is subjected to a dense combing process in the machine and the short fibers of the cotton are separated. The difference of combed yarn from carded yarn is the use of longer fibers obtained in the production after combing. In this way, much finer yarns are produced. These high-quality yarns are soft and have high absorbency. It is mainly used in the production of shirts, underwear and linens.

Carded and combed yarns are of higher quality than rotor-spun yarns. It has a softer and flat texture compared to rotor-spun yarn as it provides integrity with fewer twist counts during production. In addition, hairs and deformation are less common in fabrics produced from these yarns.

In the accredited laboratories, rotor and ring yarn analyzes are performed in accordance with the standards issued by domestic and foreign institutions. The standard taken into consideration in these studies is the Ekoteks 2 standard.
