- Annotation: The results of the experiments showed that with an increased density of raw cotton that occurs in the lower layers of the bundle and an increase in its shelf life, an increase in the mass fraction of defects and trash in the fibre is observed. It was found that with an increase in the density of raw cotton more than 250 kg/m3, the mass fraction of defects and weeds in the fibre increases by almost 10 %, the damage to seeds by 6 %, the staple mass length decreases by 3 %, and the proportion of short fibres by 9 %. The increase in the shelf life of the fibre also negatively affects the quality of the fibre and seeds and, most importantly, cotton for grades III–V. An increase in the mass fraction of flaws and trash in the fibre, in turn, affects the unevenness of the yarn and the quality category of the resulting yarn.
