Improving raw material exploitation has become the most important challenge facing scientific and industrial community. In this paper, we have studied the effect of percentage of fibres recovered from cotton wastes and different spinning parameters on the hairiness, the uniformity and the level of irregularity of the rotor yarn. Results indicate that yarn count, rotor parameters (diameter and form) and rotor speed have an effect as significant as waste proportion. With a good choice of spinning parameters, an introduction of 25% on waste in the first passage in the drawing frame does not alter the uniformity and the appearance of rotor yarn.

The range and volume of textile products used every day is growing exponentiallythroughout the world, in both developed and developing countries. Therefore, the issues of waste Management and valorization become a challenge that requires depth economic and technical studies. In this setting, we aimed in this paper to give an added value of two kinds of textile wastes: yarns and textiles garments wastes collected from Blue denim manufacturer. A quality assessment of the reclaimed fibers shows satisfying physical and mechanical properties that allow them to be used to produce nonwoven textiles materials. A set of properties are investigated and results revealed that nonwoven structures can be considered as a good alternative for yarn and woven recycled fibers exploitation.
