Knitted fabrics / T-Shirts

In the knitting sector – for which rotor-spun yarns initially seemed out of the question due to their harsh hand – they have been able to establish themselves on a broad basis, despite all doubts. Some minor differences in hand still certainly exist, but these can virtually be offset by appropriate finishing. Furthermore, there are sufficient knitted fabrics for which the hand is an important, but not the crucial criterion. This range of application is successfully served by soft-twisted, hairy and bulky rotor-spun yarns.
These include, for example, T-shirts made from single jersey, where rotor-spun yarns have secured significant market share. Differences in yarn regularity and imperfections are immediately and very clearly apparent in single jersey. With their superior regularity and significantly fewer imperfections, rotor- spun yarns are therefore positively predestined for this application. Very uniform fabric appearance with high and good pile density due to the bulky nature of the yarn upgrades the knitted fabric through the use of rotor-spun yarns. Soft hand and high hairiness (if required or necessary) can reliably be achieved by appropriate spinning equipment ( draw-off nozzles with a large number of notches and eddy inserts in the nozzle throat). Modern finishing methods also enable yarn properties to be significantly improved further, especially as regards the softness and suppleness of the knitted fabric. A further advantage of circular knitted fabrics made from rotor-spun yarns which should not be underestimated is that the knitted tubes do not twist as they do with  ring-spun yarns. Making-up knitted tubes made from rotor-spun yarns is therefore much more problem-free than is the case with ring-spun yarns.
