Reduced Yarn Stress During Knitting Helps Avoid Thread Breakage

By its very nature, circular knitting is highly productive and therefore the most cost-effective way of producing textile surfaces. The reason for this lies in the continuous circular movement. Development engineers have always striven to extend the mechanical limits of revolutionary speed. In the case of circular knitting, the yarn is the factor which sets the limitations here. A thread has a certain stress limit at which it ruptures.

Reduced Yarn Stress During Knitting

Consequently if a way can be found to lower the level of stress, yarn breakages will be reduced to a minimum, resulting in higher rotational speeds. By causing the needles and sinkers to move in relativity to each other, it was possible to half the number of yarn deflection points occurring during the knitting process. As every deflection equals friction and thus increased stress on the yarn, it is easy to see how relative movement technology with just 4 deflection points in the stitch forming area (compared to 8 deflection points using conventional knitting single jersey technology) was instrumental in bringing about a decisive reduction in yarn stress.

Fewer yarn deflection points during stitch formation = Less friction = Lower stress on the yarn.

The result:  Minimized yarn breakage
