Abstract
A method of reducing torque in garments includes calculating a needle wale skew measurement for the fabric. A knitting machine can orient fabric along its negligible torque line. The knitting machine includes a cylinder having a plurality of needles for knitting the fabric, a take-down component for pulling the fabric from the cylinder, and the knitting machine is adapted for rotating the take-down component at a predetermined rotation ratio relative to rotation of the cylinder. The predetermined rotation ratio can be calculated using the needle wale skew measurement. Torque can be accurately measured at all textile/apparel processes.
Claims20
A method of producing a fabric having a desired torque comprising:
- (a) calculating a needle wale skew measurement for the fabric to be produced;
- (b) providing a knitting machine comprising a cylinder having a plurality of needles for knitting the fabric and a take-down component for pulling the fabric from the cylinder, and wherein the knitting machine is adapted for rotating the take-down component at a predetermined rotation ratio relative to rotation of the cylinder;
- and
- (c) calculating the predetermined rotation ratio based on the needle wale skew measurement.
A knitting machine comprising:
- (a) a rotatable cylinder having a plurality of needles for knitting the fabric;
- (b) a take-up section comprising a rotatable take-down component for pulling the fabric from the cylinder;
- and
- (c) the knitting machine adapted for rotating the take-down component at a predetermined rotation ratio relative to rotation of the cylinder wherein the take-down component rotates at a varying speed of the cylinder.
