Abstract
A velvet fabric knitting method is applied by performing a shearing process different from the terry-cloth construction on two different yarns in a double plated circular knitting machine and by means of the invention, light effects and episodic patterning are achieved without applying any printing process and/or using jacquard circular knitting machines. The progress is achieved by producing ring-spun, open-end, air-jet, friction yarn from different material mixtures and using them as pile yarn in the production of a velvet fabric.
Claims5
A velvet fabric knitting method comprising the steps of
- mixing a plurality of fibers comprising neps used in a pile yarn with a textile fiber comprised of natural, synthetic, regenerated fibers or a mixture of the natural, synthetic and regenerated fibers and making the plurality of fibers and the textile fiber into a plurality of slivers upon processing the plurality of fibers and the textile fibers in a carding machine;
- activating a draw frame for eliminating roughness of the plurality of slivers coming from the carding machine and splicing a plurality of sliver cotton pieces with a plurality of sliver neps and mixing the plurality of sliver neps into a main material;
- activating a roving frame for thinning a draw frame sliver cotton and a nep mixture coming from the draw frame and subjecting the draw frame sliver cotton and the nep mixture to a twisting process to obtain a plurality of cords;
- activating a ring machine for obtaining a yarn by thinning the plurality of cords coming from a main fiber and a nep mixture from a roving machine via drawing and winding the yarn onto a plurality of cops;
- knitting a greige fabric by a plurality of needles, wherein the greige fabric is turning upon upwards-downwards movement of the plurality of needles provided in a double cylinder circular knitting machine;
- knitting the pile yarn and a ground yarn by passing the pile yarn and the ground yarn through the plurality of needles in a plurality of different cylinders;
- placing the pile yarn on a fabric backcloth for shearing and then shearing thereof the pile yarn;
- activating a fixing machine for fixing a produced yarn and for stretching a pile fabric under hot air to prevent an electrostatic generation;
- and
- dyeing the pile fabric, wherein dyeing the pile fabric comprises the steps of:
- activating a centrifugal drying machine for drying the pile fabric by contacting a heated air;
- rotating a dyed fabric at least 4550 revolutions per minute in order to prevent sinking of a plurality of nep effects in the centrifugal drying machine;
- shearing the pile yarn of the pile fabric in order to turn the pile fabric into a velvet fabric by making a plurality of closed loops open-ends from a blade distance of at least 1.8 mm;
- and
- passing a dyed and sheared velvet fabric through a stenter for drying the dyed and sheared velvet fabric thereof.
