Definitions

  • the present invention relates to a spinning device for forming a yarn by imparting a twist into a supplied fiber bundle and in particular, to the detection of yarn defects by measuring the tension of the yarn.
  • the short staple fiber bundle of cotton or the like or the long staple fiber bundle of the wool or the like (sliver) drawn out at the draft part are formed into a fastened spun yarn by being imparted with a twist by a spinning part (air spinning nozzle, false twister) and wound on a winding package while being traversed at the winding part (traverse device, friction roller).
  • the above mentioned fastened spun yarn imparted with a twist comprises mainly a fiber bundle of which only the surface has been twisted. Due to this, if the fastening of the fiber bundle loosens while spinning the fastened spun yarn swells and becomes thicker and also becomes thinner by a reduction in the bundle of the fiber bundle thus generating stretched easily breakable weak yarn parts (defective yarn). Apart from this, defects such as slub, fat yarn, thin yarn and the like are generated on the fastened spun yarn. If this defective fastened spun yarn is wound on the winding package and used for weaving, a variety of problems such as breakage of the fastened spun yarn are caused.
  • the fastened spun yarn is passed through an electrostatic type or optical type slub catcher before being wound on the winding package and by measuring the changes in cross section (diameter changes) of the fastened spun yarn, the various yarn defects are detected.
  • the method that detects a variety of yarn defects by measuring the cross sectional changes of a fastened spun yarn by a conventional slub catcher is effective when the amount of cross sectional change is large but when the cross sectional change is minute, it is necessary to increase the sensitivity.
  • a first aspect of the present invention is a spinning device provided with a spinning part that forms spun yarn by imparting a twist in supplied fiber bundle and a winding part for winding that yarn, arranged with a tension detection part that detects yarn defects by detecting the tension of the yarn. Accordingly, by detecting the yarn tension that changes in response to the defective state of the yarn, defects of the yarn and in particular weak yarn part may be detected.
  • a thickness detection part that detects the yarn defects by measuring the thickness of the yarn is arranged. Accordingly, by measuring the thickness of the yarn, a thin yarn part, a thin yarn part and slub may be detected and by measuring the tension, a weak yarn part may be detected.
  • the winding part winds the yarn by traversing and the tension detection part is arranged on that winding part immediately before the traversing of the yarn and detects abnormal values of the winding tension. Accordingly, yarn defects may be detected as well as stitching and straight winding generated on the package wound by traversing the yarn.
  • the spinning part is a fastened spun yarn spinning part that spins fastened spun yarn. Accordingly, when a weak yarn part is generated in the fastened spun yarn, as the restriction force of the wrapped fibers that restrict the core fiber bundle of the yarn decreases and the tension of the yarn decreases, a weak yarn part may be detected with great sensitivity due to tension changes.
  • a second aspect of the present invention is a spinning method that forms spun yarn by imparting a twist in supplied fiber bundle and detects yarn defects by detecting the tension of the yarn. Accordingly, by detecting the tension of the yarn that changes in response to the defective state of the yarn, defects of the yarn and in particular a weak yarn part may be detected.
  • the spinning is stopped. Accordingly, as the spinning is automatically stopped when a defect is detected, spinning may be quickly restarted after removing the yarn defect.
  • the aforementioned yarn is a fastened spun yarn. Accordingly, when a weak yarn part is generated in the fastened spun yarn, as the restriction force of the wrapped fibers that restrict the core fiber bundle of the yarn decreases and the tension of the yarn decreases, a weak yarn part may be detected with great sensitivity due to tension changes.
