Definitions

  • the present invention relates to a method for winding an elastic yarn on a tapered bobbin in a favorable corn-like form.
  • a cone of an elastic yarn obtained has a superior unwinding character, and can provide a wound yarn body of an elastic yarn having a form of corn suitable for supplying a yarn that is used in production field for industrial materials such as paper diaper and production fields for warp knitting and warping.
  • a wound yarn body having a corn form obtainable by winding a yarn on a tapered bobbin with the yarn being traversed is widely applied in winding of an usual spun yarn and a synthetic fiber yarn such as polyester and nylon, because it has a superior unwinding character when a yarn is taken out along the direction of an end face of cone from a fixed cone.
  • winding velocity of a bobbin is different between a larger diameter side and a smaller diameter side when the yarn is wound in a cone form, a tension of winding becomes higher at a larger diameter side of the bobbin where a winding velocity is higher, and a tension of winding becomes lower at a smaller diameter side of the bobbin where a winding velocity is lower.
  • a cone of an elastic yarn for a paper diaper which has a superior wound form and unwinding character with a winding amount of not lower than 1.5 kg and a value of (winding thickness) / (winding width) of not lower than 0.4, is known (see Patent reference 1).
  • Said cone is suitable for unwinding the elastic yarn while the cone is revolved, but has a drawback, that is, a problem that the elastic yarn is caught by a lug of the cone resulting in a yarn breakage and the like, when the elastic yarn is unwound along the direction of an end face of the cone from the fixed cone.
  • a cone of an elastic yarn which has a value of (winding thickness) / (winding width) of lower than 0.4 using an elastic yarn comprising a dry spun polyurethane-urea is also known (see Patent reference 2).
  • each of these inventions relates to a parallel cheese as a fundamental form thereof, and when an elastic yarn is unwound along the direction of an end face of the cone from the fixed cone, an unwinding resistance is larger compared with that from a cone cheese, in particular, in the case of an elastic yarn of a bare polyurethane and the like, the large unwinding resistance causes problems such as yarn breakage and irregular feed tension.
  • An object of the present invention is to provide a method for producing a cone of an elastic yarn, wherein an irregular tension in winding, that is, a difference of tension for winding between a larger diameter side and a smaller diameter side in a direction of width of a tapered bobbin generated in winding an elastic yarn having a high elongation and a low stress on a tapered bobbin, has been solved, in order to obtain a cone of an elastic yarn having a superior form and an unwinding character without exhibiting unfavorable winding of a cone.
  • an irregular tension in winding that is, a difference of tension for winding between a larger diameter side and a smaller diameter side in a direction of width of a tapered bobbin generated in winding an elastic yarn having a high elongation and a low stress on a tapered bobbin
  • the inventors of the present invention intensively studied to solve the above-described problem paying attention on adjusting a position of traverse support guide, and thus accomplished the present invention.
  • the present invention provides a cone of an elastic yarn obtainable by winding an elastic yarn on a tapered bobbin with the yarn being traversed, wherein an average value of unwinding resistance of an elastic yarn from said cone of an elastic yarn is in a range of 3.2 to 3.4 g.
  • an elastic yarn is wound on a tapered bobbin with the elastic yarn being traversed to produce a cone of an elastic yarn, wherein a position of traverse support guide is moved so that a ratio (V 1 / V 2 ) of winding velocity (V 1 ) at a smaller end face of a cone of the tapered bobbin to a winding velocity (V 2 ) at a larger end face of a cone of the tapered bobbin and a ratio (L 2 / L 1 ) of a linear distance (L 2 ) between a traverse support guide and a larger end face of a cone of the tapered bobbin to a linear distance (L 1 ) between a traverse support guide and a smaller end face of a cone of the tapered bobbin become nearly equal.
  • Elastic yarn used in the present invention includes a polyurethane type of elastic yarn, a polyether type of elastic yarn, a polyester type of elastic yarn, a polyether-ester type of elastic yarn, a polyamide type of elastic yarn, a polycarbonate type of elastic yarn, a polybutylene terephthalate type of elastic yarn, and an elastic yarn obtainable by conjugating at least one of these elastic yarns and other materials.
  • the effect of the present invention is remarkably exhibited when a bare polyurethane type of elastic yarn is used, which has a high elongation and a low stress and tends to easily tangle each other due to a large coefficient of friction of yarn surface.
  • the elastic yarn may be either of a monofilament or a multifilament, but a multifilament is preferable in the present invention. Further, the elastic yarn may be adhered with a surface treatment agent such as a lubricant, or may be a bare elastic yarn. With regard to fineness thereof, an elastic yarn having such a wide range as 70 to 1,200 denier can be used.
  • Wound yarn body of an elastic yarn with a cone form may be either of a usual cone form wherein winding is performed with almost the same width from the beginning to the end of winding and a so-called pineapple form wherein a winding width becomes gradually narrower as winding progresses from the beginning to the end thereof.
  • Taper angle of a tapered bobbin used in the present invention may be, for example, in a range of 3°30' to 9°15' as usually used.
  • Cone of an elastic yarn of the present invention is produced according to the method described below, and a cone of an elastic yarn obtained has a specified value of unwinding resistance.
  • an average value of the unwinding resistance is preferably 3.2g to 3.4 g.
  • a value less than 3.2 g tends to cause unwinding by inertia due to a too small unwinding resistance, resulting in problems such as entanglement of the yarn.
  • a value over 3.4 g tends to cause yarn breakage or hinder smooth supply of the yarn.
  • a deviation of unwinding resistance represented by the equation shown below is preferably 0.16 or less.
  • a deviation over 0.16 is not preferable because a length of unwound elastic yarn is not stabilized due to a large dispersion of unwinding resistance, and for example, when an elastic yarn is used on a paper diaper manufacturing machine or a warp knitting machine, poor quality of a paper diaper or a warp knitting fabric produced may be resulted.
  • Deviation (Maximum value - Minimum value) Average value
  • Unwinding resistance of an elastic yarn of the corn is measured using a unwinding resistance measuring equipment.
  • an unwinding resistance is obtained by holding horizontally a corn of elastic yarn 11 rewound on a tapered bobbin, taking up the yarn at a velocity of 150 m/min through a plate-like yarn guide 12 equipped at the position apart by 0.46m from the rear end of the bobbin by a pair of rollers 13, 13 equipped at the position apart by 0.23m from said plate-like yarn guide 12, and measuring a tension of the elastic yarn by a tension meter 14 [model: PLS-0.2KC, made by NIDEC-SHIMPO CORPORATION] equipped at the position apart by 0.11m from said plate-like yarn guide 12.

  • the cone of an elastic yarn to be supplied for rewinding is fixed by a supporting means which is not shown in the figure, and elastic yarn 10, via guides such as a snail wire, is wound on the tapered bobbin 6 under a predetermined contacting pressure by touch roller 8 in contact with the tapered bobbin 6, while it is traversed with traversing device 9 through the traverse support guide a.
  • elastic yarn 10 is unwound from the cone of an elastic yarn to be supplied for rewinding, preferably a drive roller to positively deliver the yarn is used to reduce an influence of fluctuation of tension due to unwinding resistance.
  • Traversing velocity is calculated by an arithmetic section based on information obtained from detection sensor for number of revolution of spindle 2 and detection sensor for traversing velocity 4, so as to maintain a winding number in a range of winding width from a position of beginning of winding at the larger diameter side of the cone and a position of beginning of winding at the smaller diameter side of the cone at a predetermined value, and a signal thereof is sent from the output section.
