Definitions

  • the present invention relates to a spun yarn drawing apparatus configured to draw yarns spun out from a spinning apparatus.
  • Patent Literature 1 Japanese Unexamined Patent Publication No. 2014-77221 discloses a spun yarn drawing apparatus configured to draw yarns such as polyethylene terephthalate (PET) yarns spun out from a spinning apparatus.
  • the spun yarn drawing apparatus includes: at least one first roller; and a plurality of second rollers which are provided downstream of the first roller in a yarn running direction. Each second roller has a yarn feeding speed higher than that of the first roller, and functions as a heating roller.
  • the yarns spun out from the spinning apparatus are drawn between the first roller and the second roller, and the thus drawn yarns are heat-set by the second rollers. Physical properties of the yarns are controlled by changing conditions in such a drawing process and a heat-set process.
  • the boiling water shrinkage (BWS) of the yarns is reduced by setting the yarn feeding speeds of the second rollers so that between every two second rollers adjacent to each other in a yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is lower than that of the second roller located upstream in the yarn running direction, to perform relaxation heat treatment in which the yarns are heat-set in a relaxed state.
  • the Young's modulus ("modulus") of the yarns is increased by setting the yarn feeding speeds of the second rollers so that between every two second rollers adjacent to each other in the yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is higher than that of the second roller located upstream in the yarn running direction, to perform heat treatment under tension in which the yarns are heat-set in a stretched state.
  • an object of the present invention is to provide a spun yarn drawing apparatus which enables a wider range of control of physical properties of yarns.
  • the speed controller controls the yarn feeding speeds of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is lower than the yarn feeding speed of the second roller located upstream in the yarn running direction; and the temperature controller controls the temperatures of the three or more second rollers so that the temperature of the second roller located most downstream in the yarn running direction is higher than or equal to the temperature of each of the remaining second rollers.
  • the yarn is drawn between the first roller and the second roller, and the yarn feeding speeds of the three or more second rollers are controlled so that between every two second rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is lower than the yarn feeding speed of the second roller located upstream in the yarn running direction.
  • relaxation heat treatment in which the yarn is heat-set in a relaxed state.
  • the temperature of the second roller located most downstream in the yarn running direction is higher than or equal to the temperatures of the remaining second rollers.
  • the yarn is strongly heated in the situation where the relaxed state of the yarn has been enhanced and its molecules have a high mobility.
  • the temperatures of the second rollers in addition to the yarn feeding speeds of the second rollers as described above, molecular chains are effectively relaxed, and thereby effects of the relaxation heat treatment are enhanced than before. This enables a wider range of control of physical properties of the yarn.
  • the temperature controller controls the temperatures of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the temperature of the second roller located downstream in the yarn running direction is higher than or equal to the temperature of the second roller located upstream in the yarn running direction.
  • the temperature controller controls the temperatures of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the temperature of the second roller located upstream in the yarn running direction is lower than the temperature of the second roller located downstream in the yarn running direction.
  • each of the temperatures of the remaining second rollers may be identical to the temperature of the second roller located most downstream in the yarn running direction.
  • a heating device configured to heat the yarn is provided in at least one of sections each of which is between two second rollers adjacent to each other in the yarn running direction out of the three or more second rollers.
  • the thus provided heating device improves the performance of the heat treatment, and enables the yarn to be heat-set well.
  • the heating device is disposed between the two second rollers which are located most downstream in the yarn running direction.
  • the yarn which has been relaxed is further heated by the heating device.
  • the effects of the relaxation heat treatment are further enhanced. This enables a still wider range of control of the physical properties of the yarn.
  • the spun yarn drawing apparatus further includes a thermal insulation box which houses at least one of the three or more second rollers, and that the heating device is disposed inside the thermal insulation box.
  • the heating device is disposed inside the thermal insulation box, the loss of heat from the heating device is reduced, which improves the effects of the heat treatment by the heating device.
  • the spun yarn drawing apparatus may further include a thermal insulation box which houses at least one of the three or more second rollers, and the spun yarn drawing apparatus may be arranged such that the heating device is disposed outside the thermal insulation box.
  • the above arrangement in which the heating device is disposed outside the thermal insulation box, allows the size of the heating device to be increased irrespective of the size of the thermal insulation box. With this, the heating performance of the heating device is easily improved.
  • the speed controller controls the yarn feeding speeds of the three or more second rollers so that tension of the yarn traveling between every two second rollers which are adjacent to each other in the yarn running direction is not less than 0.05 g/de.
  • tension of the yarn is less than 0.05 g/de, yarn swaying may occur, which possibly causes undesirable winding of the yarn around the rollers and/or yarn breakage. These problems are avoided or reduced by controlling the tension of the yarn to be not less than 0.05 g/de.
  • the speed controller controls the yarn feeding speeds of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is higher than the yarn feeding speed of the second roller located upstream in the yarn running direction; and the temperature controller controls the temperatures of the one or more second rollers functioning as the heating rollers out of the three or more second rollers so that the temperature of the second roller located most upstream in the yarn running direction is higher than or equal to the temperature of each of the remaining second rollers.
  • the yarn is drawn between the first roller and the second roller, and the yarn feeding speeds of the three or more second rollers are controlled so that between every two second rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the second roller located downstream in the yarn running direction is higher than the yarn feeding speed of the second roller located upstream in the yarn running direction.
  • performed is heat treatment under tension in which the yarn is heat-set in a stretched state.
  • the stretched state of the yarn is enhanced.
  • the temperature of the second roller located most upstream in the yarn running direction is higher than or equal to the temperatures of each of the remaining second rollers.
  • the yarn is strongly heated in the situation where the stretched state of the yarn is at a lower level and its molecules have a high mobility. Further, since the increase in the temperature of the yarn by the second rollers located downstream in the yarn running direction is suppressed, relaxation of stretched molecular chains is prevented. By controlling the temperatures of the second rollers in addition to the yarn feeding speeds of the second rollers as described above, crystallization is effectively facilitated and the relaxation of the stretched molecular chains is prevented. Thus, effects of the heat treatment under tension are enhanced than before. This enables a wider range of control of the physical properties of the yarn.
  • the temperature controller controls the temperatures of the one or more second rollers functioning as the heating rollers out of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the temperature of the second roller located upstream in the yarn running direction is higher than or equal to the temperature of the second roller located downstream in the yarn running direction.
  • the temperature controller controls the temperatures of the one or more second rollers out of the three or more second rollers so that between every two second rollers which are adjacent to each other in the yarn running direction, the temperature of the second roller located downstream in the yarn running direction is lower than the temperature of the second roller located upstream in the yarn running direction.
  • each of the temperatures of the remaining second rollers may be identical to the temperature of the second roller located most upstream in the yarn running direction.
  • the crystallization cannot efficiently proceed even though the yarn is strongly heated, and therefore the effect brought by the heating is smaller for the yarn traveling downstream in the yarn running direction. Further, because the increase in the temperature of the yarn by the second rollers located downstream in the yarn running direction is suppressed, the relaxation of the stretched molecular chains is prevented.
  • the speed controller controls the yarn feeding speeds of the three or more second rollers so that tension of the yarn traveling between every two second rollers which are adjacent to each other in the yarn running direction does not exceed 1 g/de.
  • the speed controller controls the yarn feeding speeds of the three or more second rollers so that a difference in the yarn feeding speed between every two second rollers which are adjacent to each other in the yarn running direction does not exceed 30 m/min.
  • controlling the temperatures in addition to the yarn feeding speeds of the three or more second rollers enables a wider range of control of the physical properties of the yarn.

With this, preliminary heating is performed to increase the temperature of the yarns Y before drawn to the glass transition temperature or higher. Note that the glass transition temperature differs depending on the type of polymers, and therefore the temperatures T1 and T2 of the first godet rollers 21a and 21b are set depending on the material of the yarns Y.

With this, the yarns Y are drawn between the first godet roller 21b and the second godet roller 22a.
  • the speed controller 31 controls the yarn feeding speeds V3, V4, and V5 of the second godet rollers 22a, 22b, and 22c so that each of the differences in the yarn feeding speed between the rollers 22a and 22b and between the rollers 22b and 22c does not exceed 30 m/min.
  • the tension of the yarns Y is properly kept, to prevent undesirable winding of the yarns Y around a roller and/or yarn breakage.

  • the yarns Y spun out from the spinning apparatus 4 are preliminarily heated by the first godet rollers 21a and 21b to the glass transition temperature or higher, then the yarns Y are drawn between the first godet roller 21b and the second godet roller 22a, and heat-set by the second godet rollers 22a, 22b, and 22c.
  • the higher the draw ratio in the process of drawing the yarns Y is, the higher the strength and the Young's modulus are, but the lower the elongation is.
  • the lower the draw ratio is, the lower the strength and the Young's modulus are, but the higher the elongation is. That is, physical properties of the yarns Y are adjusted by adjusting the draw ratio of the yarns Y.
  • the temperatures are increased too much, for example, to 200 degrees centigrade or higher, deterioration of the yarns Y (decrease in strength and elongation) and/or yarn breakage occur more commonly.
  • the Young's modulus is increased by increasing the draw ratio in the process of drawing of the yarns Y. But if so, the elongation decreases too much, which causes yarn breakage and/or fluff more commonly.
  • the increase of the Young' s modulus in the spun yarn drawing apparatus 2, the yarn feeding speeds and the temperatures of the three second godet rollers 22a, 22b, and 22c are controlled independently from one another. This enables production of the super low shrinkage yarns and the high modulus yarns. The following will describe its principle.
  • the yarn feeding speeds V3, V4, and V5 of the second godet rollers 22a, 22b, and 22c are controlled by the speed controller 31 so that between every two second godet rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the roller located downstream in the yarn running direction is lower than that of the roller located upstream in the yarn running direction, i.e., so that V3 > V4 > V5 is satisfied.
  • the relaxation heat treatment in which the yarns Y are heat-set in the relaxed state is performed. With this relaxation heat treatment, the degree of molecular orientation in amorphous regions decreases, which decreases the boiling water shrinkage of the yarns Y.
  • the temperatures T3, T4, and T5 of the second godet rollers 22a, 22b, and 22c are controlled by the temperature controller 32 so that the temperature T5 of the second godet roller 22c which is located most downstream in the yarn running direction is higher than or equal to each of the temperatures T3 and T4 of the remaining second godet rollers 22a and 22b, i.e., so that T3 ⁇ T5 and T4 ⁇ T5 are satisfied.
  • the relaxed state of the yarns Y is enhanced.
  • the temperature T5 of the second godet roller 22c which is located most downstream in the yarn running direction is higher than or equal to each of the temperatures T3 and T4 of the remaining second godet rollers 22a and 22b. Therefore, the yarns Y are strongly heated in the situation where the relaxed state of the yarns Y has been enhanced and their molecules have a high mobility.
  • the temperature controller 32 controls the temperatures T3, T4, and T5 of the second godet rollers 22a, 22b, and 22c so that, between every two second godet rollers which are adjacent to each other in the yarn running direction (between the second godet rollers 22a and 22b and between the second godet rollers 22b and 22c), the temperature of the second godet roller which is located downstream in the yarn running direction is higher than or equal to the temperature of the second godet roller which is located upstream in the yarn running direction, i.e., so that T3 ⁇ T4 ⁇ T5 is satisfied.
  • the more downstream in the yarn running direction the yarns Y travel that is, the more the relaxed state of the yarns Y is enhanced, the more strongly the yarns Y are heated. This surely and effectively enhances the effects of the relaxation heat treatment.
  • the temperature T5 of the second godet roller 22c which is located most downstream in the yarn running direction is higher than or equal to each of the temperatures T3 and T4 of the remaining second godet rollers 22a and 22b. That is, each of the temperatures T3 and T4 of the remaining second godet rollers 22a and 22b may be identical to the temperature T5 of the second godet roller 22c which is located most downstream in the yarn running direction.
  • the molecular chains cannot be efficiently relaxed even though the yarns Y are strongly heated, and therefore the effect brought by the heating is smaller for the yarns Y traveling upstream in the yarn running direction.
  • the temperature of the roller which is located upstream in the yarn running direction is lower than that of the roller located downstream in the yarn running direction, i.e., so that T3 ⁇ T4 ⁇ T5 is satisfied, useless heating is reduced, and the physical properties of the yarns Y are efficiently controlled.
  • the heating device 25 configured to heat yarns Y is provided in at least one of sections each of which is between two second godet rollers adjacent to each other in the yarn running direction (in at least one of sections between the second godet rollers 22a and 22b and between the second rollers 22b and 22c). This improves the performance of the heat treatment, and enables the yarns Y to be heat-set well.
  • the heating device 25 is provided between the two second godet rollers 22b and 22c which are located most downstream in the yarn running direction.
  • the yarns Y which have been relaxed are further heated by the heating device 25.
  • the effects of the relaxation heat treatment are further enhanced. This enables a still wider range of control of the physical properties of the yarns Y.
  • the heating device 25 is disposed inside the thermal insulation box 24, the loss of heat from the heating device 25 is reduced, which improves the effects of the heat treatment by the heating device 25.
  • the speed controller 31 controls the yarn feeding speeds V3, V4,and V5 of the second godet rollers 22a, 22b, and 22c so that the tension of the yarns Y traveling between every two second godet rollers which are adjacent to each other in the yarn running direction is not less than 0.05 g/de. If the tension of the yarn Y is less than 0.05 g/de, yarn swaying may occur, which possibly causes undesirable winding of the yarns Y around the rollers and/or yarn breakage. These problems are avoided or reduced by controlling the tension of the yarns to be not less than 0.05 g/de.
  • the yarn feeding speeds V3 , V4 , and V5 of the second godet rollers 22a, 22b, and 22c are controlled by the speed controller 31 so that between every two second godet rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the roller located downstream in the yarn running direction is higher than that of the roller located upstream in the yarn running direction, i.e., so that V3 ⁇ V4 ⁇ V5 is satisfied.
  • the heat treatment under tension in which the yarns Y are heat-set in the stretched state is performed. With this heat treatment under tension, the degree of molecular orientation in the amorphous regions increases, which increases the Young's modulus of the yarns Y.
  • the temperatures T3, T4, and T5 of the second godet rollers 22a, 22b, and 22c are controlled by the temperature controller 32 so that the temperature T3 of the second godet roller 22a which is located most upstream in the yarn running direction is higher than or equal to each of the temperatures T4 and T5 of the remaining second godet rollers 22b and 22c, i.e., so that T3 ⁇ T4 and T3 ⁇ T5 are satisfied.
  • the stretched state of the yarns Y is enhanced.
  • the temperature T3 of the second godet roller 22a which is located most upstream in the yarn running direction is higher than or equal to each of the temperatures T4 and T5 of the remaining second godet rollers 22b and 22c. Therefore, the yarns Y are strongly heated in the situation where the stretched state of the yarns Y is at a lower level and their molecules have a higher mobility. Further, since the increase in the temperature of the yarns Y by the second godet rollers 22b and 22c located downstream in the yarn running direction is suppressed, relaxation of stretched molecular chains is prevented.
  • the temperature controller 32 controls the temperatures T3, T4, and T5 of the second godet rollers 22a, 22b, and 22c so that between every two second godet rollers which are adjacent to each other in the yarn running direction (between the second godet rollers 22a and 22b and between the second godet rollers 22b and 22c), the temperature of the second godet roller which is located upstream in the yarn running direction is higher than or equal to the temperature of the second godet roller which is located downstream in the yarn running direction, that is, so that T3 ⁇ T4 ⁇ T5 is satisfied.
  • the more upstream in the yarn running direction the yarns Y travel the more strongly the yarns Y are heated.
  • the yarns Y are strongly heated in the situation where crystallization has not yet proceeded and thus the molecules have a high mobility. This surely and efficiently enhances the effects of the heat treatment under tension.
  • the temperature T3 of the second godet roller 22a which is located most upstream in the yarn running direction is higher than or equal to each of the temperatures T4 and T5 of the remaining second godet rollers 22b and 22c. That is, each of the temperatures T4 and T5 of the remaining second godet rollers 22b and 22c may be identical to the temperature T3 of the second godet roller 22a which is located most upstream in the yarn running direction.
  • the crystallization cannot efficiently proceed even though the yarns Y are strongly heated, and therefore the effect brought by the heating is smaller for the yarns Y traveling downstream in the yarn running direction.
  • the second godet rollers 22b and 22c which are located downstream in the yarn running direction is suppressed, the relaxation of the stretched molecular chains is prevented.
  • T3, T4, and T5 of the second godet rollers 22a, 22b, and 22c so that between every two second godet rollers which are adjacent to each other in the yarn running direction, the temperature of the roller which is located downstream in the yarn running direction is lower than that of the roller located upstream in the yarn running direction, i.e., so that T3 > T4 >T5 is satisfied, useless heating is reduced, and the relaxation of the stretched molecular chains is prevented.
  • the physical properties of the yarns Y are efficiently controlled.
  • the speed controller 31 controls the yarn feeding speeds V3, V4, and V5 of the second godet rollers 22a, 22b, and 22c so that the tension of the yarns Y traveling between every two second godet rollers which are adjacent to each other in the yarn running direction does not exceed 1 g/de. If the tension of the yarn Y exceeds 1 g/de, yarn breakage and/or fluff may occur. These problems are avoided or reduced by controlling the tension of the yarns Y so that the tension does not to exceed 1 g/de.
  • the heating device 25 it is preferable to dispose the heating device 25 as upstream as possible in the yarn running direction. For example, it is optimum to locate the heating device 25 between the two second godet rollers 22a and 22b which are located most upstream in the yarn running direction.

  • the first godet rollers 21a and 21b on which the yarns Y before drawn travel are heating rollers.
  • non-heating rollers each of which does not include a heater may be used as the first godet rollers 21a and 21b, or the first godet rollers 21a and 21b respectively including the heaters may be used in a non-heating state established by shutting down the power supply to the heaters.
  • rollers 22a, 22b, and 22c are the three second godet rollers 22a, 22b, and 22c as rollers configured to heat-set the drawn yarns Y; however, the number of such rollers is not limited to three, as long as three or more such rollers are provided.
