技术领域 technical field
本发明涉及一种纺纱装置,将构成从牵伸装置送出的纱线的纤维,通过由产生回转气流的喷嘴部和非旋转中空导向轴部件构成的纺纱部件进行加捻,来制造纱线(纺绩系)。The present invention relates to a spinning device for twisting the fibers constituting the yarn sent out from a drafting device by a spinning member composed of a nozzle portion generating a swirling air flow and a non-rotating hollow guide shaft member to produce yarn (Department of Textiles).
背景技术 Background technique
已知的一种纺纱装置,由产生回转气流的喷嘴部件和具有纱插通孔的非旋转导向轴部件构成、将喷嘴部件产生的回转气流作用于中空导向轴部件的前端部,进行纺纱。在这种纺纱装置中,在中空导向轴部件的前端部产生反转纤维,此反转纤维由于喷嘴部件引起的旋转气流在中空导向轴部件的前端部旋转。即,中空导向轴部件前端部成为反转纤维的接触区域。并且,旋转的反转纤维被引入中空导向轴部件的纱插通孔的纤维束卷绕,制造成实捻状的纱线。A known spinning device is composed of a nozzle member generating a swirling airflow and a non-rotating guide shaft member having a yarn insertion hole. The swirling airflow generated by the nozzle member is applied to the front end of the hollow guide shaft member to perform spinning. . In such a spinning device, reversed fibers are generated at the front end of the hollow guide shaft member, and the reversed fibers are rotated at the front end of the hollow guide shaft member by the swirling airflow caused by the nozzle member. That is, the front end portion of the hollow guide shaft member becomes a contact area of the inverted fibers. Then, the rotated reversed fiber is wound by the fiber bundle introduced into the yarn insertion hole of the hollow guide shaft member to produce a true twisted yarn.
但是,由于中空导向轴部件前端部的外周面形状及中空导向轴部件的纱插通孔形状,在与中空导向轴部件的轴线垂直的断面形成为圆形(正圆),反转纤维在中空导向轴部件的圆周方向以大致一定的速度回转。这样,当在中空导向轴部件的前端部上反转纤维在圆周方向上以大致一定的速度回转时,由于反转纤维没有绞乱,纺出的纱线上产生的绒毛数少,会产生表面感触硬的纱线。However, due to the shape of the outer peripheral surface of the front end of the hollow guide shaft member and the shape of the yarn insertion hole of the hollow guide shaft member, the cross-section perpendicular to the axis of the hollow guide shaft member is formed in a circular (perfect circle), and the inverted fiber is hollowed out. The circumferential direction of the guide shaft member rotates at a substantially constant speed. In this way, when the reversed fibers are rotated at a substantially constant speed in the circumferential direction on the front end of the hollow guide shaft member, since the reversed fibers are not twisted, the number of fluffs generated on the spun yarn is small, and surface roughness will occur. Feel hard yarn.
通过降低从喷嘴部件喷射的压缩空气的空气压力,反转纤维的后端部受到的旋转气流的影响弱,反转纤维的后端部易从中空导向轴部件前端部的外周面上离开,纺出的纱线的绒毛应该会增多。但是,由于如喷嘴部件的喷射空气压低,产生的纱线的强度下降,会产生断纱率增加,纺纱性降低的问题。By reducing the air pressure of the compressed air injected from the nozzle member, the rear end of the reversed fiber is less affected by the swirling air flow, and the rear end of the reversed fiber is easily separated from the outer peripheral surface of the front end of the hollow guide shaft member, spinning The resulting yarn should have more fluff. However, as the pressure of the jetting air from the nozzle member is lowered, the strength of the yarn is lowered, the yarn breakage rate increases, and the spinnability is lowered.

本发明提供一种纺纱用中空导向轴部件,具有供由纤维束生成的纱线通过的纱插通孔,通过在前端部的外方产生旋转气流,使反转纤维在该前端部边旋转边进行纺纱,其特征为,前端部的外周所形成的形状为,在与轴线垂直的断面形状为纵长形状或椭圆形状。本发明为了实现上述的目的,第1是,在由发生旋转气流的喷嘴部件和具有纱插通孔的非回转的中空导向轴部件构成,通过喷嘴部件将旋转气流使用于中空导向轴部件的前端部上并同时进行纺纱的纺纱装置中,中空导向轴部件的前端部的纱插通孔的断面形状形成非圆形状。由此,可以使反转纤维的旋转速度在圆周方向上发生变化,从而,纺出的纱线的绒毛的产生多,所生成的纱线的强度不会低下,能够制造绒毛多并柔软的纱线。此外,由于不需变更喷嘴部件的喷嘴压(喷射压),能够维持纺纱上最适宜的流量,防止产生相对于纱支数等的物性值的偏差。The present invention provides a hollow guide shaft member for spinning, which has a yarn insertion hole through which a yarn produced from a fiber bundle passes, and generates a swirling airflow outside the front end so that reversed fibers are rotated at the front end. The edge spinning is characterized in that the outer periphery of the tip portion has a shape that is vertically elongated or elliptical in a cross-sectional shape perpendicular to the axis. In order to achieve the above objects, the present invention is firstly composed of a nozzle member generating a swirling airflow and a non-rotating hollow guide shaft member having a yarn insertion hole, and the swirling airflow is applied to the front end of the hollow guide shaft member through the nozzle member. In the spinning device that spins yarn simultaneously on the upper part, the cross-sectional shape of the yarn insertion hole at the front end of the hollow guide shaft member is non-circular. In this way, the rotational speed of the reversed fiber can be changed in the circumferential direction, so that the spun yarn has a lot of fuzz, the strength of the yarn produced will not be lowered, and a soft yarn with a lot of fuzz can be produced. Wire. In addition, since it is not necessary to change the nozzle pressure (jet pressure) of the nozzle member, it is possible to maintain an optimum flow rate for spinning and prevent variations in physical property values with respect to yarn count and the like.
第2是,中空导向轴部件的前端部的纱插通孔的断面形状为纵长或椭圆孔。由此,可以使反转纤维的旋转速度在圆周方向上平滑地变化,防止发生断纱等。The second is that the cross-sectional shape of the yarn insertion hole at the front end portion of the hollow guide shaft member is a vertically long or elliptical hole. Thereby, the rotational speed of the reversed fiber can be changed smoothly in the circumferential direction, and yarn breakage and the like can be prevented.
第3是,形成非圆形状的纱插通孔的长度从位于中空导向轴部件的前端面上的纱插通孔入口开始,最长为构成纤维束的纤维的平均长度。即,在纱插通孔中,从位于中空导向轴部件的前端面的纱插通孔入口开始的特定长度为非圆形状,其下游侧连接有圆形(正圆)部分。并且,纱插通孔非圆形状部分的长度在构成纤维束的纤维的平均纤维长度以下。由此,可仅使与反转纤维的旋转有关的部分为非圆形状,而与反转纤维的旋转无关部分的断面为圆形,能够维持中空导向轴部件的纱插通孔内平滑的空气流,能够防止生成的纱线质量下降。The third is that the length of the yarn insertion hole formed in a non-circular shape starts from the entrance of the yarn insertion hole located on the front end surface of the hollow guide shaft member to the longest average length of the fibers constituting the fiber bundle. That is, in the yarn insertion hole, a certain length from the entrance of the yarn insertion hole located on the front end surface of the hollow guide shaft member is non-circular, and a circular (perfect circle) portion is connected to the downstream side. In addition, the length of the non-circular portion of the yarn insertion hole is equal to or less than the average fiber length of the fibers constituting the fiber bundle. Thereby, only the part related to the rotation of the reversed fiber can be made non-circular, and the cross section of the part not related to the rotation of the reversed fiber can be made circular, and the smooth air in the yarn insertion hole of the hollow guide shaft member can be maintained. flow, which prevents deterioration of the quality of the produced yarn.
第4是,在由发生旋转气流的喷嘴部件和具有纱插通孔的非回转的中空导向轴部件构成,通过由喷嘴部件产生的旋转气流,在中空导向轴部件的前端部上反转纤维旋转并同时进行纺纱的纺纱装置中,在作为反转纤维的接触领域的中空导向轴部件的前端部的外周面上,设置有使反转纤维的旋转速度在圆周方向部分变化的抑制部。由此,可以使反转纤维的旋转速度在圆周方向上发生变化,从而,在生成的纱线的强度不会降低,纺出的纱线产生的绒毛多的同时,由于抑制了纱线的卷绕纤维的张紧,能够制造绒毛多并柔软的纱线。再者,这种纱线织成的布制品的柔软感增大,同时由于纱自身的回转力矩减小,能够提高后续工序中的纱的解舒性,还会提高染色性。The fourth is to reverse the rotation of the fiber at the front end of the hollow guide shaft member by the swirling air flow generated by the nozzle member and the non-rotating hollow guide shaft member having a yarn insertion hole. In a spinning device that simultaneously spins, a suppressing portion that partially changes the rotational speed of the reversed fibers in the circumferential direction is provided on the outer peripheral surface of the front end portion of the hollow guide shaft member that is the contact area of the reversed fibers. Thus, the rotation speed of the reversed fiber can be changed in the circumferential direction, so that the strength of the generated yarn will not be reduced, and the spun yarn will produce more fluff, and the twisting of the yarn can be suppressed. The tension around the fibers enables the production of fuzzy and soft yarns. Furthermore, the soft feeling of the cloth products woven with such yarns is increased, and at the same time, since the rotational moment of the yarn itself is reduced, the unwinding properties of the yarns in the subsequent process can be improved, and the dyeability can also be improved.
第5是,在中空导向轴部件的前端部的外周面上,形成作为抑制部的平坦面。由此,能够在圆周方向上有效地改变反转纤维的旋转速度。The fifth is to form a flat surface as a suppressing portion on the outer peripheral surface of the front end portion of the hollow guide shaft member. Thereby, the rotational speed of the reversed fiber can be effectively changed in the circumferential direction.
第6是,作为抑制部的平坦面在圆圆周方向上大致等间隔地形成。由此,可更有效地改变反转纤维的旋转速度。Sixthly, the flat surfaces serving as the restraining portions are formed at substantially equal intervals in the circumferential direction. Thereby, the rotational speed of the inverted fiber can be changed more effectively.
第7是,在中空导向轴部件的前端部的外周面上,形成作为抑制部的凸部或槽部。由此,能够在圆周方向上有效地改变反转纤维的旋转速度。The seventh is to form a convex portion or a groove portion as a suppressing portion on the outer peripheral surface of the front end portion of the hollow guide shaft member. Thereby, the rotational speed of the reversed fiber can be effectively changed in the circumferential direction.
第8是,在中空导向轴部件的前端部的外周面上,形成作为抑制部的十字形槽部。由此,在反转纤维进入槽部的场合,抑制了在圆周方向旋转的反转纤维的旋转力,能够在圆周方向上改变反转纤维的旋转速度。Eighth, a cross-shaped groove portion is formed as a restraining portion on the outer peripheral surface of the front end portion of the hollow guide shaft member. Accordingly, when the reversed fiber enters the groove, the rotational force of the reversed fiber rotating in the circumferential direction is suppressed, and the rotational speed of the reversed fiber can be changed in the circumferential direction.
第9是,在由发生旋转气流的喷嘴部件和具有纱插通孔的非回转的中空导向轴部件构成、通过由喷嘴部件产生的旋转气流,在中空导向轴部件的前端部上反转纤维旋转并同时进行纺纱的纺纱装置中,中空导向部件前端部中的反转纤维的接触领域的外周形状以相对于中空导向轴部件的轴线垂直的断面形状为非圆形的状态形成。由此,可以使反转纤维的旋转速度在圆周方向上发生变化,从而,所生成的纱线的强度不会降低,纺出的纱线的绒毛的产生多的同时,由于抑制了纱线的卷绕纤维的张紧,能够制造绒毛多并柔软的纱线。再者,这种纱线织成的布制品的柔软感增大,同时由于纱自身的回转力矩减小,能够提高后续工序中的纱的解舒性,还会提高染色性。The ninth is to reverse the fiber rotation at the front end of the hollow guide shaft member by the swirling air flow generated by the nozzle member and the non-rotating hollow guide shaft member having a yarn insertion hole. In the spinning device that simultaneously spins, the outer peripheral shape of the contact region of the inverted fibers at the front end of the hollow guide member is formed in a non-circular cross-sectional shape perpendicular to the axis of the hollow guide shaft member. Thus, the rotation speed of the reversed fiber can be changed in the circumferential direction, so that the strength of the generated yarn will not be reduced, and the spun yarn will have more fluff, and the yarn will be suppressed. Tensioning of the wound fibers enables the production of fuzzy and soft yarns. Furthermore, the soft feeling of the cloth products woven with such yarns is increased, and at the same time, since the rotational moment of the yarn itself is reduced, the unwinding properties of the yarns in the subsequent process can be improved, and the dyeability can also be improved.
第10是,在通过作用于非回转的中空导向轴部件的前端部上的旋转气流,在中空导向轴部件的前端部使反转纤维回转并同时进行纺纱的纺纱方法中,中空导向轴部件前端部上的反转纤维的旋转速度在圆周方向上积极地变化。由此,所生成的纱线的强度不会降低,纺出的纱线的绒毛的产生多的同时,由于抑制了纱线的卷绕纤维的张紧,能够制造绒毛多并柔软的纱线。再者,这种纱线织成的布制品的柔软感增大,同时由于纱自身的回转力矩减小,能够提高后续工序中的纱的解舒性,还会提高染色性。The tenth is that in the spinning method in which the reversed fiber is rotated at the front end of the hollow guide shaft member by the whirling air flow acting on the front end of the non-rotating hollow guide shaft member and spinning is performed simultaneously, the hollow guide shaft The rotational speed of the inverted fibers on the component front end varies positively in the circumferential direction. Thereby, the strength of the produced yarn is not lowered, and the spun yarn has a lot of fuzz, and since the tension of the yarn winding fibers is suppressed, a soft yarn with a lot of fuzz can be produced. Furthermore, the soft feeling of the cloth products woven with such yarns is increased, and at the same time, since the rotational moment of the yarn itself is reduced, the unwinding properties of the yarns in the subsequent process can be improved, and the dyeability can also be improved.
第11是,中空导向轴部件前端部上的反转纤维的旋转在圆周方向上部分地抑制,使旋转速度变化。由此,能够在圆周方向上有效地改变反转纤维的旋转速度。Eleventh, the rotation of the inverted fiber at the front end of the hollow guide shaft member is partially suppressed in the circumferential direction, and the rotation speed is changed. Thereby, the rotational speed of the reversed fiber can be effectively changed in the circumferential direction.

以下利用图1—图11对与本发明特征部分相关的结构进行说明。The structure related to the characteristic part of the present invention will be described below using FIGS. 1 to 11 .
首先,利用图1—图6对实现本发明目的的特征的结构进行说明。本发明人研究的结果为,通过从喷头1的空气喷射孔1a喷射的喷射空气而在第1中空导向轴7的前端7a(反转纤维v1的接触领域)周围形成的旋转气流,反转纤维v1在第1中空导向轴7的前端部7a的圆周方向上以大致一定的速度旋转时,反转纤维v1不会紊乱,纺出的纱线产生的绒毛较少,而在第1中空导向轴7的前端部7a中,抑制圆周方向旋转的反转纤维v1的旋转力,使反转纤维v1的速度在圆周方向上变化时,反转纤维v1的纤维后端部v1”容易从第1中空导向轴7的前端部7a的外周面离开,纺出的纱线的绒毛的发生较多。即,反转纤维v1的旋转速度在圆周方向上积极地变化时,绒毛数增加,可以制造出柔软的纱线。First, the characteristic configuration for achieving the object of the present invention will be described using FIGS. 1 to 6 . As a result of the research of the present inventors, the swirling airflow formed around the
在第1中空导向轴7的前端部7a中,为了使在圆周方向上旋转的反转纤维v1的旋转速度在圆周方向变化,在图1及图2所示的实施例中,使第1中空导向轴7上的纱插通孔7b从前端部7a侧看去形成纵长的孔7b1的形状。在纱插通孔7b的全长,即第1中空导向轴7的全长上,纱插通孔7b可形成纵长孔7b1,但如果从纱插通孔7b的前端部7a的前端面7a’开始,形成最长仅为构成纱条V的纤维v的平均纤维的长度的纵长孔7b1,如上所述,可抑制在圆周方向上旋转的反转纤维v1的旋转力,使反转纤维v1的旋转速度充分地变化。In the
如上所述,由于在形成于第1中空导向轴7上的纱插通孔7b的前端部7a附近形成纵长孔7b1,在圆周方向上旋转的反转纤维v1在纵长孔7b1的长边侧7b1’中阻抗较少,旋转速度快,此外,由于在从长边侧7b1’向短边侧7b1”移动阶段及从短边侧7b1”向长边侧7b1’移动阶段阻抗加大,旋转速度变慢。这样,通过在纱插通孔7b的前端部7a附近形成纵长孔,抑制了在圆周方向上旋转的反转纤维v1旋转力,能够使反转纤维v1的旋转速度变化,从而,纺出的纱线的绒毛的生产较多,不会降低生成的纱线的强度,可以制造出绒毛多,柔软的纱线。作为能够不降低纤维纱的强度、增加绒毛的原因,可以考虑是由于卷绕在周围的纤维的卷绕力不一定产生纱强力,能够使卷绕而不产生强力的纤维成为绒毛。。As described above, since the longitudinally long hole 7b1 is formed near the
在图3及图4所示的实施例中,形成于第1中空导向轴7上的纱插通孔7b从前端部7a侧所见到的形状为椭圆孔7b2。在圆周方向上旋转的反转纤维v1在通过椭圆孔7b2的长径的两端部7b2’时,由于阻抗增大,旋转速度变慢。与上述相同,在纱插通孔7b的全长,即第1中空导向轴7的全长上,纱插通孔7b可形成椭圆孔7b2,但如果从纱插通孔7b的前端部7a的前端面7a’开始,形成最长仅为构成纱条V的纤维v的平均纤维长的长度的椭圆孔7b2,则如上所述,可使在圆周方向上旋转的反转纤维v1的旋转速度充分地变化。In the embodiment shown in FIG. 3 and FIG. 4, the shape of the
如上所述,形成于第1中空导向轴7上的纱插通孔从7b的前端部7a侧所见的形状为具有垂直相交的长径与短径的纵长孔7b1或椭圆孔7b2的场合,短径的长度决定纱线的张紧状况(纱强力)。从而,即使是纱插通孔7b的截面积加大,通过将短径的长度抑制在与截面为圆形时的直径相同程度,可以不降低纱强度,生成柔软的纱线。As described above, the shape of the yarn insertion hole formed on the first
图5及图6所示的实施例为大致形成为方形孔7b3的情况,在圆周方向上旋转的反转纤维v1在通过大致方形孔7b3的角部7b3’时,由于阻抗加大,旋转速度变慢。在此实施例中,与上述相同,在纱插通孔7b的全长,即第1中空导向轴7的全长上纱插通孔7b可形成大致方形孔7b3,但如果从纱插通孔7b的前端部7a的前端面7a’开始,形成最长仅为构成纱条V的纤维v的平均纤维长的长度的大致方形孔7b3,如上所述,可使在圆周方向上旋转的反转纤维v1的旋转速度充分地变化。The embodiment shown in FIG. 5 and FIG. 6 is a case where a substantially square hole 7b3 is formed. When the reversed fiber v1 rotating in the circumferential direction passes through the corner 7b3' of the substantially square hole 7b3, the rotation speed is increased due to the increased impedance. slow down. In this embodiment, similar to the above, the
此外,形成于第1中空导向轴7上的纱插通孔7b的形状,并不仅限定于上述的纵长孔7b1或椭圆孔7b2及大致方孔7b3,从前端部7a侧所见到的纱插通孔7b的形状只要为非圆形即可。In addition, the shape of the
此外,在上述实施例中,中空导向轴部件S由:由第1中空导向轴7与第2中空导向轴8构成的前部中空导向轴部S1;由多个导向板9a、9b、9c构成的导向板部9;以及后部中空导向轴部S2构成,但中空导向轴部件S也可仅由第1中空导向轴7构成。In addition, in the above-mentioned embodiment, the hollow guide shaft member S is composed of: the front hollow guide shaft portion S1 composed of the first
以下利用图7—图11对另一个实施例说明有关本发明的特征部分的结构。图7—图11的例中,纱插通孔7b的断面形状在全长上为圆形(正圆),对第1中空导向轴7的前端部7a的外周形状进行改良,以达到本发明的目的。Next, the structure of the characteristic part of the present invention will be described for another embodiment using FIGS. 7-11. In the examples of Fig. 7-Fig. 11, the cross-sectional shape of the
本发明人研究的结果为,通过从喷头1的空气喷射孔1a喷射的喷射空气而在第1中空导向轴7的前端7a(反转纤维v1的接触领域)的周围形成的旋转气流,当反转纤维v1在第1中空导向轴7的前端部7a的圆周方向上以大致一定的速度旋转时,反转纤维v1不会紊乱,纺出的纱线产生的绒毛较少,而在第1中空导向轴7的前端部7a,抑制圆周方向旋转的反转纤维v1的旋转力,使反转纤维v1的速度部分地变化时,反转纤维v1的纤维后端部v1”容易从第1中空导向轴7的前端部7a的外周面离开,使纺出的纱线产生较多绒毛的同时,抑制了纱线的卷绕纤维的卷紧。即,反转纤维v1的旋转速度在圆周方向上积极地变化时,绒毛数增加,可以制造出柔软的纱线。As a result of the research of the present inventors, the swirling airflow formed around the
在第1中空导向轴7的前端部7a,为了使在圆周方向旋转的反转纤维v1的旋转速度变化,在图7所示的实施例中,第1中空导向轴7的前端细的前端部7a的外周面7a’在与第1中空导向轴7的轴线垂直的断面的形状为非圆形。在图7所示的实施例中,将形成圆锥台状的第1中空导向轴7的前端部7a的外周7a’的一部分从其下部向前端面7a1削去,通过从前端面向轴方向形成特定长度的平面7a1,使与第1中空导向轴7的轴线垂直的断面的形状为非圆形。也可在第1中空导向轴7的全长上,使与第1中空导向轴7的轴线垂直的断面的形状为非圆形,但如果形成从前端面7a”开始最长仅为构成纱条V的纤维v的平均纤维长的长度的非圆形,则如上所述,可使在圆周方向上旋转的反转纤维v1的旋转速度充分地变化。此外,前端部7a为前端卷绕着在纱插通孔7b的反转纤维v1的区域,在前端部7a的下方侧,通过锥部7c设置有大直径部7d。纱插通孔7b以贯通前端部7a、锥部7c及大直径部7d的状态形成。In the
如上所述,通过在圆锥台状的第1中空导向轴7的前端部7a的外周面7a’上形成平坦面7a1,反转纤维v从由平坦面7a1形成的平直部开始,向未形成平坦面7a1的曲部移动的位置,对反转纤维v产生制动,抑制在圆周方向旋转的反转纤维的旋转力,可以使反转纤维v1的旋转速度部分地产生变化。As described above, by forming the flat surface 7a1 on the outer
在图7中,示出了上述的平坦面7a1为相隔180度,即相对状态地形成2面的例子,在图8中,示出了各相隔90度,形成4个面的平坦面7a1的例子。形成的平坦面7a1的面数并不限定于如图7或图8的2个面或4个面,可以包含1个面或3个面的奇数在内的多个面以大致等间隔地形成。平坦面7a1的个数与作为表示纱强度的离散情况数值的均匀度的关系为,平坦面7a1形成2面的情况与平坦面为1面的情况相比,纱强度的均匀度要好,即,纱强度的离散情况少。此外,在平坦面7a1的数量为3个(奇数)和4个(偶数)的场合中,4个(偶数)的情况下与安装第1中空导向轴7的朝向(平坦面7a1朝向正上方或曲面部朝向正上方)无关,纱强度的均匀度要好。In FIG. 7, an example in which the above-mentioned flat surface 7a1 is formed at a distance of 180 degrees, that is, two surfaces are formed in an opposing state is shown. In FIG. 8, an example in which four flat surfaces 7a1 are formed at 90 degrees apart is shown example. The number of flat surfaces 7a1 to be formed is not limited to two or four as shown in FIG. 7 or FIG. . The relationship between the number of flat surfaces 7a1 and the uniformity which is a numerical value representing the discreteness of the yarn strength is that the uniformity of the yarn strength is better when the flat surface 7a1 is formed into two surfaces than when the flat surface is one surface, that is, There is little variation in the yarn strength. In addition, when the number of flat surfaces 7a1 is 3 (odd number) and 4 (even number), in the case of 4 (even number), it is different from the direction in which the first
正如上述,通过使第1中空导向轴7的前端细的前端部7a的外周面7a’的形状,在与第1中空导向轴7的轴线垂直的断面的形状为非圆形,能够抑制在圆周方向上旋转的反转纤维v1的旋转力,能够使反转纤维v1的旋转速度部分地发生变化,从而,纺出的纱线产生的绒毛增加,不会降低生成的纱线强度,能够制造绒毛多,柔软的纱线。例如在使用图1所示的第1中空导向轴7的场合,单位长度的绒毛数量大约为3倍。As mentioned above, by making the shape of the outer
此外,通过使第1中空导向轴7的前端部7a的外周面的形状例如在圆周方向部分地使弯曲度不同,成为椭圆形,以构成上述的非圆形。In addition, the shape of the outer peripheral surface of the
图9所示的实施例为在圆锥台状的第1中空导向轴7的前端部7a的外周面7a’或前端面7a”上形成凸部7a2。在图9所示的实施例中,示出了凸部7a2形成于前端部7a的外周面7a与前端面7a”界面上的例子,但只要是在不插入纱插通孔7b、勾住反转纤维v1的后端部v1”、减慢反转纤维v1的旋转速度的位置,可以设置于任何地方。The embodiment shown in Fig. 9 is to form the convex part 7a2 on the outer
由于设置了这样的凸部7a2,反转纤维v1在被凸部7a2挂住的情况下,抑制了在圆周方向旋转的反转纤维v1的旋转力,使其旋转速度变慢,而在凸部7a2以外的区域,由于其旋转速度变慢,在圆周方向旋转的反转纤维v1的旋转速度发生变化。此外,凸部7a2如图9所示,最好形成于前端面7a”的外周部(前端部7a的外周面7a’和前端面7a”的界面)上。Due to the provision of such a convex portion 7a2, when the inverted fiber v1 is caught by the convex portion 7a2, the rotational force of the inverted fiber v1 rotating in the circumferential direction is suppressed, and the rotational speed is slowed down, while the convex portion In regions other than 7a2, the rotational speed of the inverted fiber v1 rotating in the circumferential direction changes because the rotational speed becomes slower. In addition, as shown in Fig. 9, the convex portion 7a2 is preferably formed on the outer peripheral portion of the
图10所示的实施例为,在圆锥台状的第1中空导向轴7的前端部7a的外周面7a’上,在圆周方向上以适当间隔形成朝向前端7a”的槽部7a3。这样,由于从前端面7a”形成在轴向上特定长度的槽部7a3,在反转纤维v1进入槽部7a3的场合,抑制了在圆周方向旋转的反转纤维v1的旋转力,使其旋转速度变慢,此外,在未进入槽部7a3的状态下,其旋转速度加快,从而改变了圆周方向旋转的反转纤维v1的旋转速度。In the embodiment shown in FIG. 10, grooves 7a3 toward the
图11所示的实施例为,在圆锥台状的第1中空导向轴7的前端部7a的前端面7a”上形成十字状的4个槽部7a4。这样,由于在前端面7a”上形成槽部7a4,反转纤维v1在进入槽部7a4的场合,抑制了在圆周方向旋转的反转纤维v1的旋转力,使其旋转速度变慢,此外,在未进入槽部7a4的状态下,其旋转速度加快,从而改变了圆周方向旋转的反转纤维v1的旋转速度。形成于前端面7a”上的槽部7a4可以具有偶数或奇数的适当数量。但从与安装朝向无关、纱强度良好的观点出发,最好至少形成4个槽部7a4。In the embodiment shown in Fig. 11, four cross-shaped grooves 7a4 are formed on the
再者,除了可以使第1中空导向轴7的前端细的前端部7a的外周面7a’的形状,在与第1中空导向轴7的轴线垂直的断面形成非圆形外,还可以形成凸部7a2或槽部7a3、7a4。此外,在第1中空导向轴7的前端部7a的外周面7a’或前端面7a”上形成凸部7a2或槽部7a3、7a4基础上,还可以再使前端部7a的外周面7a’的断面形状为非圆形。Furthermore, in addition to making the shape of the outer
此外,在图7—图11各实施例中,从第1中空导向轴7的入口侧所见到的前端面7a”的外周形状最好为非圆形。In addition, in each of the embodiments shown in FIGS. 7 to 11, the outer peripheral shape of the
在上述的实施例中,示出了在第1中空导向轴7的前端部7a上分别单独分开地形成平坦面7a1、或凸部a2或槽部7a3、7a4的例子,但在形成平坦面7a1的基础上还可以再形成凸部7a2或槽部7a3、7a4。并且,除了上述的实施例外,为了同样地使反转纤维v1的旋转速度变化的目的,也可使前端部7a的纱插通孔7b的形状为非圆形(椭圆形)。In the above-mentioned embodiment, the example in which the flat surface 7a1, or the convex portion a2, or the groove portions 7a3, 7a4 are separately formed on the
在上述的实施例中,示出了中空导向轴部件S由第1中空导向轴7与第2中空导向轴8构成的前部中空导向轴部S1、由多个导向板9a、9b、9c构成的导向板部9、以及后部中空导向轴部S2构成的例子,但中空导向轴部件S也可仅由第1中空导向轴7构成。In the above-mentioned embodiment, the hollow guide shaft member S is shown to be composed of the front hollow guide shaft part S1 composed of the first
以上,对于本发明的特征结构,利用图1—图6对改善第1中空导向轴7的纱插通孔7b的断面形状的例子进行了说明,并利用图7—图11对改善第1中空导向轴7的前端部7a的外周形状的例子进行了说明,但各实施例不仅是可分别单独地实施,也可为2个或3个以上的实施例组合地实施。As above, regarding the characteristic structure of the present invention, an example of improving the cross-sectional shape of the
根据本发明,由于中空导向轴部件的前端部中纱插通孔的断面形成非圆形状,可以使反转纤维的旋转速度在圆周方向上发生变化,可以制造不降低纱强度,绒毛数多且具有柔软感触的纱线。从而通过将利用本发明的纺纱装置制造的纱线进行织造,可制造出具有柔软感触布制品。此外,由于不需变更喷嘴部件的喷嘴压(喷射压),能够维持纺纱上最适宜的流量,防止因纱支数等产生物性值的偏差。According to the present invention, since the cross-section of the yarn insertion hole in the front end of the hollow guide shaft member is formed in a non-circular shape, the rotational speed of the reversed fiber can be changed in the circumferential direction, and it is possible to manufacture yarns with a large number of fluffs and without reducing the yarn strength. Yarn with a soft touch. Therefore, by weaving the yarn produced by the spinning device of the present invention, a soft-touch cloth product can be produced. In addition, since there is no need to change the nozzle pressure (jet pressure) of the nozzle member, it is possible to maintain an optimum flow rate for spinning and prevent variations in physical property values due to yarn count and the like.
此外,由于中空导向轴部件的前端中纱插通孔的断面形状为纵长形状或椭圆孔,可以使反转纤维的旋转速度在圆周方向上平滑地变化。防止断纱等的发生。In addition, since the cross-sectional shape of the yarn insertion hole in the front end of the hollow guide shaft member is an elongated shape or an elliptical hole, the rotational speed of the reversed fiber can be smoothly changed in the circumferential direction. Prevent yarn breakage, etc. from occurring.
此外,由于形成为非圆形状的纱插通孔长度从位于中空导向轴部件的前端面上的纱插通孔入口开始,最长为构成纤维束的纤维的平均长度,可仅使与反转纤维的旋转有关的部分(影响反转纤维的旋转速度部分)为非圆形状,而与反转纤维的旋转无关部分的断面为圆形,能够维持中空导向轴部件的纱插通孔内平滑的空气流,能够防止生成的纱线质量低下。In addition, since the length of the yarn insertion hole formed in a non-circular shape starts from the entrance of the yarn insertion hole located on the front end surface of the hollow guide shaft member, and reaches the longest average length of the fibers constituting the fiber bundle, it is possible to reverse the The part related to the rotation of the fiber (the part that affects the rotation speed of the reversed fiber) is non-circular, while the cross section of the part not related to the rotation of the reversed fiber is circular, and the smoothness in the yarn insertion hole of the hollow guide shaft member can be maintained. The air flow prevents poor quality of the produced yarn.
根据本发明,由于在作为反转纤维的接触区域的中空导向轴部件前端部的外周上,设置有使反转纤维的旋转速度在圆周方向上部分变化的抑制部,可以使反转纤维的旋转速度在圆周方向产生积极的变化,能够制造不降低纱强度,绒毛数多,具有柔软感触的纱线。从而,这样的纱线所织成的布制品的柔软感增大。此外,由于抑制了纱线的卷绕纤维的张紧,纱自身的回转力矩减小,能够使后续工序的纱的解舒性及染色性提高。According to the present invention, since the outer circumference of the front end portion of the hollow guide shaft member, which is the contact area of the reversed fiber, is provided with a suppressing portion that partially changes the rotational speed of the reversed fiber in the circumferential direction, the rotation speed of the reversed fiber can be reduced. The speed changes positively in the circumferential direction, and it is possible to produce a yarn with a high pile count and a soft touch without reducing the yarn strength. Therefore, the softness of the cloth products woven with such yarns increases. In addition, since the tension of the winding fibers of the yarn is suppressed, the rotational moment of the yarn itself is reduced, and the unwinding property and dyeability of the yarn in the subsequent process can be improved.
此外,由于在中空导向轴部件的前端部的外周面上,形成作为抑制部的平坦面,或者形成作为抑制部的凸部或槽部,能够使反转纤维的旋转速度在圆周方向上有效地变化。In addition, since the flat surface as the suppressing portion is formed on the outer peripheral surface of the front end portion of the hollow guide shaft member, or the convex portion or the groove portion is formed as the suppressing portion, the rotation speed of the reversed fiber can be effectively adjusted in the circumferential direction. Variety.
此外,由于在中空导向轴部件的前端部的前端面上,形成作为抑制部的十字状的槽部,也能够使反转纤维的旋转速度在圆周方向上有效地变化。In addition, since the cross-shaped groove portion as the restraining portion is formed on the front end surface of the front end portion of the hollow guide shaft member, the rotation speed of the inverted fiber can also be effectively changed in the circumferential direction.
根据本发明,通过使中空导向轴部件前端部中反转纤维接触区域的外周的形状,在与中空导向轴部件的轴线垂直的断面形成非圆形,使反转纤维的旋转速度在圆周方向上积极地变化,能够制造不降低纱强度,绒毛数多,具有柔软感触的纱线。从而,这样的纱线所织成的布制品的柔软感增大。此外,由于抑制了纱线的卷绕纤维的张紧,纱自身的回转力矩减小,能够使后续工序的纱的解舒性及染色性提高。According to the present invention, by making the shape of the outer periphery of the reversed fiber contact region in the front end of the hollow guide shaft member, the section perpendicular to the axis of the hollow guide shaft member is formed non-circular, so that the rotational speed of the reversed fiber is increased in the circumferential direction. By positively changing, it is possible to manufacture a yarn with a large number of piles and a soft touch without reducing the yarn strength. Therefore, the softness of the cloth products woven with such yarns increases. In addition, since the tension of the winding fibers of the yarn is suppressed, the rotational moment of the yarn itself is reduced, and the unwinding property and dyeability of the yarn in the subsequent process can be improved.
