内螺纹102的谷部的截面形状最终仿效设置在该平行螺纹51的凸部14的截面形状而被加工，如图5的(D)所示，后续的平行螺纹51进入到所成形的内螺纹102，最终被紧固固定。
Although the parallel screw thread 51 is illustrated as an example, the same is also applicable to a tapered screw thread, wherein a screw thread crest is denoted by 5a, a pressure side flank is denoted by 5b, and a clearance side flank is denoted by 5a.
关于该方式的凸部14，在内螺纹的加工时，如图7的(A)所示，旋入方向的凸部端面14d成为从螺纹的顶部侧的端缘位置朝向凸部14的顶部侧端缘，朝螺纹5的旋入方向的相反方向W2牙峰高度逐渐增加的方向立起的倾斜面，因此使得底孔101顺畅地塑性变形来加工内螺纹。
In this first modification, a pressure side flank 14b of the parallel screw thread 51 having the convex portion 14 includes a crest side flank portion 14b1, which is a pressure side convex flank, and a root side flank portion 14b2 which is constituted by the pressure side flank 5b of the parallel screw thread 51.
此外，作为仿效凸部14的截面形状而成形的内螺纹102，压力侧牙侧102a包括顶部侧牙侧部102a1和谷部侧牙侧部102a2，从而成为在该2个牙侧部的边界形成有拐点Q1的形状。
A boundary between these two flank portions 14b1, 14b2 becomes a point of inflexion P1, and flank angles of these flank portions have the following relation: (a flank angle θa of the root side flank portion 14b2) > (a flank angle θb of the crest side flank portion 14b1).
因此，紧固时，平行螺纹51的压力侧牙侧51a与内螺纹102的压力侧牙侧102a的谷部侧牙侧部102a2抵接。
In this example, the flank angle θa of the root side flank portion 14b2 is equal to the flank angle θa1 of the pressure side flank 5b of the parallel screw thread 51, and a corner C1 between the crest side flank portion 14b1 and a convex crest 14a is in abutment with a pressure side flank 201b of an internal screw 201.
此外，关于凸部24的截面，为了与平行螺纹51进行比较而采用虚线(双点划线)来表示平行螺纹51的牙峰形状。
Here, note that in this example, the root side flank portion 14b2 is constituted by the pressure side flank 5b of the parallel screw thread 51, but it may be constituted by the convex portion.
此外，作为非承载侧凸部牙侧24c，牙侧角比平行螺纹51的非承载侧牙侧5c的牙侧角θa2小，且非承载侧凸部牙侧24c在谷部处与螺纹5的非承载侧牙侧5c无高低差。
In addition, a clearance side convex flank 14c has a flank angle which is smaller than the flank angle θa2 of the clearance side flank 5c of the parallel screw thread 51, and the clearance side convex flank 14c has no step formed in its root portion with the clearance side flank 5c of the screw thread 5.
此外，非承载侧凸部牙侧24c与凸部顶部24a的角部C2抵接于内螺纹201的非承载侧牙侧201c，且角部C2附有曲率半径。
Moreover, a corner C2 between the clearance side convex flank 14c and the convex crest 14a is in abutment with a clearance side flank 201c of the internal screw 201, and the corner C2 is rounded.
图7的(B)是从旋入方向的凸部端面24d斜面观察上述的凸部24的部分立体图。
Fig. 7A is a partial perspective view looking obliquely at a convex portion end face 14d in the screw driving direction of the convex portion 14.
凸部端面24d与上述的实施方式同样地，朝向螺纹顶部5a以根部侧朝旋入方向前方突出的方向倾斜。
Similar to the above-mentioned embodiment, the convex portion end face 14d inclines in a direction in which a root side portion thereof protrudes forward in the screw driving direction W1 toward the screw thread crest 5a.
即，旋入侧人凸部端面24d成为从螺纹顶部5a侧的端缘朝向凸部顶部24a侧的端缘，以朝螺纹5的旋入方向的相反方向W2螺纹高度逐渐增高的方式而立起直至凸部24的顶部24a的倾斜面。
That is, the convex portion end face 14d at the screw driving side is a slope or inclined surface which gradually rises up from an end edge at the side of the screw thread crest 5a toward an end edge at the side of the convex crest 14a in a direction W2 opposite to the screw driving direction of the screw thread 5, and leads to the crest 14a of the convex portion 14.
凸部端面24d包括从凸部顶部24a至螺纹顶部侧的端缘的梯形状的顶部区域24d1、和从顶部区域24d1分支的、沿压力侧凸部牙侧24b及非承载侧凸部牙侧24c的旋入方向的端缘呈倒V字状延伸的压力侧牙侧端部区域24d2及非承载侧牙侧端部区域24d3。
The convex portion end face 14d is provided with a crest region 14d1 of a trapezoidal shape extending from the convex crest 14a to an end edge at the side of the screw thread crest, and a pressure side flank end region 14d2 and a clearance side flank end region 14d3 branching from the crest region 14d1 and extending in an inverted V shape along the crest side flank portion 14b1 of the pressure side flank 14b and an end edge in the screw driving direction of the clearance side convex flank 14c.
压力侧凸部牙侧24b侧的牙侧端部区域24d2成为包括从顶部区域24d1至第一拐点P21的第一区域24d2a和以第二拐点P22为顶点的三角形状的第二区域24d2b的结构，与变形例1相比稍大。
The pressure side flank end region 14d2 is shorter than the clearance side flank end region 14d3.
(作为异物去除用螺栓来使用的情况)
(Use of the External Screw Member as a Bolt for removing Foreign Matter)
在作为异物去除用螺栓来使用的情况下，如图6的(A)所示，关于该变形例2，仅凸部顶部24a与压力侧凸部牙侧24b及非承载侧凸部牙侧24c的角部接触内螺纹201，因此接触压集中作用于异物，从而能够有效地去除涂装、飞溅物等异物。
In cases where the external screw member is used as a bolt for removing foreign matter, as illustrated in Fig. 5A, only a corner formed by the convex crest 14a, the pressure side flank 14b and the clearance side convex flank 14c is in contact with the internal screw 201, and hence, contact pressure can act intensively on foreign matter, so that the foreign matter such as painting, coating, sputter, etc., can be removed in an efficient manner.
此外，尽管存在凸部24的凸部顶部24a侧的角部部分接触的结构，但是因内螺纹与外螺纹的离心而会在比其更广的范围内剥离。
In addition, although it is configured such that the corner of the convex portion 14 at the side of the convex crest 14a is in partial contact with the internal screw 201, the foreign matter can be peeled or exfoliated in a wider area than a partial contact area due to the eccentricity (i.e., eccentric movement) of the bolt or external screw member relative to the internal screw member.
而且，通过分别附加在平行螺纹51及锥形螺纹52，从而能够从内螺纹内直径部附近至平行螺纹51的凸部顶部涉及更广范围来进行剥离。
Moreover, by providing the convex portion 14 on each of the parallel screw thread 51 and the tapered screw thread 52, the peeling or exfoliation of the foreign matter can be carried out in a much wider area extending from the vicinity of the inside diameter portion of the internal screw to the convex crest of the parallel screw thread 51.
此外，凸部24的最大直径是从锥形螺纹52起逐渐成为大直径，并且在与内螺纹的压力侧牙侧及非承载侧牙侧的内直径侧抵接的同时被旋入至此，因此从内直径侧逐渐被刮落，最终与内螺纹的里侧抵接而被刮落。
Moreover, the maximum diameter of each convex portion 14 gradually increases from the tapered screw thread 52, and each convex portion 14 is screw driven into the internal screw member, while being in abutment with the inside diameter side portions of the pressure side flank and the clearance side flank of the internal screw, so that foreign matter will be gradually scraped from the inside diameter side of the internal screw, and finally, each convex portion 14 will come into abutment with the inner deep portions of the internal screw, thus scraping off foreign matter therefrom.
因此，即使部分接触，也能够从内直径侧至牙底侧将附着在压力侧牙侧201b及非承载侧牙侧201c的涂装等异物一律刮落。
Accordingly, even with the partial contact, it is possible to scrape off the foreign matter such as painting, coating, etc., adhered to the pressure side flank 201b and the clearance side flank 201c, from the inside diameter side to the thread bottom side in a uniform manner.
图6的(B)图示出凸部24穿过内螺纹201而将内螺纹201的涂装等异物、杂质去除后的状态。
Fig. 5B illustrates a state where the convex portion 14 has passed through the internal screw 201, with foreign matter such as painting, coating, etc., and impurities in the internal screw 201 removed.
根据该状态，后续的平行螺纹51与内螺纹201卡合而最终被紧固固定。
From this state, the following parallel screw thread 51 comes into engagement with the internal screw 201, so that the external screw member is finally tightened and fixed to the internal screw member.
(作为自攻螺钉来使用的情况)
(Use of the External Screw Member as a Self-Tapping Screw)
图6的(C)、(D)表示将螺钉部件作为自攻螺钉来使用的状态。
Figs. 5C and 5D, respectively, schematically illustrate the states where the external screw member is used as a self-tapping screw.
如图6的(C)所示，内螺纹的谷部的截面形状最终仿效设置在平行螺纹51的凸部24的截面形状而被加工，如图6的(D)所示，后续的平行螺纹51进入到所成形的内螺纹102，最终被紧固固定。
Fig. 5C illustrates a state where the tapered threaded portion has passed through the prepared hole 101 in the mating member 100, and the convex portion 14 formed in the first turn of the parallel screw thread 51 is formed into a final screw thread shape of the internal screw 102.
关于该方式的凸部24，在内螺纹的加工时，旋入方向的凸部端面24d成为如图7的(B)所示，从螺纹顶部侧的端缘朝向凸部24的顶部侧端缘，朝螺纹5的旋入方向的相反方向W2而立起的倾斜面，因此使底孔101顺畅地塑性变形来加工内螺纹。
The cross sectional shape of the root portion of the internal screw 102 is finally processed or formed by following the cross sectional shape of the convex portion 14 formed in this parallel screw thread 51, and as illustrated in Fig. 5D, the following parallel screw thread 51 advances into the internal screw 102 thus formed, and is finally tightened and fixed thereto.
在该示例中，凸部端面24d的、压力侧的牙侧端部区域24d2除了从顶部24a至第一拐点P21的顶部区域24d2a以外，还包括以第二拐点P22为顶点的第二区域24d2b，因此与图5的示例相比接触面积稍大，但是存在不与底孔直径接触的情况，从而能够抑制旋入扭矩的上升。
With the convex portion 14 of this mode or modification, too, at the time of machining the internal screw, as shown in Fig. 7A, the convex portion end face 14d in the screw driving direction forms an inclined plane in which the height of the screw thread thereof rises in a direction to gradually increase from the position of an end edge of the screw thread 5 at the crest side toward a crest side end edge of the convex portion 14 in the opposite direction W2 to the screw driving direction of the screw thread 5.
此外，能够进一步减少切屑并且能够进一步缩小旋入扭矩。
With such a configuration, the prepared hole 101 can be plastically deformed in a smooth manner thereby to form the internal screw.
此外，作为仿效凸部24的截面形状而成形的内螺纹102，压力侧牙侧102a包括与顶部侧牙侧部24b1对应的顶部侧牙侧部102a1和与中间牙侧部24b3对应的谷部侧牙侧部102a2，从而成为在该2个牙侧部的边界形成有拐点Q2的形状。
In addition, the internal screw 102 formed according to the cross sectional shape of the convex portion 14 is configured such that a pressure side flank 102a has a crest side flank portion 102a1 and a root side flank portion 102a2, and that a point of inflexion Q1 is formed at a boundary between these two flank portions 102a1.
图8中图示出用于说明上述的拐点P1、第一拐点P21及第二拐点P22的最佳范围的冲孔图。
In this second modification, it is configured such that there exist two points of inflexion P21, P22.
拐点P1及第一拐点P21的位置X1设定在从凸部顶部4a、14a、24a起凸部4、14、24的牙峰高度X0(从凸部4、14、24的顶部至螺纹的谷部为止的高度)的35％～55％的范围最佳。
Figs. 6A and 6B, respectively, schematically illustrate the fitting engagement states of the external screw thread with respect to the internal screw thread 201 of the internal screw member 200 with foreign matter adhered thereto, and Figs. 6C and 6D, respectively, schematically illustrate the fitting engagement states of the screw threads in the case of using the external screw member as a self-tapping screw.
当拐点P1、第一拐点P21的位置过于接近凸部顶部4a、14a、24a时，与涂装等异物接触的范围变窄进而使剥离效率变差。
First, the structure of a convex portion will be explained by referring to Fig. 6A.
另一方面，当靠近远离凸部顶部4a、14a、24a的谷部时，倾向于剥离效率变好而扭矩增大。
Fig. 6A also illustrates a convex portion 24 formed in a parallel screw thread 51, and one screw thread or ridge of the parallel screw thread 51 following the convex portion 24.
若将拐点P1、第一拐点P21的位置设为凸部14的牙峰高度的35％～55％程度的话，剥离效率优异且旋入扭矩的增大也能得到抑制。
In addition, in a cross section of the convex portion 24, a thread or ridge shape of the parallel screw thread 51 is shown by an imaginary (phantom) line (an alternate long and two short dashes line) for the sake of comparison with the parallel screw thread 51.
关于第二拐点P22的位置X2，设定在从凸部14的顶部起凸部14的牙峰高度X0的、70％～85％的范围最佳。
In this second modification, an intermediate flank portion 24b3 is arranged between a crest side flank portion 24b1 and a root side flank portion 14b2 of a pressure side convex flank 24b of the parallel screw thread 51 having the convex portion 24.
当第二拐点P22的位置靠近谷部时，第一拐点P21与第二拐点P22之间的空间被放开，从而使剥离的异物滞留的效果变小。
In addition, a concavely curved or bent first point of inflexion P21 is formed at a boundary between the crest side flank portion 24b1 and the intermediate flank portion 24b3, and a convexly curved or bent second point of inflexion P22 is formed between the intermediate flank portion 24b3 and the root side flank portion 24b2.
另一方面，当第二拐点P22的位置靠近顶部时，会形成供异物滞留的空间但却造成空间狭小。
That is, the second point of inflexion P22 is formed closer to the root portion side than the first point of inflexion P21, and is formed of the intermediate flank portion 24b3 having an angle still larger than that of the root side flank portion 24b2.
若将第二拐点P22设定在凸部14的牙峰高度X0的70％～85％的范围，则能够使内螺纹成形时所产生的切屑、从螺帽内周剥离的涂料滞留在第一拐点P21与第二拐点P22之间的空间、而且还能够滞留在第二拐点P22与牙底的范围内。
Also, the flank angles are set such that the flank angle θc of the intermediate flank portion 24b3 is larger than the flank angle θa of the root side flank portion 24b2, and the flank angle θa of the root side flank portion 24b2 is equal to or more than the flank angle θb of the crest side flank portion 24b1.
另外，尽管在图5至图7的示例中在压力侧凸部牙侧设置拐点，使得非承载侧凸部牙侧成为单一角度，但是也可以在非承载侧凸部牙侧设置拐点，以与压力侧凸部牙侧成为对称形状。
In addition, a clearance side convex flank 24c has a flank angle which is smaller than the flank angle θa2 of the clearance side flank 5c of the parallel screw thread 51, and the clearance side convex flank 24c has no step formed in its root portion with the clearance side flank 5c of the screw thread 5.
在基底层与毛状体之间不存在结构边界而是形成为连续相。
A continuous phase is formed without a structural boundary between the underlayer and the hairlike bodies.
不存在结构边界是指基底层与毛状体形成为一体，在它们之间不存在结构方面的明确的边界部。
The absence of a structural boundary means that the underlayer and hairlike bodies are integrally formed and that there is no structurally clear border section therebetween.
另外，形成为连续相是指基底层与毛状体之间无接缝而并非不连续(成为连续相)的状态。
Further, forming a continuous phase means a state in which there are no seams between the underlayer and the hairlike bodies and no discontinuities (is a continuous phase).
在这一点上，与毛状体植入基底层的构造不同。
On this point, the present invention differs from a structure in which hairlike bodies are transplanted to an underlayer.
基底层及毛状体的组成相同，基底层与毛状体的键合可以包含共价键。
The underlayer and hairlike bodies have the same composition and the bonds between the underlayer and the hairlike bodies may include covalent bonds.
所谓共价键是指由2个原子共享电子对而形成的化学键，对于作为单体连结而成的链状分子的热塑性树脂，各聚合物通过共价键而键合，与在聚合物分子间发挥作用的范德华键、氢键相比更强力地键合。
Covalent bonds are chemical bonds formed by an electron pair being shared by two atoms, but in thermoplastic resins which are chain molecules in which the monomers are connected, each polymer is bonded by covalent bonds and is bonded more strongly than by the van der Waals bonds or hydrogen bonds acting between the polymer molecules.
另外，基底层及毛状体也可以源自相同而非不同的固体的热塑性树脂片。
Further, the underlayer and the hairlike bodies may be derived not from separate, but from the same solid thermoplastic resin sheet.
所谓源自相同的固体的热塑性树脂片例如是指基于相同的树脂片而直接或间接地获得毛状体及基底层。
Derived from the same solid thermoplastic resin sheet means, for example, the hairlike bodies and the underlayer being obtained, directly or indirectly, based on the same solid resin sheet.
另外，基底层及毛状体也可以由相同固体的热塑性树脂片形成。
Further, the underlayer and the hairlike bodies may be formed from the same solid thermoplastic resin sheet.
所谓由相同的固体的热塑性树脂片形成是指通过对一个树脂片进行加工而直接形成毛状体及基底层。
Formed from the same solid thermoplastic resin sheet means that the hairlike bodies and the underlayer are directly formed by working a single resin sheet.
基底层与毛状体之间不存在结构边界而是形成为连续相，由此抑制因外在刺激使得毛状体与基底层分离而形成为触感良好的片。
By forming a continuous phase without a structural boundary between the underlayer and the hairlike bodies, the hairlike bodies separating from the underlayer due to an external stimulus is suppressed and the sheet becomes one with a good tactile sensation.
另外，能够通过比植入毛状体的情况少的工序而制造。
Further, manufacturing with fewer steps than when transplanting hairlike bodies can be carried out.
利用热塑性树脂而形成基底层。
The underlayer is formed using a thermoplastic resin.
作为热塑性树脂，可以使用如下热塑性树脂，所述热塑性树脂的特征在于，在将以0.5(单位：S-1)的应变速率在可拉伸温度下测定的拉伸粘度η(t)(单位：Pa·S)设为纵轴、且将拉伸时间t(单位：S)设为横轴的双对数曲线图中，在0.1<t<1.0的区间具有斜率(logη/logt)为0.5以下的区域，探针粘性测定中的附着力为0.05N/mm2～0.25N/mm2的温度范围与可拉伸温度至少一部分重叠。
Thermoplastic resins characterized by having, on a log-log graph having elongational viscosity η(t) (unit: Pa·S) as measured at a strain rate of 0.5 (unit: S-1) and at a temperature at which elongation is possible as the vertical axis and elongation time t (unit: S) as the horizontal axis, a region in which the slope (log η/log t) in the interval 0.1 < t < 1.0 is no greater than 0.5 and by the temperature range in which the adhesive force in probe tack measurement is 0.05-0.25 N/mm2 at least partially overlapping with the temperature at which elongation is possible can be used as the thermoplastic resin.
(可拉伸温度)
(Temperature at which Elongation is Possible)
在本实施方式中，所谓可拉伸温度是指使得热塑性树脂显示出塑性而能够拉伸(例如拉伸成型)的温度。
In the present embodiment, the temperature at which elongation is possible indicates the temperature at which the thermoplastic resin demonstrates plasticity and elongation (for example, stretch molding) becomes possible.
将股线安装于单轴拉伸粘度计，能够根据以各种温度使其拉伸时的股线的状态而判断可拉伸温度。
The temperature at which elongation is possible can be determined from the condition of a strand when the strand is set in a uniaxial elongation viscometer and stretched at various temperatures.
在温度较低的情况下，树脂未显示出塑性(坚硬状态)，从而对股线进行固定的辊会空转。
When the temperature is low, the resin does not demonstrate plasticity (is in a rigid state) and the roll to which the strand is fixed runs idle.
另外，在温度较高的情况下，树脂变为熔融状态，从而无法固定于辊，或者固定拉伸时的拉伸粘度不足1.0×104(单位：Pa·S)而导致股线断裂。
Further, the resin enters a molten state when the temperature is high and cannot be fixed to the roll or the elongational viscosity when fixed to the roll and stretched does not satisfy 1.0×104 (unit: Pa·S) and the strand breaks.
将位于该坚硬状态与熔融状态之间的温度定义为可拉伸温度。
Temperatures positioned between those of the rigid state and the molten state are defined as the temperature at which elongation is possible.
关于本实施方式的热塑性树脂，在将以0.5(单位：S-1)的应变速率在可拉伸温度下测定的拉伸粘度η(t)(单位：Pa·S)设为纵轴、且将拉伸时间t(单位：S)设为横轴的双对数曲线图中，在0.1<t<1.0的区间具有斜率(logη/logt)为0.5以下的区域。
The thermoplastic resin of the present embodiment has, on a log-log graph having elongational viscosity η(t) (unit: Pa·S) as measured at a strain rate of 0.5 (unit: S-1) and at a temperature at which elongation is possible as the vertical axis and elongation time t (unit: S) as the horizontal axis, a region in which the slope (log η/log t) in the interval 0.1 < t < 1.0 is no greater than 0.5.
可以利用市售的拉伸粘度测定机在能够使得热塑性树脂拉伸的温度、例如100℃、110℃、120℃、130℃、140℃、150℃或160℃的测定温度下以0.17S-1、0.5S-1或0.83S-1的应变速率对拉伸粘度进行测定。
Elongational viscosity can be measured using a commercially available elongation viscosity measuring instrument at a strain rate of 0.17, 0.5, or 0.83 S-1 at a measurement temperature that is a temperature at which the thermoplastic resin can be elongated, for example, 100, 110, 120, 130, 140, 150, or 160°C.
热塑性树脂具有如上所述的区域，从而在可拉伸温度下显示出塑性，在进行拉伸成型的情况下，即使在热塑性树脂的拉伸部位相对于拉伸力被释放的情况下也能够维持拉伸的状态而不会大幅收缩。
Due to the thermoplastic resin having a region such as that described above, the thermoplastic resin demonstrates plasticity at the temperature at which elongation is possible and when stretch molding is performed, the resin can maintain the stretched state without greatly shrinking, even when the location of the thermoplastic resin that was stretched has been released from the stretching force.
例如可以利用倾斜式滚珠粘性测试法、滚珠粘性测试法以及探针粘性测试法对热塑性树脂的附着力进行测定。
The adhesive force of the thermoplastic resin can be measured by, for example, an inclined ball tack method, a rolling ball tack method, or a probe tack method.
作为探针粘性测定，存在威泽尔(Wetzel)的方法、神户镰形的方法、哈蒙德(Hammond)的方法、力世科(RHESCA)法。
As probe tack measurements, there are the Wetzel method, the Kanbe/Kamagata method, the Hammond method, and the Rhesca method.
其中，关于除了力世科(RHESCA)法以外的探针粘性测定，使探针从下方接近试样的粘着面置于下方的试样，接触后使探针在下方以恒定速度移动，由此对使探针从粘着面剥离所需的力进行检测。
Among these, probe tack measurements excluding the Rhesca method bring, from below, a probe close to a sample placed with the viscous surface of the sample downwards and detect the force necessary to peel the probe from the adhesive surface by moving the probe downwards at a fixed speed after contact.
关于力世科(RHESCA)法，将试样的粘着面置于上方，从上部将探针按压于粘着面，由此对使其剥离的力进行检测。
The Rhesca method places the adhesive surface of the sample upwards and detects the peeling force by pushing the probe into the adhesive surface from above.
在对加工中途的熔融高分子材料表面的粘着性进行测定的情况下，可以适当地使用力世科(RHESCA)法。
The Rhesca method can be suitably used when measuring the adhesion of a molten polymer material surface during processing.
在本实施方式中，如果附着力处于0.05N/mm2～0.25N/mm2的范围内，则热塑性树脂能够适当地附着于转印辊表面而形成毛状体。
In the present embodiment, if the adhesive force is within the range 0.05-0.25 N/mm2, the thermoplastic resin moderately adheres to the transfer roll surface and the hairlike bodies can be formed.
另外，更优选利用与转印辊表面的材料相同的探针的探针粘性测定中的附着力处于0.10N/mm2～0.20N/mm2的范围内。
Further, the adhesive force in a probe tack measurement using a probe of the same material as the transfer roll surface is more preferably within the range 0.10-0.20 N/mm2.
在某实施方式中，对转印辊表面的材质进行变更、或不仅调节铸造时的温度(热塑性树脂、转印辊以及接触辊的温度)还对转印辊表面使用脱模剂，对转印辊表面的表面粗糙度进行变更，由此能够调节转印辊表面与热塑性树脂的附着性。
In certain embodiments, adhesion between the transfer roll surface and the thermoplastic resin can be adjusted not only by altering the material of the transfer roll surface or adjusting the temperature (the temperature of the thermoplastic resin, the transfer roll, or the touch roll) when casting, but also by using a mold release agent on the transfer roll surface or altering the surface roughness of the transfer roll surface.
热塑性树脂的190℃至300℃的熔融质量流率(MFR,melt mass-flow rate)优选为4g/10分钟以上。
It is preferable that the melt mass flow rate of the thermoplastic resin is no less than 4 g/10 minutes at 190°C to 300°C. By setting the rate to no less than 4 g/10 min, the transferability of the shape of the hairlike bodies can be improved.
此外，熔融质量流率是依据JIS K 7210在190℃至300℃的温度范围的试验温度、载荷(2.16Kg至10.0Kg)的条件下测定所得的值。
The melt mass flow rate conforms to JIS K 7210 and is a value measured under the conditions of a load (2.16 Kg to 10.0 Kg) at a test temperature in the temperature range from 190°C to 300°C.
作为本实施方式的热塑性树脂，可以从包含苯乙烯系树脂、烯烃系树脂、聚氯乙烯树脂、热塑性弹性体、氟系树脂、聚酯系树脂、尼龙系树脂的1种以上的树脂中选择使用。
