参考图1，其示出了自动接头单元1的抽吸组件的示意性侧视图，解释了自动接头单元1的操作。
Referring to Fig. 1 showing a schematic side view of a suction assembly of an automatic piecing unit (1), operation of the automatic piecing unit (1) is explained.
自动接头单元1沿着环锭纺纱机的通道纵向移动。
The automatic piecing unit (1) moves longitudinally along the aisle of a ring spinning machine.
环锭纺纱机能够将纱线卷绕到安装于纺纱纱锭的线筒上，即，所谓的纬管4。
The ring spinning machine is capable of winding yarn onto a bobbin mounted to spinning spindle, so called cop (4).
当在纺纱程序中发生纱线断裂时，断纱丝缠结在纺纱纬管4中。
When yarn breakage occurs in the spinning sequence, a broken yarn thread gets entangled in the spinning cop (4).
为了能够对纱线进行接头，必须将断裂的或缠结的纱线端部从纬管4分离。
To enable yarn piecing, the broken or entangled yarn end has to be detached from the cop (4).
自动接头单元1的抽吸组件提供所需的抽吸，以从纬管4拾取断纱端部。
A suction assembly of the automatic piecing unit (1) provides the required suction to pick the broken yarn end from the cop (4).
抽吸组件包括抽吸管2，该抽吸管可为柱形的形状，并可具有抽吸嘴/开口3。
The suction assembly comprises a suction pipe (2) that may be cylindrical in shape, and may having a suction mouth / opening (3).
抽吸管2在纬管4的顶部以预定高度移位，以便从纬管4抽吸断纱端部。
The suction pipe (2) is displaced at a predetermined height at the top of the cop (4) so as to suck the broken yarn end from the cop (4).
如图1所示，抽吸组件设置有文丘里喷射件而不是抽吸马达，以用于从纬管4拾取断纱端部。
As shown in Fig. 1, the suction assembly is provided with a venturi jet instead of suction motor, for picking the broken yarn end from the cop (4).
优选地，可使用两个文丘里喷射件(即，第一文丘里喷射件5a和第二文丘里喷射件5b)来从纬管4抽吸断纱端部。
Preferably, two venturi jets i.e. a first venturi jet (5a) and a second venturi jet (5b) may be used to suck the broken yarn end from the cop (4).
作为一个实施例，还可使用多个文丘里喷射件。
As an embodiment, multiple venturi jets can also be used.
第一文丘里喷射件5a邻近于抽吸管2固定。
The first venturi jet (5a) is fixed adjacent to the suction pipe (2).
第二文丘里喷射件5b远离位于抽吸组件的更远端处的抽吸嘴3固定，如图1所示。
The second venturi jet (5b) is fixed away from the suction mouth (3) at the farther end of the suction assembly as shown in Fig. 1.
来自压力供应端口或环锭纺纱机抽吸单元或纺纱厂抽吸单元或任何源的压缩空气可在第一文丘里喷射件5a和第二文丘里喷射件5b内部依次通过。
Compressed air from a pressure supply port or the ring spinning machine suction unit or spinning mill suction unit or any source may be passed inside the first venturi jet (5a) and the second venturi jet (5b) sequentially.
当压缩空气流动到第一文丘里喷射件5a中时，第一文丘里喷射件5a的收缩区段增加压缩空气的流速。
When the compressed air flows into the venturi jet (5a), a constricted section of the first venturi jet (5a) increases the flow velocity of the compressed air.
由于这种过程，所以在抽吸嘴3中产生真空，由于文丘里效应，该真空导致在向上的方向上抽吸，以将断纱端部从纬管4抬起。
Due to this process, a vacuum is created in the suction mouth (3), which causes suction in the upward direction due to the Venturi effect, to lift the broken yarn end from cop (4).
在本发明的一个方面中，抽吸组件的工作顺序如下文所述。
In an aspect of the present invention, working sequence of the suction assembly is as described hereinafter.
压缩空气通过设置在第一文丘里喷射件5a中的入口在第一文丘里喷射件5a内部通过。
The compressed air is passed inside the first venturi jet (5a) through the inlet provided in the first venturi jet (5a).
压缩空气朝向抽吸管2的内侧在出口处离开文丘里喷射件5a，从而在抽吸嘴3内部在向上的方向上产生抽吸效应或真空。
The compressed air leaves the venturi jet (5a) at an outlet towards the inner side of the suction pipe (2), thereby creating a suction effect or vacuum in the upward direction inside the suction mouth (3).
文丘里内管从一端到另一端的变化的直径轮廓在向上的方向上产生所需的抽吸效应。
The varying diameter profile of venturi inner pipe from one end to another creates the desired suction effect in upward direction.
由于该抽吸效应或真空，从纬管4拾取断纱端部，并在抽吸嘴3内部抽吸到抽吸组件中。
Due to the suction effect or vacuum, the broken yarn end from the cop (4) is picked and sucked inside the suction mouth (3) into the suction assembly.
然后可递送所抽吸的断纱端部以用于进行接头操作。
The sucked broken yarn end may be then delivered for piecing operation.
在另一实施例中，第二文丘里喷射件5b可放置在抽吸组件的更远端处。
In another embodiment, the second venturi jet (5b) may be placed at the farther end of the suction assembly.
传感器(未示出)可放置在抽吸管2内靠近第二文丘里喷射件5b，以检测所抽吸的断纱端部。
A sensor (not shown) may be placed inside the suction pipe (2) near the second venturi jet (5b) to detect the sucked broken yarn end.
当在抽吸管2中检测到断纱端部时，传感器位置可提供输出。
The sensor position may provide an output upon detecting the broken yarn end in the suction pipe (2).
基于该输出，可向第二文丘里喷射件5b提供压缩空气。
Based on such output, the second venturi jet (5b) may be provided with compressed air.
同时，可中断向第一文丘里喷射件5a供应压缩空气。
Simultaneously, supply of the compressed air to the first venturi jet (5a) may be cut off.
因此，断纱端部以受控的方式保持在抽吸管2内部而不会从纬管4解绕。
Consequently, the broken yarn end is held inside the suction pipe (2) in a controlled manner without unwinding from the cop (4).
必要时继续执行上述顺序。
The above sequence is continued whenever required.
图2示出了文丘里喷射件5的透视图。
Fig. 2 illustrates a perspective view of venturi jet (5).
压缩空气从入口通过文丘里喷射件5内部。
The compressed air is passed inside the venturi jet (5) from an inlet.
文丘里喷射件5具有渐缩的内轮廓，该渐缩的内轮廓在抽吸管2内部的纬管4的向上的方向上清除文丘里喷射件5的出口处的压缩空气。
The venturi jet (5) has tapered inner profile that purges the compressed air at an outlet of the venturi jet (5) at an upward direction of the cop (4) inside the suction pipe (2).
这在抽吸嘴3处产生抽吸，并从纬管4向上拾取断纱端部。
This creates suction at the mouth (3) and the broken yarn end is picked upwards from the cop (4).
在本发明的另一实施例中，还可使用多个文丘里喷射件。
In another embodiment of the present invention, multiple / plurality of venturi jets can also be used.
所使用的文丘里喷射件可能不限制于一个或两个。
The venturi jet usage may not be limited to one or two.
在一种情况下，由于压缩空气流动所引起的抽吸压力通过单个或多个流动控制而以任何顺序变化。
In one scenario, a suction pressure due to the compressed air flow is varied at any sequence with a single or multiple flow controls.
提供多个流动控制的时间可根据断纱端部的拾取要求而以任何顺序变化。
Timing of providing multiple flow controls may be varied in any sequence according to picking requirement of the broken yarn end.
因此，为了有效地拾取纱线并进行接头，可能需要维持抽吸压力。
As a result, the suction pressure may desirably be maintained for efficient yarn picking and piecing.
作为示例性实施例，用于第一文丘里喷射件5a的抽吸压力维持在合适的操作范围内，优选为50mbar至70mbar，直到断纱端部被从纬管4拾取/抽吸并由邻近于第二文丘里喷射件5b定位的传感器检测到。
As an example embodiment, a suction pressure for the first venturi jet (5a) is maintained in a suitable operating range, preferably 50 mbar to 70 mbar, until the broken yarn end is picked/sucked from the cop (4) and detected by the sensor positioned adjacent to second venturi jet (5b).
然后向第二文丘里喷射件5b提供压缩空气。
Then, the second venturi jet (5b) is provided with compressed air.
同时，中断向第一文丘里喷射件5a供应压缩空气。
Simultaneously, the compressed air supply to first venturi jet (5a) is cut off.
用于第二文丘里喷射件5b的抽吸压力维持在合适的操作范围内，优选为30mbar至50mbar，直到将所抽吸的断纱端部递送以用于接头。
A suction pressure for the second venturi jet (5b) is maintained in a suitable operating range, preferably the range of 30 mbar to 50 mbar, until the sucked broken yarn end is delivered for piecing.
除了文丘里喷射件5之外，还可在纬管4的底部周围设置多个空气喷射件，以帮助抬起断纱端部(未示出)。
In addition to the venturi jet (5), a plurality of air jets may be provided around the bottom of the cop (4) to assist in lifting the broken yarn end (not shown).
该方法可包括使用抽吸组件从纬管4抽吸断纱端部。
The method may comprise sucking a broken yarn end from a cop (4) using a suction assembly.
抽吸组件可包括抽吸管2，该抽吸管具有位于面向纬管4的端部处的抽吸嘴3。
The suction assembly may comprise a suction pipe (2) having a suction mouth (3) present at an end facing the cop (4).
抽吸管2可定位在纬管4上方的预定高度处。
The suction pipe (2) may be positioned at a predetermined height over the cop (4).
至少一个文丘里喷射件5a可与抽吸管2固定，并且文丘里喷射件5a可从压力供应端口接收压缩空气。
At least a venturi jet (5a) may be affixed with the suction pipe (2), and the venture jet (5a) may receive compressed air from a pressure supply port.
压缩空气通过所述文丘里喷射件5a的收缩区段的运动可在抽吸嘴3中产生真空，以将断纱端部从纬管4抽吸到抽吸管2中。
A movement of the compressed air through a constricted section of the said venturi jet (5a) may create vacuum in the suction mouth (3) to suck the broken yarn end from the cop (4) into the suction pipe (2).
因此，上述自动接头单元和用于对环锭纺纱机中的断纱进行自动接头的方法提供了一种用于以成本有效的方式从纬管拾取断纱端部而不需要完全解绕纬管4的可靠的解决方案。
Thus, the above described automatic piecing unit and a method for automatic piecing of broken yarns in a ring spinning machine provides a reliable solution for picking the broken yarn end from the cop without completely unwinding the cop (4) in a cost effective manner.
通过消除对重的抽吸马达的使用而使得自动接头单元1中的空间也显著减小。
Space is also considerably reduced in the automatic piecing unit (1) by eliminating use of heavy suction motor.

Accordingly, the appended claims are intended to include within their scope such processes, machines, means, methods, or steps.
密封剂树脂层的平均厚度优选为20μm～90μm，更优选为40μm～80μm。
The average thickness of the sealant resin layer is preferably 20-90 µm and more preferably 40-80 µm.
设为20μm以上而能够抑制在基底层与基材层之间产生层间剥离，设为90μm以下而能够抑制生产成本。
By setting the average thickness to no less than 20 µm, interlayer separation occurring between the underlayer and the substrate layer can be suppressed and by setting the average thickness to no greater than 90 µm, production costs can be suppressed.
如图6所示，本发明的第三实施方式所涉及的树脂片不使用第二实施方式所示的密封剂树脂层(2)，由毛状体及基底层(1)与基材层(3)直接层叠而成。
The resin sheet according to a third embodiment of the present invention is one in which the hairlike bodies and base layer (1) and the substrate layer (3) are directly laminated without using the sealant resin sheet (2) indicated in the second embodiment, as shown in Figure 6.
即，第三实施方式所涉及的树脂片的层结构从上向下为毛状体及基底层(1)/基材层(3)，具有从第二实施方式所涉及的热塑性树脂片除去密封剂树脂层之后的层结构。
That is, the layer configuration of the resin sheet according to the third embodiment is, from top to bottom, the hairlike bodies and underlayer (1)/the substrate layer (3) and is the layer configuration for the thermoplastic resin sheet according to the second embodiment from which the sealant resin layer has been removed.
此处，毛状体及基底层与第一实施方式及第二实施方式的层相同，因此省略其说明。
Here, the hairlike bodies and underlayer are the same as those in the first embodiment and the second embodiment, so explanation thereof is omitted.
另一方面，优选本实施方式中的基材层(3)相对于基底层具备充分的粘接性。
Meanwhile, the substrate layer (3) in the present embodiment is preferably a layer provided with sufficient adhesion with the underlayer.
另外，在第三实施方式所涉及的树脂片中，作为基材层，优选使用相对于基底层的粘接性优异的热塑性树脂。
Further, in the resin sheet according to the third embodiment, using a thermoplastic resin with excellent adhesion with the underlayer as the substrate layer is preferable.
例如，在基底层为氟系树脂的情况下，可以使用丙烯酸系树脂，在基底层为烯烃系树脂的情况下，可以使用添加有氢化苯乙烯系热塑性弹性体的苯乙烯系树脂组合物。
For example, when the underlayer is a fluorine-based resin, an acrylic resin can be used and when the underlayer is an olefin-based resin, a styrene-based resin composition to which a hydrogenated styrene-based thermoplastic elastomer has been added can be used.
当同时使用耐冲击性聚苯乙烯树脂与氢化苯乙烯系热塑性弹性体时，优选地，相对于90质量份～95质量份的耐冲击性聚苯乙烯树脂而添加5质量份～10质量份的氢化苯乙烯系热塑性弹性体。
When using an impact-resistant polystyrene resin and a hydrogenated styrene-based thermoplastic elastomer in combination, adding 5-10 parts by mass of the hydrogenated styrene-based thermoplastic elastomer with respect to 90-95 parts by mass of the impact-resistant polystyrene resin is preferred.
在该情况下，将氢化苯乙烯系热塑性弹性体的添加量设为5质量份以上而能够使相对于基底层的粘接性变得充分，能够抑制层间剥离的产生，设为10质量份以下而能够抑制生产成本。
In this case, by setting the amount of the hydrogenated styrene-based thermoplastic elastomer added to no less than 5 parts by mass, adhesion with the underlayer becomes sufficient and the occurrence of interlayer separation can be suppressed, and by setting the amount added to no greater than 10 parts by mass, the production costs can be suppressed.
本发明所涉及的树脂片的制造方法包含如下步骤，通过挤出成型法从模具对热塑性树脂进行熔融挤出，并利用实施了凹凸加工的转印辊与接触辊进行铸造而形成毛状体，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。
The manufacturing method of the resin sheet according to the present invention comprises forming hairlike bodies by melt extruding, from a die with an extrusion molding technique, a thermoplastic resin 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 wherein 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, and casting using a transfer roll on which a relief process has been performed and a touch roll.
在某实施方式中，树脂片的制造方法实质上由上述2个工序构成，无需对平均高度不充分的毛状体状突起进行精梳(combing)、擦刷(brushing)等进行拉伸而形成毛状体等的追加工序，通过对片状的热塑性树脂进行铸造而能够提供体现出良好的触感的树脂片。
In certain embodiments, the manufacturing method for the resin sheet essentially comprises the two steps described above and a resin sheet expressing a good tactile sensation can be provided by casting the thermoplastic resin in a sheet form without requiring an additional step such as forming the hairlike bodies by stretching hairlike body protrusions with insufficient average height by combing, brushing, etc.
在单层片或多层树脂片的制作时，可以使用任意的树脂片成型方法。
In the manufacture of a single layer sheet or a multilayer sheet, any resin sheet molding method can be used.
例如能够举出如下方法：在单层的情况下使用1台单轴挤出机，在复数层的情况下使用复数台单轴挤出机，对各原料树脂分别进行熔融挤出、且利用T型模具而获得树脂片。
For example, there are methods for melting and extruding raw resins using a single-screw extruder when the sheet is single layer and multiple single-screw extruders when the sheet is multilayer and obtaining a resin sheet with a T-die.
在多层的情况下，可以使用进料块状体(feed block)、多歧管模具(multi-manifold die)。
When the sheet is multilayer, a feed block or a multi-manifold die can be used.
此外，本发明的树脂片的各实施方式的层结构基本上如前所述，但是，此外，例如，只要未发现物性等的劣化，可以对基材层添加本发明的树脂片、成型容器的制造工序中产生的废料原料，也可以作为进一步的层进行层叠。
Moreover, the layer configurations of the embodiments of the resin sheet of the present application are basically as discussed previously, but beyond these, for example, scrap material generated in a manufacturing process for the resin sheet or molded container of the present invention may be added to the substrate layer and laminated as a further layer so long as degradation of the physical properties, etc. is not observed.
例如，在使用挤出成型方式的情况下，可以利用T型模具法对树脂片进行挤出，利用实施了凹凸加工的转印辊与接触辊进行铸造以对该树脂片的表面赋予毛状体形状，由此制造本发明的树脂片。
For example, when using an extrusion molding technique, the resin sheet according to the present invention can be manufactured by extruding a resin sheet with a T-die technique and casting with a transfer roll on which a relief process has been performed and a touch roll so as to add the shapes of hairlike bodies to a surface of the resin sheet.
作为实施了凹凸加工的转印辊，可以使用通过激光雕刻法、电铸法、蚀刻法、磨机雕刻法等而在辊的表面规则地施加有细微的凹凸的转印辊。
A roll in which a micro-relief has been applied regularly on a surface thereof with a laser engraving or electrocasting method, an etching method, a mill engraving method, etc. can be used as the transfer roll on which a relief process has been performed.
此处，所谓规则是指凹凸并非无规的排列状态、即在一个方向或两个方向上整齐地排列的状态。
Here, regular means that the relief is in an arranged state that is not random, that is, is arranged in an orderly fashion in one direction or in two directions.
作为凹凸部的形状，例如若为凹部的形状，则能举出锥形(圆锥、四棱锥、三棱锥、六棱锥等)、半圆形、矩形(四棱柱)等。
The arrangement of the relief in an embodiment can be selected from a grid arrangement arranged vertically and horizontally, a staggered arrangement, etc. As the shape of the relief part, there are, for example, if a concave shape, funnel-shapes (cone, quadrangular pyramid, triangular pyramid, hexagonal pyramid, etc.), semicircles, rectangles (quadrangular prism), etc. As the size thereof, the diameter of the opening of the concavity, the depth of the concavity, the spacing of the concavity shapes, etc. are from micrometers to hundreds of micrometers.
对转印辊的凹部的间隔进行调节而能够调节毛状体的间隔，对转印辊的凹部深度进行调节而能够调节毛状体高度，由此还能够调节触感。
The spacing of the hairlike bodies can be adjusted by adjusting the spacing of the concavities on the transfer roll and the height of the hairlike bodies can be adjusted by adjusting the depth of the concavities on the transfer roll, and the tactile sensation can also be adjusted thereby.
另外，优选对转印辊表面实施较大的高宽比的凹凸加工。
Further, it is preferable that a relief process with a high aspect ratio be performed on the transfer roll surface.
例如，对转印辊表面加工出凹部形状的情况下的高宽比(凹部深度/凹部开口直径)优选为0.5～6.0。
For example, the aspect ratio (concavity depth/concavity opening diameter) when working concavity shapes into the transfer roll surface is preferably 0.5-6.0.
为了对转印辊表面实施较大的高宽比的凹凸加工，与蚀刻法、喷砂法、磨机雕刻法等相比，激光雕刻法或电铸法适合于在深度方向上进行精密加工的情况，因此特别优选使用。
In performing a high aspect ratio relief process on the transfer roll surface, in comparison with an etching method, a blasting method, a mill engraving method, etc., a laser engraving method or an electrocasting method is suitable when performing fine work in the depth direction and thus is particularly suitably used.
对转印辊表面的至少一部分进行陶瓷热喷涂，优选对该陶瓷热喷涂后的表面进行凹凸加工。
At least part of the transfer roll surface is ceramic sprayed and it is preferable that a relief process is performed on the ceramic-sprayed surface.
通过陶瓷热喷涂而能够提高凹凸的加工性，另外，能够使树脂片稳定地从转印辊脱离。
Due to ceramic spraying, the workability of the relief is improved and the resin sheet can be stably released from the transfer roll.
作为转印辊的材质，例如可以使用金属、陶瓷等，对于其表面可以利用氧化铬(铬氧)、氧化铝、二氧化钛、氧化铝-二氧化钛、或氧化锆进行热喷涂、或镀敷。
For example, metals, ceramics, etc. can be used as the material of the transfer roll and those wherein the surface thereof has been sprayed or plated with chromium oxide (chromia), alumina, titania, alumina-titania, or zirconia can be used.
另一方面，作为接触辊，可以使用各种材质，例如可以使用硅系橡胶、NBR系橡胶、EPT系橡胶、丁基橡胶、氯丁二烯橡胶、氟橡胶制的辊。
Meanwhile, various materials can be used as the touch roll, for example, a roll made from silicone-based rubber, NBR-based rubber, EPT-based rubber, butyl rubber, chloroprene rubber, or fluorine rubber can be used.
在某实施方式中，可以使用橡胶硬度(JIS K 6253)为40～100的接触辊。
In certain embodiments, a touch roll with a rubber hardness (JIS K 6253) of 40-100 can be used.
另外，可以在接触辊的表面形成特氟龙(Teflon，注册商标)层。
Further, a Teflon® layer may be formed on the surface of the touch roll.
可以使用上述转印辊及接触辊的辊组而制造本实施方式的树脂片。
The resin sheet of the present embodiment can be manufactured by using a roll set of the above transfer roll and touch roll.
在某实施方式中，将转印辊的温度调节为热塑性树脂的可拉伸温度、且使得探针粘性测定中的热塑性树脂的附着力达到0.05N/mm2～0.25N/mm2的温度或者比该温度低0℃～80℃的温度，将转印辊与接触辊的夹送压力(pinch pressure)设为30Kg/cm2～120Kg/cm2而进行铸造，由此能够制造本实施方式的树脂片。
In certain embodiments, the resin sheet of the present embodiment can be manufactured by adjusting the temperature of the transfer roll to the temperature of the thermoplastic resin at which elongation is possible and the temperature at which the adhesive force of the thermoplastic resin in probe tack measurement is 0.05-0.25 N/mm2 or a temperature 0-80°C lower than that and casting with a pinch pressure between the transfer roll and the touch roll of 30-120 Kg/cm2.
关于铸造的树脂片，利用夹送辊(pinchroll)等以0.5m/分钟～30m/分钟、1m/分钟～5m/分钟或2m/分钟～4m/分钟的线速度进行拉取。
The cast resin sheet is taken in at a line speed of 0.5-30 m/minute, 1-5 m/minute, or 2-4 m/minute using a pinch roll, etc.
利用如下热塑性树脂能够获得具有毛状体的平均高度为100μm以上1200μm以下、毛状体的平均直径为1μm以上50μm以下、毛状体的平均间隔为20μm以上200μm以下的表面形状的树脂片，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。
By using a thermoplastic resin 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, a resin sheet having a surface shape in which the average height of the hairlike bodies is no less than 100 µm and no greater than 1,200 µm, the average diameter of the hairlike bodies is no less than 1 µm and no greater than 50 µm, and the average spacing of the hairlike bodies is no less than 20 µm and no greater than 200 µm can be obtained.
应当理解，在将以0.5(单位：S-1)的应变速率在可拉伸温度下测定所得的拉伸粘度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，在斜率(logη/logt)并非0.5以下的情况下，树脂的弹性变形动作强烈而未形成毛状体(即便暂时伸长也会收缩)。
In cases in which the slope (log η/log t) in the interval 0.1 < t < 1.0 in 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 is not 0.5 or less, it is thought that the elastic deformation behavior of the resin strongly causes hairlike bodies not to be formed (even if stretched once, these shrink).
另外，作为使得探针粘性测定中的附着力达到0.05N/mm2～0.25N/mm2的温度范围与可拉伸温度不重叠的状况，在可拉伸温度升高而不重叠的情况下，能够预想到相对于凹凸转印辊的粘着在该温度区域变得过强，产生树脂片卷绕于转印辊的故障、或为了强力地从转印辊剥离而造成树脂片的外观不良。
Further, in cases in which, as conditions in which the temperature range in which the adhesive force in probe tack measurement is 0.05-0.25 N/mm2 does not overlap with the temperature at which elongation is possible, the temperature at which elongation is possible increases and does not overlap, adhesion to the relief transfer roll at the same temperature range becomes too strong and trouble winding the resin sheet on the transfer roll arises and this is expected to be connected to poor external appearance of the resin sheet due to strongly peeling the sheet from the transfer roll.
