实现本发明的最佳方式
以较佳实施例而言，基于具有弹性、轻、薄特性及加强的支撑性，本发明的橡胶复合物可作为鞋类的鞋底或鞋垫使用，但不限于此。如图1A及图1B所示，于一实施例，本发明的橡胶复合物100包含织布层110及包覆织布层110的橡胶层120。织布层110具有上表面112及下表面114，且织布 层110具有由至少一纱线织成的多个网格116。橡胶层120包覆织布层110的上表面112及下表面114，且橡胶层120的一部分122伸入多个网格116中，以位在织布层110的上表面112及下表面114间，使得橡胶层120与织布层110形成互扣结构(interlock structure)。
如图2A所示，于一实施例，织布层110可为由多条经纱110a及纬纱110b编织而成的网格结构，使得多个网格116的平均网格宽度W G较佳为0.2至4毫米(mm)，更佳为0.8至1.2mm，但不以此为限。于另一实施例，如图2B所示，织布层110可为由至少一条纱线针110c针织而成多个纬列110c1及经行110c2构成的网格结构。沿纱线110c针织的蜿蜒路径是定义为纬列110c1，而经行110c2的延伸方向是与纬列110c1的延伸方向相交。也就是说，纬列110c1为织针纱环构成的水平列，经行110c2为交互相接的织针纱环构成的垂直行。多个纬列110c1及经行110c2形成的多个织针纱环则构成多个网格116，且其平均网格宽度W G较佳为0.2至4毫米(mm)，更佳为0.8至1.2mm。在此需注意，依据实际应用，织布层110可具有不同的网格结构，以强化织布层110的延展性或支撑性，不以图2A及图2B所示为限。
织布层110的上表面112及下表面114为纱线110a、110b(或110c)所织成的网格结构的最上表面及最下表面。举例而言，当织布层110为单层结构时，织布层110的上表面112及下表面114间的距离通常为纱线的厚度。当织布层110为多层网格结构时，织布层110的上表面112及下表面114分别由最上层纱线的上表面及最下层纱线的下表面所构成。于较佳实施例中，纱线110a、110b、或110c为一根25丹尼(denier)可承受1000公斤以上重量的强力纱线(较佳为可承受2000公斤)，以使得由其所织成的织布层110可提供较大的支撑强度，不易断裂。举例而言，纱线110a、110b、或110c较佳可为化学纤维纱线或玻璃纤维纱线，例如玻璃纤维强化塑胶(Fiber Glass Reinforced Plastics，FRP)纱线，但不以此为限。如此，可通过使用高强度纱线织成的织布层110提升橡胶复合物100的支撑强度，进而使得橡胶复合物 100可具有相对较薄的厚度及较轻的重量，有利于应用在鞋类的鞋底或鞋垫。
织布层110较佳为镶嵌在橡胶层120中，使得橡胶层120不仅在织布层110的上表面112及下表面114延伸的二维平面(即XY平面)上黏结织布层110，更在织布层110的上表面112及下表面114所夹的厚度方向(即Z方向)上，黏结织布层110的多个网格116的至少一网格的内侧面，以提升橡胶层120与织布层110间的黏结力。也就是说，橡胶层120的橡胶不仅黏结在织布层110的上表面112及下表面114的纱线110a、110b(或110c)上，更存在于多个网格116中，使得橡胶层120的部分橡胶黏结在至少一网格116的内侧面，或者使得黏结在织布层110的上表面112及下表面114的橡胶层120通过织布层110的网格116中交织黏结而形成互扣结构。
于一实施例，橡胶层120伸入多个网格116中的部分122较佳实质完全填塞于多个网格116的至少一个网格中，以使该至少一个网格实质没有空隙。如图1B所示，橡胶层120伸入多个网格116中的部分122较佳实质完全填塞于多个网格116中，以使织布层110中的多个网格116均被橡胶层120的部分122填满而实质没有空隙。也就是说，橡胶层120实质包覆形成多个网格116的纱线110a、110b(或110c)，使得织布层110实质密实地镶嵌在橡胶层120中，但不以此为限。于另一实施例，如图1C所示，橡胶层120伸入多个网格中的部分122a可部分裹住在多个网格116的至少一个网格的内侧面的至少一纱线110a、110b(或110c)。也就是说，依据工艺条件，应用热压成型技术使橡胶层120包覆织布层110时，橡胶层120融化而部分122a流入织布层110的网格116，且橡胶复合物100热压成型后，使得织布层110的网格116中至少有部分被橡胶填入，以提升橡胶层120与织布层110间的黏结力。橡胶层120的材料可包含任何合宜的天然橡胶或合成橡胶，尤其是适合制作鞋底或鞋垫的橡胶材料。
于另一实施例，如图3A及图3B所示，橡胶复合物200包含织布层110、上橡胶层220及下橡胶层230。织布层110可为例如图2A或图2B所示的织布层，并具有上表面112及下表面114，且织布层110具有由至少一纱线织 成的多个网格116。上橡胶层220黏结于织布层110的上表面112，而下橡胶层230黏结于织布层110的下表面114。上橡胶层220及下橡胶层230中的至少一层具有延伸黏结部240，延伸黏结部240通过多个网格116以接合上橡胶层220及下橡胶层230。也就是说，上橡胶层220及下橡胶层230构成类似图1A的橡胶层120，且延伸黏结部240可以是类似于图1A的橡胶层120伸入网格116的部分122(或122a)，较佳是上橡胶层220及下橡胶层230至少其中之一通过网格116连接上橡胶层220及下橡胶层230的部分。
于此实施例，上橡胶层220及下橡胶层230可为材质相同或不同的橡胶层，且延伸黏结部240可为上橡胶层220及下橡胶层230经过热压成型技术融化而流入织布层110的网格116中的部分。橡胶复合物200热压成型后，延伸黏结部240不仅位在织布层110的网格116中，且更将上橡胶层220及下橡胶层230接合在一起。也就是说，织布层110的上表面112及下表面114的纱线分别与上橡胶层220及下橡胶层230黏结，而延伸黏结部240位在网格116中，且延伸黏结部240的上端及下端通过织布层110的网格116分别连接上橡胶层220及下橡胶层230。如此，不仅可加强上橡胶层220及下橡胶层230间的接合，更可提升上橡胶层220及下橡胶层230与织布层110的黏结强度，而使得橡胶复合物200的黏结强度增加，上橡胶层220及下橡胶层230不易与织布层110分离。
于另一实施例，如图4的流程图实施例所示，本发明的橡胶复合物的制造方法包含例如以下步骤。
步骤410，提供由至少一纱线织成的织布层，织布层具有上表面及下表面并具有多个网格。具体而言，于步骤410中，可提供例如图2A或2B所示的织布层110。织布层110可包含由至少一纱线110a、110b(或110c)织成的网格结构。织布层110具有上表面112及下表面114并具有多个网格116。提供织布层110的步骤410可包含提供具有平均网格宽度为0.2至4毫米(mm)的织布层。更具体而言，提供织布层110的步骤410可包含提供使用一根25丹尼可承受1000公斤以上重量(较佳为2000公斤)的纱线形成的织布层。
步骤420，设置上橡胶层于织布层的上表面，且步骤430，设置下橡胶层于织布层的下表面。具体而言，如图5A所示，步骤420及步骤430包含设置相同或不同材质的橡胶层220、230于织布层110的上表面112及下表面114，以形成织布层110夹设于上橡胶层220及下橡胶层230间的组合。于此实施例，上橡胶层220及下橡胶层230的融化温度较佳低于形成织布层110的纱线熔点，使得上橡胶层220及下橡胶层230融化时，织布层110仍保有多个网格116的网格结构。再者，设置上橡胶层220及下橡胶层230的步骤顺序可互换或同时进行，不以图4所示的顺序为限。
步骤440，于模具中热压上橡胶层、织布层及下橡胶层的组合，以使上橡胶层及下橡胶层分别融化黏结于织布层的上表面及下表面，且使上橡胶层及下橡胶层中的至少一层的部分橡胶融化形成延伸黏结部，该延伸黏结部通过多个网格以接合上橡胶层及下橡胶层。具体而言，如图5B所示，模具300包含第一夹具310及第二夹具320。将步骤410～430形成的上橡胶层220、织布层110及下橡胶层230的组合放置于第一夹具310及第二夹具320间。利用第一夹具310及第二夹具320加热且加压上橡胶层220、织布层110及下橡胶层230的组合，以热压成型如图1A或图3A所示的橡胶复合物100或200。具体而言，加热的温度较佳大于上橡胶层220及下橡胶层230的融化温度，以使得上橡胶层220及下橡胶层230分别融化黏结于织布层110的上表面112及下表面114，且加压的力量较佳使上橡胶层220及下橡胶层230中的至少一层的部分融化流入织布层110的多个网格116，以形成接合上橡胶层220及下橡胶层230的延伸黏结部240。此外，加热的温度较佳小于上橡胶层220及下橡胶层230的玻璃转化温度(glass transition temperature,Tg)，以避免上橡胶层220及下橡胶层230硬化失去弹性。
举例而言，于热压步骤440中，热压成型的工艺条件使得延伸黏结部240至少部分黏结于多个网格116的至少一个网格的内侧面，如图1B、1C或3B所示。具体而言，织布层110较佳为镶嵌在橡胶层中，使得橡胶层220、230不仅在织布层110的上表面112及下表面114延伸的二维平面(即XY平 面)上黏结织布层110，更在织布层110的上表面112及下表面114所夹的厚度方向(即Z方向)上，利用延伸黏结部240黏结对应织布层110的多个网格116上/下表面的橡胶层220、230，以提升上橡胶层220与下橡胶层230间，以及上橡胶层220、下橡胶层230与织布层110间的黏结力。也就是说，橡胶层220、230的橡胶不仅可黏结在织布层110的上表面112及下表面114的纱线110a、110b(或110c)上，更存在于多个网格116中形成延伸黏结部240，使得上橡胶层220及下橡胶层230通过延伸黏结部240与织布层110的网格结构立体交织黏结。
由于上述的橡胶复合物100或200在给定的支撑强度下，具有相对较薄的厚度及较轻的重量，使得橡胶复合物100或200非常适合应用于鞋类的鞋底或鞋垫，而不会有一般薄橡胶一拉扯就断裂的问题，可以媲美很厚的橡胶底才能有的强度。如图6A及图6B所示，于一实施例，本发明的鞋底10包含上述的橡胶复合物100或200。具体而言，以橡胶复合物200为例，下橡胶层230具有上表面232及下表面234，其中下橡胶层230的上表面232黏结织布层110的下表面114，而下橡胶层230的下表面234更具有多个突出部236。也就使说，当橡胶复合物100或200应用于鞋底10或鞋垫时，作为鞋底10下表面的橡胶层(例如230)的下表面234可为粗糙表面，以增加摩擦系数，提升防滑效果。
对应于橡胶复合物100或200于鞋底或鞋垫的应用，本发明的制造方法，于热压步骤440中，可使用具有预设图案的模具，以使下橡胶层的下表面更具有多个突出部。具体而言，如图7所示，模具300’包含第一夹具310及第二夹具320’，其中第二夹具320’可为具有多个凹穴图案322的夹具。将步骤410～430形成的上橡胶层220、织布层110及下橡胶层230的组合放置于第一夹具310及第二夹具320’间，且上橡胶层220接触第一夹具310，而下橡胶层230接触第二夹具320’。利用第一夹具310及第二夹具320’加热且加压上橡胶层220、织布层110及下橡胶层230的组合，使得上橡胶层220及下橡胶层230分别融化黏结于织布层110的上表面112及下表面114，且上橡 胶层220及下橡胶层230中的至少一层的部分融化流入织布层110的多个网格116中，以形成接合上橡胶层220及下橡胶层230的延伸黏结部240，更使下橡胶层230中的橡胶流入凹穴图案322，以形成多个突出部236。之后，可通过裁切步骤，将橡胶复合物裁切成鞋底或鞋垫的形状，例如图6A所示，但不以此为限。于另一实施例，可通过预先将织布层110裁切或织成有对应鞋底或鞋垫的形状，再配合模具300或300’的设计，使得热压成型后的橡胶复合物100或200具有相应的鞋底或鞋垫形状，而可免除热压成型后的裁切步骤。
再者，对应不同的鞋类应用，由橡胶复合物100或200制成的鞋底可具有不同的设计。如图8A及图8B所示，鞋底10’包含上橡胶层220、织布层110’及下橡胶层230’。织布层110’包括间隔设置的第一织布210a及第二织布210b。第一织布210a对应于人体脚掌部位，而第二织布210b对应于人体脚跟部位。第一织布210a及第二织布210b的细节可参照前述实施例中织布层110的相关说明，例如具有多个网格116、由纱线110a、110b(或110c)织成等，于此不再赘述。下橡胶层230’包括间隔设置的第一橡胶部230a、第二橡胶部230b及第三橡胶部230c。第一橡胶部230a与第二橡胶部230b黏结于第一织布210a，且第三橡胶部230c黏结于第二织布210b。第一橡胶部230a的侧边具有第一边墙231a，第二橡胶部230b的侧边具有第二边墙231b，第三橡胶部230c的侧边具有第三边墙231c，且第一边墙231a、第二边墙231b及第三边墙231c分别朝上橡胶层220所在的方向突出于上橡胶层220，以界定鞋底空间10a。
具体而言，可对应改变膜具300或300’的设计，使得热压成型后，上橡胶层220的前半部与第一橡胶部230a及第二橡胶部230b的部分橡胶融化流入第一织布210a的网格，而接合上橡胶层220与第一橡胶部230a及第二橡胶部230b。上橡胶层220的后半部与第三橡胶部230c的部分橡胶融化流入第二织布210b的网格，而接合上橡胶层220与第三橡胶部230c。再者，上橡胶层220、第一橡胶部230a、第二橡胶部230b及第三橡胶部230c更可融 化使得部分的橡胶形成对应的第一边墙231a、第二边墙231b及第三边墙231c，而形成鞋底10’。如此，可通过织布层110’分隔设置的第一织布210a及第二织布210b与下橡胶层230’分隔设置的第一橡胶部230a、第二橡胶部230b及第三橡胶部230c，进而增进橡胶鞋底10’弯折性及机能性。再者，第一橡胶部230a、第二橡胶部230b及第三橡胶部230c的下表面也可以形成如上述图6B实施例所述的突出部236，以增加摩擦力进而提升防滑效果。
虽然前述的描述及图式已揭示本发明的较佳实施例，必须了解到各种增添、许多修改和取代可能使用于本发明较佳实施例，而不会脱离如所附申请专利范围所界定的本发明原理的精神及范围。本领域技术人员将可体会，本发明可使用于许多形式、结构、布置、比例、材料、元件和组件的修改。因此，本文于此所揭示的实施例应被视为用以说明本发明，而非用以限制本发明。本发明的范围应由权利要求书范围所界定，并涵盖其合法均等物，并不限于先前的描述。
