Description

具有形成有多个独立气囊的气片的面料及其制造方法
本申请为申请号201710055353.5,申请日为2017年1月25日,发明名称为“具有形成有多个独立气囊的气片的面料及其制造方法”的分案申请。
技术领域
本发明涉及具有形成有多个独立气囊的气片的面料及其制造方法,尤其涉及如下的技术,通过对气囊经线与一般纤维材料的纬线进行织造来制造气囊面料,可使面料的面积扩大至所需的大小,也可通过织造组织之间的缝隙确保通气性,并且由于不需要将用于制造气囊经线的辊子或压力机制造的大,可使气囊面料的制造费用降低。
本发明涉及具有形成有多个独立气囊的气片的面料,更具体涉及如下的具有形成有多个独立气囊的气片的面料,即,通过在内部设置形成有分别以球形或与此类似的形态独立形成且分别在其内部独立填充二氧化碳或氦气的多个气囊的气片,来使各个气囊独立维持,并根据需求在各自适当的环境下独立破裂或维持原型,从而增进使用的便利性,并可使效力持续的长久,因而可使用于消防服或救生衣。
背景技术
以往被视为夕阳产业的纤维产业,近来随着应用尖端技术的各种功能性面料的开发而被视为新型高附加价值产业。
功能性面料通过具有新功能的原丝来织造,或在一般织物的表面由新物质进行涂敷处理,或复合各种原丝来制造新的结构的织物,从而具有在以往的传统纤维中无法实现的特别的或提高的功能的面料。例如,通气性、排汗性、保温性、吸湿性、抗菌性、断热性、耐磨耗性、柔软的触感等相比以往显著提高,或由于具有导电性而遮蔽电磁波或静电,或在活动时可产生电的面料等以往难以想到的具有多种功能的功能性面料正在陆续开发中。
本申请人开发过作为这种功能性面料之一的面料中具有填充二氧化碳或氦等的气体的气囊的面料。这种形成有多个独立气囊的气片可发挥韩国授权专利第10-0964968号中的构成具有气囊的消防用防水防火服内部面料的多孔性的聚氨酯片所无法期待的卓越效果。
即,多孔性的聚氨酯片通过填充在内部的气泡来可使断热性能提高到一定程度,但气泡内的空气随时可以漏出,因此在任何环境下极其难以取得期待的效果,并且难以取得充分的缓冲效果。
但是,在本申请人的现有专利中,由于多个气囊密封于具有充分的拉伸强度的气片内,被填充的气体平时不能漏出,从而可发挥稳定的性能,并且,以在特定高热条件(例如,超过100℃)下破裂并使被填充的气体具有冷却材料的功能的方式设计,因此具有可适用于要求断热和冷却的消防服或需要浮力的救生衣的优点。
如上所述,形成多个独立气囊的气片对于生产具有非常适合消防服或救生衣的功能的特性的面料具有出色的优点,但是难以制造出所需的面积的气片。
即,在制造气片时,在封闭的空间内设置形成有多个气囊成型槽的一对吸引辊子或沿着上下方向进行工作的压力机,在气片进行合并的地点的上游喷射气体,来在两层的气片内一边充填气体,一边利用吸引辊子或压力机使气片贴合,从而以在按照气囊成型槽的形状制造的气囊内填充气体的方式来制造,因此,气片面料的大小局限于吸引辊子或压力机的大小。
并且,由于气片由没有通气性的材料制造,来密封气体,若使用气片面料制作衣服,则很难排出汗,因此在大部分的情况下仅在衣服的一部分使用气片面料,从而具有难以充分发挥所需的功能的问题。
另一方面,镇压火灾及救助性命的消防员等的工作人员为从高温的火焰保护身体的同时,阻断高温的辐射热而穿戴消防用防水防火服。根据特殊防火服标准规格书,这种消防用防水防火服由外料、中间层、里料及毡构成。
外料为由聚苯并咪唑(PBI,Polybenzimidazole)类纤维、聚苯并恶唑(PBO,Polybenzoxazole)类纤维或同等以上的纤维构成的织物,或聚苯并咪唑类纤维、聚苯并恶唑类纤维的防火服构成比率为30%以上,剩余面料成分要使用芳香族聚酰胺类纤维或具有同等以上性能的面料,并其组织应为防撕裂(Rip-Stop)。并且,中间层、里料及毡应使用具有优秀的断热性能的同时具有优秀的透湿和防水性能的材料。而且,里料应为芳香族聚酰胺类纤维或同等以上的柔软并具有好的吸汗力的材料,当在中间层或里料中使用毡时,毡应为与中间层或里料相同的材料。
这种消防用防水防火服使对于热防护性能、重量、里料清洗时间、原材料价格等的基准规格化,目前,韩国规格及国家防火协会(NFPA)规格被详细规定。
根据以往消防用防水防火服的面料的层叠结构,通过外料、中间层、里料及毡能够表现一定程度的热防护性能,但由于表现低于国家防火协会的基准的热防护性能,具有不能从火伤等安全保护使用人员的问题。而且,在身体-里料-毡-防透湿面料的层叠结构中不能发挥透湿性能,使穿戴感不佳,因此,具有使活动性降低的问题。并且,由于毡为与棉相同的材质,清洗后干燥时,干燥时间大致为三日以上,时间很长,因此穿戴完全干燥的消防用防水防火服为止,具有需要消耗过长时间的问题。
为解决这些问题,在韩国专利第10-0964968号的名称为“具有气囊的消防用防水防火服内部面料及利用其的消防用防水防火服”的发明中,公开了由耐热性毡、内部具有形成有气泡的多个气囊的多孔性的聚氨酯片及由具有耐热性的芳香族聚酰胺类纤维构成的芳香族聚酰胺面料依次层叠来构成的具有气囊的消防用防水防火服内部面料,虽然上述聚氨酯片的内部形成有多个气囊,但这种气囊的缓冲效果少,且由于用于阻断防火热气的气体没有填充在内部,具有其热阻断效果不能正常发挥的问题。
并且,以往的救生衣所使用的材料具有如下问题,即,由于填充有厚的合成树脂类的内部填充物,使穿戴感不佳,并因空气含率的降低,使得浮力不佳,且由难以弯曲或不会弯曲的材料来制造,因此制约人体活动性。

具体实施方式
以下参照附图详细说明本发明的优选实施方式。
在对本发明的实施方式进行说明的过程中,省略对本发明所属技术领域的普通技术人员能够显而易见地理解的公知的结构的说明,使得防止混淆本发明的主旨。并且,在参照附图时,应理解附图中示出的线的厚度和结构要素的大小等,为说明的清晰性和便利性而以夸张的方式示出。
第一实施例
图1为示出本发明的第一实施例的气囊面料50的整体结构的立体图,以下参照图1进行详细说明。
本发明的气囊面料50的特征在于,气囊面料50由形成有排成一列的多个独立气囊510的气囊经线500与一般的纤维(天然、合成均包括)材料的纬线200编在一起来进行织造的织物制造。
其中,气囊经线500是指形成有排成一列的多个独立气囊510,在各气囊510内填充有按照用途选择的气体的呈薄又窄的带状的经线。
纬线200交替通过排列的多个这种气囊经线500的上下,并与气囊经线500相互编在一起,来形成气囊面料50。被织造的气囊面料50的织造方式为与纬线200编在一起的方式,即,根据在平织和斜织、繻子织方式中按照用途选择的方式可存在若干差异,并且,纬线200的宽幅可使用具有与气囊经线500的宽幅对应的大小的宽度的带,或将普通的细线使用作纬线200,使得实现更多种的织造方式。作为参照,图1中示出将细线作为纬线200,以编织方式织造的实施方式的气囊面料50。
如图1所示,在气囊经线500的气囊510之间可形成有捻合部520,这是根据本发明的生产方式所显示的结构,即,在向中空原丝内吹入气体时,一边对气囊510之间进行热熔敷,一边进行缠绕来完成气囊510的气密性。这种气囊经线500的生产方式具有如下优点,即使不使用以往的大面积的辊子或压力机,也可连续的低廉的生产大量的气囊经线500,对此将在后述的相应部分进行详细说明。
而且,优选地,填充在气囊510的气体的种类应按照气囊面料50的用途的选择具有适当性质的气体。例如,若只考虑一般水平的断热、缓冲效果,则填充无需额外费用的空气即可,若使用于消防服,则应当填充在高热环境中气囊510被破裂时,可冷却皮肤表面,并阻止火焰传播的二氧化碳。并且,若为使用于在水中所使用的救生衣的气囊面料50,则优选地,为使浮力增大,填充非可燃性(非活性)气体中最轻的氦。
气囊经线500需要由几乎没有通气性的材料制作,使得完全密封填充在气囊510内的气体。并且,需要使用具有不因外力而意外破裂的适当水平的物理性质的材料,上述物理性质为,例如,当厚度小于1mm时,伸长率为200~800%,拉伸强度为70~200kg/cm2
作为这种气囊经线500的材料可为选自橡胶、合成橡胶、耐油橡胶、耐热橡胶、丁基橡胶、聚硫橡胶、氯磺化聚乙烯橡胶、聚氨酯橡胶、丙烯橡胶、硅橡胶、氟橡胶、三元乙丙橡胶类或聚氨酯、丙烯、硅、聚乙烯、聚丙烯、聚氯乙烯、聚苯乙烯的合成树脂类中的至少一种。
其中,在本发明的气囊面料50使用于消防服的情况下,优选地,适用具有适当水平的耐热性,使得在大约100℃左右的温度环境下,气囊510因热量而破裂,来使被填充的气体流出后可成为冷却皮肤的材料。这种材料代表性的可举聚氨酯(PU),此外,也可适用聚乙烯(PE)、聚丙烯、聚氯乙烯、聚苯乙烯、聚氨酯等。
在本发明的实施方式中,考虑到穿戴感、断热性等各种功能,气囊510的厚度应介于0.5~2.0mm的范围内。与此相比,考虑到要填充的气体的量,气囊510的直径可在2~20mm左右的稍广的范围内进行调节。
而且,如图2所示,由气囊经线500与一般纤维材料的纬线200进行织造的气囊面料50的表面可分别衬上里料600和/或外料400。
里料600应使用如在大体上接触穿戴者的皮肤时,可感觉到舒适的穿戴感,或能够很好地吸收汗的可提高穿戴者的穿戴感的纤维。为实现这种目的,作为里料600,可使用如芳香族聚酰胺类纤维。
与此相比,外料400需要使用按照适用气囊面料50的衣服的种类来强化其固有功能的材料的纤维。例如,在消防服的情况下,作为外料400,可使用由聚苯并咪唑类耐火纤维进行织造的衣料,在救生衣的情况下,作为外料400,可使用对使用浮于水的纤维进行织造而成的浮力织物,上述浮于水的纤维包括比重大于水的芯纤维及在芯纤维的外层中含有90~99%以上的浮力剂的涂覆层。
另一方面,根据本发明的气囊面料50的一系列制造工序如图3所示,参照图3对其制造方法进行说明。其中,将省略与此前说明的对于气囊面料50的内容重复的结构。
如图3所示,本发明的气囊面料50的制造方法包括:准备多个独立气囊510排成一列并在各个上述气囊510内填充有气体的气囊经线500的步骤;以及以平织、斜织、繻子织中的一种织造形态来对上述气囊经线编织纬线200的步骤。
其中,气囊经线500能够以在制造中空的原丝的同时,一边向原丝内吹入适当的气体,一边对气囊510之间以热熔敷等的方法进行密封,来使气囊510排成一列的方式制造。
即,管TB的内侧以同心圆形状配置气体喷嘴NZ,一边通过气体喷嘴NZ喷射气体,一边向管内压送液态的橡胶类或合成树脂类的原丝材料,即可制造中空的原丝。
而且,使向管TB外排出的中空原丝卷绕在旋转的线轴BB,此时,通过利用熔敷单元HB对相邻的气囊510之间施加热量和压力来贴合,使得形成独立的多个气囊510,与此同时,使线轴BB在相对于中空原丝的长度方向的垂直面上进行旋转,来在相邻的气囊510之间形成捻合部520。如上所述,在中空原丝内吹入气体,且一边对气囊510之间进行热熔敷,一边赋予缠绕,可使气囊510的气密性更加完美。并且,若在气囊510之间形成有捻合部520,则气体聚在由原丝的缠绕而新制造的气囊510一侧,来使气囊510内填充有具有充分的压力的气体,使得制造球形或椭圆形形态的紧绷的气囊510,因此,产生使气囊面料50的缓冲功能、断热功能、冷却功能、浮力功能等的诸多性能提高的优点。
作为参照,图3为使气囊经线500的制造工序更容易理解,而仅示出在一个装置中,制造一个气囊经线500的结构,但需要注意的是,气囊经线500的制造工序也能够以在一个装置中,同时制造多个气囊经线500的方式构成。
第二实施例
如图4所示,根据本发明的第二实施例的具有形成有多个独立气囊的气片的面料包括:气片10,上述气片10包括多个气囊11及平板型塑料12,多个上述气囊11分别以球形或与球形类似的形态独立形成,具有优秀的伸长率,在内部填充有符合用途的气体,上述平板型塑料12附着在上述气囊11的上下部;以及形状维持框20,与上述气片10的外侧相结合。
上述气片10为沿着上下左右连续形成有多个气囊11的伸长率达到200~800%的弹性类材料。
伸长率在200~800%范围内的橡胶或合成树脂均相当于上述弹性类的气片10,这种气片10的材料可使用选自如橡胶、合成橡胶、耐油橡胶、耐热橡胶、丁基橡胶、聚硫橡胶、氯磺化聚乙烯、聚氨酯橡胶、丙烯橡胶、硅橡胶、氟橡胶、三元乙丙橡胶的橡胶类或如聚氨酯、丙烯、硅、聚乙烯、聚丙烯、聚氯乙烯、聚苯乙烯的合成树脂类,优选地,这种气片10所需要的物理性质,需要具有优秀的伸长率,且拉伸强度在70~200kg/cm2的范围内。
填充在上述气片10的气囊11内的气体,应符合用途,在使用于消防服的情况下,需要填充二氧化碳,在使用于救生衣的情况下,需要填充氦气。
本实施例中,在上述气片10中,连续形成有圆形的气囊,为了使穿戴感提高,平板型塑料12附着于上述气囊11的上下部。
在上述气片10上可选择性适用防燃处理。即,在气片10上进行防燃处理的情况下,即使在高温的火焰下也能防止面料的受损,从而具有保护穿戴其的使用者的身体的优点,另一方面,在气片上没有进行防燃处理的情况下,具有面料因高温的火焰而受损,从而使填充在气囊11内的气体漏到外部进行灭火的优点。
本发明的形状维持框20配置于构成气片10的平板型塑料12的外侧,在对相邻的多个气囊11之间的缓冲空间15内供给气体的情况下,作抑制平板型塑料12的过度膨胀的同时维持规定的形态的功能。
即,形状维持框20以平板形状为基础,通过冲压至压花工序向一方向形成多个半球形状的圆顶体。上述多个圆顶体可为分别配置于气囊11之间的结构。由此,如图5的(b)部分所示,在平板型塑料12向外侧扩张的情况下,借助上述形状维持框20的圆顶体防止过度膨胀。
其中,在多个气囊11之间的缓冲空间15上可填充与填充在气囊11内的气体相同的气体,或填充不同的气体。另一方面,如图5的(b)部分所示,多个气囊11及缓冲空间15上,由于分别填充第一气体G1、第二气体G2等不同的气体,可使互相缓冲作用最大化。
第三实施例
另一方面,如图6所示,根据本发明的第三实施例的具有形成有多个独立气囊的气片的面料包括:气片10,上述气片10包括多个气囊11及平板型塑料12,多个上述气囊11分别以球形或与球形类似的形态独立形成,具有优秀的伸长率,在内部填充有符合用途的气体,上述平板型塑料12附着在上述气囊11的上下部;里料30,附着于上述气片10的外侧,按照用途来使用;外料40;以及形状维持框20,与上述里料30和外料40的外侧相结合。
上述气片10为沿着上下左右连续形成有多个气囊11的伸长率达到200~800%的弹性类材料。
本发明的形状维持框20配置于包围气片10的里料30和外料40的外侧,在对向相邻的多个气囊11之间的缓冲空间15内供给气体的情况下,作抑制里料30和外料40的过度膨胀的同时维持规定的形态的功能。
即,形状维持框20以平板形状为基础,通过冲压至压花工序向一方向形成多个半球形状的圆顶体。上述多个圆顶体可为分别配置于多个气囊11之间的结构。由此,如图7的(b)部分所示,在里料30和外料40向外侧扩张的情况下,借助上述形状维持框20的圆顶体防止过度膨胀。
其中,在多个气囊11之间的缓冲空间15上可填充与填充在气囊11内的气体相同的气体,或填充不同的气体。另一方面,如图7的(b)部分所示,在多个气囊11及缓冲空间15上,由于分别填充第一气体G1、第二气体G2等不同的气体,可使互相缓冲作用最大化。
参照图8,向上述气片10的气囊11内填充气体的方式如下。
在封闭的空间300内形成有气囊成型槽301a的一对吸引辊子301之间,投入合体前的气片10。上述气片10在合体前的位置,在用于喷射气体的喷射喷嘴302喷射气体后,借助气囊成型槽301a以贴合气片10的方式填充气体。另一方面,填充气体的方式不局限于此,也可在封闭的空间通过沿着上下方向进行工作的压力机,将气体填充至气囊11内。
使用于上述气片10的内侧的里料30,优选地,需使穿戴者感觉到舒适的穿戴感,但在使用于消防服或救生衣的情况下,优选地,使用具有防水性的里料。
使用于上述气片10的外侧的外料10按照用途相异,在使用于消防服的情况下,使用由耐火纤维进行织造的外料,在使用于救生衣的情况下,可使用具有浮力的浮力纤维或一般的防水服。
参照图9,根据本发明的一实施例的具有形成有多个独立气囊的气片的面料包括:气片10,形成有多个气囊11,多个上述气囊分别以球形的形态独立形成,分别在其内部独立填充二氧化碳G1;芳香族聚酰胺类里料30,形成于气片10的内侧,质地柔软,具有良好的吸汗力;外料40,形成于气片10外侧,由聚苯并咪唑类耐火纤维进行织造而成。另一方面,在多个气囊11之间的缓冲空间15上,可填充与填充在气囊11内的气体不同的气体G2。
本实施例中,上述气片10由聚氨酯制造。上述聚氨酯为由醇基与异氰酸基的结合而制备的聚氨酯结合来结合的高分子化合物的总称。代表性的有以合成纤维制造的氨纶。聚氨酯类合成橡胶也广泛使用,聚氨酯类合成橡胶包括聚酯类和聚醚类,聚酯类使丙二醇和乙二醇与己二酸进行反应来制备聚酯,且将两端具有羟基的分子量3000为止的聚酯以萘-1,5-二异氰酸来进行聚氨酯化的同时制备成高分子,并且,在聚醚类中,在环氧丙烷烯混合一些环氧乙烷来首先制备为聚醚,将其两个末端的羟基与二苯乙烯二异氰酸进行反应,制备高分子量的聚氨酯。气片由这种具有优秀的拉伸强度、优秀的伸长率的聚氨酯制造,但并不局限于此,也可使用聚乙烯,聚乙烯通过将石油的原油分馏来分离石脑油部分(100~200℃流出部分),通过将其分解来分取约25%的乙烯,对该乙烯进行聚合来制备,根据这种聚合方法产生多种聚乙烯,低密度聚乙烯(软质聚乙烯)和高密度聚乙烯(硬质聚乙烯)为主要产品,优选地,为低密度聚乙烯,这种低密度聚乙烯将微量的空气作为催化剂,在1000atm,200℃以上的高压下,通过加热来制备,因此,一般称为高压聚乙烯,密度为0.91左右,因具有分支,分子的排列不够充分,由于结晶的部分为65%左右,质地松软,使得容易拉伸,虽然拉伸强度有点小,但耐冲击性大。
在本实施例中,为使用于消防服,以使用因耐热性弱,可在100℃温度下破裂的聚氨酯来说明,但不局限于此,当然也可使用作为热可塑性合成树脂的聚乙烯、聚丙烯、聚氯乙烯、聚苯乙烯及聚氨酯。这种热可塑性合成树脂为已公开的物质,由这种物质制造具有优秀的弹性复原力的上述气片是显而易见的。
在使用聚氨酯的情况下,使用软质聚氨酯,这种软质聚氨酯具有良好的气垫性及延伸率、优秀的拉伸强度及耐磨耗性的机械性刚度,因此可很好地使用。
本发明中,构成上述气片10的各气囊11的厚度可根据所使用的合成树脂变更,大约在0.05mm~0.9mm之间的范围内选择,各气囊11的直径可在2~15mm的范围内根据用途选择。即,在所需的拉伸强度大的情况下,优选地,直径能够以最大的大小形成,厚度也变厚。
本实施例中,构成上述气片10的多个各气囊11以厚度为0.2mm、大小为直径3mm的方式制造,这种大小仅为一个实施例,其厚度和大小可按照用途变更。
在本实施例中,在上述气囊11内填充有二氧化碳,这种二氧化碳作为气体状态的二氧化碳可用作冷却材料,因此,在制造如图10所示的消防服100时,在起火现场穿戴时,填充的二氧化碳会膨胀,若加热至规定温度以上时,则因聚氨酯在100℃温度下使用,在超过100℃时,各气囊11独立破裂,因此按照加热的部位逐渐破裂,使破裂的部分被冷却,使得可作为冷却材料来使用,在因一定程度的冲击或高温破裂的情况下,由于具有各自独立的空间,在破裂前被挤压的同时吸收冲击,带来充分的缓冲效果,在破裂时,排放二氧化碳,使得可作为冷却材料来很好地使用。
本实施例中,上述气片10的气囊11破裂前的载荷为600kgf/cm2,在破裂前由于气囊11收缩的同时吸收冲击,可确认具有充分的缓冲效果,这种气囊11在前后左右连续放置,因此可承受更大的500kgf/cm2以上的破裂载荷。
在本实施例中记述的是,芳香族聚酰胺类里料30作为上述里料来使用,但使用包括压薄面料的植物材料也无妨。
在本实施例中,在上述气片10的内侧附着有芳香族聚酰胺类里料30,来在接触穿戴者的身体时,使穿戴者感觉舒适的穿戴感,由于在上述气片10的外侧附着有由聚苯并咪唑类耐火纤维进行织造的外料40,对热量具有大的耐久性的同时,可从火气保护穿戴者。
如图10所示,在本发明的另一实施例中,对使用于救生衣的具有形成有多个独立气囊的气片的面料进行说明。具有形成有多个独立气囊的气片的面料包括:气片10,形成有多个气囊11,多个上述气囊11分别以球形的形态独立形成,分别在其内部独立填充氦气G3;芳香族聚酰胺类里料30,形成于气片10的内侧,质地柔软,具有良好的吸汗力;外料40,形成于气片10的外侧,使用对浮于水的的纤维进行织造来制造的浮力织物,上述浮于水的纤维包括比重大于水的芯纤维和在芯纤维的外层含有90~99%以上的浮力剂的涂覆层。在本实施例中,上述气片10使用耐油橡胶,来阻断水分的流入。
上述以浮力织物构成的外料40,包括在具有比重大于水的芯纤维的外层中含有90~99%以上的浮力剂的涂覆层,由于上述浮力剂为油系统,具有与具有大极性的水几乎没有亲和力的亲油性,由此在外层涂敷有上述浮力剂的纤维由于水不能渗透到纤维内部,纤维内部的空气层不会因水而消失,使得可具有最大化的浮力。但是,可以不使用这种以浮力织物构成的外料40,也可将一般的方防水织物或用于一般的外皮的织物作为外料40来使用。
并且,根据本发明的面料制造的救生衣100,其袖子101或裤子下端102借助橡胶带等的弹性部件以密封的方式形成,因此即使在水中长时间漂浮,水分也不会向救生衣100内流入,由于借助气片10的气囊11处于与外气阻断的状态,可防止体温被水分抢走导致的因低体温症而死亡的危险。
如上所述,根据本发明的具有形成有多个独立气囊的气片的面料包括:气片,形成有多个气囊,上述气囊分别以球形或与球形类似的形态独立形成,分别在其内部独立填充二氧化碳或氦气;芳香族聚酰胺类里料,形成于气片的内侧,质地柔软,具有良好的吸汗力;外料,形成于气片地外侧,由防火织物、浮力织物或一般的防水织物构成,通过在内部设置形成有分别以球形或与此类似的形态独立形成且分别在其内部独立填充二氧化碳或氦气的多个气囊的气片,来使各个气囊独立维持,并在镇压火灾时,在适当的环境下独立破裂,来保障消防员的安全,并增进使用的便利性,使效力持续的长久,在海上落难时,由于与外气隔断,使得可以维持体温,从而可很好地使用于救生衣。
本发明的技术问题通过如上所述的技术结构实现,虽然本发明仅通过限定的实施例和附图进行了说明,但本发明并不局限于此,本发明所属技术领域的普通技术人员可在本发明的技术思想和发明要求保护范围的同等范围内极其容易地进行多种修改及变形。
