针对弹性绵纱作进一步分析，其结构以若干纱线以相互纠结卷曲方式所形成，其纱线于多数结合使整个垫体因而具有支撑性，配合各该纱线间具有缝隙空间，而达到自动恢复的缓冲效果；而此类弹性棉纱相较于其他弹性材质，其具有较佳的散扫性及透气性，且恢复弹性较为灵敏等特性，使用时可依结构所需作裁切，于组装及使用上的操作也相当简便，又可广泛应用于各领域中。
现有的弹性绵纱的制造流程，如国内第083101192号发明专利所揭露的缓冲垫用网状构造体及制法，其制造过程起始原料主要使用热塑性弹性树脂，自数个细孔，于比融点高10℃-80℃的温度下，将融态热塑性弹性树脂向下方射出，于融态形成连续线状体的毛圈，个别毛圈互相接触，融合成三次元无规则毛圈构造，同时以拉伸装置夹持，接续加以冷却，一旦冷却后，在比融点至少低10℃以上的温度，进行退火者，其中连续线状体的纤度在300-100000丹尼者，无规则毛圈的直径为2-50mm，且网状构造体的表观密度为0.005-0.1g/cm。
另有一种弹性绵纱的制法，如国内第090126977号发明专利所揭露的制造透气弹性垫的方法，制法流程包括：a：进料熔融：将具有弹性特性的塑胶原料备好，并加热熔融；b：吹气成型：塑料经吹气成型而形成中空管状的塑性条；c：滚制成型：塑性条送出吹气嘴之处加设至少有一的辅助加热器，塑性条送到两互为相邻、且等速相对转动的导轮与调整轮之间，调整轮与导轮一部份浸入到冷却槽内，让塑性条在导轮上呈卷曲状成形，由调整轮压触成形的塑性条以控制厚度；d：冷却：塑性条进入冷却槽前，各塑性条在数点因相互熔接合，使该接合点形成连接处，进入冷却槽即冷却固化，使各塑性条形成不规则交错的透气孔；e：裁切：将成型、互相连结而呈长形塑性条，经输送出导轮以后，便依设定规格，一一裁切形成一块块弹性垫。
也有一种弹性绵纱的工艺及结构，如美国第US7,993,794号发明专利所揭露的三维网状结构，及生产该三维网状结构的方法和设备，以预备的热塑性树脂原料所制造，其中该树脂形成多个螺旋和随机纠缠，以挤出成型的部分热粘合细丝，于该丝液体冷却从而获得网状结构，其中该网状结构有单个或多个高密度地区在沿着一条边或平行边的网状结构，网状结构的厚度方向排列。
上述工艺中，虽同为弹性绵纱的制造技术，且其成品均呈卷曲纠结状态的纱线所构成；但是，细察前述工艺仍分别属于针对不同结构的弹性绵垫，所应用的不同制造技术，其中第一案为制作单一线径尺寸、单一原料、且呈同密度的弹性网体结构；第二案则为制造中空线纱、单一线径尺寸、单一原料、且呈同密度的弹性网体结构；第三案则为单一线径尺寸、单一原料、呈不同密度的弹性网体结构。
 技术问题
前述现有的工艺中，均未针对同时具有不同线径尺寸及不同密度，甚至同时使用不同原料的弹性绵纱作揭露，目前现有技术也未能达到同时押制出二层以上，分别具有不同线径尺寸及不同密度的弹性网体结构；故本发明人针对此类弹性绵纱的工艺，提供可一贯作业完成以同步形成多层、且多重线材的立体弹性垫工艺。
 技术解决方案
有鉴于此，本发明所揭露多重线材的立体弹性垫工艺，包含有下述步骤：

 本发明的最佳实施方式
首先请参照图1至图5所示，本发明所提供的一种多重线材的立体弹性垫工艺，主要包含有下列步骤：
(a)熔融一塑性原料于二射出口（12、13）出料：
将一塑性原料于一融炉10内熔融，其具有倒入该塑性原料的一入料口11，及该融炉10的预设部位设有二射出口（12、13）分别进行出料；该塑性原料可为聚烯烃共聚物PEO、聚烯烃及橡胶共聚物PET、尼龙系弹性体Nylon、及聚氨基甲酸酯弹性体PU等等材料的运用。
(b)押制二种线径的线纱(31、32)成型：
利用一押制纺模20与各该射出口(12、13)接设，该押制纺模20具有第一线体押制区21和第二线体押制区22 、以分别对应各该射出口(12、13)，各该第一线体押制区21和第二线体押制区22分别设有布满的若干纱线押孔(211、221)，其各自具有不同孔径大小及不同孔径设置密度，以使各该射出口(12、13)进入的塑性原料于分别经过各该第一线体押制区21和第二线体押制区22后分别押出线径及密度不同的二种线纱(31、32)成型。
(c)厚度调整：
以设置于一水槽40的水面下的一厚度调整装置50衔接该押制纺模20所押出的各该线纱(31、32)，并利用一厚度调整模51将各该线纱(31、32)集中并共同压缩形成预设的厚度尺寸；该厚度调整模51呈两相对应的左右模具，以相对线性位移的方式，调整各该线纱(31、32)的整体宽度。
(d)纠结各该线体(31、32)成型：
各该线纱(31、32)经该厚度调整装置50及进入该水槽其冷却水作用后则开始相互纠结，以形成具有连续状且呈二层各该线纱的一立体弹性纱30。
(e)导引及裁切出料：
利用一导引装置60将该立体弹性纱30以预设速度导引出水面，并以一裁切装置70与该导引装置60相接，将连续导引延伸的该立体弹性纱30裁切形成预设形状及尺寸，完成具有二层不同线径及不同密度的各该线纱所形成的一立体弹性垫80。
借助上述流程，以生产线一贯作业同步完成具有多层、且多重线材的立体弹性垫工艺，该押制纱模20所押制形成至少二层以上不同孔径及不同密度的立体弹性纱结构，同时达到支撑力高及缓冲性佳的双重效果，配合该厚度调整装置50具有厚度调整功效，使裁切前该立体弹性纱30即已符合预设厚度，亦可依需求形成预设的线纱(31、32)层数或变换各层线纱材质者。
为供进一步了解本发明构造特征、运用技术手段及所预期达成的功效，兹将本发明使用方式加以叙述如下：
本发明以前述五个流程依序进行，以一生产线的一贯作业制造该立体弹性垫80，首先于(a)步骤利用该融炉10分设二设出口(12、13)进行出料；然后于(b)则配合该押制纺模20的设置，并于其上分设有各该第一线体押制区21和第二线体押制区22以分别对应各该射出口(12、13)，利用各该第一线体押制区21和第二线体押制区22分别具有不同孔径大小及不同密度的若干纱线押孔(211、221)设置分布，而使各该纱线押孔(211、221)分别押制出预设线径及密集度的各该线纱(31、32)；接着于步骤(c)中利用设置于该水槽40内的该厚度调整装置50衔接并集中押制出的各该纱线(31、32)，进而限制各该纱线(31、32)可卷曲纠结的空间，即指可形成的预设厚度；再由步骤(d)于水槽40内受空间限制的各该纱线(31、32)即因温度降低，而相互开始卷曲纠结成型，以形成具有预设厚度并连续延伸的一立体弹性纱30；最后于步骤(e)以该导引装置60将纠结成型后的该立体弹性纱30推送导引至该裁切装置70，依需求进行长宽大小裁切，即完成一立体弹性垫80。
本发明的该押制纺模20具有第一线体押制区和第二线体押制区(21、22)，其差异在于各该第一线体押制区21和第二线体押制区22各别具有不同押制孔径尺寸的各该纱线押孔(211、221)，及各该纱线押孔(211、221)间的距离尺寸也不同；进一步说明者，该第一线体压制区21的该纱线押孔211孔径尺寸数值范围为0.5-3.0mm，其孔径距离较大，即密度较低，其尺寸数值范围为10-50mm；该第二线体押制区22具有该纱线押孔221孔径尺寸数值范围为0.1-1.0mm，同时其孔径距离较小，即密度较高，其尺寸数值范围为10-20mm；各该第一线体押制区21和第二线体押制区22两侧区隔的各该纱线押孔(211、221)孔径距离尺寸数值范围为1-50mm。
本发明该押制纺模20至该水槽40水面的距离尺寸(d)数值为100-1000mm；该导引装置60以定速导引该立体弹性纱(30)由该厚度调整装置50拉引至该裁切装置70，其导引速度的数值范围为0.1-3 m/min。
请参照图5，本发明该立体弹性垫80具有一支撑层81及一弹性层82，其中该支撑层81为线径尺寸较大且密度较低的线纱32所共同纠结组成，其线纱32纠结密度数值范围约为15-100 kg/m3，丹尼数1500-80000D；该弹性层82为线径尺寸较小且密度较高的线纱31所共同纠结组成，其线纱32纠结密度数值范围约为5-90 kg/m3，丹尼数60-10000D。本发明所述的密度以产品的质量与测量外观体积的比值计算方式，其体积包含各该线纱(31、32)纠结的空隙。
本发明利用该押制纺模20，其分设有不同孔径大小及孔径密度的至少第一线体押制区21和第二线体押制区22，其各别设有预设孔径及密度相异的各该纱线押孔(211、221)，故于分别衔接各该射出口(12、13)的进料后，各该第一线体押制区21和第二线体押制区22即分别押制形成至少二层以上不同孔径及密度的立体弹性纱30结构，解决现有工艺仅能押制出相同孔径或相同密度的问题。
本发明利用该厚度调整装置50，其具有厚度调整功效，以将押制出的各该线纱(31、32)于各该厚度调整模51两者间的预设空间内集中并纠结成型，以形成预设厚度的立体弹性纱30结构，可节省后续进行厚度裁切的作业，以达到降低制造成本的效果。
本发明的工艺所制造出来的该立体弹性垫80，为具有至少二层不同线径及不同密度的支撑层81及弹性层82结构，使其同时分别具有高支撑部位及高弹性缓冲部位于一身的弹性垫结构，相较于现有的仅单一层且单一线径的弹性网结构，本发明该立体弹性垫80因两侧硬度不同，而可同时达到支撑力高及缓冲性佳的双重效果，使用者可依所需翻转使用该立体弹性垫80即可，故使用上极为便利，亦即具高实用性。
请参照图6至图8，为本发明另一实施例，其立体弹性垫工艺，主要包含有下列步骤：
(a)熔融至少二种塑性原料分别于至少一射出口(12、13)出料：
将至少二塑性原料分别于一融炉10内熔融，并各别由各该融炉10的至少一射出口(12、13)进行出料。
(b)押制至少二种塑性原料及二种线径的线纱成型：
利用一押制纺模20与各该射出口(12、13)接设，该押制纺模20具有第一线体押制区21和第二线体押制区22以分别对应各该射出口(12、13)，各该第一线体押制区21和第二线体押制区22分别具不同孔径大小及不同孔径设置密度的若干纱线押孔(211、221)，以使各该射出口(12、13)进入的塑性原料于分别经过该第一线体压制区21和第二线体押制区22 、后，各别押出线径及密度不同的至少二种线纱(31、32)成型。
(c)厚度调整：
以设置于水槽40的水面下的一厚度调整装置50衔接该押制纺模20所押出的各该线纱(31、32)，并利用该厚度调整模具51将各该线纱(31、32)集中并共同压缩形成预设的厚度尺寸。
(d)纠结各该线体成型：
各该线纱(31、32)经该厚度调整装置50及冷却水作用后则开始相互纠结，以形成具有连续状的至少二层立体弹性纱30。
(e)导引及裁切出料：
利用一导引装置60将该立体弹性纱30以预设速度导引出水面，并以一裁切装置70与该导引装置60相接，将连续导引延伸的该立体弹性纱30裁切形成预设形状及尺寸，即完成具有至少二层不同塑性材料、不同线径、及不同密度线纱所形成的一立体弹性垫80。
此一实施例，主要利用至少二融炉10将二种不同的原料熔融，并使不同原料由各自的该射出口(12、13)进行进料，不同原料的各该射出口(12、13)也分别对应该第一线体压制区21和第二线体押制区22，则会押制出除了不同线径及密度外，且不同线纱材料的各该线纱(31、32)后，再依与较佳实施例完全相同的步骤(c)至步骤(e)完成工艺；所制造的该立体弹性垫80，其各该支撑层81及弹性层82分别为不同材质应用，且具有不同线径及不同密度押制出的各该线纱(31、32)，再进行纠结成型，因此，本实施例的该立体弹性垫80还具有不同原料的特性，同时达到原料搭配其特性应用变换的功效，及具有应用上的丰富性，为极具实用的工艺。其他制造方法、机具及模具使用方式、环境参数设定、及预期达到的功效，均与前述实施例相同。
请参照图9至图11，为本发明的再一实施例，其属三层立体弹性垫的制造流程为其实施态样，其中该融炉10设有三射出口(12、13、14)以对应第一线体压制区21、第二线体押制区22和第三线体押制区23 (、、，且该第一线体压制区21、第二线体押制区22和第三线体押制区23分别具有不同孔径及不同密度分布的各该纱线押孔(211、221、231)。
于制造时，第一线体压制区21、第二线体押制区22和第三线体押制区23分别押制出不同线径及不同密度的各该线纱(31、32、33)后，再依与较佳实施例完全相同的步骤(c)至步骤(e)完成工艺；所制造的该立体弹性垫80，其具有支撑性及硬度各自不同的一支撑层81、一弹性层82、及一中间层83，各层分别具有不同线径及不同密度的线纱所组成；故本发明的工艺可依需求一贯作业制作出多重层次、且各层分别具有不同支撑性及硬度的立体弹性垫，相较于现有的工艺及其弹性垫结构，本发明于使用上较具变化，于应用上较为广泛，可因应不同领域、不同产品、不同缓冲条件的需求。
请参照图12至图13，本发明的更一实施例，为交错状不同线径及密度的至少二线纱的实施态样，其中于步骤b的押制至少二种线径(31、32)的线纱成型，各该射出口(12、13)以适当数量并预设位置排列后，与该押制纺模20相接设，配合该押制纺模20上与各该射出口(12、13)相对应不同线径的纱线押孔(211、221)，即可押出相互交错状且线径不同的至少二种线纱(31、32)成型，相同的该线纱(31、32)间距亦均不同因而产生不同密度，而具有另一种不同弹性及支撑性的弹性垫。其他使用方式及预期功效，均与前述实施例完全相同。
综合上述，本发明所揭露的多重线材的立体弹性垫工艺，提供一种以一生产线一贯作业工艺，其所形成多层以上，且各层分别具有不同线径、不同密度以达到不同支撑效果的立体弹性垫，利用各该射出口，对应不同押制孔径及密度的各该线体押制区，而同时押制出不同线径及不同密度的各该线纱，再经由厚度调整、纠结成型、及导引裁切等流程，所制造的该立体弹性垫，其具有分属不同支撑性及硬度的多层弹性层，各层的纱线分别具有不同线径及密度，又可依需求形成预设的线纱层数或变换各层线纱材质，即能有效降低制造成本，且原料使用多元而使该立体弹性垫极富有使用变化性，可广泛应用于各产业，以因应各领域产品的不同需求，而获致一实用性高的多重线材的弹性垫工艺，使整体确具产业实用性及成本效益。
以上所述乃是本发明的具体实施例及所运用的技术原理，若依本发明的构想所作的改变，其所产生的功能作用仍未超出说明书及附图所涵盖的精神时，均应在本发明的范围内。
