Description
本发明涉及一种用于生产鞋的层压产品,并涉及生产鞋内底的方法。
在鞋类生产中,通过针刺工艺将不同材料的两层联结在一起以生产出不同种类的层压产品,这已是众所周知。然而,这些产品存在一个缺陷:它们通常不能为最终产品提供良好的刚性,因此它们只限于用在不需要良好刚性的产品中。故它们并不非常适合作为鞋的内底。
本发明的一个目的是提供一种用于鞋生产的层压产品,它能克服上述缺陷。更具体地说,本发明的目的是提供一种层压产品,它适合于在鞋生产中使用,它包括:
由弹性泡沫材料制成的一上层;以及
由纤维垫制成的一底层,它包括:
多种纤维,其中一部分刺穿上层泡沫材料把底层联结到上层;以及
一刚性部分为产品提供刚性。
本发明的另一目的是提供一种用于鞋生产的层压内底,它包括:
由弹性泡沫材料制成的一上层,其轮廓形状使之可以放置在鞋中;以及
由纤维垫制成的一底层,其形状与上层外形一致,该纤维垫包括:
多种纤维,其中一部分刺穿上层泡沫材料将底层联结到上层;以及
一刚性部分为鞋内底提供刚性。
上层最好有一外表面与底层相对,所有刺穿泡沫材料的纤维都从所说外表面露出,从而在该表面上提供了一层毛茸。
并且最好通过用一种材料浸渍纤维垫的外表面来获得底层的刚性部分,所述材料是从胶乳、热塑性树脂溶液以及热固性树脂溶液中选用的。
另外,纤维垫也可以包括多种结构纤维和多种联结纤维,其中结构纤维具有给定的熔点而联结纤维的熔点低于结构纤维的熔点;然后通过将纤维垫的一外表面置于高于联结纤维的熔点而低于结构纤维的熔点的温度下,从而使纤维垫获得刚性部分。
本发明的进一步的目的是提供一种适于鞋生产的层压产品的加工方法,该方法包括以下几个步骤:
a)把包括多种纤维的纤维垫层针刺到由弹性泡沫材料制成的一层,这样使一部分说纤维刺穿泡沫材料;以及
b)加强纤维垫的一部分为鞋内底提供刚度。
根据本发明的层压产品,其优点是,适合于任何鞋的内底以及插入鞋垫。可以理解,它利用了泡沫的弹性和纤维垫的刚性及热成形性能,以一种优选的型式,它还利用了覆盖着泡沫上层的毛茸所提供的舒适性。
下面参照附图,对优选实施例进行非限制性描述。
图1是根据本发明一个优选实施例的鞋内底的俯视图;
图2是图1所示鞋内底的一个垂直横截面侧视图;
图3是根据本发明的层压产品的垂直横截面侧视图,示出在针刺步骤前的情况;
图4是图3的同一视图,示出在针刺步骤后的产品;
图5是同图4相同的视图,示出针刺到泡沫上层的一织物层;以及
图6是与图5相同的视图,示出用一种树脂浸渍纤维层后的产品。
现在参照图1,2和6,本发明的一般特征是适于用作鞋内底的一种层压产品(2),它也可用作插入鞋垫。该产品可以作成平的并切割以配合脚的形状。它包括由弹性泡沫材料(4)制成的上层,以及如果它被用作如图1所示的鞋内底的话,还包括其形状适于放在鞋中的轮廓(6)。产品(2)进一步包括由纤维垫(10)制成的底层,其形状与上层(4)的轮廓一致。包括多种纤维(12)的纤维垫(10)被针刺到上层(4),这样一部分纤维(12)穿过上层(4)的泡沫材料从而把底层(10)联结到上层(4)。纤维垫(10)进一步包括一刚性部分(14)为产品(2)提供刚度。如图所示,纤维垫(10)最好包括无纺纤维垫。
所有穿过泡沫材料(4)的一部分纤维(12)的每根最好从上层(4)的外表面(16)露出来,从而在该外表面上提供了毛茸(17),使产品(2)具有舒适的性能。
另外,层压鞋内底(2)还可包括一埋置于纤维垫(10)中的加强层(9)。换言之,纤维垫(10)的结构中可包含一种加强织物或加强层(9),在纤维垫(10)的制造过程中与纤维联结在一起。
加强织物或加强层(9)可以是带有微小开孔的聚丙烯稀松织物,或者所说的稀松织物的一侧或两侧涂敷1到3密耳的聚丙烯覆盖层,其它覆盖层,稀松织物或者薄膜可从聚酯、尼龙、聚乙稀中选择,只要它们能承受压层生产过程中或鞋产品的生产过程中产生的温度,就可以使用。
一附加纺织层(18)也可联结在泡沫上层(4)。在图2所示的实施例中,底层(10)纤维(12)穿透上层(4),把所说附加纺织层(18)联结到上层(4)表面上。在另一优选实施例(未示出)中,该附加层也可层压到顶层表面。该附加层(18)可包括另一非织造垫、毛毡、针织物、起绒布、合成羊毛或其它能提高产品舒适性或美观性的纺织品。
可以理解,图1,2和6所示本发明的型式利用了合成泡沫的弹性、纤维垫的刚性和热成形性能,以及刺穿泡沫的纤维所提供的舒适性。
这些性能是通过提供具有刚性的底层(10),弹性合成泡沫(4)的上层以及手感舒适的上表面来获得的。
纤维垫(10)最好包括从下面一组中选出的多种纤维(12),这组纤维是由合成纤维如聚酯、聚丙烯、尼龙等;或者人造纤维如人造纤维素纤维、粘胶纤维等;或者天然纤维如羊毛、黄麻等;以及它们的混合物组成。纤维垫(10)也可包括具有特殊作用的纤维。例如,如果通过针刺工艺传送的纤维是导电的,那么生产的产品将能散逸静电。比较有利的情况是,底层(10)可包括少量导电纤维,最好重量占1%到20%。这些纤维的阻抗低于10-3Ωcm,可由不锈钢、铜或者包覆了一层镍、银或其它导电金属的合成纤维制成。也可使用碳纤维、埃比特罗比克纤维或包覆碳的纤维、或者聚合导电纤维。例如,纤维垫(10)可包括3-6%的为德国STATEX生产的商标为EX-STAT的包覆镍的丙烯腈纤维。
底层(10)还可包括包含防止真菌或细菌生长的试剂。这些纤维将防止细菌在脚下生长,并最好从一组包括聚酯,聚丙烯,醋酯丙烯腈纤维或类似纤维中选择。例如由HOECHST公司生产的命名为MICROSAFE的2分特醋酸纤维是适合的。
而且,这些纤维(12)最好是耐热的。
纤维垫(10)的精确构成依赖于硬化其结构的工艺和多层产品的期望用途。
纤维垫(10)的纤维(12)的尺寸优选在0.7和25分特之间,更优选在1.5和10分特之间。其长度优选在25到150mm之间,更优选在38至100mm之间。底层(10)通过传统的梳理工艺,然后针刺所选纤维的混合物来制成。底层(10)的表面密度优选在70到1000g/m2之间,更优选在200到800g/m2。
上层(4)的弹性泡沫材料可以是开孔或封闭腔的聚合泡沫。它最好包括从以下一组材料中选出的一种聚合物,这组材料包括聚氨酯、聚酯、聚醚、交联聚丙烯、聚氯乙烯、以及类似材料。这种泡沫有市售商品。例如,一种开口腔的聚氨酯泡沫,比如由RODGERS公司生产的商标为PORON的材料。
在第一个优选实施例中,通过用一种材料浸渍纤维垫(10)的外表面(20)而使底层(10)获得刚性部分(14),这种材料是从一组包括胶乳,热塑性树脂和热固性树脂溶液中选出的。然后该胶乳或溶液经烘干而交联。这种操作为鞋内底提供了所需刚度。
最好在使纤维垫(10)保持用于减震的良好弹性的同时使其具有刚性。树酯是从以下一组材料中选出的,该组材料包括:聚丙烯腈、甲基丙烯酸甲酯、醋酸乙基乙烯酯、聚乙烯醇、苯乙烯丁二烯树脂以及包括三聚氰胺甲醛的苯乙烯丁二烯树脂。
在干态下,所需树脂量的变化范围在100到350g/m2之间,最好是150到250g/m2。
在第二个优选的实施例中,可通过混合结构纤维与联结纤维使纤维垫(10)具有刚性,更具体地说,在此情况下,纤维垫(10)包括多种具有给定熔点的结构纤维以及许多熔点低于结构纤维熔点的联结纤维。通过使纤维垫(10)的外表面(20)加热到大于联结纤维熔点而小于结构纤维熔点的温度而获得其刚性部分(14)。通过加热纤维垫(10),使其温度恰好超过联结纤维的熔点,则可获得所需刚度。最好是,只有纤维垫(10)被加热,而上部结构保持在室温。这样就保持了足够的泡沫。
纤维垫(10)中联结纤维的重量比优选在10%到80%,更优选从25%到60%。这些联结纤维最好从下面一组纤维材料中选出,该组纤维包括具有较低软化温度的聚酯、或者共聚酯、高密度或低密度聚乙烯、聚丙烯、或者皮芯型或并列型双组分纤维。对于皮芯型双组分纤维,纤维芯具有较高熔点,而外套纤维由低熔点聚合物组成。在加热过程中,外套将保持纤维间的交联。
参照图3到图6,其中示出了制造一种层压产品的方法的一种优选型式的连续步骤,该层压产品适合于鞋类生产。该方法包括以下几个步骤:a)将包括多种纤维(12)的纤维垫(10)层针刺到弹性泡沫材料(4)制成的一层上,这样一部分所说纤维(12)刺穿了泡沫材料(4)。图3示出了针刺步骤之前的纤维垫(10)和泡沫层(4);图4示出了针刺步骤后的相同层。最好如图5所示,在步骤a)中,穿透泡沫材料(4)的一部分纤维(12)还可用于结合一纺织附加层(18),如前所述。附加层(18)也可以传统的层压方法层压到该产品上。所述方法进一步包括步骤b),硬化纤维垫的一部分使鞋内底具有刚性,如图6所示,然后是步骤c),如果该产品将被用作鞋内底,并具有与鞋一致的轮廓形状的话。
如前所述,所用纤维垫(10)和泡沫材料(4)最好是前面所述的纤维垫和泡沫材料。
优选地,在通过本发明所述方法硬化压层底部之后,另外一压延步骤可有助于致密由加强织物(9)加强的纤维垫(10),从而获得小于每分钟5立方英尺的Frazier透气性。这种层压产品非常适合于通过把热塑性塑料、橡胶、聚氨酯、或聚氯乙烯鞋底直接注塑在本发明所述的鞋底上制成鞋。
可以理解,该方法包括通过倒钩将底层(10)的一部分纤维(12)传送穿过上层(4)。传送纤维(12)的量可通过控制每平方厘米的穿针数和针刺进入泡沫材料(4)的深度来调节。
穿透的纤维最好从上层(4)的外表面(16)露出来,从而使这些纤维在上层(4)表面上是可见的并且形成毛茸(17)。
上层(4)表面上的毛茸(17)为产品提供了舒适性。它还有利于汗和水汽的排散。此外,穿透上层(4)的纤维(12)改善了汗和水汽从脚向底层(10)的传送,汗和水汽在底层(10)散逸。如果伸到上层(4)外表面(16)的纤维(12)是导电纤维或防止细菌生长的纤维,上层(4)表面上的这些纤维允许散逸静电,在鞋内底和脚之间提供一种连结,或者防止由于细菌生长产生的臭气。
硬化步骤b)最好包括下面几步:
-把纤维垫(10)部分浸渍在从胶乳、热塑性树脂和热固性树脂溶液组成的一组材料中选出的一种材料中;
-将纤维垫(10)加热到100℃到200℃之间,优选在130到180℃之间保持一段时间,以便分散溶剂挥发并使树脂网组化;以及
-冷却纤维垫(10)
图6示出通过用胶乳或合成树脂溶液部分涂敷纤维垫(10)使其硬化后的层压产品(2)。事先传递入泡沫材料的扩散通过刮擦或其它工艺被推进到非织造垫(10),在非织造垫(10)中产生预定深度的渗透。然后纤维垫(10)加热到100到200℃的温度,最好在130到180℃,保持一段时间使扩散溶剂挥发,并使树脂网组化。在冷却后,获得的刚性通过测量所述结构的耐弯曲性来控制。最好如图6所示的实施例,上层(4)由聚氨酯制成的泡沫在此工艺中不会被破坏。
纤维垫(10)优选由纤维垫总量的100g/m2到350g/m2的树脂,更优选为150到250g/m2的树脂浸渍。
另外,步骤b)的固化可通过不使用扩散形式粘合剂的工艺来完成。在此情况下,如前所述,纤维垫(10)包括多种具有给定熔点的结构纤维和多种熔点低于结构纤维熔点的联结纤维,其中硬化步骤b)包括以下几个步骤:
-使纤维垫(10)的外表面(20)在给定时间内承受大于联结纤维的熔点而小于结构纤维熔点的温度;并且
-冷却纤维垫(10)。
对于其它优选的实施例,纤维垫(10)还可包括导电纤维或防止细菌生长的纤维。该实施例最好通过包括两个连续带的系统将热传导到纤维垫(10)而使其硬化。其中一条带被加热到足以使联结纤维软化的温度。另一条带保持在室温,并保持与该结构宽度相等或稍小的距离。该结构必须保持在软化温度足够长的时间,以便热量穿透纤维垫(10)的宽度而不会加热或软化上层(4)。也可使用其它加热技术来加热纤维垫(10),例如,幅射、对流或传导技术。
根据本发明的一种层压产品(2)在以后可热成形为所需形状,如图6所示。
尽管本发明的优选实施例在此已有详细描述,并在附图中示出,但是应该理解;本发明并不限于这些精确的实施例,在不脱离本发明范围和宗旨的前提下可以对其进行各种变化和改进。
