Description

具有高厚度和弹性的针刺带
技术领域
本发明一般性地涉及纺织品的生产。更具体地,本发明涉及一种用于后处理或预缩针织织物的纺织机器用带。
背景技术
一般地,这种类型的机器用织物或带用于纺织品的制造中。更具体地,与本发明类似的一类纺织机器用带被用作所谓的预缩带。预缩带用在特殊机器(预缩机)上以使诸如针织织物的材料防缩。经过了预缩机处理的材料实际上在第一次洗涤过程中保持防缩。该工艺通常用于服装生产。
织物预缩机上使用的标准带通常较厚,厚度在16mm到22mm之间。通常利用聚酰胺、聚酯和芳族聚酰胺纤维来制造预缩机用带。当用在这类机器上时,所述带必须经历若干成圈工艺(loopingprocess),包绕若干通常具有不同直径的辊或筒。当所述带穿过机器时,其内表面和外表面在辊之间转换。
图1描述了典型的织物预缩机。具有内侧机器面4和外侧产品面6并沿图中箭头方向行进的预缩带2首先包绕驱动辊8。在驱动辊8处,将待预缩的织物或布10引入预缩机中并与预缩带2的外表面6接触。此刻由预缩带2运送的布10变成预缩带2和蒸汽加热筒12之间的夹层11。在预缩带2和蒸汽加热筒12之间压缩布10与用蒸汽加热布的共同作用产生例如尺寸稳定并且防缩的针织织物材料布。
但是,预缩带的厚度存在问题。当带2包绕驱动辊8时,其内侧机器面4被压缩并且缩短,而其外侧产品面8被拉伸并且伸长。当带2的弯曲在蒸汽加热筒12处反转时,外侧产品面6此时被压缩并且缩短,而内侧机器面4被拉伸并且伸长。图1中的方形13和梯形15描述这种带的相反面的交替压缩和拉伸。
由于带2的拉伸和压缩,外侧产品侧的表面6可能失去其一致性或光滑度。结果,外侧产品侧的表面6变得不规则,导致在加工布面上的印痕问题。此外,所述带中可能出现裂纹,从而限制带的使用寿命。已经证实,不仅预缩带包绕筒或辊的运动缩短使用寿命,而且对所述带的其它影响,例如从所加工的材料中引入到带上的酸性染料或漂白剂的残留,也缩短使用寿命。
已经尝试解决与现有的带相关的上述问题。例如,美国专利6,479,414(“’414专利”)公开了一种由基底织物、带层、弹性针织织物和最上层构成的纺织机器用带。如所公开的,弹性针织织物是针织套形式的经向针织品或圆筒针织品。机器用带的弹性来自弹性针织织物的物理结构,这是因为某些针织品的内在特性便是它们的弹性。也就是说,针织品的结构允许其在不影响制品完整性的条件下膨胀和收缩(拉伸和压缩)。
本发明的带与’414专利的带的不同之处在于本发明的带的弹性基布层是用弹性纤维平织的(flat woven),而不是用无弹性纤维针织的。因此,本发明的带的弹性源自平织弹性基布层中弹性纤维的使用。因此,本发明的带能够利用各种纺织方法生产,而不是如同’414专利那样仅限于经向针织或圆筒针织技术。而且,本发明的带的结构与’414专利的结构的不同之处在于本发明的带的外侧产品侧和内侧机器侧由针刺到基布层中的絮纤维构成。’414专利的带提到其间置有针织层3的“缝合”毡层2和纤维层4。但是,弹性还是由结构即针织产生的,而不是由弹性材料本身产生。
因此,需要一种带,其能够承受其表面的交替和反复的拉伸和压缩,使得其外侧机器侧表面不会变得不规则,而导致在其上加工的织物布料的印痕。而且,需要一种能够利用各种纺织方法制造的带。本发明旨在克服与现有技术的带相关的缺点。
发明内容
因此,本发明的主要目的是提供一种能够反复和交替拉伸和压缩而不对带的期望性能产生不利影响的带。
本发明的另一个目的是提供一种带,其中在包绕各种辊或筒时所述带的弹性允许所述带的两个表面基于带的取向而拉伸和伸长以及压缩和缩短。
本发明的又一个目的是提供一种多基布带,其中所述基布层中至少一个是弹性的。
本发明的另一个目的是提供一种具有弹性基布层的弹性带,其中所述带的弹性得自用于构造所述弹性基布层的弹性纤维。
本发明的再一个目的是提供一种具有用于其内侧机器侧和外侧产品侧表面的针刺絮层的弹性带。
本发明的又一个目的是提供一种能够利用多种纺织方法生产的弹性带。
本发明的再一个目的是提供一种更耐用的导致使用寿命增加的带。
本发明提供这些和其它目的和优点。在这方面,本发明涉及一种用于制造纺织品的机器用带。本发明的带包括常规基布层、弹性基布层和从每个基布层外表面针刺到两个基布层中的絮纤维。弹性基布层是平织的,并利用由天然橡胶、丁腈橡胶或硅橡胶制成的弹性纤维构造。此外,可以使用诸如但不限于
Figure A20068003223200091
Figure A20068003223200092
的合成材料来构造弹性基布层。为在所述絮针刺工艺过程中保护弹性纤维免受明显损坏,弹性纤维涂有聚合物树脂,例如聚氨酯或硅氧烷。作为替代方案,可将弹性纤维加工成复合纱线,使得弹性纤维主要在纱线的芯部或中心部分内,并且包缠有诸如聚酯的纤维外层。该外层可以是围绕弹性芯加捻或螺旋缠绕的复丝纱线,或可以具有全复丝结构。为进一步保护复合弹性纱线免受明显的针刺损坏,复合纱线还可以涂有聚合物树脂,例如聚氨酯或硅氧烷。
使得本发明具备新颖性的各种特征在所附权利要求中具体指出,所附权利要求形成本公开内容的一部分。为了更好地理解本发明、其操作优点和使用其所获得的特定目的,参考所附描述性部分,其中本发明的优选实施方案在附图中示出,附图中对应部件用相同的附图标记标出。

具体实施方式
本发明涉及一种用于纺织品制造中的多基布针刺带。如前讨论的,现有技术的带存在问题,因为它们的非弹性使带的表面变得破裂和不规则,在被加工的纺织布料上产生印痕。此外,与现有技术的带相关的问题导致使用寿命较短的较不耐用的带。
本发明提供一种弹性和耐用性优于现有带的带。图2描述根据本发明一个实施方案构造的多基布针刺带的结构。如图所示,常规基布层14靠近带2的内侧机器侧4设置,而弹性基布层16靠近带2的外侧产品侧6设置。为了使常规基布层14和弹性基布层16相互连接,将顶部或外侧絮层18和底部或内侧絮层20从每个基布层的外表面针刺到两个基布层14和16中。因此,针刺的絮纤维22在物理上使所述两个层相互连接。絮层18和20还提供产品侧和机器侧接触表面。
图3描述根据本发明另一个实施方案构造的多基布针刺带。如图所示,常规基布层14靠近带2的内侧机器侧4设置,而弹性基布层16靠近带2的外侧产品侧6设置。但是,在该实施方案中,常规基布层14和弹性基布层16用额外的絮层24隔开。通过将该额外的絮层24加入到带2中,弹性基布层16的位置更靠近带2的外侧产品侧表面6。为了使常规基布层14、额外的絮层24和弹性基布层16相互连接,将顶部或外侧絮层18和底部或内侧絮层20从每个基布层的外表面针刺到额外的絮层24和两个基布层14和16中。因此,针刺的絮纤维22在物理上使所述三个层互相连接。絮层18和20还提供产品侧和机器侧接触表面。图4是根据本发明的该实施方案构造的带的横截面照片。
由于在所公开的两个实施方案中弹性基布层16的位置更靠近带2的外侧产品侧表面6,因此所述带变得更具柔性。因此,带2柔性的增加减少了在外侧絮层18中不连贯部分或不规则部分的形成,由此减少了所加工纺织布料上的印痕。如本领域技术人员容易理解的,还可以包括靠近带2内侧机器侧4的弹性基布层16。这同样导致带在其内侧机器侧4上的柔性增加。
常规基布层14可由单丝、合股单丝、复丝或合股复丝纱线或纤维机织或针织而成。纱线通常由本领域技术人员用于该目的的诸如聚酰胺和聚酯树脂的合成聚合物树脂中的任何一种挤出而成。
优选平织弹性基布层16。但是,标准弹性纤维不能用于弹性基布层16,因为标准弹性纤维不适合用于针刺过程,原因是针刺可能损坏纤维。因此,弹性纤维必须进一步加工以包括保护层,其可以是物理或化学处理。适合用于弹性层16的弹性纤维包括但不限于天然橡胶、丁腈橡胶或硅橡胶、
Figure A20068003223200111
Figure A20068003223200112
保护弹性纤维的一种途径是将纤维加工成复合纱,使得弹性纤维主要在纱线的芯或中心部分内并用诸如但不限于聚酰胺或聚酯的纤维外保护层包缠。该外保护层可以是围绕所述弹性芯加捻或螺旋缠绕的复丝纱,或者它可以具有全复丝结构。
当诸如聚酰胺和聚酯的纤维用于外保护层时,为了使弹性芯纤维保持它们的弹性,外保护层可包括以螺旋方式沿相反方向包绕弹性芯的两个纤维层。也就是说,如图5所示,外保护层的第一纤维层50沿一个方向包缠或螺旋缠绕到弹性芯56上。一旦第一纤维层50螺旋缠绕好,第二纤维层52就沿与第一层的方向相反的方向包缠或螺旋缠绕到第一纤维层50上。
在该结构中,当弹性复合纱不受张力或松弛时,螺旋缠绕的外保护层保持“闭合”。这使弹性芯56完全被外保护层覆盖,防止弹性芯56在针刺过程中受到明显损坏。如图5所示,当复合纱58沿图中所示方向受到张力或被拉伸时,外保护层的螺旋缠绕的第一纤维50和第二纤维52“打开”成“X”形54。这允许弹性芯56并由此允许复合纱58沿图中所示方向拉伸或展开。
作为替代方案,可通过应用诸如但不限于聚氨酯或硅氧烷的聚合物涂层来保护所述弹性纤维。
用这些涂层处理弹性纤维防止明显的针刺损坏并保证絮纤维和弹性纱之间的良好附着。这些涂层还可以涂覆到复合纱上以进一步提供保护以免受明显的针刺损坏并保证絮纤维和弹性纱之间的良好附着。保护涂层还包括在弹性纱上喷涂或浸涂的涂层。涂层还可以是熔粘到纱线上的皮形式或例如在纱线挤出或其它本领域技术人员公知的生产纱线方法过程中生产的所谓皮/芯纱线形式。处理弹性纱线的纱线表面的其它方法对本领域技术人员而言是显而易见的。
而且,因为本发明的带的弹性源于由弹性纱线或纤维构造的弹性层,所以本发明的带不限于平织。相反,本领域技术人员公知的其它织物成形技术可用于构造本发明的弹性层。
此外,虽然以针刺作为用于将层合结构的层连接起来的方法,但是其它方法对本领域技术人员而言将是显而易见的。例如,如果某些层的组分含有熔点较低的材料,则尤其可采用热熔法层合或连接。在这方面,一个或多个絮层可包括“低熔”粘合纤维,尤其是在絮具有内部絮层的情况下。人们可能考虑针刺和某种热熔合或适合于此目的的其它连接机理的组合。在这方面,这种组合会降低将所述结构保持在一起所需要的针刺总量,对使弹性纱线损坏最小化的期望结果产生积极影响。在例如熔合连接的情况下,熔合的量和“低熔”材料的量及其位置将不得不在使带以期望的方式操作从而沿纵向伸长和松弛的需要以及全厚度压缩和回弹(resiliciency)之间取得平衡。过多的“熔合”会影响期望的弹性性能,因此需要存在恰当的平衡。
尽管本文已经详细说明了本发明的优选实施方案及其改进,但是应理解本发明不限于该具体的实施方案和改进,其它改进和变化可由本领域的技术人员实现,而不脱离如所附权利要求限定的本发明的精神和范围。根据本发明的本发明的带的使用不限于使织物防缩的机器,换言之,本发明的带可用于对带的质量和使用寿命具有上述需要的任何地方。
