下面结合实施例， 并参照附图， 对本发明目的的实现、 功能特点及优点作进一步说
具体实施方式
如图 la和图 lb所示， 本发明提供一种具有双向可伸縮的直立结构纤维棉结构实施 例。
该具有双向可伸縮的直立结构纤维棉包括： 由梳棉机将纤维梳理同一方向且同均厚 度的纤维层 3叠加而成， 构成纤维棉的纤维层 3的沿纤维方向， 即纤维层 3的纵向设有 纤维密度或 /和厚度小于纤维层 3其他部位的纤维槽 31 (或纤维间隙） 形成的皱折状。 所述纤维槽 31可以均匀设置在纤维层 3上， 且相邻的纤维槽 31 (或纤维间隙） 相互平 行。所述双向是指在两个相互垂直的方向上，例如所述直立结构纤维棉在平面座标系中， 其沿 X轴方向 （沿即直立结构纤维棉叠加或纤维槽 31方向）和 Y轴方向 （沿即直立结 构纤维棉叠加或纤维槽 31 垂直方向） 与上申縮性是最好的， 在其他方向上也具有伸縮 性， 但与 X轴方向和 Y轴方向上伸縮性相比， 其他方向的伸縮性较差。
由于在纤维层 3铺网叠加形成的直立结构的纤维棉时， 在沿纤维层 3长度方向， 即 纤维层 3的纵向上的纤维槽 31 (或纤维间隙）在纤维棉的横向上具有伸縮性， 即该纤维 棉在与纤维槽 31 (或纤维间隙）垂直方向上具有伸縮性。 同时纤维层 3铺网叠加时， 在 纤维棉的纵向设有间隙， 该间隙使得纤维棉在与纤维层 3叠加方向， 即在该间隙垂直方 向上具有伸縮性。由于该结构的纤维棉在双向具有良好的伸縮性，可以广泛用汽车坐垫、 沙发， 也可以用于女性内衣如胸罩衬， 避免只有一个方向伸縮时产生变形。
如图 2或图 3所示， 本发明另一目是提供一种具有双向可伸縮的直立结构纤维棉 的生产装置实施例。
该具有双向可伸縮的直立结构纤维棉生产装置包括： 锡林 1和道夫 2， 在所述道夫 2外表面设有针布结构 21， 该针布结构 21 由多个均匀分布在一个圆上的针布构成， 该 针布的数量可以根据需要进行设置， 如一个、 两个或多个； 当所述针布结构 21 由至少 两个针布结构成时， 至少两个针布均匀分布在同一个圆上。 所述针布结构 21 的数量可 以根据需要进行设置， 例如可以设一组、 两组或两组以上， 当该针布结构 21 的数量为 两组或两组以上时， 每组所述针布结构 21之间相互平行， 每组所述针布结构 21沿道夫 2 的轴向间距， 即每组针布结构 21 之间的间距可以根据需要进行设置， 所述针布结构 21之间的距离越小则在所述纤维层 3上形成的纤维槽 31 (或纤维间隙） 也就越多， 成 型后的纤维棉在该方向上伸縮性也越大， 其他结构与成型过程和设置与现有技术相同， 不再赘述。
在所述道夫 2工作时， 在缠有针布结构 21的道夫 2才能从锡林 1上剥下纤维层 3， 针布结构 21之间的间隙以及针布之间是不能从锡林 1上剥下纤维的， 因此得到的纤维 层 3为横向有纤维槽 31 (或纤维间隙）的纤维层。该纤维层 3再通过竖棉机构得到直立 结构的纤维棉， 由于纤维棉在其纵向和横向都有纤维槽 31 (或纤维间隙）， 因而具备双 向弹性。 在本实施例中， 所述针布结构 21在道夫 2的轴向之间的距离相等， 即每组针 布结构 21之间的距离相同， 在纤维层上形成的纤维槽 31 (或纤维间隙） 距离相等， 由 该纤维层形成的纤维棉在与纤维槽 31 (或纤维间隙） 垂直方向上伸縮性更均匀。
如图 4所示， 本发明还提供另一种具有双向可伸縮的直立结构纤维棉的生产装置 实施例。
所述直立结构纤维棉生产装置包括： 梳棉机 Γ和在该梳棉机 Γ输出口设有两个对 辊 4， 其中一只对棍 4外表面设有多组相互平行的倒刺结构 41， 每组倒刺结构 41上倒 刺位于同一个圆上， 其他结构与上述实施例相同， 不再赘述。优选地， 所述倒刺结构 41 在对棍 4的轴向间的距离相等。
在梳棉机 梳理出正常的纤维层 3后， 该纤维层 3从两个对辊 4之间通过， 由于 其中一只对辊 4上有倒刺结构 41，其可以带走一部分纤维，从而在纤维层 3的横向上形 成纤维槽 31 (或纤维间隙）， 该纤维层 3再通过竖棉机构得到直立结构的纤维棉， 由于 纤维棉在其纵向和横向都有纤维槽 31 (或纤维间隙）， 因而具备双向弹性。
如图 5所示， 本发明又一目是提供一种由短纤维制成的具有双向可伸縮的直立结 构纤维棉生产方法的实施例。
该具有双向可伸縮的直立结构维棉生产方法以下步骤包括：
S10 步骤， 梳棉步骤， 将纤维梳理成纤维沿一个方向的纤维层； 具体地说， 可以 由梳棉机对纤维进行梳棉处理， 特别是短纤维进行梳理处理， 将纤维梳理形成沿一个方 的纤维层。
S11步骤， 挑棉步骤， 具体地说， 对 S10步骤产生的纤维层进行挑棉， 在所述纤维 层沿其长度方向上形成纤维槽或纤维间隙； 例如可采用上述实施例中的道夫 2; 在道夫 2工作时， 在缠有针布结构 21的道夫 2才能从锡林 1上剥下纤维层 3， 针布结构 21之 间的间隙以及针布之间是不能从锡林 1上剥下纤维的， 因此得到的纤维层 3为横向有纤 维槽 31 (或纤维间隙） 的纤维层， 在该纤维槽 31 (或纤维间隙） 作用下纤维棉在其横 向上具有伸縮性。
也可以由纤维层 3从两个对辊 4之间通过， 由于其中一只对棍 4外表面设有多组 相互平行的倒刺结构 41， 每组倒刺结构 41 上倒刺位于同一个圆上， 所述倒刺结构 41 在对棍 4的轴向间的距离相等； 设有倒刺结构 41的一只对辊 4带走一部分纤维， 从而 在纤维层 3的长度方向上（纵向）上形成纤维槽 31 (或纤维间隙）。由于该纤维槽 31 (或 纤维间隙）的纤维层 3成型得到直立结构的纤维棉， 在与纤维槽 31 (或纤维间隙）垂直 方向， 即纤维层 3的横向具有伸縮性。
S12 步骤， 铺网成型步骤， 再将设有纤维槽或纤维间隙的纤维层在竖直方向的铺 网叠加并成型， 即将上述 S11步骤中挑过棉的纤维层进行铺网叠加， 使纤维层叠加成具 有一定厚度和长度的块状纤维棉并进行成型； 由于在纤维层 3叠加形成的直立结构的纤 维棉时， 沿纤维层的长度方向上形成间隙， 该间隙在纤维棉的纵向上形成可伸縮性。 因 此由所述纤维层铺网叠加形成的纤维棉在其横向和纵向上都具有申请性，可以广泛用汽 车坐垫、 沙发， 也可以用于女性内衣如胸罩衬， 避免只有一个方向伸縮时产生变形。
以上所述仅为本发明的优选实施例， 并非因此限制本发明的专利范围， 凡是利用本 发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关 的技术领域， 均同理包括在本发明的专利。
