本发明涉及擦拭巾技术领域，尤其涉及应用于个人护理、婴幼儿护理用的一种防掉毛、增加力学强度的复合擦拭巾及其制造方法。
 背景技术
目前，擦拭巾由于携带及收纳相当的方便，且使用便利，因此受到广大消费者的喜爱。在日常生活中常常需要用到擦拭巾，例如当父母替婴儿更换尿布时，或是餐厅用餐时，或是化妆护理皮肤时。可见，擦拭巾在个人护理、婴幼儿护理方面应用越来越广泛。擦拭巾可以是水刺无纺布制品，也可以是熔喷复合无纺布制品。较传统的布类擦拭巾，其生产方法方便，价格低廉，并且干湿均可使用。
 技术问题
但是现有的熔喷复合无纺布是由熔喷纤维层作为表面层，木浆纤维层作为中间层，经复合后而形成的，由于木浆纤维长度较短，容易从熔喷纤维层掉出，即出现所谓的“掉毛”现象，并且熔喷纤维层由熔喷纤维铺网而成，熔喷纤维为短纤维，纤维之间固结后，形成的熔喷纤维层力学性能较低，从而影响熔喷复合擦拭巾的力学性能。
 技术解决方案
本发明的目的在于提供一种可有效防止掉毛、增加力学性能的复合擦拭巾及其制造方法，克服现有产品及生产方法的缺陷。
为实现上述目的，本发明的解决技术方案是：一种复合擦拭巾，所述擦拭巾的上表面层与下表面层为熔喷纤维网，所述擦拭巾的中间层为木浆纤维网，在所述上表面层或/和下表面层的熔喷纤维网和木浆纤维网之间具有由纺粘长纤维构成的纺粘长纤维网，所述上表面层与下表面层的熔喷纤维网中的熔喷短纤维交织于邻接的纺粘长纤维网或木浆纤维网之中。
所述纺粘长纤维为单组分纺粘长纤维、双组份纺粘长纤维或两者共混纺粘长纤维。
所述纺粘长纤维网的克重为2～20g/m 2。
所述熔喷短纤维为单组分熔喷短纤维、双组份熔喷短纤维或两者共混的熔喷短纤维。
所述熔喷短纤维的直径≤10um。
所述的双组份纺粘长纤维和所述的双组份熔喷短纤维分别由熔点相差20℃以上，且表面含有低熔点树脂的纤维构成，纤维结构为双组份皮芯型、双组份橘瓣型或双组份并列型。
所述木浆纤维网的重量占所述擦拭巾总重量的百分比大于50%。
所述木浆纤维网的重量占所述擦拭巾总重量的百分比为65%～80%。
一种复合擦拭巾的制造方法，包括下列步骤：（1）木浆通过开松辊开松打散，在辅助气流的作用下通过喷管形成木浆纤维网；（2）采用熔喷法工艺，将热塑性树脂加热，熔融后进入熔喷纺丝装置，在熔喷纺丝装置中利用热气流将从熔喷喷丝板的熔喷喷丝孔中喷出的热塑性树脂的熔体细流吹散成纤维直径≤10μm的纤维束，从而伴随热气流形成熔喷纤维网；（3）采用纺粘法工艺，将热塑性树脂加热，熔融后进入纺粘纺丝装置，在纺粘纺丝装置中将加热后的热塑性树脂的熔体变为熔体细流，然后通过纺粘喷丝板的纺粘喷丝孔中喷出，侧吹冷风冷却，并通过牵伸装置对纺粘长纤维进行牵伸后形成纺粘长纤维网；（4）所形成的熔喷纤维网分别与邻接的木浆纤维网或纺粘长纤维网的侧面处相交汇，形成两侧是熔喷纤维网，中间为木浆纤维网和纺粘长纤维网的多层结构纤维网；（5）所述多层纤维网通过加热装置将纤维网固结在一起，形成上、下两层为熔喷纤维网，中间层为木浆纤维网和纺粘长纤维网的复合擦拭巾。
所述熔喷喷丝孔和所述的纺粘喷丝孔的结构类型为单组分喷丝孔、双组份喷丝孔或两者相互混合排列。
所述的双组份喷丝孔为为皮芯型、橘瓣型或并列型。
所述加热装置为热风烘箱、热轧辊或两者相结合。
 有益效果
采用上述技术方案后，由于本发明的复合擦拭巾在表面层熔喷纤维网和中间层木浆纤维网之间还具有纺粘长纤维网，在制造过程中，熔喷纤维网中的熔喷短纤维部分交织于纺粘长纤维网和木浆纤维网之中，形成的多层结构纤维网通过加热装置处理时，纺粘长纤维网会与熔喷纤维网和木浆纤维网相互粘连在一起，构成交织的网状结构，使得木浆短纤难以移动，进而所形成的擦拭巾在使用时不会出现“掉毛”的现象，有效防止擦拭巾配合液体使用时木浆短纤维在吸水后团聚的现象发生，同时纺粘长纤维网由纺粘长纤维组成，由于纤维本身力学强度相较于熔喷短纤维会大大提高，在纤维网固结后所形成的复合擦拭巾的力学强度也大大提高，解决了擦拭巾在使用时容易断裂，力学强度低的问题。

 本发明的实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
实施例1。
如图1所示，本发明揭示了一种复合擦拭巾的制造方法，包括下列步骤：（1）木浆11通过开松辊A1开松打散，在辅助气流的作用下通过喷管B1形成木浆纤维网12。
（2）采用熔喷法工艺，将热塑性树脂聚丙烯PP加热，熔融后进入熔喷纺丝装置C1、C1’，在熔喷纺丝装置C1、C1’中利用热气流将从熔喷喷丝板的熔喷喷丝孔中喷出的热塑性树脂的熔体细流吹散成纤维直径≤10μm的纤维束，伴随热气流形成熔喷纤维网13、14。
（3）采用纺粘法工艺，将热塑性树脂聚丙烯PP加热，熔融后进入纺粘纺丝装置D1，在纺粘纺丝装置D1中将加热后的热塑性树脂的熔体变为熔体细流，然后通过纺粘喷丝板的纺粘喷丝孔中喷出，侧吹冷风E1冷却，并通过牵伸装置F1对纺粘长纤维进行牵伸后形成纺粘长纤维网15。
（4）所形成的熔喷纤维网13、14分别与木浆纤维网12和纺粘长纤维网15的侧面处相交汇，形成两侧是熔喷纤维网13、14，中间为木浆纤维网12和纺粘长纤维网15的多层结构纤维网16。
（5）所述多层纤维网16通过热轧辊G1将纤维网固结在一起，形成上、下两层为熔喷纤维网13、14，中间层为木浆纤维网12和纺粘长纤维网15的复合擦拭巾17。
如图2所示，本发明还揭示了一种可应用上述复合擦拭巾的制造方法制成的复合擦拭巾17，所述擦拭巾的上、下两表面层为熔喷纤维网13、14，中间层为木浆纤维网12，在所述的上表面层或下表面层熔喷纤维网13/14和木浆纤维网12之间具有由纺粘长纤维构成的纺粘长纤维网15。当然，亦可同时在上表面层与下表面层的熔喷纤维13、14与木浆纤维网12之间同时设置由纺粘长纤维构成的纺粘长纤维网15。所述的上表面层或下表面层的熔喷纤维网13/14中的熔喷短纤维部分交织于邻接于熔喷纤维网的纺粘长纤维网15或木浆纤维网12之中。
其中，纺粘长纤维网15的克重为2～20g/m 2，此实施例中纺粘长纤维网15的克重为10g/m 2。木浆纤维网12的重量占所述复合擦拭巾17总重量的百分比大于50%，最佳为65%～80%；此实施例中木浆纤维网12的重量占所述复合擦拭巾17总重量的百分比为70%。
采用上述技术方案后，由于纺粘长纤维网15的存在，熔喷纤维网13、14中的熔喷短纤维部分交织于熔喷纤维网13、14邻接的纺粘长纤维网15或木浆纤维网12之中，通过热轧辊G1后形成交织的网状结构，令木浆短纤难以移动，以防止所形成的复合擦拭巾17在使用时出现的“掉毛”现象，也有效防止擦拭巾配合液体使用时木浆短纤维在吸水后团聚的现象发生，同时纺粘长纤维网15由纺粘长纤维组成，由于纤维本身力学强度相较于熔喷短纤维会大大提高，从而解决了擦拭巾在使用时容易断裂，力学强度低的问题。
实施例2。
如图3所示，本发明揭示了一种复合擦拭巾的制造方法，包括下列步骤：（1）木浆21通过开松辊A2开松打散，在辅助气流的作用下通过喷管B2形成木浆纤维网22。
（2）采用熔喷法工艺，将热塑性树脂聚丙烯PP和高密度聚乙烯HDPE分别加热，熔融后进入熔喷纺丝装置C2、C2’，在熔喷纺丝装置C2、C2’中利用热气流将从熔喷喷丝板的双组份熔喷喷丝孔中喷出的热塑性树脂的溶体细流吹散成纤维直径≤10μm的纤维束，伴随热气流形成由聚丙烯PP和高密度聚乙烯HDPE组成且表面含有高密度聚乙烯HDPE的双组份熔喷纤维构成的熔喷纤维网23、24。
（3）采用纺粘法工艺，将热塑性树脂聚丙烯PP和高密度聚乙烯HDPE分别加热，熔融后进入纺粘纺丝装置D2，在纺粘纺丝装置D2中将加热后的热塑性树脂的熔体变为熔体细流，然后通过纺粘喷丝板的双组份纺粘喷丝孔中喷出，侧吹冷风E2冷却，并通过牵伸装置F2对纺粘长纤维进行牵伸后形成纺粘长纤维网25，其中纺粘长纤维是由聚丙烯PP和高密度聚乙烯HDPE组成的，且表面含有高密度聚乙烯HDPE的双组份纺粘长纤维。
（4）所形成的熔喷纤维网23、24分别与木浆纤维网22和纺粘长纤维网25的侧面处相交汇，形成两侧是熔喷纤维网23、24，中间为木浆纤维网22和纺粘长纤维网25的多层结构纤维网26。
（5）所述多层纤维网26通过热风烘箱H2将纤维网固结在一起，形成上、下两层为熔喷纤维网23、24，中间层为木浆纤维网22和纺粘长纤维网25的复合擦拭巾27。
如图4所示，本发明还揭示了一种可应用上述复合擦拭巾的制造方法制成的复合擦拭巾27，所述擦拭巾的上、下两表面层为熔喷纤维网23、24，中间层为木浆纤维网22，在所述的上表面层或下表面层熔喷纤维网23/24和木浆纤维网22之间具有由纺粘长纤维构成的纺粘长纤维网25。当然，亦可同时在上表面层与下表面层的熔喷纤维23、24与木浆纤维网22之间同时设置由纺粘长纤维构成的纺粘长纤维网25。所述的上表面层或下表面层的熔喷纤维网23/24中的熔喷短纤维部分交织于邻接于熔喷纤维网的纺粘长纤维网25或木浆纤维网22之中。
其中，木浆纤维网22的重量占所述复合擦拭巾27总重量的百分比大于50%，最佳为65%～80%；此实施例中木浆纤维网12的重量占所述复合擦拭巾17总重量的百分比为70%。纺粘长纤维网25的克重为2～20g/m 2，此实施例中纺粘长纤维网15的克重为15g/m 2；双组份纺粘长纤维和所述的双组份熔喷短纤维的纤维结构为双组份皮芯型28（芯层树脂28a为聚丙烯PP，皮层树脂28b为高密度聚乙烯HDPE，且聚丙烯PP和高密度聚乙烯HDPE的熔点相差20℃以上）（见图5A所示）、双组份橘瓣型29（一种树脂29a为聚丙烯PP，另一种树脂29b为高密度聚乙烯HDPE，且聚丙烯PP和高密度聚乙烯HDPE的熔点相差20℃以上）（见图5B所示）或双组份并列型30（一种树脂30a为聚丙烯PP，另一种树脂30b为高密度聚乙烯HDPE，且聚丙烯PP和高密度聚乙烯HDPE的熔点相差20℃以上）（见图5C所示）。
采用上述技术方案后，由于纺粘长纤维网25和熔喷纤维网23、24 为双组份纤维结构，两种树脂的熔点相差20℃以上，并且表层含有低熔点树脂，在通过加热装置热风烘箱H2时，双组份纺粘长纤维和双组份熔喷短纤维的表层的低熔点树脂开始熔融，使得纤维之间互相粘连，并且在熔喷纤维网23、24中的熔喷短纤维部分交织于熔喷纤维网23、24邻接的纺粘长纤维网25或木浆纤维网22之中，使得木浆短纤维在由熔喷纤维网23、24 和纺粘长纤维网形成的交织网中难以移动，所形成的复合擦拭巾27在使用时不会出现“掉毛”的现象，也有效防止复合擦拭巾配合液体使用时木浆短纤维在吸水后团聚的现象发生，同时纺粘长纤维网25由纺粘长纤维组成，由于纤维本身力学强度相较于熔喷短纤维会大大提高，从而解决了擦拭巾在使用时容易断裂，力学强度低的问题。
实施例3。
如图6、7所示，本发明揭示了一种复合擦拭巾的制造方法以及用该方法制造的复合擦拭巾37，包括下列步骤：（1）木浆31通过开松辊A3开松打散，在辅助气流的作用下通过喷管B3形成木浆纤维网32。
（2）采用熔喷法工艺，将热塑性树脂聚丙烯PP和高密度聚乙烯HDPE分别加热，熔融后进入熔喷纺丝装置C3、C3’，在熔喷纺丝装置C3、C3’中利用热气流将从熔喷喷丝板的双组份熔喷喷丝孔中喷出的热塑性树脂的溶体细流吹散成纤维直径≤10μm的纤维束，从而伴随热气流形成由聚丙烯PP和高密度聚乙烯HDPE组成的，且表面含有高密度聚乙烯HDPE的双组份熔喷纤维构成的熔喷纤维网33、34。
（3）采用纺粘法工艺，将热塑性树脂聚丙烯PP加热，熔融后进入纺粘纺丝装置D3，在纺粘纺丝装置D3中将加热后的热塑性树脂的熔体变为熔体细流，然后通过纺粘喷丝板的喷丝孔中喷出，侧吹冷风E3冷却，并通过牵伸装置F3对纺粘长纤维进行牵伸后形成纺粘长纤维网35。
（4）采用纺粘法工艺，将热塑性树脂聚丙烯PP加热，熔融后进入纺粘纺丝装置D3’，在纺粘纺丝装置D3’中将加热后的热塑性树脂的熔体变为熔体细流，然后通过纺粘喷丝板的喷丝孔中喷出，侧吹冷风E3’冷却，并通过牵伸装置F3’对纺粘长纤维进行牵伸后形成纺粘长纤维网35’。
（5）所形成的熔喷纤维网33、34分别与木浆纤维网32和纺粘长纤维网35、35’的侧面处相交汇，形成两侧表面是熔喷纤维网33、34，中间层为两侧为纺粘长纤维网35、35’和中间为木浆纤维网32的多层结构纤维网36。
（6）所述多层纤维网36通过热风烘箱H3和热轧辊G3将纤维网固结在一起，形成上、下两层为熔喷纤维网33、34，中间层为两侧为纺粘长纤维网35、35’和中间为木浆纤维网32的复合擦拭巾37（见图7所示）。其中，木浆纤维网32的重量占所述复合擦拭巾37总重量的百分比为80%；纺粘长纤维网35、35’的克重分布为20g/m 2。
采用上述技术方案后，由于熔喷纤维网33、34为双组份纤维结构，两种树脂的熔点相差20℃以上，并且表层含有低熔点树脂，因此，在通过加热装置热风烘箱H2时，双组份熔喷短纤维的表层的低熔点树脂开始熔融，使得纤维之间互相粘连，并且纺粘长纤维网35，35’的存在，会与熔喷纤维网33、34和木浆纤维网32相互粘连在一起，在通过热轧辊G2时，多层结构纤维网36会形成交织的网状结构，使得木浆短纤维在由上、下表面层熔喷纤维网33、34 和中间层中两侧纺粘长纤维网35、35’形成的交织网中难以移动，使得所形成的复合擦拭巾37在使用时更不会出现“掉毛”的现象，同时也有效防止复合擦拭巾配合液体使用时木浆短纤维在吸水后团聚的现象发生。
