Abstract

本发明公开了一种擦拭巾，所述擦拭巾的上、下两层为熔喷纤维网，所述擦拭巾的中间层为含有热熔胶粘物质的木浆纤维网，所述熔喷纤维网的熔喷纤维穿插于木浆纤维网中，本发明还公开了一种擦拭巾的制造方法，可用于制造本发明的吸水擦拭巾，所述擦拭巾有效防止所形成的擦拭巾在使用时不会出现“掉毛”的现象，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。

Description

一种擦拭巾及其制造方法
技术领域
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、防团聚的擦拭巾及其制造方法。
背景技术
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。
目前，擦拭巾可以是水刺无纺布制品，也可以是纺粘无纺布制品。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。
中国发明专利申请号为93118457.6公开了一种耐磨纤维无纺织复合结构物，它由下列两组分组成 (1）具有第一外表面、第二外表面和里部的熔喷纤维基体，和（2）至少一种结合进熔喷纤维基体中使熔喷纤维在无纺织结构的每个外表面附近的浓度至少为约60%（重量），且熔喷纤维在里部的浓度小于约40%（重量）的其它纤维材料。这种擦拭布提供了有用的强度和低掉绒特性以及比相同级分的均匀混合物耐磨性大至少约25%的耐磨性。该擦拭布通过表面的熔喷纤维形成的熔喷层较致密,从而在一定程度上防止了里部其他纤维材料在使用过程中掉落出来，但是里部其他纤维之间没有相互粘连固定，在使用时“掉毛” 现象也会出现，并且在吸水后擦拭时有可能会出现团聚现象，从而影响了擦拭巾的使用效果和减少了使用寿命。
发明内容
本发明的目的在于提供一种可有效防止掉毛、团聚的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：
一种擦拭巾，所述擦拭巾的上、下两层为熔喷纤维网，所述擦拭巾的中间层为含有热熔胶粘物质的木浆纤维网，所述熔喷纤维网的熔喷纤维穿插于木浆纤维网中。
所述热熔胶粘物质为低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维或它们的混合物。
所述热熔胶粘物质含量为1～15g/m2。
所述热熔胶粘物质的含量为2～5g/m2。
所述熔喷纤维为聚烯烃纤维、聚酯纤维、聚酰胺纤维、聚氨酯纤维、聚乳酸纤维或它们的混合物。
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，与热熔胶粘物质混合后在辅助气流的作用下通过喷管形成含有热熔胶粘物质的木浆纤维网；
（2）采用熔喷法工艺，将热塑性树脂加热，熔融，利用高温、高速热气流将从喷丝板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熔喷纤维网，并与含有热熔胶粘物质的木浆纤维网的两个侧面处相交汇，形成两侧是熔喷纤维网，中间为含有热熔胶粘物质的木浆纤维网的多层结构纤维网；
（3）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，中间层为含有热熔胶粘物质的木浆纤维网的擦拭巾。
所述热熔胶粘物质为低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维或它们的混合物。
所述加热装置为热风烘箱、热轧辊或两者相结合。
采用上述技术方案后，可应用本发明的擦拭巾制造方法制得本发明的擦拭巾，由于本发明的擦拭巾的中间层的木浆纤维网中含有热熔胶粘物质，在制造过程中，形成的多层结构纤维网通过加热装置处理时，热熔胶粘物质会在热风环境下，表面开始熔融，在热熔胶粘物质与纤维相互接触时，则会相互粘连在一起，形成交织的网状结构，因此，在一定程度上将中间层的木浆短纤固定在网状结构中，使得木浆短纤难以移动，从而防止所形成的擦拭巾在使用时不会出现“掉毛”的现象，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。

具体实施方式
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。
如图1所示，本发明揭示了一种擦拭巾的制造方法，包括下列步骤：
（1）将木浆1通过开松辊A开松打散，与热熔胶粘物质2混合后在辅助气流的作用下通过喷管B形成含有热熔胶粘物质2的木浆纤维网3，其中，热熔胶粘物质2可以为低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维或它们的混合物，它们的混合物是由低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维一起混合或者任选两种混合而成，含量为3g/m2。
（2）采用熔喷法工艺，将热塑性树脂加热，熔融，利用高温、高速热气流将从喷丝板C1、C2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熔喷纤维网4、5，并与含有热熔胶粘物质2的木浆纤维网3的两个侧面处相交汇，形成两侧是熔喷纤维网4、5，中间为含有热熔胶粘物质2的木浆纤维网3的多层结构纤维网6，其中，熔喷纤维可以为聚烯烃纤维、聚酯纤维、聚酰胺纤维、聚氨酯纤维、聚乳酸纤维或它们的混合物，它们的混合物是由聚烯烃纤维、聚酯纤维、聚酰胺纤维、聚氨酯纤维、聚乳酸纤维一起混合或者任选两种/三种/四种混合而成。
（3）所述多层结构纤维网6通过热风烘箱D和/或一对啮合的热轧辊E将纤维网固结在一起，形成上、下两层为熔喷纤维网4、5，中间层为含有热熔胶粘物质2的木浆纤维网3的擦拭巾7，其中，熔喷纤维网4、5的熔喷纤维穿插于木浆纤维网3中，木浆纤维网3的重量占擦拭巾7总重量的百分比大于50%，较佳的，木浆纤维网3的重量占擦拭巾7总重量的百分比为65%～80%。
如图2所示，本发明还揭示了一种可应用上述擦拭巾的制造方法制成的擦拭巾，其为层状结构，所述擦拭巾7的上、下两层为熔喷纤维网4、5，中间层为含有热熔胶粘物质2的木浆纤维网3，所述熔喷纤维网4、5的熔喷纤维穿插于木浆纤维网3中，其中所述热熔胶粘物质含量可以为1～15g/m2，较佳的，所述热熔胶粘物质的含量为2～5g/m2，于本实施例中，所述热熔胶粘物质的含量为3g/m2，所述热熔胶粘物质2可以为低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维或它们的混合物，它们的混合物是由低熔点聚酯纤维、ES短纤维、双组份纺粘长纤维一起混合或者任选两种混合而成。
因此，该擦拭布7是通过于上、下两层形成较致密的熔喷纤维网4、5，从而在一定程度上防止了里部其他纤维材料在使用过程中掉落出来，并且中间层的木浆纤维网3中含有热熔胶粘物质2，在制造过程中，形成的多层结构纤维网6通过热风烘箱和/或热轧辊时，热熔胶粘物质2会在热风环境下，表面开始熔融，在热熔胶粘物质2与纤维相互接触时，则会相互粘连在一起，形成交织的网状结构，从而在一定程度上将中间层的木浆短纤维固定在网状结构中，使得木浆短纤难以移动，从而防止所形成的擦拭巾7在使用时出现“掉毛”的现象，也有效防止擦拭巾7配合液体使用时木浆短纤维在吸水后团聚的现象发生。
