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，中间层为木浆纤维网，其中，所述熔喷纤维网表面及与表面相邻的熔喷纤维网内部均附着有胶粘剂，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，由于熔喷纤维网内部及表面均附着有胶粘剂，使得熔喷纤维网形成一层胶粘剂膜，使得擦拭巾在使用时既阻止了表面熔喷纤维因多次摩擦而使得熔喷纤维之间在外力作用下相互脱开粘结而引起的起毛、起绒现象。
Description
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表面耐磨、防起毛的擦拭巾及其制造方法。
背景技术
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。由于擦拭巾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。所以擦拭巾在个人护理、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。为了增加擦拭巾的吸湿性能，在擦拭巾中往往会添加木浆，来提高擦拭巾的吸湿去污能力。但是木浆纤维为天然短纤维，纤维较短且不受温度影响，不易固结在一起，而仅通过纺粘工艺或水刺工艺进行结网固定，在使用时，多次摩擦后使得木浆短纤维容易脱落，造成掉毛现象，掉出影响使用寿命。
发明内容
本发明的目的在于提供一种防止表面起毛、掉毛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，中间层为木浆纤维网，其中，所述熔喷纤维网表面及与表面相邻的熔喷纤维网内部均附着有胶粘剂，所述熔喷纤维网的熔喷纤维穿插于木浆纤维网中。
所述熔喷纤维网含有纤维表面为高熔点树脂的单组份熔喷纤维、纤维表面含有低熔点树脂的纤维或两者的共混纤维。
所述高熔点树脂和低熔点树脂的熔点之差≥20℃。
所述纤维表面含有低熔点树脂的纤维为单组份熔喷纤维、双组份熔喷纤维或两者相混合。
所述双组份熔喷纤维为双组份皮芯型熔喷纤维、双组份橘瓣型熔喷纤维或双组份并列型熔喷纤维。
所述胶粘剂为热熔胶或溶剂胶。
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与所述擦拭巾总重量的百分比为65%～80%。
所述木浆纤维网中含有热熔胶粘物质。
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。
一种擦拭巾的制造方法，包括以下步骤：
（1）木浆通过开松辊开松打散，并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，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小于10um的纤维束，伴随热气流形成熔喷纤维网，并与木浆纤维网的两个侧面处相交汇，形成两侧为熔喷纤维网，中间为木浆纤维网的多层结构纤维网；
（3）通过喷胶工艺，将胶粘剂在高压热气流的作用下通过喷管将胶粘剂喷涂在两侧为熔喷纤维网，中间为木浆纤维网的多层结构纤维网的两个侧面；
（4）喷胶后的多层结构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的擦拭巾，且熔喷纤维网表面及与表面相邻的熔喷纤维网内部均附着有胶粘剂。
所述步骤（2）中，分别将两种熔点之差≥20℃的热塑性树脂加热，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小于10um的纤维束，伴随热气流形成熔喷纤维网，其中所述熔喷纤维网含有纤维表面为高熔点树脂的纤维、纤维表面含有低熔点树脂的纤维或两者的共混纤维。
所述喷丝板上含有双组份喷丝孔。
所述喷丝板上的双组份喷丝孔为皮芯型、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。
所述步骤（1）中，木浆通过开松辊开松打散，并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。
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熔喷纤维网的纤维纤度小，排布致密，有效防止了中间层的木浆短纤维的掉落。并且熔喷纤维网内部及表面均附着有胶粘剂，使得熔喷纤维网形成一层胶粘剂膜，使得擦拭巾在使用时既阻止了表面熔喷纤维因多次摩擦而使得熔喷纤维之间在外力作用下相互脱开粘结而引起的起毛、起绒现象，同时也进一步防止了中间层木浆短纤维掉出，在使用过程中出现“掉毛”从而擦拭不干净的问题。

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。
实施例1
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11通过开松辊A1开松打散，并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，将热塑性树脂加热，熔融，利用高温、高速热气流将从喷丝板C1、C1’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，伴随热气流形成的熔喷纤维网13、14，并与木浆纤维网12的两个侧面处相交汇，形成两侧为熔喷纤维网13、14，中间为木浆纤维网12的多层结构纤维网15，其中，所述熔喷纤维网13、14由纤维表面为高熔点树脂的单组份熔喷纤维组成。
（3）通过喷胶工艺，将胶粘剂在高压热气流的作用下通过喷管D1、D1’将胶粘剂喷涂在两侧为熔喷纤维网13、14，中间为木浆纤维网12的多层结构纤维网15的两个侧面。
（4）喷胶后的多层结构纤维网15通过一对啮合的热轧辊F1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11的擦拭巾16，且熔喷纤维网13、14表面及与表面相邻的熔喷纤维网13、14内部均附着有胶粘剂，木浆纤维网12的重量与所述擦拭巾16总重量的百分比为75%。
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16的上、下两层为熔喷纤维网13、14，中间层为木浆纤维网12，其中，所述熔喷纤维网13、14表面及与表面相邻的熔喷纤维网13、14内部均附着有胶粘剂，所述熔喷纤维网13、14的熔喷纤维穿插于木浆纤维网12中，所述胶粘剂可以为热熔胶或溶剂胶。
因此，由于喷胶工艺是在熔喷纤维网13、14没有固结之前进行的，所以喷胶过程中，胶粘剂会不仅会粘附在熔喷纤维网13、14表面，也会渗透到与表面相邻的熔喷纤维网13、14内部，使得熔喷纤维网13、14表面及与表面相邻的熔喷纤维网13、14内部附着有胶粘剂，在熔喷纤维网13、14形成一层胶粘剂膜17、18，使得在使用时既阻止了表面熔喷纤维因摩擦而起毛、起绒，而且也进一步防止了中间层的木浆短纤维掉出，在使用过程中出现“掉毛”现象。
实施例2
如图3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21通过开松辊A2开松打散，并与热熔胶粘物质22混合后在辅助气流的作用下通过喷管B2形成含有热熔胶粘物质22的木浆纤维网23。
(2)采用熔喷法工艺，将两种热塑性树脂分别加热，熔融后进入纺丝箱，在纺丝箱内利用高温、高速热气流将从喷丝板C2、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，伴随热气流形成熔喷纤维网24、25，其中，熔喷纤维网24、25由纤维表面为高熔点树脂的单组份熔喷纤维20和纤维表面含有低熔点树脂的熔喷纤维20’共混组成。所述熔喷纤维网24、25也可以仅含有纤维表面为高熔点树脂的单组份熔喷纤维20或者仅含有纤维表面含有低熔点树脂的熔喷纤维20’，而纤维表面含有低熔点树脂的熔喷纤维20’可以为单组份熔喷纤维、双组份熔喷纤维或两者相混合。如图5A至图5C所示，双组份熔喷纤维可以是皮芯型熔喷纤维31、双组份橘瓣型熔喷纤维33或双组份并列型熔喷纤维32，且皮芯型熔喷纤维31中皮层树脂31b的熔点低于芯层树脂31a的熔点，双组份橘瓣型熔喷纤维33、双组份并列型熔喷纤维32的其中一种树脂32b、33b的熔点低于另一种树脂32a、33a的熔点。该双组份熔喷纤维是将两种熔点之差≥20℃的热塑性树脂加热，熔融，并且由喷丝板上的喷丝孔所含有双组份喷丝孔喷出形成，所述喷丝板上的双组份喷丝孔为皮芯型、橘瓣型或并列型；然后形成的熔喷纤维网24、25在含有热熔胶粘物质22的木浆纤维网23的两个侧面处相交汇，形成两侧是含有双组份熔喷纤维的熔喷纤维网24、25，中间为含有热熔胶粘物质22的木浆纤维网23的多层结构纤维网26。
（3）通过喷胶工艺，将胶粘剂在高压热气流的作用下通过喷管D2、D2’将胶粘剂喷涂在两侧为熔喷纤维网24、25，中间为含有热熔胶粘物质22的木浆纤维网23的多层结构纤维网26的两个侧面。
（3）喷胶后的多层结构纤维网26通过热风烘箱E2和一对啮合的热轧辊F2将纤维网固结在一起，形成上、下两层为熔喷纤维网24、25，中间层为含有热熔胶粘物质22的木浆纤维网23的擦拭巾27，且熔喷纤维网24、25表面及与表面相邻的熔喷纤维网24、25内部均附着有胶粘剂。
如图4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27的上、下两层为熔喷纤维网24、25，中间层为含有热熔胶粘物质22的木浆纤维网23，其中，所述熔喷纤维网24、25表面及与表面相邻的熔喷纤维网24、25内部均附着有胶粘剂，所述熔喷纤维网24、25的熔喷纤维穿插于木浆纤维网23中，熔喷纤维网24、25由纤维表面为高熔点树脂的单组份熔喷纤维20和纤维表面含有低熔点树脂的熔喷纤维20’共混组成。而纤维表面含有低熔点树脂的熔喷纤维20’可以为单组份熔喷纤维、双组份熔喷纤维或两者相混合，所述热熔胶粘物质22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，由于喷胶工艺是在熔喷纤维网24、25没有固结之前进行的，所以喷胶过程中，胶粘剂会不仅会粘附在熔喷纤维网24、25表面，也会渗透到与表面相邻的熔喷纤维网24、25内部，使得熔喷纤维网24、25表面及与表面相邻的熔喷纤维网24、25内部附着有胶粘剂，在熔喷纤维网24、25形成一层胶粘剂膜28、29，使得在使用时既阻止了表面熔喷纤维因摩擦而起毛、起绒，而且也进一步防止了中间层木浆短纤维掉出，在使用过程中出现“掉毛”现象。并且熔喷纤维网24、25含有纤维表面含有低熔点树脂的熔喷纤维20’，该熔喷纤维20’中的低熔点树脂在热风烘箱中熔融，使得纤维之间会粘连在一起，既增加了擦拭巾的整体强度，也使得熔喷纤维排列更加致密，并且使得熔喷纤维网24、25表面附着的胶粘剂结合力更强。同时，中间层的木浆纤维网23中添加有热熔胶粘物质22，在热风烘箱中热熔胶粘物质22表面开始熔融，在一定程度上将中间层的木浆短纤维固定，使得木浆短纤难以移动，从而进一步防止所形成的擦拭巾在使用时不会出现“掉毛”的现象，增加擦拭巾的耐磨性。
