Description
技术领域
本发明涉及无纺布技术领域,具体为一种内亲水外疏水无纺布及其制备方法。
背景技术
无纺布是人们生活中最常见的布料之一,但是现有的无纺布存在防水性不足的问题,一旦下雨或水溅,很容易弄湿而对人们穿着的舒适性造成不便,甚至长时间穿着潮湿的衣服极易造成风湿等慢性疾病。疏水性的无纺布料虽然形成外接屏障,解决了布料的防水性,但此类布料的人体皮肤的吸收性较差,因此容易出现身体热量和汗液无法释放的问题,造成布料的闷热。为了解决上述问题,具有外疏水性和内亲水性的无纺布料成了研究的热点。中国专利CN201610887602公开了一种外层亲水内层输水的棉质布料,该布料被水浸湿后,内层布料的网状结构能够将内部的水快速排出至不了外层,保持内层干爽。但是,该布料的材料制备方法较复杂且采用的亲水材料并非纺织领域常见的原料制成,因此推广难度较大,同时,该布料采用内疏水层,因此人们在穿着过程中的亲肤性较差。

除非另外具体说明,否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时,应当明白,为了便于描述,附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论,但在适当情况下,所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中,任何具体值应被解释为仅仅是示例性的,而不是作为限制。因此,示例性实施例的其它示例可以具有不同的值。应注意到:相似的标号和字母在下面的附图中表示类似项,因此,一旦某一项在一个附图中被定义,则在随后的附图中不需要对其进行进一步讨论。
在本申请的描述中,需要理解的是,方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,在未作相反说明的情况下,这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作,因此不能理解为对本申请保护范围的限制;方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述,在这里可以使用空间相对术语,如“在……之上”、“在……上方”、“在……上表面”、“上面的”等,用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是,空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如,如果附图中的器件被倒置,则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而,示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位),并且对这里所使用的空间相对描述作出相应解释。
此外,需要说明的是,使用“第一”、“第二”等词语来限定零部件,仅仅是为了便于对相应零部件进行区别,如没有另行声明,上述词语并没有特殊含义,因此不能理解为对本申请保护范围的限制。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
