Description
技术领域
本发明涉及卫生用品的技术领域,具体是一种透气性较好的卫生用品。
背景技术
现有的卫生用品的吸水层(也称吸收层)的吸水芯体卷材制作工艺:依次铺设第一层无尘纸,第二层高分子吸水颗粒(可选SAP、SAF等)层,第三层蓬松无纺布,第四层高分子吸水颗粒,第五层无尘纸(具体可参考中国专利文献CN208693620U)。
现有的卫生用品的吸收体的芯体多采用高分子吸水颗粒加绒毛浆的组合,比较容易断层,且透气性较差。如何提高吸收体的透气性,以提升用户的使用舒适度、避免细菌滋生,是本领域要解决的技术问题。
发明内容
本发明所要解决的技术问题是提供一种结构简单、透气性较好的卫生用品。
为了解决上述问题,本发明提供了一种透气性较好的卫生用品,包括用于吸收液体的吸水层,吸水层包括吸收芯体片层,该吸收芯体片层由多个条形体相间排列而成。其中,所述条形体相间设置,形成的间隙利于透气,进而升用户的使用舒适度、避免细菌滋生。
为了避免条形体中的高分子吸水颗粒泄漏,所述吸水层还包括设于所述吸收芯体片层两侧的无尘纸或无纺布。
具体实施时,所述吸收芯体片层采用吸收芯体卷材分切而成,以利于提高生产效率。
优选的方案是,所述的多个条形体平行排列且与卫生用品的折叠中心线平行或垂直,尤其是用于乳垫时,各条形体与卫生用品的折叠中心线平行,使用时使乳垫的折叠中心线呈基本水平状态,则各条形体起到挡水条的作用,提升吸水效果。
所述防水层包括一层或多层叠层分布的熔喷布,以及贴合在该熔喷布下侧的纺粘无纺布;所述纺粘无纺布的克重为15-30g/㎡,所述熔喷布的克重为20-45g/㎡。
所述纺粘无纺布通过点状分布的胶粘接在该熔喷布的下侧面上,或所述纺粘无纺布采用点状分布的超声波焊接、热融接的方式连接在该熔喷布的下侧面上。
所述顶片的中央设有水胶体敷料。
进一步,所述卫生用品为乳垫、汗垫、卫生巾或尿不湿;所述乳垫包括依次叠层设置的用于液体渗透的顶片、用于吸收液体的吸水层和用于防止液体渗透的底片,所述顶片和底片的外缘相连。所述吸收芯体片层的邻近所述顶片的一侧设有透水材料层(可选无尘纸、无纺布等),所述吸收芯体片层的邻近所述底片的一侧设有透水材料层或防水材料层(可选拒水无纺布)。
所述顶片或吸水层的中部设有水胶体敷料。水胶体敷料是由弹性的聚合水凝胶与合成橡胶和粘性物混合加工而成的敷料。敷料中最常见的凝胶为羟甲基纤维素,该凝胶可牢固地粘贴于创口边缘皮肤,当吸收渗液后可膨胀12倍。水胶体敷料含有以下特性:1、具有吸收创面渗液的能力。吸收渗液后,敷料中的亲水性颗粒可形成类似凝胶的半固体物质,附着于伤口基部,提供并维持有利于创面愈合的湿性环境。2、有粘性,可形成密闭创面。密闭的愈合环境能够促进微血管的增生和肉芽组织的形成,从而加速创面愈合。3、可发挥清创功能。一方面,水胶体含有内源性的酶,能促进纤维蛋白的溶解;另一方面,水胶体敷料所提供的密闭环境,有利于巨噬细胞清除坏死组织。水胶体敷料是在湿性愈合原理指导下发展起来的一类新型伤口敷料。水胶体敷料可应用于多种不同伤口的治疗,特别是对于慢性难愈性伤口具有显著疗效。水胶体的吸收性、粘性等特点,使其达到理想敷料的基本要求,即保护伤口、提供促进伤口愈合的适宜环境和易于移除且不损伤新生组织。当然水胶体敷料仍具有再发展的空间,如提高吸收性和增强抗菌能力等。
本发明的技术效果:(1)本发明的卫生用品中的吸收芯体片层由多个条形体相间排列而成。所述条形体相间设置,形成的间隙利于透气,进而升用户的使用舒适度、避免细菌滋生。(2)顶片的中部设有水胶体敷料,使用时与乳头相对设置,水胶体敷料能减轻破损乳头的症状、利于乳头愈合。()3)防水层(也即底片)为熔喷布,熔喷布克重小、柔性好、拒水效果好,并可阻挡细菌,其透气性远好于透气塑料膜和拒水无纺布,大幅提升了产品使用舒适度;(4)纺粘无纺布通过点状分布的胶粘接在该熔喷布下侧面上,以利于产品外侧面上胶。
