一种环保棕麻垫生产工艺
技术领域
本发明涉及棕麻垫技术领域,特别是涉及一种环保棕麻垫生产工艺。
背景技术
棕麻垫是一种利用棕纤维和麻纤维进行混合铺网和轧制的植物垫,材料来源广泛,而且无毒环保,在床垫和坐垫领域使用比较普遍。棕麻垫表面较为粗糙,柔软性差,无法满足人们对床垫和坐垫日益增长的高要求。
为了提升棕麻垫的功能性,市场上的部分棕麻垫在表面进行了包装,通过增加其他功能层进行复合,来增加对应的功能,满足市场的需要。在生产过程中,功能层的复合通常需要涂抹胶水,不够环保,而且由于棕麻垫表面并不平整,涂胶厚度均匀性差,降低了质量稳定性和成品率,而且胶水固化后形成屏障,降低了棕麻垫的透气性,需要改进。
发明内容
本发明主要解决的技术问题是提供一种环保棕麻垫生产工艺,提升生产的保护性和成品率,确保棕麻垫产品质量的稳定性和透气性。
为解决上述技术问题,本发明采用的一个技术方案是:提供一种环保棕麻垫生产工艺,包括以下步骤:
备料:准备垫芯层的原料,垫芯层的原料包括椰棕纤维和麻纤维;
垫芯层的成网:根据工艺要求进行垫芯层原料的称重,然后导入开松机进行开松混合,然后梳理及气流成网,得到垫芯层;
粘合层的加工:采用热熔胶膜作为粘合层,进行热熔胶膜的放卷,并利用打孔机在热熔胶膜上打孔,得到数列通孔;
复合:将打孔后的热熔胶膜贴合在表层的底面,再随表层复合在垫芯层上,送入烘箱进行加热,加热到120~160℃的温度后保温4~6分钟,然后压制和冷却成型。
在本发明一个较佳实施例中,所述垫芯层的原料还包括热熔纤维。
在本发明一个较佳实施例中,所述热熔纤维在垫芯层的原料中的重量份为1~10重量份。
在本发明一个较佳实施例中,所述垫芯层的原料中包括50~80重量份的椰棕纤维以及20~50重量份的麻纤维。
在本发明一个较佳实施例中,所述复合步骤中,加热到130℃的温度后保温4分钟。
在本发明一个较佳实施例中,所述表层采用无纺布、乳胶垫、毛毡、三明治面料或者纺织面料中的至少一种。
在本发明一个较佳实施例中,所述粘合层的加工步骤中,在热熔胶膜上打孔得到的片状热熔胶膜残料进行收集,待到复合步骤时,将片状热熔胶膜残料间隔排布在垫芯层表面的边缘。
本发明的有益效果是:本发明指出的一种环保棕麻垫生产工艺,特别设计了粘合层的加工步骤,利用打孔机在热熔胶膜上打孔,既能确保复合后的结构稳定性和透气性,还能提升生产过程的环保性,提升了成品率。
