无纺布在生产时是没有其他附着加工工艺的，为了产品需要可能要求材料多样化和一些特殊的功能，就会加工无纺布原材料上，根据加工模式的不同产生了不同的工艺，像无纺布的覆膜和淋膜就是无纺布比较常见的工艺。
Non-woven fabrics have no other adhesion processing technology in production. In order to meet the needs of products, it may require material diversification and some special functions. It will process raw materials of non-woven fabrics. According to different processing modes, different processes have been produced, such as film covering and film showering of non-woven fabrics, which are common processes of non-woven fabrics.
覆膜无纺布与淋膜无纺布到底有什么区别呢?
What is the difference between coated nonwovens and showered nonwovens?
第一：无纺布的淋膜就是用专业的机器把塑料加热成液体，再通过机器把这些塑料液体浇在无纺布的一面或者双面，机器的一边有烘干系统，可以把这一层浇好的塑料液体烘干冷却，这样就生产出淋膜无纺布了。
First: Non-woven Fabric Shower film is to use professional machines to heat plastic into liquid, and then pour these plastic liquids on one side or both sides of the non-woven fabric through the machine. On one side of the machine, there is a drying system, which can dry and cool this layer of plastic liquid, so as to produce non-woven fabric shower film.
第二：无纺布的覆膜是用无纺布覆膜机，通过这台先进的大型机器把买来的成卷的塑料薄膜直接和无纺布的材料复合在一起，就成了覆膜无纺布了。 可以看出无纺布的覆膜和淋膜的不同就在于，生产工艺和原材料的不同，生产出的成品外观和作用基本原理一样的。
Secondly, non-woven fabric is covered by non-woven film machine, through this advanced large-scale machine to buy rolls of plastic film directly and non-woven materials together, it becomes a film-covered non-woven fabric. It can be seen that the difference between coating and spraying of non-woven fabrics lies in the difference of production process and raw materials, and the appearance and basic principle of the finished products are the same.
