The selection of adhesives for non-woven fabrics is actually quite broad. The focus of selection depends on which material the non-woven fabrics are bonded to. It is difficult to give a satisfactory answer if one simply asks "what glue is used to bond the non-woven fabric". However, judging from the current market conditions, the focus of non-woven fabric rubber is to ensure environmental protection. So, what kind of glue should be used for non-woven fabrics to be environmentally friendly?
Regardless of the premise of bonding the non-woven fabric with the material, the adhesive for non-woven fabrics can be basically divided into two types: spray adhesive and hot melt adhesive. Everyone is familiar with spray glue. Many people may not have heard of hot melt adhesive. Hot melt adhesive is a thermal adhesive. It is a stable solid at room temperature. It melts to a certain temperature and produces viscosity. At the same time, Can complete the bonding of materials. Compared with spray glue, hot melt adhesive has a very big advantage in environmental protection. Therefore, from the perspective of environmental protection, it is recommended to use hot melt adhesives for non-woven fabrics.
There are many types of hot-melt adhesives. Non-woven fabrics that use hot-melt adhesives as adhesives need to consider the type of material they are bonded to, because the compatibility of materials and hot-melt adhesives must be considered. In fact, according to experience, there are some cases to help you choose hot melt adhesives:
Bonding of non-woven fabrics and non-woven fabrics: The bonding of non-woven fabrics and non-woven fabrics is very simple, usually we can use pa type hot-melt adhesive mesh film;
Non-woven fabric and leather bonding: PA-type hot-melt adhesive mesh is also recommended for non-woven fabric and leather bonding;
Non-woven fabric and metal bonding: Considering the specificity of metal materials, it is recommended to use pes hot-melt adhesive film as the adhesive;
Non-woven fabric and sponge bonding: From the perspective of composite effect, it is recommended to use PA hot-melt adhesive film lamination; however, if the laminating equipment cannot reach the laminating temperature, you can use eva's low-temperature hot-melt adhesive film.
For the composite of nylon cloth materials, you can consider using tpu film or pa mesh film.
The selection of non-woven fabrics for hot melt adhesives can be selected by referring to the above. However, the above is only the first direction of selection and does not involve specific models. To determine the models, more detailed composite requirements As a reference.
