Without considering the material bonding of the non-woven fabric, the adhesive for the bonding of the non-woven fabric can basically be 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. Can complete the bonding of materials. Compared with spray glue, hot-melt adhesive has a great advantage in environmental protection. Therefore, from the perspective of environmental protection, it is recommended to use hot melt adhesive 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:
• Non-woven and non-woven bonding: Non-woven and non-woven bonding 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 hot-melt adhesive film of pes material as the adhesive;
• Non-woven fabric and sponge bonding: From the perspective of composite effect, it is recommended to use PA hot-melt adhesive mesh film composite; however, if the composite equipment cannot reach the composite temperature, eva's low-temperature hot-melt adhesive mesh film can be used instead.
• TPU film or PA mesh film can be considered for the composite of nylon cloth materials.
The selection of hot melt adhesives for non-woven fabrics 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 are required. For reference.
