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.
