What kind of glue is used for non-woven fabrics? Firstly, it is necessary to consider which material the non-woven fabric will be bonded with. Secondly, it is also necessary to consider whether the selected glue is environmentally friendly. Glue that meets environmental protection requirements should be chosen.
Hot melt adhesive is a kind of plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature while its chemical properties remain unchanged. It is non-toxic, odorless and belongs to environmentally friendly chemical products. Therefore, from the perspective of environmental protection, environmentally friendly hot melt adhesives are preferentially recommended for non-woven fabrics.
There are many types of hot melt adhesives. When choosing hot melt adhesives, the type of the bonding material with non-woven fabrics should be fully considered. For example:
- When non-woven fabrics are bonded with the skin: Generally, patch products such as moxibustion patches and foot patches are of this bonding type. Since the glue will directly contact the skin, when choosing hot melt adhesives, products with low skin irritation and a low sensitization rate are required.
- When non-woven fabrics are bonded with plastics: The surface energy of plastics is relatively low, and they are relatively difficult to bond compared with other materials. It is necessary to choose hot melt adhesives with good wettability. The hot melt adhesives can penetrate into the interior of plastics, making the adhesion stronger.
- When non-woven fabrics are bonded with non-woven fabrics: The bonding of non-woven fabrics to each other is relatively easy, and general hot melt adhesives can meet the bonding requirements. Specifically, it is also necessary to make a choice according to the application of the product. For example, for steam eye masks, hot melt adhesives with a low odor should be chosen. If there are color requirements, hot melt adhesives that are light in color or transparent should be selected.
