When HMPSA for non-woven fabrics are bonded with other materials, they need to be bonded with glue. When using glue, we should first consider which material to use.
Secondly, we should also consider whether the selected glue is environmentally friendly and choose the glue that meets the requirements of environmental protection.
Hot melt pressure sensitive adhesive is a kind of plastic adhesive. It is non-toxic and tasteless. This is an environmentally friendly chemical product.
Therefore, from the perspective of environmental protection, hot-melt pressure-sensitive adhesive is the first choice for non-woven fabrics.
Characteristic
There are many kinds of hot-melt pressure-sensitive adhesives. When selecting hot melt adhesive, the type of bonding material should be fully considered.
Adhesion to skin: this type of adhesion is usually used in patch products, such as Aiwu patch and foot patch, because the adhesive will come into direct contact with the skin.
When selecting hot melt adhesive, products with low skin irritation and low sensitization rate are required.
Bonding with plastics: compared with other materials, the surface energy of plastics is relatively low and difficult to bond.
We need to choose the hot melt adhesive with good wettability. Hot melt adhesive can penetrate into plastics and has stronger viscosity.
Non woven fabric bonding: the bonding between non-woven fabrics is relatively easy, and the general hot melt adhesive can meet the bonding requirements. It also needs to be selected according to the application of the product.
For example, the steam eye mask needs to choose low odor hot melt adhesive, and the color needs to choose light color or transparent hot melt adhesive.
Application
HMPSA for non-woven fabrics are suitable for agricultural film, shoe making, leather making, mattress, quilt, decoration, chemical industry, printing, automobile, building materials, furniture and other industries.
And clothing lining, medical and sanitary disposable surgical clothes, masks, hats, bed sheets, etc.
