Non woven materials can be easily bonded together with hot melt adhesive. Glue Machinery recently demonstrated this successful process to a customer wanting a quick, strong, and effective bond of these kinds of materials.

The Champ 3 with Slot Die is used to apply a thin flat pattern of hot melt adhesive for bonding nonwoven materials to other nonwoven material.

For this application, manually tilt the Champ 3 so that the Slot Die nozzle is at a 30 degree angle relative to the substrate, depress the piston pump trigger, and finally move the gun across the substrate to apply a thin pattern.

It is recommended that you use a hot melt with a long open time and medium viscosity to insure that you have ample assembly time. This also ensures that the adhesive does not migrate too deeply or through the porous non-woven material.

Please note that other application methods can be used to bond non woven materials. (Click here for video of another example) Contact Pierce Covert at Glue Machinery Corporation to discuss your particular needs and wide range of options we have to offer.
