Hot melt is very useful for many things. Hot Melt is used as a leakage resistant and self-adhesive. Coating provides to waste barrier. It is a portion of the non woven with a hot melt adhesive to deposit a liquid impermeable film there on. Generally, different types of functions will be performed the hot melt adhesive in addition to serving as a waste barrier. On the side of nonwoven which will not come into direct contact with the absorbent core. If the hotel melt is formulated to be pressure sensitive it could be utilized.
The nonwoven side is directly contact the core, the hot melt adhesive coating serves not only as a waste barrier but also aid in construction to position any super absorbent powders or films used, the migration of which is presently difficult to prevent using conventional techniques. A dual function of securing as well as of preventing leakage is served by the hot melt adhesive from the core. In this procedure, no reduction in manufacturing line speeds. Curing or drying is not required because it is not a saturant but rather a coating. It is only applied to the interior surface of the nonwoven. It is not come in contact with the skin.
