Description

TECHNICAL FIELD [0001] The present invention relates to a multilayer breathable waterproof film laminate having a breathable thermoplastic hot-melt adhesive layer and a method for producing the multilayer breathable waterproof film laminate. [0002] MOISTURE-

The present invention relates to a multilayer breathable and waterproof film laminate having a breathable thermoplastic hot-melt adhesive layer and a method of manufacturing the multilayer breathable waterproof film laminate. More particularly, the present invention relates to a multilayer breathable waterproof film laminate having a breathable thermoplastic hot- The present invention relates to a multilayer breathable waterproof film laminate having a breathable thermoplastic hot-melt adhesive layer capable of providing a fragrance-dissipating function for a long period of time when applied to a product employed in a human body, and a method for manufacturing the multilayer breathable waterproof film laminate.

Sports wear such as shoes and mountaineering clothes such as hiking boots and running shoes are generally required to have excellent breathability and waterproofness in addition to activity and light weight at the time of wearing.

"Waterproof and breathable" refers to the property of passing water droplets, such as water vapor, which does not pass water but evaporates sweat and water droplets. The principle of obtaining such "moisture permeability" and "waterproofness" is that the size of water vapor and the size of water droplets (the diameter of water droplets is 1 mm or more and the diameter of water vapor is 0.0004 μm or less) Is formed on the surface of the fabric, water vapor or carbon dioxide molecules coming out from the skin are emitted to the outside through the space between the fibers and the water droplets can not penetrate into the inside.

As a technical method for manufacturing such a moisture-proof foam, there are a method of processing a high-density fabric using ultrafine fibers, a method of laminating a fine porous film to a fabric, or a method of coating a moisture-permeable and waterproof resin directly. Among these, the most active research result in the production of moisture-proof tarpaulins is that a resin is coated on a release paper to prepare a hydrophilic non-porous or porous film, and then this is laminated with a fabric with an adhesive to produce a moisture-proof tarpaulin. In this case, there are two methods of bonding, dot bonding and front bonding, but dot bonding is mainly used for products requiring high functionality (high moisture permeability, soft touch).

In a laminate in which a plurality of substrates are laminated by the dot-to-line bonding method, the contact strength between the substrate and the adhesive is usually very small, so that sufficient sufficient bonding strength can not be maintained (normal state) . Particularly, when clothes or the like prepared by the above method are washed with water, the adhesive strength of the adhesive significantly decreases due to the influence of water or a detergent, and as a result, peeling between the substrates occurs.
