METHOD OF PRODUCING MOISTURE PERMEABLE LAMINATE SHEET, HOT-MELT ADHESIVE COMPOSITION FOR THE MOISTURE-PERMEABLE LAMINATE SHEET, AND MOISTURE PERMEABLE LAMINATE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a moisture permeable laminate sheet having waterproof property, weather resistance, and heat resistance by laminating a microporous polyolefin film having moisture permeability and various kinds of substrates (nonwoven fabric, woven fabric, cut fabric, mesh, net, felt, paper, and cloth or the like) having breathability by using a hot-melt adhesive, and the hot-melt adhesive preferably used for laminating.;SOLUTION: The adhesive is characterized in that the microporous polyolefin film and a breathable substrate are bonded by using the hot-melt adhesive containing a styrene block copolymer where melt viscosity is 100,000 mPa s or more at the temperature of 90°C measured under a specific condition in a melting state where the melt viscosity is under the condition is 50,000 mPa s or less.;COPYRIGHT: (C)2009,JPO&INPIT
