Method for integrating multi-layer sheet fabric pieces for use in a chemical protective suit

Abstract

[Object of the Invention] An object of the present invention is to provide a method for integrating multi-layer sheet fabric pieces for use in a chemical protective suit, wherein fewer fabrication man-hours are required than in the conventional method. [Disclosure of the Invention] A method for integrating multi-layer sheet fabric pieces for use in a chemical protective suit comprises the steps of (a) stacking one of a pair of multi-layer sheet fabric pieces for use in a chemical protective suit, each of which comprises a front surface layer of thermoplastic resin film, a rear surface layer of thermoplastic resin film, and at least one middle layer of chemical permeability resistant resin film, on the other of the pair of multi-layer sheet fabric pieces, with a part of a peripheral edge of one multi-layer sheet fabric piece opposed to a part of a peripheral edge of the other multi-layer sheet fabric piece, (b) seaming the stacked multi-layer sheet fabric pieces at a portion close to the peripheral edges opposed to each other along the peripheral edges opposed to each other so as to form a seam line, and (c) high frequency dielectric heating the stacked multi-layer sheet fabric pieces at a band portion of predetermined breadth close to the seam line along the seam line, wherein the peripheral edges opposed to each other and the band portion are disposed to face opposite sides of the seam line, so as to weld and integrate the stacked multi-layer sheet fabric pieces with each other at the band portion.
