Liquid-impermeable stitching method for seam of vapor-permeable virus-barrier fabric

A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.
