FIELD: textile, paper. ^ SUBSTANCE: method for formation of waterproof filar joint consists in application of sealant onto shuttle thread, closing segments of garments by shuttle stitching and curing. Sealant is represented by aqueous solution of acrylic lightly crosslinked thickener and self-cross-linking binding preparation with concentration of 40-80%. When interacting with water, chemical composition swells, increasing in volume, and after drying it returns into initial volume state, which provides for high hygienic properties of clothes due to change in water impermeability of filar joints as ambient humidity changes. ^ EFFECT: composition binds large amount of water, in process of thermal treatment it produces spatial net structure, which pierces chains of acrylic thickener and provides for adhesion of polymer film to fibre of sewing thread. ^ 2 dwg, 2 tbl, 3 ex |
