METHOD FOR PRODUCING MATERIAL FOR SHOE INSOLE AND SUPINATOR AND MATERIAL FOR SHOE INSOLE AND SUPINATOR Russian patent published in 2003 - IPC

FIELD: light industry, in particular, manufacture of shoe inner parts. SUBSTANCE: method involves forming material comprising two layers, one of layers being manufactured from fibrous cloth by mechanical process using mixture of linen fibers and shrinkable synthetic filaments, with synthetic filament content in fibrous cloth being 30-40 wt%; providing needle stitching of cloth at needle stitching density of 120-360 cm^-2, stitching depth of 3-6 mm, and other layer being manufactured from woven or nonwoven thermally secured cloth of non-shrinkable filaments; connecting said layers by needle stitching process at need stitching density of 50-200 cm^-2 and stitching depth of 3-7 mm; providing thermal treatment of material in heated air medium at temperature of 180-190 C to provide for shrinkage over area of 5-10%; impregnating material with copolymer aqueous dispersion or emulsion of 5,000-12,000 sN hardness, with following squeezing and drying at temperature of 100-120 C until binder content of 9-35% in material and calendaring at temperature of 80-130 C and under pressure of 6-12 atm. Aqueous dispersion or emulsion may comprise scent-aromatizer and fungicide. Material surface may be provided with special finish. Material for manufacture of shoe insole and upper layer of supinator is composed of two layers, one of layers being made of fibrous cloth including linen and shrinkable synthetic filaments used in an amount of 30-40 wt%, and second layer being composed of woven or nonwoven thermally secured fabric of non-shrinkable filaments. After thermal treatment, material has shrinkage area of 5-10%, after impregnation and drying procedures - binder copolymer content of 9-35% and after calendaring procedure - thickness of 2.5-5.0 mm. EFFECT: increased resistance to cyclic dynamic compression force resulting in keeping of initial thickness of material, improved comfort, improved heat-insulating and moisture-absorbing properties and fungi resistance. 10 cl, 1 tbl, 28 ex
