DESIGN OF HEAT-INSULATING SLEEVE PACKET OF HEAT-PROOFING CLOTHES WITH UNLINKED HEAT INSULATION MATERIAL Russian patent published in 2009 - IPC A41D27/10 A41D31/00 

FIELD: personal demand items.

SUBSTANCE: design of heat-insulating sleeve packet of heat-proofing clothes with unlinked heat-insulation material comprises external and internal layers of shell, unlinked heat-insulation material installed between them, areas of layers fixation along part contour, areas of layers fixation by quilt stitches or welding lines. Prior to packet quilting, external and internal layers of shell materials are fixed with quilting stitch along the line of front roll of sleeve, which separates heat-proofing packet into two adjacent compartments for filling with unlinked heat-insulation material. Density of unlinked heat-insulation material density for lower part of sleeve is less than density of unlinked heat-insulation material for upper part of sleeve.

EFFECT: invention provides for arrangement of sleeve design, which has smooth surface with static position of naturally dropped hand in external side of sleeve and touches body panel of item at internal side of sleeve, stable structure in process of operation, and also reduced specific consumption of heat-insulation material with specified level of thermal resistance.
