Drag force reduction Characteristic swimming wear

摘要

PURPOSE:To obtain the subject swimsuit especially suitable for swimming race, having extremely excellent reducing properties of fluid resistance by applying Tomes effect, by coating the surface of yarn with an aqueous solution of a high-molecular weight straight-chain organic polymer. CONSTITUTION:The objective swimsuit obtained by coating the surface of yarn with an aqueous solution of a straight-chain organic polymer (preferably polyethylene oxide) having 200,000-500,000mol.wt. The concentration of the aqueous solution is preferably set =10ppm as concentration to cause 35% friction reduction ratio at 40rps of rotary disc.
