摘要

PROBLEM TO BE SOLVED: To provide a method for washing hospital bedclothes, capable of removing chlorhexidine gluconate adhered to the hospital bedclothes to prevent the generation of stained marks due to a chlorine-based bleaching agent by preliminarily washing the hospital bedclothes with an aqueous solution containing a polybasic carboxylic acid or a hydroxycarboxylic acid and subsequently mainly washing the hospital bedclothes. ;SOLUTION: This method for washing hospital bedclothes comprises preliminarily washing the hospital bedclothes with an aqueous solution containing a polybasic carboxylic acid or a hydroxycarboxylic acid and subsequently mainly washing the hospital bedclothes with an aqueous solution containing a bleaching agent, an alkali builder and a detergent. The polybasic carboxylic acid includes oxalic acid, malonic acid and succinic acid, and the hydroxycarboxylic acid includes lactic acid, malic acid, tartaric acid and citric acid. The preliminary washing may be carried out with an aqueous solution containing both the polybasic carboxylic acid and the hydroxycarboxylic acid.;COPYRIGHT: (C)1999,JPO
