[Chemical 1] [However, n represents an integer of 4 to 7] In order to improve washing durability, Japanese Patent Publication No. 61-4544.
As described in JP-A-1 and JP-B-62-60509, there has been proposed a method of fixing a polyhexamethylene biguanide compound after treating a fiber with a polyacrylate or an anion group-containing polymer. However, since this method requires pretreatment, the cost of the manufacturing process is high, and further improvement has been required. Further, as described in JP-A-3-39310, there is also a method of preparing a processing emulsion by previously copolymerizing a polyhexamethylene biguanide compound, a sulfone group-containing monomer and an acrylate ester. The method also requires a polymerization step, which is a pre-reaction when preparing the processing agent, so that preparation of the processing agent is time-consuming and costly.
