In order to investigate the contraction variation of an N/P (nylon/polyester) microfiber woven fabric wiper, optimal mixing ratio of surfactants and solvents were investigated. Four kinds of solvents including four anionic surfactants and seven nonionic surfactants were assessed for the best contraction characteristics of the fabrics. Emulsifying capacity, foaming capacity, and contraction power were measured and the optimal solution mixing ratio was selected. When the optimal mixing ratio of 36:54:60:850 was used in regards to aryl ethoxylate sulfate, EO/PO copolymer, methoxy propanol and benzyl alcohol, the contraction power of the fabric was obtained in terms of emulsifying capacity, foaming property and recyclability.
