The fabrics treated with this compound showed good oil repellent and moderate water repellent properties： the oil repellent rating and the water repellent score were 6 and 80 respectively. Even after 10 washing cycles, the repellent properties were kept at the same level. The finished fabrics also showed some wrinkle-resistant properties, and the dry wrinkle recovery angle was increased by 53° compared with untreated fabrics. The critical surface energy of the treated fabric surface was 20±1 mN/m. This multifunctional compound also showed good water solubility, which would be beneficial for the environmental protection.展开更多
