Abstract: This paper discusses the effects of the dosage, setting temperature, and setting time of formaldehyde-free easy-care finishing agent DM-3527 on the iron-free property of cottons. Results indicated that when the dosage of DM-3527 is 140 - 160 g/L, setting the cottons for 90 - 150 s at 150 - 160 ℃ are the best crease-resistance processes. In addition, adding a six-carbon three-proof finishing agent 6118N in DM-3527 can improve the waterproof effect of the fabric, and significantly increase the wrinkle recovery angle of the fabric.

Key words: cotton fabric; easy-care finishing; wrinkle recovery angle; waterproof, oil repellency, antifouling finishing agent
