封端水性聚氨酯的制备及其对棉织物的防皱整理
Preparation and wrinkle resistant finishing on cotton fabric of blocked waterborne polyurethane
摘要
Abstract
The blocked waterborne polyurethane was synthesized from toluene diisocyanate (TDI), polypropylene glycol (PPG), dimethylolpropionic acid (DMPA) and ethyl methyl acetoxime (EMAO). The structure of product was characterized by Fourier transform infrared spectrometer (FTIR). The cotton fabric was finished by the emulsion prepared with the blocked waterborne polyurethane and the properties were tested. The results showed that the optimal finishing technology was two-dip-two-pad (120 g/L of finishing agent and 60% ~ 70% of pick-up) process, and was cured at 150 ℃ for 3 min. The wrinkle recovery angle of the treated cotton fabric was up to 168.15°, and the breaking strengths of warp direction and weft direction of the treated cotton fabric were 468.50 N and 384.32 N, respectively. The finished cotton fabric could also retain the good permeability of the original cotton fabric. The mechanism of enhancing the wrinkle resistance and strength of the blocked waterborne polyurethane were discussed according to the FTIR characteristic absorption of the untreated and treated fabric.关键词
