Application of fluorine free waterproofing agent X-702M on chemical fiber fabrics after washing and drying
The waterproof performance of a fluorine free polyurethane waterproof agent X-702M on chemical fiber fabrics after washing and drying was studied.The hand scratches on the fabric treated with X-702M were relatively light and had a soft feeling.The influence of different crosslinking agents on the water-proof performance of washed and air dried products was explored.It was found that the waterproof perfor-mance of the crosslinking agent AX-101Z after washing and drying was better.When the dosage of X-702M was 50 g/L and the dosage of AX-101Z was 10 g/L,the fabric had good waterproof performance,waterproof performance after washing and drying,hand scratches,and feeling.It could achieve an initial waterproof perfor-mance of level 5(100 points)on synthetic fiber fabrics,and after 5 washing,the waterproof performance of air dried reached level 3-4(80-90 points)at a room temperature.
