Antifouling finishing with fluorinated polyurethane on cotton fabric
摘要
Abstract
In order to solve the problem of easy contamination of textile, cotton fabric was finished by an-tifouling fluorinated polyurethane by the method of impregnation, and the finishing process was explored. The optimal finishing process was that the dosage of fluorinated polyurethane was 30% and the curing time was 60 s. The water contact angle (CA) of antifouling fabric was 158.0°, oil- repellent grade was 8 and antifouling grade was 4~5. The fabric exhibited excellent antifouling performance, which presented excellent protective ability to various infectants in daily life like orange juice, sauce and capisol. The finished fabric had acid and al-kali resistance, especially when the pH was 3~11, the water CA was higher than 150.0°. Besides, the cotton fabric maintained good antifouling property when the temperature range was between- 10 ℃ and 150 ℃. The treated cotton fabric owned strong abrasion resistance. After 600 times friction, the CA maintained 150.2°, the oil- repellent grade was 8 and the antifouling grade was 4~5.And the abrasion resistance was excellent.关键词
