Abstract:

In order to improve moisture management property of cotton fabrics, local hydrophobic finishing by printing to change the hydrophobic properties of the fabric surface was carried out. The influence of pattern (square, circle, cruciform, triangle and pentagram), ratio of hydrophobic area (20%, 40%, 50%, 60%, 80%, and 100%) and size of hydrophobic pattem on moisture absorption, desorption, water vapor permeability, wetting and washing resistance of cotton fabric were studied. It is found that when a square pattern is adopted , the ratio of hydrophobic area to the total area of cotton fabric was 50% with a appropriate size of hydrophobic pattem, cotton fabric would have good quick-dry property and the ratio of hydrophobic area to the total area of cotton fabric is 50% with a appropriate size of hydrophobic pattern, with little influence on moisture absorption of cotton fabrics. The finished cotton fabric has good quick-drying property, and at same time it keeps good moisture management property and has a good washing durability.

Key words: cotton fabric, moisture management, moisture desorption, water vapor permeability, hydrophobic finishing, hydrophobic pattern
