Abstract: Using coating method, pigment dyeing, water-and oil-repellent and flame retardant finishing is carried out on pure cotton canvas in one bath.The influences of the coating formula and process conditions of the one bath coating method on composite functional coating were studied. The morphology, surface elements and thermal properties of fiber were characterized by Scanning electron microscopy (SEM), X-ray energy spectrum analysis (XPS) and thermoanalysis (TG).The cotton canvas after coating in one bath have water-and oil-repellent more than 4 grade, Water-pressure Resistance more than 180 cm, flame retardancy of B1, color fastness to wet rubbing of 4 grade. The results showed that the fluoride and phosphorus of fiber significantly increased. There are also three cracking stage after composite functional coating, but each phase of the temperature is decreased obviously, especially the main stage, and residue quantity is obviously improved.
