1.1 White cloth roll preparation, gray cloth after pretreatment, mercerizing, stretching and winding to form a certain size of white cloth roll, used for roll wax printing. In order to ensure the quality of wax film, improve the brightness, depth and uniformity of low-temperature dyeing of waxed cloth, and prevent cloth breakage from affecting production efficiency, white cloth roll should meet the following requirements:
(1) The fixed gate width is 120 cm, the shrinkage rate is 2.5%, and the fixed gate width is used in subsequent processing.
(2) Whiteness 85, capillary effect 14 cm/30 min, mercerized barium 140, strength damage less than 5%, weight loss less than 8%, weft slope less than 2 cm;
(3) The tidal content is uniform and controlled at 7%.
