[0014] CVC20X20 90X50 67''polyester cotton blended fabric.
[0015] The production method adopted sequentially includes gray cloth manufacturing, gray cloth turning, gray cloth singeing, desizing, shaping, dyeing, pre-shrinking, and inspection procedures. After the desizing process and before the shaping process, there is a loose mercerizing process. After the dyeing process and before the pre-shrinking process, there is a loose rolling process.
[0016] In the gray cloth singeing process, the front and back sides are burnt once, the vehicle speed is 110 m / min, and the width is reduced by 3 cm after singeing; In the slurry, the amount of caustic soda is 32g / L, and the rest is water. In the hydrogen peroxide desizing solution, the amount of hydrogen peroxide is 8g / L, and the rest is water. First use caustic soda and then hydrogen peroxide for desizing. The gross effect after desizing is 11 cm / L In 30 minutes, the whiteness was 73, and the width was reduced by 10%; in the pine-...
