White nylon printed cloth and preparation process thereof

The invention provides a bleached nylon printed fabric and a preparation process thereof, the preparation process comprises the steps of high-temperature blank fixing, printing, ageing and washing on a nylon fabric in sequence, and slurry for high-temperature blank fixing contains a fluorescent whitening agent; the fluorescent whitening agent is added into the sizing agent for high-temperature blank fixing, the sizing agent can directly react with the nylon cloth in a machine head sizing agent tank through a pipeline, the bleaching effect on the nylon cloth can be improved, and then the subsequent printing effect is better; the preparation process is simple in process, the production cost can be greatly reduced, the production period is shortened, meanwhile, turnover and pulling in a dye vat are omitted, the risk of creases is greatly reduced, energy consumption is greatly reduced, and carbon emission is reduced. 本发明提供一种漂白色的尼龙印花布及其制备工艺，所述制备工艺包括对尼龙布依次进行高温定胚、印花、蒸化和水洗的步骤，所述高温定胚的浆料中包含荧光增白剂；本发明通过在所述高温定胚的浆料中添加荧光增白剂
