Non-iron finish method for pure cotton or polyester fabrics

The invention provides a non-iron finish method for pure cotton or polyester fabrics. The non-iron finish method for pure cotton or polyester fabrics is characterized in that the technological processes sequentially include fabric preparing, liquid ammonia finishing, acid washing, pre-softening, preshrinking, moist crosslinking agent applying through a foaming machine, storage reacting, washing, tentering and forming, preshrinking and inspecting and packaging; the concentration of an acid catalyst MC1 in auxiliaries for the acid washing process is 50g/l, the pH valve of a cloth cover is controlled to be 4-5, and the cloth cover is then subjected to alkaline neutralization to control the pH value to be 6-7; and the foaming machine is used to apply a moist crosslinking agent, the moist crosslinking agent comprises the following components according to weight ratio: 220-260g/l of resin carboxymethyl cellulose (CMC), 110-130g/l of catalyst MC1, 20-30g/l of fiber protective agent HDP, 10-30g/l of softening agent RPU-N, 1-2g/l of hydrochloric acid and the balance of water, the temperature of a drying room is controlled between 80-100 DEG C, the temperature of the cloth cover is controlled between 35-40 DEG C, the humidity of a doffing is between 6-8%, and finally, the fabrics are wound on the doffing.
