Non-iron finish method for pure cotton or polyester fabrics

Abstract

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.

Description

technical field [0001] The invention provides a non-ironing finishing method for pure cotton or polyester-cotton fabric, which belongs to the technical field of textile printing and dyeing. Background technique [0002] With the increasing call of human society to return to nature, people's demand for natural fiber clothing fabrics and natural and synthetic fiber blended clothing fabrics is gradually increasing. Cotton, as one of the representatives of natural fibers, has natural and comfortable characteristics. Polyester cotton , as one of the representatives of natural and synthetic fiber blended fibers, it has the advantages of both the natural comfort of pure cotton and the high strength and washable effect of polyester fiber, so it is more and more favored by people, but cotton and polyester cotton The main disadvantage of cotton is that it is easy to wrinkle and shrink after washing; therefore, in order to improve this shortcoming, the anti-wrinkle finishing of pure co...
