The invention belongs to the technical field of
textile printing and
dyeing, and in particular relates to a high-elastic non-ironing finishing method for pure cotton fabric. The method includes the following steps: fabrics preparation, mercerized finish,
liquid ammonia finish, pre-
softening, applying of a moist crosslinking agent, pre-shrinkage, storage reaction, washing, stretching setting and second pre-shrinkage. A stenter is used for applying the moist crosslinking agent, the moist crosslinking agent comprises CMC, a catalyst, a
fiber protecting agent, a softener,
hydrochloric acid, and the rest of water. The temperature of a
drying room is controlled at 80 to 100 DEG C, the temperature of the fabric is controlled between 35 to 40 DEG C, the falling cloth
humidity is 6-8%, and the fabric is rolled at the falling position. The treated fabric has non-ironing level reaching the AATCC124 standard 4.0 or above of the U.S.A,
formaldehyde content below 75ppm, warp elasticity of 4% above the ASTM D3107-2011 standard, weft elastic elongation of 17% above the ASTM D3107 standard, and has ensured sewability and non-ironing performance.
