The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a processing technology of warp-elastic and weft cotton high non-ironing warp and weft double-elastic fabric. Spandex elastic yarn is used for the warp yarn, and pure cotton is used for the weft yarn; the processing process includes the following steps: weaving-design-singeing-descouring-scouring-oxygen bleaching-dry setting-mercerizing-liquid ammonia-whitening-iron-free-softening. Adopting the process of the present invention can reduce the strength reduction of the fabric, so that the appearance of the non-ironing property after 5 washes under the AATCC 124 method can reach level 3.5 or above. More than 15%, the fabric of the present invention is soft and comfortable to wear, has the characteristics of high non-ironing property, high recovery property and the like.

The present invention provides a finishing method for warp and weft double-core-spun elastic non-ironing fabrics, which is characterized in that: the warp yarn uses pure cotton 11.7tex, the weft yarn uses pure cotton 14.5tex to cover low-elastic network yarn 105D and spandex elastic yarn 70D, The mass ratio of the three is that pure cotton accounts for 90% to 95%, low elastic network yarn accounts for 5% to 8%, and spandex elastic yarn accounts for 2% to 5%. The technological process is steamed yarn, weaving, turning cloth, burning Wool, desizing, scouring, bleaching, mercerizing, liquid ammonia, moisture crosslinking, stacking, washing, tentering, pre-shrinking and inspection; the yarn is steamed by high-temperature steam to release part of the stress of the spandex elastic yarn, dyeing In the whole process, there is no processing and dry setting, which can improve the problems of fabric yellowing, low elasticity, curling, etc., and through the moisture cross-linking finishing technology, the appearance of the fabric after 30 times of washing under the AATCC 124 method can reach above 3.5, and the elasticity is in ASTM D3107 ‑2011 method can reach more than 20%. The fabric treated by the invention is soft and comfortable to wear, moderate in elasticity, good in recovery, and has excellent non-ironing effect.

The invention discloses a non-iron crease-resistant finishing agent of formaldehyde-free cellulose fabrics and a preparation method thereof, aiming at the problem that the prior non-iron crease-resistant finishing agent has high requirements for the raw materials used for synthesis or has no ideal non-iron effect and firmness on the fabrics. The non-iron crease-resistant finishing agent is composed of unsaturated acid monomer and acrylate that are polymerized in aqueous phase under the actions of initiator, regulator and catalyst, the regulator is convenient for performing penetration and esterification cross-link reaction, and has good cross-link effect, the catalyst has good catalyzing effect and complete reaction. The non-iron crease-resistant finishing agent has the advantages of outstanding non-ironing crease-resistance performance, less yellowing and higher strength reservation.
