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.
