Abstract
Abstract A cloth suitable for ink-Jet textile printing is mainly composed of cellulosic fibers having an average fiber length of 25 to 60 mm, the cloth having a moisture regain of 13.5 to 108.5%. The cloth may be mainly composed of cellulosic fibers having an average thickness of 0.6 to 2.2 d and an average natural twist of 70 to 150/cm, or mainly composed of regenerated cellulosic fibers. In an ink-jet textile-printing method, a textile printing ink is imparted to the cloth, and then a dyeing process is conducted, followed by a washing process.
