The invention relates to the technical field of fabric
dyeing and finishing, in particular to a splitting process for
modal and
cuprammonium rayon. The process comprises the following specific steps:a multifunctional
dyeing machine with small bath ratio is adopted for
processing and comprises a rack, a padder, a cloth guide roller I, a cloth guide roller II and a dye vat, wherein the padder is arranged at one end of the rack, the cloth guide roller I is arranged on the side, opposite to the padder, of the rack, the dye vat is arranged under the rack, a downwards concave
liquid storage grooveis formed in the bottom of the dye vat, and the cloth guide roller II is arranged in the
liquid storage groove; an acidic splitting solution is added to the
liquid storage groove and contains sulfuricacid with concentration of 5-10 g / L, fabric is processed by the multifunctional
dyeing machine at 80 DEG C for 60 min, and the bath ratio is 1:3. The multifunctional dyeing
machine with small bath ratio is adopted for splitting
processing and is low in rotation speed and tension, the fabric is in a loose state, and iron-shine marks and crease marks cannot be produced.
