[0011] For the mixed sample, the specification of the cotton and polyester-nylon composite silk fabric is: JC32XT160D 128X81 57 / 58, the weight is 152g / ㎡, and it is dyed. Take the following steps:
[0012] Pre-treatment: using continuous pad dyeing equipment, including desizing, bleaching and other steps; in desizing, the concentration of caustic soda is 8-10g / L, the chelating dispersant cm-5 is 2g / L, and the wax removing agent WR is 4 g / L, refining agent 88ECO is 4 g / L; in oxygen bleaching, the concentration of hydrogen peroxide 100% is 5.5-6 g / L.
[0013] Setting: Set the pre-treated fabric. The setting process conditions are: the amount of stabilizer added is 6-8 g / L, the temperature is 200℃±1℃, and the time is 25 seconds-40 seconds.
[0014] Mercerizing: Mercerizing the fabric after pre-treatment and setting. The mercerizing process conditions are: the amount of caustic soda added is 180-190 g / L, and the time is 55 seconds-60 seconds.
[0015] Dyeing with disperse dyes under acid...
