[0024] The preparation method of the above-mentioned burned-out knitted fabric comprises the following steps:
[0025] Step S1, alkali treatment: put the burnt fabric into a vat filled with a sodium hydroxide solution with a concentration of 20-30 g / L, undergo an alkali treatment at a temperature of 80-100°C for 40-80 minutes, and then wash it with water. neutralize;
[0026] Step S2, burn-out treatment: dye the burnt-out gray cloth treated with alkali through an overflow tank by double-bath dyeing method; use a flat screen printing process to scrape-print the burnt-out gray fabric on the dyed burnt-out gray cloth, Bake at a temperature of 110-120°C for 5-8 minutes until it is completely carbonized, then wash with water at a temperature of 40-50°C for 30-60 minutes, and finally dry to obtain the fabric.
[0027] As a preferred embodiment, in step S2, the water washing adopts a combination process of open-width water washing machine cleaning and in-cylinder cleaning, and biolo...
