[0007] The process flow is:
[0008] 1. Fabric preparation: The process of fabric preparation: the front and back of the fabric should be the same when sewing, the seam should be straight and firm, the singeing process requires singeing clean, the desizing process requires clean desizing, and the desizing rate is 98% Above, in order to ensure the non-ironing effect and hand feeling, the alkali mercerizing requires sufficient mercerization, the pH value of the cloth surface is between 7-8, after liquid ammonia finishing, add 1.5g / L of acetic acid in the last tank of the liquid ammonia washing equipment, and the fabric The PH value is adjusted between 5-6 so that the resin can fully chemically react during the non-iron finishing.
[0009] 2. Pre-softening: It is carried out on a tenter, the composition and weight ratio are: pre-softening agent UFH 30g / L, acetic acid 1.5g / L, the rest is water, the drying room temperature is controlled at 90℃, and the cloth surface humidity is control...
