The CN105350286B patent discloses a processing method of natural non-ironing pure cotton fabric, which comprises the following steps: selecting yarn → dyeing yarn → sizing → weaving → singeing → desizing → mercerizing → liquid ammonia → biological enzyme treatment → drying → non-ironing resin finishing → preshrinking, wherein in the step of dyeing, the non-ironing resin finishing liquid comprises 0.1-0.5g/L of glacial acetic acid, 100-150g/L of organic silicon resin, 20-40g/L of cross-linking agent and 30-40g/L of softening agent, and the processed fabric has very smooth and soft hand feel, so that the yarn-dyed pure cotton non-ironing fabric is obtained.
The CN111851076A patent discloses improving the wool effect of the fabric after resin finishing. The processing method of the water absorption comprises the steps of sequentially singeing pure cotton grey cloth → desizing → oxygen bleaching → mercerizing → dyeing → liquid ammonia → non-ironing → baking → washing → softening → preshrinking, wherein the non-ironing liquid is a mixed liquid of non-ironing resin CR-E80-130 g/L, resin catalyst CT-C24-39 g/L, fiber protective agent 10-30g/L, resin synergist 10-30g/L, penetrant MRZ1-3 g/L and super-hydrophilic auxiliary agent 10-20g/L, and the pure cotton grey cloth is dyed and then is non-ironing, and the non-ironing property of the fabric finished by the method reaches above 3.2 level.
CN103437212A discloses a washing and dyeing process for casual clothes, which comprises the steps of selecting ready-made clothes, dyeing, washing, post-processing and the like, wherein the post-processing comprises non-ironing finishing and ready-made clothes packaging, and the non-ironing process comprises the steps of washing with a catalyst of 60-80g/L, dewatering, ironing cloth, drying and non-ironing. The process shortens the processing procedure of washing, dyeing and leisure clothes, saves energy, adjusts the non-ironing efficiency of the ready-made clothes, has long time use compared with the non-ironing efficiency of fabrics, and has stiff hand feeling of the ready-made clothes.
