As the non-ironing finishing agent may contain N-methylol compounds, formaldehyde is inevitably generated in the production process, a small amount of urea or other substances can be added to absorb the formaldehyde, and if the urea is excessively used, the cloth cover is yellow. Other non-permanent press finishes that do not produce formaldehyde can be used. In addition, under the acidic catalysis condition, the modified graphene nylon fiber is easy to denature again, the fabric is required to be in an acidic environment for a short time of 5-15s, in order to prevent the surface resin from being formed due to migration of the non-ironing finishing agent during pre-drying or free formaldehyde from being generated due to self-crosslinking of part of the resin, the setting temperature is not too high, and 7-8 of the discharged cloth is guaranteed to be dry. Meanwhile, a small amount of penetrating agent can be added to ensure that the resin can fully penetrate into the fabric.
