Synthetic fibre textile dyeing color fastness first uses graphene quantum dot dispersion to handle terylene, then uses at graphene dispersing solution again
Reason promotes reduction with obvious effects to dacron dyeing color fastness, it can be seen that, the present invention is to polyester modified treatment process steps
Secondary sequence is stronger, the terylene after modification, stronger with being combined property of dye molecule, to dye molecule affinity higher,
To improve dyefastness；Dacron prepared by the present invention, can quickly to the gaseous state moisture that is evaporated from skin surface into
Row moisture absorption, then via the moisture releasing of dacron surface, the unique physical hole of dacron interior surface prepared by the present invention with
And capillary effect caused by the gap between polyester fabric fibers is but also moisture is adsorbed in dacron, spreads and put
Wet, the result of two kinds of effects causes moisture that fast transferring occurs, and reaches moisture absorbing and sweat releasing effect.It is fine as aqueous water is also
After tieing up material absorption, to be released from material surface, this process is the drying of fabric, can preferably utilize capillary theory,
Dacron of the present invention is quickly absorbed water, water delivery, diffusion and volatilization, it can absorb rapidly skin surface moisture and sweat
Water, and it is discharged into outer layer evaporation.Dacron of the present invention is more preferable than traditional terylene cloth capability and performance.
