The invention belongs to the technical field of 
textile fabrics, in particular to a full-
polyester cotton-like fabric and a preparation method thereof. The full-
polyester cotton-like fabric comprisesa first weaving layer, a second weaving layer and a third weaving layer, wherein the 
layers are laminated and arranged so that the 
fabric structure is compact and the 
wear resistance is good; each layer is made of a composite 
fiber attached with different additives to improve the performance of the fabric. In the first weaving layer, a 
hydrogen bond is formed on the surface of nano organic 
montmorillonite and the surface of a first 
polyester fiber core, and the bonding is firm and pilling is avoided; 
silicon carbide, 
triphenyl phosphite are matched with the nano organic 
montmorillonite, so that the anti-melting property, 
softening feeling and sagging feeling of the fabric are improved, and the fabric has the affinity of cotton and good 
wrinkle resistance; aluminum 
oxide coated 
barium titanate and 
nano zinc oxide are matched with the nano organic 
montmorillonite, so that the antistatic performance is improved. The preparation method of the full-polyester cotton-like fabric has the advantages that color master batch is used for preparing the 
fiber core, the color fastness is high, and the 
dyeing arrangement is not needed. The method is economical and environment-friendly.
