Therefore, the velvet fabric obtained by knitting the regenerated polyester filament DTY heavy net and the regenerated polyester and lycra has excellent fuzzing and pilling resistance.
Meanwhile, velvet fabric woven by the regenerated polyester filament DTY heavy net, the regenerated polyester and the lycra has good stretching and elastic recovery performance, and the three yarns are compact in structure and contain a large amount of static air to isolate external cold air. Therefore, the velvet fabric finally obtained is plump in fluff, fine in texture and high in elasticity, and has excellent fuzzing and pilling resistance and heat preservation performance.

Preferably, in the S3 post-finishing process, the mass percentage concentration of the softener aqueous solution is 0.5-2%.
By adopting the technical scheme, the reaction efficiency of the softening agent and the fibers in the grey cloth is improved, and the fibers are favorably separated from each other. Meanwhile, part of the softening agent which does not react with the fibers is deposited or adsorbed on the surfaces of the fibers to play a role in lubrication, so that certain friction coefficient exists among the fibers, the napping efficiency and effect of the grey cloth are improved, and the thermal insulation performance of the finally obtained fabric is improved.
Preferably, in the S3 post-finishing process, the softener aqueous solution is a cationic modified polysiloxane (Silicone) emulsion, and the pH value is 5.0+/-1.0.
By adopting the technical scheme, on one hand, the gray fabric is padded with the softener aqueous solution and reacts with the fibers in the gray fabric, so that the fibers are mutually separated, and the gray fabric is napped; on the other hand, the softener aqueous solution which does not react with the fibers is deposited on the surfaces of the fibers, so that the relative sliding among the fibers is reduced, and the napping treatment of the grey fabric is facilitated.
Therefore, after the regenerated polyester filament yarn DTY heavy net, the regenerated polyester and the lycra are treated by a specific weaving process and a post-finishing process, the degree of density of the surface terry of the obtained fabric is improved, the coverage rate of the terry surface is high, and the warmth retention property and the pilling resistance of the obtained fabric are effectively improved.
