NOVELTY - The production process of polyester-nylon double-layer cotton flannel comprise: taking superfine denier FDY (fully drawn yarn) nylon yarns as warp yarns, taking superfine denier DTY (drawn texturized yarn) polyester yarns as weft yarns; warping the warp yarns and the weft yarns respectively in a split warping mode; sizing the warped warps and wefts, where the adopted sizing agent comprises 10-20 pts. wt. emulsified corn starch, 1-5 pts. wt. a penetrating agent, 1-3 pts. wt. a co-surfactant, 1-2 pts. wt. a softening agent, 0.5-1 pt. wt. graphene oxide gel and 70-80 pts. wt. water; carrying out shaft combination on the sized warp and weft, and weaving on a loom after drafting to obtain grey cloth; desizing, drying, sizing, dyeing, soaping, washing and drying the blank cloth. The co-surfactant is n-butanol or isobutanol. The penetrating agent is fatty alcohol-polyoxyethylene ether. The softening agent is an organosilicon softening agent. USE - Production process of polyester-nylon double-layer cotton flannel. ADVANTAGE - By adding emulsified corn starch, penetrating agent and co-surfactant to the slurry, under the combined action of the three, the permeability of the slurry on the fiber is improved, thus improving the production efficiency of polyester and nylon double-layer cotton flannel.
