Patent ID: 8617662

Claim:
A method of producing textile blind slat, comprising steps of: (a) weaving an elongated textile strip, wherein two longitudinal edge portions are double layered, for respectively forming elongated inner chambers therein; (b) immerging the elongated textile strip into a hardening agent, wherein the elongated textile strip passes through the hardening agent at a predetermined speed; the hardening agent comprises rigid polyacrylate latex, thermoplastic polyurethane emulsion, and flame retardant agent; (c) drying the elongated textile strip after being immerged in the hardening agent at a temperature between 100-180 Celsius degree; and (d) flattening the elongated textile strip by a flattening roller squeezing the textile after being dried at the temperature, so as to serve as a blind slat, wherein the flattening roller has a concave part, a convex part and a flat part provided between the concave part and the convex part, wherein a solid content of the polyacrylate latex is 3-4 times larger than a solid content of the thermoplastic polyurethane emulsion.
