A process for treatment of polyester fabrics imparts improved characteristics to the fabric, including improved moisture wicking, soil-release, and soil-redeposition properties, and less static cling. The process comprises treatment of the fabric with a caustic solution, preferably in the presence of an appropriate catalyst, followed by the application of a polyester copolymer, the copolymer having both hydrophobic and hydrophilic groups. The process treats the entire fabric, not just the surface, and provides a product sufficiently comfortable to be used for intimate apparel and active sportswear.

Process for treatment of polyester fabrics

An improved process is provided for the transfer printing of textile materials. In the process of this invention a heat sublimable dyestuff is printed onto a carrier sheet. The carrier sheet is then brought in contact with the textile material to be printed. Sufficient heat and pressure is applied for a suitable dwell time causing sublimation of at least a substantial portion of the dyestuff from the carrier sheet. The volatilized dyestuff is then transferred and deposited on the surface of the textile material to be printed. The carrier sheet is then separated from the textile material. The printed surface of the textile material is then heated to at least the sublimation temperature of the dyestuff in substantial absence of a convective gas flow, other than the volatilized dyestuff and maintained at this temperature until a given desired degree of resublimation and deposition of the dyestuff from the surface of the textile material to the interior of the textile material is obtained.
