A process for producing crimped polyester filament by winding the filament round heated roll and a device thereof. The process comprising :the polyester filaments are spun from spinning nozzle(1) to split into two or more filament bundles(3), said splitted filament bundles wind separately round an electrically heated rotary roll (2) one or two turns, the bundles which are heated by electrically heated roll are combined into a yarn and wound into a cake(4). The yarn then is made into woven fabric. The polyester filaments or woven fabric can produce natural crimp after that the woven fabric is treated with hot water. By comparing with the art, the present process has reasonable design, simple device, the produced polyester filament and the woven fabric have natural crimp etc.

The invention discloses a polyester filament yarn producing device. The polyester filament yarn producing device comprises a polyester filament yarn nozzle, polyester filament yarn, a grouping device used for dividing the polyester filament yarn into two groups and a yarn cake winding device. A heating device is arranged on one bunch of tows of the divided polyester filament yarn, and a thermal insulation device is arranged between the two groups of polyester filament yarn. As the physical property of the polyester filament yarn at one side is changed through hot air heating, the polyester filament yarn which is not treated and located at the other side and the treated polyester filament yarn are combined and wound into spinning yarn cakes for a spinning machine to use, and as the thermal insulation device is arranged between the two bunches of tows, it is avoided that the tows are heated at the same time to affect performance; compared with the prior art, the technological design is reasonable, production equipment is simple, cost is low, and the polyester filament yarn producing device has high popularization value.
