Draw Texturised Yarn (DTY) is manufactured by texturising partially oriented yarn using texturising machines. Polyester DTY yarn is a continuous filament yarn that has been processed to introduce durable crimps twists, interlaces, loops or other fine distortions along the lengths of the filament. Yarns made from thermoplastic materials can be textured by heat setting in a twisted condition,which results in polyester DTY yarn of greater bulk, higher stretch, and more pleasing aesthetics.
