Polyester/Nylon Drawing Texturing Process:
Fibres can be drawn either as an integral part of the spinning operation or in a separate step. Fibres such as nylon and polypropylene can be drawn without applying external heat (or at a temperature no greater than about 70 °C [160 °F])—a process referred to as cold drawing. Other fibres, such as polyester, that are spun at extremely high rates yield what is known as partially oriented yarns (POY)—i.e., filaments that are partially drawn and partially crystallized and that can be drawn at a later time during textile operations.

Drawing is a process where a group of slivers or filaments is elongated by passing them through a semi-series pair of rollers pairs. Each pair of roller moving faster than the previous one. After drawing, drawn filaments are wound with or without twist into a package. For many applications, flat filament yarns are textured to gain increased bulkiness, porosity, softness, and elasticity in some situations. Thermoplastic filament yarn is used in most texturing processes. The inter-fiber bonds break and reform during the texturing process.

Drawn Textured Yarn:

Polyester Drawn Textured Yarn commonly known as Polyester DTY is a manufactured by processing Polyester POY. This process disperses, curls and entangles the filaments composing the POY yarn, which gives DTY a fluffy appearance and gives it the properties of both natural and synthetic fiber.

Polyester Drawn Textured Yarn commonly known as Polyester DTY is a manufactured by processing Polyester POY. The yarn develops a texture by twisting and drawing it at the same time using heat. The yarn develops texture by a process involving hot drawing, twisting, thermosetting and de-twisting.  The texturizing process imparts bulk and stretch properties. Different heating techniques can be used to make the yarn set for specific use. This process disperses, curls and entangles the filaments composing the POY yarn, which gives DTY a fluffy appearance and gives it the properties of both natural and synthetic fiber. DTY can be provided with different levels of intermingling depending upon the requirements of downstream machines and applications. It can be Non-Intermingle (NIM), having 0 -10 knots/meter or Semi-Intermingle (SIM) having 40 - 50 knots/meter or High-Intermingle (HIM) having 100 - 120 knots/meter. These knots are created by usage of specific intermingling nozzle and subjecting yarnto desire intermingling pressure. DTY can be used in various applications, as a placement of natural yarns, or in specified technical applications.
