The properties of the textured yarn can be altered by changing these parameters. The ratio of the disk surface speed to the yarn speed is usually referred to as DY ratio.

The invention relates to a texturing machine for draw texturing a plurality of synthetic yarns comprising a corresponding plurality of processing stations.
. DY Circumferential speed of disks mmin. Draw texturing is defined as a process when an incompletely drawn feeder yarn is drawn to the intended yarn size and textured in a continuous manner. The process of introducing crimp loop coils to continuous filament yarn is called Texturizing.
DTY yarns are known as thread Heat set and bulky filament. What is DTY. Knit - deknit False twist process Yarn is twisted heat set and then untwisted by spindle - forms distorted helical coil The coil straightens out when stretched Draw texturing.
Here the yarn is first drawn with a draw ratio of the order of 23 to 35 at a temperature of at least 50 Tg 40oC. Patents-wipo DTY with a short process high efficiency good quality and features is a synthetic polyester textured yarn type which is based on polyester chips as raw material the use of high-speed spinning POY and. The texturizing process imparts bulk and stretch properties.
Further many heating techniques are used to make the yarns suitable for specific applications. Ways to texture filament yarns 5 1. 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.
It concludes with a brief review of the draw yarn manufacturing process. The process is particularly useful for the manufacture of. Drawn Textured Yarn DTY yarn is made when Polyester POY is simultaneously twisted drawn.
It is a mechanical method. The process flowchart of the draw texturing process has given below. Then subjected to simultaneously false twisting friction disc device heating.
DTY is nylon drawn textured yarn it is manufactured with POY through draw-twisting. False twist process 2. The draw textured yarn presents a different.
A process for producing a polyester textured yarn which comprises drawing and simultaneously false-twisting an undrawn polyester yarn using a draw texturing apparatus equipped with a heat-treating heater and a false twister between feed rollers and draw rollers wherein the undrawn polyester yarn has a birefringence Delta n of 001 to 005 and the draw ratio DR is adjusted. Two types of manmade POY can be textured- Nylon Used in manufacturing of ladies hosiery Polyester Used in apparel. For further information please refer to the references listed at the end of this article.
Draw ratio DY ratio and heater temperatures are the main process parameters to change 3t. It has a decisive effect on the fabric warmth and clothing comfort. These yarns are also called Air Textured Yarns ATY as the texturizing on the yarn is produced by using an air jet.
It also discusses the Physical properties of draw textured yarn and its variations in draw ratios. Creel pipe Cutter Cutter guide Rubber Cote apron Twist Stopper pulley Primary heater Cooling plate Spindle drawtwisting Intermediate Secondary heater Oiler roller. The yarn develops texture by a process involving hot drawing twisting thermosetting and de-twisting.
DTY refers to Drawn Textured Yarn. DY ratio is calculated as follows. Follow me see the production process.
Polyester DTY Yarn has endless varieties of applications in the apparel and non-apparel industry ranging from weaving knitting of fabrics for clothes to home furnishings and seat covers. It stabilizes the POY through heating and drawing. After the false twisting the DTY passes through the additional heating zone to become a set-DTY.
Draw Textured Yarn are produced by simultaneously twisted and drawing polyester partially oriented yarns POY using high speed texturizing machines. Fiber is curly fluffy and has a high elasticity. Draw texturized yarn is the most used texturing process in the textile industry owing to the numerous advantages associated with it including its ability to process continuous-Filament yarns of different types of polymer and not only thermoplastics.
The yarn develops a texture by twisting and drawing it at the same time using heat. This article covers Polypropylene Draw Texturing Machine and its uses. Different heating techniques can be used to make the yarn set for specific use.
Polyester Draw Textured Yarn PDTY is obtained when the Polyester Partially Oriented Yarn POY is simultaneously twisted and drawn. Basically the draw texturing process is currently on a plateau where a signifi cant advance in process technology is diffi cult to realise and profi t margins are squeezed to the extent that draw textured yarn manufacturing can largely survive only in lower labour cost regions. Its yarn fabric has a soft skin-friendly soft color characteristics.
A false twist textured yarn is a continuous filament yarn that has been processed to introduce crimps coils loops and other fine distortions along the yarns length.
