The process is called False Twist. DY ratio is calculated as follows.

Textile Science Draw Textured Yarn

The fashion and textile industry continues to leave behind a huge environmental footprint.

. B cooling the filaments and combining them to form a yarn. Fiber is curly fluffy and has a high elasticity. 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.

The difference from FDY is that it has a false twisting process. DTY maintains characters of synthetic filaments. But in a relaxed state it will shrink and become fluffy.

The properties of false-twist textured yarns in the aspects of crimp characteristic and tensile behavior depend mainly on the draw ratio and the DY. Shaft 1 is the input feeding device for the POY. DY Circumferential speed of disks mmin.

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. Prepared DTY stretch yarns have anti-static and antibacterial functions are good in stability and can meet different. 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.

The process is particularly useful for the manufacture of. In our plant we declared earlier the final product of POY is to go to the Draw Textured draw Tension Draw warping. A continuous spin-draw-false twist texturing process for producing a textured nylon yarn having high yarn uniformity the process comprising the steps of.

The other thing to know about draw textured yarn is that the color can be changed from one dye lot to another. Such as crimp bulkiness crease etc. Drawn Textured Yarn DTY yarn is made when Polyester POY is simultaneously twisted drawn.

Draw textured yarn DTY is made from Partially Oriented Yarn POY. After heating the raw material is drawn and twisteduntwisted simultaneously resulting a bulked stretchy yarn. The knitter then transfers the wool onto a cotton cloth using a needle.

When POY is fed into the machine the yarn has to be drawn. This is manufactured by texturising partially oriented yarn using texturising machines. The inter-ﬁber bonds break and reform during the texturing process.

The first step is to distort the ﬁlament in the. When the POY is drawn and Twisted at the same time the end product obtained is a draw textured yarn. From here the yarn is fed to Shaft 2.

DTY Draw Textured Yarn is the most used texturing process in synthetic fabrics. During the process of yarn texturizing a partially oriented yarn is used as feed yarn. Spinning speeds between 3000 mmin to 4000mmin provides a partially oriented yarn which later requires draw of two during the draw texturizing.

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. The technical specifications of draw textured yarn have made it ideal for a wide range of applications as it can be moulded in several ways as well. Draw Textured Yarn DTY market report discuss the manufacturing process examined systematically with respect three points viz.

A ﬁlament yarn is generally textured through three steps. Raw material and equipment suppliers various manufacturing. 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 properties of the textured yarn can be altered by changing these parameters. Feed yarn for said draw-texturing process has a a break elongation of 40 - 80 b a density of above 1371 gcm 3 and c a boil-off shrinkage. Setup in 2017 our division of Yarn for Technical textile Industrial end use offers high tenacity yarns which are used for a wide variety of applications.

Texturizing can be termed as the process in which loops crimps or coils are introduced into a continuous filament yarn. DTY is nylon drawn textured yarn it is manufactured with POY through draw-twisting. Thermoplastic ﬁlament yarns are used in most texturing processes.

DTY process is similar to perming hair. Draw ratio DY ratio and heater temperatures are the main process parameters to change 3t. The first heater length and temperature were 25 m and 190C respectively.

This process can be started by knitting together a series of stitches. POY which stands for Partially Oriented Yarn is now the standard feed yarn for the texturing process. DTY is suitable for fabric end uses like outerinner garments skin-clinging garments furnishings upholstery etc.

The ratio of the disk surface speed to the yarn speed is usually referred to as DY ratio. You can do this by adding more wool at the end of the yarn. Process speed was 650 mmin.

150 denier 96 filaments semi-dull PET partially oriented yarn POY was draw-textured on the lab-type Barmag AFK-M texturing machine with two heaters. Draw Texturised Yarn DTY is a fully drawn fully oriented polyester multifilament yarn with soft crimp high bulk and texture with cotton feel and very high durability and retention properties. Changes on production parameters of textured yarn properties.

After producing the POY yarn it is going for Texturing process to give many types of effect on the yarn. It is a continuous filament yarn spun at a speed which is for example for polyester around 3200 mmin. Yarns for Technical Textile.

Then subjected to simultaneously false twisting friction disc device heating. DTY is the abbreviation of draw texturing yarn and the Chinese name is. Draw Texturing Process is discussed below.

After the false twisting the DTY passes through the additional heating zone to become a set-DTY. Using high quality raw materials advanced processing technology quality is guaranteed. A melt spinning a plurality of nylon filaments from nylon polymer.

With growing environmental concerns and sustainability. Textured polyester yarn is prepared from multifilament yarn composed of a synthetic linear ethylene terephthalate polyester by draw-texturing at a draw ratio of 105 - 130X using a heat-setting temperature of about 170 - 240. Its yarn fabric has a soft skin-friendly soft color characteristics.

DTY yarns are known as thread Heat set and bulky filament. The so-called false twist is that the yarn is twisted in a certain direction during the subsequent processing and the yarn is still straight when wound. The invention relates to an anti-static and antibacterial nylon 6 DTY draw textured yarn stretch yarn process achieved on high-speed spinning equipment by taking nylon 6 slices and additives as raw materials and adopting a POY pre-oriented yarn-DTY process.
