Draw ratio DY ratio and heater temperatures are the main process parameters to change 3t. From here the yarn is fed to Shaft 2.

Textured Yarns Tepar

Manufacturing of draw textured yarns was for nearly a decade characterized by manual processes.

. A ﬁlament yarn is generally textured through three steps. It has a decisive effect on the fabric warmth and clothing comfort. DTY is the abbreviation of draw texturing yarn and the Chinese name is.

DTY maintains characters of synthetic filaments. POY which stands for Partially Oriented Yarn is now the standard feed yarn for the texturing process. After heating the raw material is drawn and twisteduntwisted simultaneously resulting a bulked stretchy yarn.

An improved multifilament polyester feed yarn suitable for substantially eliminating broken filaments when producing false-twist textured yarn by combined draw-texturing processes werein heat-setting temperatures are above 200C said feed yarn being characterized by a break elongation of 70 to 180 percent by a birefringence value of at least 0025 by an interfilament. What is Fibre drawing. 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.

Draw ratio Yratio and heater D temperatures are the main process parameters to change 3t. Fiber is curly fluffy and has a high elasticity. The second step is to heat the yarn which breaks bonds between polymers allowing the ﬁlaments to stay crimped.

It is a continuous filament yarn spun at a speed which is for example for polyester around 3200 mmin. Texturizing can be termed as the process in which loops crimps or coils are introduced into a continuous filament yarn. The feed yarns need not be restricted to the synthetic filament yarns.

Its yarn fabric has a soft skin-friendly soft color characteristics. DTY process is similar to perming hair. The first step is to distort the ﬁlament in the yarn so that the inter-fiber bond is broken.

Twisting or other means are used to distort the ﬁlaments within a yarn. Then subjected to simultaneously false twisting friction disc device heating. DTY yarns are known as thread Heat set and bulky filament.

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. The ratio of the disk surface speed to the yarn speed is usually referred to as DY ratio. With changing manufacturing conditions in main production areas the process requirements have changed as well and automatic machines reappear in focus.

Textured yarn can be altered by changing these parameters 1. Drawn Textured Yarn DTY yarn is made when Polyester POY is simultaneously twisted drawn. DTY Draw Textured Yarn is the most used texturing process in synthetic fabrics.

This is manufactured by texturising partially oriented yarn using texturising machines. DY ratio is calculated as follows. Drawn Textured Yarn DTY yarn is obtained when Polyester POY is simultaneously twisted drawn.

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. It can cover the spandex yarn and make into covered yarn and the. DY min min throughput speed of yarn m circumfere.

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. Draw Texturised Yarn 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. Shaft 1 is the input feeding device for the POY.

Spinning speeds between 3000 mmin to 4000mmin provides a partially oriented yarn which later requires draw of two during the draw texturizing. After the false twisting the DTY passes through the additional heating zone to become a set-DTY. The present invention relates to a method for producing an interlaced exothermic polyester composite twisted yarn after twisting a basalt-containing polyethylene terephthalate filament as an.

After producing the POY yarn it is going for Texturing process to give many types of effect on the yarn. In our plant we declared earlier the final product of POY is to go to the Draw Textured draw Tension Draw warping. Such as crimp bulkiness crease etc.

When POY is fed into the machine the yarn has to be drawn. The process is particularly useful for the manufacture of. DTY is nylon drawn textured yarn it is manufactured with POY through draw-twisting.

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 properties of the textured yarn can be altered by changing these parameters. 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 δn of 001 to 005 and the.

DTY yarn is mainly used in weaving knitting of fabrics for making clothes home furnishings seat covers bags and many other uses. Such twisted yarn can also be heat-set to make the yarn permanently thermo-set the twist. The difference from FDY is that it has a false twisting process.

Process Of Producing Polyester Draw Textured Yarn Containing Basalt Having Excellent Exothermic Property. 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. Air Textured Yarn ATY Air texturing process is a purely mechanical method that uses a cold air-stream to produce bulked yarns with cotton touch and warmth.

The process is called False Twist. The eAFK draw texturing machine is Oerlikon Barmags next. DY Circumferential speed of disks mmin.

The ratio of the disk surface speed to the yarn speed is usually referred to as Yratio. 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 air textured yarns closely resemble spun yarns in their appearance and physical characteristics.

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. DYratio is D calculated as follows. Draw Texturing Process is discussed below.

During the process of yarn texturizing a partially oriented yarn is used as feed yarn.
