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 inter-fiber bonds break and reform during the texturing process.

. 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 invention is further illustrated by the following Examples in which equipment as illustrated in the drawing was used with a Barmag texturising unit having ceramic discs. The knitter then transfers the wool onto a cotton cloth using a needle.
DY Circumferential speed of disks mmin. Process Of Producing Polyester Draw Textured Yarn Containing Basalt Having Excellent Exothermic Property. 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.
It is a mechanical method. DTY yarns are known as thread Heat set and bulky filament. This includes chemicals mentioned as reported.
The process is called False Twist. These yarns are also called Air Textured Yarns ATY as the texturizing on the yarn is produced by using an air jet. Draw-texturing process and textured polyethylene terephthalate yarns.
The properties of the textured yarn can be altered by changing these parameters. This yarn is intended to be used in place of cotton and cotton blend yarns that have a very low moisture content. The other thing to know about draw textured yarn is that the color can be changed from one dye lot to another.
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. 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. After producing the POY yarn it is going for Texturing process to give many types of effect on the yarn.
DY ratio is calculated as follows. Drawn Textured Yarn is produced by processing POY through a texturing process. What is DTY.
DTY Draw Textured Yarn is the most used texturing process in synthetic fabrics. JIANGSU WENFENG CHEMICAL FIBER GROUP CO LTD. 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 maintains characters of synthetic filaments. Follow me see the production process. FRANKFORT HANS R E.
Nylon microfine draw textured yarn producing device and process. Thermoplastic filament yarns are used in most texturing processes. In our plant we declared earlier the final product of POY is to go to the Draw Textured draw Tension Draw warping.
But in a relaxed state it will shrink and become fluffy. Draw Textured Yarn are produced by simultaneously twisted and drawing polyester partially oriented yarns POY using high speed texturizing machines. 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.
After heating the raw material is drawn and twisteduntwisted simultaneously resulting a bulked stretchy yarn. DTY is the abbreviation of draw texturing yarn and the Chinese name is. Textured yarn can be altered by changing these.
The texturing of a yarn gives a yarn characteristics that will enable the yarn to be. This web page summarizes information in PubChem about patent CA-1122369-A. This includes chemicals.
Draw Texturing Process is discussed below. After passing through the draw rolls 9 the textured yarn is interlaced by an air jet interlacer 12 and collected as a side-wound package 13. The process of texturing yarns for the textile industry involves the transition of partially oriented yarn POY through a texturing machine where the POY is exposed to heat air and tension to draw stretch or elongate the yarn.
You can do this by adding more wool at the end of the yarn. The ratio of the disk surface speed to the yarn speed is usually referred to as DY ratio. This process can be started by knitting together a series of stitches.
A filament yarn is generally textured through three steps. Polyester Draw Textured Yarn PDTY is obtained when the Polyester Partially Oriented Yarn POY is simultaneously twisted and drawn. DTY yarns are known as thread Heat set and bulky filament.
The first step is to distort the filament in the. Such as crimp bulkiness crease etc. The difference from FDY is that it has a false twisting process.
DTY process is similar to perming hair. A textured yarn is commonly referred to as a Drawn Textured Yarn DTY. Draw ratio DY ratio and heater temperatures are the main process parameters to change 3t.
Drawn Textured Yarn DTY yarn is made when Polyester POY is simultaneously twisted drawn.
