Different fibers and threads are used to produce different fabrics in the textile industry. One of the most widely used fibers and threads is polyester thread. This yarn is used in two different ways, i.e. pure use or combined use with two or more other fibers to produce and prepare fabric or other textiles.

Types of polyester yarn

Polyester yarns are classified according to their function and application. According to this issue, in general, this thread can be divided into 6 different categories, which we will examine in the following.

DTY threads: DYT thread, which is known as single-threaded thread. And in Iran, it is also called as terroira thread, it is a type of polyester thread. DTY yarns are widely used yarns and have many and varied applications, especially in the textile industry. These threads have different properties such as softness and high softness and volume. DTY yarns are produced through several steps and under factors such as very high heat.

ATY yarns: ATY yarns are another type of polyester yarns, which are also known as air-textured yarns. This eventually causes the yarn to tangle, making it look like natural yarn. Air Tekshere yarns also have many and different uses in the preparation of various textiles such as blanket yarn and weft, rug and carpet weft. One of the most important features of these polyester threads is their low moisture absorption and light weight.

POY threads: One of the types of polyester thread that has special and important features, this is POY thread. This thread is created by melting polyester chips. One of the important features of this yarn is its remarkable thermal properties, high flexibility, and its suitable hanging properties.

FDY yarns: These polyester yarns are the result of the contraction of POY yarns. This shrinkage makes these threads to be used in various industries such as the textile industry and various textile products such as curtains, rugs, blankets, carpets...

Staple yarns: Another type of polyester yarn is staple yarns. These threads are cut filament fibers that are produced in a rotary system. These fibers are finally packed and delivered to the textile factory in the form of bales.

Intermingle yarns: Intermingle yarns are in the category of this model and are produced from DTY yarns. These threads are welded at specified intervals in DTY threads. These threads have important features such as softness and volume. By passing through the texturing stage, these threads become similar to threads made from natural fibers. This makes the resulting fiber very strong and durable and is used in the production of various textiles such as clothes, clothes, rugs, etc.
