Twisted or TFO yarn:In this article, we will examine twisted filament Twisted or TFO yarn  The twisting process in polyester filament yarns increases the cohesion of the filaments. Twist refers to twisting the yarn around its axis, and its increase, within the optimal range, increases the strength and improves the yarn underhand. Method of…

  In this article, we will examine Lycra or Spandex yarn. Lycra is a synthetic fiber that was produced by DuPont in 1958. Lycra is also known as Stomer or Spandex. In its research, the company was looking for ways to produce fibers that have the elastic properties of rubber but at the same time…

  Unique color effects can be seen in melange yarn due to the combination of two or more different colors. These color effects change with the wavy pattern in the yarn. Types of melange yarns: 100% cotton melange Cotton-polyester melange (with different percentages) Viscose-polyester melange (with different percentages) 100% polyester melange This type of yarn…

Brief history: To introduce the ITY yarn, we will first discuss the idea of ​​its formation. For the first time in 1960, in Japan, two types of yarn with different properties were combined with each other with the aim of creating a different yarn, and this yarn was called Shingosen (meaning new synthetic yarn). The…

Fully Drawn Yarn (FDY) is produced directly from the melting of polyester spinning chips. Its production process is similar to the production method of POY With the difference that by applying more tension during production, it reaches a perfect makeup. This yarn is also called FOY which means Fully Oriented Yarn. According to the production…

For the production of DTY yarn, the semi-arranged yarn (POY) in the texturizing operation is subjected to tension and heat to achieve more arrangement, and curls and waves are created in it, causing the yarn to become bulky and fluffy. POY yarn does not have the necessary strength and conditions for use in weaving and…

partially oriented  yarn (POY) is produced by melting polyester granule chips. In the melt spinning process, the polyester granule is melted at high temperature and then converted into filament. Finally, the filaments are put together and form the POY yarn. POY yarns are produced with different filament cross-sections, including circular, triangular, multi-ply and square or…
