ITY polyester thread (self-textured filament)

ITY polyester yarn (self-textured filament yarn) is one of the newest products of Syring Yazd Manufacturing Factories Group (the largest producers of polyester and polypropylene yarns in Iran).

ITY polyester yarn stands for INTERMINGLED TEXTURED YARN, which is also known as BSY or self-textured yarn, it is a group of filament yarns that are woven from them without using the texturing process and by applying heat and finishing treatment on the woven fabric. , they give a similar effect to textured yarns and today they have been able to take an important share of the yarn consumption market in the weaving industries of fabrics needed for clothing, especially women’s clothing.

The general principles of their production process is the merging of 2 filament yarns with different shrinkage characteristics (for example, two FDY and POY yarns) with each other. It gives the same texture to the final fabric.

Description

Brief history:

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 continuation of the research included the combination of two or more types of yarn with different characteristics (especially thermal shrinkage). Today, ITY yarns, which stand for Intermingled Textured Yarn or Interlock Twist Yarn or Interlace Textured Yarn, are produced from the combination of POY and FDY yarn with different shrinkage percentages. Also, the term (BSY) Bi-Shrinkage Yarn, which means a yarn that shrinks in itself, is also used for ITY yarn.

Method of production:

Two-step method:

In the two-step method, POY and FDY yarns are produced in separate processes and then merged together. The following methods are usually used to integrate these yarns in the two-stage production method:

Integration of yarns on the tension-swing machine
Merging of yarns on the stretching-twisting machine
Consolidation of threads on the single-wheel machine

Due to the increase in the use of ITY yarns in the textile industry, the mentioned methods are not cost-effective, so the single-step production method of ITY yarn is used.

One-step method:

With the development and optimization of spinning melting machines, it is possible to produce ITY yarn in one step. In this method, POY yarn and FDY yarn are produced and integrated in a spinning melting machine. This method increases the production speed of ITY yarn to more than 3200 meters per minute.

The following types of fabrics produced from self-textured filament yarn:

  1. The soft underhand of peachskin fabric (peach skin)
  2. Silk underwear (scroop cloth)
  3. Subordinate to Shantung
Attributes

Due to the structural features of POY yarn, its presence in the ITY structure improves the dyeability properties. Also, due to the different shrinkage percentage of POY and FDY, the resulting ITY yarn has curls and waves in its structure without the need for warping and thermal stabilization (texturing process). As a result, the resulting ITY yarn without texturizing has a textured state, hence it is known as self-texturing yarn.

    Dear Sirangcoop

    I am interested in ITY (Interlaced Textured Yarn) or BSY, as it is commonly known. It’s a fascinating product, given that it is produced through the intermingling of POY and FDY.

    I would appreciate your insights on the following:

    1)Could you provide details on the denier, filament count, ply, and other specifications of the ITY yarn your company offers?
    2)A rough price indication would be helpful for reference.
    3)As a trader in India, I would like to understand the market potential. Which types of fabric manufacturers typically use ITY yarn, and who could be my potential customers? This will help me identify and approach the right clients.
    Looking forward to your response.
