ITY

ITY Yarn is one of the polyester filament yarns produced by combining POY and FDY with different shrinkage percentages. The difference in the behavior of these two components creates a crimped and wavy structure in the yarn, which is why ITY is also referred to as self-textured yarn in Zigma’s technical documents. The presence of POY in the yarn structure also helps improve the dyeability properties of the final product.

For industrial customers, purchasing ITY yarn should be based on yarn count, filament number, Grade, application, color condition, number of cones and order weight. In Zigma’s available product list, ITY counts of 80 and 135 and filament numbers of 72 and 108 are registered, with its main listed application being twisting.

Introduction and Applications of ITY Yarn

ITY yarn consists of two components, POY and FDY. According to the product technical specification, the difference in shrinkage percentage between these two components causes the yarn to develop a crimped and wavy structure without requiring a separate texturizing process. Therefore, ITY can be a suitable option for products requiring a structure different from completely smooth yarns.

Another important feature of polyester ITY yarn is the presence of POY in its structure, which according to technical information helps improve the dyeability properties of the final product. This factor is important for manufacturers who require control over the appearance and uniformity of the final product.

ITY can be used both without twist and after twisting operations in the production of apparel fabrics. According to Zigma’s available product information, the use of ITY in twisting is registered as its main application.

Therefore, when purchasing ITY yarn in bulk, customers should specify whether the yarn will be used directly or will enter the twisting stage, as the application affects product specification selection.

Technical Specifications and Available ITY Yarn Counts

One of the most important criteria for selecting ITY in B2B transactions is yarn count and filament number. In the current available product list, combinations related to counts 80 and 135 and filaments 72 and 108 are registered. Two samples specifically available in the technical product specifications are ITY 80/72 and ITY 135/108.

For example, the technical specification of ITY 80/72 records strength above 2 g/den, elongation of 40 to 55 percent, circular cross-section, maximum bobbin diameter of 39 cm and maximum bobbin weight of 10 kg. The packaging of this product is also listed as pallet packaging in the range of 600 to 750 kg.

For ITY 135/108, strength above 2 g/den, elongation of 40 to 55 percent, maximum bobbin diameter of 39 cm and maximum bobbin weight of 10 kg are also recorded.

The technical specification mentions the production capability of semi-matte white ITY yarn in the range of 80 to 225 denier. This range represents technical production capability, and for information about available counts at the time of ordering, current stock should be checked.

Regarding luster, there are two levels of information: the ITY technical specification introduces the product as semi-matte white, while the available product approval form identifies current yarns as matte. Therefore, the exact luster type and availability of each count should be confirmed during inquiry.

Quality Grade and ITY Yarn Selection Conditions

Along with technical specifications, ITY yarn Grade is one of the important details for industrial orders. According to Zigma’s approved information, the weight grading of ITY is defined similarly to FDY.

Grade A has a weight of approximately 9 kg per cone and is free from quantitative and qualitative defects. Grade A- is in the approximate range of 5 to 9 kg and is supplied without quality defects but with lower weight. Grade AW is also registered with lower weight, in the range of approximately 300 g to 5 kg.

Another important factor for industrial customers is the yarn color condition. According to technical information, color condition means that after weaving and dyeing, the final product should be free from color shade variation and two-tone effects.

The issue of same batch weaving is also important in some productions, and according to recorded information, in some fabrics the consumed yarn should be from the same batch.

Regarding the exact ratio of POY and FDY in ITY structure, the technical form still records it as a subject requiring confirmation; therefore, the composition ratio should not be published generally on the product page unless it has been technically approved for a specific SKU.

ITY Yarn Packaging and Ordering Conditions

ITY yarn is supplied as bobbin and pallet. According to Zigma’s product approval form, ITY and FDY packaging is in 72-piece pallets, with an approximate pallet weight of 600 to 700 kg. Minimum order conditions are also announced as negotiable with customers.

In the technical specifications of ITY 80/72 and ITY 135/108, the maximum bobbin weight is 10 kg and pallet packaging range of 600 to 750 kg is listed. Therefore, the final pallet weight may vary depending on count, Grade and product conditions.

For B2B customers, in addition to order weight, number of cones is also important. According to technical information, number of cones and color condition are important ordering factors for all yarn products, because an unsuitable number of cones for the next-stage machine may cause waste or leave part of the yarn unused.

Therefore, when inquiring about ITY yarn, it is recommended to provide the required weight, number of cones and the next consumption stage.

Guide to Selecting the Right ITY Yarn

To select the right ITY yarn, the application should first be determined. If ITY is purchased as a raw material for twisting, yarn specifications should match the twisting process requirements. If the product is used without twist in fabric production, yarn count and filament number should be selected according to weaving requirements.

Before placing an order, the following information should be specified:

Yarn count and filament number, application, Grade, color condition, number of cones and order weight.

For example, a request for ITY 80/72 or ITY 135/108 provides more accurate information to the sales department compared with a general request for “ITY yarn” and enables faster checking of stock and product specifications.

In comparison of ITY and FDY, ITY is made from a combination of POY and FDY with different shrinkage rates and naturally has a crimped and wavy structure, while FDY is a more fully oriented and smoother yarn. On the other hand, ITY is not the same as DTY, because the self-textured structure of ITY is created through the combination of its components, while DTY is produced through the texturizing process of POY.

ITY Yarn Price and Availability Inquiry

The price of ITY yarn may vary based on count, filament number, Grade, number of cones, order weight and current availability. Therefore, for industrial orders, price inquiries should be based on the customer’s exact requirements.

For receiving a suitable offer when purchasing polyester ITY yarn, the following information should be provided:

• Yarn count and filament number
• Required Grade
• Color condition if required
• Number of cones or order weight
• Application, such as twisting or weaving

Providing these specifications enables faster evaluation of ITY yarn availability, technical specifications and bulk sales conditions.
