The twist amount and direction test of the yarn taken from the fabric is one of the most basic parameters in the quality control of woven fabrics. This test, performed according to TS 256 and TS ISO 7211-4 standards, evaluates the performance and durability of the fabric by determining the twist properties of the yarn in the production process. For manufacturers, importers and retailers, this test is critical for both compliance with international standards and meeting customer expectations.
What is the Test for the Twist Amount and Direction of the Yarn Taken from the Fabric?
This test performs quality assessment by measuring the number of twists and the twist direction of the yarns removed from the fabric on one ply. The TS 256 and TS ISO 7211-4 standards define the methods used to determine the degree of twist of the yarn in the S or Z direction. This information directly affects the end-use performance of the fabric and is indispensable for quality controls in the production process.
For Which Products?
Suitable for woven fabrics made of different fiber types such as cotton, polyester, viscose and wool. It is especially preferred in technical and fashion textiles that require high durability and homogeneous quality.
Importance of TS 256 and TS ISO 7211-4 Standard
These standards enable yarn twist properties to be evaluated by internationally recognized methods. It is the basic reference for the preparation of technical reports required in CE approved certification processes and export procedures.
Commercial and Legal Advantages
Twist quantity and direction test results contribute to brands gaining trust in the market with quality certificates. For large retailers and supply chains, it is an important indicator in the acceptability process.
