What is ISO 2061:2015 Textiles — Determination of twist in yarns — Direct counting method
ISO 2061:2015 was published by the International Organization for Standardization (ISO), it specifies a method for determining the twist of a single yarn by direct counting. The method is applicable to all types of yarns, including those made from natural and synthetic fibers.
The standard describes the equipment and procedure required to measure the twist of a yarn accurately. It involves mounting a known length of the yarn on a tension device and then twisting the yarn in the opposite direction until it kinks. The number of twists required to produce the kink is then counted, and the twist per unit length is calculated.
The direct counting method described in ISO 2061 is a widely used and reliable technique for determining the twist in yarns. It is an important quality control test for the textile industry. As twist affects the appearance, strength, and performance of yarns in various textile products.
Requirements of ISO 2061:2015
ISO 2061:2015 specifies the requirements for determining the twist of a single yarn by direct counting. The standard provides guidance on the following aspects:
Apparatus: The standard specifies the apparatus required for carrying out the direct counting method. Which includes a tension device, a twist tester, and a counting device.
Test specimens: The standard specifies the requirements for the test specimens, which should be representative of the yarn being tested. The length of the yarn to be tested is also specified in the standard.
Testing procedure: The standard provides detailed instructions on the testing procedure. Including the mounting of the yarn on the tension device, twisting the yarn in the opposite direction until it kinks. Also, counting the number of twists required to produce the kink.
Calculation: The standard specifies the calculation method for determining the twist per unit length of the yarn based on the measured twist angle and length of yarn.
Reporting: The standard provides guidelines on the reporting of the test results. Including the units used, any relevant conditions of the test, and any deviations from the standard testing procedure.
Therefore, It is an important standard for the textile industry, as it ensures that the twist of a single yarn is measured consistently and accurately. Which is crucial for maintaining the quality of textile products.
Benefits of this standard
The benefits of ISO 2061:2015 are as follows:
Quality control: The standard provides a reliable and accurate method for determining the twist of a single yarn. This is an essential quality control test for the textile industry. As the twist affects the appearance, strength, and performance of the yarn in various textile products.
Standardization: The standard ensures that the twist of a single yarn is measured consistently and accurately, regardless of the type of yarn or the manufacturer. This helps to standardize the testing process and ensures that the results are comparable between different laboratories.
Cost savings: The standard provides a cost-effective method for measuring the twist of a single yarn. As the required equipment is relatively simple and inexpensive compared to other methods.
Improved productivity: By providing clear guidelines for the testing procedure, the standard helps to improve the efficiency and productivity of testing laboratories. This ensures that the testing process is carried out quickly and accurately. Minimizing the risk of errors and delays.
Finally, Enhanced customer satisfaction: By ensuring that the yarns meet the required quality standards, the standard helps to enhance customer satisfaction with the finished textile products. This, in turn, helps to build customer loyalty and increase sales.
Who needs ISO 2061:2015?
ISO 2061 is relevant to the textile industry. Particularly to manufacturers, suppliers, and testing laboratories that produce, distribute, or test yarns made from natural or synthetic fibers. This standard is particularly important for those who produce or use high-quality textiles where yarn twist is a critical factor affecting the product’s appearance, durability, and performance.
The standard is also relevant to regulatory bodies, standards organizations, and accreditation bodies responsible for ensuring compliance with quality standards in the textile industry.
ISO 2061:2015 provides a reliable and accurate method for measuring the twist of a single yarn, and as such, it is an essential quality control test for the textile industry. Hence, Manufacturers, suppliers, and testing laboratories can use this standard to ensure that their products meet the required quality standards. Also, regulatory bodies can use it to enforce compliance with these standards.
