A Complete Guide to ISO 2060: Authoritative Standards for Determining Linear Density of Textile Package Yarns

In the field of textile production and trade, yarn linear density (mass per unit length) is one of the core indicators for measuring product quality and determining processing parameters. To ensure the accuracy, 일관성, and impartiality of yarn linear density test results, the International Organization for Standardization (ISO) has formulated the ISO 2060 기준, providing a unified testing method specification for the global textile industry. This article will comprehensively analyze the core knowledge of ISO 2060 from the aspects of basic standard information, core content, scope of application, and practical value.

나. Basic Standards: Positioning and Development History of ISO 2060

ISO 2060, officially titled “Textiles — Yarn from packages — Determination of linear density (mass per unit length) by the skein method”, is an international standard developed by ISO/TC 38 (Textiles Technical Committee) under SC 5 (Yarn Testing Subcommittee). First released in 1972, the standard was revised and issued as the second edition (ISO 2060:1994) ~에 1994. It was reaffirmed as valid through a review in 2025 and remains the core basis for yarn linear density testing in the global textile industry to this day.
As a method standard, the core objective of ISO 2060 is to standardize the testing process of linear density of package yarns, resolve inconsistencies in test results caused by differences in testing methods among different testing institutions and enterprises, and provide reliable technical support for textile raw material inspection, product quality control, trade settlement, and other links. Its formulation follows the general process of ISO international standards and requires approval by at least 75% of voting member states through global voting, ensuring the authority and international universality of the standard.

II. Core Content: A Complete Standard System for Skein Method Determination

The core content of ISO 2060:1994 revolves around the “skein method”, establishing a full-process specification from sample preparation to result calculation. It covers key links such as terminology definitions, testing principles, equipment requirements, environmental conditions, operating procedures, result processing, and report preparation. The following contents are particularly important:
1. Core Terminology and Definitions
The standard defines key terms such as linear density, commercial moisture regain, and commercial allowance, laying a foundation for a unified understanding of the testing process. 그 중, “linear density” is defined as the mass of yarn per unit length, usually expressed in tex (1 tex = 1 g/km) or its multiples and submultiples. This expression is consistent with relevant standards such as ISO 1139 ISO 1144, ensuring the coherence of the terminology system.
2. Testing Principles and Core Processes
The core principle of the standard is to calculate the mass per unit length by preparing skeins of yarn with a specific length, conditioning them, and then weighing them. According to whether the yarn has undergone scouring treatment, the standard specifies two core testing paths: one is the direct determination process for unscoured yarns, and the other is the determination process for scoured yarns (after removing finishing agents). 그 동안에, the standard provides seven optional procedures, with differences lying in sample conditioning and preparation methods. Since different procedures may lead to variations in test results, the standard clearly requires that the adopted procedure must be agreed upon by relevant parties (such as suppliers and buyers, testing institutions and entrusting parties).
The complete testing process includes: sample collection, pre-conditioning and conditioning (to ensure the yarn is under standard atmospheric conditions), preparation of test skeins (determining the length and quantity of skeins), weighing, calculation of linear density, and variability analysis of test results. The standard puts forward clear requirements for conditioning environment (온도와 습도), skein length accuracy, weighing equipment precision, 등. 예를 들어, conditioning must comply with the standard atmospheric specifications for textile testing, and the accuracy of skein length must be verified by special measuring tools (Annex A specifically specifies the method for verifying skein length).
3. Key Technical Requirements
To ensure the reliability of test results, ISO 2060 strictly limits the key parameters in the testing process:
•Sample Scope: Clarifies the sampling method and requirements for the number of packages of laboratory samples (detailed in Annex B) to ensure the representativeness of samples;
•Equipment: Specifies the technical indicators of core instruments such as skein winding machines, weighing balances, and conditioning equipment. 예를 들어, the precision of the balance must meet the testing accuracy requirements;
•Testing Boundaries: Defines the applicable and non-applicable scenarios of the method. For instance, it is applicable to single yarns (spun yarns, monofilaments, multifilaments), plied yarns, and cables, but not applicable to yarns with an elongation rate exceeding 0.5% under specific tension or yarns with a linear density exceeding 2000 tex (special testing conditions need to be negotiated for such yarns);
•Result Processing: Clarifies the unit and method for calculating linear density, and requires variability analysis of test results to ensure data stability;
•Annex Support: The standard includes 5 annexes, among which Annex A (Method for verifying skein length) and Annex B (Sampling procedure) are normative annexes and part of the standard; Annex C (Method for scouring yarns), Annex D (Rapid conditioning method), and Annex E (Linear density conversion factors) are informative annexes providing references for testing practice.

III. 응용 프로그램의 범위: Clear Application Scope and Limitations

The scope of application of ISO 2060 covers most package yarns, but there are clear boundary limitations, which must be focused on when using the standard:
Applicable Scenarios: Suitable for the determination of linear density of various package yarns, including single yarns, plied yarns, and cables commonly used in textile production. It can be widely applied in enterprise quality control, third-party testing, trade inspection, and other links. When the determination of linear density needs to be combined with yarn strength testing or commercial quality inspection, the standard allows negotiating adjustments to the skein length, which must be clearly stated in the test report.
Non-Applicable Scenarios: In addition to the aforementioned “yarns with an elongation rate exceeding 0.5% under specific tension” 그리고 “yarns with a linear density exceeding 2000 tex”, the standard also explicitly excludes yarn types that have separate international standards (such yarns must comply with exclusive standards). 게다가, if it is necessary to determine the commercial quality of yarns (calculated in combination with commercial moisture regain), additional compliance with relevant commercial or legally agreed moisture regain standards is required.

IV. Practical Value: Standardized Support for the Textile Industry

As a globally unified standard for determining yarn linear density, ISO 2060 plays an irreplaceable role in textile production, trade, quality supervision, and other links:
•Ensuring Quality Consistency: Provides enterprises with a unified basis for quality control. By standardizing testing methods, it reduces deviations in product quality judgment caused by testing differences and helps improve production stability;
•Standardizing Trade Order: In international trade, unified testing standards avoid trade barriers caused by different methods in various countries, provide a fair quality judgment benchmark for both supply and demand parties, and reduce trade disputes;
•Supporting Industrial Chain Collaboration: From yarn manufacturers to fabric producers and clothing brands, the unified specifications of ISO 2060 ensure the consistency of understanding of yarn density indicators and test results across all links of the industrial chain, improving the efficiency of industrial chain collaboration;
•Promoting Technical Exchange: As an internationally accepted standard, ISO 2060 provides a common language for technical exchange in the global textile industry, helping enterprises learn from advanced international experience and improve technical levels.

V. Common Misunderstanding: Distinguishing ISO 2060 from PAS 2060

It should be particularly noted that some readers may confuse ISO 2060 with PAS 2060, but the two belong to completely different standard systems: ISO 2060 focuses on the determination of linear density of textile yarns, while PAS 2060 is a carbon neutrality verification standard issued by the British Standards Institution (BSI), which is mainly used to regulate the verification of carbon neutrality claims of organizations, products, and services. The two have no connection in terms of application fields and core objectives. 게다가, PAS 2060 has been replaced by ISO 14068-1:2023 since January 1, 2025, while ISO 2060:1994 remains valid after review in 2025. This difference also needs to be clearly distinguished to avoid misuse due to similar standard names.

VI. Conclusion

As an authoritative international standard for determining the linear density of yarns in the textile industry, ISO 2060:1994 provides reliable technical basis for global textile enterprises and testing institutions by establishing a unified and standardized testing process, and is an important support for ensuring yarn quality and standardizing trade order. Understanding and correctly applying this standard can not only improve the quality control level of enterprises but also help them better participate in international competition. In practical application, it is necessary to strictly follow the scope of application and technical requirements of the standard, 그리고 동시에, distinguish it from standards with similar names to ensure the accuracy and compliance of test results.
