Full title and description

Textiles — Universal system for designating linear density (Tex System). This international standard defines the principles, recommended units and conventions of the Tex system for expressing linear density of textile fibres, intermediate products and yarns, and provides conversion tables and guidance for implementation in trade and industry.

Abstract

ISO 1144:2016 gives the principles and recommended units of the Tex System for the expression of linear density and includes conversion tables for calculating tex values from other numbering/count systems together with guidance for implementation in trade and industry. The Tex System is applicable to fibres, tops, slivers, rovings, yarns and similar linear textile structures.

Scope

This standard specifies the Tex System as a universal method for designating linear density (mass per unit length) of textile yarns and related linear products, and provides conversion factors and tables to translate counts from other numbering systems into tex. It is intended for use across fibres, intermediate products (for example tops, slivers and rovings), yarns and similar linear structures for trade, testing and specification.

Key topics and requirements

• Definition and rationale for the Tex system (mass in grams per 1 000 metres).
• Recommended units and notation for expressing linear density in tex.
• Conversion tables and formulae to convert counts from other systems (for example indirect systems) into tex.
• Principles and conventions for commercial implementation and labelling in trade and industry.
• Applicability to fibres, intermediate products and yarns—consistent treatment across product types.

These are the principal technical elements users must apply when specifying or converting linear-density values in textile contexts.

Typical use and users

Manufacturers and converters of fibres and yarns, textile testing and quality laboratories, procurement and specification teams, standards committees, and trade bodies use ISO 1144:2016 to ensure consistent expression, communication and conversion of linear-density values (tex) across suppliers, buyers and testing organizations.

Related standards

ISO 1144:2016 replaces earlier editions and recommendations (for example ISO 1144:1973 and antecedent ISO/R recommendations). It is associated with other ISO and national standards that address yarn numbering, tests and terminology in textile metrology and trade.

FAQ

Q: What is this standard?

A: ISO 1144:2016 is the international standard that defines the Tex system for designating linear density (mass per unit length) of textile fibres, intermediate products and yarns.

Q: What does it cover?

A: It covers the principles, recommended units and notation of the Tex system, conversion tables and procedures for converting counts from other systems into tex, and guidance for implementation in trade and industry.

Q: Who typically uses it?

A: Textile manufacturers, quality and testing laboratories, procurement/specification teams, standards developers and trade organizations—anyone who needs consistent expression or conversion of linear-density values.

Q: Is it current or superseded?

A: ISO 1144:2016 is the current edition (Edition 2, published September 2016) and supersedes ISO 1144:1973 and prior recommendations; the ISO entry shows the standard as published and kept current by periodic review.

Q: Is it part of a series?

A: It is a standalone international standard focused on linear-density designation (Tex) but is commonly used alongside other textile metrology and yarn-testing standards developed by ISO/TC 38 and national bodies.

Q: What are the key keywords?

A: Tex; linear density; yarn count; yarn numbering; conversion tables; textile fibres; sliver; roving; textile metrology; ISO 1144.
