ISO 11224:2003

Overview

ISO 11224:2003 - Textiles - Web formation and bonding in nonwovens - Vocabulary is an international vocabulary standard that defines terms used in the processing of nonwovens and the names applied to the resulting products. Published by ISO (Technical Committee ISO/TC 38, Textiles) as a second edition in 2003, it replaces the 1993 edition. The document is bilingual (English/French) and is intended to harmonize terminology across manufacturing, testing, procurement and research in the nonwovens sector.

Key topics

This vocabulary standard systematically defines terms for:

• Web formation processes - includes clear definitions for methods such as:
  • airlaying / airlaid
  • carding / carded
  • cross laying / cross-laid
  • drylaying / drylaid
  • electrostatic laying / electrostatically laid
  • flashspinning / flashspun
  • meltblowing / meltblown
  • parallel laying / parallel laid
  • random laying / random laid
  • spinlaying / spunlaid
  • wetlaying / wetlaid
• Terms for resulting products - standardized names for webs and nonwovens produced by each forming method (e.g., “airlaid web”, “meltblown nonwoven”).
• Web bonding processes - general definitions for bonding approaches used to convert a fibrous web into a nonwoven, including chemical (adhesive/solvent) and physical (entanglement, thermal) bonding, and distinctions such as area bonding vs. point/print bonding.
• Notes on usage - clarifications such as the varied use of the term “web” (single or multilayer) and equivalents in French.

Practical applications

ISO 11224 provides a common language for:

• Manufacturers and process engineers defining product specifications and production routes for nonwovens
• Quality, test and inspection teams ensuring consistent interpretation of sample descriptions and reports
• Procurement and R&D teams writing tenders, technical datasheets and research papers
• Educators and trainers teaching nonwovens technology (the standard permits reproduction of terms/definitions for strictly educational or implementation purposes under stated conditions)

Using standardized terminology reduces ambiguity in product claims, technical contracts and international collaboration across the nonwovens value chain.
