Overview
ISO 6173:1982 - "Open-end spinning machines - Vocabulary" is an ISO vocabulary standard that defines terminology specific to open-end (rotor-type) yarn production technology. Published by ISO/TC 72 (Textile machinery), the first edition (1982) limits its scope to machine parts and concepts unique to open-end spinning and excludes terms defined in other ISO standards (for example ISO 477 and ISO 2205). The standard is published in ISO’s three official languages (English, French, Russian) and includes German and Italian equivalents in annexes at the request of committee members.
Key topics and scope
This vocabulary standard focuses on clear, consistent definitions rather than performance requirements. Key topics covered include:
- Fundamental concept: definition of an open-end spinning machine - converting staple fibre into spun yarn by a continuous process where fibres assemble at the open end and twist is inserted independently of winding.
- Rotor-type machines: terminology for machines where assembly and twist insertion occur in the rotor.
- Opening and feeding devices: terms for the opening device, opening roller, feed unit, fibre channel, and trash removal system.
- Rotor components: definitions for slide surface, collection surface, separator, navel, doffing tube, and delivery rollers.
- Language and cross-reference notes: clarifies which terms are considered ISO terms (official languages) and points to related standards (ISO 477, ISO 2205) for components defined elsewhere.
Practical applications and users
ISO 6173 is primarily a reference for ensuring consistent terminology across documentation, design and communication in the textile industry. Typical users and uses:
- Machine manufacturers - to standardize component names in drawings, manuals and parts lists.
- Textile engineers and process designers - to reduce ambiguity in specifications and technical reports.
- Procurement and quality teams - for clear item descriptions and supplier communication.
- Maintenance and training - to prepare consistent manuals, training materials and troubleshooting guides.
- Standards writers and translators - to align multilingual documentation using the official ISO terms and provided German/Italian equivalents.
- Academia and technical education - to teach open-end spinning concepts with authoritative terminology.
Related standards
- ISO 477 - vocabulary for textile machinery and accessories (winders etc.).
- ISO 2205 - terminology for drafting arrangements in spinning machines.
Refer to these for terms that ISO 6173 explicitly excludes.
By using ISO 6173:1982 as a reference, organizations working with open-end spinning machines can improve clarity in specifications, manuals, multilingual documentation and technical communication across the textile value chain.
