ISO 8119-1:1989

Overview

ISO 8119-1:1989 - "Textile machinery and accessories - Needles for knitting machines - Terminology - Part 1: Latch-type needles" is an international terminology standard published by ISO/TC 72. It defines the names and descriptive terms used for latch-type needles used in knitting machines, providing concise definitions and corresponding illustrations. The standard presents terminology in English, French and Russian (with German equivalents in Annex A at the request of the German member body). It is the first part of the ISO 8119 series covering needle terminology.

Key topics

• Multilingual needle terminology: official terms in English, French and Russian; German equivalents in Annex A (informative).
• Definition of a latch-type needle: flat or round section, hook-shaped head and a reciprocating latch on a fixed pivot that opens and closes during the loop-forming cycle.
• Illustrated nomenclature of principal parts and features, including:
  • Butt (protrusion for cam guidance or to hold the needle)
  • Butt dimensions and variants (width, height, low/high butt, multiple butts)
  • Crimp (guidance in front of the butt)
  • Back shank and its types (with/without back shank, single/double)
  • Shank (blade) features and transfer elements (clips, transfer milling, back transfer slot)
  • Needle orientation and sides (top, bottom, left, right)
  • Groove, cheek, throat, hook and other detailed elements
• Clear, figure-referenced vocabulary to ensure consistent use of terms across technical documentation, drawings and communication.

Applications and users

ISO 8119-1 is practical for organizations and professionals involved with knitting machinery and textile production:

• Needle manufacturers and tooling designers - for consistent part descriptions and production specifications.
• Knitting-machine OEMs and component suppliers - to align documentation, assembly instructions and spare-parts catalogs.
• Quality assurance and procurement teams - to specify needle types and verify conformity of delivered parts.
• Machine maintenance, repair technicians and knit engineers - for accurate identification of needle parts and guidance on interchangeability.
• Standards writers, translators and technical authors - for harmonized multilingual terminology in manuals and technical literature.
