ISO 4105:1978

Overview

ISO 4105:1978 is an international standard published by the International Organization for Standardization (ISO) that focuses on wires for flexible card clothings used in textile machinery and accessories. This standard is specifically designed to lay down the dimensions, shapes, and sections of wires used in flexible card clothings, which are critical components in the carding process during textile manufacturing.

Developed by ISO Technical Committee ISO/TC 72, which specializes in textile machinery and accessories, ISO 4105:1978 ensures uniformity and compatibility for card wires worldwide. The standard provides detailed tables of values for wire sizes and sections, supporting various wire profiles including round, biconvex, ovoid, triangular, and flat shapes.

Key Topics

• Wire Dimensions and Sizes
  ISO 4105 defines precise measurements for card wire diameter and cross-sectional dimensions, ensuring consistency in manufacturing and operational performance.

• Wire Shapes and Sections
  The standard categorizes wires by shape – including round, biconvex, ovoid, triangular, and flat sections – addressing different functional requirements for card clothings.

• Size Equivalences and Gauge Numbers
  It includes equivalences between metric dimensions (in mm) and gauge numbers used in various regions, facilitating international trade and quality control.

• Material Specifications
  Although primarily focused on geometric characteristics, ISO 4105 indirectly influences the selection of suitable materials for optimal card wire performance.

• Practical Application Guidelines
  The tables and specifications support manufacturers and machine operators in selecting and replacing wires that fit established dimension criteria.

Applications

• Textile Carding Machines
  Wires standardized by ISO 4105 are used in flexible card clothings, components essential for separating and aligning fibers in carding machines during yarn production.

• Quality Control and Inspection
  Manufacturers of textile machinery and wire producers apply ISO 4105 for quality assurance, ensuring wires meet required dimensional tolerances.

• Interchangeability of Components
  Machine maintenance teams benefit from the standard through reliable replacement parts, minimizing downtime caused by incompatibility or improper wire sizing.

• Research and Development
  Textile engineers utilize the standard when designing new card clothing materials or modifying existing carding processes for enhanced fiber handling.
