Textiles - Determination of cotton fibre stickiness - Part 3: Method using an automatic thermodetection rotating drum device

This European Standard describes an automatic technique to simulate the tendency of "contaminated" cotton fibres to stick to working surfaces of textile machines (e.g. card clothing, drafting rollers, crush rolls).
Test specimens can be raw cotton fibre  (fibre sampled, e.g. from a bale), or opened fibre, slivers.

Textilien - Bewertung der Klebrigkeit von Baumwolle - Teil 3: Verfahren mit dem automatischen Rotations-Thermodetektionsgerät

Diese Europäische Norm legt ein automatisches Verfahren zur Simulierung der Neigung von �belasteten" Baumwollfasern fest, an Arbeitsflächen von Textilmaschinen (z. B. Kardengarnitur, Streckwerken, Quetschwalzen) zu kleben.
Dieses Verfahren gilt für Messproben von Fasern von Rohbaumwolle (z. B. aus einem Ballen entnommene Fasern) oder geöffnete Baumwollfasern, Baumwollfaserbänder.

Textiles - Détermination du collage des fibres de coton - Partie 3: Méthode utilisant un dispositif automatique de thermodétection à tambour rotatif

La présente Norme européenne décrit une technique automatique permettant de simuler la tendance des fibres de coton « contaminées » à coller aux surfaces de travail des machines textiles (par exemple, garniture de carde, rouleaux étireurs, cylindres broyeurs).
Les éprouvettes peuvent être constituées de fibres brutes de coton (fibres échantillonnées à partir d'une balle, par exemple), de fibres ouvertes, ou de rubans, etc.

Overview

EN 14278-3:2004 (CEN) specifies an automatic thermodetection rotating drum method for determining cotton fibre stickiness. The standard simulates how “contaminated” cotton fibres adhere to textile machine surfaces (e.g., card clothing, drafting rollers, crush rolls). Test specimens may be raw bale cotton, opened fibre or slivers. The method uses a micro-card to form a thin cotton web, compresses the web between heated rotating drums, and detects sticky points with a laser-based thermodetection system.

Keywords: EN 14278-3, cotton fibre stickiness, thermodetection, rotating drum, textile testing, CEN.

Key topics and requirements

  • Principle: Create a web from a weighed specimen, press it between two heated steel drums, remove loose fibres, and detect remaining sticky points optically.
  • Apparatus:
    • Micro-card for forming a consistent cotton web (target mass ~4.0 g/m²).
    • Pair of smooth hardened steel rotating drums (temperature controlled, nominal rotation speed ~100 min⁻¹).
    • Heating, cleaning brushes, scraper blades and wiper system to avoid repeat detection.
    • Laser-photodiode detection with software algorithm to count and size sticky points.
    • Balance accurate to 0.1 g for specimen masses (3.5 ± 0.2 g).
  • Atmosphere and conditioning: Use standard conditioning and testing atmosphere as per EN 20139 (ISO 139), and condition samples at least 24 h.
  • Specimen preparation: Form each test specimen into a sliver (~30 cm length) and perform three replicate tests per sample.
  • Results and reporting:
    • Express sticky points as number per gram (mean of three specimens).
    • Sticky points may be classified into size categories (size 1 to size 5).
    • Report any deviations, sample identification and test results.

Practical applications & users

  • Textile mills, spinning and ginning operations assessing processing performance.
  • Quality laboratories and R&D teams evaluating contamination-related processing risks.
  • Equipment manufacturers and service labs validating cleaning/conditioning treatments, machine settings, or new cotton lots.
  • Use-cases include predicting tendency for fibre deposits on machines, optimizing cleaning regimes, and screening cotton lots for stickiness potential.

Limitations & notes

  • The method does not distinguish contamination types (e.g., sugars vs. other tacky substances) and results are not directly correlated to sugar content.
  • Statistical behavior of sticky counts is non-Gaussian; transformations (e.g., square-root) or log-linear models may be needed for analysis.

This standard provides a repeatable, automated approach for assessing cotton stickiness potential, supporting process control and quality assurance in textile production.
