(Main)Textiles - Determination of cotton fibre stickiness - Part 2: Method using an automatic thermodetection plate device
- Abstract
This 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, etc.

SIST EN 14278-2:2004 is the Slovenian national adoption of EN 14278-2:2004 from CEN. It specifies an automatic thermodetection plate method for determining cotton fibre stickiness by simulating how contaminated fibres stick to working surfaces in textile machines. The method is intended for raw cotton fibre, opened fibre, slivers and similar samples used in textile testing and spinning control.
What does SIST EN 14278-2:2004 specify?
SIST EN 14278-2:2004 covers an automatic way to assess the stickiness potential of cotton fibres. In practice, it is used to simulate fibre sticking on surfaces such as card clothing, drafting rollers and crush rolls, so the result is relevant to processing behaviour rather than to a chemical analysis.
The document is organized into scope, normative references, terms and definitions, principle, apparatus, conditioning atmosphere, specimen preparation, procedure, calculation and expression of results, and test report. It also includes informative Annex A on statistical information.
The introduction explains that the method gives an indication of stickiness potential, does not distinguish between different contamination types, and is not directly related to sugar content.
What are the key requirements of SIST EN 14278-2:2004?
Principle and apparatus
The test works by preparing a fibre pad from a weighed sample, pressing it first with a heated plate and then with a plate at ambient temperature, and then counting the sticky points left on aluminium foil. That sequence matters because the result depends on controlled heat, pressure and subsequent image analysis.
- The automatic system has five stations on a conveyor: pad preparation, heated pressing, ambient pressing, pad removal, and image analysis.
- The heated plate is kept at 53 ± 2 °C and both pressure steps apply 1700 ± 150 N for 25 ± 2 s over the specified contact area.
- The image analysis device records sticky points on the foil and the software counts and measures them.
- The balance, aluminium foil and cleaning arrangement are specified so that sample handling and residue removal do not distort the count.
Sampling, conditioning and specimen preparation
SIST EN 14278-2:2004 requires conditioning in the standard atmosphere defined in EN 20139. This keeps moisture effects under control, which is important because cotton behaviour changes with humidity.
- Condition the laboratory sample for at least 24 h.
- Prepare three test specimens by taking fibre tufts at random from the laboratory sample.
- Each specimen must weigh between 3.0 g and 3.5 g.
- If the cotton has high moisture content, pre-drying may be needed so that conditioning starts from the dried state.
Procedure and reporting
SIST EN 14278-2:2004 expects the operator to follow the supplier’s instructions for cleaning, stabilising, calibrating and using the software. That helps keep the conveyor, plates, optics and cleaning fabric in a repeatable state.
- Place the aluminium foil bright side up and avoid wrinkles.
- Run the automatic sequence from pad formation to image capture and counting.
- Repeat the test for all three specimens.
- Report the number of sticky points for each specimen and the arithmetic mean of the three results.
What terms does SIST EN 14278-2:2004 define?
- Stickiness level - the number of sticky points used to express how severe the cotton fibre stickiness is.
- Sticky point - an entanglement of one or more fibres that remains attached to a working surface because of sticky contamination.
- Thermodetection - the action of revealing sticky points by combining heat and pressure.
- Pad - a thick, homogeneous web of fibres formed by the opening and condensing device.
- Remover - the device used to remove non-sticking fibres from the aluminium foil.
Who uses SIST EN 14278-2:2004?
SIST EN 14278-2:2004 is used by textile testing laboratories, cotton spinning operations and quality control teams that need a repeatable way to compare cotton samples for stickiness. It is also useful for buyers, mill technicians and process engineers who need to judge the risk of fibre sticking on machine surfaces before or during processing.
Which standards are used with SIST EN 14278-2:2004?
- EN 20139 - provides the standard atmosphere for conditioning and testing.
- EN 14278-1 - the manual thermodetection device method in the same series on cotton fibre stickiness.
- EN 14278-3 - the automatic thermodetection rotating drum device method in the same series.
What does the SIST EN 14278-2:2004 document contain?
The document gives the full test sequence for an automatic plate-based stickiness check, from fibre pad formation to image capture and software counting. It specifies the conveyor arrangement, plate temperatures, pressures, foil handling, cleaning method and the sample conditioning and weighing steps.
It also sets out the required test report items: the standard reference, sample identification, any sampling procedure used, any deviations from the procedure, and the individual and mean sticky-point counts. Annex A adds statistical guidance, including the note that sticky-point counts are not normally distributed and may need transformation or log-linear analysis.

The first pressure plate ismaintained at a temperature significantly higher than ambient. The second pressure plate is maintained atambient temperature. The pad is removed from the foil and all loose fibres are cleaned away. Any fibreentanglements left sticking to the foil are noted and counted as sticky points. All the operations and resultanalysis are computer controlled.SIST EN 14278-2:2004
