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.

EN 14278-3:2004 (E)3ForewordThis document (EN 14278-3:2004) has been prepared by Technical Committee CEN/TC 248 “Textiles andtextile products”, the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of an identicaltext or by endorsement, at the latest by September 2004, and conflicting national standards shall bewithdrawn at the latest by September 2004.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerlandand United Kingdom.SIST EN 14278-3:2004

EN 14278-3:2004 (E)4IntroductionThe aim of this European Standard is to provide an indication of the stickiness potential of a sample of cottonfibres by simulating the tendency of "contaminated" cotton to stick to working surface during the spinningprocess. This test method does not distinguish between the various types of contamination which may causestickiness.Results of this method are not directly related to the determination of sugar content.This standard consists of the following methods, under the general title "Textiles - Determination of cottonfibre stickiness":· Part 1: Method using a manual thermodetection device· Part 2: Method using an automatic thermodetection plate device· Part 3: Method using an automatic thermodetection rotating drum deviceSIST EN 14278-3:2004

EN 14278-3:2004 (E)51 ScopeThis European Standard describes an automatic technique to simulate the tendency of "contaminated" cottonfibres 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.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text, and the publications are listedhereafter.
