Textiles - Determination of cotton fibre stickiness - Part 2: Method using an automatic thermodetection plate device

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.

Textilien - Bewertung der Klebrigkeit von Baumwolle - Teil 2: Verfahren mit dem automatischen Platten-Thermodetektionsgerät

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

Textiles - Détermination du collage des fibres de coton - Partie 2: Méthode utilisant un dispositif automatique de thermodétection à plateau

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 14278-2:2004 (E)3ForewordThis document (EN 14278-2:2004) 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 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, Switzerland and United Kingdom.SIST EN 14278-2:2004

EN 14278-2:2004 (E)4IntroductionThe aim of this method is to provide an indication of the stickiness potential of a sample of cotton fibres bysimulating the tendency of "contaminated" cotton to stick to working surface during the spinning process. Thistest method does not distinguish between the various types of contamination which may cause stickiness.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 14278-2:2004

EN 14278-2:2004 (E)51 ScopeThis standard describes an automatic technique to simulate the tendency of "contaminated" cotton fibres tostick 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.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. For dated references, subsequent amendments to or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision. For undated references thelatest edition of the publication referred to applies (including amendments).EN 20139Textiles - Standard atmospheres for conditioning and testing (ISO 139:1973).3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.3.1stickiness levelnumber of sticky points indicating the severity of cotton fibre stickiness3.2sticky pointsentanglement of one or more fibres that become attached to a working surface as a result of contamination ofthe cotton by sticky substance3.3thermodetectionaction of revealing sticky points through the combined application of heat and pressure3.4padthick homogeneous web of fibres formed by a special fibre opening and condensing device3.5removerdevice for removing the non sticking fibres from the aluminium foil4 PrincipleA weighed fibre sample is processed through an opener to obtain a pad. This pad is placed on an aluminiumfoil and subjected to pressure by two separate pressure plates, one after the other. 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
