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. 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 fibres or individual fibres that are attached to a working surface as a result of contaminationof the cotton by sticky substance3.3thermodetectionaction of revealing sticky points through the combined application of heat and pressure3.4cotton webthin homogeneous cotton fibre web formed by a special micro-card opening device3.5removerdevice to take away the non sticking fibres and the cotton web from the rotating drum4 PrincipleA weighed specimen of cotton fibres is formed by hand into a short sliver and delivered by a conveyer to amicro card, where it is opened into a fine web and fed and pressed between two rotating drums maintained ata defined temperature.
