EN 14278-1:2004 (E) 3 Foreword This document (EN 14278-1:2004) has been prepared by Technical Committee CEN/TC 248 “Textiles and textile 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of an identical text or by endorsement, at the latest by November 2004, and conflicting national standards shall be withdrawn at the latest by November 2004. Annex A is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries 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, Switzerland and United Kingdom.

EN 14278-1:2004 (E) 4 Introduction The aim of this method is to determine the stickiness potential of cotton fibres by simulating the negative effects of this characteristic during the spinning process. Origins of stickiness are not studied.
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 cotton fibre stickiness": • Part 1: Method using a manual thermodetection device • Part 2: Method using an automatic thermodetection plate device • Part 3: Method using an automatic rotating drum device SIST EN 14278-1:2004



EN 14278-1:2004 (E) 5 1 Scope The standard describes a manual technique to simulate the tendency of cotton fibres to stick to textile working surfaces. Test specimens can be raw cotton fibre (fibre sampled e.g. from a bale), or opened fibre, slivers, etc. 2 Normative references This 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 listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 20139 Textiles - Standard atmospheres for conditioning and testing (ISO 139:1973)
3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 stickiness level number of sticky points indicating the incidence of cotton fibre
stickiness 3.2 thermodetection action of revealing sticky points through the combined application of heat and pressure 3.3 sticky points entanglement of fibres or individual fibres that are attached to a working surface as a result of the inherent stickiness of the cotton 3.4 ensemble upper and lower aluminium foils enclosing a fibre sample 3.5 remover device to take away the non sticking fibres from the counting surface 4 Principle A fibre web, whose surface area and mass are fixed, is placed between two sheets of aluminium foil and pressed at two pressure levels applied successively at different temperature settings to reveal sticky points. The sticky points are then counted to evaluate the level of stickiness. SIST EN 14278-1:2004
