The natural logarithm of the rate constant of dye transfer from dyed fabric to white cloths and that of the equilibrium constant were linearly related to the reciprocal of the rubbing force, which was given by the product of the weight and the friction coefficient between the dyed fabric and white cloth. Two straight lines were obtained, in spite of the variety of white cloths used, and they converged in the low rubbing force range. The results show that the dry rubbing fastness with various white cloths is primarily influenced by the friction coefficient and rubbing force rather than by the types of textile fibre or fabric.

Improvement of the standard method for assessing colour fastness to wet rubbing / Keiko Suganuma in COLORATION TECHNOLOGY, Vol. 131, N° 5 (10/2015)

Langues : Anglais (eng) Catégories : Coton Le coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles). Essais dynamiques Résistance aux frottements humides Solidité de la couleur Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : Colour fastness to rubbing is evaluated by the degree of staining of a standard adjacent cotton cloth. However, some kinds of dye usually stain other textiles to a greater extent than cotton under wet conditions. In this work, rubbing fastness tests were carried out with various kinds of adjacent cloth in order to examine the factors affecting the wet rubbing fastness, and a more practical evaluation method using adjacent rubbing cloth was proposed. Dye transfer from the dyed fabric to the adjacent cloth depended on the affinity of the dyes for the fibre material of the dyed fabric and the adjacent cloth under wet conditions, in addition to the friction coefficient between the fabrics. A standard adjacent cloth should have a high staining property. The nylon staple cloth is preferred for fabrics dyed with vat, disperse, and acid dyes because it receives the most dye from rubbing with them.
