Langues : Anglais (eng) Catégories : Absorption Chaussettes Collants (textile) Colorants réactifs 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).

Yellowness index, Fourier Transform–infrared analysis, scanning electron microscopy analysis and bursting strength tests were applied to samples. The samples treated with laser were dyed in lighter shades than the untreated ones, with all three of the reactive dyes used in the experiments. In general, colour yield values decreased when the resolution and pixel time increased. However, no significant change was observed in washing, rubbing, light and perspiration fastness values. The possibilities of obtaining various patterns on cotton socks dyed with reactive dyes by laser treatment at different resolutions and pixel times were also investigated. According to the results, it was determined that if laser treatment was not applied to some parts of reactive dyed cotton socks, and 10 dpi 100 μs and 20 dpi 100 μs laser was applied to other parts of those socks, then it was possible to obtain patterns with different shades of the same colour on the socks. On the other hand, laser application after dyeing does not have a negative effect on fastness values. After determining the optimum conditions for the laser process, non-see-through tights were produced with cotton yarn on the front and polyester/elastane yarn on the back, and patterns were obtained by applying laser treatment before or after dyeing via sample scale industrial production.

Investigation of the effect of laser technology on the colouring and patterning possibilities in polyacrylonitrile socks / Riza Atav in COLORATION TECHNOLOGY, Vol. 138, N° 4 (08/2022)

To achieve this, laser treatments were applied to acrylic socks at different resolutions (10, 20 and 30 dpi) over various pixel times (80, 100 and 120 µs) before dyeing. To support the findings obtained, tests and analyses, such as Yellowness Index, Fourier Transform–infrared analysis, scanning electron microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, and bursting strength, were also applied to untreated and treated fabric samples. It was found that treatment with laser did not have a significant effect on the basic dye uptake of fibres; nevertheless, the samples treated with laser were dyed slightly lighter than the untreated sample. Furthermore, it was determined that the samples treated at 30 dpi started to melt and the fabric was damaged considerably, but the fabrics treated at 10 and 20 dpi were not affected at all. Another result obtained regarding the use of laser technology in acrylic socks is that if some areas of acrylic socks are not treated with laser, while some other areas are treated with laser at 20 dpi for 100 µs, it is possible to obtain patterns containing two different shades of the same colour on the socks.
