PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Polyamide microfibres were dyed using disperse dye in the presence and absence of methyl methacrylate. The dye uptake and colour strength in the presence of methyl methacrylate were substantially higher than in its absence. Scanning electron microscope analysis showed that there was a dye layer on the microfibre surface formed by methyl methacrylate adsorption after dyeing. Differential scanning calorimetry measurement showed that the glass transition temperature of the polyamide microfibre reduced following methyl methacrylate treatment. The ultimate consequence of all these functions was to facilitate diffusion of dye molecules into the microfibre, thereby increasing the colour strength. The wash fastness of the dyed samples was identical for the two different dyebaths, although there were slight differences in the staining grades. The rub fastness of the methyl methacrylate-treated samples was improved by ca. half a grade. The methyl methacrylate had no effect on light fastness. |
