acrylique, Acide L'acide acrylique ou acide acroléïque ou acide prop-2-énoïque est un composé organique de formule brute C3H4O2 et de formule semi-développée CH2=CHCOOH. C'est un acide carboxylique et un alcène vinylique, et se présente comme un liquide incolore à l'odeur âcre.
L'acide acrylique et ses esters, les acrylates, sont utilisés dans la fabrication de matières plastiques, dans les peintures acryliques et dans divers autres polyacryliques qui ont de multiples usages.

| Résumé : |
The influence of grafting and grafting–curing of acrylic acid on the colour fastness of nylon-6 fabric dyed with an acid dye of low wash fastness was investigated. The variables involved in grafting were initially optimised for pristine nylon-6 fabric prior to grafting the same monomer onto the dyed fabrics. The highest graft yield achieved for the pristine and dyed nylon-6 fabrics was 44 and 14% respectively. Grey scale testing and colorimetric analysis revealed that the highest colour fastness and the smallest drop in colour strength belonged to the dyed–grafted–cured nylon-6 fabric. The colour components were measured, and the total colour difference of each sample after five washing cycles was computed. The specific colour difference showed that the implementation of either grafting or grafting–curing processes will alter the reference colour of the dyed fabric. The tensile strength of the grafted and grafted–cured fabrics was respectively 2.7 and 6.3% lower than that of dyed nylon-6. |
