POLİKARBOKSİLAT ESASLI DİSPERGİR MADDELERİNİN SENTEZİ VE DİSPERS BOYA İLE POLİESTER KUMAŞIN BOYAMASINDA KULLANIMI
Project no. 22211 · Status: Kapanmış · 2020
Summary
The demand for textile products such as fabrics and carpets increases rapidly due to reasons such as population growth and increasing quality of life. Polyester is the most widely used synthetic fiber in the textile industry to meet this demand. Disperse dyestuffs are the only dye class that can dye polyester fibers, and higher polyester fiber production leads to higher disperse dyestuff consumption. One of the most important auxiliary materials used in dye liquor in polyester dyeing is dispersant. In this project, it is aimed to design and synthesize new polycarboxylate-based dispersing agents to be used in the dyeing process of polyester. Raman Spectroscopy and GPC analyzes of these synthesized dispersive substances were performed and dye suspensions were prepared with these dispersive substances under different conditions. The chemical properties of the prepared dye suspensions such as turbidity, solubility, particle size, molecular weight, type of side chain and functional groups and dispersion abilities were analyzed. The dyeing experiments were carried out with dye suspensions, where optimum results were obtained. After dyeing, remission (%R) values, color yield (K/S), CIE L*a*b* values, color difference (?E), ?max values of the samples were measured, and fastness properties such as light, washing and rubbing fastness were tested. It was determined that the developed new dispersing agents at the end of the project had high dye efficiency and fastness, good dyeing smoothness, low cost and environment friendly.
