Effect of nanoclay on the dyeing ability of PA6 nanocomposite fibers

Surface and Bulk Modification of Synthetic Textiles to Improve Dyeability

“…Nevertheless, because of the interactions between the anions in montmorillonite and the amino groups on the polyamide, the dyeing sites are occupied with the nanoclay. This led to inferior dyeing with acid or metal complex dyes than in the case of the unfilled polymer (Razafimahefa et al, 2005). Our previous study on dyeability of PET/clay nanocomposites stated the following type of interactions between the disperse dye and clay surfaces: -Hydrogen bonding between OH groups of modified clays and the NH 2 and CO groups of disperse dye molecules.…”

“…Blending of polymeric fibers with nanoclays as inexpensive materials is still claimed as cost effective method to enhance dyeability (Geoghegan & Krausch, 2003). Up to now, only two research articles are focused on dyeing properties of polypropylene-and polyamide 6-layered clay incorporated nanocomposites prepared by melt compounding (Razafimahefa et al, 2005;Toshniwal et al, 2007). Toshniwal et al suggested that polypropylene fibers could be made dyeable with disperse dyes by addition of nanoclay particles in polymer matrix (Toshniwal et al, 2007).…”

Relationship between dye sorption and morphology in polypropylene/poly (butylene terephthalate) microfibrillar blend nanocomposite fibers

“…It has been reported that dyeability of polypropylene fiber can be improved by blending with polar polymers (Asiaban & Moradian, 2011Bolhova, Ujhelyiova, Valkova, & Marcincin, 2007;Mirjalili, Moradian, & Ameri, 2011Razafimahefa, Chlebicki, Vroman, & Devaux, 2005Toshniwal, Fan, & Ugbolue, 2007;Ujhelyiova, Bolhova, Oravkinova, Tiňo, & Marcinčin, 2007). Kotek, Afshari, Gupta, Kish, and Jung (2003) indicated that the dye uptake of PP/PA6 blend fibers depends on a number of factors, including the proportion of components and porosity of the fibers.…”

Polymer Nanocomposites: From Synthesis to Applications

“…When the particle size of the same material increases, light rays are scattered and the material becomes translucent (from Wilson et al, 2002). Razafimahefa et al (2005) found out that a polyamide-6/clay nanocomposite fiber yarn dyes itself faster with disperse dyes than unfilled polyamide-6 yarns. Aqueous coatings of intercalated smectite clay particles in poly(N-vinyl pyrrolidone) and poly(ethylene oxide) matrices were found to have the potential to be used in inkjet media with improved receptor properties (Majumdar et al, 2003).…”
