“…Improved dyeability performance of the PET/organoclay nanocomposite filaments could be attributed to void space generation by the addition of montmorillonite‐type clay into the fibre, as confirmed by our previous work and by Gashti and Moradian . A phthalimide carrier was used in this study, and it was shown that a phthalimide carrier had a strong plasticising effect on the PET fibre, i.e.…”

“…In our previous work , we prepared PET/montmorillonite nanocomposite filaments by using two different types of clay which were modified using an ammonium surfactant, and we investigated their physical and dyeing properties. Dyeings were performed at 100 °C (with/without a carrier) and 120 °C (without a carrier).…”

“…We have shown that PET/organoclay nanocomposite filaments exhibited only a slightly enhanced dyeability only in the presence of a carrier under atmospheric dyeing conditions. In the present study, a new surfactant was synthesised and used for organomodification of raw clays, in addition to the existing one from our previous study , for the purpose of comparing different organophilic surfactants on dyeability. Moreover, in order to be able to determine a possible most suitable dyeing temperature for PET/organoclay nanocomposite filaments that might enable the elimination of or at least a reduction in carrier usage, dyeings were carried out at 100, 110, and 120 °C both in the absence and in the presence of a carrier.…”

This study deals with the generation of poly(ethylene terephthalate)/organoclay nanocomposite filaments by the melt‐spinning method and with the investigation of their morphological and dyeing properties. Different montmorillonite types of clay (Resadiye and Rockwood) were modified using different intercalating agents, and poly(ethylene terephthalate) nanocomposite filaments containing 0.5 and 1 wt% organoclays were prepared. Afterwards, the filaments were dyed with two disperse dyes (Setapers Red P2G and Setapers Blue TFBL‐NEW) at different temperatures (100, 110, and 120 °C) in the absence/presence of a carrier. Organoclays and poly(ethylene terephthalate)/organoclay nanocomposites showed an increased d‐spacing between clay layers. Irrespective of clay and surfactant type, poly(ethylene terephthalate)/organoclay nanocomposite filaments dyed at 120 °C in the presence of only a very small amount of carrier showed appreciable dyeability in comparison with neat poly(ethylene terephthalate). The dyeability of the organoclay‐containing poly(ethylene terephthalate) samples was found to be better in spite of having increased degrees of crystallinity. Moreover, the colour fastness properties of the clay‐containing samples were not affected adversely.

“…A good dispersion of layered silicates in PU elastomer nanocomposites has been found to improve mechanical properties, thermal stability, gas barrier properties and flame retardancy, etc. Although several studies have reported on the dyeing of clay or layered‐silicate nanocomposites of polypropylene , polyethylene terephthalate (PET) , polyamide 6 , polylactic acid (PLA) and PU , there is almost no literature reporting on the dyeing of PU/clay in filament form. Therefore, in the current study PU filaments have been modified by the incorporation of nanoclay to increase their dyeability with acid dye, basic dye and reactive dye.…”

Polyurethane/clay nanocomposite (PUCN) filaments were spun by the dry‐jet‐wet spinning method. To prepare the PUCN filaments, 0.25, 0.50 and 1% of nanoclay on the weight of polyurethane were incorporated in the polyurethane dope. The interaction between clay and polyurethane was analysed by attenuated total reflectance–Fourier Transform‐infrared (ATR‐FTIR) spectroscopy. The structure and morphology of the PUCN filaments were analysed by wide‐angle X‐ray diffraction (WAXD) and transmission electron microscopy (TEM). Both the neat polyurethane and the PUCN filaments were dyed with different acid, basic and reactive dyes. The neat polyurethane filaments exhibited poor dyeability with all three classes of dyes. By contrast, the PUCN filaments showed a significantly higher dye uptake with all of the dyes used. Furthermore, the dye uptake increased significantly as the percentage of clay in the filaments increased, as indicated by the increase in the K/S values of the dyed filaments. The dyeing mechanism with all three dyes, as well as the increased dyeability of the PUNC filaments in comparison to those of the neat polyurethane filaments, was discussed.

“…Özen and Güneş stated that organoclay layers formed a temporary network within the PET polymer chains, and this led to the development of the crystalline order and amorphous orientation and to decrease the degree of crystallisation. It was observed that these effects depended on the size of the organoclay layers, the relationship between the polymer chain and organoclay, and the decrease in the crystallinity in the filaments where the partially orientated structure is larger [30].…”

Today, the production of polymeric nanocomposite materials is one of the most important research fields. In this study, it was aimed to investigate the effect of organoclay particles on recycled polyester (rPET) fibre properties. In the literature, the studies mostly concerned with the engineering plastic applications, and hence the investigations were done on pellet and injection-moulded rPET/organoclay nanocomposite samples. Actually, fibre application is the most important market for PET wastes, but unfortunately, there are only a few papers regarding rPET/organoclay composite fibre properties. In the study, rPET/organoclay nanocomposites were prepared by melt intercalation process with different modified organoclay types (3 wt-%), and multifilament fibres were spun by the melt spinning method. Morphological and thermal properties of nanocomposites and surface structure, tensile, and thermal stability properties of the fibres were tested. The results indicated that the distribution of clay particles and organoclay types had a significant influence on various fibres properties.
