Sublimation transfer printing of polyester is a well established technique. For successful transfer printing of PET/cotton blends, however, it is necessary to provide a suitable pretreatment to impart disperse dye affinity to the cotton component. This paper reports attempts to synthesize a crosslinking agent based on the reaction product of melamine formaldehyde/polyethylene glycol 200. The fabric was treated with this product by pad-dry application; curing and transfer printing were simultaneous. The performance of the synthesized product in terms of dye transfer, wash and light fastness, and its effect on physical properties of the transfer printed fabric was compared with the commercial melamine formaldehyde resin.
We investigated the influence of carbon materials on the properties of adhesives. With the aim of the development of conductive and mechanically improved adhesives, different types of multi-walled carbon nanotubes (MWNT), single-layer graphene, graphene nanoplatelets, graphite, and carbon black were dispersed into an epoxy adhesive. For inserting particles within the viscous matrices and to obtain homogenous and stable dispersions, two different methods namely a three-roll mill and a dual asymmetric centrifuge have been compared The results demonstrate that filling epoxies with carbon nanoparticles improves the conductivity differently. Measuring the electrical resistivity of MWNT-filled composites resulted in an electrical percolation starting underneath 0.1 wt.%. Further, with increasing the MWNT content, conductivity sharply increases. In contrast to the MWNT composites, other carbon nanoparticles require a higher filling content to reach similar values. With a filling ratio up to 17.0 wt.% for ACS graphene nanoplatelets 2–10 nm and the filling of 3.0 wt.% with MWNTs from Nanocyl, the lowest volume resistivities have been reached
