Diffusion Behaviors of Disperse Dye to PET Film from Print Paste Using Film-Roll Method

Kinetic of Disperse Dye on Compounded PET Polyethylene Terephthalate Using Hyperbranched Polymeric Additive as A Nanomaterial

This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients a...

Microstructure formation via roll-to-roll UV embossing using a flexible mould made from a laminated polymer–copper film

Roll-to-roll large format UV embossing processes aim to revolutionize the manufacturing of functional films, with the ability to process a large area at one time, resulting in high throughput and cost reduction. In this paper, we present the experimental results obtained during the process development for roll-to-roll large format UV embossing. Flexible moulds were fabricated from a hybrid film...

Film-pore diffusion modeling for sorption of azo dye on to exfoliated graphitic nanoplatelets

Exfoliated graphitic nanoplatelets (xGnPs) have been utilized as a potential adsorbent for toxic textile dye Acid Orange 7 (acid dye). The effects of major variables governing the efficiency of the process, such as temperature, initial dye concentration and pH are studied. The kinetic measurements have been used for determining the specific rate constant, confirming the applicability of pseudo ...

Flexcellence : towards Roll-to-roll Mass-production of Low Cost Thin Film Silicon Solar Cells

We report on the “mid-term” results obtained in the frame of the European FLEXCELLENCE project (www.unine.ch/flex). FLEXCELLENCE aims at developing the equipment and the processes for cost-effective roll-to-roll production of high-efficiency thin-film modules, based on amorphous (a-Si:H) and microcrystalline silicon (μc-Si:H). Eight partners, with extended experience in complementary fields ran...
