The absorption and spreading of aqueous finishing fluids onto textile fiber surfaces

摘要

The mechanism of ink absorption at the fiber surface, and also the penetration of ink into the fiber structure are key phenomena of textile finishing technology. To obtain high quality finishes, it is important to understand the relative importance of the parameters that define the absorption rate and spreading ratio of droplet shaped fluid elements that impact the textile surface.rnA simple model that combines Darcy's Law and harmonic droplet oscillator frequency forms a precursor to further advanced Dissipative Particle Dynamic (DPD) modeling. Experimental data for several combinations of textile and model fluids are presented. The key technical challenges to be addressed and overcome in the near future are discussed.
