“…Therefore an analysis was made of the diffusion of PHMB into the textile. To quantify the characteristic diffusion time for PHMB in the textiles, the approach of Groot Wassink, 12 Nierstrasz et al, 15 and Warmoeskerken et al 16 was used. Assuming that the PHMB molecule is a sphere, the diffusion constant D can be calculated using Eq.…”

Adsorption and desorption studies were done of polyhexamethylene biguanide (PHMB) onto two different types of textile fiber surfaces. Based on these studies and mathematical modelling, the rate constants were calculated. Two different experimental conditions were used to simulate laundering, namely wet-to-wet and dry-to-wet. The model PHMB surface concentrations showed that the model can be used to describe the adsorption kinetics on cotton and cotton-polyester blends with reasonable accuracy.

“…This can theoretically be achieved by flowing the enzyme solution through the fabric. However, the flow resistance in the intrayarn pores is much higher than the resistance in the inter-yarn pores, the bulk of the liquid will flow along the yarns instead of through the yarns [15,16]. Apparently, cotton scouring with enzymes is a diffusion controlled process.…”
