  Abstract

The approach of using reverse micelle with nonionic surfactant (poly(ethylene glycol), PEG)) as building block has been employed to investigate dyeability of wool fabrics with reactive dyes in a one-bath non-aqueous solvent system. Three colours were used and they were encapsulated in the core of the PEG-based reverse micelle under optimised process parameters (i.e. (i) Solvent volume to wool fabric weight ratio (v/w)=10:1; (ii) Surfactant/water mole ratio=0.04:1; (iii) Surfactant/co-surfactant mole ratio=1:8; (iv) Volume of water-pool for dye=0.5 ml; (v) Dyeing time=50 minutes; and (vi) Dyeing temperature=88 oC). Comparison of non-aqueous and aqueous-based (water-based) dyeing was conducted in terms of dyeability as reflected by colour yield and colour fastness properties. Experimental results revealed that the reverse micellar non-aqueous dyeing system can provide a better dyeing performance than aqueous-based dyeing system.
