The effects of 0.1g/dl nonionic surfactant solutions on liquid wetting and retention properties of wool fabric are
reported. The 10 different nonionic surfactants (Span 20, Tween 20, 40, 60, 80, 21, 61, 81, 65, 85), wool cloth (EMPA 217), and
wool soiled cloth (EMPA 107) are used in the study. Both EMPA 217 and 107 have water contact angle(Ɵ)>90�, which indicates
that water spreading over a fabric surface and penetration into the fabric rarely occur. However, EMPA 217 and 107 are easily
wetted with perchloroethylene(PCE) having very low values of Ɵ\'s and high values of liquid retention. Water wetting properties are
greatly improved by adding nonionic surfactants into the system. Generally, hydrophilic surfactants which have low number of carbon
atoms or unsaturated hydrophobic structures are effective in improving water wetting of wool fabrics. The water retention of EMPA
217 and 107 in surfactant solutions have positive relations with cosƟ, adhesion tension, and work of adhesion. 40.3% pore volume
of EMPA 217 and 26.1% pore volume of EMPA 217 can be filled with water even when we assume cosƟ=1 (Ɵ=0�). |
