| Research Abstract |
The physical properties of tropical wool fabrics were investigated. The samples were woven with yarn from loose fibers which were treated with a water soluble multifunctional epoxide, i. e., glycerol polyglycidyl ether (GPE) in an aqueous media catalyzed with a reductive agent (Na_2S_2O_5) in the presence and absence of saturated NaCl.
The resin treatment stiffened the fabrics somewhat and decreased the ability to regain moisture a little. Scanning electron microscopy (SEM) has revealed a difference in the abrasive breakdown pattern between the GPE/sat. aq. NaCl treated wool and the untreated one. A good state of hydrophobic nature preservation of the scale surface after treatment has been confirmed by soiling measurements of the wool with an oleophilic mixture/carbon black complex. There were fewer carbon black particles deposits in surfactant solution on the untreated and GPE/sat. aq. NaCl treated wool than on the GPE/H_2O treated one.
