It is shown that the decrease in tearing strength of wool fabrics due to treatment with boiling water or buffer solutions (pH 2-10) was enhanced if the fabric had been previously extracted with chloroform/methanol. The increased susceptibility of the wool to high-temperature or alkali damage may have been due to the extraction of components from the cell-membrane complex as is known to occur during chloroform/methanol treatments. Extraction of wool fabric with other solvents also caused decreases in tearing strength when the wool was subsequently treated with boiling aqueous solutions. These observations may have important implications for the study of wool damage during dyeing. The breaking load of fabrics boiled in buffer of pH 7 was not decreased by prior extraction of the samples with any of the solvent systems studied. Yellowing of the wool fabric owing to boiling in aqueous solutions was unaffected by the solvent pretreatments. [ABSTRACT FROM AUTHOR] |
