Abstract
Cotton fabrics with known free formaldehyde contents were prepared. Free form aldehyde contents of the fabrics were monitored after applying the formaldehyde and after subjecting samples to various experimental conditions that afforded opportunity for loss of the free formaldehyde. In this manner, it was possible to observe changes in formaldehyde contents from exposure of the fabrics to air, to water, and to other fabrics. The influence of time, temperature, moisture, and level of formaldehyde on these changes, and the effect of cellulose crosslinking were determined. The results are discussed with a view to enlarging and extending our fundamental understanding of formaldehyde release from finished cottons and, in particular, the role of free form aldehyde in the fabrics.
