Abstrakt: A report is presented on the role of spatial environment of reaction sites in reversible cross-linking of cotton. The differences between systems in which cross links are in troduced by reaction with difunctional compounds and those in which cross links are formed by reacting substituent groups placed randomly on cellulose chains are discussed. The systems studied were mono- and difunctional dyes on cotton cellulose and acethy drazide disulfide on dialdehyde cotton. Using cupriethylenediamine hydroxide (cuene) insolubility as the criteria for cross-linking, it was'found that the paired placed reaction sites cross-linked more readily than did those placed in a random fashion on the cellulose chain.
