Notes:
Residues remaining after drying and curing cotton fabric with either sodium bisulfate or zinc nitrate and N-methylolpyrrolidone, a monofunctional model durable press agent, have been quantitated by high performance liquid chromatography. The residues were identified as pyrrolidone, N-methylolpyrrolidone, N,N′-methylene-bis-2-pyrrolidone, and N,N′-(oxydimethylene)bis-2-pyrrolidone. The two catalysts fixed approximately the same amount of the N-methylolpyrrolidone to cellulose, but generated different ratios of the extractable residues. A comparison of the levels of these residues that are capable of releasing formaldehyde is given. The dominant residue from the NaHSO4 treatment was N-methylolpyrrolidone, while zinc nitrate generated more N,N′-(oxydimethylene)bis-2-pyrrolidone.
