It was found that the primary condensation products of melamine with formaldehyde (MF in short) were adsorbed by cellulose. The amounts of MF adsorbed by cellulosic fabris were measured in details and mechanism of the adsorption was discussed. The results are summerized as follows:<br>1. When the molar ratio of formaldehyde against melamine was varied, the quantities of MF adsorbed in cellulose were increased in orders to M2F>M3F>M4F, but in the case of constant molar ratio, MF of higher clouding point was adsorbed much more than MF of lower clouding point, as a result it is assumed that monomer of MF were not adsorbed by cellulose.<br>2. Especially in the case of M2F, Lamgmuir's adsorption equation could be applied and its adsorption energy was calculated as 11.5 Kcal. per mole of dimer of M2F.<br>3. The other reagents, such as the primary condensation products of urea with formaldehyde, methylated methlol melamine and methylol ethylene urea were little adsorded by cellulose.<br>4. There was a tendency to increase wrinkle recovery of cellulosic fabrics by the adsorption of MF.
