Résumé : |
A new polyurethane phosphate ester (PUP-2) was successfully synthesized based on a nonionic amphiphilic polyurethane (PU-2). The structures and properties of PU-2 and PUP-2 were characterized by FTIR and surface tensiometer. The fatliquoring experiments were carried out in three different groups (treated with PUP-2 alone, with the complex of hexadecyl phosphate ester (SU) and PUP-2, or with the complex of SLP, PUP-2 and other commercialized fatliquoring agents, respectively). The physical and organoleptic properties of the resultant leathers were investigated and SEM was carried out in the study of fiber splitting. The leathers treated in the three different fatliquoring experiments all did not have fatty spew defect. Furthermore, the resultant leathers treated with PUP-2 alone or with the complex of SLP and PUP-2 had the advantage of resistance to yellowing. This new phosphate ester meets the requirements for the leathers with a good performance in resistance tu yellowing and avoiding fatty spew defect. |
