Title:
【発明の名称】吸収性フォーム材料の親水化法
Document Type and Number:
Japanese Patent JP3280973
Kind Code:
B2
Abstract:
Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with sorbitan monolaurate. Thus, a polymeric foam can be prepared or treated with sorbitan monolaurate and thereafter dried to leave a substantially uniformly distributed residue of sorbitan monolaurate on the internal foam surfaces. The resulting treated foams are rendered hydrophilic and are thus suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.
