FIBRE CAVE DI CHITOSANO E PROCEDIMENTO PER IL LORO OTTENIMENTO |
摘要 |
Hollow chitosan fibres for use in ultrafiltration processes are described, and which can be plasticized by the addition of glycerin such that they contain this latter in a quantity variable between 0.5 and 5% by weight with respect to the polymer. Said fibres are prepared by the wet spinning of acid chitosan solutions, using an alkali solution as the external fibre coagulant and a gaseous phase containing a basic gaseous component as the internal fibre coagulant. |
