Method and device for manufacturing materials from hydrophobic hollow natural fibres, and use thereof

摘要

The invention relates to a method for processing hydrophobic hollow natural fibers, in particular vegetable hollow natural fibers and more particularly kapok fibers, to form material, and to a material obtainable by such a method. The invention furthermore relates to “the use of such aτnaterial as absorption medium for apolar substances and a device for performing the method.

1. Method for manufacturing an apolar sorption material, comprising:
providing hydrophobic hollow natural fibres with a hemicellulose content of at least 10% by weight, heating at least a part of the hollow natural fibres to a temperature between 160° C. and 220° C., and compressing at least a heated part of the treated hollow natural fibres; wherein, at least during the compression, the temperature of at least the heated part of the treated natural fibres is between 160° C. and 220° C., and wherein at least a part of the hollow natural fibres is wetted with water at least during the heating.
