Abstract (en)
[origin: EP0047795A2] The fibre has an amorphous structure or a partially oriented molecular structure where the surface structure is part of a foamed layer which envelopes a fibre core which is essentially free of pores. The pores are perpendicular to the surface and their cross-section, having a diameter of from 0.01 to 0.5 mu , covers from 1 to 99% of the total surface area.
