FIBRES HAVING INTERPENETRATING POLYMER NETWORK

摘要

A melt spun fibre or tube having two polymeric fibrous components and containing from 30 to 70 parts by weight of a first component and from 70 to 30 parts by weight of a second component, each component being present in the fibre or wall of the tube as fibrils which are substantially aligned to the axis of the fibre or tube the aligned fibrils being interconnected to each other in a random manner, the interconnections penetrating through the fibrils of the other component such that both components exist in the fibre or tube wall as interpenetrating networks.
