ABSTRACT:
The present invention uses, as a base material, a multi-layer film comprising more than two layers and formed from thermoplastic resins different in melting point from one another. A sectional construction of the multi-layer film or a tape obtained from the multi-layer film is applied to a sectional construction of a fibre without modification, the multi-layer film or tape being formed into the fibre. The invention provides a composite fibre which is much more excellent as compared to a conventional heat adhesive composite fibre by melt spinning, a water-absorbing material using the composite fibre as a base material and a method for the production of the same by the stated simple means.
