Abstract (en)

[origin: EP0136659A2] A wet-degradable fiber having a covering resin layer is described. The moisture permeability (R) of a resin forming the covering layer is at least 2.5 g/m<2>.24 hours as determined at a relative humidity difference of 0% and 90% with respect to a thickness of 0.1 mm. The strength wet reduction ratio ( DELTA 5) of the fiber is within a range satisfying requirements represented by the following formulae: 0% </= DELTA S1 </= 70%, 20% </= DELTA S2 </= 100% and DELTA S2/ DELTA S1 > 1.10 wherein DELTA S1 represents the strength reduction ratio after two hours' immersion in water at 20 DEG C and DELTA S2 represents the strength reduction ratio after fifty hours' immersion in water at 20 DEG C.
