Abstract:
A core/sheath temperature-sensitive shape-transformable composite filament comprising a thermoplastic resin (A) and a thermoplastic polymer (B) having a glass transition temperature within the range of from 0.degree.C. to 70.degree.C.;said composite filament being constituted in proportions satisfying the following expressions (1), (2) and (3), and, upon application of an external stress in a temperature region not lower than a temperature about the glass transition temperature of the thermoplastic polymer (B) and lower than its melting point, being transformable to any shapes that conform to that stress, and being capable of becoming fixed to the transformed shape in a temperature region lower than the glass transition temperatureIn the core;(A)/(B)=5/95 to 90/10 (% by weight) (1)In the sheath;(A)/(B)=100/0 to 50/50 (% by weight) (2)Core/sheath=10/90 to 95/5 (% by weight) (3).
