FIELD: chemistry.
SUBSTANCE: multicomponent fibre contains at least two elongated fibre bodies, where the first fibre body consists of a first material containing a phase change material, and the second fibre body consists of a second material and surrounds the first fibre body. The phase change material is in an initial form. The first material contains a viscosity modifier selected from polyolefins having density in the range of 890-970 kg/m3, determined at room temperature according to ISO 1183-2, and melt flow rate in the range of 0.1-60 g/10 min, determined at 190°C with a load of 21.6 kg according to ISO 1133.
EFFECT: high latent heat and strength of the fibre.
