FIELD: textile, paper.
SUBSTANCE: to form a double-component fibre with the speed of not higher than 1300 m/min, polyethylene terephthalate is used as a fibre-forming component, and a thermoadhesive component of resin - a crystalline thermoplastic resin with melting temperature that is at least 20°C lower than the melting temperature of the fibre-forming component. A non-drawn thread of the double-component fibre is drawn in cold condition 1.05-1.3 times, relaxed and thermally shrunk at the temperature that is 10°C higher that vitrification temperatures of both components. Fibre has relative elongation at rupture 130-600%, rupture strength at 100% tension - from 0.3 to 1.0 sN/dtex and shrinkage after treatment with dry heat at 120°C by less than - 1.0.
EFFECT: fibre has higher bulking power, and material made from it - good drape effect.
