| Abstract: | The treatment conditions for alkali deweighting of acid-modified multicomponent copolyester fibres have been optimized. The satisfactory silk- like effect is observed under the specific treatment conditions [7.5g/L NaOH, 85°C temperature, 40 min treatment time, 1:40 material-to-liquor ratio, and 1.0g/L promoter]. After alkali deweighting, the special micro-pit structure occurs on the surface of acid-modified fibres which enhances the fibre permeability, adhesion regain, capability of colouring and feel. The X-ray diffraction patterns show that the degree of crystallization of fibre decreases after alkali peeling. |
