Abstract

PURPOSE: Polyester fiber containing porous silicate is treated with an alkali solution to reduce its weight, thus producing the titled fiber with improved dyeability, which is used as fancy yarns, because the dyed fabrics therefrom give deep color tone and clear light and shade.
CONSTITUTION: A silicate such as anhydrous zeolite with fine voids is added to chips of polyester such as polyethylene terephthalate and they are uniformly mixed by means of a melt stirrer, then made into fiber with an extruder-type melt spinning machine. Then, the resultant undrawn fiber is drawn to give polyester fiber containing porous silicate. The polyester fiber is boiled in an aqueous solution of sodium hydroxide to reduce the weight, thus giving the objective fiber. The particles size of the porous silicate is less than 3μ and the content in the polyester fiber is preferably 0.1W5wt%.
