A preparation process of flame-retardant polyester fibers, comprising the steps of: impregnating polyester fibers with a flame retardancy giving liquid containing a phosphorus compound as a flame-retarder represented by the formula (I):
wherein Ar represents a phenyl or naphthyl group which may be substituted by C1-4 alkyl groups, and n represents an integer 1 to 3; thermally treating the polyester fibers under normal or increased pressure after or at the same time as the impregnation treatment; and thereby giving flame retardancy to the polyester fibers.
一种阻燃聚酯纤维的制备工艺,包括以下步骤:用含有磷化合物的阻燃剂液体浸渍聚酯纤维,该阻燃剂由式(I)表示:
其中 Ar 代表可被 C1-4 烷基取代的苯基或萘基,n 代表 1 至 3 的整数;在浸渍处理之后或同时,在常压或增压下对聚酯纤维进行热处理;从而使聚酯纤维具有阻燃性。
