Abstract

PURPOSE: Void-free fiber made from modified polyester containing a sulfonic acid compound is treated with an aqueous alkali solution to form specific fine voids in the fiber, thus giving fiber showing a deep-tone color when dyed.
CONSTITUTION: A modified polyester containing preferably 2W16mol% of a sulfonic acid compound of the formula (Z is aromatic or aliphatic; M is metal or H; R1, R2 are ester-forming functional group; n is 0, 1) is mixed with unmodified polyester, preferably by 0.1W100pts.wt. per 100 pts. of the unmodified polymer and the composition is melt spun to form void-free fiber. Then, the resultant fiber is treated with an alkali aqueous solution to remove 2W50wt% from the fiber, thus forming the objective fiber in which fine voids have 0.1W0.3μ diameter at the maximum frequency distribution in the peripheral area with more than 0.5μ thickness in the cross section and extend in the fiber axis direction and at least a part of them are opened.
