MODIFIED POLYESTER POLYMER AND MANUFACTURING METHOD THEREOF, AND POLYESTER FIBER FROM SAID POLYESTER AND MANUFACTURING METHOD THEREOF

摘要

the invention of the formula (1) representing the metal sulfonate (sulfonate) salt of 0.3 to 5 parts by weight % and containing a polyoxyalkylene ether compound represented by the formula (2) 0.5 to 10% by weight of modified polyethylene terephthalate polymer and a method for containing, and methods of manufacturing polre ester fiber and the fiber to be produced from the polymer being . The alone or when using the fiber manufacturing a composite organization obsessed with knitting and other fiber processing quality loss be fine slits or micro-craters are formed in the fiber axis direction hygroscopic, antistatic, exhibit nongyeom sex and also silk and wool and will exhibit a similar texture of natural fibers. ; (in which R is R ¹ represents an alkyl group of a carbon number of 10 ~ 500 M is an alkali metal of Na, K, an alkaline metal selected from Li.) ; (The where R ² , R ⁴ is hydrogen or methyl, ethyl or the like which is selected from a phenyl group, or represents a different functional group R ³ is an ethylene, 1,2 propylene or 1,3 propylene, 1,4-butylene group selected from an alkylene group, and n is an integer of 15 ~ 200.)
