Abstract

The invention relates to fluorinated polyester polyester pre-oriented yarn (POY) fibers and a preparation method thereof. The preparation method comprises fluorinated polyester melt preparation and fluorinated polyester POY fiber preparation, and concretely comprises the following steps of 1, adding an inhibitor into fluorine-containing terephthalic acid and glycol as raw materials, and preparing the mixture into fluorinated polyester melt, and 2, carrying out direct extrusion on the fluorinated polyester melt or carrying out slicing and screw melt extrusion on the slices, and carrying cooling, oil coating and winding to obtain the fluorinated polyester POY fibers. The novel fluorinated polyester POY fibers have monofilament fineness of 0.5-3.0dtex, fiber breaking strength of 1.6-2.5cN / dtex and breaking elongation of 110-150%. Through use of fluorine atoms, super-hydrophobic, hydrophobic, oleophobic and antifouling performances of the polyester POY fibers are improved. The fluorinated polyester POY fibers have a wide application prospect in manufacture of waterproof and antifouling working clothes and special industry working clothes.

Description

technical field

[0001] The invention relates to a fluoropolyester POY fiber and a preparation method thereof, in particular to a fluoropolyester POY fiber in which hydrogen on a benzene ring is replaced by fluorine and a preparation method thereof. Background technique

[0002] Polyester (PET) is one of the most widely used synthetic polymers by humans. PET was synthesized as early as the 1940s, and it was found to have excellent properties, and it is widely used in textiles, packaging, and medical treatment. Sanitation, automobiles, electronic appliances, safety protection, environmental protection and other fields. Pre-oriented yarn POY refers to the raw yarn that has not been stretched but can be directly stretched and deformed. It is required that the POY yarn can be stored for a long time and has certain structural stability and processability. During the processing of POY yarn, there are generally no problems such as difficulty in spinning, finished silk wool, low str...
