Description
Technical field
The present invention relates to fiber, more particularly to a kind of PET/PTT blending and modifyings fiber.
Background technology
PET (poly ethylene terephthalate, polyethylene terephthalate) is nineteen fifty-three by Dupont
Company realizes industrialized linear thermoplastic's polymer earliest, be it is a kind of have higher melting temperature (Tm) and glass transition temperature
(Tg) crystalline high polymer, can keep excellent physical property and mechanical property within the scope of wider temperature, it resistance to
Fatigability, rub resistance are excellent, and resistance to ag(e)ing is excellent, and electrical insulating property is protruded, stable to most of organic solvents and inorganic acid, and
And energy consumption is very low, processability is good, thus is widely used in the fields such as synthetic fibers, film and engineering plastics, but by
Make its crystallization rate slower in PET rigidity, the shortcoming of mould temperature height and molding cycle length makes it in engineering plastics
Application in field is restricted.
PTT be by terephthalic acid (TPA) (the application PTT of PTT should
With PTA) and 1,3- propane diols (PDO) polycondensation form, its molecular structural formula is ((CH2) 3O O=C O=CO)) ptt fiber is comprehensive
The flexibility of nylon, the bulkiness of acrylic fibers, the pollution resistance of terylene, add elasticity inherently, and can normal temperature dyeing etc.
Feature, rolls into one the excellent wearability of various fibers, so that as the currently popular macromolecule of recent development in the world
One of new material.
In the prior art, by obtaining elastic preferably fiber for PET and PTT blendings.But in the prior art
PET and PTT blended fibers under cryogenic, elastic modelling quantity can significantly decline.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide still have preferably elasticity under a kind of low temperature
The PET/PTT blending and modifying fibers of modulus.
To achieve the above object, the invention provides following technical scheme：
A kind of PET/PTT blending and modifyings fiber, including following parts by weight composition：
30 parts of PBT
15 parts of PTT
5 parts of compatilizer
0.5 part of nucleation accelerating agent
20 parts of modified Teflon fiber
The modified Teflon fiber is constituted including following weight parts：

As a further improvement on the present invention, the nucleation accelerating agent is talcum powder.
As a further improvement on the present invention,
Step 1: the mass fraction as described in claim 1 to 5 weighs each component, and by the PET weighed and PBT 110~
Drying time more than 4 hours at a temperature of 130 DEG C, other components are dried more than 2 hours at a temperature of 60~80 DEG C；
Mixed Step 2: the PET after drying process, PTT, compatilizer, nucleation accelerating agent are put into high-speed mixer, in normal temperature
5~15min of lower stirring；
Step 3: the mixed material of step 2 is added in the hopper of double screw extruder, modified Teflon is fine
Tie up and add mouth from the glass in twin-screw stage casing and add, extruded through melt blending, water-cooled, air-dry, pelletizing；
Wherein, the temperature setting of double screw extruder is：One area：200℃；2nd area：220℃；3rd area：220~220 DEG C；4th area：
240℃；5th area：250℃；6th area：250℃；7th area：250℃；8th area：260℃；Head temperature：250℃；Screw speed is controlled
In 200~400r/min.
In the present invention, it is PET and PTT blending first, in Blending Processes, passes through compatilizer and nucleation accelerating agent
Addition enables to the PET and PTT mixing can be fully compatible and nucleation.As the key of the present invention, for polytetrafluoroethylene (PTFE)
It is modified, is by N- (BETA- aminoethyls)-GAMA- aminopropyl trimethoxysilanes, double (two first in modifying process
Methyl ammonia) dimethylsilane, trifluoro propyl trichlorosilane, the addition of (bromomethyl) trimethyl silane, can be for polytetrafluoroethyl-ne
Alkene is modified so that the material that modified Teflon is prepared into PET and PTT blendings carries out compound tense, can be had more preferable
Combined strength bination, while by the addition of compound ether, overall composite effect can be further improved, while collaboration can be played
Effect so that fiber still has preferably elasticity at low temperature.
