Description
Technical field
The present invention relates to the modification fields of polyester fiber, and in particular to a kind of modified polyester fiber and preparation method.
Background technique
Polyester fiber is commonly called as " terylene ", is that the polyester as made of organic dibasic acid and organic diol polycondensation is obtained through spinning
The synthetic fibers arrived, abbreviation PET fiber.Its four wrinkle resistance of biggest advantage and conformality are fine, intensity with higher and bullet
Property recovery capability, therefore use weaving is upper a large amount of.
As people's living standard is higher and higher, the requirement to dress is also higher and higher, and not only clothing color is various, and
Require some special performances, such as antistatic property, ultraviolet-resistent property etc..Antistatic property is usually to be added in textile fabric
Some antistatic agents or conductive agent, or in final finishing with some hydrophilic finishing agents, ultraviolet-resistent property is usually to weave
Some anti ultraviolet agents are added in fiber or in final finishing with some finishing agents with uvioresistant function.It wherein will be antistatic
The modifying agent such as agent, conductive agent or anti ultraviolet agent are added in fibre spinning molding, and modifying agent disperses in the fibre, and washability is good,
It is able to maintain the more long functionality time.
Cage modle polysilsesquioxane, abbreviation POSS have general structure (RSiO1.5)n, it is the silicon alternately connected by Si-O
The inorganic kernel of oxygen skeleton composition, the group R that Si atom is connected on its apex angle are reactivity or inertia group.The three of POSS
Size is tieed up between 1.3nm, wherein the distance between Si atom is 0.5nm, and the distance between R group is 1.5nm, belongs to nanometer
Compound.POSS through being added in polymer frequently as additive so that modified polymer heat-resistant, mechanical property plus
Work performance, anti-flammability can be improved effectively.
Graphene (Graphene) be one kind by carbon atom with sp2Hybridized orbit forms the two dimension that hexangle type is in honeycomb lattice
Carbon nanomaterial.Since 2004 are found, graphene have excellent optics, electricity, mechanical characteristic, materialogy,
Micro-nano technology, the energy, biomedicine and drug delivery etc. are with important application prospects, it is considered to be a kind of future revolution
The material of property.Graphene is added to the thermal conductivity, electric conductivity, mechanical strength etc. that polymer can be improved in polymer.
Application of the graphene in weaving is mainly the surface by being added in polymer or being adsorbed on fiber, is formed
Modified fibre have the function of conductive, thermally conductive etc..The Chinese invention granted patent of publication No. CN103966844B discloses one kind
The preparation method of graphene conductive composite fibre, by fiber surface with KH-560 it is silane coupler modified after, be immersed in graphene
It is handled in dispersion, obtains graphene conductive composite fibre, there is preferable electric conductivity.
Finishing agent containing POSS or graphene is applied to the final finishing of fabric, and POSS or graphene pass through chemical graft or object
Reason is adsorbed onto the surface of fabric.But this method has the disadvantage that the POSS for being fabric surface or graphene are being washed, used
It can gradually decrease in the process, cause effect more and more weaker.Another kind into fibre-forming polymer, obtains POSS or graphene dispersion
Functional fiber can have longer action time.
In view of the performance of POSS and graphene, it is to play simultaneously that POSS and graphene are added to purpose in fiber together
The function of POSS and graphene, but both materials, which are added separately in fiber, only can respectively play a role, or even can be mutual
Mutually hinder.And dispersion of the graphene in fibre-forming polymer an important factor for being also an influence modified effect, if dispersion
It is bad, it will lead to some performances decline of fiber instead.
Sulfydryl-alkene clicking chemistry reaction is a kind of " green " chemical reaction, is had without removing water deoxygenation, reaction condition temperature
With the advantages that reaction time is short, reaction conversion ratio is high, reaction product is with high purity, in hydrogel, film, lithographic printing and biology
Material Field has a wide range of applications.
Summary of the invention
(1) the technical issues of solving used
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of modified polyester fibers, have and preferably lead
Electrical property, thermal conductivity, mechanical strength and flame retardant property, and graphene/cage modle polysilsesquioxane composite material additive amount compared with
(mass fraction is more than 5%, or even close to 10%) all with preferable mechanical property greatly.
It is another object of the present invention to provide a kind of preparation methods of modified polyester fiber.
(2) technical solution
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that,
A kind of modified polyester fiber is made of following raw material by weight percentage, 1~50% polyester/graphite alkene/POSS
Particle and 50~99% polyester.
Preferably, by weight percentage, it is made of following raw material, 5~20% polyester/graphite alkene/POSS and 80~95%
Polyester.
It is furthermore preferred that the preparation method of the polyester/graphite alkene/POSS particle includes the following steps,
S1: according to parts by weight, 1~10 part of graphene oxide is added to 20~30 points of ultrasound in 1000 parts of dehydrated alcohols
Clock is added and contains vinyl silicane coupling agent, and the micro- reflux of system is warming up under stirring, reacts 1~2 hour, and filtering removes filtrate,
It filters out solid washes of absolute alcohol 5 times, dries in vacuum drying oven to constant weight, obtain vinyl modified graphene oxide；
S2: according to parts by weight, the vinyl modified graphene oxide in 5~20 parts of step S1 is added to 1000 parts of second
Eight (3- mercaptopropyi) cage modle polysilsesquioxanes (HS-POSS) and HS-POSS weight are added in ultrasound 20~30 minutes in acetoacetic ester
