Advantage.
In order to reach antibacterial effect, in the technical solution of the application, the polyester fiber antibiotic layer 5 is using polyester fiber as base
Bottom, added with antibacterial filler.
In mode is preferably carried out, in the polyester fiber antibiotic layer 5, the quality accounting of the antibacterial filler is 10%.
In the prior art, typically additive is added directly into polyester fiber, then melt spinning obtains polyester
, using this scheme, there is the defects of very big in fiber, such as, when the particle diameter for adding additive is relatively located at nanometer range, can produce
Raw serious nanometer agglomeration, this nanometer of agglomeration can cause the uneven dispersion of additive, influence polyester functionalization
Play.In technical solution of the present invention, by adding antibacterial filler in the polyester, and the mass ratio of filler is controlled so that this is poly-
Ester function fiber is provided with the function of antibacterial mite-removing, and generates unexpected technique effect.In addition, the technology of the present invention is led
Domain, in the preparation process of function fiber type, adds pattern, property of filler etc. and plays decisive work to the functionalization of fiber
With.
Antibacterial filler according to the present invention is described below in detail：
The antibacterial filler is TiO2/ sepiolite composite granule, the composite granule are by TiO2It is supported on modified meerschaum
Upper, doping Fe3+What 300 DEG C of calcining 8h of ion and then process were obtained.
Those skilled in the art understand that titanium dioxide is a kind of wide band gap semiconducter, it makees with photo-catalyst
With but since TiO 2 particles particle diameter is smaller, it is difficult to it is effectively fixed, it is simply added in polyester fiber, can be due to
Nanometer reuniting effect, and flock together, it is difficult to antibacterial effect is played, therefore, it is necessary to be supported on carrier, the prior art
In, by titanium dichloride load it has been reported that the carrier for being suitable for titanium dioxide has zeolite, glass fibre, stone in other materials
English, mesoporous silicon oxide etc..
However, do not have also by titanium dichloride load on sepiolite and for the report of polyester fiber, technology of the invention
In scheme, by TiO2Be supported on sepiolite, using sepiolite it is excellent adsorb, the performance such as porous, ion exchange, generate meaning
Technique effect unexpectedly so that the composite granule has good anti-microbial property, and it is dispersed in polyester fiber,
The mechanical property of polyester fiber is ensured.Above-mentioned TiO2In/sepiolite composite granule, composite granule particle diameter is arranged to 6 μm；
TiO2Load capacity is preferably 10~40%, more preferably 20~30%, preferably 24%.
Performance of the particle diameter of filler for filler effect plays an important role, and in technical solution of the present invention, control is compound
The particle diameter of powder so that it disclosure satisfy that the process prepared applied to polyester fiber, and produce good effect.
