Abstract
The invention provides a polyphenylene sulfide fiber with excellent light resistance. The light resistance is improved by adding an ultraviolet absorber into polyphenylene sulfide (PPS) resin materials, and the addition amount of the ultraviolet absorber is 0.5% to 10% by weight. The invention well solves the problem in the prior art that the PPS fiber has poor light resistance. Therefore, the PPS fiber has broad application prospects in clothing industry.
Description
Technical field
The present invention relates to a kind of polyphenylene sulfide fibre.
Background technology
Polyphenylene sulfide fibre (PPS fiber) is a kind of functional special fiber.Generally adopt conventional melt spinning method, at high temperature carry out after-drawing then, curl and cut-out makes by polyphenylene sulfide (PPS resin).The PPS fiber has excellent heat endurance and anti-flammability, oxygen index value 34～35, and strength retention is 60% in the time of 200 ℃, the extension at break no change; Chemical resistance is only second to polytetrafluoroethylene fibre; Textile processibility ability is preferably arranged.The PPS fiber is mainly used in filtration, the dry zone of paper industry and the cable encapsulate layer and the fire-proof fabric etc. of preparation high-temperature flue gas and special thermal medium.But,, be difficult to be applied on the clothes purposes though have good heat-insulating property because the fast light property of shining of PPS fiber is poor.
In PPS fiber related patent U.S. Patent No. in the past, the light fastness that relates to the PPS fiber is arranged also.For example disclose a kind of ultraviolet radiation resisting polyphenylene sulfide and preparation method thereof among the patent CN200710046845.4, BTA has been reduced the PPS fiber optic as main light stabilizer change according to front and back colourity and the mechanical property variation.But the molecular weight of BTA is too small, and sublimation temperature is 100 degree only, the granulation process of light stabilizer and with PPS resin alloy process in loss very big, role is very little.
Disclose a kind of polyphenylene sulfide member among the patent CN200510128932.5 simultaneously, reached sunproof effect through adding light absorber, wherein light absorber also is the medicine that contains the BTA structure, and role is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of polyphenylene sulfide fibre with excellent in resistance optical property.
The heat-insulating property of PPS fiber is superior, but light fastness is poor; Invention prepares and has the light fastness polyphenylene sulfide fibre through adding compound, and it also is expanded in the clothes purposes.
Technical solution of the present invention: a kind of polyphenylene sulfide fibre; Wherein mainly contain 90～99.5% polyphenylene sulfide and the compound of 0.5～10wt%; Said compound is compd A and/or compd B; The structural formula of compd A is suc as formula shown in 1, and the general structure of compd B is suc as formula shown in 2
In the formula 2, R
1Be alkyl, R
2Be hydrogen atom or methyl, n=1～4.
The production method of polyphenylene sulfide fibre of the present invention; Comprise the steps: in 90～99.5% polyphenylene sulfide, to add the compound of 0.5～10wt%; Said compound is compd A and/or compd B, and the structural formula of compd A is suc as formula shown in 1, and the general structure of compd B is suc as formula shown in 2; In the formula 2, R
1Be alkyl, R
2Be hydrogen atom or methyl, n=1～4; Through screw extruder blend granulation, dry back spinning, coiling, hot-stretch make polyphenylene sulfide fibre.
Compd A is two BTA structures, and its fusing point does not have particulars record boiling point about 200 degree, and the laboratory is heated to 300 degree and does not decompose; The fusing point of compd B also is not less than 180 degree, under the processing temperature of PPS fiber, does not still decompose, and does not distil, and has good additive effect.Thereby the polyphenylene sulfide fibre that obtains has good spinnability and color fastness to light.It is more than 3 grades that fiber process becomes the light resistance behind the fabric.
