Description
Technical field
The present invention relates to a kind of light resistance polyphenylene sulfide fibre.
Background technology
Polyphenylene sulfide fibre (PPS fiber) is a kind of functional special fiber.Generally adopt conventional melt spinning method by polyphenylene sulfide (PPS resin), then at high temperature carry out after-drawing, curling and cut-out is rear obtained.PPS fiber has excellent heat endurance and anti-flammability, oxygen index value 34 ~ 35, and when 200 DEG C, strength retention is 60%, and extension at break is unchanged; Chemical resistance is only second to polytetrafluoroethylene fibre; There is good textile process performance.Current PPS fiber mainly for the preparation of the filtration of high-temperature flue gas and special thermal medium, the dry zone of paper industry and cable encapsulate layer and fire-proof fabric etc.
Although polyphenylene sulfide fibre has good heat-insulating property, resistance to actinic difference, so be difficult to be applied on apparel applications.
In the polyphenylene sulfide fibre Patents in the past, also there is the light fastness relating to polyphenylene sulfide fibre.Such as, disclose a kind of ultraviolet radiation resisting polyphenylene sulfide and preparation method thereof in patent CN200710046845.4, benzotriazole is reduced PPS fiber optic according to the change of front and back colourity and mechanical property change as main light stabilizer.But the molecular weight of benzotriazole is too small, sublimation temperature only 100 degree, light stabilizer granulation process and with PPS resin alloy process in lose very large, role is very little.
In addition, proposing in PPS, add benzotriazole or nano titanium oxide or both mixtures in the research of document 1001-0041 (2008) 03-0008-04 blended remodeling polyphenylene sulfide fibre photostability can make PPS light resistance improve, bibliography data find to improve DeGrain, in order to verification the verifying results, author finds to improve DeGrain according to after literature content test, under JIS-L0842 benchmark, light resistance is only 1 grade, can not be used as clothing fabric at all.
In sum, the heat-insulating property of PPS fiber is superior, but light fastness is poor; In the urgent need to one invention, the PPS fiber with light fastness can be prepared, PPS fiber is also expanded at apparel applications.
