Description

Large-diameter polyphenylene sulfide composite monofilament and production method thereof
Technical field
The present invention relates to a kind of large-diameter polyphenylene sulfide composite monofilament and production method thereof.
Background technology
Existing environmental protection filtration fabrics is at the aspect existing defects such as high temperature resistant, corrosion resistance, anti-flammability.Use a kind of resistance to height The corrosion resistant polymer filament of temperature, polyphenylene sulfide filaments.Polyphenylene sulfide can use temperature to be 200 DEG C continuously, acid-alkali-corrosive-resisting Can be good, but polyphenylene sulfide cost of material is high.
Summary of the invention
It is an object of the invention to provide a kind of high temperature resistant, corrosion-resistant, fire resistance that both ensure that polyphenylene sulfide filaments, There are again strength height, the large-diameter polyphenylene sulfide composite monofilament of the measured advantage of springform and the production method thereof of polyester.
The technical solution of the present invention is:
A kind of large-diameter polyphenylene sulfide composite monofilament, is characterized in that: PPS is cortex, PET or PEN is sandwich layer, the quality hundred of PPS Proportion by subtraction be the mass percent of 10-90%, PET or PEN be 90-10%；Filament diameter is 0.08-1.5mm, and intensity is 3.5- 6.5cN/dtex, knot strength is 1.0-4.0cN/dtex, and percentage elongation is 25-45%.
The production method of a kind of large-diameter polyphenylene sulfide composite monofilament, including spinning, liquid cooling, stretching, thermal finalization step Suddenly, it is characterized in that: during spinning, spinning manifold is combined type, i.e. along being longitudinally separated into two heating chambers, controls two kinds of components respectively Melt temperature, melt extruder carries out melt blending and extrudes；PPS spinning temperature is 285-320 DEG C, PET spinning temperature Degree is for 250-295 DEG C, or PEN spinning temperature is 290-325 DEG C；Liquid is cooled to water or polyglycol solution or glycerol is molten Liquid, or the Compound cooling liquid being cooled to be grouped into by the one-tenth of following masses percentage ratio that liquid cooling uses: calcium chloride 30%, carbon Acid hydrogen sodium 15%, Polyethylene Glycol 30%, water 25%；Liquid chilling temperature is 20-80 DEG C, and draft temperature is 85-175 DEG C, thermal finalization temperature Degree is for 95-250 DEG C.
The present invention both ensure that high temperature resistant, corrosion-resistant, the fire resistance of polyphenylene sulfide filaments, the strength having again a polyester is high, The measured advantage of springform, also reduces cost simultaneously, economical and practical.
Below in conjunction with embodiment, the invention will be further described.
Detailed description of the invention
A kind of large-diameter polyphenylene sulfide composite monofilament, PPS is cortex, PET or PEN is sandwich layer, the mass percent of PPS For 10-90%(example 10%, 50%, 90%), the mass percent of PET or PEN is 90-10%(example 10%, 50%, 90%)；Filament diameter For 0.08-1.5mm, intensity is 3.5-6.5cN/dtex, and knot strength is 1.0-4.0cN/dtex, and percentage elongation is 25-45%.
The production method of a kind of large-diameter polyphenylene sulfide composite monofilament, including spinning, liquid cooling, stretching, thermal finalization step Suddenly, during spinning, spinning manifold is combined type, i.e. along being longitudinally separated into two heating chambers, controls the melt temperature of two kinds of components respectively Degree, carries out melt blending in melt extruder and extrudes；PPS spinning temperature is 285-320 DEG C, and PET spinning temperature is 250- 295 DEG C, or PEN spinning temperature is 290-325 DEG C；Liquid is cooled to water or polyglycol solution or glycerin solution, or liquid Cooling use the Compound cooling liquid being cooled to be grouped into by the one-tenth of following masses percentage ratio: calcium chloride 30%, sodium bicarbonate 15%, Polyethylene Glycol 30%, water 25%；Liquid chilling temperature is 20-80 DEG C, and draft temperature is 85-175 DEG C, and heat setting temperature is 95-250 ℃。
When liquid cooling uses described Compound cooling liquid, product various aspects of performance is generally better than under otherwise identical conditions 20%-35% when employing water or polyglycol solution or glycerin solution are coolant.
