Description
Affiliated technical field
The invention belongs to features cloth production field.
Background technology
High-performance polyphenylene sulfide has the heat endurance under excellent chemical proofing and the high temperature, and has fire-retardant, insulation, radiation hardness and good mechanical performance.For enlarging the scope of application of this material, the researchers of various countries make it the new method that fibration is used in searching always.
PPS fiber chemical-resistant stability is good, and it still can keep its original performance under extremely abominable condition, have outstanding chemical stability, is only second to polytetrafluoroethylene fibre.At high temperature, be placed in the different inorganic reagents and can keep original tensile strength after the week.It also has the performance of good organic solvent-resistant, except 93 ℃ toluene are slightly influential to its intensity, in the organic solvents such as carbon tetrachloride, chloroform, even its intensity still can not change place a week under boiling point after, temperature is that 93 ℃ formic acid, acetic acid does not affect its intensity yet.The nonwoven fabric filter fabric of being made by polyphenylene sulfide fibre has good corrosion resistance in 93 ℃ 50% sulfuric acid, strength retention does not make significant difference.Placed for two weeks in 93 ℃, 10% sodium hydroxide solution after, its intensity does not significantly change yet.
PPS fiber good heat stability, it has outstanding heat-resisting quantity, and fusing point reaches 285 ℃, is higher than other melt-spun fibres of present suitability for industrialized production, so dimensionally stable.Its limited oxygen index can reach 35%-45%, can not burn under normal atmospheric conditions.The heat resistance of polyphenylene sulfide fibre also shows: its strength retention in the time of 200 ℃ is about 40% when being 60%, 250 ℃.Below 250 ℃ the time, its extension at break remains unchanged substantially.If its multifilament is placed 200 ℃ high temperature furnace, fracture strength remains unchanged substantially after 54 days, and extension at break is down to 50% of initial collapse elongation; Under 260 ℃ after 48 hours, still can keep 60% of fiber initial strength, extension at break is down to 50% of initial collapse elongation.Go out outside this, the PPS fiber has good textile process performance, can be processed into the fibre of all size, various shapes.
In Chinese patent application number NO:CN1767882, narrated the filtering material that uses polyphenylene sulfide and polytetrafluoroethylene fibre to make, although good aspect the dust catching effect, it is to adopt the at present manufacturing technique of all felt cloths, aspect technological process without any the place of innovation.
Introduced a kind of manufacture method of polyphenylene sulfide fibre dust removal felt cloth in Chinese patent number NO:200610022214.4, it also is to adopt the manufacturing technique of traditional felt cloth to make.Also adding simultaneously some aramid fibers or polytetrafluoroethylene fibre is raw material, improves the chemical-resistance of felt cloth with this.
The objective of the invention is to study a kind of high-performance polyphenylene sulfide fibre dust removal felt cloth production technology, improve the permeability of fiber by the choose reasonable process route, the making that then makes the fiber hair felt-cloth in later stage obtain better performance indications is used for the professional filtrate of thermal power generation, incinerator etc.
