Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
nullThe present invention introduces a kind of method of continuous way melt spraying non-woven fabrics，Including step in detail below，First PBT raw material is dried process，By feeder, PBT raw material is delivered to extruder after dried，PBT granule heating is melted by extruder，Then the PBT after heating and melting is delivered to the spinneret spray webbing at spinneret die place，And under gas drawing, form superfine fibre，Described gas is sprayed by spinneret 2 both sides，Air compressor 3 first compresses air and the air of compression is reached air heater 4 heats，The equidirectional ejection of fiber that the gas pipeline that air after compression heating is connected to spinneret 2 sprays with spinneret place，Described high temperature air can be 400 DEG C、410℃、420 DEG C etc.，Described air pressure can be 0.08MPa、0.12MPa、0.22MPa、0.25MPa etc.，Described superfine fibre is sprayed on the reception device 5 laterally longitudinally moved back and forth with low speed at a high speed and is cooled into non-woven fabrics through air，Described high speed lateral velocity be 0.1 second to 4 seconds one back and forth，Described low speed longitudinal direction rotating speed is 0.1 to 10 hertz，Non-woven fabrics is delivered to rolling on drum receiver 6 again，Described reception device is a lateral section is three structures of triangle，The junction of three is provided with runner，After the one side full PBT of upper sprinkling forms non-woven fabrics，Receive device three face to rotate，Convert another blank face to just to spinneret，The non-woven fabrics formed is sent to roller coiling gradually，The speed of described reception device is by controller control，Parameters first can be set in the controller before operational outfit，It is made to carry out Automated condtrol，PBT Chinese is polybutylene terephthalate (PBT)，It is called for short saturated polyester，It it is high crystalline thermoplastic plastic，Due to good fluidity，Crystallization rate is fast，It is suitable for producing superfine fibre class non-woven fabrics，And PBT material to have coefficient of friction little and have the feature of self-lubricity，Therefore the PBT non-woven fabrics blood class Filters manufactured is used，And this method is simple to operate，Use single raw material，Mix without any additive or with other raw materials，Therefore stability of characteristics in high temperature production，Easily controllable，The situation that raw material and other additives react will not be there is，And this method uses feeder to carry out continuous charging，Receive device and drum receiver receives non-woven fabrics jointly，Mechanization degree is high，Time saving and energy saving and can pass through to regulate the speed of upper cotton conveyer belt、The thickness of smooth forming machine and the speed of drum receiver regulate the specification of non-woven fabrics.
Additionally, when charging, first charging aperture is carried out cooling process, temperature controls below 100 DEG C, and this can be avoided PBT when heating, and temperature too high causing melts too fast formation bulk and cause equipment to block.
Further, spinneret has plurality of specifications, described spinneret adopt round aperture, aperture size is 0.2-0.4mm, this can so that in blood filtration normal cell energy not damaged pass through so that this kind of non-woven fabrics can give play to very strong effect at medical domain.
Additionally, PBT after melting sprays through the spinneret at meltblown beam place first passes through distribution plate, described distribution plate is the round panel having many holes so that the PBT liquid after melted flows through flow speed stability after circular hole, can evenly spray from spinneret.
In addition, spinneret adds heat block, the solution before spinneret is provided with heat block so that PBT continues to heat to keep temperature after melted and before spinneret spray webbing, prevent the PBT after melting from solidifying in advance because temperature reduces, thus affecting the quality of the non-woven fabrics made.
In addition, before forming gas, gas need to be dried process, discharge steam, prevent steam to be mixed in high-speed high-temperature gas and spray on the reception device with superfine fibre, superfine fibre is made to form blister in forming process, affect ultraviolet absorptivity, affect the quality of the non-woven fabrics of molding, described ultraviolet absorptivity is non-woven fabrics in detected, detection liquid is by after non-woven fabrics, with a numerical value of the liquid ultraviolet absorptivity that ultraviolet spectrophotometer is measured, the numerical value measured of the non-woven fabrics that the method produces and the difference of blank solution are less than 0.300, meet national standard.
The nonwoven made by continuous way melt-blowing equipment is furnished with following characteristics, and non-woven fabrics is formed by monolayer PBT fine resin fiber multiple-layer stacked, and the fiber string diameter of described non-woven fabrics is at 1-25 μm, and the aperture of non-woven fabrics is at 1-80 μm, and the grammes per square metre of non-woven fabrics is at 50-180g/m2, the thickness of non-woven fabrics is at 0.1-4mm, and non-woven fabrics differential water pressures is at 12-60H2Ocm, this kind of non-woven fabrics owing to using PBT material, made of soft, the infringement of cell is little, it is adaptable to medical domain, and because low price, can be mass-produced.
Particular embodiments described above; the purpose of the present invention, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
