Abstract
The invention provides a functional agricultural cloth prepared from 96-98.3% of polypropylene, 1-2.5% of an aging resistor, and 0.7-1.5% of a color master batch. The manufacture method comprises the steps that 96-98.3% of polypropylene, 1-2.5% of an aging resistor, and 0.7-1.5% of a TL-F3009 or TL-F2328 color master batch are taken and mixed uniformly and then the mixture enters a screw melted extrusion machine; when the mixed raw materials are heated to the temperature of 210-235 DEG C suitable for spinning, the melt thereof is extruded by a screw and jetted out uniformly via groups of rectangular spinneret plates, wherein the number of holes of each spinneret plate is not greater than 500. The rotation speed of a metering pump is 35-40g/m<2>, and 25-29rpm is used for the agricultural cloth. The jetted filaments are cooled by air; the side blowing pressure of a compressor is 10-25Par. A spinning drafting system and a web former form an angle of 18-20 degrees. The functional agricultural cloth is good in anti-ageing performance, good in heat preservation and breathability and long in service lifetime (outdoor service lifetime being 2-3 years) and is in favor of crop growth and yield increase. An anti-counterfeiting mark is integrated to the functional agricultural cloth, so that the anti-counterfeiting effect is good.
Description
Technical field
The present invention relates to a kind of agricultural fabric, specifically relate to hole, a kind of spinneret hole count≤500, the fine number of monofilamentAt 5.5dtex---between 6dtex, and the one-body molded functional fabric for agriculture that has mark and preparation method thereof.
Background technology
In order to reach the desired humiture of crops, promote crop growth and early sowing, high yield, stable yields, veryMany peasants use polypropylene filament nonwoven in crop cultivating procedure. The spray of one of this non-woven fabric manufacturing equipmentThe hole, spinneret orifice >=750 of filament plate, filament number is at 2.5dex---between 4.5dex. Spinning drawing system withBetween lapper, vertically there is no angle. Owing to there is no age resister, only 3-6 month service life, heat-insulating propertyNot high, permeability is poor, and service life is short, can not reach the object of expection promotion crop growth and high yield.
Summary of the invention
Object of the present invention, is for the problems referred to above, provides that a kind of heat-insulating property is high, good permeability, uses the longevityLife is long, is conducive to crops and generates and improve the functional fabric for agriculture of crop yield.
Another object of the present invention, is to provide a kind of will mark and functional fabric for agriculture integral formation method.
For achieving the above object, the present invention adopts following technical scheme:
Functional fabric for agriculture is by polypropylene 96-98.3%, age resister 1-2.5%, Masterbatch 0.7-1.5% is mixed with. Above-mentioned percentage is weight percentage.
Above-mentioned age resister can be preferably: TL-F9002.
The preparation method of functional fabric for agriculture, comprises the steps:
Get polypropylene 96-98.3%, age resister 1-2.5%, TL-F3009 or TL-F2328 Masterbatch0.7-1.5% enters in screw rod melt extruded machine after mixing, and mixed material is heated to and is suitable for spinningTemperature 210-235 DEG C time, its melt, by screw extruding, is evenly sprayed spinneret by every group of rectangle spinneretHole, hole count≤500. Measuring pump rotating speed is at 35-40g/m2When agricultural fabric, be 25-29rpm, the long filament of ejection is wantedCarry out air-cooledly, 10-25Par is pressed in compressor side blowing, between spinning drawing system and lapper, forms 18-20Degree angle.
Compressed air sprays from the stretching tube of air drawing device, long filament stretched cooling, and drawing-off blastFor 40-45par, long filament speed enters pendulum wire device under air drawing effect, and frequency is 220-300 beat/min, makesIt is separated from each other under effect of impact, inhales to becoming lace curtaining, is condensed into net, and solidifying lace curtaining constantly turns round,, will formFibre web input hot bundle machine, its technical essential is that the agricultural fabric mark of making is in advance placed on fibre web and is establishedAllocation, and enter together hot-rolling mill in company with the fibre web forming, hot rolling synthesizes an overall structure. Hot-rolling mill linePressure is 25-50mpar, and flower roll temperature is 145-155 DEG C, and hot rolling speed is at 35-40g/m2When agricultural fabricFor 36-43.5m/min.
The above-mentioned words identification that is designated, also can be pattern identification or word adds pattern identification.
This agricultural fabric finished product forms 49≤cm of tying point2. Again through coiling, debatching, cut, pack,Listing.
Functional fabric for agriculture of the present invention, ageing resistace is high, insulation and good permeability, long service life (chamberBe 2-3 outer service life), be conducive to crop growth and improve output. In addition, anti-counterfeiting mark and functionProperty agricultural fabric is integrated, and antifalse effect is good.
