The high strength of acupuncture compound is without a manufacture method for electrostatic anti-slip automobile seat non-woven fabrics, and the method comprises the steps:
The manufacture of the chopped fiber needle-punched nonwoven layer of A:PET 1 and the chopped fiber needle-punched nonwoven layer 23 of PET: will be that the L-PET of 30% and the PET of 70% are put in opener and carried out shredding according to mass percent; Then the composite fibre after shredding process is put into blending box to mix; Then the fiber mixed is put in carding machine to carry out dredging and is put down by mixing; After dredging reef knot bundle, composite fibre is sent in lapping machine and is paved into multi-layered web; Composite fibre is sent in needing machine after lapping terminates and carries out acupuncture processing process; The product finally acupuncture terminated undertaken batching by lapper can obtain the chopped fiber needle-punched nonwoven layer 23 of the chopped fiber needle-punched nonwoven layer of PET one 1, PET method for making with the chopped fiber needle-punched nonwoven layer 1 of PET;
The manufacture of the long fine spun-bonded non-woven fabrics layer 2 of B:PET: then High Viscosity PET particle is put in screw extruder after crystallization, drying and extrudes under the state of high-temperature fusion, then filtered by filter, then enter into manifold and carry out wire drawing, by carrying out lapping in lapper after wire drawing terminates, then in hot-rolling mill, carry out pre-hot rolling, carry out batching finally by lapper and can obtain the long fine spun-bonded non-woven fabrics layer 2 of PET;
C: long for PET fine spun-bonded non-woven fabrics layer 2 is stung laminating with the chopped fiber needle-punched nonwoven layer of PET 1 by hangnail eedle, form the laminating layer of 1+2, and then chopped fiber needle-punched for PET nonwoven layer 23 is placed on above the long fine spun-bonded non-woven fabrics layer 2 of PET, laminating by hangnail eedle thorn, form the laminating layer of 1+2+3, needling density controls at 90 pins/CM
2, depth of needling controls at 12MM, and L-PET is melted by blancher heating by laminating good product again, and heating-up temperature is 180 DEG C, makes it play the effect of glue, by fixing for various fiber more firm, and last rolling;
D: producing of flame-retardant layer 4: prepare burden by formula, the material prepared adds mixing and stirring in mixer, mixing temperature is 110 DEG C, incorporation time is 10 minutes, after mixing, to transfer in cooling and stirring machine at 50 DEG C stirring at low speed 10 minutes, finally enter that extruder plastifies at 170 DEG C, pelletizing, last cross cutting, rolling;
E: producing of waterproof and oilproof anti-static compound layer 5: prepare burden by formula, the material prepared adds mixing and stirring in mixer, mixing temperature is 120 DEG C, incorporation time is 10 minutes, after mixing, to transfer in cooling and stirring machine at 40 DEG C stirring at low speed 10 minutes, finally enter that extruder plastifies at 180 DEG C, pelletizing, last cross cutting, rolling;
F: the product obtained in step D is effectively combined with each other by the product back side obtained in blanching compounding machine and step C, wherein combined temp is 180 DEG C;
G: the product obtained in step e is effectively combined with each other by the product back side obtained in blanching compounding machine and step F, wherein combined temp is 180 DEG C;
H: the product obtained step G, is heated by forming machine, compression molding, wherein temperature 220 DEG C, 100 seconds dwell times, namely obtains required non-woven fabrics finally by the front embossed of embossing machine to product.
