Abstract
The invention discloses a method for manufacturing a mixed staple fiber needle-punched high-strength geotextile, and relates to the technical field of needle-punched geotextile. The conventional needle-punched geotextile has the defects of quality fluctuation and low strength. The invention has the purposes that: 1, the purpose of reinforcing the geotextile is fulfilled by a method of changing a staple fiber formula; 2, the purpose of reducing staple fiber damage rate is fulfilled by a method of changing the needle-punched shape of a main punching machine; 3, the purpose of enhancing the strength of the geotextile is fulfilled by re-melting the damaged staple fiber interlacing points together through pressure melting points arranged in uniform point lattices and formed by non-barb punching needles; and 4, the purpose of greatly improving the properties of the geotextile is fulfilled by changing the state of partial staple fibers through heating. The mixed staple fiber needle-punched high-strength geotextile obtained by the manufacturing method has wide market prospect.
Description
Technical field
The present invention relates to acupuncture geotextiles manufacturing technology field.
Background technology
The present invention mixes chopped fiber needle-punched high-strength geotextiles manufacture method.There is following defective in existing acupuncture geotextiles manufacture method: one, the composition of raw materials characteristic is single; Two, the pricker wearing and tearing cause quality fluctuation; Three, fiber is stung the disconnected geotextiles intensity decreases that causes.
Summary of the invention
The objective of the invention is: one,, reach the purpose of reinforcement by changing the method for short fiber prescription; Two, by changing the method for main-needling machine pricker shape, reach the purpose that reduces the short fiber damage ratio; Three, the pressure fusing point that forms of the no hangnail pricker that is provided with by even dot matrix is put again blow together with the short fiber interleave that has been damaged; Reach the purpose that strengthens geotextiles intensity.Four, change part short fiber state by heating, reach the purpose of significantly improving the geotextiles characteristic.
Technical scheme of the present invention is such: one, change the prescription of raw material, in the fiber number that changes fiber, length; Change the material formula of fiber.Two, after needling density reaches the typing requirement, add a main-needling machine that changes the pricker shape; Pricker adopts the even dot matrix method to set up of no hangnail.Three, adopt the molten method of no hangnail pricker moment pressure, the fiber that is damaged that hook is connected together is fixed together again; Effectively improve the intensity of geotextiles.
Four, heating is melted part short fiber wherein after finishing the acupuncture typing, can significantly improve the geotextiles characteristic after the cooling.The present invention of manufacture method acquisition has as mentioned above been arranged, and the high-strength geotextiles market prospects of blended fiber acupuncture are unlimited.

Concrete enforcement
Design philosophy key of the present invention is: the chopped fiber needle-punched high-strength geotextiles manufacture method of described mixing is by, high-melting-point short fiber (1), low melting point short fiber (2), band broach pin hole (3), no hangnail brilliance post pricker pin hole (4) composition.
Design philosophy key of the present invention is: described high-melting-point short fiber (1), mixed and formed by bidimensional, three-dimensional hollow short fiber; In the total amount proportioning, account for 55～100%; Wherein the bidimensional short fiber accounts for 55～100%; Fusing point is 130～300 ℃; Three-dimensional hollow short fiber accounts for 55～100%; Fusing point is 130～300 ℃.
Design philosophy key of the present invention is: described three-dimensional hollow short fiber, under the situation of equal fiber number; Shared cross section, space is greater than solid bidimensional short fiber, so the probability that is disconnected by thorn is just low; The three-dimensional high bulkiness of tool makes more apparent texture in the geotextiles contrast of equal grammes per square metre; Geotextiles has been strengthened prevent the regulating quantity that force majeure destroys.
Design philosophy key of the present invention is: described low melting point short fiber (2) accounts for 0～45% in the total amount proportioning; Fusing point is 110～230 ℃.
Design philosophy key of the present invention is: described band broach pin hole (3), when ensureing gas permeability, leaking fine sand also for preventing that the destruction of force majeure from having reserved regulating quantity.
Design philosophy key of the present invention is: described no hangnail brilliance post pricker pin hole (4) is to stay after pressing molten cooling by the pricker of no hangnail brilliance cylinder; Pressing the hole depth after melting is 0～H, regulates according to the parameter that requires; Pressing the h after melting is 0～H, regulates according to the parameter that requires; Pressing molten temperature is 110～330 ℃; Density is 0 ~ 100000 pin/m2.
Design philosophy key of the present invention is: described no hangnail brilliance post pricker at work, make high and low fusing point short fiber in pressurized moment fast thawing; After the cooling high-melting-point short fiber that is damaged is fixed together again, and single fiber length is strengthened; Thereby significantly improve geotextiles intensity.
Design philosophy key of the present invention is: described low melting point short fiber, after geotextiles is finished whole acupuncture typings; Also to when increasing geotextiles density, make equally distributed low melting point short fiber fusing through the heat shrink typing; Heating-up temperature is higher than low melting point short fiber fusing point; Be lower than high-melting fibre, heating-up temperature be 110～230 ℃ according to the need adjustment.
