Abstract
The invention discloses a technology for manufacturing strong non-woven cloth, which is characterized by folding four layers of non-woven cloth, needling to obtain needled non-woven cloth, additionally paving fiberglass gridding cloth on the surface of the needled non-woven cloth, and interweaving the fiber of the fiberglass gridding cloth and the fiber of the non-woven cloth together in a needling way. According to the technology, not only is the overall strength of a material improved, but also the separation of the non-woven cloth away from fiberglass grids is prevented; therefore new type non-woven cloth which is strong in tensile force and is closely connected into a whole is manufactured.
Description
Technical field
The present invention relates to nonwoven fabric and make field, in particular to a kind of manufacture craft of reinforcing nonwoven fabric.
Background technology
Nonwoven fabric claims again Nonwovens, is to be made up of the fiber of qualitative or random alignment, has the multiple advantages such as protection against the tide, ventilative, pliable and tough, light weight, is environment-friendly materials of new generation, has many important application in industry or sphere of life.Such as, in building trade, for the malthoid of waterproof, exactly taking nonwoven fabric as carrier, on it, adhere to that pitch makes.But in the actual fabrication process of malthoid, adopt merely nonwoven fabric to soak in pitch, in drawing process due to nonwoven fabric insufficient strength, thereby there will be the phenomenon of nonwoven fabric fracture interruption of work.In order to increase the tensile force of nonwoven fabric, people adopt bonding method that two nonwoven fabric are bonded in to glass fiber reticular cloth two sides, and nonwoven fabric soaks and when pulled, can not occur the phenomenon of fracture again in pitch like this.But this kind of material due to surperficial nonwoven fabric and middle glass fiber reticular cloth convergent-divergent coefficient different, adhere to pitch cooling after, often there is the bonding cracking of epidermis nonwoven fabric and glass fiber reticular cloth and separate, thereby lose the serviceability of this kind of material application.After this kind of material made, thickness is larger, be not suitable for occasion that the thinness of nonwoven fabric is had relatively high expectations, and cost of manufacture is high.
Therefore, research and development one had both had powerful tensile force, stop again that nonwoven fabric separates with glass fiber reticular cloth for making the manufacture craft of non-woven fabric of malthoid, just become this area and be badly in need of the technical problem solving.
Summary of the invention
The object of this invention is to provide a kind of manufacture craft of reinforcing nonwoven fabric, the nonwoven fabric tensile force that utilizes this technique to make is strong, and closely connects as one, and can not ftracture.
To achieve these goals, the present invention takes following technical scheme:
A manufacture craft for reinforcing nonwoven fabric, is characterized in that comprising the steps:
(a) terylene short fiber raw material is carried out to shredding and be carded to web;
(b) gained web is carried out folding, obtain folding web;
(c) folding web is carried out to acupuncture, the syringe needle of pricker used is conical, has hangnail on syringe needle, and pricker is fixed on needle plate, and thorn pin density is 6000 every square metre, and puncture frequency is 200 times per minute, obtains needle punched non-woven fabrics;
(d) in go forward side by side hand-manipulating of needle thorn of the attached glass fiber reticular cloth in gained needle punched non-woven fabrics upper berth, thorn pin density is 2000 every square metre, and puncture frequency is 150 times per minute, obtains grid nonwoven fabric;
(e) gained grid nonwoven fabric is carried out to HEAT SETTING under 200 degrees Celsius, obtain reinforcing nonwoven fabric finished product.
In such scheme step (b), preferably by folding web four times.
In the technical program, first make four layers of nonwoven fabric fold, then carry out acupuncture and obtain needle punched non-woven fabrics, add glass fiber reticular cloth needle punched non-woven fabrics surface paving again, and make fiberglass mesh and non-woven fabrics fiber weave in by the method for acupuncture, both strengthen the bulk strength of material, prevented again that nonwoven fabric from ftractureing and separating with fiberglass mesh, thereby made the non-woven fabric that tensile force connects as one by force, closely.In the time making malthoid, nonwoven fabric neither can rupture like this, the phenomenon that also there will not be glass fiber reticular cloth and needle punched non-woven fabrics to be separated, thereby the quality of raising malthoid.In addition, utilize this technique to produce, production efficiency is high, and speed of production is fast, and the product that production thin and thick simultaneously does not wait, had both enriched product category, had reduced again cost.
Brief description of the drawings
Fig. 1 is the device of the attached grid cloth of this technique middle berth.
Detailed description of the invention
Below in conjunction with accompanying drawing, invention is described further:
First, polyester staple fiber raw material is carried out to shredding, shredding becomes to be convenient to the filiform of combing, then carry out combing, numerous filiforms are carded to web, sometimes in order to gain in strength, two or three kind of different polyester staple fiber need to be carried out to shredding, then mix and be carded to web.Obtain after web, carry out lapping, repeatedly overlapping by web, increase the overlapping number of plies, be generally four layers, can be also more multi-layered, determine according to the thickness of required product and intensity, desired thickness and intensity are larger, need the overlapping number of plies more.
Overlapping web is carried out to acupuncture by needing machine, generally adopt four row's needing machines to carry out successively acupuncture, pricker is fixed on needle plate, the syringe needle of pricker is conical, and on it, with hangnail, hangnail can hook anti-fiber, thereby be woven, to strengthen firm degree.On needle plate, the density of pricker is 6000 of every square meters, and puncture frequency is 200 times per minute, and experiment is pointed out, thorn pin density is less than 6000, a little less than the degree of fiber entanglement, is unfavorable for strengthening fastness, if density higher than 6000, tends to fiber thorn section, thereby sharply reduce the toughness of cotton; Puncture frequency is less than 200 times per minute, makes acupuncture number of times less, is unfavorable for Filament-wound Machine, and frequency is greater than 200 times, and the suffered pricker impact of fiber is excessive, and easily fracture, reduces toughness of products.Through after this procedure, obtain needle punched non-woven fabrics.
Fig. 1 is the device of the attached grid cloth of this technique middle berth.Outside the first supporting-point roller group 4, glass fiber reticular cloth to be installed supporting-point roller 1 is provided, glass fiber reticular cloth 2 is wound on glass fiber reticular cloth and provides on supporting-point roller 1, then glass fiber reticular cloth 2 is passed through to the first supporting-point roller group 4.The needle punched non-woven fabrics 3 of anticipating is after the first supporting-point roller group 4, fit together with glass fiber reticular cloth 2, then pass through needling device 5, by acupuncture, the fiber interweaving that the fiber of glass fiber reticular cloth 2 is convenient to needle punched non-woven fabrics 3 is intertwined, after the second supporting-point roller group 6, obtain novel reinforcing nonwoven fabric 7, this reinforcing nonwoven fabric is because appearance has glass fiber reticular cloth, intensity is large, tensile force is strong, and due to acupuncture effect, not can with lower floor's nonwoven fabric craze and transfiguration.This road spreads the operation of attached grid cloth to carry out after obtaining needle punched non-woven fabrics, on needle plate, the density of pricker is 2000 of every square meters, density is excessive, and easily, by disconnected the glass fibre thorn of grid cloth, density is too little cannot be attached on needle punched non-woven fabrics strong grid; Based on same reason, puncture frequency is decided to be 150 times per minute.After this procedure, obtain grid nonwoven fabric.
Finally, under 200 degrees Celsius, grid nonwoven fabric is carried out to HEAT SETTING, obtain reinforcing nonwoven fabric finished product.
