Abstract
The invention provides polyoxy methylene fiber needle-punched non-woven geotechnical cloth and a manufacturing method thereof. The needle-punched non-woven geotechnical cloth has the advantages of being large in breaking force, high in bursting resisting capacity, resistant to alkaline corrosion, high in ageing resistance and excellent in abrasion resistance. The manufacturing method includes the following steps of 1, a fiber preprocessing stage, wherein polyoxy methylene filaments are curled and cut off to obtain short curled fibers, and the curling degree of the fibers ranges from 20% to 30%; 2, a geotextile manufacturing stage, wherein the short curled fibers are manufactured into the polyoxy methylene fiber needle-punched non-woven geotechnical cloth.
Description
Technical field
The present invention relates to a kind of without spinning geotextile, more specifically relate to a kind of polyoxymethylene fiber needle non-woven geotextile and its preparation method, belong to civil engineering material field.
Background technology
Along with the exploitation energetically of country's Infrastructure in hydro project, highway, railway, environment protection etc.; geotechnique's textiles is more widely used and develops rapidly; wherein synthetic staple fibers needling nonwoven geotextiles is current most widely used main kind, and the raw material selected by current synthetic staple fibers needling nonwoven geotextiles is polypropylene fibre and terylene mainly. Because the restriction of raw material self performance, the performance boost space of geotextile is less: patent documentation CN102454046A discloses a kind of method manufacturing high-strength needling nonwoven geotextiles, polypropylene fibre is adopted to there is shortcoming powerful on the low side, patent documentation is mentioned simultaneously and trevira can be adopted to produce, there is the defect of alkali corrosion resistance poor-performing in it, the production technique more complicated of this needling non-woven geotextile manufacture method and energy consumption height. The common non-geotextile of weaving of above Problems existing can not solve, more cannot meet design, user demand that high ferro, motorway, airport, great hydro project etc. improve day by day. It is therefore desirable to promote its over-all properties in essence from geotextile.
Summary of the invention
Goal of the invention
It is an object of the present invention to provide the preparation method of a kind of polyoxymethylene fiber needle non-woven geotextile, gained needling non-woven geotextile has ultimate strength ability height big, anti-bursting, alkali corrosion resistance, resistance of aging is strong, wear resisting property is excellent feature.
It is a further object to provide the polyoxymethylene fiber needle non-woven geotextile that described preparation method obtains.
Invention general introduction
In a first aspect of the present invention, it provides the preparation method of a kind of polyoxymethylene fiber needle non-woven geotextile, comprises the steps:
(1) fiber pretreatment stage: polyoxymethylene crimped filament, cut-out are obtained curling staple fibre, fibrous crimpness 20%��30%;
(2) the geotextile manufacturing stage: described curling staple fibre is made polyoxymethylene fiber needle non-woven geotextile.
It is prior art that the described geotextile manufacturing stage makes the method for needling non-woven geotextile, and concrete can be: described curling staple fibre is through shredding, mixing, carding, lapping, the obtained polyoxymethylene fiber needle non-woven geotextile of acupuncture. Described shredding can be divided into thick shredding, essence shredding.
Preferably, the diameter of described polyoxymethylene long filament is 15��40 microns, it is more preferable to be 15��30 microns.
The dynamic friction factor of polyoxymethylene fiber is little, smoothness is good, it is unfavorable for obvolvent, and rigidity (Young's modulus) is bigger, overlap joint performance between fiber is lower, in the not easily continuous formation conveying of carding operation, the became uneven of lapping can be caused, it is difficult to obtained needling non-woven geotextile. Fiber is carried out pre-crimped process by the present invention, just can realize lapping evenly to lapping operation through shredding, mixing, carding, thus finally farthest be realized in finished product by the excellent properties of fiber so after the pre-treatment. Pre-crimped is treated to this area common method, owing to the too high meeting of crimpness significantly reduces the over-all properties of finished product geotextile, the related request that cannot be up to state standards, therefore in prior art the crimpness general control of pretreated polypropylene, trevira 10%��15%. Investigator of the present invention surprisingly finds, polyoxymethylene fibrous crimpness is promoted to 20%��30%, its armful and, overlap joint performance be improved significantly, effectively ensure the homogeneity of lapping, the obtained polyoxymethylene fiber needle non-woven geotextile of success, and product performance are excellent.
In the another aspect of the present invention, additionally provide the polyoxymethylene fiber needle non-woven geotextile that above-mentioned preparation method obtains.
The present invention adopts polyoxymethylene fiber as the starting material of geotextile, and tensile strength is doubled and redoubled compared with the material such as polypropylene, trevira, is about 2 times of trevira, 3 times of polypropylene fibre. The embodiment of the high-tensile of starting material fiber in finished product geotextile is exactly the significantly lifting of the mechanical performance index such as breaking tenacity, bursting strength. The Young's modulus height of polyoxymethylene fiber is 4 times of polypropylene fibre, higher than trevira by 50%, and after acupuncture becomes geotextile, its ability resisting deformation is stronger. The rub resistance abradability of polyoxymethylene fiber is excellent, static friction factor 0.290 (polyester 0.375, nylon-20 .405), dynamic friction factor 0.245 (polyester 0.355, nylon-20 .360). Because geotextile often carries out with alkaline concrete construction simultaneously, and the alkali corrosion resistance of polyoxymethylene fiber excellence is far better than trevira, therefore polyoxymethylene fiber needle non-woven geotextile of the present invention has ultimate strength ability height big, anti-bursting, alkali corrosion resistance, resistance of aging is strong, wear resisting property is excellent feature. Preparation method's technique of the present invention is simple simultaneously, energy consumption is low, makes finished product geotextile have higher cost performance.
Embodiment
The present invention is further described below, but described embodiment is only for the present invention instead of restriction the present invention by embodiment.
Following examples adopt commercially available common polyoxymethylene long filament as raw material, and its performance perameter is: tensile strength > 1300MPa, Young's modulus 25GPa.
