It is few to be made up of two gears and two pairs of rollers, double wedge is intermeshed wherein two gears are concave tooth, makes continuous fiber Shu Jing
Gear engagement backfin effect, assigns the kenel of its crimp shape, another one pair of which roller is by a rubber roller and metallic roller institute
The speed difference roller group of composition, using the characteristic of two roller different surfaces speed, open long-fiber bundle friction and dissipate into like single fiber shape,
By paving, repeatedly roller will open scattered long fibre paving repeatedly networking afterwards, be used for non-woven reinforcement；It is characterized in that：First non-woven is put
On the screen of bottom, restart long fine device, long fine coiled hair is driven through motor, make long fibre by friction fibrillation roller, by long fibre
Beam open it is scattered, then by paving change roller make it is long fine into round paving repeatedly on non-woven.
This process has two running motors, first, band dynamic friction fibrillation roller, second, driving paving repeatedly roller, starter motor is extremely
Reaching setting speed about needs 10sec, spreads the roller that changes to prevent long fibre from knotting or being coiled in, therefore first start the horse for spreading the roller that changes
Reach, restart the motor of friction fibrillation roller after about 5sec, and the former rotating speed need to be fast compared with the latter；Finally, long fine paving is repeatedly completed
Afterwards, upper strata non-woven is covered and reinforced again by tailor's cushion method.
Beneficial effect：Due to employing friction fibrillation plate reinforcement method in the present invention, so long fine uniformity is improved, product
Mechanical performance is also significantly increased, and required equipment is few, and can be reequiped in the case of production line operation is not influenceed.Applying
On the stress of concentration can be disperseed, it is reduced or is made Stress decomposition, and prevent the soil body by external force action breaks down, suitable for taking precautions against natural calamities
Engineering, Geotechnical Engineering, civil engineering, highway engineering, environmental project, hydraulic engineering and other related to native stone, underground water apply
In work.
Brief description of the drawings
Fig. 1 is the friction fibrillation plate reinforcement method schematic diagram of the embodiment of the present invention.
Embodiment
The present invention is described in further detail below by way of specific embodiment.
The preparation method of the fine reinforcement geotextile of length of the present embodiment, must first reequip non-woven preparation flow board first,
The device for opening scattered long-fiber bundle is set up above the screen of bottom, as shown in figure 1, the device is at least by two gears and two pairs of roller institute structures
Into, double wedge is intermeshed wherein two gears are concave tooth, make continuous fiber beam through gear engagement backfin effect, it is curly to assign its
Curved kenel, the speed difference roller group that another one pair of which roller is made up of a rubber roller and metallic roller, this composition
Function Characteristics, be the characteristic using two roller different surfaces speed, open long-fiber bundle friction and dissipate into like single fiber shape, after by
By paving, repeatedly roller will open scattered long fibre paving repeatedly networking, be used for non-woven reinforcement.Preparation method is that non-woven first is placed on into bottom
On screen, restart long fine device, long fine coiled hair is driven through motor, long fibre is opened long-fiber bundle by friction fibrillation roller
Dissipate, then repeatedly roller makes length fine into round paving repeatedly on non-woven by paving.This process has two running motors, first, band dynamic friction
Fibrillation roller, second, driving paving to change roller, starter motor about needs 10sec to setting speed is reached, in order to prevent it is long fine knot or
Paving repeatedly roller is coiled in, therefore first starts the motor for spreading the roller that changes, restarts the motor of friction fibrillation roller after about 5sec, and it is preceding
The rotating speed of person need to be fast compared with the latter.Finally, after the completion of long fine paving changes, upper strata non-woven is covered and reinforced again by tailor's cushion method.
This mode compared with not opening scattered long-fiber bundle, open dissipate after long fibre can promote with the property be entangled with of non-woven chopped fiber and uniformly
Property, and repeatedly networking kenel is that round anisotropy paving changes to this paving, up to the reinforcement of scalar property, avoids unidirectional reinforcement.
Fig. 1 is the friction fibrillation plate reinforcement method schematic diagram of the present embodiment.In figure, the 1 fine coiled hair of length；2 friction fibrillation rollers；3 pavings
Repeatedly roller；4. non-woven；5 bottom screens；The upper guide plate of 6 needle rolling machine 7；8 bottom guides.
It is also one of mode of improving performance to change structure, and the geotextile of single type can not meet in engineering sometimes
Needed for performance, it is necessary to by two or more difference in functionality and different types of geotextile with other materials is compound mutually reaches
To the effect of complementation.It is of the invention to utilize long fine reinforcement geotextile, it is in a manner of paving changes, to be held by upper and lower plane materiel by sandwich structure
Increase the distance of plane materiel up and down and resistance shearing by the load in plane and moment of flexure, and by core, wherein core then passes through
Friction fibrillation plate reinforcement method long-fiber bundle is opened it is scattered, except can improve uniformity and with addition to the associativity of plane materiel, the benefit of scalar property
It is strong that mechanical strength is also significantly increased.
It is of the invention as shown in table 1 with the test result of commercially available geotextile (PET non-woven geotextiles).
The test result of table 1
The technological thought of above example only to illustrate the invention, it is impossible to protection scope of the present invention is limited with this, it is every
According to technological thought proposed by the present invention, any change done on the basis of technical scheme, the scope of the present invention is each fallen within
Within；The technology that the present invention is not directed to can be realized by prior art.
