As shown in Fig. 2 (A), between warp 12 and the parallel 14 of the fabric 10 before fibrillation, there is big gap.And, Fig. 2 (B) and Fig. 2 (C) is compared, before fibrillation, makes compared with relatively low tension force acts on warp 12, do not have the parallel 14 of the free state of tension force effect somewhat to be strutted with by transport portion 170.The parallel 14 of free state owing to have received the tension force acted on warp 12 from the contact surface with warp 12, thus softened.

Fig. 3 is the view that the schematic cross-section to Fig. 2 (C) is amplified.As it is shown on figure 3, the warp 12 of the fabric 10 before fibrillation is made up of the strand of multifilament 16 boundling.Strand before fibrillation is generally circular, and two the most adjacent warps are the most farther apart, there is bigger difference in height between warp 12 and parallel 14.It addition, the warp 14 of the fabric 10 before fibrillation is also made up of the strand of multifilament 16 boundling.It addition, for the monofilament 16 in schematic cross-section, not use oblique line in order to be shown clearly in, but it be solid.Multiple figures afterwards are also so.

Fabric 10 is made into by inorfil or organic fiber.Inorfil can use carbon fiber, glass fibre etc..Carbon fiber can be asphalt base carbon fiber, PAN base carbon fibre etc..The composition of glass fibre can be the E glass of alkali-free glass, low dielectric glass, high-modulus glass etc..Organic fiber can use aromatic polyamide fibre, aromatic polyamide fibre, polyester fiber etc..In the present embodiment, E glass fibre woven into fabric 10 is used.The filament diameter of the fabric 10 of E glass fibre can be that 4 μm are to 7 μm.The boundling radical of each strand of fabric 10 can be 40 to 200.The thickness of fabric 10 is not particularly limited.It is about 10 μm to about 150 μm according to the thickness of the fabric 10 before fibrillation by the thickness of the fabric 10 of fiber-opening apparatus 100 fibrillation of present embodiment.The strand of the fabric 10 before fibrillation uses collecting agent to carry out boundling.The composition of the tunicle forming agent of collecting agent can be starch based or PVA (PolyvinylAlcohol) class.In the present embodiment, the fabric tissue of fabric 10 is the shown plain weaves such as Fig. 2, it is also possible to for twill, satin weave, three axle fabrics etc..It addition, in the case of using carbon fiber woven into fabric 10, filament diameter can be 6 μm to 10 μm, and the boundling radical of every strand can be 1000 to 24000.In the present embodiment, the most particularly limit, it is possible to use the fabric 10 of various filament diameters and boundling radical.

Pretreatment tank 110 and main treatment trough 120 can be steel, plastics system, fibre reinforced plastics system, stainless steel etc..Along direction D1, pretreatment tank 110 configures and abuts against the upstream of main treatment trough 120.Use 4 registration rollers 183,184,185,186, pretreatment tank 110 and the volume of main treatment trough 120 can not be increased, and by lengthening the transport path of the fabric 10 between pretreatment tank 110 and main treatment trough 120, fabric 10 can be kept for a long time to be in the state being immersed in treatment fluid 21.Further, press the fabric 10 in this transport path tactile by 4 registration rollers 183 etc., fabric 10 can be immersed in treatment fluid 21 effectively.Alternatively, it is also possible to carry out main process and pretreatment in same treatment trough.

Main treatment trough 120 has: the bottom 122 of the main treatment trough 120 of the most convex shape, load the mounting portion 124 of multiple oscillator unit 152 etc., and forms the sidepiece 126 of the side of main treatment trough 120.Mounting portion 124 is positioned at the position kept at a certain distance away with bottom 122, and the mesh that such as can be formed by multiple openings is formed, so that the treatment fluid 22 of supply unit 130 supply flows to discharge portion 142 described later.

Main treatment trough 120 is built-in with heater, and the temperature of the treatment fluid 22 of receiving can be set as 10 DEG C to 70 DEG C by heater, preferably 35 DEG C to 45 DEG C.In this temperature range, at least some of dissolving of the collecting agent being coated on fabric 10 can be made.Replace this structure or in addition, it is also possible to adjust the temperature of the newly supplied treatment fluid 22 of supply unit 130, the treatment fluid 22 in main treatment trough 120 is set as this temperature range.

The newly supplied treatment fluid 22 of supply unit 130 can be water or organic solvent, and pure water is preferably used.

Inner surface polytetrafluoroethylene (Teflon, the registered trade mark) processing of main treatment trough 120.Accordingly, the collecting agent being possible to prevent from the surface dissolution of fabric 10 to treatment fluid 22 is attached on the inner surface of main treatment trough 120.And, the discharge portion 142 of main treatment trough 120 is arranged on the foot of the bottom 122 with the most convex shape.Accordingly, the collecting agent from reprecipitation that passes through from the surface dissolution of fabric 10 to treatment fluid 22 can be promoted to discharge from discharge portion 142.It addition, main treatment trough 120 has outlet 144 further, outlet 144 is arranged on the position of height predetermined in sidepiece 126.

During fibrillation fabric 10, new treatment fluid 22 is continually provided to main treatment trough 120 by supply unit 130, treatment fluid 22 is discharged constantly by discharge portion 142 from main treatment trough 120, it is possible to the viscosity of the treatment fluid 22 in the main treatment trough 120 causing the collecting agent from the surface dissolution of fabric 10 to treatment fluid 22 improves and suppresses.Accordingly, the wavelength variation of ultrasound wave it is possible to prevent because of being possible to prevent the bubble residence in treatment fluid 22, it is possible to fibrillation efficiency low of suppression fabric 10.

Transport portion 170 transports fabric 10, and makes the treatment fluid 22 in its treatment fluid 21 immersing in pretreatment tank 110 and main treatment trough 120.Transport portion 170 includes the portion that unreels 171 and winding portion 172.Unreel portion 171 and winding portion 172 by have on warp direction the fabric 10 of about thousands of meters length on warp direction also can fibrillation effectively, and carry out unreeling and rolling under predetermined low-tension.Winding portion 172 fabric 10 after fibrillation can be dried after rolling again.It can be about 0.5m to 100m per minute that transport portion 170 transports the speed of fabric 10.

In the transport path of the fabric 10 transported by transport portion 170, it is configured with multiple registration rollers 181 etc..On the position of the fixed travel path change below the top of the liquid level of the treatment fluid that multiple registration roller 181 grades are rotatably arranged in each treatment trough and liquid level, to make fabric 10 be dipped in the treatment fluid 21 of pretreatment tank 110 while transporting fabric 10 by transport portion 170, make it be wetted in pretreatment tank 110, and immerse in the treatment fluid 22 of main treatment trough 120.

It is configured with multiple pressing levers 191 etc. between two registration rollers 186,187 of configuration below the liquid level of the treatment fluid in main treatment trough 120.Multiple pressing levers 191 etc. are arranged in the position avoiding each surface such as multiple oscillator unit 152 grade." surface " described here refers to that the major part of each pressing lever 191 grade deviates from the overhead projection face of oscillator unit 152 grade, it is also possible to include the situation that a part for each pressing lever 191 grade is overlapping with the overhead projection face of oscillator unit 152 grade.

Oscillator unit 151 in pretreatment tank 110 can be positioned on the bottom of pretreatment tank 110.Multiple oscillator unit 152 grade arranged on main treatment trough 120 is arranged in mounting portion 124 side by side along direction D1.Multiple oscillator unit 152 etc. can be fixed in mounting portion 124.It addition, in Fig. 1 and Fig. 7, in order to be shown clearly in, a part for multiple oscillator unit 152 grade in main treatment trough 120 is omitted, and the quantity of multiple oscillator unit 152 grades is not particularly limited.

Control portion 160 controls the multiple oscillator unit 151 etc. being separately positioned in pretreatment tank 110 and main treatment trough 120 by following various modes.First, the output intensity of multiple oscillator unit 152 grade arranged during control portion 160 makes main treatment trough 120 is equal to or more than the output intensity of the oscillator unit 151 arranged in pretreatment tank 110.In the case of making output intensity difference, the output intensity of multiple oscillator unit 152 grade in main treatment trough 120 is controlled the high output for making fabric 10 fibrillation by control portion 160, controls the output intensity of the oscillator unit 151 in pretreatment tank 110 for make treatment fluid 21 infiltrate the low output in the space to fabric 10.Accordingly, the air contained in a large amount of gaps between multiple strands of the fabric 10 before fibrillation and between the multifilament forming each strand, it is replaced as treatment fluid 21 by pretreatment before fabric 10 fibrillation, can suppress to remain in the bubble in fabric 10 by main process when fabric 10 fibrillation, the fibrillation that therefore, it can reduce fabric 10 is uneven and improve fibrillation efficiency.The frequency of multiple oscillator unit 151 grades can be 10kHz to 200kHz.The output intensity of multiple oscillator unit 151 can be controlled by control portion 160.The output density of multiple oscillator unit 151 grades can be about 30W/L to 60W/L.

During transporting in by the transport portion 170 treatment fluid 22 in fabric 10 immerses main treatment trough 120, control portion 160 stops the vibration of multiple oscillator unit 152 grade the direction from upstream toward downstream of direction D1 successively according to each unit, it is again turned on the vibration of multiple oscillator unit 152 grade stopped the most again with identical order, so repeats.Control portion 160 coordinates the travelling speed of fabric 10 to carry out sequential control with the opportunity to the vibration sequentially stopping/be again turned on multiple oscillator unit 152 grade.By the vibration of oscillator unit 152 grade, the multiple bubbles adhering to/being detained on fabric 10 are made to be discharged by ultrasonic activation so that it is the flow further downstream along with the flowing of fabric 10.Accordingly, be possible to prevent to suppress the fibrillation of fabric 10 because of multiple bubbles, therefore, it can reduce fabric 10 fibrillation uneven and improve fibrillation efficiency.It addition, control portion 160 can stop according to the group of the above unit of each two/be again turned on the vibration of multiple oscillator unit 152 grade successively.

Further, from the oscillator unit 153 etc. of oscillator unit 152 grade of the upstream side of direction D1 to downstream, control portion 160 makes the output intensity of multiple oscillator unit 152 grade become big according to each unit.Accordingly, can be along with the transport in downstream, fibrillation fabric 10 at leisure, therefore, it can reduce fabric 10 fibrillation uneven and improve fibrillation efficiency.It addition, control portion 160 can also make the vibration of multiple oscillator unit 152 grade become big according to the group of the above unit of each two successively.

So, for the fabric 10 before the fibrillation shown in Fig. 2 and 3, the boundling state of each monofilament 16 of warp 12 and parallel 14 is released by pretreatment portion 101 and main process portion 102, the former rectilinear recuperability of return and the transport portion 170 that are respectively provided with by warp 12 and parallel 14 apply the low tension force to warp 12, make warp 12 and parallel 14 strut mutually.Multiple monofilament 16 launch in the way of landfill is in gap and configure, and make the strand flattening after fibrillation accordingly.

Fig. 4 is the explanatory diagram of the fabric 10 after fibrillation is described, Fig. 5 is the schematic cross-section of the fabric 10 after fibrillation.

Identical with Fig. 2 (A) to Fig. 2 (C), Fig. 4 (A) is the floor map of fabric 10, Fig. 4 (B) is the schematic cross-section making fabric 10 rupture on the bearing of trend of the warp 12 of the fabric 10 at Fig. 4 (A), and Fig. 4 (C) is the schematic cross-section making fabric 10 rupture on the bearing of trend of the parallel 14 of the fabric 10 at Fig. 4 (A).

As shown in Fig. 4 (A), for the fabric 10 after fibrillation, the big gap existed between warp 12 and the parallel 14 of the fabric 10 before fibrillation, by minimization, there's almost no gap in fabric 10 in plan view.It addition, as shown in Fig. 4 (B) and Fig. 4 (C), warp 12 and parallel 14 are softened with the degree being substantially the same.

Fig. 5 is the view amplified to illustrate in greater detail the schematic cross-section of Fig. 4 (C).As it is shown in figure 5, by fibrillation, the difference in height between warp 12 and parallel 14 almost disappears, being smoothed of fabric 10/thinning.And, by reducing gap, improve the insulating reliability of fabric 10, thickness that the most very thin chemical conversion is identical with film and also may insure that high insulating reliability.And, because with the fabric of the non-fibrillation of the boundling number with multiple monofilament 16 or identical with general fabric, even if making such very thinization of fabric 10, it is also possible to keep rigidity.And, by by warp 12 and parallel 14 equally abundant fibrillation, the density difference in the face of fabric 10 can be reduced and improves homogeneity, accordingly, can improve the processability of the fabric 10 using laser etc..

Fig. 6 is the close-up schematic view that explanation is in the position that the fabric 10 of the state immersed in treatment fluid passes through.Transport portion 170 transports fabric 10, in order to fabric 10 is in the antinode according to the standing wave 30 obtained between surface and the liquid level 25 for the treatment of fluid 22 of corresponding oscillator unit 152 grade in each ultrasonic activation produced of multiple oscillator unit 152 grades.The position amplitude of the antinode of standing wave 30 is maximum and intensity is very big, therefore becomes the maximum impact position of ultrasound wave.In main treatment trough 120, in any position of direction D1, the waveform of standing wave 30 is all identical, and the frequency of multiple oscillator unit 152 grade in main treatment trough 120 is the most identical.It addition, the antinode of standing wave 30 can comprise a range of region, naturally it is also possible to be limited to not necessarily by the situation of a bit.

In order to the amplitude making standing wave 30 is maximum, the antinode of the transmitted wave 34 that the antinode of row ripple 32 that oscillator unit 152 etc. produces fixes end reflection with the liquid level for the treatment of fluid is consistent, makes row ripple 32 and transmitted wave 34 overlapping.Specifically, velocity of sound in treatment fluid 22 is assumed to 1500 [m/s], corresponding with preset frequency f [kHz] of oscillator unit 152 grade, the height h [mm] from the surface of oscillator unit 152 grade to liquid level 25 of the treatment fluid 22 in main treatment trough 120 is adjusted to meet with following formula 1 and formula 2, makes row ripple 32 and transmitted wave 34 overlapping.

λ [mm]=1500 [m/s]/f [kHz] formula 1

H [mm]=(λ/2) × n (n=1,2,3 ...) formula 2

The position of the antinode of standing wave 30, based on equation 1 above, is determined by distance Xn [mm] meeting the surface of distance oscillator unit 152 grade of following formula 3.

Xn [mm]={ (2n-1)/4} × λ (n=1,2,3 ...) formula 3

The transport path of fabric 10 is arranged under the liquid level 25 of the treatment fluid 22 in main treatment trough 120, and determines according to the position of two registration rollers 186,187 and multiple pressing lever 191 etc..Therefore, adjust the position of two registration rollers 186,187 and multiple pressing lever 191 etc., so that fabric 10 is by distance Xn (mm) calculated according to above-mentioned 3.Accordingly, the impact of maximum can be applied to fabric 10, and the fibrillation efficiency of fabric 10 can be improved to greatest extent.

As used illustrated by Fig. 1, according to present embodiment, outlet 144 being arranged at the predetermined height and position in the sidepiece 126 of main treatment trough 120, the flow making the treatment fluid 22 that the flow-rate ratio discharge portion 142 of the new treatment fluid 22 that supply unit 130 supplies discharges is bigger.Accordingly, because treatment fluid 22 overflows from outlet 144, it is possible to this predetermined height will be securely maintained at from the height h (mm) on the surface of multiple oscillator unit 152 grades to the liquid level 25 for the treatment of fluid 22.

And, in main treatment trough 120, supply from the new treatment fluid 22 of supply unit 130 is carried out under liquid level 25, the treatment fluid 22 in the discharge portion 142 arranged on the bottom 122 of the most autonomous treatment trough 120 is discharged, and makes the treatment fluid 22 of the outlet 144 arranged at comfortable sidepiece 126 overflow simultaneously.Accordingly, liquid level 25 can be made stable statically, therefore, it can make aforesaid maximum impact position stable.

Based on equation 3 above, the position of distance Xn (mm) on the surface of distance oscillator unit 152 grade, in order to be defined as the maximum impact position of ultrasound wave, therefore carries out following experiment.First, in oscillator unit 152 grade of 28kHz, distance h (mm) on the surface of oscillator unit 152 grade to the liquid level 25 for the treatment of fluid 22 is set at essentially the 54mm meeting equation 1 above and 2, so that the amplitude of standing wave 30 becomes maximum.Therefore, configuration aluminium foil, to extend in the face of the surface normal of oscillator unit 152 grade, produces the ultrasonic activation from oscillator unit 152 grade.Therefore, at X₁=13mm and X₂The breakage of the aluminium foil of the position of=40mm is concentrated most.It is to say, determine that these positions are maximum impact positions.

And, as shown in Figure 6, multiple pressing levers 191 etc. are arranged in the position of the respective surface avoiding multiple oscillator unit 152 grade, say, that the major part of each pressing lever 191 grade is arranged in the position that the overhead projection face with multiple oscillator unit 152 grades drifts out.Thereby it can be assured that distance h (mm) between surface and the liquid level 25 for the treatment of fluid 22 of multiple oscillator unit 152 grade in main treatment trough 120 can make fabric 10 by the maximum impact position calculated according to preceding method.

Fig. 7 is the explanatory diagram of the arrangement that multiple oscillator unit 152 grade is described.In figure, the arrow of blacking illustrates direction D2 orthogonal with direction D1 in a horizontal plane.

As shown by Fig. 7 dotted line, each of multiple oscillator unit 152 grades equally spaced accommodates multiple oscillators with mutually the same shape/size in equal number ground.If being conceived to multiple oscillator, being positioned in the multiple oscillators in the mounting portion 124 of main treatment trough 120, in addition to the configuration of direction D1, being arranged in the most side by side in the D2 of direction.The multiple oscillators accommodated in one oscillator unit 152 grade of multiple oscillator unit 152 grade extended in the D2 of direction, relative to the multiple oscillators accommodated in adjacent oscillator unit 153 grade, are offsettingly arranged in the D2 of direction.Accordingly, can similarly transmit the energy of ultrasonic activation on whole of fabric 10, can suppress to apply pressure to fabric 10.Therefore, it can suppression on fabric 10, produce fold, it is thus possible to suppression generation fibrillation on fabric 10 is uneven.

Fig. 8 is the schematic diagram of other fiber-opening apparatus 200 making fabric 10 fibrillation.In fig. 8, the transport path that transport portion 170 is mainly transported fabric 10 illustrates, and will omit other structures.In addition in main treatment trough 220, the transport path of fabric 10 is multisection type, fiber-opening apparatus 200 has the structure identical with fiber-opening apparatus 100.

As shown in Figure 8, by configuring in vertical direction by the multiple registration rollers 280 under the treatment fluid liquid level in main treatment trough 220 and multiple pressing lever 290 multistage, the transport path of the fabric 10 in main treatment trough 220 can become multisection type.And, these subsurface multiple registration rollers 280 and multiple pressing lever 290 are arranged in the position of the surface avoiding multiple oscillator unit 250, further, fabric 10 is arranged at predetermined height and position (in fig. 8, it is arranged in the position of n=1,2,3 in the Xn of above-mentioned formula 3), in order to by using the maximum impact position of the ultrasound wave of Fig. 6 explanation.Thus, energy-saving can be realized according to the fiber-opening apparatus 200 of present embodiment.

According to the fiber-opening apparatus in above-mentioned multiple embodiments, compared with existing fiber-opening apparatus, the quality of the fabric after fibrillation improves.Specifically, during fibrillation, the collecting agent of dissolution is smoothly discharged out, and improves fibrillation rate, the bubble that when can effectively remove fibrillation, fabric produces.Therefore, it can significantly decrease fibrillation and hinder uneven with fibrillation.
