Next, an embodiment of the present invention will be described with reference to the drawings.

The yarn spinning device (yarn forming device) 1 shown in FIG. 1 is a CNT yarn 10 that is drawn out from the CNT substrate 3a and wound up.

The CNT substrate 3a is a raw material for supplying textiles, that is, CNT. The CNTs are a plurality of surfaces arranged side by side on the thickness direction side of the CNT substrate 3a to constitute the CNT array 32. Each CNT faces the surface of the CNT substrate 3a almost perpendicularly.

CNT is a fiber group (CNT fiber group 30) formed as an aggregate, and is extracted from the CNT substrate 3a. The direction in which the CNT fiber group 30 is extracted from the CNT substrate 3a is a direction substantially parallel to the surface of the CNT substrate 3a. The CNT fiber group 30 is extracted from the surface of the CNT substrate 3a by a predetermined width, and becomes a thin sheet as a whole. In the CNT fiber group 30, a large number of CNTs are juxtaposed in the width direction. In addition, in the CNT fiber group 30, each CNT is oriented almost parallel to the direction to be extracted, and is successively extracted while being connected in the longitudinal direction. Hereinafter, the CNT fiber group 30 thus extracted is also referred to as a CNT net 33.

The yarn spinning device 1 mainly includes a substrate fixing portion 11, a textile portion 12, and a winding portion 13.

Hereinafter, in the description of the yarn spinning device 1, "upstream" and "downstream" refer to the directions in which the CNT fiber group 30 and the CNT yarn 10 travel during the spinning process of the CNT yarn 10 by the yarn spinning device 1. Upstream and downstream mean. The textile section 12 is arranged on the downstream side of the substrate fixing section 11, and the take-up section 13 is arranged on the downstream side of the textile section 12.

The substrate fixing portion 11 can be attached to and removed from the CNT substrate 3a. The substrate fixing portion 11 keeps the assembled CNT substrate 3a stationary when the CNT net 33 is pulled out from the CNT substrate 3a.

Before the CNT substrate 3 a is assembled in the substrate fixing portion 11, a predetermined preparation operation is performed in advance. Thereby, the extraction end 35 shown in FIG. 2 is formed in the CNT substrate 3a. This extraction end 35 includes a CNT mesh 33 that is extracted from the CNT array 32 formed on the substrate 31 of the CNT substrate 3 a, and a yarn-shaped CNT portion 34 that is formed at the tip of the CNT mesh 33 that is formed in the extraction direction.

The CNT net 33 is a network-shaped aggregate formed by aligning CNTs, and is connected to the CNT array 32.

The yarn-shaped CNT portion 34 is formed in a linear shape by collecting the leading end portions of the CNT net 33 in the width direction and shortening them. CNTs are easily aggregated by intermolecular forces, and the aggregation is irreversible. Therefore, the yarn-shaped CNT portion 34 is not disentangled without using a binder or the like. In the present invention, agglutination refers to a bonding phenomenon caused by the stabilization of the energy generated by the van der Waals force because the atoms on the surface of the CNT are coordinately unsaturated, and thus coordinate with each other.

In this way, by forming the extraction end 35 (yarn-shaped CNT portion 34) in advance on the CNT substrate 3a, the yarn spinning device 1 can supply the CNT fiber group 30 in the CNT net by supplying the extraction end 35 of the CNT substrate 3a to the textile portion 12. In the state of 33, the CNT substrate 3a is pulled out, and the spinning operation is started smoothly. As a result, handling of CNTs becomes easy, and convenience in spinning can be improved.

The preparation work of the CNT substrate 3a is performed by the CNT substrate extraction end preparation device 2 shown in FIG. 3. The yarn spinning device 1 and the CNT substrate extraction end preparation device 2 constitute a textile system of this embodiment. The detailed configuration of the CNT substrate extraction end preparation device 2 will be described later.

The textile unit 12 in FIG. 1 forms a CNT yarn 10 by orbiting an air flow to the CNT fiber group 30 drawn out from the CNT substrate 3a. The orbiting air flow for applying false twisting can be generated by supplying compressed air to the textile section 12.

The winding section 13 winds the CNT yarn 10 formed by the textile section 12 on a winding tube (not shown) to form a package.

An intermediate conveying section 14 is provided between the textile section 12 and the winding section 13. As shown in FIG. 1, the intermediate conveying section 14 is composed of two pairs of rollers 14 a and 14 b, and conveys the CNT yarn 10 formed by the textile section 12 toward the winding section 13. The rollers 14a and 14b are arranged to be gripped by the CNT yarn 10, and are driven to rotate at a predetermined rotation speed. Thereby, a predetermined tension can be applied to the CNT yarn 10 and the CNT yarn 10 can be drawn out at a predetermined speed.

Next, the CNT substrate extraction end preparation device 2 will be described with reference to FIG. 3. The CNT substrate extraction end preparation device 2 mainly includes a base member 20, a substrate support portion 4, a scraping portion (first extraction portion) 5, a winding extraction portion (second extraction portion) 6, and a collection portion. (Unification Department) 7.

In the following description, the “extraction direction” in the description of the CNT substrate extraction end preparation device 2 means that the CNT fiber group 30 (CNT net 33) is extracted from the CNT substrate 3 by the scraping section 5 and the winding extraction section 6. The meaning of the direction.

The base member 20 is formed of a linear elongated plate-shaped member. The length direction of the base member 20 is arranged parallel to the direction (drawing direction) in which the CNT net 33 is pulled out from the CNT substrate 3.

The substrate supporting portion 4 is an end portion attached to the base member 20 in the longitudinal direction. The CNT substrate 3 can be attached to and detached from the substrate supporting portion 4. The substrate support portion 4 keeps the assembled CNT substrate 3 stationary when the CNT fiber group 30 is withdrawn by the scraping portion 5 or the take-up and withdrawal portion 6. Although various configurations of the substrate support portion 4 are conceivable, for example, as shown in FIG. 3, it is conceivable to hold the plurality of holding members 41 in contact with the outer peripheral surface of a substrate 31 described later.

The CNT substrate 3 has a structure in which a plurality of CNTs are arranged in a CNT array 32 arranged side by side on a surface in the thickness direction of the substrate 31 serving as a base material. The substrate 31 is made of, for example, a material such as glass, silicon, or metal. The CNT array 32 is formed on the substrate 31 by, for example, a chemical vapor growth method. Each CNT constituting the CNT array 32 has a length of about 1 mm, for example, and faces the substrate 31 almost perpendicularly.

The CNT substrate 3 is horizontally assembled to the substrate support portion 4 with the CNT array 32 positioned on the upper surface side. The CNT substrate 3 of this embodiment is formed in a circular shape. However, it is not limited to this, and other shapes of the CNT substrate 3 may be used.

The CNT substrate extraction end preparation device 2 prepares the CNT net 33 from the assembled CNT substrate 3 in a net shape. In the following description, the "net width direction" means the width direction of the CNT net 33 that is extracted. The “mesh thickness direction” means the thickness direction of the CNT mesh 33 that is extracted. In the CNT substrate extraction end preparation device 2 of this embodiment, the web width direction is horizontal (parallel to the surface of the CNT substrate 3), and the web thickness direction is vertical.

As shown in FIG. 3, the scraping part 5 includes a base part 51, a scraping arm 52, and a comb-shaped tooth member (extracting member, first member) 53.

The base portion 51 is provided on the downstream side of the substrate support portion 4 in the extraction direction. The base portion 51 is configured to be slidably movable in a direction parallel to the longitudinal direction of the base member 20 through a slide mechanism (not shown). Although not shown, in order to slide the base portion 51, an appropriate actuator (scraper slide driving portion) including an electric motor or the like is provided. Thereby, the scraping-out part 5 can approach or separate from the board | substrate support part 4.

The base portion 51 is configured to be rotatable around an axis (not shown) parallel to the screen width direction through a rotation mechanism (not shown). The base portion 51 is movable between an operating position close to the substrate support portion 4 and a retracted position away from the substrate support portion 4 obliquely by a suitable actuator (not shown). In FIG. 3, the base portion 51 is shown in a retracted position.

The scraping arm 52 is rotatably supported by the base portion 51. The scraping arm 52 can be rotated by a predetermined angular stroke by a suitable actuator (not shown).

The comb-shaped tooth member 53 is fixed to the tip of the scraping arm 52. The comb-shaped tooth member 53 is composed of a metal plate-shaped member. As shown in FIG. 4, in the comb-shaped tooth member 53, the teeth 54 having the same shape are formed on the side opposite to the side fixed to the scraping arm 52, and are teeth rows 55 that are linearly overlapped and overlapped. The direction in which the teeth 54 are juxtaposed is parallel to the screen width direction.

In the above configuration, the base portion 51 is slidably moved close to the substrate support portion 4 and, when the base portion 51 is in the operating position, the scraping arm 52 is rotated, as shown in FIG. The tip end (tooth row portion 55) of the tooth member 53 is in contact with the CNT array 32 formed on the CNT substrate 3. In this state, if the base portion 51 slides away from the substrate support portion 4, the CNTs 33 are scraped from the CNT array 32 by the comb-shaped tooth member 53, and the CNT net 33 can be extracted from the CNT substrate 3.

On the other hand, when the base part 51 is located in the retracted position shown in FIG. 3, the scraping part 5 may not interfere with the operation of the take-up and extraction part 6 and the collection part 7.

The shape of the comb-shaped tooth member 53 will be described in detail with reference to FIG. 4. In the tooth row portion 55, a notch portion 56 is formed between adjacent teeth 54. The cutout portion 56 is formed to have a predetermined width W and a depth D.

In the CNT array 32, CNTs arranged adjacent to each other are pulled toward each other by an intermolecular force. Therefore, the CNT array 32 has appropriate viscosity. The width W of the cutout portion 56 is obtained when the comb-shaped tooth member 53 scrapes the CNT array 32. The viscosity of the CNT array 32 can be used to make the CNTs in the cutout portion 56 scraped by the teeth 54 CNTs can be extracted well. The comb-shaped tooth member 53 of this embodiment has, for example, a width of the teeth 54 of 0.5 mm, a width W of the cutout portion 56 of 0.5 mm, and a depth (in other words, a length of the tooth 54) D of the cutout portion 56 of 2 mm. However, it is not limited to this.

The depth D of the cutout portion 56 is greater than the length of the CNTs extending perpendicularly to the surface of the substrate 31. As a result, the CNTs located in the cutout portion 56 are in contact with the comb-shaped tooth member 53 and can be prevented from being crushed by the CNTs in the longitudinal direction. As a result, since the orientation of the CNTs does not hinder the alignment of the self-organized structure toward the extraction direction, the continuity of the CNTs can be ensured.

In this way, the CNTs of the CNT substrate 3 are extracted through the cutout portion 56 of the dentition portion 55. In the comb-shaped tooth member 53, the cutout portions 56 and the teeth 54 are alternately arranged side by side in the web width direction. Therefore, in the CNT net 33 drawn out by the scraping portion 5, at a position corresponding to the tooth 54, A small gap is formed in the web width direction. That is, in the CNT net 33 extracted by the scraping part 5, the part (partial defect) where CNT does not exist locally mostly exists in the web width direction.

As shown in FIG. 3, the take-up / extraction section 6 includes a take-up sliding section 61 and a take-up roller (roller, second member) 62.

The take-up slide portion 61 is configured to be slidably moved in a direction parallel to the longitudinal direction of the base member 20 through a slide mechanism (not shown). Although not shown, a suitable actuator (winding slide driving section) including an electric motor or the like is provided for sliding movement of the winding slide section 61. Thereby, the take-up / extraction part 6 can approach or separate from the board | substrate support part 4.

The take-up slide portion 61 is a path for the CNT net 33 drawn out from the substrate support portion 4 and is arranged on one side in the web width direction. The take-up slide portion 61 is provided on the downstream side of the substrate support portion 4 in the extraction direction.

The take-up slide portion 61 can be changed in height by a lifting mechanism (not shown). Accordingly, the take-up and withdrawal unit 6 can be retracted to a lower position so as not to interfere with the operation of the scraping unit 5 or the collecting unit 7.

The take-up roller 62 is formed in a cylindrical shape and is rotatably supported by the take-up sliding portion 61. The take-up roller 62 is arranged such that its axis is parallel to the web width direction. The length in the axial direction of the take-up roller 62 is a length including the tooth row portion 55 of the comb-shaped tooth member 53. Accordingly, the CNT net 33 drawn out by the comb-shaped tooth member 53 can be appropriately received by the take-up roller 62.

In order to rotate the winding roller 62, an electric motor (winding driving section) 63 is attached to the winding sliding section 61. The electric motor 63 is a motor that can be driven in both directions. In a state where the CNT net 33 is wound around the outer peripheral surface of the take-up roller 62, the CNT net 33 can be pulled out from the take-up roller 62 by rotating the take-up roller 62 by the electric motor 63.

The collecting section 7 includes a suction sliding section 71 and an air suction tool (suction device) 72.

The suction sliding part 71 is configured to be slidably movable in a direction parallel to the longitudinal direction of the base member 20 through a sliding mechanism (not shown). Although not shown, a suitable actuator (suction slide driving section) including an electric motor or the like is provided for slidingly moving the suction sliding section 71. Thereby, the collecting portion 7 can be approached or separated from the substrate supporting portion 4.

The air suction tool 72 is fixed to a suitable position of the suction sliding section 71 at substantially the same height as the CNT substrate 3 supported by the substrate support section 4. A suction port 72 a is formed in the air suction member 72. The suction opening 72a is arranged near the center of the web width direction of the CNT net 33 that is drawn out from the substrate support portion 4 by the take-up portion 6 when the air suction member 72 approaches the substrate support portion 4 together with the suction slide portion 71. .

The air suction member 72 generates a negative pressure by a suitable method (for example, by supplying compressed air to an ejector), and a suction flow can be generated at the suction port 72a. The air suction member 72 draws the CNT net 33 drawn out by the take-out unit 6 toward the inside by the suction flow generated at the suction port 72a, so that the CNT net 33 can be gathered into a yarn-like CNT from the width direction.部 34。 34. The suction flow generated by the air suction member 72 may include a revolving component.

Next, the extraction end preparation operation performed by the CNT substrate extraction end preparation device 2 will be described in detail with reference to the drawings.

After the CNT substrate 3 to be prepared is held by the substrate support portion 4, the scraping portion 5 is moved close to the substrate support portion 4 by slidingly moving the base portion 51, and is in an operating position that does not retreat upward. In the state shown in FIG. 5, the scraping arm 52 is rotated by the CNT array 32 whose top end of the comb-shaped tooth member 53 is inserted into the surface of the substrate support portion 4 from above.

In this state, as shown in FIG. 6, the base portion 51 of the scraping portion 5 slides away from the substrate support portion 4. As a result, the CNT array 32 is scraped by the dentition portion 55 at the front end of the comb-shaped tooth member 53, and the CNT net 33 is extracted from the CNT array 32 (first extraction process). At this time, the take-up roller 62 of the take-up / extraction section 6 is retracted toward a lower position.

Thereafter, the take-up roller 62 of the take-up / extraction section 6 rises in a state where the rotation is stopped, and contacts the CNT net 33 stretched between the CNT substrate 3 and the comb-shaped tooth member 53 from below. Thereafter, the scraping arm 52 of the scraping part 5 is rotated until it reaches the position shown by the lock line in FIG. 6. As a result, the CNT net 33 is cut between the take-up roller 62 and the comb-shaped tooth member 53 by tearing.

However, the CNT net is wound on at least a part of the outer peripheral surface of the take-up roller 62 in advance. Accordingly, the CNT net 33 can be easily attached to the upper portion of the take-up roller 62 by an intermolecular force (adhesive force). Therefore, the CNT net 33 can be received from the scraping part 5 toward the take-up and drawing part 6. Prior entanglement of the CNT net can be achieved by directly leaving the CNT net attached in one previous operation.

After the cutting of the CNT mesh 33 caused by the rotation of the scraping arm 52 is completed, the take-up roller 62 pulls the CNT mesh 33 contacted from the upper part from the CNT substrate 3 toward the direction substantially tangent as shown in FIG. The take-up direction starts to rotate. Hereinafter, the rotation of the take-up roller 62 in this direction is referred to as a normal rotation.

The take-out unit 6 slides the take-up roller 62 slightly away from the substrate support portion 4 as shown in FIG. 8 while continuing to rotate the take-up roller 62.

The CNT net 33 is further extracted from the CNT substrate 3 by the positive rotation of the take-up roller 62 (second extraction process). As described above, in the first CNT net 33 scraped by the scraping part 5, many defects in the web width direction are present. Defects may occur at the ends in the width direction of the CNT net 33 and may occur at the middle portions in the width direction. As a result of this defect, the overall width of the CNT net 33 also becomes smaller than expected. However, if the CNT net 33 is continuously pulled out from the CNT substrate 3 by the take-up roller 62, the CNTs adjacent to each other in the web width direction in the CNT array 32 are removed by intermolecular forces. Withdrawal, so the defects of the above part can gradually disappear. Finally, a CNT net 33 that is completely continuous from one end to the other end in the web width direction appears between the take-up roller 62 and the CNT substrate 3.

In this embodiment, the CNT net 33 is first drawn out by the comb-shaped tooth member 53 of the scraping-out part 5, and thereafter, the CNT net 33 is transferred by the winding roller 62 of the winding-out part 6, and the The roller 62 is wound, and the CNT net 33 is drawn out. Therefore, the CNT net 33 can be drawn out stably and long by the rotation of the take-up roller 62. As a result, the CNT mesh 33 having a sufficient length can be extracted until the defect of the part of the CNT mesh 33 disappears, and a high-quality extraction end 35 can be obtained.

And in this embodiment, the CNT array 32 is initially scraped and the CNT net 33 is pulled out by the comb-shaped tooth member 53 having the small teeth 54 which are the dentition portions 55 that are juxtaposed in parallel with a fine pitch. . Therefore, since the defects in the width direction of the CNT net 33 at the time of extraction can be reduced one by one, the above-mentioned defects can be eliminated early in the winding process by the winding roller 62, The extraction length of the CNT net 33 can be suppressed.

The CNT substrate extraction end preparation device 2 of the present embodiment further includes an inspection unit 8 that scans the presence or absence of the CNT net 33 extracted by the take-up and extraction unit 6 by scanning the web width direction.

The inspection unit 8 includes a detection sensor 81 and a reflection plate 82 as shown in FIG. 8. In FIG. 3, the detection sensor 81 and the reflection plate 82 are omitted. The detection sensor 81 and the reflection plate 82 are retracted toward the positions shown in the figure when not in use, and are moved in and out until the positions shown in FIG. 8 when in use, and can be appropriately moved.

The detection sensor 81 is a non-contact type light sensor. The detection sensor 81 is arranged above the walking path of the CNT net 33. The detection sensor 81 is supported by a suitable slide mechanism, and is configured to reciprocate in the web width direction. The detection sensor 81 detects light that is irradiated toward the reflecting plate 82 and is reflected by the reflecting plate 82.

The reflecting plate 82 is a white plate-like member that is elongated in the width direction of the mesh. The reflecting plate 82 is disposed to face the detection sensor 81 with the CNT net 33 interposed therebetween.

When the CNT net 33 is present between the detection sensor 81 and the reflection plate 82, the light is blocked, so the intensity of the light detected by the detection sensor 81 becomes small. Thereby, the presence or absence of the CNT net 33 can be detected.

The CNT substrate extraction end preparation device 2 is a computer including a control unit (not shown). The computer is a variety of actuators (including actuators that reciprocate the detection sensor 81) that control the operation of the scraping section 5, the take-out section 6, the collecting section 7, and the inspection section 8. . The detection sensor 81 is electrically connected to this computer.

The computer continuously obtains the detection result of the detection sensor 81 while reciprocating the detection sensor 81 from the mesh width direction by a predetermined stroke, and thereby obtains the CNT mesh 33 in the mesh width direction. With or without distribution. The computer continues until the predetermined standard is satisfied (in this embodiment, the defective portion does not exist within a predetermined width of the CNT net 33): the winding of the CNT net 33 by the take-up roller 62, And the inspection by the inspection section 8. This implements the inspection process.

As a result of the inspection, if the above-mentioned criterion is satisfied, the rotation of the take-up roller 62 is stopped. Thereafter, in a state in which the rotation of the take-up roller 62 is stopped, the take-up and withdrawal section 6 slides further away from the substrate support section 4 as shown by the lock line in FIG. 9. With this, the CNT net 33 is further extracted from the CNT substrate 3.

Thereafter, the take-up / extraction section 6 lowers the take-up roller 62 slightly, and then slides the take-up roller 62 in a direction approaching the substrate support section 4. Since the take-up roller 62 is stopped in this process, slack occurs in the CNT net 33 between the take-up roller 62 and the CNT substrate 3.

Almost interlocking with this, as shown in FIG. 10, the collecting portion 7 slides the air suction member 72 so as to approach the substrate supporting portion 4. Then, a suction flow is generated at the suction port 72 a of the air suction member 72, and the CNT net 33 between the winding roller 62 and the CNT substrate 3 is sucked and captured. At the same time as the suction of the CNT net 33 by the air suction member 72, the take-up roller 62 is reversely rotated at high speed. As a result, the CNT net 33 is cut between the air suction member 72 and the take-up roller 62 by tearing.

The slack portion of the CNT net 33 also includes the end portion formed by the above-mentioned cutting and is sucked into the suction port 72a. The CNT net 33 sucked into the suction port 72a is aggregated in a shortened manner in the width direction and aggregates into a yarn-shaped CNT portion 34 (integration process).

After that, the collecting section 7 stops the suction flow, and slides the air suction tool 72 in a direction away from the substrate support section 4 as shown in FIG. 11. As a result, the yarn-shaped CNT portion 34 is exposed from the suction port 72a.

In this way, the CNT substrate extraction end preparation device 2 extracts a CNT net 33 having a predetermined width from the CNT substrate 3, and forms a yarn-shaped CNT portion 34 at the tip thereof, which can be easily captured. The CNT substrate 3a having the extraction end 35 can be prepared.

As described above, the CNT substrate extraction end preparation device 2 of the present embodiment includes the substrate support portion 4, the scraping portion 5, the winding extraction portion 6, and the collection portion 7. The substrate support portion 4 supports the CNT substrate 3 on which the CNTs are formed. The scraping part 5 is in contact with the CNT formed on the CNT substrate 3, and pulls out the CNT net 33 from the CNT substrate 3. The take-up / extraction unit 6 collects the CNT net 33 which is extracted by the scraping unit 5 and extracts the CNT net 33 from the CNT substrate 3. The collecting unit 7 collects the CNT net 33 between the CNT substrate 3 and the take-up / extract unit 6 in the web width direction.

Thereby, the CNT net 33 can be reliably pulled out from the CNT substrate 3, and it is possible to prepare for a state in which handling in textile in the next process is easy.

In addition, the CNT substrate extraction end preparation device 2 of this embodiment is provided with an inspection unit 8 for inspecting whether or not a defect portion in which CNT does not exist exists within a predetermined width range for the CNT net 33 that is extracted by the winding extraction unit 6.

Thereby, after confirming that the CNT net 33 is reliably drawn out with a predetermined width, the CNT net 33 can be aggregated by the collection unit 7.

Further, in the CNT substrate extraction end preparation device 2 of this embodiment, the extraction unit 6 is rolled up until the inspection unit 8 determines that the defective portion does not exist within a predetermined width range, and the extraction of the CNT net 33 is continued.

That is, the CNT net 33 is initially extracted within a predetermined width range. Even if it is assumed that a defect portion where the CNT does not exist is present, by continuously extracting the defect portion, the defect portion is re-existed by the intermolecular force of the CNT. When the extracted CNT disappears. By continuously drawing out the CNT net 33 until there is no defect, the yield of inspection can be improved.

Further, in the CNT substrate extraction end preparation device 2 of the present embodiment, the scraping portion 5 is provided with a comb-shaped tooth member 53 that is in contact with the CNT.

Thereby, the CNT formed on the CNT substrate 3 can be easily captured by the comb-shaped tooth member 53 and extracted as the CNT net 33.

Further, in the CNT substrate extraction end preparation device 2 of this embodiment, the comb-shaped tooth member 53 is in contact with the CNT formed on the CNT substrate 3.

Accordingly, the carbon nanotube can be easily captured and extracted.

Further, in the CNT substrate extraction end preparation device 2 of the present embodiment, the winding extraction unit 6 includes a winding roller 62 that winds the CNT net 33.

Accordingly, by winding the CNT net 33 on the take-up roller 62, the CNT net 33 can be easily pulled out over a long distance.

Further, in the CNT substrate extraction end preparation device 2 of the present embodiment, the collection section 7 is provided with an air suction member 72 that sucks the CNT net 33.

Thereby, the CNT net 33 can be easily collected in the width direction by attracting the flow.

Although the preferred embodiment of the present invention has been described above, the above-mentioned configuration can be changed as follows, for example.

The inspection unit 8 is an inspection for omitting a defect in a portion in the width direction of the CNT net 33, and it is only necessary to check whether the CNT net 33 has a predetermined width.

The inspection unit 8 may not only check the presence or absence of the CNT net 33, but may further check the unevenness of the CNTs in the CNT net 33.

The collecting section 7 can replace the configuration in which the CNT net 33 is collected by the suction generated by the air suction member 72, and for example, the CNT net 33 is held by being pressed from both sides in the width direction of the net, and gathered in the width direction. Yes.

Instead of the comb-shaped tooth member 53, a linear extraction member (squeegee-shaped extraction member) may be used in which the tip end in contact with the CNT is continuous from one end of the width drawing the CNT net 33 across the other end. In this case, the extraction member can be easily formed.

The direction in which the CNT substrate 3 is assembled in the CNT substrate extraction end preparation device 2 and the direction in which the CNT net 33 is extracted from the CNT substrate 3 can be appropriately changed in accordance with the layout arrangement of the device. The same applies to the yarn spinning device 1.

The CNT substrate 3a having the extraction end 35 prepared by the CNT substrate extraction end preparation device 2 may be used for applications other than textiles.
