Technical Field

[0001] This invention relates to a processing method and a processing apparatus. Background Technology

[0002] For example, as shown in Patent Document 1, a printing method is known for applying ink to fabrics and the like to perform printing.

Detailed Implementation

[0017] The processing method and processing apparatus of the present invention will be described in detail below based on suitable embodiments illustrated in the accompanying drawings.

[0018] First Implementation Method

[0019] Figure 1 A simplified configuration diagram of a first embodiment of a processing apparatus for performing the processing method of the present invention.

[0020] It should be noted that, in Figure 1 (for Figures 2-7 Similarly, the upper side is referred to as "above" or "upper," and the lower side is referred to as "below" or "lower." Additionally, in... Figure 1 In the middle, the left side is the upstream side of the conveying direction of the cloth 100, and the right side is the downstream side of the conveying direction of the cloth 100.

[0021] Figure 1The processing apparatus 1 shown is an apparatus for performing the processing method of the present invention. It should be noted that "processing" or "surface treatment" in this specification refers to at least one treatment selected from bending, beating, stretching, and rubbing the fabric 100. Friction treatment is also referred to as napping treatment. Performing such treatment can improve the hand feel after printing. The processing in this embodiment mainly conforms to stretching and rubbing. Bending and beating are described in detail in the fifth embodiment.

[0022] The processing method of the present invention is applied to fabrics. The fibers constituting the fabric are not particularly limited, and examples include natural fibers such as cotton, linen, wool, and silk; synthetic fibers such as cellulose acetate, cellulose triacetate, polyamide, and polyurethane; biodegradable fibers such as polylactic acid; and blends thereof.

[0023] The fabric can also be an article obtained by processing the aforementioned fibers into textiles, woven fabrics, nonwoven fabrics, etc. Furthermore, there is no particular limitation on the basis weight of the fabric used in this embodiment; for example, it can be 1.0 oz or more and 10.0 oz or less, preferably 2.0 oz or more and 9.0 oz or less, more preferably 3.0 oz or more and 8.0 oz or less, and even more preferably 4.0 oz or more and 7.0 oz or less. As long as the basis weight of the fabric is within such a range, good recording is possible.

[0024] Examples of fabrics used in this embodiment include cloth, clothing, and other garment accessories. Examples of cloth include woven fabrics, knitted fabrics, and non-woven fabrics. Examples of clothing and other garment accessories include sewn T-shirts, handkerchiefs, headscarves, towels, tote bags, cloth bags, curtains, sheets, bedspreads, wallpaper, and other household items, as well as fabrics before and after cutting, used as parts before sewing. Examples of these forms include long, thin items rolled into a tube, items cut to a predetermined size, and items in the shape of a finished product. It should be noted that fabrics pre-treated with a treatment liquid can also be used.

[0025] As fabric, pre-dyed fabric can also be used. Examples of pre-dyed fabric dyes include water-soluble dyes such as pigments, acid dyes, and basic dyes, as well as disperse dyes and reactive dyes that also use dispersants. When using cotton fabric, reactive dyes and pigments suitable for dyeing cotton are preferred. When using pigments, it is preferable to use dyes that can handle a wider variety of fabric types. Although the hand feel of fabric dyed with pigments is reduced due to the large amount of solid components present on the fabric surface, by performing the processing method of the present invention, the hand feel can be improved and can be approximated to the original hand feel of the fabric.

[0026] like Figure 1As shown, the processing device 1 includes a conveying unit 2, a vibration application unit 3, and a control unit 4 that controls the operation of these units.

[0027] The conveying unit 2 has a first conveying unit 21 and a second conveying unit 22 for conveying fabric (hereinafter referred to as "fabric 100").

[0028] The first conveying section 21 is located upstream of the contact member 31 of the vibration application section 3 in the conveying direction of the fabric 100. The first conveying section 21 has a drive roller 211 and a driven roller 212 arranged across the fabric 100 in the thickness direction. The drive roller 211 is electrically connected to the control section 4 via a motor (not shown). The control section 4 can adjust the rotational speed, i.e., the conveying speed, of the drive roller 211 by controlling the energizing conditions of the motor.

[0029] The driven roller 212 contacts and rotates with the fabric 100 that is being conveyed by the rotation of the driving roller 211. This first conveying section 21 enables the fabric 100 to be stably conveyed from the upstream side to the downstream side.

[0030] The second conveying section 22 is located downstream of the contact member 31 in the conveying direction of the fabric 100. The second conveying section 22 has a drive roller 221 and a driven roller 222 arranged across the fabric 100 in the thickness direction. The drive roller 221 is electrically connected to the control unit 4 via a motor (not shown). The control unit 4 can adjust the rotational speed, i.e., the conveying speed, of the drive roller 221 by controlling the energizing conditions of the motor.

[0031] The driven roller 222 contacts and rotates with the fabric 100 that is being conveyed by the rotation of the driving roller 221. This second conveying section 22 enables the fabric 100 to be conveyed stably from the upstream side to the downstream side.

[0032] In addition, the tension of the conveyed fabric 100 can be adjusted by adjusting the rotation speed of the drive roller 211 and drive roller 221.

[0033] It should be noted that the shaft torque can be monitored and adjusted by using the rotating shafts connected to the drive rollers 211 and 221 via a converter, thereby adjusting the tension in the conveying direction of the fabric 100. By adjusting the tension in the conveying direction of the fabric 100 and setting it to an appropriate value, the vibrating fabric 100 can resonate. Therefore, the hand feel quality of the fabric 100 can be effectively improved.

[0034] Furthermore, the tension in the direction intersecting the conveying direction of the fabric 100, i.e., the width direction of the fabric 100, can be adjusted by using rollers with an inverted crown shape formed by concave processing, rollers with a spiral structure arranged symmetrically from the center, and extended rollers that convey fabric in a zigzag shape towards the outside. By adjusting the tension in the width direction of the fabric 100 and setting it to an appropriate value, the vibrating fabric 100 can resonate. Therefore, the hand feel quality of the fabric 100 can be effectively improved.

[0035] The vibration application unit 3 has two contacting parts 31 and two vibration generating sources 32. The vibration application unit 3 has the function of applying vibration to the fabric 100 during transport. This allows the surface of the fabric 100 to be treated. The treatment in this embodiment mainly refers to the treatment that causes stretching and friction phenomena.

[0036] Stretching refers to the following treatment.

[0037] While applying a relatively large tension to the fabric 100, the back of the fabric 100 is in contact with the protrusion 352 of the contact member 35, and a vibration with a small period and a large amplitude is applied to the contact member 35. At this time, due to the influence of the relatively large tension acting on the fabric 100, the fabric 100 will repeatedly stretch and relax in accordance with the phase of the protrusion 352. By repeatedly stretching and relaxing the fiber bundles constituting the fabric 100 with the protrusion 352 as the fulcrum, a small embossed residual strain can be formed in the non-stretchable fabric 100. The small embossed residual strain has the effect of improving the fluffiness in the non-stretchable fabric and can effectively improve the hand feel of the fabric. It should be noted that the protrusion 352 is preferably a small area that is the same as or less than 10 times the texture period of the fibers of the fabric 100, and more preferably has a curvature shape and planar shape that is difficult to generate stress concentration so as not to penetrate the fibers of the fabric or cut the fibers of the fabric 100.

[0038] In addition, friction refers to the following treatment.

[0039] The following process is referred to as friction, which involves applying vibration to the vibration transmission member while a predetermined tension is applied to the fabric 100 and the surface of the fabric 100 is in contact with the protrusion 352 of the contact member 35, thereby causing the fibers of the fabric 100 to become fuzzy using the protrusion 352. A good hand feel can be obtained by fuzzing the fibers.

[0040] The protrusion 352 is preferably brush-shaped with a small outer diameter that is the same as or smaller than the weave period of the fibers of the fabric 100. More preferably, the brush-shaped protrusion 352 has a moderate Young's modulus that makes it difficult for the fibers of the fabric 100 to penetrate through it. Thus, the protrusion 352 can maintain contact with the fabric 100 without penetrating through it and can effectively transmit vibrational energy.

[0041] In this embodiment, the abutting members 31 are arranged on both sides of the conveyed fabric 100 in the thickness direction. Since all abutting members 31 are identical except for their arrangement, a representative description of one abutting member 31 will be given below.

[0042] In this embodiment, the abutting member 31 is constructed of a brush and has a base 311 and a plurality of protrusions 312 extending from the base 311. The base 311 in this embodiment is constructed of a cylindrical component. Furthermore, the base 311 is connected to a motor (not shown), and the base 311 is abutted by the transmission of the rotational force of the motor. Figure 1 Rotate in the direction of the arrow in the image.

[0043] In addition, it is located closer to than cloth 100. Figure 1 The base 311 at the top of the middle is located closer to the cloth 100. Figure 1 The drive rollers 211 and 221, located above the fabric 100, rotate in opposite directions. Figure 1 The base 311 at the bottom of the middle is located closer to the cloth 100. Figure 1 The driven rollers 212 and 222 at the bottom rotate in opposite directions. With this configuration, the fabric 100 can be processed more efficiently.

[0044] The protrusions 312 are each in the form of an elastic thread or rod. The lengths of the protrusions 312 can be the same or different. There are no particular limitations on the material used to construct the protrusions 312; various resin materials and various metal materials can be used, for example. From the viewpoint of achieving good napping, metal materials are preferred. There are no particular limitations on the metal material; brass, steel, stainless steel, etc., can be used appropriately. When steel is used, napping can be performed more reliably. When the fabric 100 is colored with pigment, using brass allows for napping while suppressing damage to the colored areas.

[0045] Specifically, when the area of ​​the portion on the surface of the base 311 where the protrusion 312 is provided is set as S1, and the area of ​​the portion where the protrusion 312 is not provided is set as S2, it is preferable that S2 / S1 is 1 or more and 100 or less, and more preferably 1.2 or more and 90 or less. As a result, the surface treatment of the fabric 100 can be performed more effectively.

[0046] The average outer diameter of the protrusion 312 is preferably 0.05 mm or more and 5 mm or less, more preferably 0.1 mm or more and 4 mm or less, and even more preferably 0.1 mm or more and 0.4 mm or less. This ensures sufficient contact area between the protrusion 312 and the fabric 100, allowing for more effective surface treatment of the fabric 100. In particular, it facilitates the achievement of a napped effect on the fabric 100, resulting in a pleasant hand feel.

[0047] Furthermore, the Young's modulus of the protrusion 312 is preferably above 100E / GPa and below 250E / GPa, more preferably above 120E / GPa and below 230E / GPa. This ensures that the Young's modulus of the protrusion 312 is sufficient, allowing for more effective surface treatment of the fabric 100 with appropriate elasticity. In particular, it facilitates the achievement of a napped effect on the fabric 100, resulting in a pleasant hand feel.

[0048] Furthermore, preferably, the protrusion 352 moves in the conveying direction of the fabric 100 at a fixed or different conveying speed, i.e., it has a speed difference relative to the fabric 100. Through repeated frictional action between the protrusion 352 and the fabric 100 at the contact portion, the protrusion 352 promotes the disorder of the arrangement between parallel fibers, the misalignment of the crossing positions of intersecting fiber bundles, and the partial destruction of the fiber structure. In particular, by setting a relatively large average outer diameter and Young's modulus of the protrusion 352, the effect of promoting the partial destruction of the fiber structure is increased. By repeatedly partially cutting the fibers and lifting the cut fibers, a napped state can be formed on the surface of the fabric 100, which can effectively improve the hand feel of the fabric.

[0049] The vibration source 32 has an oscillator 321 (not shown) that generates vibration. The oscillator 321 is electrically connected to the control unit 4. Furthermore, the oscillation of the oscillator 321 is controlled by the control unit 4 controlling the energizing conditions of the oscillator 321.

[0050] In addition, the vibration source 32 has a vibration transmission component 322. The vibration transmission component 322 is made of a rigid body and connects the housing containing the vibrator 321 to the base 311 of the contact component 31, and transmits the vibration generated by the vibrator 321 to the contact component 31. Thus, vibration can be transmitted to the fabric 100 via the contact component 31.

[0051] The vibration amplitude is preferably 0.1 mm or more and 100 mm or less, more preferably 0.2 mm or more and 80 mm. This allows for more effective surface treatment of the fabric 100.

[0052] Furthermore, the vibration frequency is preferably 10 Hz or higher and 10,000 Hz or lower, more preferably 100 Hz or higher and 2,000 Hz or lower. This allows for more effective surface treatment of the fabric 100.

[0053] Furthermore, the vibration transmitted to the fabric 100 preferably includes a component along the thickness direction of the fabric 100 during transport. This allows for more efficient surface treatment.

[0054] Furthermore, the vibration transmitted to the fabric 100 preferably includes a component along the conveying direction of the fabric 100 during conveying. This allows for more efficient surface treatment.

[0055] Furthermore, the vibration transmitted to the fabric 100 preferably includes a component in the direction intersecting with the conveying direction of the fabric 100, that is, along the width direction of the fabric 100 being conveyed. This allows for better surface treatment.

[0056] The control unit 4 independently controls the operation of each component, including the conveying unit 2 and the vibration generator 32. The control unit 4 includes, for example, a CPU as a processor, RAM, and ROM storing programs. Furthermore, the functions of the control unit 4 can be implemented, for example, by executing various programs using the CPU.

[0057] In order to improve the hand feel of the printed fabric 100, a napping treatment is effective, for example. The treatment method of the present invention can restore the hand feel damaged by solid components adhering to the fabric during printing. Conventionally, this treatment involves heat treatment and chemical treatment. Alternatively, it is also possible to improve the hand feel by napping the fabric with a brush, either by pushing or rubbing. However, such methods may result in insufficient napping, failing to improve the hand feel. Therefore, the processing apparatus 1 of the present invention is configured as follows.

[0058] The processing apparatus 1 includes: a conveying unit 2 for conveying fabric 100; and a vibration applying unit 3, the vibration applying unit 3 having an abutment member 31 having a base 311 and a plurality of protrusions 312 and a vibration generating source 32 for applying vibration to the abutment member 31. The protrusions 312 protrude from the base 311 and abut against the fabric 100 conveyed by the conveying unit 2. This allows for a good surface treatment of the fabric 100. Therefore, the hand feel of the fabric 100 can be improved. In particular, it is preferred in terms of improving the hand feel of the fabric 100 after printing. Especially, compared to methods that only use abutment members such as brushes to process the fabric 100, applying vibration can result in good napping and improve the hand feel.

[0059] Furthermore, it is preferable that the contact member 31 is a brush with a protrusion 312 in the shape of a line. This allows for more efficient surface treatment of the fabric 100. Also, the contact member 31 can be obtained more cost-effectively. In addition, since the protrusion 312 is positioned on a roller and rotates to contact the fabric 100, it results in good napping and improved hand feel.

[0060] Furthermore, the processing method of the present invention includes a step of preparing the aforementioned vibration application part 3, and a vibration application step of applying vibration to the fabric 100 using the vibration application part 3. That is, the processing method of the present invention includes a step of preparing a vibration application part 3 having a contact member 31 and a vibration generating source 32 that applies vibration to the contact member 31, and a vibration application step. The contact member 31 has a base 311 and a plurality of protrusions 312 protruding from the base 311 and contacting the fabric 100. In the vibration application step, while the protrusions 312 are in contact with the fabric 100, the vibration generating source 32 is driven to vibrate the protrusions 312, thereby applying vibration to the fabric 100 by means of the protrusions 312. This allows for proper processing of the fabric 100. Therefore, the hand feel of the fabric 100 can be improved. In particular, it is preferable to improve the hand feel of the fabric 100 after printing. In particular, compared with the method of treating fabric 100 by simply using abutting parts such as brushes, applying vibration can make the napping better and improve the hand feel.

[0061] Furthermore, it is preferable that, during the vibration application process, the fabric 100 is vibrated while being conveyed. This allows for highly efficient surface treatment of the fabric.

[0062] Furthermore, a conveying speed of 1 cm / s or more and 50 cm / s or less is preferred, and 2 cm / s or more and 20 cm / s or less is more preferable. This allows for more reliable surface treatment while significantly improving processing efficiency.

[0063] Furthermore, it is preferable that the rotational speed of the contacting component 31 is between 1 rpm and 100 rpm, more preferably between 5 rpm and 50 rpm. This allows for more reliable processing while significantly improving processing efficiency.

[0064] Furthermore, preferably, a pair of abutting members 31 are provided in the conveying path of the fabric 100 across the thickness direction of the fabric 100, and vibration is applied from both sides of the fabric 100 in the thickness direction using the pair of abutting members 31 during the vibration application process. This allows for surface treatment of both sides of the fabric 100.

[0065] It should be noted that this configuration is not limited to this, and one of the pair of abutting members 31 may be omitted. Alternatively, the abutting member 31 may be positioned either close to or far from the fabric 100 being transported. In this case, the degree of surface treatment can be adjusted.

[0066] In addition, in this embodiment, the abutting member 31 is composed of a brush with the protrusion 312 in the shape of a line. However, in this invention, it is not limited to this, and the protrusion 312 may also be in the shape of a rod made of a rigid body.

[0067] Second Implementation Method

[0068] Figure 2 A simplified configuration diagram of a second embodiment of a processing apparatus for performing the processing method of the present invention.

[0069] The second embodiment of the processing method and processing apparatus of the present invention will be described below with reference to these figures, focusing on the differences from the aforementioned embodiments, and the same matters will be omitted from the description.

[0070] like Figure 2 As shown, in this embodiment, a pair of abutting members 31 are staggered along the conveying direction of the fabric 100. Specifically, when viewed from above on the fabric 100 being conveyed, each base 311 is positioned in a non-overlapping location.

[0071] With this configuration, the positions on the upper and lower surfaces of the fabric 100 from which vibrations are directly transmitted from the contact member 31 can be staggered. Therefore, even if both sides of the fabric 100 are treated, damage caused by vibrations applied to the fabric 100 can be reduced.

[0072] Third Implementation Method

[0073] Figure 3 A simplified configuration diagram of a third embodiment of a processing apparatus for performing the processing method of the present invention.

[0074] The third embodiment of the processing method and processing apparatus of the present invention will be described below with reference to these figures, focusing on the differences from the aforementioned embodiments, and the same matters will be omitted from the description.

[0075] like Figure 3 As shown, in this embodiment, an abutting member 31 is provided on the upper side of the fabric 100 being transported. In this embodiment, the vibration source 33 is disposed on the opposite side of the abutting member 31, across the fabric 100 being transported.

[0076] Furthermore, a vibration transmission component 34 is provided between the fabric 100 and the vibration source 33 to transmit the vibration generated by the vibration source 33 to the fabric 100. The vibration transmission component 34 is made of an elastomer, for example, made of various resin materials, various rubber materials, etc. As a result, damage to the fabric 100 caused by vibration can be reduced, and good surface treatment can be achieved.

[0077] Fourth Implementation Method

[0078] Figure 4 A simplified configuration diagram of a fourth embodiment of a processing apparatus for performing the processing method of the present invention.

[0079] The fourth embodiment of the processing method and processing apparatus of the present invention will be described below with reference to these figures, focusing on the differences from the aforementioned embodiments, and the same matters will be omitted from the description.

[0080] like Figure 4 As shown, the abutting member 35 in this embodiment has a flat base 351 and a plurality of protrusions 352 protruding from the base 351. The abutting member 35 is configured such that the front ends of the protrusions 352 contact the lower surface of the fabric 100. In addition, the lengths of each protrusion 352 are approximately the same.

[0081] According to this embodiment, it is easy to ensure that the contact area and time between the protrusion 352 and the fabric 100 are sufficient. Therefore, the surface treatment of the fabric 100 can be performed more reliably.

[0082] Fifth Implementation Method

[0083] Figure 5 A simplified configuration diagram of a fifth embodiment of a processing apparatus for performing the processing method of the present invention.

[0084] The fifth embodiment of the processing method and processing apparatus of the present invention will be described below with reference to these figures, focusing on the differences from the aforementioned embodiments; similar points will be omitted from the description. It should be noted that in... Figure 5 The diagram of the vibration source is omitted.

[0085] like Figure 5 As shown, the abutting member 36 in this embodiment has a base 361 and a plurality of protrusions 362 protruding from the base 361. A pair of abutting members 36 are provided across the fabric 100 being conveyed. The protrusions 362 are cylindrical or... Figure 7 It is composed of a spherical rigid body or a rigid elastic body as shown.

[0086] Furthermore, when viewed from above the fabric 100, the protrusions 362 located on opposite sides of the fabric 100 can be arranged in an alternating manner to prevent them from interfering with each other, for example. Therefore, even if the amplitude of the vibration is set relatively large, interference between the protrusions 362 can be prevented.

[0087] When the elements are staggered, a high bending effect can be achieved.

[0088] Furthermore, when viewed from above, the protrusions 362 on opposite sides of the fabric 100 can be seen without being separated. Under such conditions, a high-quality percussion effect can be achieved.

[0089] According to the processing method involved in this fifth embodiment, the fabric 100 can be bent and beaten, and the fabric 100 can be properly processed.

[0090] Bending refers to the following treatment.

[0091] While applying a predetermined tension to the fabric 100, and with the back of the fabric in contact with the protrusion 362 of the contact member 35, once vibration is applied to the contact member 36, the deformation action of the fiber bending angle will be repeated with the protrusion 362 as the fulcrum, thereby promoting the relaxation of the association force between parallel fibers, the release of the junction of the intersecting fiber bundles, and the partial destruction of the fiber structure, thereby reducing the rigidity of the fabric 100.

[0092] Preferably, when vibration is applied, the contact area between the protrusion 362 and the fabric 100 is reduced, and the bending angle relative to the fulcrum formed when vibration is applied is increased. That is, it is preferable to increase the distance between the fulcrums, so that the amplitude formed by the deformation of the fabric 100 when vibration is applied to the fabric 100 is increased. As a result, since the amplitude of the fabric formed by the transmitted vibration energy is increased and the bending angle of the fibers is increased, the rigidity of the fabric 100 can be further reduced, resulting in a better hand feel.

[0093] Preferably, when applying vibration, a vibration period / amplitude and tension corresponding to the natural vibration coefficient of the fabric 100 are applied. This causes the fabric 100 to enter a resonant state. Therefore, effective bending actions can be repeated with relatively small vibrational energy, effectively improving the fabric's hand feel.

[0094] Additionally, "tapping" refers to the following treatment.

[0095] While applying a relatively small tension to the fabric 100, vibrations are applied to the abutting member 36 from both sides of the fabric 100 while the abutting member 36 is engaged. Vibrations are applied to the protrusions 362 in a manner that causes them to cross or collide with each other vertically from the surface and back of the fabric 100. By repeatedly colliding a portion of the fabric 100 with the protrusions 362 or with the base 361 of the abutting member 36, a striking effect is achieved. This repeatedly compresses and restores the fiber bundles. At this time, the disordered arrangement of parallel fibers, the misalignment of the crossing positions of intersecting fiber bundles, and the partial structural damage of fibers lead to the widening of gaps between fibers, the increased distance between fiber bundles, and the increased napping caused by partial fiber cutting, thereby increasing the fluffiness of the fabric and improving its hand feel.

[0096] Furthermore, when the protrusions 362 are arranged in an alternating manner so that they do not contact each other, the fabric 100 can simultaneously repeat a relatively weak tapping action formed by the collision with the base 361 of the abutting member 36 and a relatively weak bending action with the protrusions 362 as fulcrums, which can efficiently improve the feel of the fabric.

[0097] It should be noted that when the protrusions 352 are configured to cause the fabric 100 to repeatedly fall and bounce due to gravity, the fabric 100 is subjected to strong concentrated stress in a very short time through the collision between the protrusions 352 on both sides, so as to repeatedly compress and recover the fiber bundles. At this time, the disordered arrangement between parallel fibers, the misalignment of the crossing positions of intersecting fiber bundles, the partial destruction of fiber structure, the expansion of gaps between fibers, the increase in distance between fiber bundles, the increase in napping formed by the cutting of part of the fiber, and the increase in the fluffiness of the fabric can effectively improve the hand feel of the fabric.

[0098] In addition, such as Figure 6 As shown, the fabric 100 can also be conveyed and processed while being held between two sides by the sheet-like intermediate member 200. This prevents or suppresses contact marks between the fabric 100 and the protrusion 352. The sheet-like intermediate member 200 can be the same material as the fabric 100, but a soft, releasable sheet is preferred.

[0099] Furthermore, it is preferable that the front end of the protrusion 362 is rounded. This more effectively prevents the protrusion 362 from damaging the fabric 100. It should be noted that the front end of the protrusion 362 can also be sharp. It should also be noted that the curvature of the front end of the protrusion 362 is preferably, for example, a radius of curvature of 1 mm or more and 100 mm or less, more preferably 3 mm or more and 80 mm or less. This prevents processing marks caused by the protrusion 362 colliding with the fabric surface, even if printing has been done on the fabric surface.

[0100] Preferably, the length of the protrusion 362 (the length from the base 361 to the front end of the protrusion 362) is 1 mm or more and 100 mm or less, more preferably 10 mm or more and 50 mm or less. Therefore, when vibration is applied with the protrusion 362 intersecting each other in the vertical direction of the surface and the vertical direction of the back of the fabric 100, the striking effect achieved by the upper and lower protrusions can be improved.

[0101] The processing method and processing apparatus of the present invention have been described above with reference to the illustrated embodiments, but the present invention is not limited thereto. Furthermore, each step and part of the processing method and processing apparatus can be replaced with any step or structure that can perform the same function. Additionally, any steps or structures may be added.
