[0002] For example, as shown in Patent Document 1, there are known printing methods that involve printing ink onto fabrics. The printed fabric can easily deteriorate its original texture and quality, necessitating improvements. Texture refers to the tactile feel, skin feel, and other physical sensations.

[0003] In the printing method described in Patent Document 1, an attempt was made to improve the texture of the printed fabric by heat-treating a specific portion of the fabric before printing. Furthermore, the method is not limited to such heat treatment; physical treatments such as brushing to roughen the surface of the fabric are also considered.

[0027] The processing method and processing apparatus of the present invention will now be described in detail with reference to the preferred embodiments shown in the accompanying drawings.

[0028] <First Implementation Method>

[0029] Figure 1 This is a schematic configuration diagram of a first embodiment of a processing apparatus for performing the processing method of the present invention. Figure 2 yes Figure 1 An enlarged longitudinal cross-sectional view of the liquid jet section of the processing device shown. Figure 3 yes Figure 1 A cross-sectional side view of the vibration imparting part of the processing device shown.

[0030] In addition, Figures 1-4 In Chinese, the upper side is referred to as "above" or "upper," and the lower side is referred to as "below" or "lower." Furthermore, 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.

[0031] The processing method of the present invention is composed of Figure 1 The processing apparatus 1 shown is used for execution. The processing method of the present invention is performed, for example, as a pretreatment for a printing process in which fabric 100 is printed, but is not limited thereto.

[0032] The processing method of this invention is applied to fabrics. The fibers constituting the fabric are not particularly limited; examples include natural fibers such as cotton, linen, wool, and silk; synthetic fibers such as polypropylene, polyester, acetate, triacetate, polyamide, and polyurethane; biodegradable fibers such as polylactic acid; and blends thereof. From the viewpoint of easily obtaining a good texture, cotton or polyester fabrics are preferred.

[0033] The fabric can be made from the aforementioned fibers into any form, such as woven fabric, knitted fabric, or nonwoven fabric. Furthermore, the weight per unit area of ​​the fabric used in this embodiment is not particularly limited; for example, it can be 1.0 oz to 10.0 oz, preferably 2.0 oz to 9.0 oz, more preferably 3.0 oz to 8.0 oz, and even more preferably 4.0 oz to 7.0 oz. If the weight per unit area of ​​the fabric is within this range, good recording, i.e., printing, is possible.

[0034] Examples of fabrics used in this embodiment include cloth and clothing or other accessories. Cloths include textiles, knitted fabrics, and non-woven fabrics. Clothing or other accessories include sewn T-shirts, handkerchiefs, headscarves, towels, tote bags, cloth bags, curtains, sheets, bedspreads, wallpaper, and other interior decorations, as well as fabrics before and after cutting, used as parts before sewing. Their forms include long strips of fabric rolled up, fabrics cut to specified sizes, and fabrics shaped like products. Additionally, fabrics pre-treated with a treatment solution can be used.

[0035] As fabric, pre-dyed fabric can 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 with dispersants and reactive dyes. In the case of cotton fabric, reactive dyes or pigments suitable for cotton dyeing are preferred. When using pigments, it is preferable to be able to handle the dyeing of a wider variety of fabrics. Fabric dyed with pigments tends to have a lower texture due to the presence of a large amount of solid components on the surface; by performing the processing method of the present invention, the texture can be improved, approaching the original texture of the fabric.

[0036] like Figure 1 As shown, the processing apparatus 1 includes: a conveying unit 2, a liquid spraying unit 4, a liquid removal unit 5, a vibration imparting unit 3, and a control unit 6 that controls the operation of the conveying unit 2, the liquid spraying unit 4, the liquid removal unit 5, and the vibration imparting unit 3. In this processing apparatus 1, a continuous strip of fabric 100 is processed as a fabric.

[0037] The conveying unit 2 is a device for conveying the fabric 100, and includes: an extraction unit 21 located upstream in the conveying direction for unwinding the fabric 100 that is wound into a roll; a winding unit 22 located downstream in the conveying direction for winding the processed fabric 100 into a roll; an intermediate roller 23; an intermediate roller 24; an intermediate roller 25; and an intermediate roller 26.

[0038] The extraction section 21 has a roller 211 on which the fabric 100 is wound and a first electric motor (not shown) that imparts rotational force to the roller 211. Figure 1 In the middle, the cloth 100 wound on the roller 211 is pulled out by rotating the roller 211 clockwise.

[0039] The winding section 22 has a roller 221 on which the fabric 100 is wound and a second motor (not shown) that imparts rotational force to the roller 221. Figure 1 In the middle, by rotating the roller 221 clockwise, the cloth 100 can be rolled up and wound into a roller shape.

[0040] The control unit 6 can adjust the rotational speed, i.e. the conveying speed, of rollers 211 and 221 by controlling the conditions for energizing the first motor and the second motor. In addition, the control unit 6 can appropriately set the tension of the fabric 100 during conveying by controlling the rotational speed of the first motor and the rotational speed of the second motor, i.e., adjusting the speed difference between the unwinding speed and the winding speed of the fabric 100.

[0041] Intermediate rollers 23, 24, 25, and 26 are disposed between the extraction section 21 and the winding section 22 on the conveying path of the fabric 100. From the extraction section 21 towards the winding section 22, i.e., from the upstream side of the conveying direction towards the downstream side of the conveying direction, the intermediate rollers 23, 24, 25, and 26 are sequentially arranged on the conveying path of the fabric 100. The intermediate rollers 23, 24, 25, and 26 function as conveying rollers that transport the fabric 100 from the upstream side to the downstream side of the conveying path.

[0042] The intermediate roller 24 also serves as part of the liquid spraying section 4, acting as a support roller for supporting the fabric 100 to which the sprayed liquid is placed. The intermediate roller 25 also serves as part of the liquid removal section 5, and also functions as a drying heater. That is, the intermediate roller 25 is a heating roller for heating the fabric 100.

[0043] Intermediate rollers 23 and 25 are in contact with the lower surface of the fabric 100 being conveyed, while intermediate rollers 24 and 26 are in contact with the upper surface of the fabric 100 being conveyed.

[0044] Intermediate rollers 23, 24, 25 and 26 can be either self-rotating drive rollers or self-driven driven rollers without rotational drive force.

[0045] When intermediate rollers 23, 24, 25 and 26 are active rollers, each roller has a built-in or connected motor (not shown), and the control unit 6 controls the conditions for energizing each motor.

[0046] With such a conveying unit 2, the fabric 100 can be stably conveyed from the upstream side to the downstream side of the conveying path at the desired speed.

[0047] Furthermore, the tension of the fabric 100 in the conveying direction can be adjusted by monitoring and adjusting the shaft torque of the drive rollers such as roller 211 and roller 221. By adjusting the tension of the fabric 100 in the conveying direction and setting it to an appropriate value, the processing described later can be performed further well and appropriately, and the texture quality of the fabric 100 can be effectively improved.

[0048] Furthermore, regarding the adjustment of tension in the direction intersecting with the conveying direction of the fabric 100, i.e., in the width direction of the fabric 100, the intermediate rollers 23 to 26 can be adjusted using rollers with a concave, downward-pointing inverted crown shape, rollers with a spiral structure arranged symmetrically from the center, and widening rollers that convey fabric in a shape bent outwards. By adjusting the tension in the width direction of the fabric 100 and setting it to an appropriate value, the processing described later can be performed further well and appropriately, effectively improving the texture and quality of the fabric 100.

[0049] like Figure 1 As shown, the liquid jetting unit 4 is the part that performs the liquid jetting process of spraying liquid 101 onto the fabric and causing the liquid to collide. The liquid jetting unit 4 includes: at least one nozzle 41 for spraying liquid 101; a liquid tank 43 for storing the sprayed liquid 101; a pump 42 for transporting the liquid 101 from the liquid tank 43 to the liquid jetting unit 4; and an intermediate roller 24, which serves as a support roller to support the fabric 100 being transported within the liquid jetting unit 4. In this embodiment, from... Figure 1 Multiple nozzles 41 are arranged on the paper surface and the front side facing inward, that is, along the width direction of the fabric 100 being conveyed. The number of nozzles 41 is not particularly limited, for example, it can be more than 2 and less than 100. The number of nozzles 41 is appropriately determined according to the material, characteristics, width and other conditions of the fabric 100.

[0050] The configuration of the multiple nozzles 41 is not particularly limited. In this embodiment, from Figure 1 The paper can be arranged in one column with the front side facing inward, but it can also be arranged in two or three or more columns.

[0051] like Figure 2As shown, the nozzle 41 includes: a first portion 44 having a liquid inlet 412, for example, a cylindrical internal space; and a second portion 45 formed above the first portion 44 having a jet nozzle hole 411 communicating with the liquid inlet 412 and a cone 413 thereafter.

[0052] Liquid inlet 412 is the inlet for liquid to flow into the jet nozzle orifice 411. The jet nozzle orifice 411 is circular. Here, the nozzle orifice diameter of the jet nozzle orifice 411 is set as d [mm], and the diameter of the liquid inlet 412 is set as D [mm].

[0053] The liquid 101, pressurized by pump 42 and flowing into liquid inlet 412, becomes a high-pressure jet and flows out from jet nozzle orifice 411 towards... Figure 2 Spray from the upper middle. Figure 2 The symbol F in the figure indicates the direction of liquid 101 injection.

[0054] The jet of liquid 101 ejected from the nozzle orifice 411 is a continuous flow immediately after ejection, but it immediately droplets due to the surface tension of the liquid 101 and breaks into a group of droplets. The prescribed treatment is performed by causing the group of droplets to collide with the fabric 100 successively.

[0055] Furthermore, the nozzle 41 ensures that the droplets fly with good linearity from the end face of the ejection side of the nozzle orifice 411 in the liquid ejection direction F, for example, within a range of 100 mm to 150 mm.

[0056] like Figure 2 As shown, the nozzle orifice diameter d of the spray nozzle orifice 411 is 0.01 mm ≤ d ≤ 0.30 mm. Furthermore, the ratio D / d of the diameter D of the liquid inlet 412, which serves as the inlet for the liquid 101 to flow into the spray nozzle orifice 411, to the nozzle orifice diameter d satisfies 5 ≤ ​​D / d ≤ 150. Therefore, the liquid spraying process can be performed effectively. That is, the fiber arrangement of the fabric 100 can be disrupted, the crossing positions of intersecting fiber bundles can be staggered, and local structural damage can be achieved. Therefore, the surface of the fabric 100 can have a good napping condition, improving the texture of the fabric 100.

[0057] The preferred range for the nozzle orifice diameter d is 0.02mm≤d≤0.25mm, and the more preferred range is 0.02mmd≤0.15mm.

[0058] The preferred range for the ratio D / d is 8 ≤ D / d ≤ 80.

[0059] The reasons for the above values ​​are explained below.

[0060] If the nozzle orifice diameter d of the spray nozzle orifice 411 is too large, the droplets of liquid 101 that collide with the fabric 100 will be too large, and depending on the type of fiber of the fabric 100, they may not be handled well. In addition, there is a tendency for the distance from when the sprayed liquid 101 is sprayed to when it becomes a droplet to become longer, which may lead to the need for larger devices.

[0061] On the other hand, if the nozzle orifice diameter d of the spray nozzle orifice 411 is too small, the sprayed droplets will be too small, and depending on the type of fiber of the fabric 100, they may not be processed well.

[0062] If the ratio D / d is too large, the diameter D of the liquid inlet 412 will be too large, or the nozzle orifice d will be too small. Depending on the type of fiber in the fabric 100, it may not be able to be processed well.

[0063] On the other hand, if the ratio D / d is too small, the diameter D of the liquid inlet 412 will be too small, or the nozzle orifice d will be too large, and depending on the type of fiber of the fabric 100, it may not be able to be processed well.

[0064] The shape of the liquid inlet 412, i.e., its cross-sectional shape, is circular when there is only one injection nozzle orifice 411, and elliptical or oblong when there are multiple orifices. Furthermore, the shape of the liquid inlet 412 is not limited to circular, elliptical, or oblong; it can also be square, rectangular, etc. When the liquid inlet 412 has an elliptical or oblong shape, the diameter D is the average of the major and minor axes. When the liquid inlet 412 has a square or rectangular shape, the diameter D is the dimension of one side of the square, and the average dimension of the short and long sides of the rectangle.

[0065] The injection pressure of the liquid 101 ejected from the injection nozzle orifice 411 is preferably 0.2 MPa to 10 MPa, more preferably 2 MPa to 8 MPa. This allows for more reliable and efficient processing of the fabric 100.

[0066] In addition, such as Figure 2 As shown, the nozzle 41 has a structure in which the inner diameter narrows sharply from D to d in the flow direction of the liquid 101. Therefore, the liquid 101, which is capable of being sprayed, is less likely to come into contact with the narrowing of the inner surface of the nozzle orifice 411. Thus, it is less affected by the surface roughness of the inner surface of the nozzle orifice 411, and can easily form droplets of uniform size.

[0067] Specifically, the nozzle 41 has a tapered portion 413 on the liquid outflow side of the second portion 45, which serves as the injection nozzle orifice 411, that expands in diameter toward the liquid injection direction F. The tapered portion 413 has the function of increasing the mechanical strength of the nozzle 41, which has a relatively small nozzle orifice diameter d. In addition, the tapered portion 413 has the function of limiting the flight range of the liquid droplets 101 ejected from the injection nozzle orifice 411.

[0068] The angle θ of the cone 413 is not particularly limited, for example, it can be between 30° and 150°. In the configuration shown in the figure, θ is approximately 90°, but the angle can be increased or decreased within the range where it is easy to form the injection nozzle hole 411.

[0069] When spraying liquid 101 onto fabric 100, the distance between the spray nozzle orifice 411 and fabric 100 is not particularly limited, but... Figure 2 When the average distance shown is set to S, it is preferably 5mm ≤ S ≤ 200mm, and more preferably 50mm ≤ S ≤ 150mm. By setting S to a value within this range, the impact of the liquid 101 on the fabric 100 will not be excessive or insufficient, and better processing can be achieved.

[0070] A pump 42 is provided in the flow path between the nozzle 41 and the liquid tank 43. The operation of the pump 42 is controlled by the control unit 6 to transport the liquid 101 to the liquid inlet 412 so that the injection pressure of the liquid 101 ejected from the injection nozzle orifice 411 is, for example, the value described above.

[0071] An intermediate roller 24 is positioned below the intermediate roller 23. Fabric 100 is wound around the outer circumference of the intermediate roller 24, causing the fabric 100 to deform downwards into a curved, protruding shape. This deformation is used to convey and support the fabric 100. A nozzle 41 sprays liquid droplets onto the fabric 100 supported by the intermediate roller 24. Specifically, the nozzle 41 sprays liquid 101 onto the fabric 100, which conforms to the curved shape of the intermediate roller 24 and bends towards the nozzle 41, causing the liquid to collide with the fabric. This stabilizes the movement of the fabric 100 as it is struck by the liquid 101, allowing for further, more efficient processing.

[0072] As for liquid 101, various types of water can be listed, such as tap water, industrial water, well water, pure water, RO water, etc.

[0073] The liquid removal unit 5 is the part that performs the drying process. It includes an intermediate roller 25, which serves as a heating roller, a housing 51 covering the upper side of the intermediate roller 25, and an air supply unit 52 that supplies air between the housing 51 and the intermediate roller 25. Here, drying in the drying process refers to removing or reducing the moisture adhering to or impregnating the fabric 100, regardless of whether heating is used. In this sense, the drying process can be considered an example of a liquid removal process that removes liquid 101 adhering to or impregnating the fabric 100. Other examples of liquid removal processes include a dehydration process in which pressure is applied to the fabric 100 to remove water.

[0074] Intermediate roller 25 is positioned above intermediate roller 23 and intermediate roller 24. Figure 1 In the middle, rotating clockwise. The intermediate roller 25 wraps the fabric 100 around its outer circumference, deforming the fabric 100 upward into a curved protrusion, conveying and supporting the fabric 100 in a manner that maintains this state.

[0075] The fabric 100 is heated and dried by contacting the outer peripheral surface of the heated intermediate roller 25 for a predetermined time. In this embodiment, the surface of the fabric 100 that collides with the liquid 101 is in contact with the outer peripheral surface of the intermediate roller 25, while the opposite surface is not in contact with the outer peripheral surface of the intermediate roller 25. This is because, comparing the surface of the fabric 100 that collides with the liquid 101 and the opposite surface, the drying efficiency is higher when the heated roller contacts the former, and the processing effect is also better. However, in this invention, the surface in contact between the heated roller and the fabric 100 is not limited to this; it may be configured such that only the surface opposite to the surface of the fabric 100 that collides with the liquid 101 is in contact, or that multiple heated rollers are arranged so that both surfaces of the heated roller and the fabric 100 are in contact.

[0076] The housing 51 is a component having an inner surface that is curved to resemble the upper outer peripheral surface of the intermediate roller 25, and has the function of forming an airflow that flows along the surface of the fabric 100 wound around the intermediate roller 25. Furthermore, the interior of the housing 51, i.e., the side of the intermediate roller 25, has an air intake 511 for drawing in air. An air supply section 52 is connected to the air intake 511.

[0077] Although not shown, the air supply unit 52 includes an electric motor and a fan driven by the electric motor, which supplies air to the intake port 511 at a predetermined airflow rate. The air supply unit 52 is powered by a control unit 6, which adjusts the airflow rate and the timing of air delivery.

[0078] When the air supply unit 52 operates, air drawn in from the intake port 511 forms an airflow along the surface of the fabric 100 between the housing 51 and the intermediate roller 25. This airflow dries the fabric 100 conveyed on the outer circumferential surface of the intermediate roller 25. That is, it removes or reduces the liquid 101 adhering to or impregnating the fabric 100.

[0079] like Figure 1 As shown, since the suction port 511 is located at the top of the housing 51, the air drawn in from the suction port 511 is divided into arrow directions A1 and A2, which are opposite to each other, near the uppermost part of the intermediate roller 25. That is, an airflow is formed from the suction port 511 towards the upstream side of the conveying direction and an airflow towards the downstream side of the conveying direction. To explain in more detail, in the first half of the drying process, drying is carried out by airflow in the opposite direction to the conveying direction of the fabric 100 (counter-current), and in the second half of the drying process, drying is carried out by airflow in the same direction as the conveying direction of the fabric 100 (co-current). As a result, in the first half of the drying process, the relative velocity of the airflow with respect to the conveyed fabric 100 is faster than in the second half of the drying process, thus enabling efficient drying.

[0080] The ratio of the airflow rate upstream in the conveying direction to the airflow rate downstream in the conveying direction is not particularly limited, and can be appropriately set in the range of 1:5 to 5:1. In this embodiment, it is 1:1.

[0081] Alternatively, although not shown, a variable-angle rectifier plate can be installed inside or directly below the inlet 511 to adjust the ratio of the airflow rate upstream in the conveying direction to the airflow rate downstream in the conveying direction. In this case, either the airflow rate upstream in the conveying direction or the airflow rate downstream in the conveying direction can be 0.

[0082] A heater 53 is installed at the center of the intermediate roller 25. Through the operation of the heater 53, the outer peripheral surface of the intermediate roller 25 is heated to a predetermined temperature. The heater 53's energizing conditions are controlled by the control unit 6, thus regulating the heat output. As a result, the outer peripheral surface of the intermediate roller 25 is heated to a desired temperature, for example, a predetermined temperature of 35°C to 95°C. Therefore, compared to the case where airflow is generated solely by the air supply unit 52, the drying efficiency is significantly improved.

[0083] Furthermore, the temperature of the airflow supplied by the air supply unit 52 can be ambient temperature, or it can be configured such that a heater (not shown) is installed on the outlet side of the air supply unit 52, and the heated warm air is supplied to the inlet 511, i.e., a heating and drying configuration is performed. In this case, the temperature of the airflow can also be adjusted by controlling the power supply conditions through the control unit 6. The temperature of the airflow can be, for example, a specified temperature of 35°C or higher and 95°C or lower.

[0084] By undergoing this drying process, i.e., the liquid removal process, the liquid 101 contained in the fabric 100 after the liquid spraying process can be thoroughly removed. As a result, due to the reduced moisture content and weight of the fabric 100, the inertial weight of the fabric 100 is reduced when vibration is applied in the vibration application process described later, and the propagation of vibration is also improved. Therefore, vibration is propagated and applied to the fabric 100 as a whole, fully and rapidly. Thus, the vibration application process can be performed more effectively.

[0085] Furthermore, by using the liquid removal unit 5 to dry the fabric 100, particularly by using airflow or heating, the drying efficiency is higher compared to naturally drying the fabric 100 after the liquid spraying process. Therefore, the transport path length of the fabric 100 can be shortened. As a result, the device can be miniaturized. In addition, the drying time is shortened, and the total processing time is also reduced.

[0086] In addition, the drying of the fabric 100 in the drying process can be carried out by either forming an airflow using the air supply section 52 or heating the intermediate roller 25 using the heater 53, but the synergistic effect produced by combining the two can achieve efficient drying and also help to further shorten the conveying path length and drying time required for drying.

[0087] Furthermore, prior to the drying process, a dehydration process, such as applying pressure to the fabric 100 to remove water as another example of the aforementioned liquid removal process, can be added. This further shortens the drying time in the drying process.

[0088] The vibration imparting unit 3 is the part that performs the vibration imparting process, which imparts vibration to the fabric 100 after the liquid spraying process and the drying process. For example... Figure 3 As shown, the vibration imparting process includes a pair of contacting members 36 and a pair of corresponding vibration generating sources 32. The vibration imparting unit 3 has the function of imparting vibration to the conveyed fabric 100. This allows for surface treatment of the fabric 100. Furthermore, the treatments performed on the fabric 100 by the vibration imparting unit 3 include "curling," "beating," "stretching," and "sliding friction." In this embodiment, the treatments performed by the vibration imparting unit 3 are equivalent to "curling" and "beating." This will be explained in detail later.

[0089] In this embodiment, the abutting members 36 are respectively disposed on the upper and lower sides of the conveyed fabric 100 in the thickness direction. That is, the fabric 100 is conveyed between a pair of abutting members 36 disposed in the vertical direction.

[0090] All abutting parts 36 have the same structure except for their different positions, so one abutting part 36 will be described below as representative.

[0091] like Figure 3 As shown, the abutting member 36 has a plate-like or block-like base 361 and a plurality of protrusions 362 protruding from the base 361. A pair of abutting members 36 are arranged vertically across the conveying path of the fabric 100. The protrusions 362 protrude from the base 361 toward the conveying path of the fabric 100. Vibration generated by the vibration generating source 32 causes the base 361 of the abutting member 36 to vibrate, and this vibration is propagated through the protrusions 362 and imparted to the fabric 100. Thus, the fabric 100 is given localized and sufficient vibration, allowing for more efficient processing. As a result, a good texture can be obtained.

[0092] In this embodiment, the protrusion 362 is made of a cylindrical rigid body. However, it is not limited to this configuration; the protrusion 362 may also be spherical, conical, or plate-shaped.

[0093] Furthermore, for each abutting part 36, the protrusions 362 located on opposite sides of each other across the fabric 100 are positioned relative to each other from the base 361. Figure 3 From a top-down view (hereinafter referred to as "top view"), the parts can be arranged without overlapping, i.e., staggered, forming a so-called interlaced shape. Therefore, even if the amplitude of the vibration is relatively large, interference between the protrusions 362 can be prevented. Thus, it has the advantage of fully obtaining the curling effect of the fabric 100 imparted by the vibration part 3.

[0094] Furthermore, the protrusions 362 on the opposite side of the fabric 100 can be kept separate when viewed from above the fabric 100. In this case, a high-impact effect, as described later, can be obtained.

[0095] Based on such abutting member 36, the fabric 100 can be rolled and beaten, and the fabric 100 can be treated well.

[0096] The curling refers to the following situation.

[0097] If a predetermined tension is applied to the fabric 100 and the abutment member 36 is vibrated while the fabric 100 is in contact with the protrusion 362 of the abutment member 36, the fabric 100 will deform with an increased fiber curl angle, using the end of the protrusion 362 as the fulcrum P. By repeatedly performing this action, the cohesive force between parallel fibers is eased, the junctions of intersecting fiber bundles are released, and the local structure of the fibers is disrupted. This reduces the rigidity of the fabric 100.

[0098] Furthermore, when applying vibration, it is preferable to reduce the contact area between the protrusion 362 and the fabric 100, and increase the curling angle or bending angle relative to the fulcrum formed when applying vibration. That is, it is preferable to increase the distance between adjacent fulcrums P to a certain extent, so that the amplitude caused by the deformation of the fabric 100 when applying vibration to the fabric 100 increases. As a result, the amplitude of the fabric 100 caused by the transmitted vibration energy increases, the curling angle of the fibers increases, and therefore, the rigidity of the fabric 100 can be further reduced, resulting in a better texture.

[0099] Furthermore, when applying vibration, it is preferable to apply vibration period / amplitude and tension corresponding to the inherent vibration frequency of the fabric 100. This brings the fabric 100 into a resonant state. Therefore, by repeatedly performing effective curling movements with small vibrational energy, the texture of the fabric 100 can be effectively improved.

[0100] The tapping refers to the following situations.

[0101] A small tension is applied to the fabric 100, and the contact member 36 is vibrated while both sides of the fabric 100 are engaged. At this time, to cause the protrusions 362 to cross or collide with each other in a direction perpendicular to one side and another side of the fabric 100, the fabric 100 is vibrated while the protrusions 362 are engaged with each other on both sides of the fabric 100. The fabric 100 repeatedly compresses and restores its fiber bundles through this vibration. This causes disorder in the arrangement of parallel fibers, misalignment of the crossing positions of intersecting fiber bundles, and local structural damage to the fibers. As a result, the gaps between fibers widen, the distance between fiber bundles increases, and fuzzing caused by partial fiber cutting occurs, increasing the fluffiness of the fabric and improving its texture.

[0102] Furthermore, in order to prevent the upper and lower protrusions 362 from contacting each other, for example, in the case of an alternating arrangement, the fabric 100 deformed by the protrusions 362 can simultaneously and repeatedly perform a relatively weak tapping action caused by collision with the base 361 of the abutting member 36 and a relatively weak curling action with the end of the protrusion 362 as the fulcrum P, which can effectively improve the texture of the fabric 100.

[0103] Furthermore, when the protrusions 362 are repeatedly positioned as the fabric 100 falls and bounces freely due to gravity, the fabric 100 is subjected to strong concentrated stress from both sides within a short period of time due to the collisions between the protrusions 362, and the fiber bundles are repeatedly compressed and restored. At this time, the arrangement of parallel fibers becomes disordered, the crossing positions of intersecting fiber bundles are misaligned, and the local structure of the fibers is damaged. As a result, the gaps between fibers widen, the distance between fiber bundles increases, and the fuzzing caused by the cutting of some fibers increases the fluffiness of the fabric, effectively improving the texture of the fabric 100.

[0104] Through the effects of curling and beating described above, the quality of the fabric 100 can be significantly improved.

[0105] The end of the protrusion 362 is preferably rounded. This more effectively prevents the protrusion 362 from damaging the fabric 100. Alternatively, the end of the protrusion 362 can also be pointed. Furthermore, when the protrusion 362 has a rounded corner, the curvature of the end 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 effectively suppresses the formation of processing marks caused by the impact of the protrusion 362, even when printing on the surface of the fabric 100.

[0106] The length of the protrusion 362, that is, the length from the base 361 to the front end of the protrusion 362, is preferably 1 mm to 100 mm, more preferably 10 mm to 50 mm. Therefore, when the protrusion 362 is vibrated in a state where the vertical directions relative to one side of the fabric 100 and the vertical directions relative to the other side intersect, the striking effect of the upper and lower protrusions 362 can be improved.

[0107] The material used to construct the protrusion 362 is not particularly limited; various resin materials, metal materials, and ceramic materials can be listed. From the viewpoint of achieving good napping, a metal material is preferred. As for the metal material, there are no particular limitations; brass, steel, and stainless steel are preferred. Using steel allows for more reliable napping. When the fabric 100 is colored with pigment, using brass allows for napping while suppressing damage to the colored areas.

[0108] The vibration source 32 has an oscillator 321 that generates vibration. The oscillator 321 is electrically connected to the control unit 6. Furthermore, the control unit 6 controls the conditions for energizing the oscillator 321, thereby adjusting the vibration conditions and characteristics of the oscillator 321.

[0109] Furthermore, the vibration generating source 32 has a vibration transmission component 322. The vibration transmission component 322 is made of a rigid body and connects the outer shell containing the vibrator 321 to the base 361 of the contact component 36, transmitting the vibration generated by the vibrator 321 to the contact component 36. Thus, vibration can be transmitted to the fabric 100 via the contact component 36.

[0110] The amplitude of the vibration imparted to the fabric 100 is preferably 0.1 mm to 100 mm, more preferably 0.2 mm to 80 mm. This allows for more efficient processing of the fabric 100.

[0111] Furthermore, the frequency of the vibration imparted to the fabric 100 is preferably 1 Hz to 1000 Hz, more preferably 10 Hz to 100 Hz. This allows for more efficient processing of the fabric 100.

[0112] Furthermore, the vibration imparted to the fabric 100 preferably includes the vibration along the thickness direction of the fabric 100 during transport, i.e. Figure 3 The components are distributed vertically. This allows for more efficient processing.

[0113] Furthermore, the vibration imparted to the fabric 100 preferably includes a component along the conveying direction of the fabric 100 during transport. This allows for more efficient processing.

[0114] Furthermore, the vibration imparted to the fabric 100 preferably includes a component along the direction intersecting with the conveying direction of the fabric 100, particularly the width direction of the fabric 100 being conveyed. This allows for better processing.

[0115] In this embodiment, for Figure 3 The vibration imparting unit 3 has been described, but its configuration is not limited to this. For example, a brush roller (not shown) may be additionally provided on the upstream or downstream side of the conveying direction of the contact member 36, so that the brush of the rotating brush roller abuts against the fabric 100 being conveyed. Alternatively, it may be replaced with... Figure 3 The abutting member 36 shown uses a brush roller as the abutting member. In these cases, it is possible to perform a process that generates stretching and sliding friction. In addition, such a brush roller can be disposed on both sides of the fabric 100, or it can be disposed on only one side.

[0116] The extension refers to the following situation.

[0117] While applying a relatively large tension to the fabric 100, the contacting member 36 is subjected to a small-period, large-amplitude vibration while the back of the fabric 100 is in contact with the brush bristles. At this time, due to the relatively large tension acting on the fabric 100, the fabric 100 repeatedly stretches and softens according to the phase of the brush bristles. By causing the fiber bundles constituting the fabric 100 to repeatedly stretch and contract around the contact point with the brush bristles, minute embossed residual strain can be formed in the non-stretchable fabric 100. This minute embossed residual strain has the effect of increasing the fluffiness of the non-stretchable fabric, effectively improving the texture of the fabric 100.

[0118] The sliding friction refers to the following situation.

[0119] While applying a specified tension to the fabric 100, vibration is applied to the vibration transmission component while the surface of the fabric 100 is in contact with the brush bristles. As a result, the brush bristles do not penetrate the fabric 100, maintaining contact and effectively transmitting vibrational energy. Consequently, the surface of the fabric 100 exhibits good napping.

[0120] As described above, the processing method of the present invention includes: a liquid spraying step, in which liquid 101 is sprayed from a spray nozzle hole 411 of a liquid spraying section 4 having at least one nozzle 41 onto a fabric 100 and the liquid 101 is impacted, the nozzle 41 having a spray nozzle hole 411 and a liquid inlet 412 serving as an inlet for the liquid to flow into the spray nozzle hole 411; and a vibration imparting step, in which vibration is imparted to the fabric 100 after the liquid spraying step, wherein when the nozzle hole diameter of the spray nozzle hole 411 is set to d [mm] and the diameter of the liquid inlet 412 is set to D [mm], the following conditions are satisfied: 0.01mm≤d≤0.30mm and 5≤D / d≤150.

[0121] Through this processing method of the present invention, the fabric 100 is well treated. In particular, the treated fabric 100 has a good texture. More specifically, the fabric 100 is treated by two different methods of impact and vibration with liquid 101, and through their synergistic effect, the texture becomes excellent.

[0122] Furthermore, the processing apparatus of the present invention includes: a conveying unit 2 for conveying fabric; a liquid spraying unit 4 having at least one nozzle 41 having a spray nozzle orifice 411 and a liquid inlet 412 serving as the inlet for the spray nozzle orifice 411, spraying liquid 101 from the spray nozzle orifice 411 onto the fabric 100 and causing the liquid 101 to collide; and a vibration imparting unit 3 that, after the liquid collides with the fabric 100, imparts vibration to the fabric 100 conveyed by the conveying unit 2, wherein when the nozzle orifice diameter of the spray nozzle orifice 411 is set to d [mm] and the orifice diameter of the liquid inlet 412 is set to D [mm], the following conditions are satisfied: 0.01mm≤d≤0.30mm and 5≤D / d≤150.

[0123] The fabric 100 is effectively treated using this processing apparatus of the present invention. In particular, the treated fabric 100 achieves a superior texture. More specifically, the fabric 100 is treated by two different methods—impact and vibration—through the synergistic effect of the liquid 101, resulting in an excellent texture.

[0124] In the liquid spraying step of the processing method, one side of the fabric 100 is supported by an intermediate roller 24, which serves as a support roller, and the liquid 101 collides with the other side of the fabric 100. This allows the liquid to collide while the fabric 100 is in a stable operating state, thus enabling better processing.

[0125] In the vibration-imparting step of the processing method, the vibration-imparting unit 3, which has an abutment member 36 and a vibration-generating source 32, imparts vibration to the fabric 100 via protrusions 362. The abutment member 36 has a base 361 and multiple protrusions 362 that protrude from the base 361 and abut against the fabric 100. The vibration-generating source 32 imparts vibration to the abutment member 36. This provides localized and sufficient vibration to the fabric 100, resulting in more effective processing. Consequently, a good texture can be obtained.

[0126] The processing method includes a liquid removal step, performed between the liquid spraying step and the vibration application step, to remove liquid 101 adhering to or impregnating the fabric 100. As a result, when vibration is applied to the fabric 100 through the vibration application step, the inertial weight of the fabric 100 decreases, and the propagation of the vibration is improved. Therefore, vibration-based processing can be performed more effectively.

[0127] Furthermore, in the liquid removal process, the surface of the fabric 100 that collides with the liquid 101 is brought into contact with the intermediate roller 25, which serves as a heating roller. As a result, the fabric 100 can be dried efficiently, i.e., liquid removal, with a shorter path, which helps to shorten the total processing time and reduce the size of the processing device.

[0128] Furthermore, in this embodiment, the fabric 100 is processed continuously, but the present invention is not limited to this. At least one of the liquid spraying process, liquid removal process, and vibration imparting process performed on the fabric 100 can also be processed in batches.

[0129] <Second Implementation Method>

[0130] Figure 4 This is a schematic configuration diagram of a second embodiment of a processing apparatus for performing the processing method of the present invention. Figure 5 It is shown Figure 4 A partial cross-sectional side view of the state in which the vibration imparting unit of the processing device imparts vibration to the fabric. Figure 6 It is shown Figure 4 A partial cross-sectional side view of the state in which the vibration imparting unit of the processing device imparts vibration to the fabric.

[0131] Hereinafter, a second embodiment of the processing method and processing apparatus of the present invention will be described with reference to these figures, but the description will focus on the differences from the first embodiment described above, and the same items will be omitted from the description.

[0132] The processing method of the second embodiment of the present invention is as follows: Figure 4 The processing device 1 shown is used for execution.

[0133] like Figure 4 As shown, the liquid removal section 5, located downstream of the liquid injection section 4 in the conveying direction, has a dehydration section 7 and a drying section 8 located further downstream of the dehydration section 7 in the conveying direction.

[0134] Furthermore, the conveying unit 2 includes a pair of intermediate rollers 27, 28, 29, and 30. These intermediate rollers are arranged between the drying unit 8 and the winding unit 22 along the conveying path of the fabric 100. From the extraction unit 21 towards the winding unit 22, i.e., from the upstream side of the conveying direction towards the downstream side, the intermediate rollers 27, 28, 29, and 30 are sequentially arranged along the conveying path of the fabric 100. The intermediate rollers 27, 28, 29, and 30 function as conveying rollers that transport the fabric 100 from the upstream side to the downstream side of the conveying path.

[0135] A pair of intermediate rollers 27 rotate in opposite directions with one contacting one side of the fabric 100 and the other contacting the other side of the fabric 100. This allows the fabric 100 to be transported from the drying section 8 to the vibration imparting section 9. Furthermore, the pair of intermediate rollers 27 are positioned above the vibration imparting section 9 to fold the fabric 100 downwards and transport it.

[0136] A pair of intermediate rollers 28 rotate in opposite directions with one side of the fabric 100 in contact with the other side of the fabric 100. This allows the fabric 100 to be fed from the vibration-imposing section 9 to the take-up section 22. Furthermore, the pair of intermediate rollers 28 are positioned below the vibration-imposing section 9 to fold the fabric 100 back to the right in the figure and transport it.

[0137] Intermediate roller 29 is in contact with the upper surface of fabric 100, and intermediate roller 30 is in contact with the upper surface of fabric 100.

[0138] A pair of intermediate rollers 27, a pair of intermediate rollers 28, intermediate rollers 29 and intermediate rollers 30 can be either self-rotating drive rollers or self-driven rollers without rotational drive force.

[0139] When the pair of intermediate rollers 27, the pair of intermediate rollers 28, the intermediate rollers 29 and the intermediate roller 30 are active rollers, each roller has a built-in or connected motor (not shown), and the conditions for energizing each motor are controlled by the control unit 6.

[0140] The dewatering section 7 is located downstream of the liquid jetting section 4 in the conveying direction and has the function of removing or reducing the moisture adhering to or impregnating the fabric 100. The dewatering section 7 is the part that performs the dewatering process and has a pair of squeeze rollers 71.

[0141] A pair of squeeze rollers 71 rotate in opposite directions with one contacting the upper surface of the fabric 100 and the other contacting the lower surface of the fabric 100. Furthermore, the pair of squeeze rollers 71 apply force towards each other via a force-applying member (not shown), pressurizing the passing fabric 100 to squeeze out and dehydrate the water contained in the fabric 100. The water squeezed out from the fabric 100 is recovered by the recovery container 72.

[0142] Thus, the fabric 100, which has been coated or impregnated with water by the liquid spray section 4, is squeezed as it passes between a pair of squeeze rollers 71, i.e., dehydrated and its moisture content is reduced, and then it is sent to the drying section 8 in this state. In addition, the dehydration process performed by the dehydration section 7 can be said to be part of the liquid removal process that removes or reduces the moisture adhering to or impregnating the fabric 100.

[0143] In addition, Figure 4 In the configuration shown, a scraper-like scraper can be used instead of the squeeze roller 71. For example, a pair of scraper-like scrapers made of an elastomer can be arranged to hold the fabric 100 in a clamping manner, and the moisture adhering to or impregnating the fabric 100 can be squeezed by the two scrapers to dehydrate it.

[0144] By appropriately setting the surface properties, such as surface roughness, of the contact surface between the extrusion roller 71 or the scraper and the fabric 100, and thus appropriately setting the contact pressure of the contact surface on the fabric 100, the fabric 100 can be processed better, and in particular, its texture can be further improved.

[0145] The drying section 8 is located downstream of the dewatering section 7 in the conveying direction and has the function of removing or reducing moisture adhering to or impregnating the fabric 100, that is, removing or reducing moisture remaining on the fabric 100 after dewatering. The drying section 8 is the part that performs the drying process and has three return rollers 81, 82, and 83. The return rollers 81, 82, and 83 are arranged sequentially from the upstream side to the downstream side.

[0146] The return rollers 81 and 83 are of the same height and are arranged separately to the left and right. The return roller 82 is arranged below the return rollers 81 and 83. In addition, the return roller 82 is arranged between the return rollers 81 and 83 in the left-right direction in the figure.

[0147] The return rollers 81 and 83 contact the lower surface of the fabric 100, and the return roller 82 contacts the upper surface of the fabric 100. The fabric 100 is configured to fold back at three points, reciprocating once in the vertical direction during its passage through the return rollers 81, 82, and 83. Furthermore, the fabric 100 undergoes natural drying during this single reciprocating motion. The conveying path required for this natural drying is set to be sufficiently long. Additionally, the conveying path in the drying section 8 is not limited to the configuration shown in the figure; for example, a conveying path with one and a half or two or more reciprocating motions in the vertical direction may be provided. Moreover, the direction of reciprocation is not limited to the vertical direction.

[0148] In the second embodiment, by providing a dehydration section 7 upstream of the drying section 8, i.e., performing a dehydration process before the drying process, the load on the drying process is reduced, resulting in high drying efficiency. Therefore, even if the drying in the drying section 8 is set to natural drying, sufficient drying can be achieved in a relatively short time.

[0149] Furthermore, in the processing apparatus 1 of the second embodiment, the... Figure 4 The vertical conveying path is set to one or more reciprocating cycles, and a drying section 8 is installed on this vertical conveying path, thus shortening the conveying path. Figure 4 The length in the left-right direction. Therefore, it is possible to achieve miniaturization of the device and space-saving device installation.

[0150] The drying unit 8, configured as described above, can dry the fabric 100 by natural drying. With this drying unit 8, the electrical energy required for drying can be saved because a heater for heating can be omitted. The drying process performed by the drying unit 8 can be considered part of a liquid removal process that removes or reduces moisture adhering to or impregnating the fabric 100.

[0151] Furthermore, in the second embodiment, the drying unit 8 can also be configured in other ways, such as heating drying, cold air drying, or warm air drying as in the first embodiment. Additionally, in the second embodiment, the dehydration unit 7 can be omitted.

[0152] like Figures 4-6 As shown, a vibration-inducing part 9 is provided on the conveying path extending vertically in the same figure, and this vibration-inducing part 9 induces vibration in the fabric 100 conveyed downwards in the same figure. However, the present invention is not limited to this; it can also be used to induce vibration in the direction of... Figures 4-6 The fabric 100 conveyed in the upper or left-right direction is given a vibrational structure.

[0153] like Figures 4-6 As shown, the vibration imparting part 9 has a pair of abutting parts 91, a vibration generating source 92, and a vibration transmitting part 93, which are arranged separately with the fabric 100 between them.

[0154] A pair of abutting members 91 each have a plate-shaped base 911 and a plurality of protrusions 912 protruding from the base 911. The abutting members 91 are arranged in a left-right direction across the conveying path of the fabric 100. The protrusions 912 protrude from the base 911 toward the conveying path of the fabric 100. The protrusions 912 on the left and right sides of the figure protrude from the base 911... Figure 5 The two structures are staggered when viewed from the left-center direction.

[0155] The vibration generating source 92 has a pair of electric motors 921 and a pair of cams 922 respectively fixed to each electric motor 921. The cams 922 are fixed to the output rotation shaft of the electric motors 921 and abut against the base 911 of one of them. Furthermore, both cams 922 are elliptical in shape when viewed from the direction of the output rotation shaft of the electric motors 921. Each electric motor 921 is controlled by a control unit and rotates at the same speed when energized. Driven by each electric motor 921, the cams 922 rotate, resulting in… Figure 5 The state of the major axis along the left and right directions shown and Figure 6 The short shaft is shown in its left-right direction. The two cams 922 are of the same shape and size, and rotate in the same direction, at the same speed, and in the same phase.

[0156] In addition, although Figure 5 as well as Figure 6Although not explicitly stated, multiple cams 922 can be fixed at predetermined intervals along the length of the output rotation axis of a motor 921, i.e., the width of the fabric 100. In this case, the multiple cams 922 are of the same shape and size, and preferably rotate in the same direction, at the same speed, and in the same phase, but are not limited thereto.

[0157] The vibration transmission unit 93 includes a support plate 931, a support plate 932, a pair of connecting portions 933 connecting the support plate 931 and the support plate 932, and a pair of force-applying portions 934. The support plate 931 supports each motor 921. The support plate 932 is separated from the support plate 931 by an abutment member 91 and a vibration generation source 92, and is arranged parallel to it. The support plate 932 supports the abutment member 91 on the left side of the pair of abutment members 91 shown in the figure.

[0158] The connecting part 933 is rod-shaped and is disposed between the support plate 931 and the support plate 932, fixing them in a positional relationship that is spaced at a predetermined interval. Figure 5 On the base 911 of the right-side abutment member 91, there is formed a... Figure 5 A pair of through holes 915 are arranged separately in the vertical direction, and a connecting part 933 is inserted into each through hole 915. Thus, Figure 5 The abutting member 91 on the right side is movable along the length of the connecting part 933. The movement of the abutting member 91 is generated by the drive of each motor 921, and the two abutting members 91 repeatedly approach and separate.

[0159] The force-applying part 934 is composed of a helical spring and is disposed on the outer periphery of the connecting part 933 and between the two base parts 911. The force-applying part 934 is disposed in a compressed state, which... Figure 5 The right-side contacting member 91 applies force toward the vibration source 92. Therefore, Figure 5 The base 911 of the right-side contacting member 91 is independent of the rotation angle of the cam 922 and maintains contact with the outer peripheral surface of the cam 922, i.e., the cam surface.

[0160] Based on this configuration, the rotation of the cam 922, driven by the electric motor 921, Figure 5 The right-side contact component 91 repeatedly moves from... Figure 5 The state transition shown Figure 6 The state shown, and then return to Figure 5 A series of actions in the state shown. At this time, through the force applied by the force-applying part 934, Figure 5The base 911 of the right-side abutment member 91 remains pressed by the cam surface of the cam 922, thus generating regular vibrations on the abutment member 91. These vibrations are transmitted to the fabric 100, which contacts the protrusion 912 of the abutment member 91. Therefore, the fabric 100 can be properly treated, improving its texture.

[0161] exist Figure 5 In the state shown, the abutting part 91 on the right side of the figure is closest to the abutting part 91 on the left side of the figure. Figure 6 In the state shown, the abutting member 91 on the right side of the same figure is separated from the abutting member 91 on the left side of the same figure to the maximum extent. The difference in the separation distance between the two abutting members 91 corresponds to the amplitude of the vibration imparted by the vibration imparting unit 9.

[0162] Therefore, for example, by appropriately selecting the shape of the cam 922 used, such as the dimensions of the major and minor axes of an ellipse, the amplitude of the vibration imparted to the fabric 100 can be adjusted. Furthermore, the shape of the cam 922 used can be set to any shape other than an ellipse, thereby allowing the vibration mode or vibration characteristics imparted to the fabric 100 to be appropriately set.

[0163] Furthermore, by using one cam 922 and the other cam 922, a phase difference can be set for the rotation, or the shape or size can be made different, thereby allowing the vibration mode or vibration characteristics of the fabric 100 to be appropriately set.

[0164] In the processing apparatus 1 of the second embodiment, the vibration imparting unit 9 is directed towards Figure 4 Vibration is applied to the fabric 100 in the lower middle conveying path, thus shortening the conveying path of the fabric 100. Figure 4 The length in the left-right direction. Therefore, it is possible to achieve miniaturization of the device and space-saving device installation.

[0165] Furthermore, as mentioned above, with in Figure 4 The combination of drying sections 8 along the vertical conveying path further enables the miniaturization of the device and space-saving design.

[0166] 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.

A method for processing fabric, characterized in that, The fabric is a fabric colored with pigments and has the following characteristics: A liquid jetting process involves jetting liquid from a jetting nozzle orifice of a liquid jetting section having at least one nozzle onto a fabric, causing the liquid to collide. The nozzle has the jetting nozzle orifice and a liquid inlet serving as an inlet for the liquid to flow into the jetting nozzle orifice. The liquid is water. The vibration imparting process imparts vibration to the fabric after the liquid spraying process. In this process, a vibration imparting part, which includes a contact member and a vibration generating source, imparts vibration to the fabric via protrusions. The contact member has a plate-shaped or block-shaped base and a plurality of protrusions that protrude from the base and abut against the fabric. The vibration generating source imparts vibration to the contact member. The contact member is provided with a pair of contact members arranged in the thickness direction of the fabric across the fabric's transport path. The protrusions protrude from the base toward the fabric's transport path. The protrusions of one of the contact members are staggered with the protrusions of the other contact member to form an interlaced configuration. In this vibration imparting process, the fabric is vibrated on both sides in the thickness direction of the fabric. The fabric, deformed by the protrusions, can simultaneously and repeatedly perform a striking action caused by collision with the base and a curling action with the ends of the protrusions as fulcrums. When the nozzle orifice diameter of the jet nozzle is set to d and the diameter of the liquid inlet is set to D, It satisfies 0.01mm≤d≤0.30mm and 5≤D / d≤150. The units for d and D are mm.

2. The processing method according to claim 1, characterized in that, In the liquid spraying process, one side of the fabric is supported by a support roller, and the liquid collides with the other side of the fabric.

3. The processing method according to claim 1, characterized in that, A liquid removal process is provided between the liquid spraying process and the vibration imparting process to remove the liquid adhering to or impregnating the fabric.

4. The processing method according to claim 3, characterized in that, In the liquid removal process, the liquid is removed by bringing the surface of the fabric that is in contact with the liquid into contact with a heated roller.

5. A fabric processing apparatus, characterized in that, The fabric is a dyed fabric, possessing the following characteristics: The conveyor department transports fabrics. A liquid jetting unit includes at least one nozzle having a jetting nozzle orifice and a liquid flow inlet serving as an inlet for the jetting nozzle orifice. Liquid, which is water, is jetted from the jetting nozzle orifice onto a fabric and agitated. A vibration-imposing unit imparts vibration to the fabric conveyed by the conveying unit after the liquid collides with the fabric. The vibration-imposing unit includes an abutting member and a vibration-generating source, and imparts vibration to the fabric via protrusions. The abutting member has a plate-shaped or block-shaped base and a plurality of protrusions that protrude from the base and abut against the fabric. The vibration-generating source imparts vibration to the abutting member. The abutting member is provided with a pair of protrusions that are separated from the conveying path of the fabric in the thickness direction. The protrusions protrude from the base toward the conveying path of the fabric. The protrusions of one of the abutting members are staggered with the protrusions of the other abutting member to form an interlaced configuration. The vibration-imposing unit imparts vibration to the fabric on both sides in the thickness direction of the fabric. The fabric deformed by the protrusions can simultaneously and repeatedly perform a striking action caused by colliding with the base and a curling action with the end of the protrusion as a fulcrum. When the nozzle orifice diameter of the jet nozzle is set to d and the diameter of the liquid inlet is set to D, It satisfies 0.01mm≤d≤0.30mm and 5≤D / d≤150. The units for d and D are mm.
