Japanese Patent Publication No. 04-001114 (Japanese Patent Laid-Open No. 60-162880) Japanese Patent Publication No. 03-025544 (Japanese Patent Laid-Open No. 62-104964) Japanese Patent Publication No. 05-071697 (Japanese Patent Laid-Open No. 63-309666) JP 2002-371478 A JP 2002-201563 A JP 59-137564 A Japanese Utility Model Publication No. 03-018552 (Japanese Utility Model Publication No. 2-57993) Japanese Patent Publication No. 63-025108 (Japanese Patent Laid-Open No. 58-174676)

The above-mentioned prior art is a fabric by the unevenness difference between the concave part which is caused by heat shrinkage of the thermoplastic fiber with heat melting and the convex part which the non-heated part of the thermoplastic fiber which is not heated constitutes relatively. A pattern is to be drawn on the surface, and in the concave portion, a molten lump is formed in which the thermoplastic fiber is heated and melted and solidified, and the texture of the fabric surface becomes coarse due to the molten lump.
Of course, there is also a method in which the surface of the fabric is subjected to a brushing process, or a relaxation process is applied to apply vibration to the entire fabric to break it up, and the molten mass is subdivided.
However, if the finishing process is performed after drawing such a pattern, the production cost of the fabric is increased by that amount, and the fabric surface has an irregular fluffy and fatigued view. If the surface is subjected to hair conditioning treatment, the manufacturing cost is further increased.

  Therefore, the present invention irradiates the surface of the fabric with a laser beam without generating a large melted lump, heats and melts the exposed portion of the fiber exposed on the fabric surface, and flattens the fabric surface or changes the color tone of the fabric surface. The purpose is to finish the surface of the fabric without changing or drawing the design on the surface and increasing the manufacturing cost.

  That is, in the prior art based on ultrasonic vibration (Patent Documents 1 and 2), a device (horn) that transmits ultrasonic vibration to the thermoplastic fiber must be pressure-bonded to the fabric surface. In References 3 and 4), the thermoplastic fibers are temporarily joined by the printing paste, and the size of the molten mass cannot be controlled because the photosensitive exothermic material is in direct contact with the thermoplastic fibers. However, in the prior art using laser beams (Patent Documents 5, 6 and 7), the heating means of the thermoplastic fiber is an electromagnetic wave having no mass and does not force the contact between the fibers, and volatilizes (evaporates) at the irradiated part. ) When the heat dissipation means is applied, the heating temperature is controlled by the very limited details, and the heat dissipation means also functions as a release agent that keeps the fibers separated, and the molten mass is subdivided. With the knowledge that There has been completed.

Therefore, in the fabric surface finishing method according to the present invention, the liquid is attached to the surface of the fabric on which the thermoplastic fiber is exposed, and the surface of the thermoplastic fiber exposed to the laser beam is irradiated with the laser beam. The first characteristic is that the liquid is water .

  The second feature of the fabric surface finishing method according to the present invention is that, in addition to the first feature, a liquid is partially adhered to the fabric surface.

  A third feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first and second features, a laser beam is partially irradiated on the fabric surface to which the liquid is adhered. The exposed surface portion of some exposed thermoplastic fibers is heated and melted, and a pattern is drawn on the surface of the fabric depending on the presence or absence of the heat melting.

  The fourth feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first, second and third features, the liquid is soluble, dispersible or adsorbed in the liquid. It is in the point which is prepared to the mixed composition with the hydrophilic substance which shows property, and is made to adhere to the fabric surface.

  A fifth feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first, second, third and fourth features, the thermoplastic fiber has irregularities in the outline of its cross section, or The fiber is a modified cross-section fiber having a cavity inside the cross section.

  The sixth feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first, second, third, fourth and fifth features, the thermoplastic fiber comprises a dye, a pigment and a matte material. It is in the point which has either of an agent.

  A seventh feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first, second, third, fourth, fifth, and sixth features, the fabric has a raised fluff layer and a base. Brushed two-layer structure fabric consisting of a fabric layer, pile two-layer structure fabric consisting of a pile layer and a base fabric layer, two-layer structure fabric in which the front and back yarns are woven and knitted on the front and back, and the front and back fabrics connected It is the point that it is the two-layer structure fabric of any one of the three-dimensional two-layer structure fabric connected and integrated by the yarn.

  The eighth feature of the fabric surface finishing method according to the present invention is that, in addition to any of the first, second, third, fourth, fifth, sixth and seventh features, the laser beam is emitted from the laser beam oscillator. The reflected laser beam is reflected by the first mirror surface that is driven to oscillate and rotate, and the reflected laser beam is driven to oscillate and rotate, and the length direction of the rotation center axis is the length of the rotation center axis of the first mirror surface. The second mirror surface that is 90 degrees different from the vertical direction is reflected again to irradiate the fabric surface, and the first mirror surface and the second mirror surface are swung to change the reflection angle of the laser beam on the mirror surface, thereby changing the required position on the fabric surface. The point is to match the laser beam irradiation position.

  The woolen fabric according to the present invention includes an electrostatic flocking fabric, a felt, a raised fabric, a chenille woven fabric, a moquette, a bend, a woven pile fabric such as cauldron, a surface raised layer and a back surface such as a knitted pile fabric such as tricot and double raschel. On the hair pile surface of the hair fabric that forms a two-layer structure with the base fabric layer, the fluff pile fibers are melted to form a granular molten mass, and the concave portions where the fluff pile fibers are melted and depressed are formed. There are many granular molten masses that are engraved and melted and solidified by melting the fluff pile fibers on the wall surface of the concave portion rather than the bottom of the concave portion, and the maximum size of the granular molten mass is 300 μm or less This is the first feature.

  A second feature of the woolen fabric according to the present invention is that, in addition to the first feature, the concave portion is long and continuously forms a groove having a groove width of 0.7 mm or less, and the granular molten mass is a groove. It is in the point scattered more in the groove wall surface than the bottom.

On the surface of the fabric in which the liquid adheres and is in a wet state, the liquid forms a thin film on the surface of the fiber, and touches the molten mass formed by the exposed portion of the surface of the thermoplastic fiber melted by receiving the laser beam. When volatilizing (evaporating), it takes away the heat of vaporization and prevents the molten mass from being enlarged, and since the liquid is a different substance from the fiber polymer, it is interposed as a release agent between the molten mass of adjacent fibers and the molten mass. This prevents the molten mass from touching each other to enlarge.
For this reason, the fabric surface exposed fiber is heated and melted without forming a large melted lump at the laser beam irradiation site, and changes in the appearance of the fabric surface are caused.

  Mixture composition of liquid with hydrophilic substance that is soluble, dispersible, or adsorbable with respect to the liquid in order to make the liquid easy to conform to the fiber and to form a film with the liquid on the fiber surface. It is recommended that the liquid be made sticky.

The change in appearance is manifested on the fabric surface as follows.
(1) When a liquid is attached to the entire surface of the fabric and the entire surface of the fabric is irradiated with a laser beam, the reflection of the light changes with the change in the shape of the surface exposed fibers, resulting in changes in gloss and tone. As a result, the fabric surface fluff is suppressed and the fabric surface is finished smoothly.
(2) When the liquid is partially attached to the fabric surface and the laser beam is applied to the attachment site, or when the liquid is applied to the entire surface of the fabric and the laser beam is partially applied, the surface exposed fiber A pattern is drawn on the surface of the fabric depending on the presence or absence of heat melting.

  If the thermoplastic fiber is irregular in the cross-sectional profile, or if it has a deformed cross-section fiber with a cavity inside the cross-section, the melt fills the part that appears as a recess or cavity in the cross-section, and the surface area A small spherical molten mass will be formed, but the molten mass will become smaller as the melt fills the recesses and cavities, and it will not feel the touch, and from the shape with irregularities and cavities on the surface to the surface Since the fibers are deformed into a spherical molten mass without irregularities and cavities and the gloss changes, the appearance of the fabric can be greatly changed.

  If the thermoplastic fibers have a foreign material that is different from dyes, pigments, matting agents, and other fiber polymers, they will appear on the surface of the molten mass with a spherical shape and less diffuse reflection of light. The melted portion becomes dark and the pattern that appears when the laser beam is irradiated locally becomes clear.

  The fabric is a raised two-layer structure fabric comprising a raised fluff layer and a base fabric layer, a pile two-layer structure fabric comprising a pile layer and a base fabric layer, and a two-layer structure fabric in which the front and back yarns are woven and knitted on the front and back In the case of a two-layer structure fabric such as a three-dimensional two-layer structure fabric in which the front fabric and the back fabric are connected and integrated by a connecting yarn, the heat of the fuzz, pile, front yarn, or front fabric constituting the upper layer Even if the plastic fiber is heated and melted greatly, the physical strength of the fabric can be maintained by the base fabric, backing yarn, or backing fabric that constitutes the lower layer. A three-dimensional concavo-convex pattern due to a recess having a large difference can be drawn on the fabric surface.

According to the present invention, the melt of the thermoplastic fiber adheres to the thermoplastic fiber so that the wax dripping from the drowned candle onto the water surface is solidified by contact with water in the recess formed by heating and melting the surface-exposed fiber. It touches the liquid that is in contact and solidifies in a granular form and adheres to the wall surface of the recess, making it difficult to intervene in the center of the recess.
For this reason, the laser beam is not interrupted by the melt interposed in the central portion (bottom portion) of the concave portion, and can deeply enter the fabric and form a deep concave portion to reach the back surface.
Therefore, two layers of a surface raised layer and a back surface base fabric layer such as electrostatic flocked fabric, felt, brushed fabric, chenille fabric, moquette, benjin, woven pile fabric such as coal heaven, knitted pile fabric such as tricot and double raschel, etc. When the present invention is applied to a hairy fabric having a structure, and grooves are engraved on the surface of the hairy pile, the groove wall surfaces facing each other are inclined toward the groove bottom, and the grooves are generally V-shaped in cross section. The grooves can be engraved on the surface of the bristle pile so that granular molten masses with a maximum dimension of 300 μm or less in which the fluff pile fibers are melted are scattered on the groove wall surface.
In addition, such a granular molten mass having a maximum dimension of 300 μm or less does not give a touch as if it touched a hard foreign object even if it is touched with a fingertip. Can be obtained.

  By irradiating a laser beam, a through hole or notch can be attached to the fabric, and a melt of the thermoplastic fiber is fixed to the periphery of the through hole or notch. According to the present invention, the thermoplastic fiber is melted. Since the object becomes a fine granular molten mass with a maximum dimension of 300 μm or less, there is no foreign object feeling that hard foreign matter (melt) is fixed to the periphery of the through hole or notch, and the through hole or notch Since the thermoplastic fibers at the periphery of the material are fixed as a fine granular molten mass, the fabric does not unravel from the through-holes or the periphery of the cut.

  In the present invention, the laser beam emitted from the laser beam oscillation device and traveling straight is reflected on the first mirror surface, and the reflected laser beam is reflected again on the second mirror surface to irradiate the fabric surface. Swing the two mirror surfaces to change the reflection angle of the laser beam on the mirror surface to match the laser beam irradiation position to the required location on the fabric surface, and move the position of the oscillation device and mirror surface to match the laser beam irradiation position Therefore, it is possible to accurately irradiate a required portion of the fabric surface with a laser beam having a required amount of heat and accurately draw a pattern with a laser beam at a required position without causing a pattern shift.

FIG. 1 illustrates a laser beam oscillation device. A laser beam 11 is emitted from the laser oscillation device, travels straight through a focus correction lens 12 to a first mirror surface 13, and is reflected by a first mirror surface 13 and a second mirror surface 14. The fabric surface 15 is irradiated. The rotation center 16 of the first mirror surface 13 is set on the surface of the first mirror surface 13, and the laser beam 11 is irradiated onto the rotation center line (16) of the first mirror surface. Therefore, even if the first mirror surface 13 swings and rotates, the irradiation position 17 on the first mirror surface does not change.
The rotation center 18 of the second mirror surface is the surface of the second mirror surface 14 and is set at a position where the reflected light 19 of the laser beam on the first mirror surface 13 is irradiated.

Since the rotation center axis 16 of the first mirror surface and the rotation center axis 18 of the second mirror surface are different from each other by 90 degrees, the reflection angle of the laser beam on the first mirror surface becomes the oscillation rotation angle α of the first mirror surface. Even if it changes accordingly, the reflected light 19a, 19b, 19c, 19d of the laser beam at the first mirror surface is always re-reflected on the rotation center axis 18 of the second mirror surface, and the re-reflected light 20a, 20b, 20c. The irradiation positions 21a, 21b, and 21c on the fabric surface 15 of 20d move on a straight line X that is parallel to the rotation center axis 18 of the second mirror surface as the swinging rotation angle α of the first mirror surface changes.
On the other hand, when the second mirror surface 14 swings and rotates, the re-reflected light 20a, 20a ′, 20b ′ at the second mirror surface changes its direction according to the rotation angle β, and the irradiation position 21a. 21a ′ and 21b ′ move on a straight line Y parallel to the rotation center axis 16 of the first mirror surface.

For this reason, when the first mirror surface 13 and the second mirror surface 14 are driven to swing and rotate, the irradiation position 21 of the laser beam on the fabric surface 15 can be freely moved according to the rotation angle (α · β). .
Thus, when the irradiation position 21 on the fabric surface moves, the total length of the path of the laser beam 11 from the focus correction lens 12 to the irradiation position 21 changes.
Reference numeral 22 denotes an irradiation position 21 (21a, 21a ′, 21b ′, 21) from the focus correction lens 12 that changes depending on the displacement amount Δα of the rotation angle α of the first mirror surface 13 and the displacement amount Δβ of the rotation angle β of the second mirror surface 14. 21b... 21c...)) Is a distance calculation element that calculates the total length of the path of the laser beam 11 and receives the calculation information from the distance calculation element 22, the focus correction lens 12 is activated, and the focus of the laser beam is the fabric. It is adjusted to the required irradiation position 21 on the surface.

The liquid is applied to the fabric so that the liquid pick-up rate at the attachment site is 70 to 170%, generally 110 to 140%.
Water is recommended as the liquid adhering to the fabric surface.
Examples of hydrophilic substances that are soluble in water include substances that exhibit a flame-retardant effect such as ammonium polyphosphate, ammonium sulfamate, guanidine sulfamate, and starch, polyvinyl alcohol, sodium carboxymethyl cellulose ( CMC) or the like is preferably used.
As a hydrophilic substance exhibiting dispersibility to be blended in water, latex or emulsion resin containing a surfactant is used.
As the hydrophilic substance showing the adsorptivity to be mixed with water, clayey minerals such as bentonite, kaolin and clay are used.
The amount of these hydrophilic substances incorporated in water may be so small that the water is only slightly viscous.
However, when water is applied as a liquid to be applied to the fabric, it does not mean that the water must be applied as a mixed composition with a hydrophilic substance, but rather a mixed composition with a hydrophilic substance. It is desirable to apply only water as a liquid to the fabric, not as a product. This is also to save the work of post-treatment for eliminating the hydrophilic substance after the practice of the present invention.
Applying a hydrophilic substance to adjust the viscosity of the liquid is effective when the liquid is partially adhered to the fabric surface.

In order to partially adhere the liquid to the surface of the fabric, a printing screen, gravure roll, spray, or the like used for printing the printing paste may be used.
In that case, the amount of liquid adhesion can be changed partially by a printing screen, gravure roll, spray, etc., or the amount of liquid adhesion can be changed gently, so that the degree of melting of the thermoplastic fiber by the laser beam is partially increased. It is also possible to draw a pattern with irregularities and undulations on the fabric by changing the depth of the groove or by gently changing the depth of the groove formed by melting the thermoplastic fiber. .

  The fabric is an electrostatic flocking fabric, a felt, a raised fabric, a chenille fabric, a moquette, a beveled fabric, a woven pile fabric such as a corten, a knitted pile fabric such as a tricot or double raschel, etc. In a hairy fabric having a layered structure, it is preferable that the thickness of the raised layer by raised fluff or pile is 0.5 to 2.5 mm, and that moisture contained in the base fabric is easily transferred to the tip of the raised fiber when irradiated with a laser beam.

The fineness of the surface exposed fiber is 5 dtex or less, preferably 2 dtex or less.
As the thermoplastic fiber, nylon, vinylon, polypropylene fiber, acrylic fiber, polyester fiber, or the like is used.
In addition to these thermoplastic fibers, non-thermoplastic fibers such as rayon, cotton, and silk may be mixed on the fabric surface. In this case, the mixing ratio of the non-thermoplastic fibers is 30% by mass or less. To do.

  A raised fabric such as a raised fabric or a pile fabric may have a raised fluff or pile formed on the surface of the fabric in a striped or striped pattern or a checkered pattern.

Then, tricot a warp knitting pile fabric was immersed in water, and Shiboeki by mangle pickup rate as 130%, placing an endless belt with open width in a pin tenter, CO ₂ laser irradiation device (coherent Ltd. G-100, output condition 5 to 80 W, a beam diameter of 0.5 mm, a beam spot moving speed of 80 to 500 mm / second, an oscillation frequency of 1 kHz, and a focal length of 760 mm) are reflected on the first mirror surface, and the reflected laser beam is reflected on the first mirror surface. Reflected again at the two mirror surfaces, the first mirror surface and the second mirror surface are oscillated, the surface of the fabric is irradiated with a laser beam in a lattice shape, and the tip portion of the pile fiber is heated and melted. A tricot warp knitted pile fabric having a lattice pattern drawn as a 3 mm straight line was obtained.

[Example 2]
In a moquette loom, blended 20th yarn with 65% polyester fiber and 35% rayon is used as the ground warp yarn, blended yarn 30th yarn with 85% polyester fiber and 15% rayon is used as the ground warp yarn, 180 twists / m Moquette with a warp density of 142 / 10cm, weft density of 215 / 10cm, pile weight of 333g / m ² , and pile length of 2.4mm, woven with twisted 187dtex / 168F polyester multifilament processed yarn As in Example 1, the sample was immersed in water, the pick-up rate was set to 130%, the solution was squeezed with a mangle, placed on an endless belt while being spread with a pin tenter, and a CO ₂ laser irradiation device (G-made by Coherent, USA). 100, output condition 5-80W, beam diameter 0.5mm, beam spot moving speed 80-500m / Second, oscillation frequency 1 kHz, focal length 760 mm), the laser beam traveling straight and reflected at the first mirror surface is reflected again at the second mirror surface, and the first mirror surface and the second mirror surface are oscillated. Then, the surface of the fabric is irradiated with a laser beam in a lattice pattern, the tip portion of the pile fiber is heated and melted, and the heated and melted portion is generally a straight line having a width of 0.3 mm. A fabric was obtained.

[Comparative example]
A tricot warp knitted pile fabric in which a lattice pattern was drawn was obtained by irradiating the moquette woven in Example 2 in a lattice pattern in the same manner as in Example 2 without immersing it in water.

[Confirmation of effect]
The cross section of the laser beam irradiated portion of the moquette obtained in Example 2 and the comparative example was examined with a digital microscope (manufactured by Keyence Corporation, Digital HF microscope Vh-8000), and the irradiated portion was observed.

As shown in FIG. 2, the irradiation place of the moquette 23a of the second embodiment forms a groove 25a having a generally V-shaped cross section having a depth of about 2000 μm (2 mm) deep enough to reach the ground structure 28 of the moquette.
The molten mass 26a of the pile fiber becomes a granular melt having a maximum dimension of 200 μm or less on the inclined groove wall surface 19 of the groove 25a having a V-shaped cross section as shown in FIG. The granular melt is fixed for each pile, and is scattered finely in the depth direction of the groove 25a (the length direction of the pile). It was not recognized to be continuous.
When the part of the groove 25a was touched with a fingertip, a touch as if a hard foreign object had been touched was not felt.

As shown in FIG. 3, the irradiated portion of the moquette 23b of the comparative example is a groove having a generally flat cross-sectional shape in which the pile fiber 24 melts and sinks below the pile surface 30, and the pile fiber melt mass 26b accumulates at the bottom. A bottom surface 27 is formed, and a groove 25b having a generally U-shaped cross section having a depth of about 400 μm (0.4 mm) is formed.
The pile fiber melt mass 26b has a flat cross-sectional shape with a gap of about 50 μm (0.05 mm) in the laser beam scanning direction as shown in FIG. Becomes a belt-like melt of about 1000 μm (1.00 mm), and forms a groove bottom surface 27 having a width corresponding to the beam diameter (0.5 mm) of the laser beam and continues linearly in the scanning direction of the laser beam.
When the part of the groove 25b was touched with a fingertip, a certain touch as if touching a hard linear foreign object was felt.

In considering the difference in the shape of the grooves 25a and 25b in the example of the present invention and the comparative example, the melt of the pile fiber 24 in the example (so that the wax dripping on the water surface from the drowned candle touches the water and hardens) 26a) is in contact with the liquid adhering to the pile fiber, is fixed in the form of granular wall surfaces 29a and 29b that are solidified and face each other and are separated into left and right groove wall surfaces 29a and 29b that face the melt. However, since the laser beam does not intervene between the left and right groove wall surfaces 29a and 29b, the laser beam penetrates deeply into the pile layer 31 without being blocked by the melt (26a), and as a result, the deep V reaches a depth of the ground structure 28. It is considered that the letter-shaped groove 25a is formed.
On the other hand, in the comparative example, the pile fiber melt (26b) is not particularly cooled by the pile fiber 24, and the pile surface is fixed so that the wax dripping onto the pile surface is fixed in a flat shape. 30 is fixed in a strip shape having a generally flat cross section, which blocks the laser beam, so that the laser beam does not penetrate deeply into the pile layer 31 and a shallow U-shaped groove 25b having a flat groove bottom 27b is formed. It is done.
2 and 3 are enlarged and encircled by circles, which are micrographs of the groove wall surfaces of the moquettes of Example 2 and Comparative Example, respectively.
