Description

  The present invention relates to a method for printing on a woolen fabric, in which a composite pattern in which a printing pattern and a concavo-convex pattern are synchronized is depicted on the surface of the woolen fabric.

  The ultrasonic concavo-convex pattern drawing method that draws the concavo-convex pattern on the fluff layer by applying pressure to the fluff layer made of hot-melt fiber and applying ultrasonic vibration and heating and melting the floating fiber made of hot-melt fiber. Known (for example, see Patent Documents 1 and 2). A laser beam concavo-convex pattern rendering method is known in which a laser beam is partially irradiated onto a fleece fabric made of a heat-meltable fiber, and the raised fiber is partially heated and melted to form a recess, thereby rendering an uneven pattern on the fluff layer. (See, for example, Patent Documents 3, 4, and 5). As a woolen cloth printing method for drawing a composite pattern in which a printing pattern and an uneven pattern are synchronized on the fabric surface, there is a discharging uneven printing method for printing a discharging agent containing a non-exhaust dye on the fluff layer of a woolen fabric. It is known (see, for example, Patent Document 6). A photosensitive heat-generating substance is printed on the fuzzy layer made of heat-meltable fiber and irradiated with near-infrared rays, and the floating fiber that becomes the heat-meltable fiber is heated and melted through the light-sensitive heat-generating substance, thereby forming a concavo-convex pattern on the fuzzy layer. A method for drawing a near-infrared concavo-convex pattern for drawing is known (see, for example, Patent Documents 7, 8, and 9).

  In the ultrasonic uneven pattern drawing method and laser beam uneven pattern drawing method, the patterns that make up the pattern cannot be color-coded in various ways, and ultrasonic waves and laser beams are partially applied along the pattern of the woolen fabric on which the printing pattern is drawn in advance. Even if it is possible to form a recess by thermally melting the floating fiber of the pattern at the irradiated spot and forming a recess, a special irradiation spot selection device for partially irradiating ultrasonic waves or laser beams is required. In addition, it is difficult to accurately synchronize ultrasonic waves or laser beams with a printed pattern, and even if a recess can be formed, a post-treatment is required to dissolve and remove the melt of floating fibers adhering to the recess. It is difficult to do.

  In the concavo-convex printing method, it is not possible to apply the raised fibers of the base fabric and the fluff layer to the same quality of the hairy fabric, and even if the base fabric is constituted by non-fibrous fibers that are not affected by the extractant. In addition, since even the floating fibers constituting the base fabric are also removed by removal from the fluff layer, the base fabric exposed in the recesses becomes fragile, and the recesses in which the base fabrics are removed and the projections that are not removed are removed. There is a difference in density of the fiber density with the part, the base fabric is easily worn in the concave part, and it is difficult to obtain a concavo-convex printed woolen cloth that is stable in strength.

In the near-infrared concavo-convex pattern drawing method, near-infrared rays are irradiated to the fuzz layer printed with a color-coded pattern using a photosensitive exothermic printing paste containing a photosensitive exothermic substance and a colored printing paste containing a coloring component such as a dye or pigment. As a result, it is possible to draw a composite pattern in which the printed pattern and the uneven pattern are synchronized. However, graphite and carbon black used as the photosensitive heating material are integrated with the melt of the floating fiber and fixed to the recess. The texture of the blanket is impaired, and the beauty is also impaired.
For this reason, as in the case of the ultrasonic uneven pattern drawing method and the laser beam uneven pattern drawing method, post-processing is required to dissolve and remove the photosensitive exothermic material fixed to the concave portion together with the melt of the floating fiber. .

Then, this invention sets it as the 1st objective to irradiate and draw a concavo-convex pattern on the surface of a woolen cloth, without using an irradiation location selection apparatus.
The second object of the present invention is to change the depth of the concave portion of the concavo-convex pattern drawn by the laser beam on the surface of the hairy fabric, and to obtain a hairy fabric rich in stereoscopic effect.
A third object of the present invention is to render a concavo-convex pattern synchronized with a printing pattern on the surface of a hairy fabric with a laser beam.
A fourth object of the present invention is to depict a composite pattern of a printing pattern and a concavo-convex pattern on the surface of a woolen fabric.

Printing Yes blanket 帛 according to the present invention may be brushed fabric to form a fluff layer 41 by raising the base fabric 45.

In the present invention, a printing pattern color-coded by the printing paste is drawn on the fluff layer, and at the same time, a laser beam is irradiated and the raised fiber is heated and deformed. In this case, in the printing portion 42 of the printing paste, the raised fiber is hardly deformed because it is covered with the printing paste, and the raised fiber is not easily heated and deformed because the laser beam is blocked by the printing paste. On the other hand, in the unprinted portion 43 of the printing paste, the raised fiber is not subjected to the shape holding action or the laser beam shielding action by the printing paste.
For this reason, the printing portion 42 colored in the printing paste and the unprinted printing portion 43 not colored are not only color-coded by the printing paste, but also distinguished by the difference in the degree of heating deformation of the floating fiber by the laser beam. As a result, the shape 47 between the printed portion 42 and the unprinted portion 43 becomes sharp.
The stamped part (pattern) 42 and the unprinted part (ground pattern) 43 are distinguished not only by the difference in color but also by the difference in the degree of heating deformation of the raised fibers, unlike the conventional printed fabric. The textile printing pattern does not disappear even if it is temporarily discolored, and a durable textile fabric can be obtained.

  The difference in the degree of heat deformation of the raised fiber between the pattern (printed portion 42) and the ground pattern (unprinted portion 43) does not depend on whether or not the laser beam is irradiated, but depends on the presence or absence of printing paste. Therefore, there is no need for an irradiation point selection device for irradiating a specific point (unprinted portion 43) with a laser beam.

  The fusible component of printing paste includes gum arabic, guar gum, locust bean gum, polyvinyl alcohol, sodium alginate, methylcellulose, carboxymethylcellulose soda salt (CMC), polyacrylic acid, which can form a printed coating that blocks the laser beam. Water-soluble resins such as sodium, polysaccharides and starch, water-dispersible resins such as natural latex and emulsion resins, clayey minerals having water-dispersibility such as bentonite, kaolin and clay, and vaporization / evaporation upon receiving laser beams, laser beams Water, fatty acid sodium salt, alkyl sulfate sodium salt, sodium dodecylbenzenesulfonate, sodium alkylbenzenesulfonate, sodium alkylnaphthalenesulfonate Surfactant such as salt, polyoxyethylene alkyl ether, sorbitan acid ester, glycerin fatty acid ester, methanol, ethanol, isobutylene alcohol, isopropyl alcohol, diethylene glycol, dipropylene glycol, polyethylene glycol, thioglycol, triethylene glycol, triethylene glycol Water-soluble organic solvents such as monomethyl ether and funnel oil are used.

In the printing part of printing paste that uses liquid such as water or alcohol as the fusible component, the degree of cooling action on the floating fiber varies depending on the amount of adhesion, and as the liquid evaporates, evaporates or volatilizes. The degree of cooling action changes.
In contrast, in the printing portion of a printing paste having a film-forming substance that forms a dry coating film such as a water-soluble resin as a fusible component, the vaporization / evaporation / evaporation of water or solvent contained in the printing paste Even if the fusing function changes with volatilization, the printing coating film is not completely lost, and the laser beam is blocked by the printing coating film, so that the thermal deformation of the floating fiber due to the laser beam is suppressed.
Therefore, if the printing paste is printed on the fluff layer 41 by partially changing any one of the fusing prevention component contained in the printing paste, the content of the fusing prevention component, and the printing amount of the printing paste, the depth is increased. Can be formed.
For example, if a printing paste containing a film-forming substance as a fusible component is printed thickly to suppress thermal deformation of the floating fiber, the printing portion 42a is thinly printed with a printing paste having a high liquid content. The convex part 50 which protruded relative to the parts 42b and 42c is formed.
Since the printing paste contains coloring components such as dyes and pigments, the convex portions 40, 50 (42a) and the concave portions 46, 46a, 46b, 46c) are color-coded by the printing paste, respectively. Then, the printing paste is partitioned by uneven steps at the time of printing paste printing (47a, 47b, 47c, 47).
Therefore, according to the present invention, various concave and convex portions 46a, 46b, and 46c having various depths and various 40 and 50 (42a) depict sharp and colorful uneven patterns, and have a three-dimensional impression. A blanket is obtained.

When a part of the surface of the fluff layer including the printed portion 42 printed with the printing paste and the unprinted portion 43 not printed with the printing paste is irradiated with a laser beam, the irradiated portion The concave / convex pattern by the concave portions 46 and the convex portions 40 at the non-irradiated portions is depicted.
On the other hand, in the printing portions (42a, 42b, 42c) of the printing paste, the concavo-convex pattern formed by the convex portions 50 and the concave portions 46 is drawn along the printing pattern of the printing paste at the laser beam irradiated portions as described above.
Since the coloring component is blended in the printing paste, the printing patterns (42a, 42b, 42c) color-coded by the printing paste are drawn separately from the uneven pattern.
Thus, when using the irradiation location selection device for irradiating a specific location with a laser beam, it is possible to draw a composite pattern in which the uneven pattern with the laser beam and the printing pattern with the printing paste are combined.

In the fluff layer in which the liquid adheres and is in a wet state, the liquid forms a thin film on the surface of the floating fiber, and it touches the molten melt of the floating fiber that receives heat from the laser beam and volatilizes (evaporates). When it does, it takes away the heat of vaporization and hinders the enlargement of the melt.
At the same time, since the liquid is a substance different from the fiber polymer, it is interposed as a release agent between the melts of the adjacent floating fibers and prevents the melts from coming into contact with each other and becoming enlarged.
For this reason, even if the floating fiber is thermally melted at the laser beam irradiation location, a finely divided molten mass is formed, and the molten mass is not large enough to stimulate the skin.
Therefore, the printing portion 42c of the printing paste using a liquid such as water or alcohol as the fusible component is more in comparison with the printing portions 42a and 42b of the printing paste using the film-forming substance such as water-soluble resin as the fusible component. The melted mass 52 having a large floating fiber is formed, but the melted mass 52 does not become larger than the maximum dimension (Q) exceeding 400 μm, and becomes a fine granular molten mass. The feeling of 41 is not impaired.

Therefore, when a deep concave portion 46c (46) is formed by irradiating the unprinted portion 43 of the printing paste with a laser beam, the printing portions 42a, 42b, 42c of the printing paste are used without using a printing screen or a printing roll. It is advisable to apply a fusing-proof liquid such as water or alcohol to the entire fluff layer containing.
For this purpose, prior to printing the printing paste, the fleece fabric may be immersed in the anti-melting liquid, and the anti-melting liquid may be applied to the entire fluff layer including the printing portions 42a, 42b and 42c of the printing paste. In addition, after printing the printing paste, an anti-fusing liquid may be applied to the entire fluff layer including the printing portions 42a, 42b, and 42c of the printing paste.
In order to apply the anti-melting liquid to the entire fluff layer after printing the printing paste, the anti-melting liquid may be applied to the entire surface of the fluff layer by spraying or the like. It is also possible to apply a fusible liquid to the cloth 45) and ooze out the fusible liquid from the back surface to the entire fluff layer.

When applying a fusing-proof liquid to the entire fluff layer after printing the printing paste, in order to avoid bleeding from the printing paste when printing, the printing paste is prepared mainly with a film-forming substance and printed. The paste printing film is dried or semi-dried to suppress fluidity, and then an anti-fusible liquid is applied. The dried or semi-dried printing paste printing film is again wetted and then irradiated with a laser beam. In order to avoid exudation of the printing paste due to the fusible liquid during printing, printing with a water repellent such as a wax-based water repellent, a silicone resin-based water repellent, or a fluorine resin-based water repellent. It is good to mix with glue.
It should be noted that several types of printing paste can be printed without leaving the unprinted portion 43, and the entire surface of the fluff layer 41 can be covered with a printing coating film of the printing paste, in which case no anti-fusible liquid is applied.

When the thickness (H) of the fluff layer is 2 mm or less, the unprinted portion 43 of the printing paste is heated by the laser beam to form the recess 46c (46). The melt of a large number of matching raised fibers moves without being free to touch and forms a large molten mass, moves so as to be attracted to the floated fibers that are thermally contracted, adheres to the base fabric 45, and forms a printed pattern. A recess 46c (46) is formed which is recessed at 47c.
At the bottom of the valley of the recess 46c (46) formed as described above, the melt of the floating fiber forms a hemispherical molten mass 53 having a maximum dimension (R) of 1000 μm or less in close contact with the base fabric 45, and the bottom of the valley A fine convex portion 48 that is finely raised is formed.
The hemispherical molten mass 53 forms fine irregularities 48 and 49 along the structure of the base fabric 45.
Accordingly, the fine recesses 49 and the recesses 49 and the interval L between the protrusions 48 and 48 are less than 1000 μm.
And the unevenness | corrugation difference of the fine recessed part 49 and the convex part 48 is less than the space | interval L of the fine recessed part 49 and the recessed part 49 and the convex part 48, and the convex part 48, and it is on the surface of the hemispherical molten lump 53. Are formed with finer irregularities than those fine concave portions 49 and convex portions 48.

By the way, the fiber bulk density of a fluff layer of a normal woolen fabric generally used as an interior material such as a moquette or carpet is generally about 0.1 g / cm ³ . For example, the pile layer (fluff layer) used for rugs such as Wilton carpets and tufted carpets, and the fabric weight of the pile fabric of 10 mm thick (pile length) is around 1000 g / m ² , and it is used for chair upholstery. The weight of the fluff layer of the moquette having a pile layer thickness of 4 mm is around 400 g / m ² .
The pile layer is formed assuming that the specific amount of pile fibers (floating fibers) of the conventional pile fabric is 1, and the fiber bulk density of the pile layer is assumed to be 0.1 g / cm ³ . When it is assumed that a film can be formed by heat-melting the pile fiber, the thickness of the film formed by the pile fiber of the pile layer having a basis weight of 1000 g / m ² is calculated to be 1000 μm (1 mm), and the basis weight is 400 g. The thickness of the film formed by the pile fiber of the pile layer of / m ² is 400 μm (0.4 mm).
As is clear from this, in the present invention, “the thickness of the fluff layer 41 is 2 mm or less” means that the calculated film thickness that can be formed by thermally melting the fluff layer 41 is 200 μm or less. Means.
However, even if the fluff layer 41 is actually melted by heat, the melt of the floating fibers does not form a film having a uniform thickness, but by the surface tension acting on the heat-melted material having fluidity, The floated fiber melt becomes a molten lump and moves so as to be attracted to the base fabric 45 by the heat shrinking action of the floated fiber during the formation process.

In that case, the melt of the floating fiber moves so as to be attracted to the base fabric 45 instantaneously without touching and enlargement, and becomes a hemispherical molten mass 53 having a maximum dimension (R) of 1000 μm or less. In order to form the fine irregularities 48 and 49 along the structure of the base fabric 45 on the bottom face of the concave portions 46c and 46, the thickness of the fluff layer 41 (H ) Should be as thin as possible.
Further, the melt of the floating fiber is fused to the base fabric 45 to form fine convex portions 48 on the bottom surfaces of the concave portions 46c and 46, and further fine irregularities are formed on the surface of the fine convex portions 48. In order to be formed, the single fiber fineness of the floating fiber 44 is preferably 5 dtex or less, more preferably 3 dtex or less.

In the concave portions 46c and 46 where the floating fibers are melted by heat and fused to the base fabric 45, the molten resin layer in which the hemispherical molten mass 53 is interrupted along the tissue structure of the base fabric, that is, fine concave portions 49 and the concave portion 49, and the molten resin layer in which the convex portion 48 and the convex portion 48 are less than 1000 μm and generally continues at an interval L of about 300 μm to 700 μm, and the unevenness difference between the fine convex portion 48 and the concave portion 49 is very slight. It is formed.
In the molten resin layer on the bottom of the valleys of the recesses 46c and 46, a ground pattern is drawn along the outline of the tissue structure of the base fabric 45 so as to be embossed by the fine irregularities (48 and 49).

The hemispherical molten mass 53 formed by the fluff layer 41 corresponding to the amount of resin of the film having a thickness of 200 μm or less is particularly large so that it can be seen even if the molten holes and melts formed into a film having a thickness of 200 μm or less can be seen. It is not a thing but it forms the convex part 48 of the rounded fine hemispherical curved surface, Therefore The ground pattern drawn on the valley bottom face of the recessed part 46c * 46 becomes a satin finish.
The fine convex portion 48 has a gentle hemispherical curved surface, so there is little frictional resistance, and it is part of the fiber that continues inside the base fabric, and deeply roots inside the base fabric. Therefore, even if the bottom surfaces of the recesses 46c and 46 are rubbed, they will not fall off.
Further, since the valley bottom surfaces of the concave portions 46c and 46 are covered with the convex portion 48 of the hemispherical curved surface that follows the discontinuity, the base cloth 45 is not directly rubbed.
And even if the deep recessed part 46c * 46 is formed in the fluff layer 41, the recessed part 46 is not formed by deform | transforming the base fabric 45, but only the fluff layer is formed by heat melting. Yes, the base fabric itself 45 stops its original shape.
Therefore, by drawing the uneven pattern on the fluff layer, the physical strength such as the shape stability and tensile strength of the base fabric 45 is not impaired. On the contrary, the base fabric is formed by the convex portion 48 of the hemispherical curved surface that is interrupted. Since the coating is protected, the wear resistance of the bristle fabric at the bottom of the valleys of the recesses 46c and 46 is improved.
In addition, according to the present invention, the melt of the floating fiber forms a fine textured pattern fused to the base fabric as a fine hemispherical melt mass 53, so that the melt is removed by dissolution. No finishing process is required.

As the woolen fabric, felt, raised fabric, chenille woven fabric, moquette, benjin, woven pile fabric such as cauldron and knitted pile fabric such as tricot and double raschel are applied.
Chenille woven fabric, woven pile fabric, and knitted pile fabric are composed of pile yarn (chenille yarn with pile protruding in chenille fabric) and ground yarn, the fluff layer is composed of pile yarn, and part of the pile yarn is ground yarn Together, it forms a base fabric, but the ground yarn does not form a fluff layer, and the root of the pile is surrounded by the ground yarn and locked to the base fabric.
For this reason, in the chenille woven fabric, the woven pile fabric, and the knitted pile fabric, when the pile (floating fiber) constituting the fluff layer forms a molten mass, the melt of the floating fiber is collected for each pile. The molten lump is formed and is easily scattered around the ground yarn, and as a result, the ground yarn constituting the base fabric is easily exposed between the scattered molten lump and the molten lump.

However, in the raised fabric in which the fluff layer is formed by raising the base fabric, some fibers of the yarn exposed on the surface of the base fabric are scraped to become floating fibers. However, it is difficult to form a molten lump that is piled up like a pile, and the formed molten lump is finer than the molten lump formed by the pile of the pile fabric, and is exposed on the surface of the base fabric. All the yarns are fixed, and a fine finely divided uneven film is formed on the surface of the valley bottom of the recess.
For this reason, when a raised fabric is used as the bristle fabric, the molten mass 53 constituting the convex portion 48 at the bottom of the concave portions 46c and 46 is fine and hardly scraped off.
And the space | interval L of the fine convex part 48 and the convex part 48 will be less than 500 micrometers, and the touch of the valley bottom face of the recessed part 46c * 46 will become good.
Therefore, it is desirable to use a raised fabric as the hairy fabric to which the present invention is applied.

As described above, when a liquid such as water or alcohol is used as the anti-fusible component, the thermal melting of the floating fiber is hindered, but the thermal contraction of the floating fiber due to the thermal melting is not so hindered, and the recess 46b It is formed.
However, when a film-forming substance such as a water-soluble resin is used as an anti-fusible component, not only thermal melting of the floating fibers but also thermal shrinkage is hindered, and printing portions 42a and 42b are printed with printing paste. Only the tip portion of the protruding fiber protruding from the surface of the coating film is thermally melted to form a spherical molten mass 51 having a maximum dimension (P) of 200 μm or less, and the protruding fiber 50 is formed without thermal contraction of the protruding fiber. Alternatively, an extremely shallow recess 46a is formed.
As a result, a pattern due to the difference in appearance from the unprinted portion 43 due to the presence or absence of the slightly deformed spherical molten mass 51 is drawn.

Therefore, when printing three types of printing pastes, a printing paste having a high content of a film-forming substance, a printing paste having a low content of a film-forming substance, and a printing paste not containing a film-forming substance, In the non-irradiated portion (convex portion 40), the color of the printing portion 42a of the printing paste having a high content of the film-forming substance and the color of the printing portion 42b of the printing paste having the low content of the film-forming material A printing pattern color-coded into four colors, ie, the color of the printing portion 42c of the printing paste not containing the film-forming substance and the color of the unprinted portion 43 where the printing paste is not printed, is drawn.
On the other hand, the projecting portion 50 where the laser beam is blocked on the printing coating film (42a) of the printing paste having a high content of the film-forming substance and the floating fiber remains without being heated and deformed at the irradiated portion of the laser beam, The shallow part of the tip portion of the protruding fiber protruding from the printing coating film (42b) of the printing paste having a low content of the film-forming substance forms a spherical molten mass 51 having a maximum dimension (P) of 200 μm or less and is slightly recessed. A concave portion 46a, and a concave portion 46b that is depressed by forming a granular molten mass 52 of 400 μm or less without being obstructed by the printing paste (42c) that does not contain a film-forming substance and enlarging the melt of floating fibers; A concave / convex pattern divided into four stages is drawn: a concave portion 46c which is formed by forming the hemispherical molten mass 53 of the unprinted portion 43 directly exposed to the laser beam to form a hemispherical molten mass 53.
And even if the degree of discoloration varies depending on the degree of heat deformation of the floating fiber, the laser beam irradiated part (convex part 50 and concave parts 46a, 46b, 46c) and the laser beam non-irradiated part (convex part 40, 42a, 42b,. 42c), there is a considerable color difference.
For this reason, according to the present invention, it is possible to obtain a variety of bristle fabrics in which the printed pattern and the uneven pattern are combined, and the undulations and colors are partially changed finely.

The surface layer of the woven pile fabric and the knitted pile fabric is referred to as “pile layer” instead of “fluff layer”, and the fibers forming the surface layer are not referred to as “floating fiber” but “pile”. It is called “fiber” or “pile”.
In the present invention, a pile layer of a woven pile fabric or a knitted pile fabric is referred to as a “fluff layer”, and a “pile fiber” is referred to as a “floating fiber”. The fiber yarn constituting the surface of the raised fabric and the chenille fabric is not called a pile, but is called “fluff” or “raised” in the felt or the raised fabric, and is called “flower yarn” in the chenille fabric. This is because the pile layer, which is the surface layer of the woven pile fabric or the knitted pile fabric, and the fluff and napping, which are the surface layers of the felt, the raised fabric, and the chenille fabric, are collectively referred to.
However, brushed fabrics and chenille fabrics are similar in appearance to pile fabrics such as moquettes and coal heavens, and they are sometimes referred to as “pile fabrics” and constitute their surfaces. Since the fiber yarn is sometimes referred to as “pile”, the “fluff layer” referred to in the present invention can be referred to as “pile layer”, and the “floating fiber” referred to in the present invention is referred to as “pile”. In other words.

  In the present invention, the “texture structure of the base fabric” refers to a nonwoven fabric-like entangled structure in which the fibers in the felt continue from the raised fibers of the fluff layer in a felt, or a woolen fabric formed by raising a knitted fabric as a base fabric. Warp yarns constituting the woven fabric that is the base fabric in the knitted yarn needle loops and sinker loops constituting the knitted fabric that is the base fabric, the stitches that constitute the insert yarn, and the hair fabrics that are raised using the woven fabric as the base fabric In the case of a pile fabric or pile knitted fabric, it means a texture or stitch in which a ground fabric or a pile yarn constituting a base fabric locking the pile is entangled.

As the floating fiber, a heat-melting synthetic fiber such as nylon, vinylon, polypropylene fiber, acrylic fiber, or polyester fiber is used.
If the fiber density (bulk density) of the fluff layer 41 (projections 40, 50) of the printed woolen fabric is too high (dense), the melt of adjacent floating fibers come into contact with each other to form a large molten mass, and the melt The valley bottoms of the recesses 46 and 46c are painted as if they were glazed with an object, so that the structure of the base fabric 45 is not exposed, and the melt is hardened on the valley bottom, and the texture of the woolen fabric is impaired.
In order to avoid such an inconvenience, the fluff layer (H) should be thin, and the fiber density of the fluff layer should be 0.15 g / cm ³ or less.
The lower limit of the fiber density of the fluff layer 41 is appropriately set to such an extent that the base fabric 45 is not exposed from between the raised fibers 44 in the recesses 46 and 46c, but 0.05 g / in terms of wear resistance of the fluff layer 41. It is good to make it cm ³ or more.
Considering these points, the bulk density of the fluff layer (convex) 41 which constitutes the浮出fibers 0.05~0.15g / cm ^3, preferably a 0.08~0.12g / cm ³ 0 .About 1 g / cm ³ .
Printing of the anti-fusing agent on the fluff layer can be performed by hand drawing as well as by a printing apparatus such as a gravure roll, a rotary printing screen, a flat printing screen, and an inkjet nozzle.

The printing paste is prepared using a water-soluble resin and water as main materials.
The water-soluble resin and water can also be used as a fusible component.
Flame retardants such as ammonium polyphosphate, ammonium sulfamate, and guanidine sulfamate may be added to the printing paste as a fusible component.
Printing of the anti-fusing agent on the fluff layer can be performed by hand drawing as well as by a printing apparatus such as a gravure roll, a rotary printing screen, a flat printing screen, and an inkjet nozzle.

  In order to draw a concavo-convex pattern by locally irradiating a part of the surface of the fluff layer including the printed portion 42 printed with the printing paste and the unprinted portion 43 not printed with the printing paste, The laser beam 11 emitted from the laser beam oscillator and traveling straight is reflected on the first mirror surface 13, and the reflected laser beam 19 is reflected again on the second mirror surface 14 to irradiate the surface of the fluff layer 41. The mirror surface 13 and the second mirror surface 14 are oscillated to change the reflection angle (α · β) of the laser beam on the mirror surface (13, 14) to match the irradiation position 21 of the laser beam to the required portion on the fabric surface.

While moving the woolen fabric intermittently in any direction, the first mirror surface 13 is swung to change the reflection angle α in the stationary state, or the second mirror surface 14 is swung to reflect the reflection angle β. The laser beam 11 can be irradiated to the entire surface of the fluff layer 41 on which the printing paste has been printed by scanning the laser beam (20) in a straight line on the background of the woolen fabric. The laser beam 11 can also be irradiated locally in order to form the recess 46 in the unprinted portion 43 where no paste is printed.
When both the reflection angle α of the first mirror surface 13 and the reflection angle β of the second mirror surface 14 are changed, the entire surface of the fluff layer 41 of the woolen fabric fixed without being moved, or locally The fluff layer 41 can be irradiated with a laser beam, and even if the woolen fabric is continuously moving, the rotation speed of either the first mirror surface 13 or the second mirror surface 14 depends on the moving speed of the hair fabric. By adjusting the speed (α · β), the laser beam 11 can be irradiated on the whole or part of the hairy fabric in the same manner as when the hairy fabric is moved intermittently.
For this reason, according to the present invention, by irradiating the surface of the fluff layer 41 printed with the printing paste with the laser beam 11 locally, a composite pattern in which the printing pattern by the printing paste and the unevenness by the laser beam are combined is drawn. I can do it.

In that case, since the position of the oscillation device or the mirror surface is not moved in order to match the irradiation position 21 of the laser beam, the laser beam of the required amount of heat is accurately irradiated to the required portion of the surface of the fluff layer, and the required displacement is not caused. A concave / convex pattern can be accurately depicted at a position by a laser beam.
When the first mirror surface 13 or the second mirror surface 14 is swung to irradiate the fluff layer 41 with a laser beam in a straight line, the molten mass 51 (52, 53) of the floating fiber is formed along the scanning line of the laser beam 20. In the case where the base fabric 45 forms a woven / knitted structure, as shown by dotted lines, the molten mass 53 is arranged along the weave or stitch and forms a part of the weave or stitch. Even if the base fabric 45 is a non-woven fabric, the molten mass 53 does not give an impression of a texture or stitch, and does not give an impression of the melt of floated fibers. A concavo-convex pattern-printed woolen fabric is obtained as if it were woven or knitted.
The uneven pattern is not limited to a pattern or a figure, but may be a symbol or a character.

  FIG. 2 illustrates a laser beam oscillation device. The laser beam 11 is emitted from the laser oscillation device, travels straight through the focus correction lens 12 to the first mirror surface 13, and is reflected by the first mirror surface 13 and the 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 surface of the fluff layer can be locally irradiated by adjusting the amount of the laser beam emitted from the laser beam oscillator in the laser beam oscillator.
Further, the printing paste is printed on the fuzz layer 41 without changing the difference in the fusing component, the content of the fusing component, and the printing amount of the printing paste, and the amount of the laser beam emitted from the laser beam oscillation device is oscillated by the laser beam. By changing the amount of the laser beam in the apparatus, the depth of the recesses 46a, 46b, 46c, 46 can be adjusted to obtain a printed woolen fabric rich in appearance changes.

Through the dyeing process, the weight per unit area is 484 g / m ² , and the fiber density of the fluff layer is 0. Finished into a tricot warp knitted pile fabric of .11 g / cm ³ .

  Next, a pigment comprising 65 parts by weight of a water-soluble resin (Nikka Chemical Co., Ltd., Nikka gum C-60), 1 part by weight of a disperse dye (Disperse Blue SSL-5, manufactured by Kyojin Sangyo Co., Ltd.), and 34 parts by weight of tap water A blended printing paste is prepared, and a printing pattern is printed on the surface of the fluff layer of the tricot warp knitted pile fabric using a 100 mesh flat printing screen and an 8φ stainless steel squeegee.

  Next, a concavo-convex pattern drawn by a straight line arranged in parallel with an interval of 0.5 mm by a digital image is prepared separately from the printing pattern of the printing screen, and a CO2 laser irradiation device (G-100 manufactured by coherent, output condition 5 to 80 W, A laser beam emitted from 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 is reflected on the first mirror surface, and the reflected laser beam is reflected again on the second mirror surface. Reflecting, swinging the first mirror surface and the second mirror surface, irradiating the surface of the fabric with a laser beam, and irradiating the surface of the fluff layer of the tricot warp knitted pile fabric printed with the dye-containing paste, A hot-melt recess is formed on the surface of the fluff layer, and after reduction cleaning, it is passed through a pin tenter and dried. Projections and recesses are color-coded in synchronization with the printing pattern of the emission, to obtain a relief pattern printing tricot warp knitting pile fabric textile pattern and convex pattern are overlapped.

  In this concavo-convex pattern printed tricot warp knitted pile fabric, on the surface of the valley bottom of the concave portion, the molten mass forms fine irregularities along the structure of the ground yarn or pile yarn, and the fine concave portions, concave portions and convex portions are formed. The distance L between the convex part and the convex part is less than 500 μm and is generally fine at 100 to 300 μm, and the unevenness difference between the fine concave part and the convex part is good at around 300 μm. The printed pattern was sharply bordered as if printed, and a composite pattern in which the printed pattern and the concavo-convex pattern overlapped was drawn.
