Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile cloth mainly used as a rug.

[0002]

2. Description of the Related Art As one method of drawing a pattern on the surface of pile fabric such as moquette and tufted carpet, solubility in chemicals such as nylon and rayon, nylon and polyester fiber, general polyester fiber and modified polyester fiber Different colors of different color fiber materials 11.
One of the fiber materials 11 on the pile surface composed of the mixed spun yarn, the mixed fiber yarn, the core-sheath fiber yarn, etc.
Which does not dissolve the other fiber material 12 (hereinafter,
It is called an etchant. ) Is printed, and a single color of the fiber material 12 (hereinafter referred to as insoluble fiber) that remains without being dissolved in the etching agent at the printing position, and non-printing in which the etching agent is not printed A method is known in which a discharge pattern which is color-coded by the mixed color of the differently differently colored fiber materials 11 and 12 remaining in a place is drawn.

[0003]

According to this method, the insoluble fiber 12 remains as fluff on the surface at the printing position, and one of the fiber materials 11 (hereinafter referred to as soluble fiber) is dissolved in the etchant. Is hidden under the fluff of the insoluble fiber 12 and does not appear on the surface, so the insoluble fiber 1 appears on the surface.
Although the fluff of No. 2 has a single color, the surface of the imprinted portion has a coarser fiber density as much as the soluble fiber 11 is dissolved and removed. If the fluff of the fiber 12 does not stick out for a long time, the color of the soluble fiber 11 that should be hidden by the fluff of the insoluble fiber 12 can be seen through. The unpainted pattern that should be color-coded becomes unclear.

On the other hand, in the case of preparing an etching agent having a low viscosity by blending a penetrating agent for printing, it is possible to penetrate deeply into the pile layer, but at the same time, the discharging agent is discharged to the outside of the printing mold. Is easily exuded, and the outline of the discharge pattern becomes unclear.
Therefore, it is conceivable to increase the mixing ratio of the non-soluble fibers 12 constituting the pile yarn so that the fiber density on the surface of the printing portion does not become too coarse, but in that case, the color of the non-printing portion is also increased. Since the color of the insoluble fiber is largely controlled, the color distinction between the printed portion and the non-printed portion is insufficient, and a sharp discharge pattern cannot be obtained when molding.

Further, according to the conventional technique, a difference in hardness occurs due to a difference in fiber density between a printed portion and a non-printed portion, so that the pile surface is not finished as a plane.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention does not create a step on the pile surface due to the difference in fiber density between the printed portion and the non-printed portion of the discharging agent, and has a sharp discharge pattern on the die. It is something that I try to depict.

[0007]

The pile fabric according to the present invention comprises two kinds of fiber materials 11 having different solubilities for chemicals.
One of 12 is the sea component (11) and the other is the island component (12)
In the surface layer portion 15 which does not reach the lower layer portion 15 of the pile 16 which is composed of a plurality of composite synthetic fibers 13 having a sectional shape in which the island component (12) is partitioned into a plurality of sections by the sea component (11) , The pile 16
The sea component (1 of each of the plurality of composite synthetic fibers 13 constituting the
1) is characterized by having a pile 16 in which a surface layer portion 15 of each composite synthetic fiber 13 is composed of a plurality of fiber materials 12 of an island component (12) which appears after being dissolved and removed.

The second characteristic of the pile fabric according to the present invention is

It is divided into four or more compartments by the minute 11 , and the third characteristic is that the sea component 11 contains a pigment, preferably carbon black. In the pile fabric according to the present invention, one of the two kinds of fiber materials 11 and 12 having different solubilities for chemicals is the sea component (11) and the other is the island component (12), and the island component (12) is the sea component (11).
The corrosive agent and the island component (12) that dissolve the sea component (11) on the surface (15) of the pile 16 that is composed of a plurality of composite synthetic fibers 13 having a sectional shape that is divided into a plurality of sections by A printing paste containing a non-drawing dye showing dyeability is printed on the surface layer portion 1 of the plurality of composite synthetic fibers 13 without dyeing the lower layer 14 of the pile 16.
The sea component (11) of 5 was dissolved and removed, and the island component (1)
2) can be dyed and manufactured.

[0009]

[Example] As the two kinds of fiber materials 11 and 12 having different solubilities with respect to the etchant, nylon, general polyester,
All of the fiber materials forming conventionally known composite synthetic fibers such as modified polyester, acrylic ester, polystyrene, aromatic polyamide, polyvinyl formal, polyvinyl chloride, polyethylene, polypropylene and the like can be used.

As the etching agent, for nylon, toluenesulphonic acid, benzenesulphonic acid, xylenesulphonic acid, cresol, chlorophenyl, sulfuric acid, hydrochloric acid, nitric acid, etc. are generally used but do not contain a sulfonic acid metal base. Sodium hydroxide, cresol, for polyester

When the sea component 11 is dissolved and removed, the sea component 11 is dissolved and removed, and the remaining island component 12 can be dyed at the same time. In that case, the discharging agent shall be printed on the pile surface together with the non-staining dye, whereby the sea component (11) of the surface layer portion 15 of the plurality of composite synthetic fibers 13 is dyed without dyeing the lower layer 14 of the pile 16. ) Can be dissolved and removed, and at the same time, the island component (12) can be dyed. When the sea component 11 to be dissolved and removed is blended with a pigment, particularly carbon black fine powder, the sea component 11 is dissolved and removed to form a pile surface layer. It is deeply affected by the black shadow of the sea component 11 (13) colored with the pigment forming the lower layer 14 of the layer, thereby darkening the pile surface and sharply revealing the discharge pattern drawn there. You can do it.

More specifically, a modified polyester fiber material modified by introducing a sulfonic acid metal base is used as a sea component, and a general polyester fiber material having no sulfonic acid metal base is used as an island component. When a composite polyester filament 13 having a single yarn fineness of 15 denier having a cross-sectional shape in which the components are radially divided into 8 sections is used as pile yarn (total denier; 3500 denier), clay such as diatomaceous earth and montmorillonite, locust bean gum, Using a water-soluble paste such as guar gum as the base paste, and adding an alkali-immiscible dye together with an alkali-resistant deep-dyeing agent and an alkali-resistant penetrant to a printing agent, remove sodium carboxylic acid chloride and sodium trichloracetate. It is compounded as an etchant, printed on the pile surface, and evaporated and colored (initially 10
Steaming at around 0 ° C for 30 minutes, then at around 170 ° C for several minutes, dipping in a reducing bath of sodium carbonate, hydrosulfite, etc. for reduction treatment, and then washing and drying the surface of the pile layer. The modified polyester fiber material (sea component 11) of 15 is dissolved and removed, and a discharge printing pile fabric is obtained by using an ultrafine polyester fiber (12) less than 1 denier of the general polyester fiber material (island component 12). When overcoating the pile surface with a printing paste containing a removable dye and an etchant,
A plain pile fabric in which the pile layer is divided into upper and lower parts by the surface layer of the ultrafine fibers 17 and the composite polyester filament 13 is obtained.

[0013]

In the present invention, one of the two kinds of fiber materials 11 and 12 having different solubilities in the etchant is the sea component (11) and the other is the island component (12), and the island component (12) is the sea component (11). In the surface layer portion 15 that does not reach the lower layer portion 15 of the pile 16 that is composed of a plurality of composite synthetic fibers 13 having a cross-sectional shape that is partitioned into a plurality of sections by), each of the plurality of composites that configure the pile 16 When the sea component (11) of the synthetic fiber 13 is dissolved and removed, a plurality of fluffs due to the island component 12 of the plurality of compartments, which have been integrated by the sea component (11), appear at the tip of each composite synthetic fiber 13. Become.

In other words, each of the composite synthetic fibers 13 forming the lower layer portion 14 of the pile becomes a plurality of fluffs at the tip portion to form the surface layer 15 of the pile. In the surface layer portion 15, although the mass is reduced by the amount by which the sea component 11 is dissolved and removed, the number of fluffs forming the surface of the pile layer is increased several times, so that the hair is bulkyly opened. For this reason, when a discharge agent for dissolving and removing the sea component 11 is partially applied to the pile surface to draw a discharge pattern, a substantial difference in fiber density between the printed portion and the non-printed portion is observed. Does not occur, and a plain pile fabric having a pile surface is obtained.

When printing a printing paste containing a discharge agent for the sea component (11) and a non-staining dye for the island component (12), the discharge pattern becomes colorful, and the surface of the printing spot is the surface. When the pigment, preferably carbon black, is kneaded and mixed onto the soluble fiber 11 which remains undissolved under the colored insoluble fiber fluff 12 of the above, the soluble fiber 11 becomes dark. Printed area by shading (12)
The color of is deepened, and the pattern of corrosion is deep and deep.

Thus, even if the surface layer portion 15 of the pile is darkened by the color of the lower layer portion 14, the fibers of the surface layer portion 15 (insoluble fibers 12) are the fibers of the lower layer portion 14 (composite synthetic fiber 13). The number of fibers is much larger than that of), and it is much thinner, forming a bulky and dense surface layer. Therefore, the color of the fiber (composite synthetic fiber 13) of the lower layer portion 14 cannot be seen through, and therefore the printing is performed. It is not necessary to prepare the paste with a low viscosity and to print it.Therefore, the printing paste does not exude from the printing mold, and a different color printing paste is laminated on the entire pile surface to create a sharp print. It is possible to depict the erosion pattern.

The fluff 12 formed by dividing one composite synthetic fiber 13 into a plurality of non-soluble fibers is extremely fine and easily set, but in the present invention, the upper end forming the pile surface of the composite synthetic fiber 13 Only the portion 15 is extremely thin, and the lower layer portion 14 that supports the upper end portion 15 is a thick one composed of the sea component (11) and the island component (12), so it is not easily tired, and a normal pile fabric is the same. A pile fabric having cushioning properties can be obtained.

[0018]

As described above, according to the present invention, there is no step difference in the feeling caused by the difference in fiber density between the printed portion and the non-printed portion of the discharging agent on the pile surface, and the sharp cutting at the time of the die is performed. It is possible to obtain a pile fabric having a cushioning pattern suitable for carpets, in which an eclipse pattern is drawn and the pile surface is composed of ultrafine fibers, which has a soft touch and does not easily cause the pile to set easily.
