Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for printing warp knitted blankets called Meyer blankets.

[0002]

2. Description of the Related Art This type of warp knitted blanket is a warp knitted pile fabric knitted by a double Raschel warp knitting machine, and has a pile length of 5 mm or more, a pile areal weight of 1000 g / m ² or less, and a pile bulk density of 0. 0.01-0.1 g / cm ³ ,
The pile layer has bulky hair. In such a pile cloth that is opened in a bulky manner, it is not possible to draw a sharp printing pattern on the pile surface on the pile surface by using an ordinary screen printing machine or the like. 1
6 is sprayed with the printing liquid 30 by the spray 20 to perform a printing called aurora, in which the color at the time of the mold changes smoothly. It has a pile layer bulk density of 0.01 to 0.1 g /
With a warp knitted pile fabric that is extremely bulky with a hair opening of m ² , even when sprayed on the pile surface, it is difficult for the printing solution to penetrate deeply into the pile layer because it is blocked by the fluff on the surface. If you dare to penetrate deeply into the fabric, it will be meaningless to apply it by spraying the printing liquid as if it was flowing down, and even if you apply it to the pile surface without penetrating the printing liquid deeply, It is difficult to obtain a warp knitted blanket that vividly develops color because most of it is an acrylic fiber that is difficult to dye, but the back side 1
In No. 6, the pile root is locked to the base knitted fabric and is in a state of being converged without opening the hair. Therefore, the printing liquid adhering to the back surface 16 penetrates to the pile surface 17 due to the capillary phenomenon, and the aurora-like color of the pattern is formed. This is because the printing pattern that changes gently will be drawn.

[0003]

In the spray method in which the printing liquid permeates from the pile root to the pile tip by the capillary phenomenon as described above, whether or not the pile fiber is hydrophilic, the density of the base knitted fabric, and the opening of the pile layer Since the degree of penetration of the printing liquid changes depending on the moisture absorption (moisture content) of the warp knitted pile fabric, the oil content remaining in the pile yarn such as the spinning compounded oil, and the like, uneven quality is likely to occur.

[0004]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a printed warp knitted blanket having an aurora-like printing pattern and a stable quality by a spray method.

A sixth feature of the present invention is that, in addition to the above first to fourth features, a slit is provided between the pile surface and the nozzle.

A seventh feature of the present invention is that, in addition to the above first to sixth features, acrylic fiber is used as a pile material of a warp knit pile cloth.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The ground dyeing solution may be applied to the warp knit pile cloth from the front and back by a spray nozzle, or may be applied by dipping the warp knit pile cloth in the ground dyeing solution. The ground dyeing liquid excessively attached to the warp knit pile fabric is removed by a squeezing roll or vacuum to make the amount of the ground dyeing liquid attached,
After applying the discharge liquid, color development treatment is performed by dry heat or wet heat according to a conventional method, and washing is performed to finish. When the discharge liquid 19 is applied, it is preferable to spray the discharge liquid 19 from the nozzle 20 with the horizontal tip of the warp at a right angle to the pile surface 17 while conveying the warp knitted pile fabric 18 vertically. This prevents water droplets of the discharge liquid accumulated at the tip of the nozzle from dripping and creating stains on the pile surface.

When the discharge liquid is sprayed from a plurality of nozzles which move in the width direction of the warp knit pile cloth, the plurality of nozzles are arranged on a rod arranged at a required interval in the conveying direction of the warp knit pile cloth. A different printing pattern can be drawn by moving each of the support rods individually by mounting, cam or other driving means. FIG. 2 shows four pile rods that are reciprocally driven to the left and right at different cycles and speeds on the pile surface 17 of the warp knitted pile fabric 18 to which the ground dyeing liquid containing the removable dye and the non-durable dye is applied. The case where spraying discharge liquids having different compositions from the nozzles 21, 22, 23, and 24 attached to 31, 32, 33, and 34 to the pile surface is illustrated.

The nozzle 21 attached to the first support rod 31 is supplied with a discharge liquid containing a discharge dye of a different color from the discharge dye of the ground dyeing liquid. In the nozzle 22 attached to the second support rod 32,
The printing liquid containing a non-bleaching dye of a different color from the non-bleaching dye mixed with the discharge liquid supplied to the second nozzle 21 is supplied. Nozzle 2 attached to the third support rod 33
No. 3 is the dyeing solution and the first and second nozzles 21.
A discharge liquid containing a discharge dye of a different color from the discharge dye mixed with the discharge liquid supplied to 22 is supplied. The nozzle 24 attached to the fourth support rod 34 is supplied with the discharge liquid containing only the discharge agent without mixing the non-bleaching dye.

Therefore, on the pile surface of the warp knitted blanket, the base 1 is provided with a portion colored with the removable dye and the non-removable dye of the ground dyeing solution.
0, the discharge dyeing parts 11 and 11 'colored with the discharge dye of the discharge dye and the discharge dye of the discharge liquid sprayed from the first nozzle 21, and the discharge dye of the discharge dye And the discharge parts 12 and 12 'which are colored with the discharge dye of the discharge liquid sprayed from the second nozzle 22, the discharge dye of the ground dye and the third
The discharge parts 13 and 13 'colored with the non-discharge dye of the discharge liquid sprayed from the fourth nozzle 23 and the removable dye of the ground dye are discharged into the discharge liquid sprayed from the fourth nozzle 23. Discharged area 1 that is colored and colored only with the permanent dye of the ground dyeing solution
4. Other, non-detachable dye of ground dyeing solution and first nozzle 2
Different colors between the non-discharge dye of the discharge liquid sprayed from No. 1 and the non-discharge dye of the discharge liquid sprayed from the second nozzle 22. Color-coding by the discharge portion 15 etc. colored with three kinds of non-discharge dyes. A variety of aurora-like textile printing patterns will be drawn.

The printing pattern shown in FIG.
6 is attached to the support rods 31, 32, 33, and 34, and slits 25 are provided together with each nozzle 20 (21, 22, 23, 24).
Although the slit 25 is fixed and not moved, or when the slit 25 and the nozzle 20 are moved separately, the slit 25 and the nozzle 20 are intermittently moved only at the overlapping position. Since the discharge liquid 19 is sprayed on, the printing pattern becomes more complicated and diverse. The nozzle 20 is fixed when a monotonous striped textile printing pattern is to be drawn.

The discharging agent may be stannous chloride, stannous oxalate, stannous acetate, stannous fluoride, thiourea dioxide, hydrosulfite (diformaldehyde sulfoxylate zinc), depending on the type of pile fiber. Reducing discharge agents such as sodium diformaldehyde sulfoxylate), Rongalit (sodium sulfoxylate / formaldehyde condensate), and dechlorin (formaldehyde / sulfoxylate zinc salt) are mainly used, but depending on the type of pile fiber, It is also possible to use oxidative discharge agents such as potassium cyanide, potassium ferricyanide, dichromate and chlorate, and alkali discharge agents.

In the present invention, the "detachable dye" means a dye whose coloring function is lost by a discharge agent, and an azo dye or an indigo dye is mainly used. The "non-bleachable dye" means a dye whose coloring function is not lost by the discharge agent. In a general warp knitting blanket using acrylic fibers for the pile, the removable dye and the non-removable dye are selected from cationic dyes. The ground dyeing liquid and discharge dyeing liquid are prepared by adding a small amount of locust gum, guar gum, or other base paste to give viscosity, and mixing with a defoaming agent (mainly silicone is used) to prevent dripping from the pile fabric. It

The warp knitted blanket dyed according to the present invention can be napped on the back side to form a double-sided pile blanket, or a plain single-sided pile blanket can be combined on the back side to form a double-sided pile blanket. The present invention can also be applied to the discharge printing of the pile surface of a double-sided pile warp knitted blanket.

In this embodiment, the fourth nozzle 2
From No. 4, the discharge portion 14 with the discharge liquid D is not colored with the removable dye compounded in the ground dye liquid, but is colored with the non-discharge dye compounded in the ground dye liquid, which is a curved pattern different from that of the base 10. Will be drawn. In this case, if the discharge liquid A from the first nozzle 21 is blended with a non-bleaching dye having the same color as the removable dye blended with the ground dyeing liquid, the discharge portion 11 with the discharge liquid A It is colored and discharged in the same color as the base 10 dyed with the ground dyeing liquid. As a result, in the portion 11 'where the curve (14) drawn by the discharge liquid D and drawn and the curve 11 drawn by the discharge liquid A intersect, the removable dye compounded in the ground dye liquid is decolorized. However, since it is colored with the non-discharge dye of the discharge liquid A of the same color, the discharge portion 11 of the discharge liquid A is colored and discharged in the same color as the base 10,
Discharged portion 14 with discharge liquid D from the fourth nozzle 24
Does not have a continuous curved pattern, but is discontinuous and scattered in different colors.

As can be understood from the above, according to the present invention, a line drawing pattern (11) of different colors is drawn on the pile surface colored with the removable dye by several kinds of discharge liquids of different colors and crossed with each other.・ 14) and the intersections (11 ′) of the line drawing patterns (11 ・ 14) of different colors
Is a pile surface base colored with a removable dye (10)
It is also possible to obtain a complicated and various printed warp knitted blanket which is colored and discharged in the same color as the above and is drawn so that the intersecting line drawing patterns (14) of different colors are scattered on the base (10).

[0027]

As described above, according to the present invention, the discharge liquid 19 is directly sprayed and applied to the pile surface 17, so that the printing pattern can be surely drawn and the printing warp knitted blanket with stable quality can be obtained.
Even if the pile surface 17 is fluffy and the discharge liquid 19 does not penetrate deeply into the pile layer, the pile root 27 is colored with the ground dye liquid so that it does not remain as a cloth.
Since the discharge liquid adheres to the fluff of the pile, the printed pattern becomes aurora.

Since the slit 25 is provided between the pile surface 17 and the nozzle 20, the boundary between the discharge spot 28 where the discharge liquid is attached and the ground stain portion 29 where the discharge liquid is not attached can be made clear, and the printing pattern is neat. become.

Further, according to the present invention, as shown in FIG. 2, a non-bleaching dye is blended with the ground dyeing liquid, or a non-bleaching dye is blended with the discharge dyeing liquid, or the ground dyeing liquid and the discharge dyeing are blended. Each of the liquids is mixed with a different color non-bleachable dye, and further, the discharge liquid containing only the discharge agent without the non-bleachable dye is directed to the pile surface of the warp knitted pile fabric that is being conveyed. By spraying and applying from a plurality of nozzles that move in the width direction of the knitted pile fabric, various printed warp knitted blankets that are color-coded into removable dyes and non-durable dyes can be obtained.

Even if the pile surface is colored with the non-bleaching dye as described above, the present invention is based on the fact that an aurora-like textile printing pattern in which the color is gently changed between the molds is drawn as a decolorization mark. Therefore, it is suitable for dyeing acrylic fiber warp knitted blankets that are difficult to dye due to uneven stains.
When spraying the discharge liquid from multiple nozzles that move,
Even if stains are formed, the stains are hidden in a complicated and various printing patterns, and therefore the present invention is advantageous for a warp knitted blanket made of acrylic fiber.
