Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a printed carpet. More specifically, the present invention relates to a method for manufacturing a printed carpet made of pile warp knitted fabric.

Traditionally, in the field of carpet products, tufted carpets, in which pile yarn is tufted onto a primary base material such as polypropylene fabric using a tufting machine, have been mainstream, and in order to obtain these printed products, roller printing machines and auto screen printing machines have been used. Screen printing machines such as rotary screen printing machines and rotary screen printing machines were often used. However, the tufted carpet printed products manufactured using these printing machines are
Because the printing dyeing paste did not penetrate into the base of the pile yarn, the pile yarn was not colored uniformly, and only a marbled color pattern called "Memuki" could be produced.

Therefore, the quality of the printed carpet was extremely poor. One attempt to improve this "peeling" is to manufacture a carpet with a low pile yarn height, but the height of the pile yarn is reduced to the extent that "peeling" is not noticeable. There was a problem in that the repellency was significantly reduced, and only carpets with low commercial value could be manufactured.Meanwhile, as a solution to this problem, printing by lowering the viscosity of printing dyeing paste, and printing with solvent emulsion color Methods using glue have been considered. However, with either method, it is difficult to sufficiently penetrate the colored glue to the base of the pile threads that are tightened with the base fabric, and the sharpness (clarity of the color pattern boundary line) is difficult. In addition, the former method increases the amount of colored paste deposited, resulting in a marked drop in drying speed after printing, and although the latter method has a faster drying speed, problems such as solvent exhaust, dullness of color, and problems with the dye and paste used. There were drawbacks such as limited availability of agents.

Therefore, the only available takotido carpets other than conventional plain ones are products that use yarn-dyed pile yarns and create colored pattern effects by combining these different colored pile yarns, and these are products that are naturally different from printed and dyed patterns. There wasn't.

The inventors of the present invention have conducted intensive studies on a method for producing printed carpets that do not have the above-mentioned drawbacks, and have found that by using a specific pile warp knitted fabric that has not been previously supplied to the carpet field, and by printing this, the fabric is bulky and has rebound resilience. The inventors have discovered that it is possible to obtain a printed carpet with excellent quality, almost no "bleeding", and whose base fabric is also colored in the same color, and have thus arrived at the present invention.

That is, the present invention is a pile warp knitted fabric knitted by a warp knitting machine having a single row of needle beds, in which the ground yarns are not knitted by some of the knitting needles, so that the ground yarns extend in the wale direction in the ground knitted fabric. A thin fabric part is formed, and the pile yarn is three times or more thicker than the ground yarn and has a diameter of 800 denier or more, and is connected to the ground knitted fabric by knitting or insertion. This method of manufacturing a tossle-printed carpet is characterized by printing a carpet made of pile warp knitted fabric in which loop piles are formed in the thin portion.

The pile warp knitted fabric in the present invention is a pile warp knitted fabric knitted by a warp knitting machine having a single row needle bed, and the ground yarns are not knitted by some of the knitting needles, so that the ground yarn is not knitted by some of the knitting needles. A thin fabric part extending in the wale direction is formed, while the pile yarn is made of yarn that is three times or more thicker than the ground yarn and has a diameter of 800 denier or more, and can be knitted or inserted into a ground knitted fabric. It is characterized in that the thin fabric portions are connected to each other and form loop piles at intervals of one coat or more.

Furthermore, in order to achieve the effects of the present invention, this warp knitted fabric has a loop pile standing angle d and β of 60″ to 120°.
The height of the loop pile from the knitted fabric is preferably 156 or more, more preferably 1.51E.
m to 7.50.

The standing angle α of the loop pile is the angle between the perpendicular line drawn from the apex of the loop pile to the knitted fabric and the wale direction of the ground knitted fabric, as shown in Figure 3. The standing angle β is the angle between the perpendicular line and the knitted fabric. It refers to the angle with respect to the course direction of the earth.

Furthermore, it is preferable to set the density of the loop pile appropriately in order to uniformly start the loop pile. Normally, the optimum density of the loop pile changes depending on the thickness of the pile yarn, the gauge of the knitting machine, etc., so here the density of the loop pile is expressed by the pile yarn weight, but in the present invention, the preferable yarn weight is 200 to 6001. It's off. The pile yarn weight is the weight per unit area of the pile yarn constituting the pile warp knitted fabric.

The pile yarns that make up the pile loops are natural fiber yarns,
It may be recycled fiber yarn, synthetic fiber yarn, or a mixture of these yarns (the yarn form may also be spun yarn, long fiber yarn,
It may be bulky processed yarn, spun-like processed yarn, or tape yarn (
, it does not impose any restrictions. There are no restrictions on the ground yarns that make up the ground knitted fabric, but in order to color the carpet base fabric in the same way as the pile yarns, it is necessary to use fiber yarns that are dyed with the same dye type as the pile yarns. It is preferable to use them in combination. It is preferable to use undyed yarn/stripes or yarn-dyed threads as the ground yarn in order to prevent the undyed base fabric from showing through in carpets with a low pile yarn density, which is referred to as "ground see-through".・.

The textile printing machines used in the present invention are not particularly limited, and include screen textile printing machines such as auto screen textile printing machines and rotary screen textile printing machines, roller textile printing machines, and textile printing machines equipped with jet nozzles called jet printers. It can be used as is. Screen hand printing is also possible.

The printing is carried out, for example, as follows: A 5.degree. pile warp-knitted fabric is preset at 160 to 190.degree. C. for 30 to 60 seconds while being relaxed in an air float type tenter or the like. A heat treatment machine called a jet dryer that actively performs relaxation may be used. Subsequently, it is refined using an activator using a jet dyeing machine, a continuous winch, a continuous relaxer, etc.

After bleaching or fluorescent whitening in some cases,
Dehydrate. The dehydration may be carried out by continuous pressure air dehydration in the form of a spread cloth, or by center dehydration in the form of a rope and then spreading. The thus obtained vile warp knitted fabric is dried, subjected to an intermediate setting treatment so that there are no bends or wrinkles, and then rolled up. This rolled knitted fabric is introduced into a printing machine while being unwound, and is fixed on a printing stand coated with a tensioning agent so as not to cause any bending. When performing roller printing, control the tension of the knitted fabric on the supply side to prevent curling. When performing screen printing, the mesh of the screen should be 500° and 700°.
If you use a coarse paste, the color paste permeability will increase and it is effective for dyeing the base fabric, but if you use too coarse a color paste, it will be difficult to dry the color paste.Add a penetrant to the color paste. Although it is effective for dyeing the base fabric, it also causes a decrease in drying efficiency (adding various additives to the color paste, such as fixing agents as color fastness improvers, light fastness improvers) , ultraviolet absorbers, etc. may be added.Also, if sharpness is required for the color pattern, UV absorbers may be added.
A J-do inhibitor may also be used. Color development conditions after printing and drying may be determined by the type of fibers constituting the pile warp knitted fabric. The subsequent desizing treatment with water is carried out using a continuous winch or the like, and may also be treated with a bath containing an antifouling agent, a light fastness improver, a fixing agent, etc. The subsequent dehydration, drying, and finishing set are
Center dehydration, cloth spreading treatment, tenter drying, and finishing setting may be performed, or spreading and pressure air dehydration may be performed continuously, short loop drying, and tenter finishing setting.

The present invention will be explained below with reference to Examples, but is not limited thereto.

Example Using a warp knitting machine with a 1-row needle bed, a narrow bag with a specification of 14 yarns/inch was used, and with the structure shown in FIG. A nylon 140 denier/36 filament yarn was used for the pile yarn, and a nylon 1200 denier/60 filament bulky yarn was used for the pile yarn, and the warp knitted fabric A was knitted with the following runner length and batting density.

The color was developed by processing for a minute.

The colored knitted fabric (100 parts of colored paste composition) was put into a continuous winch, desized and washed with water at 60° for 30 minutes, then spread and dehydrated using pressure air, and then set at 170° for 30 seconds using a short loop/tenter. .

On the other hand, as a comparative example, a 2-ply yarn of 1200 denier nylon/60 filament bulky yarn was used as the pile yarn, and a polypropylene fabric with a basis weight of 90 F//ml was used as the base fabric under the following tact conditions. A tufted carpet gray machine C with a pile height of 4 m and a tufted carpet gray machine with a pile height of 2 holes were created. These tufted greige machines are tufted greige machine C%oG tufted machine stitch 8/inch tufted greige machine D %oG tufted machine stitch 10
/Imbu It was scoured and dried according to a conventional method, and printed in the same process as above to obtain a printed carpet.

The pile standing angle, pile height, pile yarn weight, and appearance observation results of the above four types of printed carpets are summarized in Table 1. As shown in Table 1, in the printed carpet made of pile warp knitted fabric using the method of the present invention, the dyeing of the pile yarn is good and there is almost no peeling (also, because the ground knitted fabric is dyed, the pile does not fall over). On the other hand, tufted carpet has noticeable peeling, and polypropylene fabric, which is a general-purpose base fabric, is difficult to dye and is not dyed. It can be seen that undyed base fabric is not a problem only in the case of a small carpet designed to prevent the pile from falling.
