Description

[Detailed description of the invention] The present invention is a nylon space dye carpent, more specifically a space dye carpet that can leave substantially uncolored areas in the pile pattern (leaving a white background) and can obtain a multicolored pattern. Regarding.

Conventional nylon space dye carpen using acidic dye density nylon threads is generally made by impregnating knitted fabric with a dyeing liquid of the ground color, squeezing out the dyeing liquid as appropriate, and then printing with a dark printing liquid. The knitted fabric is applied in a pattern using a device such as a roll, and the knitted fabric is steamed, washed, dried, and then used as a space-dyed pile yarn to produce a carpet.

FIG. 1 shows a conventional space-dyed yarn with a blank background.

Conventionally, space-dyed yarn with a white background is obtained by directly printing on a white material knitted fabric made of acid dye-dyeable nylon yarn, followed by steaming, washing, drying, and knitting.

As a result, as shown in FIG.
is formed, but essentially only the color difference due to the printing solution can be obtained.

As a result, even if a carpet was made by tufting the conventional space-dyed yarn, the pattern was monotonous.

The present invention relates to a multicolored space dicarpent that solves the above-mentioned problems. A colored part 5 using a coloring liquid with a low acid dye concentration and a colored part 6 using a coloring liquid with a high acid dye concentration are formed on the yarn, and the acid dye is adsorbed on the cationic dye dyeable yarn adjacent to the colored part. A space-dyed carpet in which a light-colored pattern 7 corresponding to a colored part 5 with a colored liquid with a low acid dye concentration obtained by this process and a light-colored pattern 8 corresponding to a colored part 6 with a colored liquid with a high acid dye concentration were developed. This is the summary.

In the present invention, the term "coloring" refers to ordinary dyeing and printing using acid dyes.

The space dyer vent of the present invention has an acid dye dyeable yarn and a cation dye dyeable yarn as its constituent units, in which nylon filament yarns serving as pile yarns are adjacent to each other.

The acid dye dyeable yarn (hereinafter referred to as R yarn) of the present invention is a deep dyeable nylon with increased dyeing capacity by adding, for example, alkyl diamine, and can be used together with normal R yarn.

In addition, cationic dye dyeable yarn (hereinafter referred to as C yarn) is a yarn that is dyed with a cationic dye (usually in the form of an amino group salt) by blocking the ends of nylon with sulfonic acid, carboxylic acid, etc. .

Each structural unit of the carpend pile yarn in the present invention is a nylon filament.

The C yarn and the R yarn may be intertwisted, or may be simply drawn together without intertwisting.

FIG. 2 shows the space-dyed yarn according to the present invention in a non-cross-twisted state.

A knitted fabric is formed from nylon filament yarns consisting of untwisted R yarns 3 and C yarns 4 as constituent units, and is first dyed with a coloring solution (generally light color) with a low acid dye concentration, and then colored with a high acid dye concentration. The knitted fabric is colored separately by a method such as printing with a liquid (generally dark color) using a coloring liquid with a high concentration of acid dye and a coloring liquid with a low concentration of the same acid dye.

After coloring the silk cloth with acid dye, it is steamed, washed, and
dry.

When the obtained colored knitted fabric is disassembled, as shown in FIG. A colored area (hereinafter referred to as a high-concentration colored area) 6 is obtained using a colored liquid with a high dye concentration, but the C yarn adjacent to the R yarn is
A small amount of acidic dye remains adsorbed at the position on the yarn guide by Fante Awaalska, and compared with the colored portion of the R yarn 3, a substantially white background effect is obtained.

The amount of acid dye adsorbed varies depending on the low concentration colored portion 5 and the high concentration colored portion 6 of the adjacent R yarn 3, and the acid dye is selected from leveling type, milling type, gold-containing yarn, etc.
It can be freely adjusted by changing H.

For example, by setting the pH to about 3 and using a leveling acid dye, the amount of dye adsorbed by the C yarn 4 can be considerably reduced.

In this way, by considerably reducing the amount of acid dye adsorbed by the C yarn 4, the space dye pattern of the R yarn 3 and the white area left on the C yarn 4 are contrasted, and the white area leaving effect can be made even clearer. It is possible.

On the contrary, for example, a metal-containing dye is used to increase the amount of acid dye adsorbed on the C yarn 4, thereby increasing the degree of coloring of the patterns I and 8 on the C yarn.

In this way, light-colored patterns 7 and light-colored patterns 8 with density differences are also developed at positions on the C yarn adjacent to the low-density colored portions 5 and high-density colored portions 6 of the space-dyed pattern of the R yarn 3.

In the present invention, the light-colored pattern on the C yarn corresponds to the colored portion on the R yarn means that each acid dye is adsorbed to a portion of the C yarn adjacent to the area where the same acid dye coloring solution is applied to the R yarn. This means that a light colored pattern is obtained.

When pile yarns consisting of adjacent C yarns and R yarns are dyed or printed with a coloring solution containing the same acid dye, the R yarns are colored with the acid dye, and the C yarns adjacent to the R yarns are colored with the same acid dye. In this case, a light-colored pattern is developed in which the acidic dye is adsorbed in the area corresponding to the R-uncolored area.

A carbent is made by tufting the C yarn and R yarn in a non-twisted state with the C yarns and R yarns aligned as shown in Figure 3, or with the C yarn and R yarn twisted together as shown in Figure 4. .

As a result, the car vent of the present invention also has the effect of leaving a clear white background, with the colored parts 5 and 6 on the R yarn and the light color pattern 7.8 on the C yarn.
provides a harmonious color tone and the desired colorful pile pattern.

Unlike the conventional space dye car bent in which only the R yarn is colored with acid dye, the present invention is different from the conventional space dyer bent in which only the R yarn is colored with an acid dye.As shown in FIGS. Because it is dyed, a space-dyed pattern is obtained in the R yarn, and the adjacent C yarn has a substantial white background effect compared to the R yarn, and a small amount of dye is adsorbed according to the dye concentration applied to the R yarn. Light-colored patterns can also be obtained using acid dyes.

By the method described above, the Space Dyker Bent of the present invention has a much more variety of pile patterns than ever before.
