Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth suitable for car seats or carpets.

[0002]

2. Description of the Related Art Conventionally, a woven fabric made of polyester Taslan yarn (hereinafter referred to as Taslan woven fabric) has been widely used for automobile interior applications such as carpets, upholstered chairs and car seats. In recent years, especially as consumers have become more upmarket, it is expected that these textiles for automobile interiors will become more multicolored and require more complex and unique designs than monotone patterns with few colors. Is becoming.

Conventionally, as a method for making these Taslan fabrics multicolored, a pre-dyed yarn which has been dyed in a yarn state in advance is used, or a fiber having different dyeing characteristics, for example, an ordinary polyester or a cationic dye dyeable type is used. Disperse dyes, cationic dyes, using polyester and nylon,
And a method of separately dyeing each with an acid dye.

By the way, when the yarn-dyed yarn is subjected to a two-feed Taslan process, it cannot be obtained by anti-dyeing, regardless of whether it is used on the core side or the sheath side.
It is possible to obtain a product having a complex and rich color.

[0005]

However, on the other hand, the yarn-dyed yarn not only has a complicated manufacturing process and is costly,
Since uniform dyeing itself is difficult, color spots easily occur,
It was difficult to obtain high-quality products.

Further, when fibers other than polyester are used as the fibers having different dyeing characteristics, the light fastness and weather resistance are generally low, and there is a problem that the function as a carpet or automobile interior application cannot be satisfied. Not only that, but the number of colors is limited to at most 2 to 3 colors, and thus there remains a problem to be solved in that the obtained fabric lacks a high-grade feeling.

Therefore, the present invention provides a Taslan cloth suitable for carpet or automobile interior applications, which has a complex and multicolored high-class feeling due to anti-dyeing and is excellent in light fastness and weather resistance. The purpose is to

[0008]

According to the present invention, a disperse dye-dyed polyester is obtained by dispersing a pigment in a dyeable polyester, and a disperse dye-dyed non-dyed polyester yarn B is used. And non-primed polyester yarn C that is dyeable with a cationic dye, and these three types of yarns are Taslan-processed as core yarns and / or sheath yarns, respectively. The fabric composition ratio of the strip is 5 to 30% by weight for A and 50 to 90 for B with respect to the total weight of the fabric.
The Taslan fabric is characterized in that the weight% and C are 5 to 40% by weight (A + B + C = 100), and the entire fabric is additionally dyed.

The polyester dyeable in the disperse dye used in the present invention is a polyester substantially insoluble in the cationic dye, and 80 mol% or more of each of the dicarboxylic acid component and the glycol component is terephthalic acid. And polyalkylene terephthalate consisting of alkylene glycol, and particularly preferably consisting essentially of polyethylene terephthalate or polybutylene terephthalate.

Examples of the polyester dyeable with a cationic dye include those obtained by copolymerizing the above polyester with, for example, 0.1 to 10 mol% of a 5-sodium sulfoisophthalic acid component. Particularly preferred is a copolymer of 1.0 to 5.0 mol% of sodium dimethyl sulfoisophthalate or diethyl 5-sodium sulfoisophthalate.

The primary dyed polyester is obtained by adding and dispersing various pigments to the disperse dye and a dyeable polyester, and as the pigment, there are known azo lake type, benzimidazolone type, diazolide type and condensation type pigments. Azo type, quinacridone type, dioxazine type, isoindolinone type,
Various organic pigments such as vat type and phthalocyanine type, or titanium yellow, iron oxide, cobalt blue,
Various inorganic pigments such as chromium oxide, cadmium sulfide, carbon black and the like can be used, and any known dye or mixture thereof which can be generally used for coloring polyester can be used.

In the present invention, in order to provide a good texture for carpets or fabrics for automobile interiors, and to give a feeling of high quality, a two-feed type is used at the stage of the raw yarn.
Taslan processing is performed, but in this case, the use of the spun yarn can be applied to any part regardless of the core yarn and the sheath yarn. Of course, it can be used for both the core and the sheath.

However, in considering a fine multicolor expression,
Non-primed polyester yarn (B
And C), and on the other hand, a Taslan process is performed on the sheath or core by using the primary dyed polyester yarn, and after finally forming the fabric, it is further additionally dyed with a disperse dye and a cationic dye. As a result, the non-dyed yarns B and C, which occupy the majority of the fabric, are clearly dyed, and the color tone of the undyed yarn A is added to this, and at least two or more multicolored feelings are obtained in the two dyeing steps. This is because it is possible to obtain a taslan cloth that is rich in quality and has a high-class feel.

In the Taslan fabric of the present invention, it is necessary that the proportion of the dyed polyester thread A obtained by dispersing the pigment in the disperse dye-soluble polyester is 5 to 30% by weight. 5% by weight of the original polyester yarn A
If it is less than the above, the cost will be reduced, but the multicolor expression becomes difficult, and the significance of using the spun yarn is lost. On the other hand, if it exceeds 30% by weight, the proportion of the portion where the color changes due to the anti-dyeing becomes small, so that the vivid dyeing feeling is deteriorated and the color change width becomes narrow, which is not preferable, and the proportion of the spun yarn increases. Therefore, the cost is high.

The proportion of the non-primed polyester yarn B (not dyed with cationic dye), which is dyeable with disperse dyes, is 50 to 90.
Must be% by weight. If this ratio is less than 50% by weight, the strength of the entire fabric is lowered and the cost is increased, which is not preferable. On the other hand, when it exceeds 90% by weight, the amounts of the primary dyed yarn A and the non-primed polyester yarn C which is dyeable with a cationic dye are relatively decreased, and it becomes difficult to express in multiple colors.

Further, the proportion of the non-primed polyester yarn C dyeable with the cationic dye must be 5 to 40% by weight. If this proportion is less than 5% by weight, it becomes difficult to express a multicolor image and the proportion of sharply dyed portions is reduced, which is not preferable. On the other hand, if it exceeds 40% by weight, the light resistance and the weather resistance are deteriorated and the cost is increased, which is not preferable.

In the production of the fabric of the present invention, the above 3
Two-feed Taslan processing may be performed using various types of polyester yarn, and then woven or knitted, and further dyed. More specifically, when processing two feed taslan, for example, a delivery roller speed of 70 to 1
0-m / min, 70-110 m / min core yarn, 1 sheath yarn
It may be supplied at a rate of 15 to 220 m / min.

The two feeds obtained in this way
The Taslan textured yarn is woven or knitted to form a cloth. Table 1 shows a structural example of a fabric using such a two-feed Taslan textured yarn.

[0019]

[Table 1]

Next, the obtained cloth is subjected to scouring and relaxation treatment, and then subjected to additional dyeing with a cationic dye and a disperse dye.

[0021]

In the Taslan fabric of the present invention, the fabric containing the dyed yarn is additionally dyed with a cationic dye and a disperse dye, so that the fabric is rich in complex and multicolored feeling, which has never been obtained by anti-dying. Since it is made of polyester yarn, it is excellent in light fastness and weather resistance and is suitable as a material for carpet and automobile interior applications.

[Table 2]

The obtained raw fabric was dyed green with a cationic dye and then further dyed with a gray disperse dye for finishing. The obtained product was of high quality with a high-grade feeling, with the four colors of red, blue, yellow of the primary dyed polyester yarn and green of the cationic dye appearing as various fine color patterns in the gray background. Further, it was excellent in both light fastness and weather resistance, and could be sufficiently used as a material for carpets and automobile interiors.

Examples 2 to 4, Comparative Examples 1 to 4 Staining polyester yarn (A1 + A2 + A3), non-staining polyester yarn (B1) dyeable to disperse dye, and non-staining polyester yarn dyeable to cationic dye Table 3 shows the usage ratio of
A Taslan fabric original fabric was prepared in the same manner as in Example 1 except that the changes were made as described in 1. Then, the obtained raw fabric was dyed and finished in the same manner as in Example 1 to obtain a Taslan textile product. Table 3 also shows the evaluation results of the obtained products.

[0027]

[Table 3]

As shown in Table 3, among the obtained products,
Each of the Taslan fabrics of the present invention had a variety of color patterns to give a high-class feeling, and was high in quality and good in light fastness. On the other hand, in the Taslan fabrics other than the present invention, since the amount of the primary dyed yarn (A1 + A2 + A3) is small, it is difficult to express in multiple colors (Comparative Example 1). Since the amount of (B1) used is small, the fabric strength is insufficient (Comparative Example 2), and the amount of the non-dyed yarn (C1) dyeable with a cationic dye is too large and the light fastness is insufficient (Comparative Example 3). However, it had various drawbacks in that the amount of the dyed yarn (A1 + A2 + A3) was large and the range of color change by dyeing was narrow (Comparative Example 4).
