Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative fabric made of metallic yarn based on polyester μ, and more specifically, it has excellent durability and brightness, clear dyeability, and good texture. K provides fabrics with unique designs.

BACKGROUND ART Conventionally, fabrics made by mixing metallic yarns formed by vapor-depositing metals on a film base have been known as fabrics with high design qualities. However, known design fabrics have drawbacks in durability, dyeability, texture, etc.

A fabric with a design that satisfies all of these points is not known. For example, in the case of a fabric made of a mixture of metallic yarn and polyester fiber, which is made by metal vapor deposition on a polyester film base, it is necessary to dye it at high pressure (120°C or higher), and the metallic yarn-based polyester is also dyed, resulting in a loss of brightness. In addition, it has other drawbacks, such as the metal layer being susceptible to peeling or falling off. For this reason, in order to express aesthetics, it is possible to use yarn dyed yarn or thick yarn mixed with yarn, but this is not only disadvantageous in terms of high cost, lots, and delivery time, but also has color restrictions, and is not applicable to printed products. It has drawbacks such as the inability to Furthermore, when alkali weight loss processing is applied to improve texture, the metal layer, especially when the metal is AJ, has the disadvantage that the AJ is dissolved and removed, resulting in a loss of design, and the alkali weight loss process cannot be performed. ing. In order to solve these drawbacks, we succeeded in developing a fabric made of a mixture of metallic yarn and cationically dyeable polyester fiber, and filed a patent application.

Since the resulting decorative fabric can be dyed with cationic dyes, it is possible to obtain brightly dyed products without impairing glitter, and furthermore, by alkali weight loss processing, it is possible to obtain a decorative fabric with a good texture. You cannot get multicolor effects. In order to obtain a multicolored effect, it is necessary to mix yarn dyed yarn.

Issues arise in terms of cost, loft, and delivery time. The inventor of the present invention has arrived at the present invention as a result of intensive research aimed at developing a decorative fabric that does not have the above-mentioned drawbacks. That is, the present invention provides an atmospheric pressure dyeable polyester fiber dyed with a cationic dye and/or a disperse dye at atmospheric pressure, a metallic yarn 1 having a metal layer on a polyester paste that is undyable at atmospheric pressure and undyable with a cationic dye. This is a design fabric characterized by being composed of thione dye-dyable polyester fibers and other fibers if desired.

The pressure-dyeable polyester fiber used in the present invention is polyethylene terephthalate.

A polyalkylene terephthalate such as polybutylene terephthalate is usually spun at a high speed of 600 lj/min or higher, or the polyalkylene terephthalate is spun with additional components other than the apkylene terephthalate unit, such as isophthalic acid, Acid components such as adipic acid, geltaric acid, sepacic acid, and dimer acid, diethylene glycol, neopentyl glycol, neopentyl glycol/alkylene oxide adducts, bispheno-p/alkylene oxide adducts (adduct number: 10 moles or less), etc. Examples include atmospheric pressure dispersion dyeable fibers obtained by spinning a copolymerized polyester obtained by copolymerizing 20 molar glycol components at a high speed of 3000 m/min or more.However,
Particularly preferred is a sulfonic acid metal base-containing ester-forming component, such as 5
-Sodium sulfoisophthalic acid is 0.0% based on the total acid components.
It is an atmospheric pressure thione dyeable polyester fiber obtained by spinning a polyester obtained by copolymerizing 5 to 7 moy'%, preferably 1 to 6 mole L/%, at a normal spinning speed or at a high speed. Such li&fibers can also be pressure-dyed with disperse dyes.

Also, can it be obtained by copolymerizing a high-pressure thione dye-dyeable polyester fiber with an ester-forming component?

Alternatively, a cationic dye that cannot be dyed under atmospheric pressure can be obtained by blending polyalkylene terephthalate with a polyester containing a sulfonic acid metal group so that the content of the sulfonate metal group is about the same, and spinning the polyester obtained at a normal spinning speed. It is a dyeable polyester fiber.

In addition, the metallic yarn used in the present invention includes a metal layer formed by plating, metal vapor deposition, etc. on a polyester base that is not dyeable under atmospheric pressure or cationic dye, such as AJt Au + AfsCutNs*C.
r* Metallic yarn having Cr-Ni alloy + Ti layer etc. is exemplified. In the present invention, the above-mentioned atmospheric pressure dyeable polyester fiber
Fabrics are prepared by mixing high pressure "f1" dyeable polyester "I""' fibers with metallic yarns and, if desired, other fibers such as rayon-acetate, silk, wool, regular polyester ( Yarn-dyed or undyed fibers such as fibers (dyeable with crystal tension dyes) can also be used in combination. There are no particular restrictions on the form of blending, and examples include blended spinning, intertwisting, blended fibers, fabrics using composite fiber yarns such as cuckoo, or mixed knitting and woven fabrics. The cross-sectional shape of the fiber used is circular;
It may be irregularly shaped, hollow, etc., and fillers such as kaolin, silica, alumina, and polyalkylene glycol/L'
The fineness may be the same or different. Thick and thin thread may also be used. Furthermore, a grain effect can be obtained by changing the shrinkage behavior of the fibers used.

That is, in order to obtain a grain effect, for example, (1) use the shrinkage difference of the raw yarn (hot water shrinkage difference of 7 inches or more), (2) use the same type of yarn and heat set one side to give shrinkage and shrinkage.

■ Utilizing the untwisting force in the graining process due to the difference in twist (a combination of untwisted and twisted at 2,700 to 3,000 t/m); ■ Utilizing the difference in binding force between warp and weft in the structure.

Methods such as (2) utilizing the difference in warp tension (double beam), and (2) utilizing the difference in grain development power due to combinations of (2) to (2) may be adopted. The fabric can also be subjected to weight loss processing, but in such a case, due to the weight loss rate, high pressure thion dye dyeable fibers of about 1/10 (weight) of normal pressure thion dye dyeable fibers and normal pressure dispersion are used. It is preferable to mix dye-dyeable fibers (non-dyeable with cationic dyes). When regular polyester fiber is mixed, the weight reduction effect is poor, so it should be used as a pattern yarn, and the amount used is preferably 5% by weight or less. In this case, it is especially preferable to use it as a white thread (undyed) as a cationic dyeable polyester/I/fiber.

4 mol% 1 neopentyl glycol 9 alkylene oxide adduct (number of moles added 1.0 mol or less) 0.5 to 10 mol It is especially recommended to use fibers mainly composed of polyester fibers copolymerized from the viewpoint of light resistance. preferable.

In the present invention, the above-mentioned fabric is usually piece-dyed to obtain a designed fabric. That is, by appropriately combining normal pressure thion dyeing, normal pressure dispersion dyeing, and pressure thion dyeing, it is possible to obtain a vividly different-colored fabric without deterioration in brightness due to staining of the metallic yarn with the dye. In addition, the metal layer of metallic yarn can be subjected to alkali weight reduction processing without damaging the metal layer, and fabrics with excellent texture can be obtained. Texture,
It has many characteristics, such as not impairing physical properties, being able to express effects ranging from shading to different colors by using a single dye, and being able to easily obtain a grain effect in combination with a dyeing process. Furthermore, the fabric can be made into a fabric with even higher designability by applying an acid and/or alkali extraction process. Further, the dyeing may be partial coloring such as printing, and a complex pattern effect can be imparted by appropriately combining dyeing and printing.

The present invention will be explained below with reference to Examples.
