Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic filament mixed woven fabric, a method for producing the same and a dyeing method, more specifically, a synthetic filament mixed woven fabric having excellent physical properties and texture.
It relates to the manufacturing method and the dyeing method.

[0002]

2. Description of the Related Art A woven fabric using a synthetic fiber filament made of regenerated cellulose fiber has an advantage of being excellent in texture, moisture absorption, sweat absorption, antistatic, slippage, etc., but has a drawback that it is inferior in physical properties such as strength and washing shrinkage rate. Have. Therefore, in order to improve the shrinkage rate of washing in particular, a method of improving shrinkage resistance by applying shrinkage-proofing (resin processing) in the post-processing is adopted. However, such a method has a problem that the processing cost is increased and the strength of cellulose, particularly the abrasion strength is lowered. On the other hand, the woven fabric using synthetic filaments made of synthetic fibers is excellent in physical properties such as strength and washing shrinkage, but has a drawback that the texture, moisture absorption, antistatic property, etc. are inferior to the woven fabric using synthetic filaments.

In recent years, in order to combine the respective advantages of the synthetic filament and the synthetic filament, the development of a mixed woven yarn by air processing or the like has been studied. However, in the case of woven fabrics that use mixed woven yarn, the processing cost for mixed
There is a problem such as texture change. Further, in the interwoven fabric using synthetic filaments for the warp or weft and synthetic filaments for the weft or warp, satisfactory physical properties and texture have not been obtained. By combining synthetic fibers with synthetic fibers in this way, it is desired to develop a woven fabric capable of simultaneously maintaining the advantages of synthetic fiber fabrics and synthetic fiber fabrics and rationalizing the processing cost. The current situation is that they have not been obtained.

SUMMARY OF THE INVENTION An object of the present invention is to provide a synthetic filament filament woven fabric having excellent physical properties such as strength, shrinkage upon washing, abrasion resistance, moisture absorption, antistatic property and the like, a method for producing the same, and a method for producing the same. To provide a dyeing method.

[0005]

The inventions claimed in this application are as follows. (1) In a woven fabric in which a weft yarn is interwoven with a warp yarn made of a synthetic filament and a synthetic filament, the fineness of each filament constituting the warp is ½ ≦ D _K / D _G ≦ 3.
(D _K in the formula is the fineness (denier) of the synthetic filament,
D _G has the relationship of the fineness (denier) of the synthetic filament), and the synthetic filament mixed woven fabric is characterized in that one synthetic filament and one synthetic filament of the warp are alternately arranged. (2) A method for producing a synthetic fiber filament woven fabric, comprising weaving using a warp yarn in which one synthetic fiber filament and one synthetic fiber filament are alternately arranged on one beam. (3) A method for dyeing a synthetic filament mixed woven fabric, which comprises subjecting the synthetic filament mixed woven fabric according to (1) to jet dyeing.

Examples of the synthetic fiber filaments used in the present invention include regenerated cellulose fiber multifilaments such as cupra rayon, viscose rayon and polynosic rayon, and semisynthetic fiber multifilaments such as acetate. Examples of the synthetic filaments used in the present invention include synthetic fiber multifilaments such as polyester, polyamide and spandex. The fineness of the synthetic fiber and the synthetic filament in the present invention is 1/2 ≦ D _K / D _G ≦ 3, preferably 1.0 ≦ D _K / D _G ≦ 3 (where D _K is the fineness (denier of the synthetic fiber ), D _G represents the fineness (denier) of the synthetic filament).

When D _K / D _G is less than 1/2, the physical properties such as strength and washing shrinkage are excellent, but the hard texture of the synthetic fiber remains and a good texture cannot be obtained. When D _K / D _G exceeds 3, the difference in fineness between the warp yarns of the synthetic fiber filament and the synthetic fiber filament wound in one beam becomes large, so that the surface state of the wound beam has a non-negligible irregularity. As a result, the weft is caught on the loose warp, and fluff is generated on the warp, so that the weavability is deteriorated. The fineness of the synthetic filament and the synthetic filament is preferably in the range of 20 to 250 denier,
From the viewpoint of the texture of the woven fabric, the range of 30 to 150 denier is particularly preferable. If the fineness is outside the range of 20 to 250 denier, the woven fabric is too thin or too thick, so that the woven fabric is suitable only for special applications.

In the present invention, the synthetic fiber filaments and the synthetic fiber filaments are alternately arranged one by one in a beam and used as warps. Arrange two or more of each filament alternately, one and two alternately or one and three
When weaving books alternately, the different yarns tend to be striped on the fabric, making it a striped fabric that can only be used for limited purposes. If the synthetic filament and the synthetic filament are separately wound into two beams, a new loom equipped with a two-beam feeding mechanism is required. Also, the one-beam supply mechanism is modified to a two-beam supply mechanism. Even if it is present, weaving problems are likely to occur, and it is difficult to obtain a good woven fabric.

As a method for preparing the warp yarns necessary for producing the woven fabric of the present invention, for example, (1) sizing the synthetic fiber filament and the synthetic fiber filament separately and rewinding them into one beam in the beaming step At the same time, a method in which each filament is alternately twilled and arranged one by one on the beam, (2) A synthetic fiber filament and a synthetic fiber filament are alternately arranged on a creel, and simultaneously sized. For example, a method may be used in which the fibers are alternately crossed one by one and arranged one by one on the beam.

The synthetic filament mixed woven fabric of the present invention can be obtained by setting the warp yarn prepared as described above on, for example, a weft free exchange loom and interweaving with the weft yarn.
As the weft used at this time, it is most preferable to use one synthetic fiber filament and one synthetic fiber filament alternately arranged as in the case of the warp, but depending on the application, two or more filaments may be arranged alternately. One and two yarns may be alternately arranged or one and three yarns may be alternately arranged and woven. Further, a mixed woven yarn of synthetic filament and synthetic filament may be used, and spun yarn may be used in place of the filament. The fineness of the weft is also not particularly limited, but the blending ratio of the synthetic fiber in the entire weft is preferably in the range of 10 to 70% from the viewpoint of physical properties in the weft direction and texture. Since the texture and the physical properties of the woven fabric are more strongly influenced by the warp, it is not possible to sufficiently bring out the advantages of the synthetic fiber and the synthetic fiber even when the synthetic fiber and the synthetic fiber are alternately arranged only in the weft.

The woven structure of the woven fabric is not particularly limited and may be a flat structure, a twill structure, a satin structure or a modified structure thereof, but a plain structure and a twill structure are preferred. There is no particular limitation on the fabric density. Regarding the method for dyeing and processing the woven fabric obtained in the present invention, as long as it is applied to synthetic fibers or synthetic fibers, any of high-pressure and normal-pressure dyeing methods may be used, and either synthetic fibers or synthetic fibers may be dyed, or either one of them may be used. One-sided dyeing is also acceptable. In particular, the woven fabric according to the present invention is less likely to cause wrinkles and scratches in the dyeing process as compared with the conventional synthetic fiber woven fabric. Method (a dyeing method in which a dyeing bath is circulated as a liquid flow) can be adopted, which has the advantage that the cost of the dyeing process can be rationalized.
