[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processed opal product using a fused yarn and a method for producing the same.

[0002]

2. Description of the Related Art Hitherto, a woven fabric in which a part of warp and / or weft yarns are periodically and coarsely arranged and woven has been known as a so-called hollow fabric, which is light and has a design effect. . However, such products have problems such as misalignment and lack of dimensional stability unless we carefully consider the types of yarns used and the design of the woven fabric during weaving. .

As an opal processing method, it is widely known that weaving is performed by combining fibers having different solubility, and only easily soluble fibers are dissolved and removed to obtain a woven fabric having a watermark pattern. However, in this method, it is necessary to prevent fraying after opal processing, and after the opal processing, it is necessary to design the woven fabric to a density that does not cause slip, and its application range is limited, It was difficult to obtain a so-called hollow fabric by opal processing.

[0004]

SUMMARY OF THE INVENTION The present invention is an improvement over the conventional method, which can be performed without causing misalignment even at a low density.
It is an object of the present invention to provide an opal processed product capable of stably obtaining a high quality knitted fabric or the like and a method for producing the same.

[0005]

The present invention has solved the above-mentioned problems by using a combination of a special heat-fused yarn and a readily alkali-soluble yarn with a plain yarn.

[0006] That is, the opal processed product of the present invention comprises: B. a yarn excellent in heat resistance and alkali resistance. A core-sheath composite yarn using a low-melting-point component in the sheath portion, which is excellent in alkali resistance; In a woven fabric containing heat-resistant alkali-soluble yarns, the B and C yarns are arranged in stripes with the A yarns on at least one of the warp and weft yarns, respectively. The woven fabric is fused by the melting of the sheath portion, and the C yarn is partially dissolved and removed.

In this product, the B and C yarns each have at least one of a warp yarn and a weft yarn,
The stripes and the woven fabric are arranged in a striped manner, and the woven fabric is subjected to a heat treatment to melt only the sheath portion of the yarn of the above B, and the woven fabric structure is fused at the melted portion. depositing a material to be alkaline with an alkaline substance or heated to at least a portion, is obtained by dissolving removal of the yarn of the C of said adhesion part, any thread of the A~C is
Also, it is preferable to use a polyester-based material as a main component .

[0008] The yarn A should not be deformed at the melting point of the sheath of the composite yarn B, and should be substantially stable under the alkaline treatment conditions for eating out the yarn C. , but are not limited to, usually of polyester-based textiles, if example example,
It is preferable to use a polyester fiber containing terephthalic acid as a main acid component and alkylene glycol having 2 to 6 carbon atoms (ethylene glycol is particularly preferable) as a main glycol component.

Next, as the core-sheath composite yarn of B, a normal or high-viscosity polyester fiber component having an intrinsic viscosity (η) of about 0.6 to 1.2 is used for the core, and a low melting point polyester is used for the sheath. br /> but those produced using Te le are all can be used,
It is preferable to use one manufactured so that the difference between the melting points of the core component and the sheath component is 30 ° C. or more. As the low-melting polyester to be used as the sheath component, adipic acid, aliphatic dicarboxylic acids such as sebacic acid, phthalic acid, isophthalic acid, such as aromatic dicarboxylic acids and / or hexahydroterephthalic acid, such as naphthalene dicarboxylic acid Contains a predetermined number of alicyclic dicarboxylic acids and aliphatic or alicyclic diols such as diethylene glycol, polyethylene glycol, propylene glycol, and para-xylylene glycol, and optionally adds oxyacids such as parahydroxybenzoic acid. For example, polyesters obtained by adding and copolymerizing isophthalic acid and 1,6-hexanediol to terephthalic acid and ethylene glycol are exemplified.

[0010] Further, as the alkali easily meltable yarn of C, any of those having a higher alkali weight loss rate than the yarns of A and B can be used.

Fibers or polyalkylene glycols of copolymerized copolyesters, sodium alkyl sulfonates,
Fibers made of polyester blended with 1 to 15% by weight of sodium alkylbenzene sulfonate and the like can be given. In particular, in the present invention, it is preferable to use polyethylene terephthalate containing 1 to 5 mol% of 5-sodium sulfoisophthalic acid or 5-potassium sulfoisophthalic acid and 0 to 10 wt% of polyethylene glycol (molecular weight 4000). .

In the present invention, the above-mentioned three kinds of yarns A to C are arranged in stripes on the warp and / or weft and woven into an opal fabric. In the warp and / or weft, it is essential that they are arranged in stripes with A. For example, when two kinds of yarns of A and B or A and C are arranged in stripes on warp or weft, The other yarn is one in which at least A and C or A and B are arranged in a striped manner. When three types of A to C yarns are used for either the warp or the weft, the other yarn is Even if it consists only of A, it also consists of two kinds of A and B or C,
Or three types. In addition, as a thread of A to C,
Two or more yarns may be used in combination as long as each of the above conditions is satisfied.

As described above, according to the present invention, the yarn B composed of the core-sheath composite yarn using the low melting point component only in the sheath portion is alternately striped or crossed with A and C as warp and / or weft. In order to weave the arranged woven fabric, by heat treatment in advance, only the sheath portion is melted, and after the woven fabric is fused at the melted portion, to perform opal processing, without causing fraying or misalignment, It is possible to easily and stably obtain a good quality product, and it is possible to manufacture an extremely dense hollow fabric by opal processing. Furthermore, since only the sheath portion of the yarn of B is melted and the core portion is kept in a monofilament state, the appearance and feeling of the woven fabric are both kept very good even when the yarn of B is fused. It is.

The conditions of the heat treatment applied prior to the opal processing are such that the sheath portion of the yarn of B is melted, but the core portion of B and the yarns of A and C are not substantially affected. Should be fine. In general, it is preferable to apply an opal process after applying a heat treatment in a state where tension is applied to both directions of the weft and the fabric to melt and cool the sheath portion of the core-sheath composite yarn of B.

The material used for the opal processing, that is, for dissolving and removing the yarn of C, is an alkaline substance used for ordinary opal processing, such as an aqueous solution of an alkali metal hydroxide, carbonate, bicarbonate or the like. Any of the included pastes can be used. However, when polyester fibers are used for the A and B yarns, they are not affected at these temperatures. It is preferable to use a substance which is acidic or acidic and becomes alkaline upon heating, for example, a food paste containing a salt of a carboxylic acid chloride and an inorganic paste. As the salt of chlorocarboxylic acid, a sodium salt of chlorocarboxylic acid is preferable, and a sodium salt of trichloracetic acid is particularly preferable. As the inorganic paste, for example, diatomaceous earth and / or montmorillonite is 50%
A paste containing the above is mentioned. It should be noted that a polymer paste such as etherified starch, locust bean gum, guar gum, carboxymethylcellulose, hydroxyethylcellulose, crystal gum, sodium alginate, and the like may be mixed with this.

[0015] The opal processing is carried out so as to form a watermark pattern on the woven fabric by printing with a paste of paste, or by applying an alkaline substance or heating to the entire woven fabric by a padding method or a dipping method. It may be carried out so that a substance which becomes alkaline is attached to obtain a so-called hollow fabric.

As described above, when a discharge paste containing a salt of a carboxylic acid chloride and an inorganic paste is used, the discharge paste is printed on a woven fabric, dried, and then subjected to a heat treatment at a relative humidity of 90% or more. Steaming). The heat treatment is preferably performed at 20 minutes or more for saturated steam at normal pressure, 15 minutes or more for saturated steam at high pressure, and 7 minutes or more at 160 ° C. for unsaturated high-temperature steam. A food paste consisting of a chlorinated carboxylic acid salt and a paste containing 50% or more of an inorganic paste has a pH of 4 at room temperature.
When dried at 60-120 ° C., pH 7-9
Further, when steaming is performed with saturated steam or high-temperature steam, the pH becomes 10 or more, and the eating effect is exhibited.
