DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a frosted fabric having a clear frosted pattern made of multifilant yarn.

2. Description of the Related Art Conventionally, there is known a woven fabric having a haze pattern using a synthetic fiber multifilament yarn (hereinafter referred to as thick and thin yarn) having a large fineness portion and a fineness portion along the longitudinal direction of the yarn. The thick and thin yarn is obtained by, for example, a method of incompletely drawing a polyester undrawn yarn having a birefringence Δn of about 0.5 × 10 ⁻³ to 10 × 10 ⁻³ as a supply yarn. However, the yarn obtained in this manner has a length of the fineness portion as short as 2 to 3 cm at most, and therefore the effect of the scratch pattern is poor. On the other hand, water or aqueous liquid is intermittently adhered to the highly oriented undrawn yarn of the thermoplastic synthetic fiber multifilament along the longitudinal direction, and the portion where the water or aqueous liquid is adhered by continuous hot drawing is used as the fineness portion. A thick fine yarn can be obtained by making a fineness fine portion in a portion where water or an aqueous liquid does not adhere and then false twisting with a low false twist number (Japanese Patent Application No. 61-89801 and Japanese Patent Application No. 62-189879). ). In the thick thin yarn obtained by this method, a portion where water or an aqueous liquid is intermittently adhered to the highly oriented undrawn yarn can be a thick dyeing thick portion, and its length is 5 cm or more and several tens cm. It is possible to obtain a fabric having a pattern with a frosted pattern, which can be lengthened to a certain extent and is far clearer than that of the thick and thin yarn.

The problem to be solved by the invention However, in order to obtain a clear frosted pattern effect in the thick yarn, the number of false twists adopted in the false twisting process following hot drawing is It was necessary to adopt a low false twist number, which is rarely adopted below, or to carry out false twist processing.
This is the high false twist number that is usually adopted (generally In the above), the false-twisting twist concentrates on the thick-dyeing thick portion having a high elongation, and the thick-dyeing thick portion is stretched by twisting deformation, and the difference between the thick-dyeing thick portion and the details is reduced. . Therefore, yarns that have undergone false twisting with a low false twist number and yarns that have not undergone false twist have low crimpability and non-crimpability, and the resulting woven fabric has a metallic luster And the slip was large even when woven with a normal weaving density, which was not always preferable for practical use for clothing. The main reason for this "tekari" and slip is that the filament yarn has low crimp or no crimp, and most of the light incident on the fabric returns as reflected light. The incident light causes diffuse reflection and is absorbed, and the reflected light is extremely small, so that the problem of "shine" does not occur. Further, since the crimps are low or non-crimped, the resistance between the yarns is small and slips are likely to occur. On the other hand, the ordinary stretched yarn has a moisture-free shrinkage ratio set to about 8% or more, and the ordinary crimped yarn causes shrinkage of the woven fabric at the time of dyeing. By releasing the strain received during weaving due to shrinkage and arranging the yarn in a stable position, unevenness can be formed on the surface of the fabric, thereby eliminating "glistening" and slippage. However, low-crimped or non-crimped thick thin yarns having thick-dyed thick parts can be obtained by drawing at high temperature and then false-twisting at low false-twisting number at high temperature, resulting in extremely low hot water shrinkage. (5% or less), the shrinkage at the time of dyeing the woven fabric due to the low crimp is extremely less than that of the woven fabric using the drawn yarn or the woven fabric of the ordinary processed yarn, which promotes “shining” and slip.

The present invention solves the above problems, and an object of the present invention is to provide a frosted woven fabric which is excellent in the pattern effect of the frosted pattern and does not have defects such as "gloss" and slip.

Means for Solving the Problems In order to solve the above problems, the woven cloth of the present invention comprises:
Thick textured yarn that is a low crimping or non-crimping multifilament yarn that alternately has details of 5 cm or more and thick dyeing thick portions of 5 cm or more, and loop fluff yarn that is a multifilament yarn having loop fluff. It is characterized by having 50 or more loop fluffs / cm ^{2 on} the surface.

In the kasuri woven fabric of the present invention, the warp yarn is a low-crimpable or non-crimpable multifilament yarn having 5 cm or more in the longitudinal direction and 5 cm or more of deep-dyeing thick part alternately. Or, it is used for at least a part of any one of wefts or each part of a warp and a weft, and is woven with a loop fluff which is a multifilament yarn having a loop fluff on the yarn surface, and 50 loop fluffs are formed on the woven surface. It is formed in cm ² or more.

The thick-textured yarn is water or aqueous liquid intermittently adhered to the highly oriented undrawn yarn of the thermoplastic synthetic fiber multifilament as described above intermittently along the longitudinal direction to continuously draw water, It is possible to obtain a thick dyed thick part where the aqueous liquid adheres and a finer part where water or the aqueous liquid does not adhere, but both the detail and the thick dyed thick part must have a length of 5 cm or more. For example, it is not possible to form a clear and faint pattern that the present invention is directed to, and to have a low crimping property or a non-crimping property in order to make the difference between the thick-dyeing thick part and the details clear. is necessary.

The loop fluff is formed by protruding filaments in a loop shape on the surface of the fabric, and 50 loop fluff / cm ²
If the amount is less than the above, the amount of light reflected from the woven fabric is blocked by the loop fluff so that the effect of preventing "shining" cannot be obtained, and the resistance to slip is small and the effect of preventing slip cannot be obtained. The measurement of the number of the loop fluff is
10 squares of 1 cm ² are arbitrarily drawn on the surface of the woven fabric, and the number of loop fluff in the square is visually counted by a stereoscopic microscope, and the average number per 1 cm ² is shown.

In order to form loop fluff on the fabric surface as described above,
A loop fluff yarn having loop fluff on the yarn surface is interwoven with the thick and thin textured yarn. This loop fluff yarn can be obtained by aligning multifilament yarns having different elongations and false twisting or air jetting the multifilament yarn, but the fluff index of loop fluff yarn and the ratio of interweaving This makes it possible to adjust the number of loop fluffs on the fabric surface. When using this loop fluff yarn for 1/2 of the woven fabric, the fluff index of the loop fluff yarn is at least 50 pieces / m or more, and when used for 1/4 of the woven fabric, the fluff index of the loop fluff yarn is 100 pieces
/ m or more is required. The fluff index of the loop fluff yarn refers to the count number when measured with a gauge of 0.5 mm using an F-index tester (manufactured by Shikishima Spinning Co., Ltd.).

It is desirable that the loop fluff yarn has a small difference in color from the details of the thick-worked yarn in order not to reduce the pattern effect of the thick-worked yarn to be interwoven. Is preferably a fiber having the same composition, and it is preferable to use a drawn yarn for the loop fluff yarn in order to match the hue with the details of the thick and thin textured yarn.

According to the above configuration in Splashed tone fabric effects present invention, since they have 50 / cm ² or more loops fluff on the surface, the handle to the light irradiated to the surface by deep dyeing property thick portion of FutoshiHoso yarn The reflected light that represents the effect is transmitted, and the strong reflected light due to details is blocked, and the reflected light is selected and transmitted to show a clear frosted pattern effect, and the "shine" due to the reflected light in detail is provided. It is also possible to prevent slippage even with a woven fabric that does not shrink much during dyeing and finishing.

Examples Example 1. Birefringence obtained by high-speed spinning, using a polyamide highly oriented unstretched yarn 13d / 40f having a birefringence of 36 × 10 ^-3 , an aqueous liquid was intermittently adhered thereto, hot stretched, and then 1700 T / The false twist process is performed with a low false twist number of M, and the fineness is 93d, the minimum length is 50 cm, and the maximum length is 220.
cm, denseness thick part 108d, minimum length 7cm, maximum length 18c
m thick and thin processed yarn 1 was obtained. On the other hand, polyamide stretched yarn 100d / 24
Using f, an air jet process was carried out to obtain a loop fluff yarn 2 having a fluff index of 180 / m. The thick processing thread 1 and the loop fluff thread 2
Using 2 and 2 for warp and 2: 2 for weft, weaving was carried out in a plain weave design to obtain a woven fabric having a warp density of 101 yarns / inch and a weft density of 92 yarns / inch shown in FIG. This woven fabric is made with the usual polyamide dyeing formula (dye: Nylon Sun Red FGBL 0.5% ow
stained with f). In the obtained woven fabric, the dark color of the thick thick portion 1a of the thick processed yarn 1 is clearly recognized in a faint tone, and many loop fluffs 2a due to the loop fluff yarn 2 are present. Table 1 shows the evaluation of the number of fluffs, the “shine” and the slip property of this woven fabric.

As a comparative example, the thick and thin textured yarn 1 was used for all warp yarns and weft yarns and woven with the same design as in Example 1 and dyed in the same manner. The evaluation results of the obtained woven fabric are also shown in Table 1.

The woven fabric of this example was an excellent woven fabric that had a clear, frosted pattern effect and was free from defects such as "shine" and slips peculiar to textured yarn. On the other hand, the woven fabric of the comparative example is
Although it showed a clear pattern effect, it had a strong "shine" and a large slip property, so it was not practical for clothing. Note that the roughly acceptable slip property is JIS L10.
It is 1.2 to 1.5 mm or less in the 62A method.

Example 2. Birefringence index obtained by high-speed spinning was 53 x 10 ^-3 polyester highly oriented undrawn yarn 110d / 36f, using water intermittently attached,
Heat-stretched, then false-twisted with a low false-twist number of 1880T / M. Fineness 78d, minimum length 78cm, maximum length 1138c
m, deep-dyeing thick part 105d, minimum length 10cm, maximum length 25c
A thick thread of m was obtained. On the other hand, polyester drawn yarn 100d / 72
Using f, air jet processing was performed to obtain a loop fluff yarn having a fluff index of 150 / m. A plain weave was made with a warp density of 98 yarns / inch and a weft yarn density of 90 yarns / inch using the thick and thin processed yarns as warps and the loop fluff yarns as wefts. This woven fabric is dyed with a normal polyester dyeing formula (dye: Dyniax Black
HG-FS 0.5% owf). The obtained woven fabric was a bulky woven fabric having a black frosted pattern, no "glare", and good evaluation of slip property of 0 mm and weft of 0.5 mm (JISL-1062A method).
