Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brushed fabric having good touch, high writing effect and anti-pill property.

[0002]

2. Description of the Related Art Conventionally, brushed fabrics similar to the present invention are disclosed in JP-B-54-28500 and JP-B-58-55260.
There is an official gazette. However, the fiber constituent polymer of these patents is polyethylene terephthalate, and although the texture, flexibility, and drape properties are relatively good,
The so-called lighting effect in which a pattern appears when a finger is traced on the touch and the surface is not sufficiently satisfactory. In order to express these properties, it is conceivable to use polyamides as a fiber-constituting polymer. In that case, however, fading due to washing or the like occurs due to poor dyeing fastness, and further, napped hair The disadvantage is that the judgement becomes worse.

[0003] Conventionally, there has been a method of improving the pilling resistance by lowering the fiber strength in terms of pilling, but this method is not practical because it is easily broken.

[0004]

DISCLOSURE OF THE INVENTION The present invention relates to a conventional method which has not only a good texture, flexibility and drapability but also a high touch, napping and lighting effect, and also has high dyeing fastness and anti-pill property. Not to provide a brushed fabric.

[0005]

The present invention employs the following means in order to solve the above problems. That is, the brushed fabric of the present invention mainly has an average fineness of 0.001.
In a raised fabric in which 3 to 8 spun yarns composed of ultrafine fibers of 1 to 1 denier or filament yarns are floated on a warp, and the wefts are mainly raised, the fiber constituent polymer of the wefts is It is characterized by being mainly composed of polypropylene terephthalate or a copolymer thereof.

[0006]

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a brushed fabric having not only a feeling, softness and drapability but also high touch, napping and lighting effects, and high dyeing fastness and anti-pill property. After careful examination,
By combining a specific structure and a yarn containing a specific polymer, it has been found that unexpectedly, such a problem can be solved at once.

[0007] The weft composed mainly of polypropylene terephthalate, which constitutes the brushed fabric of the present invention, has a fineness of 0.001 to 1 in order to develop dense nap.
It is necessary to use a spun yarn or a filament yarn made of the ultrafine fiber of d. That is, if it is less than 0.001d, it is too thin and the fiber separation property is inferior, and even if dyed, a dark color cannot be obtained,
On the other hand, if it exceeds 1d, the feel is rough and a smooth touch cannot be obtained. The fineness is preferably 0.005 d or more from the viewpoint of the color development of dark colors, and 0.9 d or less from the viewpoint of enhancing fine touch.

When the weft is a spun yarn, the count is preferably about 10 to 40 cotton count. In the case of a filament yarn, a multifilament of 50 to 500D is good,
It is also possible to use several ply yarns.

The means for producing the ultrafine fibers is not particularly limited, but it is preferable to produce sea-island type composite fibers of about 1 to 10 d and to subject them to ultrafine treatment mainly after weaving. In the case of sea-island composite fibers, the island component is polypropylene terephthalate or a copolymer thereof,
What mixed various additives for antistatic, antifouling, flame retardant, antibacterial, etc. may be used. In addition, as the copolymer component, various polyesters, polyamides, polyolefins, and the like,
There is no particular limitation as long as the desired properties are not impaired, and it may be selected in consideration of spinnability and the like. Further, the copolymerization ratio is not particularly limited, but preferably 40% or more of the polypropylene terephthalate portion is included in order to exhibit a good touch and lighting effect unique to polypropylene terephthalate.

On the other hand, as the sea component, polyolefins such as polyethylene and polystyrene, various polyamides such as nylon, and various polyesters such as polyethylene terephthalate can be used. It is preferable to use them in consideration of the processability such as solubility or division property.

In the case where a fiber made of polypropylene terephthalate or a copolymer thereof and a fiber different therefrom is used for the weft, components other than polypropylene terephthalate or the copolymer thereof include various polyamides and polyethylene. Various polyesters including terephthalate, polyolefins,
Various polymers such as polyurethane can be used. It is also possible to mix two types of polypropylene terephthalates having different copolymerization components.

[0012] The thickness of the fibers to be mixed does not need to be the same, and as a result, in the case of spun yarn, the count is cotton count 1
No. 0 to No. 40, 50 to 50 for filament yarn
There is no problem if it is a multifilament of 500D. The mixing ratio in this case is preferably at least 40% of the polypropylene terephthalate portion in order to exhibit a good touch and lighting effect unique to polypropylene terephthalate, as in the case of copolymerization.

In this case, the mixing method is as follows: polypropylene terephthalate is used as the island component 1;
Any method may be used, such as a method in which another polymer is melt-spun in the same sea-island type fiber, or a method in which the fibers are spun as separate fibers and then aligned and mixed when forming a multifilament.

The fiber used for the warp is not particularly limited, but it is preferable to use a stretchy bulky yarn in order to increase the weaving density, to have a voluminous feel, and to have a misalignment. As the stretched bulky processed yarn, false twisted yarn, scratched crimped yarn, indented processed yarn, asymmetrically heated processed yarn, shaped processed yarn, composite crimped yarn, and the like can be used. As the material of the processed yarn, thermoplastic polymers such as polyesters and polyamides are preferable. Particularly, when polypropylene terephthalate or a copolymer thereof is used, good touch, flexibility, drapability is enhanced, and a more luxurious feeling is obtained. Can be issued. As with the weft, various polymers such as polyesters, polyamides, and polyolefins can be used for the copolymer here.

The single denier of the warp is suitably 15 d or less. By using such a warp, the texture of the brushed fabric becomes less noticeable. Furthermore, in order to reduce the misalignment of the brushed fabric or to enhance the lighting effect, the single yarn denier is preferably 0.1 to 5 d. Further, as long as the above performance is not excessively impaired, other fibers may be mixed into the warp.

In the present invention, weaving is performed using the specific weft and warp as described above.
Eight floating structures are adopted. If the number is less than two, it is difficult to raise the hair. If the number is more than nine, a large loop-like ring is generated, which is not always preferable. A preferred example is 4
One to nine sheets of satin weave and its changed structure, such as those called Turkish weave and sable, can be used.

The brushed woven fabric of the present invention has a small woven structure density. Regardless of the type of yarn and the woven structure, the texture is conspicuous and a surface portion not covered with raised hair is easily formed, regardless of the type of yarn and the woven structure.
Therefore, it is preferable to use a high shrinkage fiber and to increase the shrinkage after weaving. The loom may be either a shuttle or non-shuttle type. In the case of weaving, in the case of using a stretched and bulky processed yarn as a warp, it is usual to apply a tension enough to extend the crimp, and when weaving, weaving occurs in the vertical direction. Other precautions for weaving are the same as those for general processed yarn fabrics.

In order to make the woven fabric composed of the above-mentioned yarn use and woven structure into the raised woven fabric of the present invention, it is usually subjected to heat treatment or shrinkage treatment, ultrafine treatment and napping treatment. These orders are arbitrary and two or more can be combined into a single step. When using ultrafine fibers obtained by the direct spinning method, of course, ultrafine treatment is not required,
Other substantially similar processing can provide an effective result. It is preferable to appropriately employ dyeing, intermediate setting, application of an oil agent, application of a polymer substance, shaving, buffing, modification of a defective portion, nap fixing, brushing, drying and the like as necessary.

When the ultrafine processing is performed by solvent extraction, it may be performed in combination with heat treatment or shrinkage processing. It is not always necessary to completely reduce the size, but it is sufficient that the size is reduced within a range in which the effect is realized. When the heat treatment or the shrinkage treatment is performed alone, the treatment is performed with hot water or steam at 80 to 180 ° C., or hot air treatment. During the heat treatment, if the shrinkage is reduced by 10 to 50% in the warp direction, the woven structure becomes dense and the raising property is improved. The means of brushing treatment is needle cloth, sandpaper, sandcloth, sandnet, whetstone, steel brush, polishing brush, sandroll, garnet,
Sand honing and the like. Above all, treatment with a needle cloth is effective. Depending on the application and woven structure, both sides may be raised.

The polymer substance may be provided as needed. The application of the polymer substance is aimed at improving the texture, the nap stability, the woven fabric balance, and the like. A typical example of the polymer substance is polyurethane, but it can be selected according to the purpose, such as nitrile-butadiene rubber, polyvinyl chloride, polyvinyl acetate, and polyamide. As a method of application, the solution or the dispersion is impregnated with the brushed fabric, or is applied from the non-brushed surface, and then solidifies in a dry or wet manner. When the amount of adhesion is large, brushing, buffing, combing,
It is also possible to improve the texture by brushing or the like.

EXAMPLES The present invention will be described in detail below with reference to Examples, but the scope of the present invention is limited by its effectiveness and scope.
There is no restriction.

The lighting effects in the examples and comparative examples were evaluated by the following test methods.

First of all, the counter is suspended vertically with respect to the ground so that the longitudinal direction is up and down and the width direction is left and right. Trace the surface upward about 10 cm. Next, trace at a 45 ° angle to the ground, and finally trace at a 30 ° angle. Grade 5 that can clearly confirm the lighting effect at any angle, Class 4 that can be confirmed fairly, good at some angles, but grade 3 that is less effective at certain angles, and can be confirmed only at specific angles Those that were rated as grade 2 and those that could hardly be identified were grade 1. Further, the anti-pill property was evaluated by a random tumble method (RTPT method) defined in JIS.

Example 1 A false twisted yarn of polyethylene terephthalate, 150 denier, 48 filaments was used as a warp, and a sea-island type fiber was used for the weft, and a fiber composed of polypropylene terephthalate for the island component and polystyrene for the sea component was used. This fiber had 16 islands, an island component ratio of 50%, 3.8 denier, a fiber length of 51 mm, a crimp number of 12 ridges / in, and this was used as a 20 / 2S spun yarn. This is woven density warp yarn 1
Five woven fabrics of satin weave were used so that the number of weaves was 00 yarns / in and the weft was 60 yarns / in.

This was introduced into boiling water, shrunk and dried, and then thoroughly washed five times with trichlene to dissolve and remove polystyrene as a sea component. Thereafter, the mixture was dyed dark blue using a disperse dye using a circular pressure dyeing machine, and an oil was added thereto, followed by drying.

This was passed through a French or German raising machine a total of 10 times to obtain a leather which had good nap texture and was almost inconspicuous.

Furthermore, DMF of MDI-based polyurethane using 75 parts of polyether and 25 parts of polyester
The solution was immersed and impregnated, and then wet coagulated and dried to obtain a surface paper-made woven fabric having a surface film. Next, brushing treatment was performed with sandpaper. As a result, a suede brushed fabric having a high lighting effect, a dense and good nap, a hardly noticeable woven structure, a soft texture, a good touch and a good drape property was obtained. The lighting effect of the obtained fabric was as high as 4 to 5 grades, and the anti-pill property was as high as 5 grades. In addition, as a result of a dyeing fastness test for washing described in JIS method, it was extremely good as grade 4-5.

Example 2 As a warp, a false twisted yarn of polyethylene terephthalate, 150 denier, 48 filaments was used, and a sea-island type fiber was used for the weft, a fiber made of polypropylene terephthalate for the island component, polystyrene was used for the sea component, and polyethylene terephthalate was used for the island component. A multifilament yarn obtained by mixing fibers composed of polystyrene with a sea component in a ratio of 6: 4 was used. In addition, the conditions such as the island component ratio and the fiber length of all the sea-island type fibers are in accordance with Example 1. Subsequent processing is Example 1.
The same conditions were used. Although the obtained product was slightly inferior in flexibility and drapability as compared with Example 1, a sueded brushed fabric having extremely high lighting effect and high density was obtained. With respect to the lighting effect, a nap made of two kinds of polymers, polyethylene terephthalate and polypropylene terephthalate, provided a more shaded product than that of Example 1 and was of the fifth grade. Similarly, the two types of polymers differed in color developing properties, so that they were marbling and had a more natural feeling than in Example 1. In addition, a result of 4-5 class was obtained for the anti-pill property. The result was a class 5 colorfastness to washing.

Example 3 A false twisted yarn of 150 denier 48 filaments of polypropylene terephthalate was used as the warp, and a sea-island fiber was used for the weft, and a fiber made of polypropylene terephthalate for the island component and polystyrene for the sea component was used. Thereafter, processing was performed under the same conditions as in Example 1. The obtained product was a suede-like brushed fabric having higher flexibility and drapability than in Example 1, and exhibiting a more luxurious feeling. The lighting effect of the obtained woven fabric was grade 5, and the anti-pill property was grade 5. The color fastness to washing was 4-5 grade.

Comparative Example 1 A sea-island type fiber was used for the weft and polyethylene terephthalate was used for the island component, and processed under the same conditions as in Example 1. The resulting brushed fabric had the same degree of denseness, texture, flexibility, and drapability as the fabric of Example 1 or slightly inferior. In addition, as a result of a dyeing fastness test for washing, it was extremely high, ie, a fifth grade. However, the lighting effect was grade 3 and the anti-pill property was grade 3-4, which were inferior to the examples.

[0031]

As apparent from the above description, the brushed woven fabric according to the present invention provides a feeling, flexibility and lighting effect by mainly using polypropylene terephthalate or a copolymer thereof as the weft or warp fiber constituting polymer. It has not yet existed, and has a wide range of effects, fastness to dyeing, high color development and anti-pill property, and can be widely used for clothing, material and the like.
