Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polyester fiber / cotton blended-spun brushed woven fabric comprising a blended yarn of polyester fiber and cotton as a constituent, and more specifically, a blended yarn of polyester fiber and cotton as a constituent. Polyester fiber
The present invention relates to a polyester fiber / cotton mixed spun woven fabric formed by dyeing a cotton mixed spun woven fabric with a hydrophilic dye and then subjecting it to a raising process, and a bedding and an interior fiber product using the same.

[0002]

2. Description of the Related Art A blended yarn of polyester fiber and cotton (primary product) is formed as a secondary product woven by a loom, and thereafter, desired clothing, special clothing, secondary clothing materials, interior textile products, etc. Processed into a tertiary product.

By the way, a woven fabric obtained by weaving a blended yarn of polyester fiber and cotton has a plain appearance and a poor appearance. Therefore, in order to improve the ordinary commercial value, gas firing,
Various processes such as mercerizing process, shrinking process, raising process, shearing process, and polishing process are performed.

[0004] Of these processes, the processes other than the raising process are mainly carried out in order to make the woven fabric glossy, glossy or smooth.

On the other hand, in the raising process, the surface of the fabric is fluffed by a raising machine equipped with thistle seeds or needle cloth to give the fabric surface a soft and fluffy feel, flexibility or heat retention. This is what you do to do it.

[0006] Conventional napped fabrics are thick cotton yarn counts (20-22)
It is common to use a woven fabric using yarns (10th yarn, single yarn, etc.) after being napped.
Furano has long been popular as a textile product used in the winter.

However, raised fabrics using these cotton fabrics have the drawbacks of being thick, heavy, and time-consuming to dry after washing, and in the case of raised fabrics of cotton fabric, wrinkles frequently occur after washing. , Ironing is required, and there is a gap with current lifestyle habits.

Although some of the above-mentioned woven fabrics are used as plain white, most of them are dyed to enhance their decorative value.

In other words, the trend of textile products in recent years has shifted from the conventional print-like (patterned) to a plain color, and the sales of the product have been completely solid color. This tendency is that the cost of a plain material is lower than that of a printed product, and further, a large amount of a small amount of production is required, and thus a print requiring an expensive die cost has been shunned.

However, now that the plain color has become the mainstream of the market, the taste of the market is diversified, and the monotonous plain dyeing to the complex plain dyeing are required.

However, there are the following problems in dyeing a woven fabric made of a mixed yarn of polyester fiber and cotton.

That is, cotton has a coarse fiber structure, so that the dye is easily diffused in the fiber, has excellent dyeability, and can be easily dyed with a direct dye, an acid dye or other hydrophilic dye. It has (easy dyeability).

On the other hand, the polyester fiber has a dense fiber structure, and the dye does not easily sit on the hydrophilic dye and exhibits a difficulty in dyeing. As a result, the dye cannot be dyed unless it is a special dye composed of a mixture of a pigment and a synthetic resin. It has the property that it does not exist.

That is, when a hydrophilic dye is used for dyeing or printing a polyester / cotton blended fabric, the cotton side (cotton fiber of the blended yarn) is effectively dyed, but the polyester side (blended yarn) Polyester fiber)
Is not sufficiently dyed, and therefore, uneven coloring may occur in the dyeing of polyester / cotton blended spun fabrics. Therefore, when dyeing or printing polyester / cotton blended spun fabrics, use a mixture of pigment and synthetic resin. Was common.

When dyeing a woven fabric formed of these fibers, it is necessary to appropriately select and use a dye corresponding to the characteristics of each fiber.

This is a serious problem particularly in a blended product composed of easily dyeable fibers and hardly dyeable fibers, such as a blended fabric made of a blended yarn of cotton and polyester,
When such a blended woven fabric is directly dyed with a hydrophilic dye such as a dye, color unevenness occurs, resulting in a marked decrease in commercial value.

This is now a common technical knowledge in this field, that is, a hydrophilic dye such as a direct dye is used for a blended fabric made of easily dyeable cotton and hardly dyeable polyester fiber. No attempt has ever been made to dye and commercialize it.

Therefore, at present, these mixed-spun fabrics are colored (dyed) by a method of applying a mixture obtained by mixing a pigment and a synthetic resin onto the cloth surface.

However, the woven fabric dyed with the above-mentioned pigment has a problem that the cloth surface becomes hard and the touch becomes poor because the cloth surface is coated with the mixture of the pigment and the synthetic resin. is there.

When a woven fabric dyed with such a mixture of a pigment and a synthetic resin is subjected to a raising process, fluffing is caused by the mixture of the pigment and the synthetic resin applied on the surface. Therefore, it is possible to raise only a small amount of hair, and it is meaningless to apply a raising processing to such a fabric.

That is, when colored in this way, the fiber surface is hardened by the mixture of the pigment and the synthetic resin, and the fiber coating process is carried out, so that the pigment applied to the fiber surface is scraped off. There is a problem that even if it is napped, it cannot be napped a little and the value as a woven fabric cannot be found.Therefore, a textile product made by napping a processed cloth dyed with a mixture of a pigment and a synthetic resin is The reality is that it has not been commercialized.

In order to solve such a technical problem, the present inventor diligently studied to improve the quality of the woven fabric made of the blended yarn of the prior art into a higher quality one, and repeated a number of trial productions and tests. The present invention has been completed.

That is, the inventor of the present invention maintains the surface flexibility of a woven fabric by dyeing a polyester / cotton blended woven fabric with a hydrophilic dye such as a direct dye or an acid dye, and then dyes this woven fabric. On the other hand, it has been found that, by carrying out a raising process, raising of short hairs such as the surface of a peach fruit can be achieved, and a raised fabric which has a very soft feel and expresses a texture like a backskin.

When the present inventor dyes a polyester / cotton blended fabric with a hydrophilic dye such as a direct dye or an acid dye, the cotton is dyed, while the polyester fiber is dyed at all or only slightly. As a result, when the woven fabric after dyeing is subjected to a raising process, the raised fluff not only buffers the uneven color, but also develops a very soft and gentle color tone. It was also found that the raised fabric is given a high-class feeling.

Further, when the polyester / cotton blend spun fabric is dyed with a hydrophilic dye, the present inventor dyes the cotton side and the polyester side is not dyed sufficiently, so that the overall color tone is a unique marbling tone. It has been found that a high-quality feeling can be expressed by the synergistic effect of the texture of the soft peach surface and the color tone of marbling by finishing the color tone of this.

In particular, the inventors of the present invention have found that polyester / cotton blended and spun woven fabrics are extremely inexpensive, and that the respective functions and abilities possessed by the respective fibers act synergistically to maintain heat retention,
It was also found that the fabric can be an excellent fabric having higher hygroscopicity, moisture transpiration, adaptability to human body, feeling of use, adaptability to body shape and the like.

In addition, the present inventor takes advantage of the fact that the polyester / cotton blended woven fabric is lighter in weight than the cotton woven fabric, dries quickly after washing, and does not require ironing if the fabric is conditioned and dried. It is a raised woven fabric that is suitable for use in the winter, and the dye is allowed to penetrate into the cotton side (cotton fiber of the mixed spinning yarn) without using the mixture of pigment and synthetic resin, which was the conventional dyeing method. By using a hydrophilic dye that does not sufficiently adsorb to (polyester fiber of blended yarn), the original softness of the fiber is maintained, and this is napped to create a unique texture with short hair like a peach surface. We obtained the knowledge that it will become a textile product that does.

The present invention has been completed on the basis of the above findings, in which a woven fabric having a blended yarn composed of polyester fibers and cotton as a constituent component is dyed with a hydrophilic dye and then napped. Therefore, it is extremely inexpensive and has excellent heat retention, hygroscopicity, moisture transpiration, adaptability to human body, feeling of use, and feeling of body that each function and ability possessed by polyester fiber and cotton work synergistically. It is an object of the present invention to provide a polyester fiber / cotton mixed-spun brushed woven fabric capable of exhibiting a new texture and color tone while improving or maintaining the conformability to the shape and the like.

According to the present invention, a polyester / cotton blend spun fabric is dyed with a hydrophilic dye and then napped, so that it is much lighter than a cotton woven fabric and dries quickly after washing.
Furthermore, if you adjust the shape and dry it, you do not need ironing,
The purpose is to provide a textile product that is easy to handle and meets the needs of consumers.

The present invention also provides beddings and interior textile products formed from the polyester fiber / cotton blended and raised woven fabric in order to make the best use of the characteristics of the polyester fiber / cotton blended and woven fabric. The purpose is to do.

[0031]

In order to achieve the above object, in a polyester fiber / cotton mixed-spun raised fabric according to the present invention, a mixed-spun fabric having a mixed yarn composed of polyester fiber and cotton as a constituent component. The blended spun fabric is characterized in that it is dyed or printed with a hydrophilic dye and then napped.

In the polyester fiber / cotton mixed napped woven fabric according to the present invention, the polyester fiber has a dense fiber structure, and with a hydrophilic dye, the dye is difficult to sit and does not dye at all or exhibits difficulty dyeing. As a result, it has the property that it cannot be dyed unless it is a special dye such as a pigment.

On the other hand, in the polyester fiber / cotton blended and raised woven fabric according to the present invention, cotton has a coarse fiber structure, so that the dye easily diffuses in the fiber and is excellent in dyeability, and the direct dye or the acid dye is used. It has the property of being easily dyeable with other hydrophilic dyes (easy dyeing property).

In the present invention, the use of polyester fiber and cotton is preferable because the unique texture and color tone are suitably exhibited and the raw material cost is low.

The method of mixing the polyester fiber and the cotton is not particularly limited, and a known blending method can be preferably used. For example, polyester mixed in a desired ratio at the raw material stage. A fiber and cotton may be mixed-spun, or a sliver (shin) made of polyester fiber and a single fiber of cotton and mixed by a kneading machine may be used.

When the blended yarn according to the present invention is formed by adopting the blending method using a kneading machine, the thickness and the blending ratio are eliminated, and each fiber becomes uniform, so that the quality is stable,
In addition, since both fibers are intricately entangled with each other, neither separation occurs due to long-term use, nor does each fiber deviate. It is also desirable because it will not lose its resilience even after long-term use.

In the present invention, regarding the mixing ratio of the polyester fiber and the cotton, the polyester fiber is preferably 40 to 80% by weight and the cotton is 60 to 20% by weight, more preferably the polyester. The fiber content is 45 to 70% by weight and the cotton content is 55 to 30% by weight.

80% by weight of polyester fiber mixed
If it exceeds the above, the mixing ratio of cotton becomes too small, resulting in poor color development, monotony overall color tone, poor texture, and further, the raised state deteriorates even after the raising step described below. However, so-called pilling (pillage) frequently occurs, which is not preferable.

On the other hand, the mixing ratio of polyester fiber is 40
If it is less than 10% by weight, the mixing ratio of cotton will increase, so the color development and color tone will improve, but the textile product may become heavier and the flexibility and wash resistance may decrease, and wrinkles will be noticeable. Therefore, it is not preferable.

In particular, using the polyester / cotton blended woven fabric raised cloth according to the invention, for example, a futon cover (size 15)
0cm × 210cm standard product 5% polyester 5% cotton 5
(0%) weighs 680 g, and a traditional cotton woven raised fabric (100% cotton) is used for futon cover (size 1).
50cm x 210cm standard product) Weight is 10 when manufactured
The weight is 50 g, which is about 35% lighter than cotton alone (same thread thickness).

Recently, the weight of beddings has been further reduced, and down futons have become the mainstream, and the standard weight is about 3000.
Approximately 4,000 g of standard futon using cotton wool
It is possible to reduce the weight by about 1000 g compared to kg.

As the consumer's needs are oriented toward light weight as described above, it is also a demand of the times to reduce the weight of the futon cover and the futon side to meet the consumer's needs. From this viewpoint as well, the mixing ratio of polyester fibers is Is preferably less than 40% by weight.

Further, in the polyester / cotton blend spun fabric according to the present invention, the polyester fiber of 40 to 80% by weight and the cotton of 60 to 20% by weight make the obtained fiber product low in price. It is clear that the consumer's willingness to purchase is improved in consideration of the superiority, lightness, washing resistance, and the product strength that has the same texture.

Next, in the present invention, a woven fabric having a blended yarn composed of polyester fiber and cotton as its constituent components is dyed with a hydrophilic dye. As this hydrophilic dye, a water-soluble dye is used. It is not particularly limited as long as it is, specifically, for example, as a hydrophilic dye, a direct dye or an acid dye which is easily soluble in water can be preferably used, and like the bad dye, A water-soluble dye that can be used by solubilizing it in an alkaline bath by reduction can also be used.

As for the dyeing method, a known dyeing method can be preferably used, and the "staining" in which the spun blended yarn is dyed in advance and then the blended spun fabric is formed.
Or, it may be "post-dyeing" in which the mixed-spun fabric is formed and then dyed. More specifically, as a specific dyeing method, for example, a dipping method, a textile printing method, a casting method, Well-known dyeing methods such as mist-blow dyeing and rubbing dyeing can be preferably used.

As described above, when a hydrophilic dye is used in the present invention, cotton in the present invention is mainly hydrophilic, so that it is preferably dyed with a hydrophilic dye, while polyester fiber in the present invention is mainly lipophilic. Therefore, it is poorly compatible with the hydrophilic dye and is hardly dyed.

That is, when a woven fabric having a blended yarn composed of polyester fiber and cotton as its constituents is dyed with a hydrophilic dye, uneven dyeing occurs mainly in the state where only cotton is dyed. In the present invention, by performing a raising process on the woven fabric intentionally causing this uneven dyeing, it is possible to raise short hairs such as the surface of the peach fruit, resulting in an extremely pleasant touch and a backskin. The raised fluff not only buffers color unevenness but also develops a very soft and gentle color tone, giving the raised fabric a high-class feel.

In the present invention, it is not necessary to use a special device or method for this raising process, and a known raising process, for example, a raising machine equipped with thistle seeds or needle cloth, is used to scrape the fluff. A method of causing it can be suitably used.

By the way, with respect to the polyester fiber / cotton blend napped woven fabric according to the present invention having many characteristics as described above, for the purpose of giving further added value, anti-mite treatment, anti-bacterial treatment, deodorant treatment , At least one selected from hinokitiol addition processing, chitosan addition processing or collagen addition processing,
It is preferable to use the thus-treated material after forming it into clothing or the like, since it keeps a hygienic state due to antibacterial / anti-mite effects and the like, is gentle on bare skin, and improves the feel of the skin. Among them, hinokitiol is known to have an effect of relaxing the mind of a person who can be obtained by bathing in the forest, and thus can also alleviate stress and the like.

The polyester fiber / cotton mixed napped woven fabric according to the present invention has the characteristics as described above. Generally, the polyester fiber / cotton mixed napped woven fabric is used as a material for bedding. In addition, a textile product (secondary product or tertiary product) such as an interior textile product is formed, and thereby, the characteristics of the polyester fiber / cotton blended and spun woven fabric are utilized in a specific product.

Hereinafter, the polyester fiber / cotton blended and raised woven fabric of the present invention as described above is used as a raw material, and the fiber product utilizing this property is not particularly limited, but particularly bedding and interior fiber. It is preferable to apply it to products because the added value is improved.

The bedding is not particularly limited, but specific examples thereof include futon side cloths, towelettes, sheets, and covers.

The interior textile product is not particularly limited, but specific examples thereof include curtains, carpets, upholstery, wallpaper, table cloth and the like.
