Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warp knitted blanket generally called a Meyer blanket and a method for producing the same.

[0002]

2. Description of the Related Art In recent years, a warp knitting blanket, which has become the mainstream in the field of blankets, is a double knitted fabric knitted using a double Russell warp knitting machine. From the center, the cut pile surface is fluffed, and the doubled blanket made by laminating both cut knit fabrics with the fibrillated pile surface facing up, or fluffing both sides of each of the two cut knit fabrics Also, a single blanket having pile layers on both sides made by raising the brush is known.

A conventional warp knitted blanket of this type uses a heat-shrinkable fiber such as an acrylic fiber yarn as the pile yarn, shrinks the pile yarn by steaming and heat treatment, develops bulky properties, and is bulky and dense. Using a non-heat-shrinkable cellulosic fiber yarn such as a cotton layer or a non-heat-shrinkable cellulosic yarn as the pile yarn to have a natural material texture that matches the natural taste and to be washable at home. And, using a blended or twisted yarn of the heat-shrinkable fiber and the non-heat-shrinkable fiber, which is intended to improve the hygroscopicity, lightness, and the like, to make the characteristics of both fibers complex and manifest. There exist such things.

[0004] However, regardless of the type of pile yarn used in the conventional blanket, the surface feel of the pile layer is a flat feeling, and it is not always possible to realize a suitable feel depending on the season of use. In addition, the dyeing pattern by printing was rather uniform and had little change, and it was difficult to obtain satisfactory satisfaction in terms of amusement.

[0005]

SUMMARY OF THE INVENTION The present invention provides a pile layer having a flat feeling in appearance, a ridge-like unevenness in the tactile sensation in the tactile sense, a unique excellent touch, and a dyeing effect. Even in the pattern, it is possible to express a highly interesting design with a unique change by ordinary printing processing,
Moreover, it is an object of the present invention to provide a warp knitted blanket which is excellent in washing resistance and further excellent in heat retention characteristics and a method for producing the same.

[0006]

SUMMARY OF THE INVENTION The present invention uses two or three or more types of pile yarns having different heat shrinkage rates, and these are used to form a warp knitted fabric by a double Russell warp knitting machine. It shall be knitted alternately or in a predetermined permutation arrangement for every two or more wales of a plurality of wales, and then heat-shrink the pile yarns of the heat-shrinkable fibers by a heat treatment, and then apply a hair treatment and / or a raising treatment. This is characterized in that a pile portion having an irregular height is formed by using the same method, and then the surface of the pile layer having a height difference is finished to a uniform flat surface by a shearing process.

According to the first aspect of the present invention, in a blanket made of a warp knitted fabric knitted by a Raschel warp knitting machine, the pile has a heat shrinkage having a different boiling water shrinkage in a range of 15 to 30%. The heat-shrinkable fiber yarn and the non-heat-shrinkable fiber yarn are alternately arranged every two or more wales of two or more wales. The pile of the heat-shrinkable fiber yarn is heat-shrinked by heat treatment to form a dense geological pile portion by shortening and bulkiness, and the heat-shrinkable fiber yarn and the non-heat-shrinkable fiber A warp knitted blanket having a textured touch, characterized in that the surface of a pile layer formed of yarn is finished to a flat surface by a shearing process.

In the blanket having such a configuration, the surface of the pile layer has a smooth flat surface in appearance, and the apparent surface is the same as that of a conventional warp knitted blanket. In addition, it is possible to have a sense of parallel unevenness in the longitudinal direction. In other words, the bulky dense pile portion made of the heat-shrinkable fiber yarn shows relatively large rebound resilience to the pressure from the surface side and does not easily buckle, whereas the non-heat-shrinkable fiber yarn Since the pile portion is constituted by a group of straight hair-like fibers, it is relatively easily deformed with a tendency to fall down when pressure is applied. For this reason, in the tactile sensation, the dense pile portion of the heat-shrinkable fiber yarn perceives a ridge-shaped ridge, and the soft soft pile portion of the non-heat-shrinkable fiber yarn perceives a dent. It becomes what has. The uneven feel makes the feel of the blanket unique, enhances the refreshing feeling and refreshing feeling at the time of use, and can provide a comfortable use feeling especially in spring and autumn. Furthermore, the non-heat-shrinkable fiber yarn can maintain a sufficient air layer in the soft pile portion, and can have a more excellent heat retaining property than a general cotton blanket.

In addition, the two pile portions appear as slightly different in appearance. In particular, based on the difference in dyeing characteristics due to the heterogeneity of the fibers used, it is possible to easily express the different phase difference in the dyeing concentration, and to express the subtle stripe pattern on the pile layer surface with the above-mentioned plane pile portion. It can be made to be highly aesthetic and entertaining.

[0010] Furthermore, the bulky dense geological piles exhibiting bulkiness are present adjacent to the soft soft piles made of non-heat-shrinkable fiber yarns alternately, so that both piles can be used. The inherent disadvantages of the fibers complement each other, and a composite effect of both fibers is obtained. For example, a unique feel different from the pile layer made of a single material can be obtained, and in the case of a blanket made of only a non-heat-shrinkable fiber pile, the shape change after washing is remarkable, but the heat-shrinkable fiber The remarkable shape change described above is suppressed by the mixture of the pile portions, and the washing resistance can be further improved.

In the invention of claim 2, a thermoplastic synthetic fiber yarn having a boiling water shrinkage of 15 to 40% is used as the heat shrinkable fiber yarn, and a boiling water shrinkage ratio of 0 to 0 is used as the non-heat shrinkable fiber yarn.
10% of the cellulosic fiber yarn is used.

[0012] In this configuration, the alternately arranged pile sections that are alternately arranged in the warp direction have mutually different dyeing properties, and express a unique color effect and pattern rich in interest in the appearance after dyeing. be able to.

According to a third aspect of the present invention, the heat-shrinkable fiber yarn is an acrylic fiber yarn, and the non-heat-shrinkable fiber yarn is a cotton yarn.

By selecting the pile yarn material, it is possible to secure the advantage in the cost of the pile yarn material and the selective easy dyeing between different kinds of pile yarns, and to achieve the above-mentioned effects more advantageously.

According to a fourth aspect of the present invention, three types of pile yarns having mutually different heat shrinkage rates are used. That is,
Three types of piles, heat-shrinkable fiber yarns with different boiling water shrinkage ratios, low heat-shrinkable fiber yarns by blending or twisting heat-shrinkable fibers and non-heat-shrinkable fibers, and non-heat-shrinkable fiber yarns The heat-shrinkable fiber yarn, the low heat-shrinkable fiber yarn, and the non-heat-shrinkable fiber yarn are knitted in a predetermined permutation arrangement for every two or more wales. At the same time, the heat-shrinkable fiber yarn and the low heat-shrinkable fiber yarn pile are thermally shrunk by heat treatment, and the former forms a dense geological pile portion by shortening and bulkiness, while the latter forms a medium density geological pile. A part is formed, and the surface of the pile layer made of the three kinds of pile yarns is finished to a flat surface by a shearing process.

In the present invention, in addition to the effects of the first aspect of the present invention, a dense geological pile made of heat-shrinkable fiber yarn and a soft soft pile made of non-heat-shrinkable fiber yarn are provided. In the form interposed between the two fiber yarns, due to the presence of a medium-density geological pile portion composed of low heat shrinkable fiber yarns exhibiting an intermediate heat shrinkage between the two fiber yarns, it has a smoother uneven texture in the warp direction Can be done. That is, the medium-density geological pile portion interposed between them reduces the sudden change in tactile sensation between the convex haptic portion due to the dense geological pile portion and the concave haptic portion due to the soft pile portion. As a result, the unevenness in the tactile sensation can be made gradual, and the sensation can be further enhanced.

In addition, in the dyeing effect, the color change between the dense geological pile portion and the soft geological pile portion can be gradually made to have a so-called gradual change, Visually, it can be made to have a higher quality.

Furthermore, the unusual tendency of the dense geological pile portion to expand can be suppressed by the presence of the medium density geological pile portion. In other words, it is possible to prevent the flexible pile portion from being excessively pressed from both sides by the dense geological pile portion that tends to spread strongly due to the increase in bulk, and the width thereof becomes extremely narrow. Therefore, it is possible to prevent a streak-like wrinkle from appearing on the pile layer due to this phenomenon.

According to a fifth aspect of the present invention, there is provided the blanket manufacturing method according to the first aspect, wherein the Raschel warp knitting machine comprises:
By using two kinds of pile yarns of a heat-shrinkable fiber yarn and a non-heat-shrinkable fiber yarn having different boiling water shrinkage ratios in the range of 15 to 30%,
And knitting a warp knitted pile fabric in which a plurality of these two types of pile yarns are knitted alternately for each of a plurality of wales of at least 2 wales and a plurality of wales; After heat shrinking the pile yarn made of the yarn, applying a hair treatment and / or raising treatment to form a pile layer having an irregular height, and then performing a shearing process to finish the surface of the pile layer to a flat surface. It is characterized by the following.

Thus, a warp knitted blanket having the many advantages according to the first aspect can be easily manufactured.

The invention according to claim 6 is the blanket manufacturing method according to claim 4, wherein the Raschel warp knitting machine
Heat shrinkable fiber yarns having different boiling water shrinkage ratios, low heat shrinkable fiber yarns by blending or twisting heat shrinkable fibers and non-heat shrinkable fibers, and non-heat shrinkable fiber yarns A warp knitted pile fabric in which a plurality of these three types of pile yarns are woven in a predetermined permutation arrangement for each of a plurality of wales of 2 to more than a few wale is knitted using a pile yarn, and the pile ground is subjected to heat treatment. The heat-shrinkable fiber yarn and the low heat-shrinkable fiber yarn are shrunk to perform a hair treatment and / or a raising process to form a pile layer having an irregular height. Is characterized in that the surface is flattened.

Thus, a warp knitted blanket having the many advantages according to the fourth aspect can be easily manufactured.

[0023]

1 to 3 show one embodiment of the present invention using a warp knitted fabric knitted using two kinds of pile yarns having different boiling point shrinkage rates.

FIG. 1 is an external perspective view showing the entire external appearance of the warp knitting blanket (1), and FIG. 2 is a schematic sectional view showing the arrangement of pile yarns (2) and (3) with respect to the ground structure (4). FIG. 3 is a schematic cross-sectional view of a product state in which the pile layer (5) has been subjected to hair handling and raising, and the surface of the pile layer (5) has been sheared and cut into a flat surface.

As the knitting yarn constituting the ground knitting structure (4), generally, polyester filament yarn is suitably used, but the invention is not limited to this. Cellulose fiber yarns such as other synthetic fiber yarns and cotton yarns may be used.

As the pile yarns (2) and (3), two types of heat-shrinkable fiber yarns and non-heat-shrinkable fiber yarns having mutually different boiling water shrinkage ratios in the range of 15 to 30% are used in combination. You. If the difference between the boiling water shrinkage ratios is less than 15%, the texture of the pile layer (5) desired by the present invention cannot be provided with a sufficient uneven texture. Conversely, those having a difference in boiling water shrinkage of more than 30% are economically disadvantageous because the amount of cut fibers when finishing the surface of the pile layer (4) to a flat surface increases. A preferable range of the difference in the relative boiling water shrinkage is about 20 to 25%.

As one pile yarn (2) made of a heat-shrinkable fiber yarn, a thermoplastic synthetic fiber yarn having a boiling water shrinkage of 15 to 40% is used. Such synthetic fiber yarns are filament yarns or bulky processed yarns composed of various synthetic fibers such as polyamide-based, polyester-based, polyacrylic-based, polyolefin-based, polyvinyl chloride-based, and polyvinylidene chloride-based or composites having latent crimpability. Filament yarn and the like are included. Preferably, for example, the boiling water shrinkage is 20 to 25.
% Acrylic fiber yarn is used.

The pile yarn (3) made of the specific heat-shrinkable fiber yarn includes spun yarn made of various cellulose yarn fibers such as cotton, hemp, rayon, and acetate, and filanto, but has a boiling water shrinkage of 0 to 0. As long as the content is 10%, a thermoplastic synthetic fiber yarn can be used without any trouble. From the viewpoints of material cost, pile feel, ease of washing, etc., use of cotton yarn is most preferably recommended.

The two types of pile yarns (2) and (3) having different heat shrinkage rates are, as shown in FIG. 2, two or more wales based on the warp extending in the warp direction of the warp knitted fabric. It is necessary that two or more wale units (4 to 6 wale units) be sequentially knitted in an alternate arrangement in units of two or more. In the case of the alternate arrangement one by one for each wale, it is not possible to provide the pile layer (5) of the product blanket with a sufficient desired uneven texture. Further, in the case of the alternate arrangement of a large number of pieces exceeding several wales, the surface texture of the pile layer (5) is such that a large uneven undulation can be sensed and lacks the tactile sensation. FIG.
The illustrated example of FIG. 3 shows a preferred embodiment in which the heat-shrinkable pile yarns (2) and the non-heat-shrinkable pile yarns (3) are arranged alternately in pairs. The number of pile yarns may be different from each other. For example, two heat-shrinkable pile yarns (2) and three or four non-heat-shrinkable pile yarns (3) may be alternately arranged, or the arrangement may be reversed. .

The blanket of the above embodiment according to the present invention is manufactured by using a double Russell warp knitting machine typified by a Karl Meyer knitting machine by a predetermined arrangement of the pile yarns (2) and (3). Is knitted, the center of the pile yarn reciprocating between the front and back knitted fabrics of the double knitted fabric is cut at the center, and then the separated pile knitted fabric is processed into a product by an ordinary method. That is, the product is subjected to a heat treatment, preferably a shrinking treatment (relaxation treatment) by steam heat treatment, a dyeing treatment with a screen glint, a hair treatment and / or a raising treatment, a shearing treatment for flattening the pile layer surface, and the like.

The shrinking process by heat treatment may be performed in the same step as the dyeing, but is an essential step in the practice of the present invention. Due to this heat treatment, the pile yarn (2) made of the heat-shrinkable fiber yarn undergoes a large heat shrinkage as shown in FIG. 2 to exhibit a bulky property, and as shown in FIG. (5A) is formed. On the other hand, the pile yarn (3) made of the non-heat-shrinkable fiber does not shrink at all or hardly shrinks, and retains the fiber shape as it is, and forms a soft and soft geological soft pile portion (5B). Form.

The two types of pile yarns (2) and (3) are
In the dyeing process, they show heterochromatic properties between each other. For example, in the case of dyeing with a cationic dye, even when the surface of the knitted fabric is dyed in a single color, the pile yarn (2) portion composed of the heat-shrinkable fiber yarn is dyed well, while the non-heat-shrinkable fiber is not dyed. The pile yarn (3) made of is hardly dyed or relatively lightly dyed, and a unique dyeing pattern effect due to shading changes appears on the surface.

The heat-treated and dyed knitted fabric is subsequently subjected to a bristle treatment on the pile surface side, and if necessary, a brushing process on the opposite surface to form a fibrillated pile layer (4). The pile layer (4) after the hair handling and the brushing is
Due to the difference in the heat shrinkage of each pile yarn (2) (3) due to the heat treatment, the heights become uneven. So then,
By the shearing process, the surface of the pile layer (5) is finished to a flat surface to obtain a product. The finished pile layer (5) has a dense pile portion (5) formed by the heat-shrinkable fiber pile yarn (2) due to the bulkiness of the pile yarn.
A) shows a strong spreading tendency in the plane direction. For this reason, it occupies a wider area than the soft pile portion (5B) formed by the other non-heat-shrinkable fiber pile yarn (3).

FIGS. 4 and 5 show another preferred embodiment of the present invention. In this embodiment,
As the pile yarn, three types of pile yarns (2), (3) (3) (a heat-shrinkable fiber yarn similar to the above, a non-heat-shrinkable fiber yarn, and a low heat-shrinkable fiber yarn exhibiting intermediate heat shrinkability thereof) 6) are used. It is preferable that the pile yarn (6) made of the low heat shrinkable fiber yarn fits comfortably with the other pile yarns (2) and (3), and the heat shrinkage of the surface pile yarns (2) and (3) is improved. Blended or cross-twisted yarns of fibers and non-heat-shrinkable fibers are preferably used.

Then, these three types of pile yarns (2)
In (3) and (6), as described above, a plurality of wales are arranged in a predetermined permutation for each of a plurality of wales of 2 or more wales. In the illustrated example, three types of pile yarns (2), (3), and (6) are knitted in a sequential arrangement two by two, and the pile layer (5) has a dense geological pile portion (5A). , A soft pile section (5B) and a medium-density geological pile section (5C). Of course, these arrangements can be changed in other ways, for example, the heat-shrinkable fiber pile yarn (2) and the non-heat-shrinkable fiber pile yarn (3) are all interposed between the heat-shrinkable fiber pile yarn (3) and the low heat-shrinkable fiber pile yarn (3). The pile yarn (6) may be arranged. In this case, the low heat shrinkable fiber pile yarns (6) may be arranged one by one between the other pile yarns (2) and (3). Therefore, in the configuration defined in claims 4 and 6, the specification of “every plural number of wales” means that, for the low heat shrinkable fiber pile yarn (6), a plurality of pile yarns (2) and (3) are adjacent to each other. It shall be used in a sense including the case where the low heat shrinkable fiber pile yarn (6) is interposed.

Other configurations, manufacturing steps, and the like in the embodiment of FIGS. 4 and 5 are the same as those in the embodiment of FIGS.

Had. In the appearance of the surface of the pile layer (5), the width of the dense pile portion (5A) of the heat-shrinkable fiber pile yarn (2) is about 12 mm, whereas the non-heat-shrinkable fiber pile yarn (3) is used. The width of the flexible pile part (5B) is as narrow as about 5 mm, and the former pile part (5A) is dyed relatively darker than the latter pile part (5B), showing a subtle color change. , A unique striped pattern. In addition, it was confirmed that the former pile portion (5A) gave a convex ridge feel, and the latter pile portion (5B) gave a concave ridge feel.

In addition to the face pile yarns (2) and (3) of Example 1, as a third low heat shrinkable fiber pile yarn (6), a cross of an acrylic fiber yarn No. 32 and a cotton yarn No. 20 single yarn is used. Using twisted yarns, these three types of pile yarns (2) (3) (6)
The double knitted fabric was knitted by sequentially knitting two pieces for each wale.

A blanket product was manufactured in the same manner as in Example 1 except for the other components and manufacturing steps.

In this blanket product, the pile layer (5)
Is a dense geological pile part (5A) made of heat shrinkable fiber pile yarn (2), a medium density pile part (5C) made of low heat shrinkable fiber pile yarn (6) made of twisted yarn, and a non-heat shrinkable fiber yarn (3). ), The soft pile portions (5B) are present in the sequential arrangement, so that a smooth uneven touch can be sensed as compared with that of the first embodiment. Also, the dyeing effect is such that the medium density pile part (5C) interposed between the dense pile part (5A) and the soft pile part (5B) shows an intermediate dyeing density, and the gradation tone is subtle. This indicates a striped pattern with a large change in density.

In each of the first and second embodiments, the case of using one piece of warp knitted blanket was shown. However, two pieces of the center-cut single-sided pile knitted fabric were piled up with their pile faces outside. The present invention can be applied to a double blanket in the same manner.

That is, the medium-density geological pile portion interposed between them reduces the sudden change in tactile sensation between the convex haptic portion due to the dense geological pile portion and the concave haptic portion due to the soft pile portion. As a result, the unevenness in the tactile sensation can be made gradual, and the sensation can be further enhanced.

In addition, with regard to the dyeing effect, the color change between the dense geological pile portion and the soft geological pile portion can be made to have a gradual change, and a so-called gradual change can be obtained. Visually, it can be made to have a higher quality.

Furthermore, the unusual tendency of the dense geological pile portion to expand can be suppressed by the presence of the medium density geological pile portion. In other words, it is possible to prevent the flexible pile portion from being excessively pressed from both sides by the dense geological pile portion that tends to spread strongly due to the increase in bulk, and the width thereof becomes extremely narrow. Therefore, it is possible to prevent a streak-like wrinkle from appearing on the pile layer due to this phenomenon.
