Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single piece of warp knitted single blanket generally called a New 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. Above all, this single piece of warp knit single blanket is lightweight and can be manufactured and provided at relatively low cost. is there.

Conventionally, such a warp knit single blanket is generally manufactured as follows.

[0004] That is, a double warp knitted fabric knitted by a double Russell knitting machine is center-cut from the center of a pile yarn reciprocating between the front and back knitted fabrics to produce a single-sided pile knitted fabric. And, using this one-sided pile knitted fabric as a material,
First, after the pile pile of cut piles is printed to a desired color and pattern by an automatic screen printing machine,
The cut pile surface is subjected to a separating process, and the printed pile yarn is defibrated to form a fine fluffy surface pile layer, while the single-sided pile knitted fabric is subjected to a brushing process on a back side having no cut pile, A part of the pile yarn entangled with the ground structure is scraped and fluffed to form a back pile layer. After that, according to a standard method, it is commercialized after finishing processing such as shirring and polisher for hair alignment.

[0005]

However, the warp-knit single blanket obtained by the above-mentioned manufacturing method has the following problems inherent to it.

That is, after printing on the cut pile surface,
Since the back side is brushed, the pattern of the back side pile layer formed by scraping a part of the pile yarn on the back side is always the same as the pile layer on the front side. On the back side, a relatively remarkably unclear blurred pattern appears, which is likely to be dirty.

[0007] For this reason, the surface pile layer side on which clear printing is applied is always visually recognized as the front surface of the blanket, but in practice, many users use this surface pile layer when using this surface. With the outer side facing out and the back pile layer side facing the skin side. However, since the back pile layer that hits the skin surface is formed by raising, the pile density is relatively low, and not only the feel is inferior, but also the pile layer has inferior abrasion resistance.
There was a problem that the peeling phenomenon was apt to occur, and the good service life of the blanket was shortened.

Further, since the cut pile is separated and defibrated after printing, the degree of defibration tends to be insufficient due to the effect of the remaining printing paste, and as a result, the pile layer has insufficient air retention. Another drawback is that it lacks warmth.

An object of the present invention is to provide a new warp knit single blanket which can solve the above problems. That is, hair loss and peeling hardly occur on the skin side during use, so that durability can be increased, and unclear printed patterns with a blurred appearance on the skin side do not appear, and the patterns on the front and back are strictly different. It is an object of the present invention to provide a single-layer warp knit blanket capable of expressing a sense of quality as a material, and being warm and excellent in drapability, and a method for producing the same.

[0010]

SUMMARY OF THE INVENTION The present invention has the unique feature that the above-mentioned purpose can be achieved by making a conventional New Meyer blanket used upside down. It was completed based on the idea.

The invention according to claim 1 is directed to a single-piece pile knitted fabric obtained by center-cutting a double warp knitted fabric from the center of a pile yarn reciprocating between front and back knitted fabrics. In producing the warp knitted single blanket, the back side of the single-sided pile knitted fabric having no cut pile is subjected to a raising process in advance to form a back side pile layer, and thereafter, the back side pile layer is subjected to printing treatment to perform a predetermined process. The gist of the present invention is a method for manufacturing a single-layer warp knitted blanket, characterized in that a beautiful decorative surface is provided on the back side by printing the pattern or the like.

[0012] In the warp knit single blanket according to the present invention, a clear pattern is printed on the back side pile layer formed on the back side by brushing, and the face is formed on a decorative surface. Therefore, the user recognizes the back pile layer side as the front side of the blanket, and in many cases, turns the surface to the outside and uses the opposite surface pile layer side as the surface to be brought into contact with the skin. Here, since the surface pile layer side corresponding to the skin is formed by the separation processing from the cut pile, the density of the fiber pile is high and the pile layer having a good finished state is formed. A pile layer in a so-called good fabric formation state is formed. For this reason, even if it repeatedly comes into contact with the human body and is repeatedly subjected to friction, the degree of hair loss and peeling is low, and the pile layer is unlikely to be thin. Therefore, the durability of the blanket itself can be increased.

Further, as described above, since the surface pile layer has a high pile density of the fiber group and is defibrated by loosening without being subjected to a printing process,
There is no adverse effect such as a decrease in the degree of fibrillation due to the remaining printing paste. Therefore, the degree of defibration is sufficiently performed, and a large amount of air layers can be included, so that it is possible to further improve the feeling of skin and the heat retaining effect at the time of use.

According to a second aspect of the present invention, after the printing of the back pile layer, the cut pile surface on the front side is separated. By adopting such a processing procedure, the printing process of the backside pile layer in the previous process can be performed at a stage where the pile surface on the front side remains the pile yarn. For this reason, it is not necessary to pay special attention to handling so as not to damage the surface pile layer during the printing process, and the printing process can be easily performed. Of course, if this advantage is sacrificed, the cut pile surface may be separated before printing the back pile layer.

According to a third aspect of the present invention, after printing the back pile layer, the surface on the back pile layer side is further subjected to a slight raising process. By this raising process, the lowering of the texture of the back pile layer due to the influence of the printing process is repaired, and the back pile layer having a good texture can be formed. Assuming that the brushing ratio of the backside pile layer in the final product is 100%, the sharing ratio in the brushing step after printing is approximately 5 to 20 in image.
%, Preferably about 8 to 12%. Therefore, the original brushing process performed before printing is 80 to
Needless to say, it is performed in the range of 95%.

According to a fourth aspect of the present invention, there is provided a method of manufacturing a blanket using a heat-shrinkable synthetic fiber yarn such as an acrylic fiber yarn as a pile yarn. In addition to this, in addition to the production method according to any one of claims 1 to 3, this method includes a step of previously performing a steaming heat treatment or a steaming heat treatment on a double warp knitted fabric used as a material or a single-sided pile knitted fabric after setter cutting. The main feature is that the process is carried out, and then the above-mentioned raising process is performed.
This steaming treatment may be performed alone, but is desirably performed in the counter-dyeing step. Before the raising process, the anti-dyeing process, that is, the dyeing process in the dye tank, the steam heat treatment for improving the fixing property of the dye, the washing process, and the drying process are performed, so that the finished color tone of the blanket can be adjusted to a desired good one. In addition, the steaming heat treatment imparts crimping properties and bulky properties to the synthetic fiber pile yarn, and suppresses fiber loss of the pile yarn and generation of fly wool during the raising process performed in the next step, and provides a good brushed pile. The formation of a layer becomes possible. In addition, since it is manufactured through two heat treatments of a steaming heat treatment and a printing treatment, a blanket having extremely excellent drapability can be manufactured.

The invention according to claim 5 specifies the structure of a warp knitted single blanket manufactured by the manufacturing method according to claim 1, and has a light weight characteristic based on a single warp knitted blanket. In addition, as described above, hair loss and peeling are less likely to occur and the durability can be excellent, and the design of the front and back surfaces and patterns different from those of the conventional New Meyer blanket have a unique design. Blankets may be provided. Furthermore, the heat retention can be further improved.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION The production of a single-sided pile knitted fabric used as a material is carried out by a conventional method as in the case of conventional products. That is,
Using a double Russell warp knitting machine, knit a double warp knitted fabric in which pile yarn reciprocates between a front knitted fabric and a back knitted fabric that are knitted away from each other, and center the pile yarn between the front and back knitted fabrics. The base fabric (10) is cut to form two single-sided pile knitted fabrics (1) in which cut piles (2a) of pile yarns (2) are arranged on one side of the base fabric (10).

One piece of New Meyer warp knitted blanket often uses an acrylic fiber yarn for the pile yarn. In addition, it is also possible to use a polyester thread, a nylon thread, or the like.

When such a synthetic fiber yarn is used as a pile yarn, a steam heat treatment or a heat treatment including a steam heat treatment is applied to the single-side pile knitted fabric (1) as shown in FIG. Perform the dyeing process. In the anti-dyeing step, the entire surface of the single-sided pile knitted fabric (1) is dyed white or light to improve the finished appearance of the blanket, and the synthetic fiber pile yarn (2) is crimped by steaming heat treatment. It is intended to allow the back brushing in the next step to be performed without any trouble.
Specifically, according to a conventional method, for example, using a continuous vat dyeing apparatus for dyeing, after dyeing, uniformly squeezed with a padder, and then steam-heated in saturated steam to promote fixing of the dye. After performing a washing treatment using a washing solution such as an anionic surfactant, dehydration and drying are performed.

The above-mentioned steaming heat treatment or anti-dyeing step is preferably performed on the single-sided pile knitted fabric (1) in the processing step as described above. Later, the center cut may be performed to obtain the single-sided pile knitted fabric (1).

When a non-heat-shrinkable natural fiber such as cotton yarn is used for the pile yarn, the steaming heat treatment and the anti-dyeing step are not necessarily required.

The single-sided pile knitted fabric (1) after the anti-dyeing step is subjected to a brushing process by a conventional method on the back side having no cut pile (2a), and a part of the pile yarn (2) is back-faced. By scraping to the side, the fibers of the pile yarn (2) form a fluffy back pile layer (3) as shown in FIG. This raising is about 9 times the raising state of the final product.
It is preferable to carry out the treatment in a range where the raising ratio is about 0%.

Next, a double-sided pile knitted fabric (11) as shown in FIG. 3 which has been subjected to the above-mentioned brushing is printed by an automatic screen printing machine. In this printing, the back pile layer (3) on the back side formed by the above-mentioned raising process is printed, and the cut pile (2a) on the other front side is printed.
In this case, the effect of printing is not affected as much as possible.
Specifically, the printing process uses a color paste of a cationic dye when the pile yarn (2) is an acrylic fiber yarn, and uses a reactive dye when the pile yarn (2) is a natural fiber such as cotton yarn. This is performed using glue. After the printing process, an appropriate heating temperature and time (for example, 100 ° C. ×
(30 minutes) to promote the fixation of the dye, and then the respective printing, washing, dehydration and drying steps are completed to complete the predetermined printing step. In FIG. 3, the colored portion of the pile layer by printing is indicated by reference numeral (4).

Next, the double-sided pile knitted fabric (11) that has been subjected to the printing process is subjected to a loosening process on the surface side, and the cut pile (2a) is defibrated, as shown in FIG. A surface pile layer (5) is formed as a layer.

Thus, the pile layers (5) are formed on both the front and back surfaces.
FIG. 4 having (3) and clearly printing the desired pattern or pattern by the colored portion (4) only on the back pile layer (3)
Although the double-sided pile knitted fabric (12) as shown in (1) is obtained, the back side pile layer (3) is preferably in view of the fact that the feeling is impaired by the effect of the printing process, and this back side pile layer (3) is preferred.
It is desirable to apply a slight loosening process or a slight re-raising process to the side surface so as to adjust the feeling and generate some new fluff. This re-raising process is preferably performed within a range of a processing rate of about 10%.

The pile knitted fabric after each of the above steps is subjected to finishing such as shearing or polisher on the pile layers (3) and (5) on the front and back surfaces, cut into a predetermined size, and then surrounded by a rim cloth ( 6) is sewn to complete a predetermined warp knit single blanket (A).

As shown in FIG. 1, the warp knitted blanket (A) manufactured by the method of the present invention has a predetermined clear pattern (14) by printing only on the back pile layer (3) side. The surface on the side of the surface pile layer (5) is formed in a white or light-colored solid color.

For this reason, the user visually recognizes the surface on the side of the back pile layer (3), which represents a beautiful decorative surface with a design pattern, as the front surface of the blanket. Therefore, in most cases, the user applies the surface with the back pile layer (3) side outside, and uses the plain surface pile layer (5) side as the surface in contact with the human body. It is.

[0030]

The blanket produced by the method according to claim 1 of the present invention is, in use, almost always with the back pile layer (3) facing up and the front pile layer (5) as described above. The use mode in which the side is the back side is selected, whereas the front pile layer (5) is the cut pile (2).
By being formed by the separating process from a), a good pile layer having a high fiber density and excellent fixation to the base fabric (10) is formed in a finished state. For this reason, even if it comes into contact with the human body and receives repeated friction,
The degree of occurrence of hair loss and peeling is low, and the pile layer is unlikely to become thin. Therefore, the durability of the blanket itself can be increased.

Further, as described above, the surface pile layer has a high pile density of the fiber group and is formed by defibration by loosening without being subjected to printing.
There is no adverse effect such as a decrease in the degree of fibrillation due to the remaining printing paste. Therefore, the degree of defibration is sufficiently performed, and it is possible to include many air layers, and it is possible to further excel in the feeling of skin and the heat retaining effect when used.

Further, in the invention according to claim 2, since the printing process of the back pile layer is performed at a stage where the pile surface on the front side remains the pile yarn, the front pile layer is damaged during the printing process. It is not necessary to pay special attention to the handling so that the printing process can be easily performed, which is advantageous in production.

According to the third aspect of the present invention, after printing the back pile layer, the surface on the side of the back pile layer is further subjected to a slight raising process. Can be repaired, and a back pile layer having a good feeling can be formed.

According to a fourth aspect of the present invention, a method of manufacturing a blanket using a heat-shrinkable synthetic fiber yarn such as an acrylic fiber yarn as a pile yarn is specified. In addition to the production method according to 3, the double warp knitted fabric used as the material or the single-sided pile knitted fabric after setter cutting is subjected to a steaming heat treatment or a counter-dyeing process including a steaming heat treatment in advance. In the case of the anti-dyeing step, not only can the finished color tone of the blanket be made to a desired good one in the case of the anti-dyeing step, but also the crimping property and bulky property are imparted to the synthetic fiber pile yarn by steaming heat treatment,
During the raising process performed in the next step, the removal of fibers from the pile yarn and the generation of fluff are suppressed, and a favorable raised pile layer can be formed. In addition, since it is manufactured through two heat treatments of a steaming heat treatment and a printing treatment, a blanket having extremely excellent drapability can be manufactured.

Further, the blanket of the present invention according to claim 5 is:
The present invention specifies the configuration of a warp knitted single blanket manufactured by the manufacturing method according to claim 1, and in addition to the feature of light weight based on a single warp knitted blanket, occurrence of hair removal and peeling as described above. It is possible to provide a blanket having a unique design with different patterns and patterns on the front and back surfaces, which are not seen in the conventional New Meyer blanket, while having a small amount of water and excellent durability. Furthermore, the heat retention can be further improved.
