Description

The present invention relates to a curtain suitable for a window of a building that lives with an arboreal pet such as a cat.

The number of cats kept by humans is steadily increasing, and according to the 2013 National Dog and Cat Breeding Survey conducted by the Japan Pet Food Association, the estimated number of cats nationwide has reached 9,743,000. ing. Since this figure does not include outside cats, it is expected that a significant portion of it will be kept indoors.

When keeping cats indoors, most of them are kept in a state where they can move around freely. Cats are arboreal animals and are not good at high altitudes, but rather tend to actively move to high altitudes. For this reason, we often see cats skillfully climbing chests of drawers and walls, and curtains have become a good target, as shown in Fig. 1.

However, it is not uncommon for cats to weigh more than 5 kilograms when they become large species. General curtains are not designed to withstand such loads. Therefore, when the cat repeatedly climbs up and down the curtain, the thread frays or a hole is made. If a hole is made, the light leaks from the hole and the light-shielding property cannot be exhibited, so that the function as a curtain cannot be fully exhibited.

In addition, the curtain is located between the window and the room, and is an important element that constitutes the house from the functional aspect such as blocking the view and heat insulating, but the design element as the interior of the room is also large. The frayed or punctured thread was extremely unattractive and was a problem for cat lovers.

As shown in Patent Document 1, efforts have been made to hang towels indoors as playthings that are more attractive than curtains in order to distract the interest of cats, but both towels and curtains are attractive toys for cats. And because cats are capricious, even if they succeed in removing their attention from the curtain, they can only be a temporary measure.

As a sure measure, it is conceivable to physically separate the cat from the cat, such as installing a fence around the curtain or keeping the cat from entering the room with the cat. However, the provision of fences greatly changes the appearance of the room and causes inconvenience for human traffic. Even if you block the door of a room, cats are so agile that they cannot completely prevent them from taking advantage of human traffic and passing through the door. In a room with curtains, it is possible to put the cat in a cage, but this is a kind of abuse of cats and cannot be adopted by cat lovers.

After all, it's all about disciplining cats. However, cats have a free temperament by nature, and there are many cases where they fail to discipline depending on the breed and personality of the individual cat. Also, too strict discipline narrows the room for the cat to play its role as an animal companion.

Japanese Unexamined Patent Publication No. 2011-097863

Therefore, at present, it is extremely difficult for cat lovers who keep indoors to keep the curtains clean. In order to solve the problem, instead of thinking about various measures to prevent the cat from climbing the curtain, the cat does not deteriorate even if the cat takes any action against the curtain, so to speak, a fail. The safe point of view is important. However, until now, there has been no curtain that has been thoroughly examined from the viewpoint of fail-safe for cat behavior.

The present invention has been made in view of the above background, and an object of the present invention is to provide a curtain that is extremely difficult for a cat to climb, so that damage caused by a cat's claws or the like is not applied to the curtain. It is in.

The present inventor observed the movement of a cat when climbing a curtain, and investigated in what cases a cat could climb the curtain. As a result, it was found that it can be roughly classified into three patterns.

The first pattern is the case of climbing the curtain by putting a nail in the gap between the intersections of the fabrics constituting the curtain, that is, the gap where neither the warp nor the weft exists. be.

More specifically, the cat first screwed the tip of its claw into the gap of the curtain and then inserted the claw deeply to expand the hole to the size of the central part, which is larger in diameter than the tip of the claw. , The claws were made to bite into the curtain to the extent that it could support the weight of the cat.

In this case, a gap (hole) larger than the gap originally possessed by the fabric constituting the curtain is opened, the appearance is deteriorated, and the light-shielding performance is also deteriorated. Furthermore, since it also serves as a good scaffolding for cats to climb the curtain on the next occasion, it will be used repeatedly by cats and the curtain will suffer even greater damage.

The second pattern is a case in which a scaffold is secured by hooking a nail on a thread protruding from the surface side of the fabrics constituting the curtain. In bouldering, which is a competition in which humans climb a slope, the steep slope is climbed by making good use of the uneven parts of the wall surface, which can be said to be the same as this movement.

The curtain is a woven fabric, which is a fabric in which warp and weft are woven. Currently, various weaving methods are known, but the basic plain weave is to pass the warp and weft between the warp and warp. In order to make a cloth, adjacent wefts are woven so that the wefts exposed on the front side and the wefts exposed on the back side of the warp alternate at the same warp location. Therefore, every other weft is lined up on the front side of the fabric.

Therefore, when the front side of the fabric is enlarged, a very small but concave space is created between the warp and weft, and by prying the cat's claw into this space, the tip of the claw can be caught on the warp and weft. can. A large force is applied to the warp and weft that is caught by the claw in the direction of gravity, and it gradually stretches. Along with that, the space gradually expands, making it easier to catch your nails. Eventually, a gap will be created between the warp and weft, which also corresponds to the first pattern, making it easier for cats to climb.

In addition, as the weaving method of the cloth, a weaving method in which the warp and weft straddle a plurality of warps, such as Sugi Aya weaving, is often used, and is often used for curtains from the viewpoint of design. Compared to the case of straddling one warp, the area where the claw can be hooked is wider, and the range in which the weft can move in the vertical direction is larger, so that the gap between the warp and the weft becomes larger more rapidly. It's easier to do and the problem is serious.

The third pattern is when the fabric that makes up the curtain clings to the cat's paws, and the cat attaches the clinging curtain itself to the window glass or wall near the curtain, or the shape of the cat's claws. It is used as a foothold by making it alive and biting into it. In particular, when the thread is unwound and the fiber is spilled, the fiber is easily entangled in the foot, so that the cat can easily use it as a scaffold. It occurs frequently when the fabric is thin and soft.

In this case, as in the case of the first pattern and the second pattern, a hole is formed in the fabric, and a large frictional force is repeatedly applied to the surface of the fabric by a cat's claw or the like, so that the surface of the thread constituting the fabric is fluffed. If the thread breaks, the texture of the surface will eventually change, and it will not be possible to fully demonstrate its function as a curtain.

In addition to the damage to the curtains of each of the first pattern to the third pattern, it cannot be ignored that the contact with the cat's claws damages the thread itself constituting the fabric. That is, when the cat's claws come into contact with the threads on the surface of the fabric, the threads are damaged, the fibers constituting the threads are unwound, and small fibers are spilled from the fabric. In the case of yarn using long fibers, the length of the fibers that fall off becomes long, and the appearance is greatly deteriorated.

From these observation results, when developing a curtain that cats cannot climb, it is necessary to make the density at which the warps and wefts of the fabric intersect above a certain level and eliminate the gap where the cat's claws are screwed. Is. As a second point of view, it is necessary to keep the warp and weft tightly entwined with the warp. From the third viewpoint, it is necessary to give the cloth a certain thickness or more, to give it hardness, and to keep the friction coefficient of the cloth low so that the cloth does not become too soft. As a fourth aspect, it is necessary to minimize the length of fibers spilling from the fabric when the yarn is damaged.

Based on the above viewpoints, in the present invention, a cloth in which warp and weft are woven at a certain density or higher is used by adjusting the weaving method and the density of the yarn. As the yarn, worsted yarn and polyester fused yarn, which are yarns made of short fibers, are used, and after making a fabric, the fused yarn is melted in a high temperature environment and then cooled to maintain the intersection of the warp and weft. It functions as an adhesive. By spreading the melted fused yarn over the entire surface of the woven fabric, the friction coefficient of the woven fabric is lowered, and the effect of imparting a certain hardness to the woven fabric is also aimed at. It also makes it possible to minimize the amount of fibers that spill when the yarn is damaged.

Since the cloth is woven with a certain density or more with respect to the cloth of the present invention, the cat cannot find a gap enough to bite the claws and cannot climb well. Further, since the connection between the warp and the weft is strong, the weft is firmly held by the intersection of the weft and the warp even when the claw is caught on the weft, so that the warp does not stretch. Furthermore, since the fabric itself has a certain degree of hardness, it does not cling to the cat's paws and has a low coefficient of friction, so even if the curtain is attached to the window, it will not fluff. Even if the thread itself is inevitably damaged when it is repeatedly exposed to scratches by the cat's claws, the thread is composed mainly of the staple fibers, so the spillage of the fibers can be minimized and the appearance is good. It doesn't get much worse.

Therefore, even in an environment of living with a cat, the cat cannot climb the curtain of the present invention, and the cat does not hurt the curtain. Since the low coefficient of friction of the material of the curtain is an excellent property, it is possible to provide an excellent curtain to the cat lover.

Hereinafter, embodiments of the present invention will be described with reference to appropriate figures. Generally, the fabric is composed of weaving warp and weft. The exception is non-woven fabric, but the present invention does not cover non-woven fabric.

What is important in realizing the low-friction fabric 1 of the present invention is that it does not give a foothold to the cat. While the inventor observed the cat, it was found that the cat used the scaffolding in three patterns when climbing the curtain.

The first pattern is to put a nail in the gap between the warp and the warp, that is, the gap between the warp and the weft where the yarn does not exist and the gap is formed in the cloth constituting the curtain. This is a case of climbing a curtain using a gap as a foothold. It should be noted that this gap expands as the cat inserts the claw deeply from the tip to the base of the claw, and becomes a large gap, which is the main cause of deteriorating the appearance of the curtain.

The second pattern is a case in which a scaffold is secured by hooking a nail on a thread protruding from the surface side of the fabric constituting the curtain. In portering, which is a competition in which humans climb a slope, the steep slope is climbed by making good use of the uneven parts of the wall surface, which can be said to be the same as this movement.

Various weaving methods are known, but taking the most basic plain weave as an example, adjacent wefts alternate between the wefts exposed on the front side and the wefts exposed on the back side at the same warp. Weave so that it becomes. Therefore, every other weft is lined up on the front side of the fabric. Therefore, there is a very small but concave space between the wefts, and by prying the cat's claws into this space, the tip of the claws can be hooked on the wefts.

Although the weft is held by the left and right intersections that intersect the warp, it is a woven fabric, so there is some play. The warp and weft can move only in this play area, and for cats, the claws can be screwed deeper.

In the fabric on which the nails are caught, the threads constituting the fabric are damaged by the nails, causing fluffing and popping out of the threads, and the appearance is impaired. The cat's claws bite into the tissue, and the weight of the cat and the movement of climbing up and down further expands the space, making it easier to catch the claws. Eventually, a gap will be created between the warp and weft, which also corresponds to the first pattern, making it easier for cats to climb.

As the weaving method of the cloth, a weaving method in which the warp and weft straddle a plurality of warps is often used. Compared to the case of straddling one warp, the area where the claw can be hooked is wider, and the range in which the weft can move in the vertical direction is larger, so that the gap between the warp and the weft becomes larger more rapidly. It's easier to do and the problem is serious. Since cats have strong spatial cognitive ability and muscular strength and may move the curtain in the lateral direction, the above-mentioned second pattern applies not only to warps but also to warps.

In the third pattern, the cloth constituting the curtain clings to the cat's paw, and the curtain itself is attached to the window glass or wall near the curtain to form a scaffold. This is especially noticeable for thin curtains. In particular, when the thread is unwound and the fiber is pulled out, the fiber is easily entangled in the foot, so that the cat can easily use it as a scaffold. It occurs frequently when the fabric is thin and soft.

In this case, as in the case of the first pattern and the second pattern, the fabric has holes, and a large frictional force is repeatedly applied to the threads constituting the fabric by the cat's claws or the like, so that the surface of the fabric is gradually scraped. Eventually, the texture of the surface will change, and it will not be possible to fully demonstrate its function as a curtain.

In order to realize a curtain that cats cannot climb, it is necessary to close all the first to third patterns. Moreover, even if the cat cannot climb the curtain, the area near the floor will be exposed to the stress of the cat's claws on a daily basis. When the contact of the nails to the same place overlaps and the damage is accumulated, the thread itself that constitutes the curtain is unwound at some point. If this happens, the fibers that make up the yarn will be exposed and spill out from the fabric, and the appearance as a curtain will be significantly deteriorated. Therefore, this measure is also necessary.

First, in order to close the first pattern, it is important to reduce the gaps in the fabric, more preferably to eliminate the gaps, and to prevent the cat from inserting the claws. For that purpose, it is important to shorten the distance between the warp and the warp and the weft and the weft that are adjacent to each other, that is, to increase the density of the yarn.

Even if the yarn density is the same, if the yarn is thin, the gap will be large, and if the yarn is thick, the gap will be small, and ultimately it will be zero. By using the cover factor, which is an index that generally expresses such a relationship, the thickness and the yarn density of the yarn can be treated together.

The cover factor is an index showing the degree of the gap between the yarns, that is, how much the thickness of the weaving yarn occupies per unit length of the fabric. A small cover factor means that the gap between threads is wide, and a large cover factor means that the gap between threads is small.

As a result of diligent experiments by the present inventors, it was found that the first pattern can be closed if the fabric has a total cover factor of 1740 or more.

In order to close the second pattern, it is important to keep the warp and weft firmly entwined to reduce play, and as a method for realizing this, it is effective to fuse the warp and weft. Various adhesive resins may be used as the fusion method, but various low melting point resins, particularly low melting point polyesters, have a natural finish and can exhibit necessary and sufficient adhesive strength. After weaving the warp and weft into a cloth, heat it to a temperature at which the low melting point resin melts, fuse the intersection with the low melting point resin, and then cool to solidify the low melting point resin, then the warp and weft will intersect. It is glued and reinforced with.

There are two main ways to use the low melting point resin. The first method is a method in which a fabric is woven with warp and weft, a required amount is applied, and the fabric is heated and cooled. In the second method, a low melting point resin fiber is blended, or a fused mixed yarn using a low melting point resin fiber is used for a warp and / or a weft, and the fused component is melted by heat setting after making a fabric. It is a method of solidifying. A fused mixed yarn is a special yarn in which a low melting point resin fiber is contained in the yarn. Either method may be used, but the second method is superior in terms of production efficiency and the like, and can be said to be a method more suitable for mass production.

As a result of repeated diligent experiments by the present inventor, when the second method is adopted, if the polyester fusion mixture ratio exceeds 2% in the case where the polyester fusion mix yarn is adopted, the warp and weft will be stable at all intersections. It turned out that it is possible to firmly bond the wefts. The fusion blend ratio is the ratio of the weight of the fusion component to the important part of the yarn. When applying the low melting point resin, an amount equivalent to this may be applied.

In order to block the third pattern, it is necessary to reduce the possibility that the fabric will move too freely and cling to the cat's paws. By the way, the curtain can be divided into thick and thin depending on its thickness. Due to the rigidity and weight of the thick curtain itself, no matter what kind of movement the cat makes, a repulsive force is generated and the cover factor is large, so the amount of hardness given to the fabric is compared. It is effective even if it is at least targeted.

The thin curtains move freely due to the softness and lightness caused by their thinness, cling around the cat's paws in conjunction with the cat's behavior, and the claws bite into the clinging curtains to climb as a scaffold. go. As a result of trial and error, the inventor found that in order to prevent this, it is effective to give the cat a certain degree of hardness to make the surface of the curtain slippery, which causes movement to escape from the movement of the cat's limbs. found.

There are various known methods for hardening the curtain and keeping the coefficient of friction of the curtain surface low, but the most effective method is to use more of the low melting point resin used to prevent the second pattern. .. In order to bond the warp and weft at the intersection, a fusion blend ratio of about 2% is necessary and sufficient, but if the fusion blend ratio is further increased, the low melting point resin is also applied to regions other than the intersection when the low melting point resin is heated. Spreads and covers the surface of the fabric.

When the low melting point resin is resolidified, it becomes a lumpy form with more restricted movement than the main body of the fabric, which is a woven fabric made of warp and weft. By covering many areas of the fabric with the lump made of the low melting point resin, the movement of the fabric as a whole is restricted, that is, the softness is lost and the fabric can be made hard. This hardness increases as the thickness of the mass increases. In order to increase the area of the mass and increase the hardness, the fusion mixture ratio may be further increased.

However, the higher the fusion mixture ratio, the better. This is because a certain degree of softness is required to maintain the natural movement of a thin curtain. As a result of repeated diligent experiments by the inventor, when the polyester fusion yarn is used, the fusion mixture ratio can be secured to the extent that it does not cling to the cat's paws when it exceeds 8%, and it is acceptable if it is less than 10%. It turned out to fit in as hard as possible. The same applies when applying polyester.

The resin mass generally has a lower coefficient of friction than a fabric woven with warp and weft. Therefore, as the fusion mixture ratio increases, the region covered with the resin lumps also increases, and the region having a lower coefficient of friction as the entire fabric increases. Therefore, if a method of increasing the fusion mixture ratio is adopted as a method of imparting hardness in order to prevent the third pattern, it is possible to achieve a reduction in the friction coefficient of the fabric at the same time.

As a method of increasing the hardness and lowering the coefficient of friction, the 100% polyester fabric has a stronger function of the low melting point resin than the fabric with mixed weave, and the coefficient of friction is lower because the hardness differs even with the same mixing ratio. As the yarn, a yarn made of polyester is the most suitable.

Although the measures for preventing the first pattern to the third pattern have been described above, all the patterns must be prevented in order to realize a curtain in which the cat does not climb. Therefore, the total cover factor is 1740 or more as the first pattern countermeasure, and the yarn using the low melting point resin fiber is adopted as the second pattern countermeasure, and the fusion mixture ratio of the low melting point resin, for example, polyester is 2% or more. As a third pattern measure, it is not necessary to take more measures than the second pattern measure for thick curtains, but for thin curtains, the polyester fusion mixing ratio when threads using low melting point resin fibers are used. Is to be 8% or more. However, the fusion mixture ratio must be 10% or less in order to avoid becoming too hard.

If the fabric meets these three conditions, the cat will not be able to climb, but it will avoid contact with the cat's claws on a daily basis near the floor and accumulation of damage to the threads. Finally, the thread itself collapses, the thread that makes up the fabric breaks, and the thread is pulled out, giving the appearance of spilling from the fabric, which is unattractive. Since this cannot be avoided, even if it spills, the deterioration of the appearance can be minimized by adopting a thread composed of short fibers so that the length is minimized. .. Therefore, it is effective to weave the fabric mainly using threads composed of short fibers and more preferably using only threads composed of short fibers.

By the way, in the process of manufacturing a woven fabric, a dyeing process for processing the woven fabric is required. The temperature needs to be adjusted.

Whether or not the low-friction fabric 1 manufactured in this way functions as a curtain that the cat cannot climb can be reliably determined by actually climbing the cat. The content is that each cat is guided to the vicinity of the curtain by flickering the food, and when the food is further moved to a high place near the curtain, the cat tries to climb the curtain in order to obtain the food. Do this 10 times for one cat. The above test was conducted on a total of 10 cats of various breeds and body shapes shown in Fig. 3, and all cats passed the case where they could not climb the curtain even once, and cats that could cling to them even if they could not climb. If there was one or more cats, it was judged as a semi-pass, and if there was even one cat that could climb, it was rejected.

The above-mentioned method using an actual cat is a method for directly determining the effect of the present invention, but as a more objective method, a snag test was also performed. Snag is a phenomenon in which fibers and threads protrude from the surface of the fabric due to contact with the outside and cause dragging. As shown in Fig. 2, the snag test is a process in which a cloth used as a test sample is wound around a cylinder, a golf ball-sized sphere with a nail-like spike is hung from above the cylinder, and the cylinder is rotated. This is a test in which a sphere randomly bounces and a spike comes into contact with a cloth to generate a snag, and after a certain number of times the cylinder is operated, the grade is determined according to how much the snag is generated.

If the tip of the spike bites into the fabric even a little, it gives an irreversible change to the bite tip, and if the change is remarkable, it damages the cloth and generates a snag. Therefore, it can be said that a woven fabric that does not generate snags, that is, a fabric that is highly evaluated in the snag test, is a fabric in which spikes do not easily bite. When replaced with a cat, it is a fabric that makes it difficult for cat's claws to bite into it.

Snag tests are performed in each of the vertical and horizontal directions. The vertical snag test measures the occurrence of scratches on the warp and weft, that is, scratches on the warp. The lateral snag test measures the occurrence of scratches in the warp direction, that is, scratches on the weft. The results of the lateral snag test are important because suppressing the cat from climbing from bottom to top is synonymous with suppressing scratching in the warp direction.

As a result of the present inventor comparing and examining the results of the experiment of actually climbing a cat and the snag test, the snag test (A) conducted by the Japan Textile Product Quality Technology Center and the Kaken Test Center. Method: It was found that a fabric obtained with a grade of 4.5 or higher in the ICI type mace tester method) is equivalent to a fabric that does not correspond to the first pattern and the second pattern in which a cat climbs. ..

Therefore, if the result of the lateral snag test is grade 4.5 or higher, it is possible to provide a curtain that the cat cannot climb by the first and second patterns. It should be noted that cats are capricious creatures and sometimes move in the horizontal direction, so it is more reliable if the vertical grade is 4.5 grade or higher.

The low-friction fabric 1 that is difficult for cats to climb has been described above. As an example thereof, four types of thick fabrics and one type of thin fabrics are manufactured, and two types of thin fabrics are manufactured as comparative examples. A snag test and a cat test were conducted.

In Examples 1 to 5, Thick Plain Weave 1, Thick Plain Weave 2, Thick Plain Weave 3, Thick Plain Weave 4, Thin Boil, Thin Boil Comparative Example 1, and Thin Boil Comparative Example 2, a plurality of wefts are described. In the example described above, the plurality of yarns are used in the same ratio to form a warp and weft. However, for the thick plain weave 1, the cotton polyfused mix yarn 20 /-is 50%, the cotton polymix hot cloth 24 /-is 25%, and the policelab 10 /-is 25%.

The results of the cat experiment were acceptable in all examples. The snag test was graded 4.5 or higher both vertically and horizontally, and especially the thin boil was grade 5. This is because it is a hard fabric because it does not use any cotton, and because the fusion mixing ratio is as high as 9.40%, the entire surface is covered with a resin film, which makes it extremely resistant to spikes. It is thought that this is because it is a tough fabric.

On the other hand, in Comparative Example 1 of thin boil, a grade of 4.5 was obtained in the snag test, but one cat succeeded in clinging to it even if it did not climb the curtain, and was a semi-pass. It is probable that the cloth was easily clinging to the cat's paws due to the thin material, and it was not possible to give sufficient hardness at the fusion mixing ratio of 7.7%. It is probable that the fact that 41.63% of cotton was contained also had a high coefficient of friction and had an adverse effect.

In Comparative Example 2 of thin boil, a grade of 4.5 was obtained in the snag test, but the cat test was rejected because multiple cats succeeded in climbing the curtain. Since the fusion blend ratio was as low as 4.45%, it is probable that the fabric could not be sufficiently firm and was soft enough to cling to the cat's paws. From the experimental results of Comparative Examples 1 and 2, the result of the cat experiment was worse in Comparative Example 2 even though the ratio of cotton was smaller, which was the fusion ratio of polyester rather than the coefficient of friction of the yarn. It can be seen that it is important to increase.

The results of Examples 1 to 5 and Comparative Examples 1 and 2 are analyzed as follows. First, in order to prevent the first pattern, the cover factor may be 1740 or more. In order to prevent the second pattern, the fusion mixture ratio may exceed 2.2%, and when data of other trial and error performed is taken into consideration, it may exceed 2%. In order to prevent the third pattern, the thick material may exceed 2% as in the second pattern. For thin land, it is possible to cling to it even if it cannot be climbed if the fusion splicing ratio is 7.7%, and it is not possible to climb if it is 9.4%. Taking into account the data of other trial and error, it has been found that the third pattern can be prevented if it exceeds 8%.
