Description

  The present invention relates to a braille reading aid fabric and a braille reading aid having a function of assisting the reading of braille characters.

  As a method for producing a Braille print, a method has been practiced in which each point constituting a Braille is pushed out from the back of the paper as a reverse character by hand. In recent years, as a method for more efficiently producing braille printed matter, after printing braille characters by screen printing or the like using foamable ink, the foamable ink is heated and foamed to form braille characters, After printing Braille characters, called Barco printing method, spray the thermoplastic resin powder in an undried state after ink, remove the thermoplastic resin powder that does not adhere, and then melt and solidify the thermoplastic resin powder by heating. A method of forming characters has been performed.

  However, both the method using foaming ink and the Barco printing method are subject to heat treatment, so there are restrictions on the materials for printing braille characters, and the use of materials such as films, plastics, and metals that do not penetrate normal inks. There was also a restriction that it was not applicable.

  Therefore, recently, as a printing method that replaces these methods, a method of using a UV curable resin ink to print thickly in the shape of a Braille convex portion and then irradiating with UV rays and curing has been used. In the case of the ultraviolet curable resin ink, since it is cured in a very short time, it can be applied to materials such as films and plastics. Also, by using colorless and transparent UV curable resin ink, braille characters can be formed without losing characters and patterns on general printed matter, so that sighted people and visually impaired people can share information on the same printed matter. It also has the advantage of being able to. For this reason, it has been adopted rapidly for pharmaceutical packages, restaurant menus, business cards, handrails on stairs, and train car guidance.

  However, in Braille characters using UV-curing resin ink (hereinafter referred to as UV Braille), the UV Braille printing method itself applies the existing printing technology, so the size of the UV Braille varies depending on the printing manufacturer. There is a problem that identification is difficult. In addition, since Braille is read while sliding a finger, there is a problem that it is difficult to read when printed on a material with poor finger slip.

  As a method for solving such problems in UV Braille, the present inventors examined the influence of Braille patterns and printing materials on the ease of identification of UV Braille (for example, see Non-Patent Documents 1 and 2), and UV. Nylon cloth or polyester nonwoven fabric finger sack has been proposed as an auxiliary tool for improving the readability of Braille (for example, see Non-Patent Documents 3 to 5).

  Further, in Patent Document 1, braille having fibers with an average fiber diameter of 0.01 to 10 μm, a thickness of 10 to 50 μm, an average density of 30 to 90%, and a surface dynamic friction coefficient of 0.25 or less. A fine fiber assembly for palpation assistance and a finger sack made from the fine fiber assembly are disclosed. Specifically, the example shows an example in which a braided non-woven fabric obtained by electrospinning and made of nylon having an average fiber diameter of 185 nm is heat-bonded with a calender roll and is touched on the index finger. Yes.

  However, in the case of a finger sack-shaped braille reading aid, when a visually handicapped person tries to use it constantly, it is difficult to fit it when it falls out of the finger during use or when it tries to fit into the finger quickly. It has become clear that there are problems such as, and problems such as being too small and easy to lose.

  The present invention has a function of improving the identification of Braille characters when reading Braille characters, is easy to fit, does not come off the finger during use, and is easy to use with little risk of loss during storage. An object is to provide a reading aid fabric and a Braille tactile reading aid.

  According to the study by the present inventors, the reading of Braille is performed by detecting the unevenness of the Braille with the fingertip, so if the unevenness of the Braille can be detected more accurately, the reading speed of the Braille characters will be improved. The frequency of mistakes also decreases, and the accuracy when sensing irregularities in Braille is improved by improving the followability of the irregularities in Braille, so covering the fingertip with a woven or non-woven fabric will improve the accuracy of Braille irregularities. It has been found that it can improve following ability.

  As a result of intensive studies to solve such problems, the present inventors have found that a woven fabric having a small bending stiffness (B) by the KES method, a small surface average friction coefficient, and a small average deviation is rough. Therefore, it is suitable for use as a braille reading aid, and at least the fingertip portion for identifying braille is formed of the above-mentioned fabric, and the glove as a whole. As a result, the present inventors have found that it becomes a Braille reading aid that exhibits a Braille character identification function and excellent usability.

That is, the present invention is a woven fabric using fibers having a single fiber fineness of 0.01 to 1.5 dtex, and the average value in the warp direction and the transverse direction of the bending stiffness (B) of the fabric by the KES method is 0. 0.1 (gf · cm ² / cm) or less, the average value of the average friction coefficient (MIU) of the fabric surface by the KES method is 0.3 or less, and the average deviation of the friction coefficient (MMD) The average value of the vertical direction and the horizontal direction is 0.02 or less. In addition, the present invention provides a braille reading aid glove characterized in that the above-mentioned braille reading aid fabric is disposed at least on the fingertip portion that contacts the braille unevenness. It is preferable that the glove for assisting Braille reading uses a woven fabric or a knitted fabric in which stretch recovery fibers are partially used on the back side of the hand and / or finger.

  According to the present invention, high discriminability when reading Braille, that is, improving reading speed and reducing the frequency of misreading, is easy to put on, is difficult to remove after wearing, and is taken out from a storage place such as a bag or pocket. A braille reading aid that is easy and less likely to be lost is provided.

It is explanatory drawing which showed the relationship between the bending moment and curvature in the measurement of a bending rigidity value.

In the braille reading aid woven fabric of the present invention, the average value of the bending direction (B) by the KES method in the vertical direction and the horizontal direction is 0.1 (gf · cm ² / cm) or less, preferably 0.05. (Gf · cm ² / cm) or less. In the present invention, the warp direction is the length direction of the fabric, and the weft direction is the width direction of the fabric (hereinafter the same). By setting it to 0.1 or less, there is no hardness and stiff feeling, the followability of Braille dots to the dot shape is improved, and the decoding speed (number of decoded characters per minute) can be increased.

The bending stiffness (B) by the KES method is the bending stiffness per 1 cm width of the fabric, and is measured using a KES-FB2 testing machine in an environment of 20 ° C. × 65% RH. The fabric for measurement is moved so that the bending curvature M of the fabric is 0 to +2.5 to 0 to −2.5 to 0, and the bending moment M (gf · cm / cm) and the curvature as shown in FIG. A curve showing the relationship with K (cm ⁻¹ ) is obtained, and can be determined from the slope of this curve. Measurements were taken at two points between K = 0.5 and 1.5, and between K = -0.5 and -1.5, and the surface bending (bending with the surface facing outward) and the back side, respectively. The average value of the gradient of bending (bending with the back side facing outward) is used.
Further, the hysteresis (2HB) can be obtained from the difference in bending moment between the curve deformation process and the recovery process. The hysteresis (2HB) is preferably 0.02 or less.

  In the Braille touch assisting woven fabric of the present invention, the average value of the average friction coefficient (MIU) of the fabric surface by the KES method is 0.3 or less, preferably 0.1 to 0.3. It is. By setting it to 0.3 or less, since there is no rough feeling and good slipperiness can be obtained, it becomes easy to decipher Braille and the detachability of the Braille reading aid (gloves) is improved. Moreover, by setting it as 0.1 or more, it becomes easy to process into a Braille reading aid with an appropriate resistance, and the wear feeling is good.

  The average friction coefficient (MIU) of the fabric surface by the KES method is measured under an environment of 20 ° C. × 65% RH using a KES-FB4 testing machine. The contact surface is crimped to the fabric with a force of 50 gf by placing 10 pieces of piano wire of 0.5 mmφ on a fabric applied with a tension of 20 gf / cm and winding them on a surface of 5 × 5 mm, and the contact surface is crimped to the fabric by 0.1 cm / sec. Measure the frictional resistance applied to the contact when it is horizontally moved 2 cm at a constant speed, and divide the average frictional resistance obtained from the relationship between the frictional resistance and the distance traveled by the sample by the weight of the contact. Can be obtained. The average deviation of the friction coefficient is MMD.

  The fabric for braille reading of the present invention has a mean deviation (MMD) of the friction coefficient of the fabric by the KES method of 0.02 or less, preferably 0.015 or less. If it is 0.02 or less, since MIU is substantially constant, better slipperiness can be obtained, and the braille decoding speed can be further increased.

  The fabric for assisting Braille reading according to the present invention is not limited to the value (μm) of the mean deviation (SMD) of the surface roughness of the fabric by the KES method. 4.0 (μm) or less is preferable because it affects the tactile sensation during reading and may increase the misreading rate and decrease the reading speed. The average deviation (SMD) of the fabric surface roughness by the KES method is measured under an environment of 20 ° C. × 65% RH using a KES-FB4 testing machine. A contact obtained by bending a 0.5 mmφ piano wire into a width of 5 mm is pressed against a sample at 10 gf on a fabric applied with a tension of 20 gf / cm. This contact is pressed by a spring, and the constant of the spring is 25 gf. It is an average deviation of the surface roughness of the fabric when the pressed contact is moved 2 cm horizontally at a constant speed of 0.1 cm / sec.

  Examples of the fibers constituting the woven fabric include natural fibers such as silk fibers, polyamide (nylon) fibers, polyester fibers, and synthetic fibers such as composite fibers of nylon and polyester. The ratio of nylon to polyester in the composite fibers is as follows. It can be arbitrary. Moreover, the mixed fabric of 2 or more types of fibers may be sufficient.

  Fabrics using silk fibers are excellent in touch and feel of Braille, and can withstand long-term use because they are hygroscopic and dry quickly after water absorption. Fabrics using synthetic fibers are versatile because they can be processed into gloves by sewing or hot pressing, and the above synthetic fibers have a low coefficient of dynamic friction and high tensile strength, so that they become durable and durable fabrics.

  In the textile for assisting Braille reading according to the present invention, it is preferable to use a fiber having a single fiber fineness of 0.01 to 1.5 dtex as the fiber. When the single fiber fineness is 0.01 dtex or more, the occurrence of fluff due to friction is less likely to occur, so there is less risk of affecting the reading of Braille, and when it is 1.5 dtex or less, a smooth fabric surface Can be obtained. In the case of a synthetic fiber, a more preferable single fiber fineness is 0.05 to 0.7 dtex.

  The total fineness when using the above-mentioned fibers as warp or weft is preferably 10 to 50 dtex, and by setting the total fineness to 10 dtex or more, it is possible to obtain a tear strength that can be practically used even in the case of a glove. it can. In addition, the tactile sensation is not affected by setting the total fineness to 50 dtex or less.

  The fabric used in the present invention can be produced by a known method for producing a fabric made of natural fibers or ultrafine fibers. In the case of natural fibers, for example, after producing a woven fabric using silk fibers, the hot-washed components (such as sericin) are removed from the silk fibers by washing with hot water, and then the woven fabric has an improved texture. Can be produced. In the case of synthetic fibers, for example, after producing a woven fabric using sea-island type fibers or split-type fibers, in the former case, the sea components are dissolved and removed with a chemical, and in the latter case, the chemical or physical The two components can be peeled off by treatment to produce a woven fabric composed of ultrafine fibers.

  Examples of the weaving (weaving method) of the woven fabric include plain weave, twill weave, leash weave, satin weave, triaxial weave, horizontal stripe weave, and oblique weave, and are not particularly limited. The satin weave and plain weave are preferable from the viewpoint of reducing the dynamic friction coefficient.

  The types of fibers forming the warp and weft of the fabric may be the same or different. For example, nylon fibers may be used for both the warp and the weft, and polyester fibers may be used for both the warp and the weft. Alternatively, the warp yarn may be nylon fiber, the weft yarn may be polyester fiber, the warp yarn may be polyester fiber, and the weft yarn may be nylon fiber. Furthermore, the warp yarn may be a composite yarn of nylon fiber and polyester fiber, and the weft yarn may be polyester fiber or nylon fiber.

  The cross-sectional shape of the fiber used in the present invention may be a round cross-section, a triangular cross-section, a flat cross-section or other known irregular cross-sections, but from the viewpoint of tactile sensation, a triangular cross-section irregular cross-section fibers are preferably used.

In the present invention, the braille reading aid uses at least a fingertip portion that contacts the unevenness of the Braille, if a fabric having the above characteristics is used, or a fingertip portion that does not contact the unevenness of the Braille, or a finger portion other than the fingertip, Even if another fabric is used for the palm or back of the hand, it does not affect the followability of the braille to the uneven shape, and hence the accuracy with which the fingertip senses the unevenness. Therefore, the Braille touch assisting tool only needs to have the Braille touch assisting fabric of the present invention disposed at least on the fingertip portion that contacts the unevenness of the Braille. Here, the “fingertip portion” refers to a portion ahead of the first joint of each finger of the hand.
As such Braille reading aids, the fabric of the present invention is cut into a handkerchief size, and the ends are processed as necessary, or the fabric of the present invention is processed into a finger sack or glove. And so on. Above all, the shape of the glove makes it easy to wear, hard to come off after wearing, no loss during storage, and can improve convenience in use.

  The glove as a braille reading aid of the present invention is not particularly limited as long as the fabric having the above characteristics is disposed at least at the fingertip portion. For example, a fabric having the above characteristics may be disposed only on the palm side of the fingertip that touches the unevenness of Braille, or a fabric having the above characteristics may be disposed on the entire circumference of the fingertip portion. Further, a woven fabric having the above characteristics may be disposed not only on the fingertip portion but also on the entire finger, or a woven fabric having the above characteristics may be disposed on the entire palm side.

  Moreover, in the glove, a material for forming a portion other than the woven fabric having the above characteristics is not particularly limited, and a nonwoven fabric, a woven fabric, a knitted fabric or the like can be used. In terms of obtaining inexpensive and disposable gloves, nonwoven fabric is preferred. In particular, a nonwoven fabric made of thermoplastic fibers is preferably used because it is easily thermoformed. Moreover, since the glove itself can be made lightweight and simple by using a non-woven fabric, it is easy to carry and the convenience is further improved.

However, even if a touch-reading fabric is used, it is easy to misread in a sagging or wrinkled state, and the fabric is in contact with the finger and tension is applied to the fabric portion in order to prevent it from being caught quickly. The state is preferred. Therefore, the fabric used for the back side of the hand is a woven or knitted fabric made of fibers partially using fibers having high stretch recovery properties such as rubber or spandex on the back side of the hand and / or finger (opposite side of the palm side). Gloves that are most preferred.
Alternatively, the shape of the glove may be a mittens type (a glove that covers four fingers excluding the thumb), and after the glove is worn, a sponge is inserted into the back of the hand to apply tension to the fabric that contacts the braille. .

The glove for assisting Braille reading according to the present invention includes, for example, a woven fabric having at least the above-mentioned characteristics that forms the fingertip portion and a part of the glove that is formed of a non-woven fabric other than the portion formed of the woven fabric. It can be easily manufactured by wearing or sewing.
For example, a glove made of a woven fabric having the above characteristics on one side is obtained by cutting a woven fabric having the above characteristics into a palm shape, and then heat-sealing or stitching the non-woven fabric also cut into a palm shape. Can be manufactured.
Alternatively, a fabric having the above characteristics is cut into a fingertip shape, and this is placed on the corresponding fingertip portion of the nonwoven fabric cut into a palm shape without the fingertip portion and heat-sealed. After forming the palm-shaped non-woven fabric, the glove having the braided-texture assisting fabric of the present invention disposed only on the fingertip portion by overlapping the non-woven fabric cut into a palm shape and heat-sealing or stitching Can be manufactured.
Alternatively, the braille reading aid woven fabric of the present invention is cut into a fingertip shape, and this is placed on the corresponding fingertip portion of the nonwoven fabric cut into a palm shape without the fingertip portion, and the fingertip portion is woven. After creating a palm-shaped nonwoven fabric, two sheets of the nonwoven fabric are overlapped and heat-sealed or stitched, so that the braille reading aid fabric of the present invention is spread over the entire circumference of the fingertip portion. Arranged gloves can be manufactured.

  In addition, for example, the glove one side obtained by cutting the woven fabric having the above characteristics into a palm shape, or the corresponding fingertip portion of a nonwoven fabric obtained by cutting the woven fabric having the above characteristics into a fingertip shape into a palm shape without a fingertip portion Highly stretchable, such as rubber or spandex, on one side of the palm-shaped glove with fingertips made of woven fabric and heat-sealed on the back side of the hand and / or finger (opposite side of the palm side) It is possible to manufacture a glove in which the braille reading aid woven fabric of the present invention is disposed only on the fingertip portion by superimposing a fabric or knitted fabric made of a fiber using a portion of the fiber, heat sealing or stitching. it can. However, the above glove manufacturing example is an example and can be manufactured by other methods.

  In addition, in the case of a glove in which the braille touch assisting fabric of the present invention is arranged only at the fingertip portion, it is not necessary to arrange the fabric at every fingertip. For example, the cloth may be arranged on the three fingers of the index finger, middle finger, and ring finger that are usually used for reading Braille characters, and only the index finger that is most commonly used for reading Braille characters. It is good also as a shape which has arranged textiles.

  Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to these examples.

A 20cm x 20cm sample passed through the thread is placed on a smooth metal surface, uniaxial tension of 20gf / cm is applied, and a 0.5mm piano wire is folded to a width of 5mm. Then, the average deviation of the surface roughness when the sample was moved horizontally at a constant speed of 0.1 cm / sec was determined. By the above method, the warp direction of the fabric was measured and the average value was obtained.

(Reference example)
A polyester nonwoven fabric having a basis weight of 12 g / m ² was prepared as a comparative standard.
A glove produced by placing this nonwoven fabric on the index finger had a reading speed of 47 (characters / min) and a misreading rate of 1% as evaluated by Test Method A. When gloves were not worn, the reading speed was 30 (characters / minute) and the misreading rate was 9%. A clear significant difference was observed depending on whether or not the nonwoven fabric was used.

Example 1
A satin woven fabric with 57 g / m ² basis weight is prepared with warp yarn made of ultra-fine composite fiber (polyester / nylon = 83/17) of irregular cross-section polyester and irregular cross-section nylon, weft yarn made of sea-island type polyester ultra-fine fiber did. This fabric had a warp density of 233 (lines / inch), a weft density of 145 (lines / inch), a warp fineness of 34 (dtex), and a weft fineness of 29 (dtex). The single fiber fineness after the dividing line of the ultrafine composite fiber is 0.6 (dtex) for nylon and 0.16 (dtex) for polyester, and the single fiber fineness for Umijima polyester ultrafine fiber is 0.05 (dtex). there were.

(Comparative Example 1)
An oblique fabric with a basis weight of 60 g / m ² was prepared, in which the warp and the weft were made of sea-island polyester ultrafine fibers. This fabric had a warp density of 275 (lines / inch), a weft density of 152 (lines / inch), a warp fineness of 30 (dtex), and a weft fineness of 32 (dtex). The single fiber fineness after sea removal was 0.05 (dtex).

(Comparative Example 2)
A plain woven silk fabric having a basis weight of 16 g / m ² made of silk fibers having a single fiber fineness of about 1.4 (dtex) was prepared. This fabric had a warp density of 126 (lines / inch), a weft density of 88 (lines / inch), a warp fineness of 15 (dtex), and a weft fineness of 16 (dtex).

(Example 2)
The silk fabric prepared in Comparative Example 2 was dipped in hot water at 90 to 95 ° C. containing a softening agent for about 10 minutes, then taken out from the hot water, boiled with steam at about 120 ° C., and contracted and wrinkled. A silk fabric having a basis weight of 16 g / m ² was prepared by extending the width and the like.

  For the fabrics prepared in the reference examples, Examples 1 and 2 and Comparative Examples 1 and 2, the bending properties by the KES-FB2 testing machine method, the fabric surface characteristics by the KES-FB4 testing machine, and the textile for assisting Braille reading The results of evaluating the suitability of are shown in Table 1.

From the results of Table 1, the bending stiffness (B) is 0.1 (g.cm ² / cm) or less, the surface friction coefficient (MIU) is 0.3 or less, and the average deviation of the surface friction coefficient ( The woven fabric having an MMD) of 0.02 or less has obtained good results in the evaluation of suitability as a woven fabric for assisting Braille reading. Since there is no rough feeling compared with the conventional nonwoven fabric, tactile evaluation is good.

  On the other hand, when the surface friction coefficient (MIU) exceeds 0.3 (Comparative Example 1) and the average deviation (MMD) of the surface friction coefficient exceeds 0.02 (Comparative Example 2), both of these examples The evaluation is inferior compared to the fabrics.

(Example 3)
The fabric prepared in Example 1 was cut into a size of 25 mm × 35 mm.
After two non-woven fabrics made of polyester long fibers are stacked and cut into a palm shape, the index finger part of one non-woven fabric is cut and removed at a location 30 mm from the tip, and then the previously cut fabric is placed in the cutting section. (The overlapping part is 5 mm) and heat-sealed with a heat sealer. Next, a non-woven fabric in the shape of a palm with a woven fabric bonded to the tip of the index finger was overlapped with another non-woven fabric cut into a palm shape, and heat-sealed with a heat sealer to produce a glove. . When this glove was evaluated by Test Method B, the wearability was good and the tactile evaluation was ◎.

  The braille touch assist fabric of the present invention and the glove in which it is disposed at least at the fingertip portion can improve the reading speed of Braille and decrease the misreading rate by using it. Because it is easy to wear at the time, difficult to remove after wearing, and less likely to be lost during storage, it is useful as an aid to support participation of visually impaired people in social activities.
