Description

  The present invention relates to a portable shoe cleaner that can easily wipe off dirt on shoes and the like.

  Traditionally, to clean leather products such as shoes and bags, use a cloth or brush to wipe off the dirt on the surface of shoes or bags, and then apply a special chemical to polish them. It is common. Recently, we carry a sheet-like disposable cleaner made of paper or non-woven fabric, and when the shoe or bag gets dirty even when away from home, we can easily wipe off the dirt with the disposable cleaner and improve the appearance. I often do it.

However, no matter how disposable it is, simple sheet-shaped cleaners are not comfortable to use. Proposed. For example, the back side of a cloth suitable for shoe polishing is bonded with a sponge and cut into an appropriate size (see Patent Document 1), or a shoe shoe is provided on one side of a flat shoe polishing body, and the other side Disposable simple shoe polish (see Patent Document 2) provided with an insertion hole for inserting a finger at one end of the shoe.

  These are certainly easier to use than simple sheet-like cleaners, but they are not sufficient in terms of wiping and polishing performance against dirt, have better performance, and are convenient to carry. Things are strongly desired.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a portable shoe cleaner that is convenient to carry and has excellent wiping performance and polishing performance.

In order to achieve the above object, the present invention provides a synthetic resin sheet laminated and integrated on the back surface of a wiping fabric via an elastic layer made of an elastic material, and a finger is placed on the back surface made of the synthetic resin sheet. A portable shoe cleaner provided with an insertion portion for insertion, wherein the wiping fabric is composed of a front yarn and a back yarn having a total fineness of 30 to 150 dtex, a course number of 40 to 90 / 2.54 cm, The surface of a tricot knitted fabric knitted with a knitting density of 40 to 100 / 2.54 cm of wales is raised and the front yarn has a segment fineness of 0.3 dtex or less and extends in the longitudinal direction of itself. portable shoe cleaner, wherein the ultrafine fibers multifilament comprising a combination of segments having a part is found using As one of the subject matter.

The present invention, among them, in particular, the upper Quito Rikotto knitted fabric, n / 1 satin (n is 3 or more) a portable shoe cleaner is of the second aspect.

And among these, in particular, the third aspect is a portable shoe cleaner in which a polishing agent is contained on at least the surface of the wiping cloth, and the polishing agent is a silicone-based one. A portable shoe cleaner that is an oil agent is a fourth aspect .

Furthermore, the present invention is such that, in particular, the portable shoe cleaner is stored in a storage bag made of a synthetic resin sheet that can cover the entire surface of the wiping fabric. Is the fifth gist.

That is, the portable shoe cleaner according to the present invention is a special ultrafine fiber multi-fiber which is a combination of a segment having an edge portion extending in the longitudinal direction as a front yarn of a wiping fabric made of a tricot knitted fabric having a special configuration. because the filaments are found using, wipe the surface of the shoe or the like in this aspect, thereby making it possible to wipe off dirt effectively at the edge portion of the segment. The dirt is retained in the gap between the filaments, but can be easily removed by hand-washing or washing with water, so that it can be used over and over again. It is economical, not wasted.

  Moreover, since each segment is a very thin fiber having a fineness of 0.3 dtex or less, the total surface area of the entire multifilament is large, coupled with the elasticity of the elastic layer provided on the back side, Excellent polishing performance can be achieved on uneven shoe surfaces. And by inserting a finger into the insertion part provided on the back side of the synthetic resin sheet, further on the back side of the elastic layer, the dirt can be easily wiped and polished, which is easy to use.

Then, in the present invention, in particular, the supernatant拭用fabric 帛is, because as a front yarn is obtained by raising the knitted surface of the tricot knitted fabric using the above ultrafine fiber multifilament, is better Kiyoshi拭性In addition to being obtained, it becomes a durable and luxurious portable shoe cleaner.

  In the present invention, in particular, a portable shoe cleaner in which a polishing agent is contained on at least the surface of the wiping cloth is not only polished but also has an excellent polishing effect.

  Among the present inventions, particularly those using a silicone oil as the above-mentioned polishing agent can obtain a more excellent polishing effect.

  Further, in the present invention, in particular, the portable shoe cleaner is to be stored in a storage bag made of a synthetic resin sheet that can cover the entire surface of the wiping fabric. Even if the surface of the wiping fabric is very dirty, if it is stored in the storage bag, it will not stain the bag or the pocket of clothes, so it can be carried with peace of mind.

  Next, an embodiment of the present invention will be described. However, the present invention is not limited to this embodiment.

  FIG. 1 is a schematic longitudinal sectional view showing an embodiment of a portable shoe cleaner according to the present invention. That is, this portable shoe cleaner has a structure in which a brushed wiping cloth 1, an elastic layer 2 made of an elastic material, and a synthetic resin sheet 3 are laminated and integrated. And the pocket 4 for inserting a finger is further provided in the back surface which consists of the said synthetic resin sheet 3 (refer FIG. 5). The pocket 4 is also made of the same material as the synthetic resin sheet 3.

As the wiping fabric 1, a tricot knitted fabric is used, and it is preferable to have a certain degree of elasticity so as to flexibly follow the unevenness of the shoe surface in combination with the elastic layer 2 on the back side. Specifically, it is preferable that the woven or knitted fabric has an elongation rate of 4% or more, more preferably 7 to 40% according to JIS L109684.14.1 elongation rate B method (constant load method).

  The surface of the wiping fabric 1 has a structure in which ultrafine fiber multifilaments having segments having a segment fineness of 0.3 dtex or less and having an edge portion extending in the longitudinal direction are arranged. There must be. That is, by using the above-mentioned special ultrafine fiber multifilament on the surface of the wiping cloth 1, it is possible to obtain excellent wiping performance and polishing performance that cannot be obtained with conventional ones.

  The above-mentioned “edge portion extending in the longitudinal direction” means that the outline of the cross section of the fiber is not a gentle arc, but a bent corner, and the protrusion formed by the corner is formed on the fiber surface. A portion extending along the longitudinal direction. And although the angle of the said corner | angular part may be an obtuse angle, the direction of an acute angle exhibits the more superior wiping performance. However, in the outline line of the fiber cross section, the two sides constituting the corner portion do not necessarily have to be straight lines, and may have an arc shape.

In the supernatant拭用fabric 1 of the surface, in arranging such a special ultrafine fiber multifilament, the tricot knitted fabric constituting the supernatant拭用fabric 1, on at least the surface side, the ultrafine fiber multifilaments It is preferable to use the yarn as shown.

  The ultrafine fiber multifilament is usually obtained by splitting a composite fiber in which two or more kinds of components are bonded to each other in a single fiber while forming a plurality of segments. As a suitable example in which segments having edge portions extending in the direction are combined, for example, a fiber having a cross section as shown in FIG. 2 can be cited. In this figure, “edge portion extending in the longitudinal direction” is indicated by P.

  This cross section has a structure in which a radial type segment 10 and a fan-shaped segment 11 that complements the radial type segment 10 are combined. The fineness (segment fineness) of these segments 10 and 11 is set to be 0.3 dtex or less, and the total surface area of the fibers in the ultrafine fiber multifilament is very large, so that the dirt can be wiped off efficiently. Can do. And since each segment 10 and 11 has many edge portions along the longitudinal direction (the portion indicated by P in FIG. 2 and the same shape portion is omitted), the dirt is scraped off from the shoe surface. It can be removed and exhibits excellent wiping performance.

  Incidentally, an ultrafine fiber multifilament composed of a combination of the radial segment 10 and the fan segment 11 can be obtained by splitting a composite fiber as shown in FIG.

  Such fibrillation of a composite fiber can be achieved by removing one component by dissolution or decomposition, swelling it with a swelling agent, conversely shrinking with a shrinking agent, or causing deformation or shrinkage by heating. Can be done. Moreover, a plurality of components can be physically divided by friction or impact. However, these divisions are usually performed after forming the fabric by weaving or knitting the composite fiber.

  As the ultrafine fiber multifilament that can be used in the present invention, the one shown in FIG. 2 is particularly suitable. As another example, the cross-sectional shape of the composite fiber before split fibril formation is, for example, FIG. ) To (f). Among these, (b) to (d) are particularly preferable. In addition, the thing of the said FIG.3 (d) becomes an ultrafine fiber multifilament which consists only of an inner side component (it consists of 12 segments) by melt | dissolving and removing an outer side component in a composite fiber.

To obtain a supernatant拭用fabric 1 using the above ultrafine fiber multifilament by fabric (reference embodiment), for example, plain weave, twill, is fabric made of satin, etc. weave and the like. The total fineness of the yarn used for the woven fabric is preferably 33 to 167 dtex, and the weave density is the sum of the cover factors (CF ₁ + CF ₂ ) determined by the following formula (1): It is preferable to set the density to 1800-3500.

As the knitted fabric used in the present invention, as already mentioned, tricot knitted fabric like et be. Among them, in particular, those of n / 1 satin (n is 3 or more) such as 3/1 satin, 4/1 satin, 5/1 satin, etc., the front yarn is greatly exposed on the surface layer. Thus, the wiping property is excellent. At this time, as the back yarn, the above-mentioned ultrafine fiber multifilament may be used, but a yarn having a relatively large fineness with a segment fineness of about 1 to 2 dtex may be used.

And as for the yarn used for the knitted fabric, both the ultrafine fiber multifilament used as the front yarn and the back yarn, both of which have a total fineness of 30 to 150 dtex, especially 30 to 50 dtex, have a wiping effect. Necessary in terms.

Further, the knitting density of the knitted fabric needs to be set at a course number of 40 to 90 / 2.54 cm and a wale number of 40 to 100 / 2.54 cm.

  Furthermore, in the present invention, a polishing agent can be contained in at least the surface of the wiping fabric 1. Examples of the polishing agent include silicone oils and various waxes. In particular, silicone oils are preferably used from the viewpoint of antifouling properties during use and easy handling. In order to contain the polishing agent on at least the surface of the wiping cloth 1, it is preferable that the wiping cloth 1 is dipped in a dispersion liquid in which the polishing agent is dispersed and dried. In addition, it is suitable on the effect that content of the said polish agent is set to 0.5 to 2 weight% with respect to fiber dry weight.

The surface of the wiping fabric 1 is raised. In the present invention, by the fluffed ultrafine fibers multifilament arranged on the surface even without low, manifested in more table edge portion of each segment, in order to exhibit excellent stain wiping performance and polished performance and brushed It is necessary .

For the formation of the raising layer, various conventional raising methods can be applied . For example , a sanding method for physically fluffing the surface of a knitted fabric or a needle raising method is preferable . The name you, brushed part of thickness, although it depends on the Qing拭用cloth 1 overall thickness, usually, it brushed not part 0.2~0.7mm the thickness of the (underlying fabric portion), brushed part of the thickness ( It is preferable to set the fluff length) to 0.1 to 0.5 mm.

  The elastic layer 2 provided on the back side of the wiping cloth 1 is made of an elastic material having cushioning properties. The elastic material is not particularly limited, and examples thereof include urethane sponge, rubber, fiber lump and the like. And it is suitable on the ease of use that the thickness sets to 3-8 mm. In addition, it is suitable for the said elastic material that it is equipped with the elastic characteristic of the grade which 30% compressive stress will be 2-15 kPa on the followable | trackability to a target object and durability with respect to repeated use.

  The synthetic resin sheet 3 and the pocket 4 provided on the back side are provided in consideration of the overall shape maintenance and workability, and are flexible but have a certain shape retaining property and are not easily contaminated. It is preferable that Examples of such a material include vinyl chloride and vinyl chloride foam. However, the materials of the synthetic resin sheet 3 and the pocket 4 are not necessarily the same as in the above example, and may be different from each other.

The portable shoe cleaner can be manufactured using the above materials, for example, as follows. That is, first, a tricot knitted fabric to be the wiping fabric 1 is prepared, which has at least the surface thereof provided with the special ultrafine fiber multifilament. And the raising | fluff process is given to the surface by the said appropriate method . Their to, this tricot knitted fabric, if necessary, by the inclusion of polishes by the method, to obtain a supernatant拭用fabric 1.

  Next, the wiping fabric 1, the hot melt adhesive (not shown in FIG. 1), the elastic material to be the elastic layer 2, the sheet material to be the synthetic resin sheet 3, and the sheet material to be the pocket 4 Are stacked in this order, punched into a predetermined shape with a mold, and the periphery thereof is cut by fusing with a high-frequency welder. In this way, the intended portable shoe cleaner can be obtained.

  Since the portable shoe cleaner thus obtained has a special ultrafine fiber multifilament formed by combining segments having edges extending in the longitudinal direction of the cloth on the surface of the wiping cloth 1, By wiping the surface of shoes or the like with this surface, the edge of the segment can be effectively wiped off, and the dirt can be captured and held between very fine fibers having a segment fineness of 0.3 dtex or less. It has become. Therefore, it has excellent dirt wiping performance and polishing performance that have never been seen before. In particular, when the wiping cloth 1 is raised and contains a polishing agent, the above polishing performance and the polishing effect of the polishing agent combine to further improve the finish of shoes and the like. Can do.

  And in the said portable shoe cleaner, since the dirt taken in by the cloth 1 for wiping can be easily removed by wiping by hand or washing with water, this surface is repeatedly used many times. It is economical because it does not waste resources.

  Furthermore, each segment of the ultrafine fiber multifilament is a very fine fiber having a segment fineness of 0.3 dtex or less, and the elasticity of the elastic layer 2 provided on the back surface side, and thus the unevenness A very good polishing performance can be achieved for a certain shoe surface.

  Further, as shown in FIG. 5, by inserting a finger into the pocket 4 provided on the back side of the synthetic resin sheet 3 on the further back side of the elastic layer 2, the dirt can be easily wiped and polished. Easy to use.

  In addition, the portable shoe cleaner of the present invention may be carried with the surface of the wiping cloth 1 folded inside, for example, but the surface of the wiping cloth 1 is completely covered. It is more hygienic to carry with you. Therefore, for example, as shown in FIG. 4, a storage bag 20 is prepared for storing the entire portable shoe cleaner, and the portable shoe cleaner is stored in the storage bag 20 when being carried. It is preferable to do.

  The storage bag 20 is preferably formed by using a synthetic resin sheet that is flexible to some extent in consideration of shape retention, antifouling properties, and flexibility. And it is suitable that it is transparent so that the contents can be seen at a glance.

  Further, in the above example, the pocket 4 that is slightly smaller than the synthetic resin sheet 3 is integrally laminated on the back surface of the synthetic resin sheet 3 and the fingers are inserted into this portion, but the fingers are inserted. The form to hold | maintain is not restricted to this, A suitable structure is employable. For example, as shown in FIG. 6 (a), the entire back surface of the synthetic resin sheet 3 is covered with another sheet 4a to form a double structure, and the fingers are inserted with one edge thereof being opened. Can be able to.

  Or as shown in FIG.6 (b), the strip | belt-shaped sheet | seat 4b may be provided in the back surface of the synthetic resin sheet 3, and you may make it insert a finger | toe inside this strip | belt-shaped sheet 4b.

  Next, examples of the present invention will be described together with comparative examples.

[Example 1]
As a front yarn, a 56 dtex / 25f composite fiber having a cross section shown in FIG. 3 (a) (KB Selen Co., Ltd., Belima X: registered trademark, radial part is polyamide, segment fineness is 0.3 dtex, fan part is A regular polyester yarn having a segment fineness of 0.1 dtex and a back yarn of 33 dtex / 12f was prepared. These yarns were knitted into a tricot 3/1 satin with a course number of 80 / 2.54 cm and a wale number of 23 / 2.54 cm to obtain a tricot knitted fabric.

  Then, the obtained knitted fabric was immersed in benzyl alcohol, and the front yarn was opened to form an ultrafine fiber multifilament, which was then sanded to raise the surface. The thickness of the raised portion was about 0.3 mm, the thickness of the non-raised portion was 0.4 to 0.5 mm, and the thickness of the entire knitted fabric was about 0.7 to 0.8 mm. Further, the stretch rate of the brushed knitted fabric [JIS L1096 8.14.1 stretch rate B method (constant load method)] was 8.5% in the course direction and 26.5% in the wale direction. The stretch recovery rate of this knitted fabric [JIS L1096 8.14.2 stretch recovery rate B-1 method (constant load method)] is 30 seconds later, the course direction: 80.6%, the wale direction: The value after 60 minutes was 72.7%, the course direction: 91.7%, and the wale direction was 90.9%.

  This knitted fabric is dipped in a 1.5% by weight solution of an aqueous emulsion of a silicone-based oil (manufactured by Meisei Chemical Industry Co., Ltd., High Softer K-45) and dried to dry the silicone oil as a polish agent (Pickup rate 60%, content ratio of silicone oil to 0.9% by weight of fiber dry weight).

  Next, the knitted fabric was used as a wiping fabric 1 (see FIG. 1), and an elastic layer 2 (thickness 4 mm) made of urethane sponge was laminated on the back surface of the knitted fabric through a hot melt adhesive. Then, on the back side, a synthetic resin sheet 3 made of vinyl chloride (thickness 0.5 mm) and a pocket 4 made of vinyl chloride (thickness 0.5 mm) are laminated, and the laminate is punched with a mold. Then, cutting with a high frequency welder was cut to obtain a portable shoe cleaner as shown in FIG. This is 10 cm long, 8 cm wide and 0.6 cm thick, and is set to a compact and easy to use size.

  Using this portable shoe cleaner, I polished the cowhide leather shoes that I used for going out for 3 hours and 5 times. The result was good and the finish was good. And after using, once removing dirt and using it for the wiping of dirty shoes similarly 10 times, the wiping effect and the glazing effect were maintained until the end.

[Example 2]
The concentration of the aqueous emulsion of the silicone oil used as a polishing agent was 0.5% by weight (pickup rate 60%, content of silicone oil with respect to fiber dry weight was 0.3% by weight). Other than that was carried out similarly to the said Example 1, and obtained the portable shoe cleaner. Although this product and the glossing effect were somewhat weak, the same effect as the product of Example 1 was achieved.

[Comparative Example 1]
As the front yarn, a 33 dtex / 12f regular polyester yarn was used instead of the ultrafine fiber multifilament. Other than that was carried out similarly to the said Example 1, and obtained the portable shoe cleaner. This was used in the same manner as in Example 1, but the wiping effect and the glossing effect were insufficient.
