JP7565026B2 - Water-repellent sheet material for gloves, gloves, hand mold for manufacturing gloves, and manufacturing method for gloves - Google Patents

Description

The present invention relates to a water-repellent sheet material for gloves , for example, made of a flexible material such as resin or rubber in sheet form, gloves, a hand mold for manufacturing gloves, and a method for manufacturing gloves.

For example, food gloves (Patent Document 1) are known that have multiple protrusions on the palm surface to prevent rice grains from adhering to the surface. The multiple protrusions of the glove in Patent Document 1 are formed by applying a double embossing process to the surface of a base material made of a thermoplastic elastomer or the like. The length of a rice grain is about 7000 μm, and the width of the protrusions is set to about 3500 μm, which is smaller than that. By providing multiple protrusions with a width of about half the width of a rice grain on the palm surface at intervals narrower than the length of the rice grain, as in the glove in Patent Document 1, the area where the rice grain comes into contact with the palm surface can be reduced, making it difficult for the rice grain to adhere to the palm surface.

Patent Document 1 states that the width of the protrusions is 350 μm, but it is unrealistic to form protrusions with a width of 350 μm by embossing the surface of a thermoplastic elastomer. Patent Document 1 also states that fine protrusions with a width of 5 μm are provided on the surface of these protrusions, but such fine protrusions cannot be formed by embossing. Furthermore, from the description in Figure 1(c) of Patent Document 1, it can be seen that the width of the protrusions is about half the length of the rice grain K. Therefore, the description of the width of the protrusions in Patent Document 1 is incorrect, and it is believed that the width of the protrusions is about 3,500 μm.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in Fig. 1, a glove 10 according to an embodiment of the present invention has a base material 2 formed from a thin sheet-like material of a substantially uniform thickness into a three-dimensional glove-like shape that covers a human hand. The glove 10 has a plurality of fine hair-like projections 4 integrally formed on the entire outer surface 2a of the base material 2. In this embodiment, the glove 10 (base material 2 and hair-like projections 4) is formed from a single flexible material that easily fits the hand. In this embodiment, polyvinyl chloride mixed with a plasticizer and a stabilizer (such flexible polyvinyl chloride will be simply referred to as polyvinyl chloride in the following description) is used as such a flexible material.

The thickness of the substrate 2 is 10 μm to 5000 μm. The multiple trichomes 4 are formed by integrally protruding the material of the substrate 2 from its surface 2a. The trichomes 4 can be provided only partially in a desired area of the surface 2a, rather than being provided on the entire surface 2a of the substrate 2 as in this embodiment. In addition, a glove 10 having multiple trichomes 4 on its surface 2a can be turned inside out to produce a glove 10' (not shown) having multiple trichomes 4 on its inner surface. In the claims, the term "surface of the substrate" includes both the surface 2a of the substrate 2 and the other surface opposite to the surface 2a (hereinafter referred to as the inner surface).

As shown in FIG. 2, the multiple hair-like projections 4 are provided at a substantially uniform density on the surface 2a of the base material 2 of the glove 10. The shape, arrangement area, size, density, etc. of the hair-like projections 4 are determined by the shape, layout, size, density, etc. of the multiple fine holes 26 (FIG. 4) that are generated on the surface 24a of the plating layer 24 provided on the surface 22a of the base material 22 of the hand mold 20 described later. In other words, the multiple hair-like projections 4 of the glove 10 have a shape that is a transfer of the inner shape of each of the multiple holes 26 of the hand mold 20 described later.

The spacing between the multiple trichomes 4 is 0.1 μm to 1000 μm. The spacing between the trichomes 4 here and in the claims refers to the distance between the central axes of two adjacent trichomes 4 when the trichomes are likened to a cone. The height to which each trichome 4 protrudes from the surface 2a of the substrate 2 is 0.1 to 5.0 times the spacing between the trichomes described above.

The trichomes 4 also have a shape that tapers away from the surface 2a of the substrate 2. In this embodiment, the trichomes 4 have a shape that is roughly conical or roughly truncated conical. In FIG. 1, the trichomes 4 are shown enlarged for ease of explanation, but in reality, they are so minute that they cannot be seen with the naked eye, and the size and shape of the trichomes 4 in FIG. 1 differ from the actual ones.

As shown in Figures 3 and 4, the hand mold 20 for manufacturing the glove 10 has a plated layer 24 of a substantially uniform thickness over the entire surface 2a of the substrate 22. In Figure 4, the plated layer 24 is illustrated with a thickness different from the actual thickness for ease of understanding. The plated layer 24 has a plurality of fine holes 26 over its entirety. Each hole 26 has an opening 26a on the surface 24a of the plated layer 24, and has a shape that tapers toward the substrate 22 as it moves away from the surface 24a. In this embodiment, the opening 26a is substantially circular in shape, and the hole 26 is substantially conical in shape.

The holes 26 have an opening 26a with a diameter of 0.1 μm to 1000 μm, and the spacing between adjacent openings 26a is 0.1 μm to 1000 μm. The spacing between the openings 26a referred to here is the spacing between the holes in the claims, and refers to the distance between the central axes of two adjacent holes 26. The depth of the holes 26 is the depth from the surface 24a of the plating layer 24, and is 0.1 to 5.0 times the spacing between the holes described above. In FIG. 3, the holes 26 are shown enlarged for ease of explanation, but in reality they are so tiny that they cannot be seen with the naked eye, and the size of the holes 26 in FIG. 3 differs from the actual size.

The hand mold 20 can be manufactured, for example, by forming a porous plating layer (plating layer 24 having a plurality of holes 26 on surface 24a) on surface 22a of conductive base material 22 shaped like a human hand. In addition, even if the base material is not conductive, the hand mold 20 can be manufactured by forming a porous plating layer 24 on the surface of a base material that has been subjected to a conductive coating treatment.

The technology for forming a porous plating layer 24 having a plurality of holes 26 on the surface 22a of the substrate 22 is disclosed, for example, in Patent Nos. 5758557 and 6621169. With this technology, the above-mentioned plurality of fine holes 26 can be formed on the surface of the hand mold 20 (surface 24a of the plating layer 24). The technology for forming the porous plating layer 24 and the plurality of holes 26 on the surface 22a of the substrate 22 is a publicly known technology, so a detailed description thereof will be omitted here.

A method for manufacturing the glove 10 described above will now be described.
First, a hand mold 20 having the above-mentioned multiple fine holes 26 on its surface 24a is prepared. Polyvinyl chloride is also prepared by applying heat to turn it into a sol. The sol-like polyvinyl chloride is then applied to the entire surface of the hand mold 20 (surface 24a of the plating layer 24). Alternatively, the hand mold 20 is immersed in the sol-like polyvinyl chloride. In the claims, "application" includes immersing the hand mold 20 in a sol-like material.

The polyvinyl chloride is then baked to solidify, and peeled off from the hand mold 20. At this time, the glove-shaped polyvinyl chloride is peeled off from the hand mold 20 while being turned inside out. This allows the production of a glove 10 having a plurality of fine hair-like projections 4 on the surface 2a of the base material 2. Note that by further turning this glove 10 inside out, it is also possible to produce a glove 10' (not shown) having a plurality of fine hair-like projections 4 on the inner surface.

The multiple hair-like projections 4 formed on the surface 2a of the glove 10 have a shape that is a transfer of the inner shape of the multiple fine holes 26 on the surface 24a of the hand mold 20, and are arranged at approximately the same intervals as the intervals between the holes 26. Since the size of the holes 26 is extremely small, it is possible that the polyvinyl chloride does not reach the tip of the holes 26. In addition, the holes 26 themselves tend to be rounded at the bottom rather than conical. For this reason, the hair-like projections 4 peeled off from the holes 26 tend to be formed into an approximately truncated cone shape with a slightly rounded tip rather than a pointed shape. From another perspective, the hair-like projections 4 of the glove 10 of this embodiment manufactured using the above-mentioned hand mold 20 are characterized by their tendency to be approximately truncated cone shape with a slightly rounded tip.

Next, the functions and effects of the glove 10 described above will be described.
Since the hair-like projections 4 repel water droplets, the glove 10 having the above-mentioned plurality of hair-like projections 4 on the surface 2a is less likely to get wet and is less likely to get dirty. For example, when the glove 10 of this embodiment is used to wash dishes, the surface 2a of the glove 10 becomes dry immediately after washing, and the glove 10 can be put away in a drawer or the like. Therefore, the glove 10 of this embodiment can maintain a clean state for a long time.

In addition, gloves 10' having hair-like projections 4 on the inner surface are less likely to cause the blocking phenomenon in which gloves 10' stick to the surface of the hand when putting on or taking off, making it easier to put on and take off gloves 10'. In addition, gloves 10' having hair-like projections 4 on the inner surface have a smooth feel like suede, are not sticky, and are comfortable to wear.

In addition, since the multiple hair-like projections 4 are integrally formed by protruding the material of the substrate 2 from the surface 2a (or the inner surface when turned inside out) of the substrate 2, the gloves have excellent durability, and the hair-like projections 4 do not peel off from the substrate 2 even with repeated use. Therefore, the gloves 10 of this embodiment can maintain their water-repellent performance for a long period of time, and because they repel water droplets, they can maintain a state in which they are difficult to get wet and difficult to get dirty for a long period of time. In addition, the gloves 10' having multiple hair-like projections 4 on the inner surface can maintain a good feel on the skin for a long period of time.

Furthermore, when gloves 10, 10' are manufactured using a hand mold 20 having a plurality of minute holes 26 on the surface 24a as in this embodiment, a plurality of trichomes 4 can be formed simultaneously and uniformly over the entire surface 2a of the base material 2 of the glove 10 having a three-dimensional shape (or the inner surface of the base material 2 of the glove 10'). In other words, according to the manufacturing method of this embodiment, the manufacturing process of gloves 10, 10' can be extremely simplified, and the manufacturing cost of gloves 10, 10' can be reduced. Furthermore, according to the manufacturing method of this embodiment, the shape reproducibility of the trichomes 4 can be improved, and quality variation can be eliminated.

In this case, all of the hair-like projections 4 can be provided substantially perpendicularly to the surface 2a of the substrate 2 of the glove 10 having a three-dimensional shape, and the hair-like projections 4 can be provided over the entire surface 2a of the substrate 2, protruding substantially perpendicularly from the surface 2a. For example, even in areas where it is difficult to form fine projections, such as between the fingers or at the fingertips, hair-like projections of the same shape and density can be provided as on the palm or back of the hand, and the same water-repellent properties can be provided in all areas of the surface 2a of the glove 10. In addition, if the glove 10' is turned inside out, even between the fingers and at the fingertips, a smooth texture equivalent to that of the palm or back of the hand can be obtained, and blocking phenomena in narrow areas such as the fingertips can be effectively suppressed.

It is known that the contact angle of water with the surface of a material is used as a criterion for evaluating the water repellency of materials such as the gloves 10 of this embodiment, raincoats, and umbrellas. In the gloves 10 of this embodiment, the spacing and height of the multiple hair-like projections 4 provided on the surface 2a of the substrate 2 are set so that the "contact angle" of water at a temperature of 23°C and a humidity of 50% RH is 110 degrees or more, which satisfies the criterion for good water repellency.

As described above, the bristles 4 of the glove 10 of this embodiment have a shape that is a transfer of the inner shape of the multiple fine holes 26 formed on the surface 24a of the hand mold 20. Therefore, in practice, the spacing and height of the multiple bristles 4 are approximately the same as the spacing and depth of the multiple holes 26 in the hand mold 20. In other words, by controlling the shape (spacing and depth) of the multiple holes 26 in the hand mold 20, it is possible to manufacture a glove 10 with high water repellency, or a glove 10' that has a smooth feel.

In order to investigate the optimal spacing and height of the trichomes 4 that can exhibit good water-repellent performance, the inventors of the present application created a mold sample in which a porous plating layer was formed on the surface of a copper plate and multiple fine holes 26 were formed on the surface 24a of the plating layer 24. Multiple types of mold samples were created by varying the hole diameter and depth of the multiple holes 26. Then, in order to evaluate the water-repellent performance of the trichomes 4 manufactured using these multiple types of mold samples, the material film having the manufactured trichomes 4 was wetted with water and the contact angle of a water droplet attached to the surface was observed under a microscope. Note that flexible polyvinyl chloride was used to manufacture the material film of the trichomes 4. An example of an evaluation test is described below.

(Preparation of Ni plating solution)
Nickel chloride [ _NiCl2.6H2O ]: 0.1 M (mol/L) and _{ammonium chloride [NH4Cl ]} : 2.0 M (mol/L) were dissolved in ion-exchanged water, and 28% by mass of ammonia water was added to the aqueous solution thus obtained to adjust the pH of the Ni plating solution. In this way, several types of Ni plating solutions with different pH values were prepared.

(Electrolytic degreasing treatment)
A number of copper plates measuring 70 mm x 120 mm x 0.3 mm were prepared as substrates for mold samples, and were immersed in an aqueous solution at 50°C in which an electrolytic degreaser "Pakuna THE-210" manufactured by Yuken Kogyo Co., Ltd. was dissolved at a concentration of 50 g/L. Then, each copper plate was used as a cathode, and a degreasing treatment was performed by passing a current at a cathode current density of 5 A/ ^dm2 for 60 seconds. Thereafter, the degreased copper plates were washed three times with ion-exchanged water, and then immersed in a 10 vol% aqueous sulfuric acid solution at room temperature for 60 seconds for acid cleaning. Furthermore, each copper plate was washed three times with ion-exchanged water.

(Formation of Ni plating layer)
The copper plates electrolytically degreased as described above were immersed one by one in the above-mentioned various types of Ni plating solutions kept at 30°C. Then, while performing air agitation, the cathode current density was varied for each copper plate, and electric Ni plating was performed for 300 seconds. Next, each plated copper plate was washed three times with ion-exchanged water, and then immersed in a 50°C aqueous sodium hydroxide solution (50g/L) for 60 seconds. Furthermore, each copper plate was washed three times with ion-exchanged water, immersed in 50°C ion-exchanged water, and ultrasonically cleaned for 60 seconds to obtain multiple plated products as mold samples.

On the plated surface of each mold sample, multiple fine holes were formed, with shapes according to the type of plating solution and plating conditions. The ammonia content of the plating solution was changed for each mold sample, and the cathode current density as a plating condition was changed for each mold sample, so the holes formed on the surface of each mold sample had different hole diameters and depths. Here, ten types of mold samples were prepared, with holes 26 having different diameters and depths.

When producing the multiple mold samples described above, the target values for the hole diameter and depth of the multiple micro holes to be formed on the surface of the mold sample were determined in advance, and the pH of the plating solution and plating conditions were determined according to the target values for each mold sample. Here, when producing 10 types of mold samples, the target values for the hole diameter and depth were set as shown in Table 1 below.

(Evaluation of Ni plating layer)
A number of holes were randomly selected from the secondary electron images of each mold sample that was actually produced, and the diameter (hole diameter), depth, and spacing of the holes were measured. The hole diameter, depth, and spacing were measured by randomly selecting 10 holes for each mold sample, using a laser microscope LEXT OLS4100 (manufactured by Olympus Corporation), and the average values were calculated. Note that since the holes are not all perfect circles, the longest distance between two points on the circumference of each hole was regarded as the hole diameter. The measurement results are shown in Table 1 below.

A material film having multiple hair-like projections was created using the 10 types of mold samples (Examples 1 to 10) described above. Flexible polyvinyl chloride resin was used as the material for the material film. An example of a method for producing a material film using the above-mentioned mold samples is described below.

(Preparation of polyvinyl chloride sol)
A polyvinyl chloride sol was prepared by mixing and stirring 100 parts by mass of polyvinyl chloride (trade name "PSM-30" manufactured by Kaneka Corporation), 100 parts by mass of a plasticizer (trade name "Mesamoll" manufactured by LANXESS Corporation), 5 parts by mass of epoxidized soybean oil (trade name "Adeka Cizer O-130P" manufactured by ADEKA Corporation), 5 parts by mass of a viscosity adjuster (trade name "LeoSeal QS-102" manufactured by Tokuyama Corporation), and 3 parts by mass of titanium dioxide (manufactured by Ishihara Sangyo Kaisha, Ltd.).

(Preparation of base film)
The above-mentioned 10 kinds of mold samples were preheated until the surface temperature reached 60°C, and the above-mentioned polyvinyl chloride sol was applied to the surface of each mold sample. Then, the 10 kinds of mold samples with the polyvinyl chloride sol applied to the surface were heated at 200°C for 3 minutes and allowed to cool, so that the material applied to the mold sample was solidified. After that, the material was peeled off from the surface of each mold sample to obtain a material film.

(Evaluation of the material film)
For each of the prepared material films, the height, interval, and tip width of the trichomes transferred to the surface were measured using a laser microscope LEXT OLS4100 (Olympus Corporation). The measurement results are shown in Table 2 below for each mold sample used. The height referred to here is the protruding height from the surface of the material film, and the tip width is the width of the tip surface of the trichomes having an approximately truncated cone shape.

(Contact angle test)
The contact angle of water on the surface of the material film prepared as described above was examined to evaluate the water repellency. As a comparative example, a material film without hair-like protrusions was prepared from the same material using a ceramic plate without a Ni plating layer formed on the surface.

The contact angle was measured using a contact angle meter DMe-211 (Kyowa Interface Science Co., Ltd.) in an environment of 23°C temperature and 50% RH by depositing an 8 μL droplet of pure water with a syringe-type dispenser onto the surface of a horizontally placed sample, and an image was taken from directly beside it with a CCD camera. The contact angle was calculated by analyzing the outline shape of the droplet from the image obtained.

The average values of the water contact angles measured 10 times for Examples 1 to 10 are summarized in Table 3 below.

(Evaluation of Water Repellency)
As described above, it was found that all of Examples 1 to 10 satisfied the standard for good water repellency (110 degrees or more). The shortest interval between the trichomes was 8.58 μm (Example 1) and the longest was 94.41 μm (Example 10). In addition, when the ratio of the interval to the height of the trichomes was examined for each Example, the height of the trichomes was in the range of 0.51 times (Example 1) to 1.45 times (Example 5) the interval between the trichomes. Therefore, it was found that good water repellency can be achieved by manufacturing the glove 10 so that the interval and height of the trichomes are within this range.

In addition to the above-mentioned Examples 1 to 10, material films were created with various changes to the spacing and height of the trichomes, and the water-repellent performance was measured. It was found that the water-repellent performance standard was met even when the spacing between the trichomes was shortened to 0.1 μm. It was also found that the water-repellent performance standard was met even when the spacing between the trichomes was lengthened to 1000 μm. In other words, the appropriate spacing between the trichomes can be 0.1 μm to 1000 μm, preferably 1.0 μm to 500 μm, and more preferably 5 μm to 100 μm.

In addition, when the height of the trichomes was varied from as low as 0.1 to as high as 5.0 times the spacing between the trichomes, the water-repellent performance was examined, and it was found that the standard for water-repellent performance was met when the spacing between the trichomes was within the above-mentioned range. Therefore, the appropriate height of the trichomes can be 0.1 to 5.0 times the spacing between the trichomes, preferably 0.3 to 3.0 times, and more preferably 0.5 to 2.0 times.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above-mentioned embodiments, and various modifications and applications are possible within the scope of the gist of the present invention.

For example, in the above-mentioned embodiment, the case where the bristles 4 are provided on the surface of the gloves 10, 10' has been described, but the present invention is not limited to this, and the bristles 4 may be provided on the surface of the material of rain gear such as a raincoat or an umbrella.
