The present disclosure relates to a field of labor protection appliances, and more particularly to a fully coated glove having a moisture wicking property.
It is well known that safety protection is very important in modern industrial production, and wearing protective glove is an important part of the safety protection. The commercially available coated labor safety gloves are divided into a fully coated type and a palm coated type. Main components of the coating of the palm coated type labor protection glove are nitrile, natural latex, PVC, and polyurethane. Wearing such glove can achieve a certain level of protection, while it is helpless against the intrusion of external liquids or bacteria since a back of the hand is not coated. For certain occasions, such as a working environment being relatively humid or having oil pollution such as lubricating oil, and in cases where there is a risk of bacteria or virus intrusion such as contact with medical waste, it is necessary to maintain a good shield coating between the hands and external objects. Accordingly, the palm coated type glove is obviously not suitable, and the fully coated type glove is a must-worn. Main raw materials of a coating of the fully coated type glove are nitrile, natural latex, and PVC. Because of the need to shield the intrusion of the external liquids or bacteria, all such commercially available products currently do not have a moisture wicking property, and the hand feeling is relatively hard, so that the wearing experience may be very uncomfortable. When wearing such gloves for a long time, the skin of the hands is soaked in sweat, which may easily cause skin wrinkles. In addition, such gloves easily become breeding grounds for bacterial and increase work fatigue.
The purpose of the present disclosure is to provide a fully coated glove having a moisture wicking property.
The inventor has studied and found that a principle of waterproof and moisture wicking property of a coating is that the moisture wicking property of a film is achieved through two ways. One is non-porous and hydrophilic. A water molecule is composed of one oxygen atom and two hydrogen atoms. When the water molecule is in a gaseous state, there is almost no force between the water molecules, and the water molecule can move freely. When the water molecules inside a shielding layer come into contact with the film in gaseous form, hydrophilic groups contained in the film can absorb the water molecules, and transfer the water molecules from an inner layer with high concentration to an outer layer with low concentration through a molecular chain, and then the water molecules are volatilized into the air, so as to complete a complete process of adsorption-transfer-desorption. At this time, the shielding layer produces phenomenon of moisture absorption and breathability. The concentration and temperature difference of water molecules inside and outside the shielding layer are the influencing factors of the conduction rate. The greater the difference, the faster the conduction rate. However, when the water molecule is in a liquid state, a bonding force between molecules is relatively large, including van der Waals force and hydrogen bonds. Therefore, although the hydrophilic groups in the film are in contact with liquid water, the adsorption force between the shielding layer and the water molecules is less than the binding force between the water molecules, so that the liquid water cannot be conducted to the other side through the shielding layer. At this time, the shielding layer plays a role of waterproofing. In addition, because the shielding layer is a non-porous design, bacteria and viruses cannot pass through the shielding layer, which is the principle that the shielding layer is not only breathable, but also waterproof and anti-virus. The second way to achieve the moisture wicking property of the film is using microporous evacuation. A moisture wicking layer of the present disclosure adopts such method. When a hand of a wearer generates sweat, a volume of a gaseous water molecule is much smaller than an aperture of the micropore, so that the gaseous water can freely contact the shielding layer through the moisture wicking layer, and then diffuse to the outside of the glove through the shielding layer. However, if an amount of the sweat generated is greater than a diffusion speed of the shielding layer, the microporous moisture wicking coating can temporarily absorb and store excess sweat. In addition, the moisture wicking coating of the present disclosure concurrently has the hydrophilic groups, so that it has both microporous hydrophobic and hydrophilic moisture absorption functions, and can slow down or even eliminate the stuffy and wet feeling of hands caused by sweat as much as possible.
According to the above principles, a hydrophilic property of the coating in contact with the skin and a number of micropores play important roles. At present, a raw material of fully coated products that are commercially available is nitrile or PVC. From the point of view of the structures of these two raw materials, these two raw materials are relatively poor hydrophilic. Especially, the PVC material is not hydrophilic at all. According to the analysis of the process, these two materials do not have a foam process and a foam section. Therefore, the hydrophilicity and micropores of the fully coated glove made of these two raw materials are not enough, or even not, resulting in glove that does not have moisture absorption effect and the feel is relatively hard.
This present disclosure uses polyurethane as a raw material for the inner layer, which solves the problems of hydrophilicity and moisture wicking from the chemical composition and physical structure. First of all, from the perspective of chemical composition, the commercially available polyurethane raw materials are divided into two types, i.e., a solvent-based type and a waterborne type. No matter which type, they all have a certain number of hydrophilic groups, e.g., carboxyl, hydroxyl or amino groups, and these groups can strongly adsorb gaseous water molecules. From the point of view of physical structure, during processes of water-washing and film-forming of solvent-based polyurethane after coating, due to an exchange of solvent and water, the resulting polyurethane film forms a large number of fine pores. However, a process of physical foaming before molding is adopted for waterborne polyurethane, so that the waterborne polyurethane also contains a large number of fine pores. These fine pores have two advantages. One is that a specific surface area of the coating is greatly increased, that is, a contact area between the water molecule and the hydrophilic material is increased. In this way, during the use of glove, the gaseous sweat can maximize the contact with the hydrophilic groups of the coating and be absorbed, and then be channeled to the outside of the glove through the shielding layer. If the sweat is generated faster than it is discharged, excess sweat will be attracted by a large number of microporous capillaries, and held by the coating and fibers so as to be mechanically held in the capillaries between the fibers. The other is because there are the large numbers of fine pores, softness of the coating is greatly improved. This is a very important indicator in an actual use of glove. Soft glove can reduce the fatigue of hands during work and reduce labor intensity to the greatest extent.
The present disclosure is achieved through the following technical solutions:
In one aspect, the present disclosure provides a fully coated glove having a moisture wicking property, which includes a palm body that is knitted, a moisture wicking layer fully coated on an inner surface of the palm body, a shielding layer fully coated on an outer surface of the palm body, each of the moisture wicking layer and the shielding layer is prepared by coating using a raw materials including waterborne polyurethane or solvent-based polyurethane, the moisture wicking layer is a foam layer with a thickness of 0.1 mm to 0.3 mm, the shielding layer is a non-foam layer with a thickness of 0.03 mm to 0.2 mm, and the specific preparation process of the fully coated glove includes following steps: molding of the palm body; preparing the moisture wicking layer that is foamed by coating; water washing; drying; preparing the shielding layer that is not foamed by coating; drying; demolding of the finished product; and packaging. When a second coating layer that is the shielding layer is coat, a first layer that is the moisture wicking layer is ensured to be cured and dried into a film, and a surface energy of a shielding layer coating in a liquid state is ensured to be lower than the surface energy of the moisture wicking layer, so that the shielding layer coating infiltrates into a surface of the moisture wicking layer at a maximum level and even into micropores of a surface layer. Because the low surface energy can make the shielding coating material soak into the surface of the moisture wicking layer or even the micropores of the surface layer to the greatest extent, through sufficient interfacial contact, it is absorbed by the moisture wicking layer. During the subsequent heating process, the shielding layer rubber under the action of Brownian motion, the molecules are closely combined with the molecules of the moisture wicking layer, and the two-layer coating forms a stable state under the joint action of Van der Waals force and hydrogen bonds. Therefore, strictly controlling the surface energy of the shielding layer is the key to making the two-layer coating have high bonding strength.
In certain embodiments, when the shielding layer is prepared by coating using the raw material including a waterborne polyurethane resin, a solid content of the coating is maintained between 20% and 40% and a viscosity of the coating is maintained between 500 centipoises and 2000 centipoises so as to ensure that the thickness of the shielding layer is 0.03 mm to 0.2 mm; when the shielding layer is prepared by coating using the raw material including a solvent-based polyurethane resin, the solid content of the coating is maintained between 12% and 20% and the viscosity of the coating is maintained between 300 centipoises and 1500 centipoises.

In certain embodiments, when the moisture wicking layer is prepared by coating using raw material including a waterborne polyurethane resin, a solid content of the coating is maintained between 20% and 40%, a viscosity is maintained between 500 centipoises and 2000 centipoises and an expansion ratio is maintained between 1.15-1.8 so as to ensure that the moisture wicking layer with the thickness of 0.1 mm to 0.3 mm; because for waterborne polyurethane resin, the coating thickness can be freely maintained between 0.1 mm to 0.3 mm when the solid content of the coating is maintained between 20% and 40% and the viscosity is maintained between 500 centipoises and 1500 centipoises; when the moisture wicking layer are prepared by coating using raw materials including a solvent-based polyurethane resin, solid content of the coating is maintained between 12% and 18% and the viscosity of the coating is maintained between 500 centipoises and 1500 centipoises; because according to the foaming principle of solvent-based resin, by adjusting the solid content of the resin, adding a solidification speed regulator and a cell regulator, by adding a solidification speed regulator, the solidification speed of the resin after entering the water can be changed, so that the surface layer resin density decreases. At the same time, add cell aid to reduce the probability of large-diameter fine pores, and the appropriate range of the solid content of the coating is maintained between 12% and 18%. At the same time, control the viscosity between 500 centipoises and 1500 centipoises, the coating thickness can be freely maintained between 0.1 mm to 0.3 mm.

When making fully coated glove, the formulas of the raw materials used for the moisture wicking layer and the shielding layer can be combined arbitrarily according to needs.
The above parameters were chosen for the following reasons:
1. For the moisture wicking layer, two points need to be paid attention to.
(1) The size and the number of the pores. The pores of the moisture wicking coating per unit volume are within a reasonable range. If the number is larger, the pores size is smaller, indicating that the specific surface area of the pores is larger, which is beneficial to moisture wicking property (it should be noted here that the size of the pores is not smaller than a range that hinders a free passage of water vapor molecules). If the moisture wicking layer is made of the waterborne polyurethane, we believe that a foam ratio is between 1.15 and 1.8, which is a reasonable range, and the number and diameter of pores can be controlled by the amount of foam agent added. The amount of foam agent added is generally 5% to 15% of the amount of resin. If the moisture wicking layer is prepared with the solvent-based polyurethane, according to the foaming principle of solvent-based resin, a desired goal can be achieved by adjusting a solid content of the coating, and adding a solidification speed regulator and a cell regulator. Conventional solvent-based polyurethane glove resin, a solidification speed of the surface after entering the water is very fast, resulting in a very dense coating surface similar to the plastic skin. By adding a solidification speed regulator, the solidification speed of the resin after entering the water can be changed, so that the resin density of the surface layer decreases. At the same time, a cell adjustment additive is added to reduce the probability of large-diameter cells, and the control range of the solid content of the coating is more appropriate to be maintained between 12% and 18%. Combining the above three factors, the specific surface area of the entire moisture wicking layer can be controlled within a reasonable range.
(2) The thickness of the coating, because there are a large number of tiny holes, the thickness of the coating has a slight influence on the breathability of the moisture wicking layer, because the thicker the thickness, the longer the path for the water molecules to pass through the coating, which is not conducive to breathability. For moisture absorption, under the premise that the number of pores per unit volume is constant, the thicker the coating, that is, the more storage space that can be used to absorb and lock moisture, so it is beneficial to moisture absorption. But similar to the shielding layer, a thicker coating will also have a negative impact on the dexterity and touch of the fingers. Through certification, we believe that it is more appropriate to control the thickness of the coating between 0.1 mm and 0.3 mm. When specifying the production process, the thickness of the coating can be achieved by adjusting the viscosity and solid content of the coating. For the same viscosity, the higher the solid content of the coating, the thicker the coating; for the same solid content, the higher the viscosity of the coating, the thicker the coating. For the waterborne polyurethane resin, the solid content of the coating is 20% to 40%, the viscosity is between 500 centipoises and 2000 centipoises, and the foam ratio is maintained between 1.15 and 1.8, so that the coating thickness can be freely maintained between 0.1 mm and 0.3 mm. For the solvent-based polyurethane, the solid content of the coating is 12% to 18%, the viscosity is between 500 centipoises and 1500 centipoises, and the coating thickness can be freely maintained between 0.1 mm and 0.3 mm.
2. For the shielding layer, we need to strictly control the thickness of the coating. A thick coating is beneficial to the shielding effect, but the disadvantage is that the path of water molecules passing through the shielding layer are lengthened in terms of breathability, which reduces the breathability of the coating. In addition, the thick coating also negatively affects the dexterity and tactility of the fingers of the wearer during work. With a thin coating, the path of the water molecules passing through the shielding layer becomes shorter, which increases the breathability of the coating and sensitivity to touch. The disadvantage is that the continuous shielding effect may be reduced. In addition, it will also have a serious negative impact on the durability of the glove. Therefore, it is more critical to select an appropriate coating thickness. Through certification, it is considered that the thickness of the coating should be controlled between 0.03 mm and 0.2 mm. When specifying the production process, the thickness of the coating can also be achieved by adjusting the viscosity and solid content of the coating. For the waterborne polyurethane resin, the solid content of the coating is 20% to 40%, and the viscosity is between 500 centipoises and 2000 centipoises. For the solvent-based polyurethane, the solid content of the coating is 12% to 20%, and the viscosity is between 300 centipoises and 1500 centipoises, so that the coating thickness can be freely maintained between 0.03 mm and 0.2 mm.
3. Adhesion strength between the moisture wicking layer and the shielding layer. The principle of bonding is that after two layers of adherents are in contact with each other, a force is generated between the molecules, so that the two adherents are combined. Specifically, in the process of the present disclosure, when the second layer of glue (shielding layer) is coating, the first moisture wicking layer has been cured and dried to form a film. To improve the bonding strength between the moisture wicking layer and the shielding layer, it is necessary to have the surface energy of the liquid shielding layer coating lower than that of the moisture wicking layer. Because the low surface energy can make the shielding coating material soak into the surface of the moisture wicking layer to the greatest extent or even into the micropores of the surface layer, and be absorbed by moisture wicking layer through sufficient interface contact. During the subsequent heating process, the rubber molecules of the shielding layer are closely combined with the molecules of the moisture wicking layer under an action of Brownian motion. Therefore, strictly controlling the surface energy of the shielding layer is the key to making the two-layer coating have high bonding strength.
The beneficial effect of the present disclosure is that:
The fully coated gloves having the moisture wicking property of the present disclosure have an ingenious structure. Aiming at the deficiencies of various gloves currently on the market, the present disclosure adopts the method of secondary coating to creatively achieve moisture absorption, breathability and shielding isolation. Such functions are combined into one glove, which perfectly solves the shortcomings of the market. The present disclosure uses polyurethane as the coating raw material, and organically combines the foam coating (mainly for moisture wicking property) and the non-foam coating (mainly for shielding and isolation functions), so that the product has functions of moisture wicking property and shielding isolation, and soft hands feeling, which greatly reduces the fatigue of work. It has a wider application range and strong practicability, worth promoting.

Because the low surface energy can make the shielding coating material soak into the surface of the moisture wicking layer or even the micropores of the surface layer to the greatest extent, through sufficient interfacial contact, it is absorbed by the moisture wicking layer. During the subsequent heating process, the shielding layer rubber under the action of Brownian motion, the molecules are closely combined with the molecules of the moisture wicking layer, and the two-layer coating forms a stable state under the joint action of Van der Waals force and hydrogen bonds. Therefore, strictly controlling the surface energy of the shielding layer is the key to making the two-layer coating have high bonding strength.

Performance testing standards:
The result of the performance test of the fully coated glove of each example is as shown in Table 1:
From the comparison in Table 1, it can be seen that the glove prepared in Example 1 to Example 8 of the present disclosure have the functions of moisture absorption, breathability and shielding isolation, it is also wear-resistant and has low bacterial penetration rate and good protection effect. In Example 9, the foam ratio of the moisture wicking layer is too high, In Example 10, the effect is not good because the coating is too thin. It shows that the technical solution of this disclosure has a good effect.
The above is only a specific implementation of the present disclosure, but the scope of protection of the present disclosure is not limited thereto, and any changes or replacements that do not come to mind through creative work shall be covered within the scope of protection of the present disclosure. Therefore, the protection scope of the present disclosure should be determined by the protection scope defined in the claims.
