Description

MANUFACTURING METHOD OF COATING GLOVES}

The present invention relates to a method of manufacturing a coated glove comprising a palm portion and a finger portion of the glove as a coating surface. More specifically, the coating of the palm portion and the finger portion of the glove is performed in an in-line process quickly and simply with high quality. The present invention relates to a method for producing coated gloves capable of producing a large amount of coated gloves having a coated surface.

Gloves worn to protect hands or to prevent contamination of hands that come into contact with workpieces are generally made of cotton yarns, polyester yarns, nylon yarns, or aramid yarns, depending on the purpose and function of use.

The glove thus prepared is not suitable for handling slippery objects, and thus the glove surface is prepared by reprocessing the surface of the glove with a coating such as rubber having a high coefficient of friction.

Rubber coated gloves are manufactured by forming a rubber coating layer on the surface of the gloves by impregnating the gloves in the coating solution and then taken out and dried.

As the coating liquid used for rubber coating on the glove surface, a coating liquid obtained by mixing natural rubber and acrylonitrile butadiene rubber is generally used. In general, in the case of rubber coating on the surface of the glove, as the rubber coating liquid penetrates deep into the glove and hardens, not only the fit is reduced but also the breathability is not absorbed by the glove due to poor breathability.

Various manufacturing methods have been proposed to supplement the breathability of rubber coated gloves. Republic of Korea Patent No. 476099 discloses a technique of foaming the coating solution, and then impregnated gloves with the foamed coating solution for a certain time and then taken out to dry. Specifically, NBR, crosslinking agent, dispersing agent, emulsifying stabilizer, ammonia water, alkaline aqueous solution, foaming agent, thickener, vulcanization accelerator, and water. Technology.

Rubber coated gloves prepared using the foamed coating composition showed excellent permeability and improved fit, but the surface was smooth and the sliding performance was not significantly improved.

In order to improve the sliding performance, a technique of coating the surface of the glove has been proposed. Republic of Korea Patent No. 346651 discloses a rubber coating solution in which rubber, sulfur oxide, and accelerator are added to natural rubber, impregnated with a glove with calcium chloride solution sprayed, and then dried and soaked with a rubber coated glove in an organic solvent. Shrink the rubber liquid to form a pattern, and then dried and dried gloves in a neutralizing solution, and then washed and dried to produce a rubber coated glove treating the surface with a rubber layer.

The wet manufacturing method is a coagulant that is compatible with DMF (Dimethyl formamide), an organic solvent used for dissolving polyurethane and coating oil-based wet resin on the glove endothelium. The organic solvent present in the polyurethane coating layer is passed through the coagulation bath to diffuse into the coagulation solution in the coagulation bath to form fine pores therein through the coagulation process of the resin to impart breathability.

Gloves manufactured by the oil-based wet manufacturing method are excellent in moisture permeability and fit, but have weaknesses due to fine porosity, weak durability, and yellowing during long-term storage.

A method for producing coated gloves using aqueous polyurethanes has been studied. Glove manufacturing method using the water-based polyurethane is a dry method of drying the coating by preventing the resin from entering the endothelial during the pretreatment of the coagulant or water repellent on the glove endothelium and coating liquid impregnation.

The dry manufacturing method has the advantage of using environmentally friendly water-based resins, but the coating layer of the glove is a film or a high density, so that the moisture permeability and breathability is low or weak, and it is possible at the laboratory level. It is difficult to expect formation.

In order to secure moisture permeability in a dry manufacturing method using an aqueous polyurethane, a method using a mechanical foam and a chemical foaming agent has been proposed.

Since it is a dry manufacturing method, first, pretreatment of coagulant or water repellent is applied to the endothelial glove and mechanical foam or chemical blowing agent is used to secure moisture permeability.

The dry method by mechanical foaming forms bubbles by simple high speed agitation or by using a mechanical foaming machine, so that the uniformity and fineness of the pores are inferior to the wet chemical porous forming method. As a result, the moisture permeability and wear resistance are bad, and it is also difficult to prevent penetration by a pretreatment and to form a uniform coating surface.

Another method of forming a pore using a chemical blowing agent is to form pores using a boiling point when drying by adding a large amount of a low boiling point solvent to an aqueous resin, or to form pores using a blowing agent that decomposes at a high temperature to generate a gas. There is a way. Since these methods use organic solvents or blowing agents harmful to the human body, there is room for environmental pollution, and it is difficult to secure formation and uniformity of micropores.

Due to this, there is a problem in that the dry manufacturing method using the water-based polyurethane cannot replace the conventional oil-based wet gloves with stability such as breathability, moisture permeability, wear resistance, and soft fit.

In general, a glove has a structure in which a finger-fitting part that can put a finger, a hand-fitting part that can put a hand, and a wrist contact part in contact with the wrist are integrally provided.

FIG. 1 is a view for explaining a type of general coating gloves manufacturing process for manufacturing coated gloves, in which a glove template 10 is immersed in a polymer coagulant coating composition 11 immersed in a water tank 12, and the coating is made of gloves 13 Is a schematic diagram of an inline process in which the polymer coagulant coating layer 14 is adhered to the glove template 10 surface until it is adhered thereto.

Figure 2 is a process flow chart showing a specific coating gloves manufacturing process of the prior art. General coating gloves manufacturing process is produced through each process divided into roughly impregnation, coating, fixing, washing, drying, curing.

In the impregnation process, the coagulant solution is impregnated into the glove endothelium, but the glove endothelium is immersed in the coagulant solution, vacuum degassed and compressed to impregnate the coagulant solution into the glove endothelium.

In the coating process, the endothelial impregnated with the flocculant solution is mounted on the glove mold, and then immersed in the coating solution for 1 to 15 seconds to coat the glove surface with an aqueous polyurethane coating solution.

The fixing process is a process of naturally fixing an aqueous polyurethane coating solution to an armored endothelial by naturally drying a polyurethane coated liquid coated endothelial at room temperature to generate a phase transition between the flocculant solution impregnated with the endothelial shell and an aqueous polyurethane coating solution.

The washing process is a process of washing the solution with the coagulation remaining on the glove endothelium.

The drying process is a process of drying the glove endothelium from which the remaining coagulant solution is removed at 75 to 90 ° C.

The curing process is a process of curing the glove endothelium dried through a drying process at 120-140 ° C. for 15-25 minutes.

Latex coated gloves, on the other hand, incorporate water soluble particles into the uncured latex layer. Latex coated gloves are obtained, for example, by adhering and solidifying a solid granular material on a non-solidifying resin emulsion latex.

The latex composition coating is formed on the surface of the mold. In the state where the latex coating becomes non-solid, particles which do not dissolve in the latex but dissolve in the water solution, such as salts, are sprayed and adhered onto the latex coating.

After the coating is vulcanized, the salt is removed by washing with water to obtain a rubber glove made of an air impermeable and water impermeable rubber skin with fine depressions or protrusions on its surface. Since the latex is fluid before vulcanization, the incorporated particles are covered by the latex.

Stirring is required to suspend the hydrophilic solid in a latex solvent solution. When the template is immersed in this latex solvent solution, this sedimentation behavior may not result in a uniform distribution of hydrophilic solids.

Conventional latex coated gloves made by conventional latex inline dipping processes require complete control of the size and shape of the latex surface coating features and coating distribution. There is a need for a reliable process for the generation of coated glove surfaces.

As described above, according to the conventional manufacturing method of coated gloves using a material of synthetic rubber (NBR) and natural latex, it is difficult to effectively expect a coating on a specific part of the gloves. For example, when a limited coating of the palm (including the back of the hand) and the finger portion of the glove is required, there is a problem in that a systematic coating cannot be performed.

In the case of gloves used for using the palm and finger parts of gloves, it is sometimes effective to form a partial coating surface in wearability, breathability, moisture permeability, etc. rather than the entire coating on the entire surface.

Partial coating of gloves can reduce the amount of coating material used compared to the whole coating, reduce the emission of pollutants and reduce the manufacturing cost, can be produced economically. However, there is a problem that mass production is difficult and quality control is difficult.

The present invention has been made to solve the problems of the prior art to quickly process the partial coating on the fingertips and palm parts of the gloves in the production of coated gloves by coating the gloves with synthetic rubber, latex, in-line process An object of the present invention is to provide a coated glove manufacturing method including a palm portion and a finger portion as a coating surface.

The present invention is a smooth mold 200 that can be fitted by mounting the glove 100 to form a coating surface having a geometrically defined surface structure on the finger and hand 110 of the woven glove 100 as shown in FIG. ) Using a facility material that can be fixed or attached through some structure 210 to attach or detach the glove 100 along the mold 200 when needed.

In addition, a water tank 310 that can contain the coating agent 300, and a lifting mechanism for lifting the water tank 310, a movement mechanism for lowering the mold 200 in the water tank 310 may be included. . 3 shows an example in which the water tank 310 is lifted in the direction of the arrow, but all of the fingers 110 and the fingertips of the finger 110 of the glove 100 are immersed in the coating material 300 contained in the water tank 310. These devices are prepared to form a coating surface 120 on the finger portion and palm portion of the glove 100.

The coated surface 120 is made of a NBR (synthetic rubber) composition or formed of a natural latex resin composition, and the present invention is to produce a coated glove having such coated surface 120.

Dipping the prepared gloves into a polymer coagulant for coating the gloves on a woven or other method, and for this purpose, the coagulation particles are separated from the various processes in which the gloves are molded into a smooth mold template and immersed in the polymer coagulant. The grip can vary in size, shape and distribution, and the grip performance will vary.

Method for producing a coated glove comprising the finger portion and palm portion of the glove according to the present invention as a coating surface is prepared through an in-line process as shown in FIGS.

The main process is, first of all, the manufacture of gloves. The glove is manufactured by selecting any one or more materials selected from cotton yarn, polyester yarn, nylon yarn, and aramid yarn. Glove 100 includes a woven or any other manufacturing method that can complete the shape of the glove (S101).

Then, it is a wearing step of mounting the gloves to the mold by inserting the prepared gloves to spread the prepared gloves evenly. (S102)

Then, the first coating step of pre-treating the coagulant evenly penetrates the entire palm and fingers of the glove by impregnating the glove 100 mounted on the mold 200 in the coagulation solution or water repellent from the wearing step.

And, the semi-drying step of drying the coated gloves from the first coating step in a semi-dry state. (S104)

And a second step of treating the semi-dried gloves through the semi-drying step so that the tank is raised to the finger and palm portions of the gloves so that the coating material is impregnated and coated on the fingers and the palms of the gloves so as to be impregnated in the tank containing the coating agent. Coating step. (S105)

When the coating on the finger and palm portion of the glove is completed through the second coating step, the surface is sprayed with sodium chloride on the corresponding surface of the coated surface, sprayed with an antifoaming agent on the surface, and blown off by spraying air on the surface. (S106)

In addition, the coated gloves having been subjected to the surface treatment step are obtained in a water tank, and a residual material decomposition step of decomposing and removing residual coagulant, water repellent, and coating agent remaining in the glove (S107).

Then, the gloves are removed from the mold through the residual material decomposition step (S108) to the product inspection and packaging step (S109).

In addition, the coating agent 300 may selectively use any one selected from NBR, natural latex.

In addition, it is possible to accelerate the solidification rate of the coagulant by setting the pre-temperature of the mold 200 used to wear the glove 200 to the mold 200 in the range of 45 ~ 60 ℃.

In the residual material decomposition step, in order to decompose the residual material remaining in the glove 100 through the decomposed water contained in the tank, at least one tank containing water of 30 ° C. is disposed and at least one glove is obtained in each tank. 10 to 15 minutes of decomposing time to adjust the total residue decomposition time in the water tank can be decomposed residues by 30 to 45 minutes.

In addition, the drying material may further include a drying step of drying through a tunnel-type dryer controlled at a temperature atmosphere of 110 ~ 130 ℃ to dry-cure the coating glove 100 in a state in which the residual material is decomposed through the residual material decomposition step. .

Reference numerals showing the NBR coating and the natural latex coating herein are mixed and described as '300', respectively.

The manufacturing method of the coated glove including the palm part and the finger part according to the embodiment of the present invention as a coating surface will be described in detail with reference to FIGS. 3 to 6.

For reference, the NBR coating 300 and the natural latex coating 300 is a coating material whose function is generally used to manufacture coated gloves.

Embodiment of the present invention relates to a method of manufacturing a coated glove coating NBR or natural latex on the fingers and fingertips of the glove.

The manufacturing method is a difference between the composition of the composition forming the coating surface 120, that is, the NBR coating agent and the natural latex, the overall manufacturing process of the coating gloves for coating is different in temperature atmosphere and curing and drying time. Thus, the production method presented in the examples is described as a unified production process regardless of the choice of materials to be used.

5 is a process chart of the coating glove including a palm portion and a finger portion as a coating surface according to an embodiment of the present invention.

First coating step by coagulant ( S103 )

Coagulant coating is the first coating step. In the first coating step for the coagulant coating it is possible to use separate coagulant particles which are water soluble, partially water soluble or water insoluble. The separate coagulant particles may be coated by a dry powder coating process onto a tacky, water soluble polymer coagulant coating or film.

Semi-drying step ( S104 )

Drying the coated gloves from the first coating step in a semi-dry state. Complete drying makes it difficult to impregnate with the coating.

NBR / Natural Latex Coating (Liquid) Related

The geometric coating surface 120 created on the glove outer surface provides the glove's ability to hold the tools and devices under dry, wet and oily environments.

The degree of traction or grip force provided by the outer surface coating structure of the glove having the coating surface 120 may be selected in a controlled manner by selecting the particle size of the separate coating particles used. The separate coating particles in the range of about 50 to 200 microns in size allow for smoother traction than the separate coagulant particles in the range of about 150 to 2,000 microns in size.

As the NBR or natural latex water soluble polymer coating solution, a polymer selected from the group consisting of PVP, PVA, PAA, PAC, and / or copolymers or derivatives of PVP, PVA, PAA or PAC can be used.

Examples of copolymers are copolymers of 1-vinyl-2-pyrrolidone and 1-methyl-3-vinyl-imidazolium-methylsulfate, and vinylcaprolactam / vinylpyrrolidone / dimethylaminoethyl methacrylate Of copolymers. Polyacrylic acid includes a range of water soluble acrylic homopolymers and / or methacrylic acid homopolymers. PVP or PVP copolymers and PACs are commonly used as main components in hairstyling products.

The polymer or copolymer thereof is a separate coating particle that is water soluble, partially water soluble or water insoluble in the finger and palm 110 regions of the glove 100 prior to being immersed in the glove with NBR (synthetic rubber) or an aqueous natural latex emulsion. Keep it at

The amount of water soluble polymer incorporated into the polymer coating coating can vary from 0.01 to 10 dry weight percent. Ideally, the level should be in the range of 0.5% to 1.5% to provide sufficient adhesion to maintain separate coating particles on the glove surface.

The water soluble discrete coating 300 particles may be selected from the group comprising all kinds of dry salts. Examples of suitable salts for the separate coating particles include sodium chloride, potassium chloride, calcium nitrate, calcium chloride and aluminum sulfate.

It is preferred to use water soluble discrete coating particles embedded in the coating of the polymer coating 300, but water insoluble discrete particles that are applied through a dry powder coating process and then washed away using an acid wash instead of a water wash, for example It is possible to use calcium carbonate or sodium bicarbonate. Dry coating application of separate coating particles can be carried out using standard techniques commonly used in the industry, such as sparging systems, pressurized spraying and atomizing and fluidizing air layers. In the present invention, the coating agent 300 is accommodated in the water tank 310, and the finger and hand palm 110 of the glove 100 are impregnated in the coating material 300 contained in the water tank 310 to locally coat the coating surface 120. It is an example of getting.

As the coating agent 300, NBR / natural latex coating solution may be used in the following composition.

The NBR coating agent 300 may be a mixture of liquid compositions including NBR, a crosslinking agent, a dispersant, an emulsion stabilizer, ammonia water, an alkaline aqueous solution, a foaming agent, a thickener, a vulcanization accelerator, and water.

Similarly, the natural latex coating agent 300 may be a mixture of a water-soluble natural latex, a crosslinking agent, a dispersant, an emulsion stabilizer, ammonia water, an alkaline aqueous solution, a foaming agent, a thickener, a vulcanization accelerator, and water.

In addition, each NBR / natural latex coating agent 300 may be used by basically using the following additives or excluding these mixed additives, or by adding and substituting or mixing.

0.1 to 5 parts by weight of water repellent

In general, the use of a water repellent in the coating composition as an additive in the production of coated gloves can improve the water repellency, fouling resistance and water resistance after manufacturing gloves. As the water repellent, a fluorine compound or a silicon compound may be used.

If the water repellent is used less than 0.1 parts by weight, there may be a problem that the water resistance and water repellent effect of the glove product is lowered, and when used in excess of 5 parts by weight may cause undesirable effects on the mechanical properties, feel and appearance of synthetic leather There may be a problem.

0.1 to 6 parts by weight of dispersant

Anionic emulsifiers or nonionic emulsifiers may be used as the dispersant, preferably sodium bis (2-ethylhexyl) sulfosuccinate, sodium lauryl sulfate, sodium isopropyl naphthalenesulfonate, sodium bis (tridecyl) sulphate Posuccinate, disodium lauryl ether sulfosuccinate, N-octadecyl disodium sulfosuccinate, ammonium stearate, octylphenoxy

Cypoly (ethyleneoxy) ethanol, trimethylnonyloxy poly (ethyleneoxy) ethanol, nonylphenoxy poly (ethyleneoxy) ethanol, glyceryl trioleate, ethylene glycol ethylene monostearate, sorbitan trioleate, sorbitan tree Stearates or those selected from the group consisting of two or more of these may be used. The dispersant has a function of increasing the stability of the coating liquid and helping to form a coating film of the coating layer.

Defoamer 0.1 to 3 parts by weight

As the antifoaming agent, silicone and non-silicone type may be used.

It is to be understood that the antifoaming agents are well known to those skilled in the art so that they can be easily purchased and used commercially. Defoamers deflate and deflate bubbles, in particular bubbles in a dispersion coated on the surface of the glove, to remove bubbles and pinholes of several tens of microns or more in the coating surface of the final obtained glove.

If the antifoaming agent is used in less than 0.1 parts by weight, deterioration of the antifoaming action will cause bubbles and pinholes, which are a problem in quality in the coating layer and on the surface, on the contrary, if it exceeds 3 parts by weight, the mechanical properties of the obtained gloves can be reduced. Also, stains may occur on the glove surface.

0-5 parts by weight of colorant

As the colorant, a commercially available colorant made of a non-silicone-based dispersant may be used. The colorant may be used without white, and may be used up to 5 parts by weight in some cases when hiding power is required due to the color of the inner skin.

0.1-3 parts by weight of viscosity regulator

Viscosity modifiers may be used up to 0.1 to 3 parts by weight, depending on the solids content of the mixed solution, preferably may be adjusted to 200 to 1,500cps, more preferably 300 to 900cps before use. Acrylic, cellulose, or urethane may be used as a commercially available viscosity modifier.

Other resin

The coating solution mixture obtained by mixing the additives may be used alone, but if necessary, a mixed solution such as acrylic resin and polyester resin may be added in an amount of 0 to 100 parts by weight for economical or mechanical properties. Crosslinking agents, such as a sleepy, a melamine, an aziridine system, can be added and used at 0-15 weight part.

The solids of the mixed solution and the crosslinking agent to be mixed may preferably be used at 12 to 30% by weight. In the general coating liquid viscosity, if the solid content is less than 12%, the formation of the coating layer is insufficient, the coating purpose as a coating glove is lost, the mechanical properties such as tensile strength and abrasion resistance may be lowered, if the solid content exceeds 30%, The moisture permeability and soft fit of gloves can be reduced.

Second coating step ( S105 )

As a general dipping coating method of the glove, the mold 200 equipped with the glove endothelium woven from nylon, polyester, polyethylene, kevlar and cotton is impregnated with the coating liquid for 1 to 15 seconds. .

In the second coating step (S105) according to the present invention, the coating solution is impregnated to the extent that the coating solution can completely penetrate the inner surface of the finger portion and palm of the glove 100.

By forming a coating surface 120 on the finger portion and the hand 110 of the glove 100 through this to improve the adhesion of the finger portion and the hand portion of the glove by sliding the finger portion and hand portion of the glove Prevents losing

In general, the finger and palm parts of the glove are likely to slip when in contact with the object, and the immersion phenomenon is large and the fit is poor. However, in the present invention, since the coating liquid penetrates deep into the inner surface of the finger portion of the glove and the inner skin of the fingertip, the adhesiveness between the hand and the glove is improved when the glove is worn, and the glove slips from the hand.

In addition, the coating step may include a process of treating the balance after the coating.

This balance treatment is for achieving a uniform coating. As the mold 200 moves, it may be made through vertical movement and rotation of the finger portion and the palm portion of the glove. Coating techniques can be easily understood and practiced by those skilled in the art.

Looking at the second coating step (S105) in more detail may optionally include a solidification step. Solidification treatment by the use of coagulants is a commonly practiced technique.

The coagulation step can be achieved by immersing the impregnated coated glove in a coagulation bath containing the coagulating solution.

As the coagulating liquid, various acid aqueous solutions, aqueous salt solutions, aqueous base solutions or a mixture of two or more of them can be selected and used.

Aqueous solutions of acids include acids such as hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, hydrogen bromide, hydrogen iodide, nitrous acid, hypochloric acid, hydrofluoric acid, hydrogen sulfide, carbonate, sodium carbonate, gluconic acid, citric acid, malic acid, acetic acid, formic acid, propionic acid, and the like. Salt solutions include sodium chloride, potassium chloride, calcium chloride, silver chloride, copper chloride, mercury chloride, ammonium chloride, silver bromide, ammonium bromide, silver iodide, barium carbonate, calcium carbonate, magnesium carbonate, sodium carbonate, silver nitrate, copper sulfate, sodium sulfate, sulfate Calcium, ammonium sulfate, etc. may be included, and the aqueous base solution may include sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, ammonia, triethylamine, aminomethylpropanol, and the like, and may also include a mixture of two or more of them. . Appropriate coagulation liquid may be used depending on the type of hydrophilic group of the coating liquid.

In the method of using the coagulating solution, the concentration of the coagulating solution may be preferably 1 to 35% by weight, more preferably 5 to 25% by weight, and when the concentration of the coagulating solution is less than 5% by weight, When obtained into the coagulation solution, the coating solution may be loosened and the micropores may be formed during drying due to the lack of coagulation. On the contrary, when the coagulation solution exceeds 25% by weight, a problem with washing may occur.

Surface treatment steps ( S106 )

When the coating on the finger and palm part of the glove is completed through the second coating step, the surface of the coating surface is sprayed with sodium chloride while spraying an antifoaming agent on the surface, and spraying air on the surface to shake off the surface.

The spraying of sodium chloride causes the particles to stick to the coating surface, thereby hardening the tissue and curing the coating solution.

By spraying the antifoaming agent, the coated surface is treated with the embossed surface instead of the smooth surface due to the microstructure structure, thereby enabling the gloves to functionally increase adhesion, friction, and traction between the finger and palm.

Air is sprayed onto the coating surface to remove the fine grain particles generated during the surface treatment to obtain a relatively stable and clean surface structure.

Residual material decomposition step and drying step S107 )

A coated glove with a coated surface on the fingertips and fingertips is obtained in a water bath to decompose and remove residual coagulants and water repellents and NBR / natural latex coatings remaining in the glove.

Here, in order to decompose the residual material remaining in the glove through the decomposed water contained in the tank, at least one tank containing water of 30 ° C. is placed in at least one tank and the gloves are obtained in each tank for 10 to 15 minutes of decomposition time. It is preferable to decompose the residual material by adjusting the total residue decomposition time in the water tank between 30 to 45 minutes by passing through.

When the disassembly cleaning and drying is completed, the gloves are demolded from the mold 200 (S108), and the inspection and packaging (S109) to prepare the coated gloves 100 having a coating surface 120 on the finger portion and palm 110 portion. Is completed.

6 (a) (b) is a real product picture of a coated glove including a palm portion and a finger portion manufactured according to an embodiment of the present invention as a coating surface on the finger portion and palm 110 of the glove 100 It can be seen that a uniform coating surface 120 is formed with an even distribution.

Hereinafter, embodiments of the present invention will be described in detail. The embodiments are provided to illustrate the present invention, and do not limit the present invention to the embodiments.

Example  One

A coating solution was prepared at the composition ratio shown in the following [Table 1].

Coating agent ingredient Content (parts by weight) Coating liquid Aqueous dispersion 100 Water repellent Fluorine Repellent 2.0 Dispersant Disodium lauryl ether sulfosuccinate 3.0 coloring agent Toner, solids 3.0 Antifoam Non-silicone type 1.0 Viscosity Modifier Urethane 2.0 NBR Synthetic rubber 50 water Purified water 38

After degassing the coating solution in which the solid content is mixed with 20% by weight of the composition ratio, the impregnated coating of the mold 200 equipped with the inner glove 100 made of nylon with the coagulant is made into a coagulant to make a penetration coating, and then 10 wt. Impregnated and solidified with a coagulation bath made of% aqueous solution of gluconic acid, washed with water for 10 minutes, dehydrated and semi-dried, and then partially coated by impregnating the finger and fingertips of the gloves with the coating solution. Gloves were obtained by recovering the gloves from the mold by disassembling for 45 minutes and drying and demolding the gloves through a tunnel-type drier controlled at a temperature atmosphere of 110 to 130 ° C.

The real product which photographed the obtained glove with the digital camera is shown in FIG. As shown in Figure 6 it can be seen that the NBR resin penetrated into the finger portion and finger portion of the glove to form a coating surface (120). Coating surface 120 is formed uniformly on the finger portion and the palm portion. The coating surface 120 formed as described above is excellent in moisture permeability, wear resistance, and adhesiveness, and it can be confirmed that the demolding workability of recovering the coated gloves from the mold is also free.

Example  2

A coating solution was prepared at the composition ratio shown in the following [Table 2].

Coating agent ingredient Content (parts by weight) Coating liquid 100 Water repellent Fluorine Repellent 2.0 Dispersant Disodium lauryl ether sulfosuccinate 3.0 coloring agent Toner, solids 3.0 Antifoam Non-silicone type 1.0 Viscosity Modifier Urethane 2.0 LATEX Natural ingredients 50 water Purified water 38

[Table 2] After degassing the coating liquid mixed with 20% by weight of the solid content in the composition ratio, the impregnated coating of the mold 200 equipped with nylon woven glove 100 endothelial coated with a coagulant to make a penetration coating 10 weight Impregnated and solidified with a coagulation bath made of% aqueous solution of gluconic acid, washed with water for 10 minutes, dehydrated and semi-dried, and then partially coated by impregnating the finger and fingertips of the gloves with the coating solution. Gloves were obtained by recovering the gloves from the mold by disassembling for 45 minutes and drying and demolding the gloves through a tunnel-type drier controlled at a temperature atmosphere of 110 to 130 ° C.

The glove thus obtained penetrated and solidified the natural LATEX resin in the finger portion and the palm portion to form a coated surface 120. Coating surface 120 is formed uniformly on the finger portion and the palm portion. The coating surface 120 formed as described above was excellent in moisture permeability, abrasion resistance, and adhesiveness, and was also free of demolding workability to recover the coated gloves from the mold.

As described above, the present invention has been described with reference to the drawings and specification, with reference to an embodiment of the invention, but it is an example. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention.
