In the work process of building a ship, painting work that involves spraying paint or adhesive on the working area of the hull block is essential, and painting workers are inevitably exposed to large amounts of organic solvents.

Here, organic solvents are toxic substances that pollute the environment and contain a large amount of components harmful to the human body (benzene, toluene, etc.), so it is necessary to minimize direct contact or exposure to the skin. To this end, workers must wear various types of protective clothing or protective clothing. Gloves can be worn. Most of the protective equipment is made of latex, vinyl, and rubber and focuses primarily on blocking organic solvents.

However, when working with gloves made of vinyl material that has no heat permeability or skin breathability, the worker's sweat or moisture is not discharged at all, which easily causes skin irritation or eczema, and the large amount of moisture causes hands to slip. There is a problem that workability is significantly reduced.

In addition, in the case of laminated fabrics in which an absorbent material that easily absorbs sweat and a protective material are laminated, the adhesion between the laminated fabrics is low, so even if gloves are commercialized, durability is reduced, such as finger joints or hand wears being easily torn during the wearing process.

As shown in Figures 1 to 4, the method for manufacturing solvent-free inner gloves according to an embodiment of the present invention and the inner gloves using the same have a non-woven absorbent layer 20 as the lining, a film protective layer 40 as the outer material, and an inner glove using the same. Preparing a laminated fabric (10) including an adhesive layer (30) interposed to laminate the nonwoven absorbent layer (20) and the film protective layer (40) (S100); Laminating a pair of laminated fabrics (10), and arranging the linings of the laminated fabrics (10) to face each other (S200); And it may include a step (S300) of ultrasonic welding the edge of the laminated fabric 10.

The step of preparing the laminated fabric 10 can be performed (S100).

The laminated fabric 10 includes a non-woven absorbent layer 20 as a lining, a film protective layer 40 as an outer fabric, and an adhesive layer 30 interposed between the non-woven absorbent layer 20 and the film protective layer 40. can do.

A non-woven absorbent layer 20 may be provided on the lining, which is the part that directly contacts the worker's skin. Here, the non-woven absorbent layer 20 is generated from the skin. In terms of sweat or moisture absorption, the non-woven absorbent layer 20 may have a relatively high moisture content for sweat or moisture compared to existing vinyl, and a large amount of breathability can be secured. .

And the film protective layer 40, which is the outer layer, is a part that blocks internal intrusion of organic solvents from the outside, and breathability must be secured compared to existing vinyl.

For this purpose, CaCO3-based powder particles may be added to the film protective layer 40. CaCO3 series can mainly target stone dust, lime powder, etc.

The non-woven absorbent layer 20 may be made of polypropylene, the film protective layer 40 may be made of polyethylene film, and the adhesive layer 30 may be made of polyurethane.

For example, the film protective layer 40 made of polyethylene may have a thickness of about 20.0 to 80.0 (micron meters), and the non-woven absorbent layer 20 made of polypropylene may have a thickness of 120 to 250 (micron meters). In addition, the particle size of the CaCO3-based powder particles added to the film protective layer 40 may be 0.1 to 1 (micron meter).

A test example of this laminated fabric 10 may be accompanied.

It was conducted at the Korea Apparel Testing & Research Institute, and artificial blood penetration resistance tests, chemical solution penetration resistance tests, and various microbial penetration resistance tests were performed.

Looking specifically, in the case of the artificial blood penetration resistance test, the test results of STEP6 were confirmed in all three tests. Here, STEP6 means raising the pressure at a rate of 3.5 kPa/s or less and maintaining 20 kPa for 5 minutes.

Chemical solution penetration resistance (%) KS K ISO 6530:2005 Permeability index (P) 0.0 Absorption index (A) 3.6 Water repellency index (R) 94.1

Next, the chemical solution penetration resistance was confirmed as permeability index (P) of 0, absorption index (A) of 3.6, and water repellency index (R) of 94.1.

Here, the amount of reagent introduced is 10ml, and the reagent introduction speed is 1ml/s.

Penetration resistance (water repellency index) = (weight of test solution collected in beaker/weight of test solution supplied to test piece).

As can be seen in Table 1, the permeability index was 0 and the water repellency index was confirmed to be over 94%, confirming permeation resistance to chemical solutions (organic solvents).

Next, a wet bacterial penetration resistance test (EN 14126:2003) was performed.

RESISTANCE TO MICROBIAL PENETRATION- WET Test results One 2 3 4 5 test time/(CFU) 30min 0 0 0 0 0 60min 0 0 0 0 0 Donor 106 100 95 64 89 barrier index. IB individual 6.00 6.00 6.00 6.00 6.00 mean 6.00 result Class 6

Here, Class 6 refers to the case where breakthrough time (min) t > 75 or more.

As a result, the laminated fabric (10) passed the artificial blood penetration resistance test STEP6, the water repellency index was confirmed to be over 94%, and penetration resistance to chemical solutions (organic solvents) was confirmed, and the wet bacterial penetration resistance test was also Class Class. Confirmed as 6.

Accordingly, a protective function is secured through the laminated fabric 10, which is laminated with a non-woven absorbent layer 20 that ensures skin breathability and a film protective layer 40, while simultaneously blocking organic solvents and making it relatively easy to discharge sweat or moisture. You can.

In addition, due to the CaCO3-based powder particles in the film protective layer 40, it was confirmed that the breathability of the film protective layer 40 at the molecular level was relatively increased compared to existing vinyl.

Next, a step of arranging a pair of laminated fabrics 10 may be performed (S200).

At this time, referring mainly to FIG. 2, a pair of laminated fabrics 10 may be stacked, and the linings of the laminated fabrics 10 may be arranged to face each other.

Next, a step of ultrasonic welding the edges of the laminated fabric 10 may be performed (S300).

The ultrasonic welding step (S300) is performed with a welding roller (GRAVURE ROLLER, not shown), and a pair of laminated fabrics 10 are joined using a protruding section (not shown) corresponding to the shape of the inner armor provided on the welding roller. You can do it. The protruding section is the edge area of the inner armor, so that an ultrasonic fusion section 300 can be created. At this time, the operating speed of the welding roller is 80-150 meters/min, and the welding work can be performed at a casting temperature of up to 280℃.

Accordingly, an ultrasonic fusion section 300 can be provided as shown in FIGS. 3 and 4. The ultrasonic welding section 300 is formed at regular intervals along the edge area of the inner glove excluding the hand inlet side of the inner glove (lower part of the glove in Figure 3), and as the welding process is performed at a relatively high temperature, the laminated fabric (10 ) Mutual adhesion can be secured.

On the other hand, even when inner gloves are commercialized due to the lack of adhesion between the laminated fabrics 10, there is a problem in that durability is reduced, such as finger joints or hand wear parts being easily torn during the wearing process.

Accordingly, in this embodiment, the step of forming the first and second joint reinforcement sections 410 and 420 at the edges of the product shape may be performed simultaneously with this fusion process (S400).

As shown in (a) of FIG. 4, the first joint reinforcement section 410 may be provided adjacent to the hand worn device. Accordingly, tearing can be prevented when the worker puts his hand into the inner glove.

Additionally, the second joint reinforcement section 420 may be provided in the finger joint section. The second joint reinforcement section 420 is provided in a distorted oval shape to correspond to the shape of the connection portion of the seam, and the rigidity of the ultrasonic fusion section 300 can be reinforced.

The first and second joint reinforcement sections 410 and 420 may be performed simultaneously with the welding process of the ultrasonic fusion section 300 and may be formed by a protruding section added to the fusion roller.

According to this step configuration, skin breathability and protective functions can be secured through the laminated fabric 10, which is laminated with the non-woven absorbent layer 20 and the film protective layer 40, which ensure skin breathability, thereby blocking organic solvents and preventing sweat or moisture at the same time. Moisture discharge is relatively easy, which can improve the worker's workability, and the laminated fabrics (10) are bonded to each other using an ultrasonic fusion technique, and a plurality of adhesive reinforcement parts (410, 420) are placed on the vulnerable parts of the product to ensure durability even during the wearing process. It can be maintained.

On the other hand, the solvent-free inner glove manufactured by this manufacturing method has a non-woven absorbent layer 20 as the lining, a film protective layer 40 as the outer material, and the non-woven absorbent layer 20 and the film protective layer 40 interposed between them. An inner body of a glove (not shown) and an outer body of a glove (200) made of laminated fabric 10 including an adhesive layer 30 to be laminated; An ultrasonic fusion section 300 that joins the edges of the inner armor body and the outer armor body 200; And it may include a first joint reinforcement section 410 provided on the entrance side of the glove, and a second joint reinforcement section 420 provided between the fingers of the glove.

The ultrasonic fusion section 300 and the first and second joint reinforcement sections 410 and 420 may have an elliptical joint shape.

Through the inner gloves of this configuration, skin breathability and protective function can be secured through the laminated fabric (10) laminated with the non-woven absorbent layer (20), which ensures skin breathability, and the film protective layer (40), thereby blocking organic solvents at the same time. It is relatively easy to release sweat or moisture, which can improve the worker's workability, and by bonding the laminated fabrics (10) to each other using an ultrasonic fusion technique and placing a plurality of adhesive reinforcements on vulnerable parts of the product, durability can be maintained even during the wearing process. .
