Description

UV and yellow dust blocking mask < RTI ID = 0.0 >

The present invention relates to a mask for shielding ultraviolet rays and dust, and has a ultraviolet shielding function, and is capable of preventing yellow dust from entering the respiratory tract through a filter and shielding ultraviolet rays and dusts, which are easy to replace filters.

Dust is the phenomenon of fine sand dust blowing up to the sky by the wind spreading in the atmosphere, covering the sky, falling slowly, or falling sand. It is a natural phenomenon that occurred from a very long time ago. Due to global warming and rapid industrialization, Strength is increasing gradually.

The number and intensity of yellow dust occurring in Korea has been increasing rapidly since 1990. The number of days of yellow dust occurrence in Seoul is from 1971 to 1980 on 28, 1981 ~ 1990 on 39, 1991 ~ 2000 on 77 Day, and 122 days from 2001 to 2010. Compared to the 1970s, it has surged more than four times in the 2000s. The strength of the yellow sand is getting stronger. In addition, the former yellow sand was not simply a sand dust, but there was no great danger to health. Recently, air pollution has become worse, and pollution is attached to yellow dust, which is a health risk.

As described above, in order to protect the health of the individual as the number and intensity of the dust increases, the need for a mask to block dust has arisen and a dust mask having improved performance has been developed and is on the market.

Korean Patent Registration No. 0439481 discloses a personal respiratory protection apparatus and a method of manufacturing the same in which a first member (an upper member) and a second member (a lower member) are kept in contact with at least a part of the common surface of the central portion in a face-to- A cup-shaped air chamber which covers the wearer's nose and mouth by the edges of the central part and the union of the first and second members during use is disclosed.

The mask is not comfortable to wear because the unbonded edges of the upper and lower members are in contact and close to the wearer's nose, cheeks and jaws and the outer boundaries of such unbonded edges are shorter than the perimeter of the mask Since the upper and lower members are in face-to-face contact with each other, the structure thereof is severely limited

1 and 2, the present invention relates to a mask for shielding ultraviolet rays and yellow dust, which is composed of a hemispherical filter 200 and a main body 100 in which the filter is embedded.

As shown in FIGS. 1 and 2, the main body includes a front portion 130 on which the earring 110 is formed, a back portion 150 on which the filter 200 is inserted, a nose cover 170 covering the nose, And a bib 190 surrounding the bib 190.

The front portion 130 is made of high density knitted fabric with three deniers and has earrings 110 on both sides thereof.

Wherein the front part is made of a three-denier yarn having a yarn density of about 0.5 to 1 denier of 50 to 80 denier and 60 to 80 filament yarn and having a density of 40 to 48 wpi (wale per inch) and 52 to 60 cpi It would be desirable to knit to a density.

That is, the number of loops per inch in the front part may be 40 to 50 in the wale direction, and 52 to 60 in the course direction.

As described above, the knitted fabric having a high density has a filter function of its own, and has a function of blocking the outside.

The front part 130 is preferably exposed to the outside of the mask to provide an ultraviolet shielding function. The ultraviolet shielding function can be imparted to the front part 130 through a source of ultraviolet shielding function or an ultraviolet shielding function. The ultraviolet ray shielding function can be given through the infrared rays.

As described above, it is preferable that ultraviolet protection factor (UPF) of the front part 130 is 50 to 700.

The front portion 130 may be formed of a polyester-based yarn, a polyamide-based yarn, or a polyol-based yarn, either singly or in combination.

In addition, the front portion 130 may be formed in various colors such as red, blue, green, and black.

1 and 2, the rear portion 150 is formed on the rear surface of the front portion 130 by a method such as a bar method, and the filter 200 is inserted into the rear portion 150 A U-shaped hole is formed.

It is preferable that the U-shaped hole of the back surface portion 150 is formed to be smaller than the filter space into which the filter 200 is inserted so that the filter is not easily released from the U-shaped hole.

The nose cover 170 may be formed on the upper part of the U-shaped hole of the back surface 150 as shown in FIG. 4, which is formed on the front part 130 and covers the nostrils.

As shown in FIG. 4, the nose cover 170 is provided with two cushions 172 having a filler therein so as to press both nostrils, so that external air can be prevented from penetrating into the mask without passing through the filter There will be.

The bib 190 is formed at a lower portion of the front portion 130 to enhance the wearability of the mask and prevent the filter 200 inserted in the rear portion 150 from easily falling.

The filter may be a general filter having two or more fabrics bundled together to have a filtering function. The fabric may be one of a nonwoven fabric, a fabric, and a knitted fabric.

For example, the filter may be composed of an outer layer formed of polypropylene fibers, a filter layer formed of ultrafine polypropylene fibers of 0.1 to 1 denier, and an endothelial layer formed of polyethylene fibers, wherein the outer layer is shielded from large dust, , And the endothelial layer may be formed so as to have a function of maintaining the morphological stability of the filter.

The filter 200 may be formed in the same shape as that of the conventional filter as shown in FIG. 3 (a), but in order to improve the adhesion between the filter and the face, as shown in FIG. 3 (b) And it is preferable that it is formed to be inclined toward the jaw area.

In addition, it is preferable that a portion of the filter 200 contacting the ball is bent so as to be in contact with the bending of the face.

5, the nose cover 170 presses the filter 200 to increase the adhesiveness of the filter 200, and the bib 100 removes the filter from the lower side So that it can be easily worn.

In addition, since the filter 200 has high adhesion with the face, the air that has not passed through the filter is not sucked into the nose or mouth, and thus the efficiency of blocking dust or dust such as yellow dust is excellent.

In addition, the filter 200 is inserted and fixed in the U-shaped hole of the back surface, so that the filter 200 is easy to replace, and the filter is not easily detached even in a large motion.

Hereinafter, embodiments of the mask for blocking ultraviolet rays and yellow sand according to the present invention will be described, but the present invention is not limited to the embodiments.

Example

1 and FIG. 1, a body and a filter having a front part, a back part, a nose lid part, and a bib part were manufactured and a mask for shielding ultraviolet rays and yellow sand according to the present invention was manufactured.

 The main body was made of 100% polyester yarn, and 75 denier / 72 filament polyester yarn was used, and the front and back portions were knitted at a density of 44 wpi (wale per inch) and 56 cpi (course per inch) Respectively.

The filter used was an outer layer formed of polypropylene fiber, a filter layer formed of ultra-fine polypropylene fibers of 0.3 to 0.7 denier, and a triple-layer filter formed of an endothelial layer formed of polyethylene fibers.

◈ Dust mask test and ultraviolet barrier measurement

1. Dust mask conformity test

The mask for shielding ultraviolet rays and dusts according to the present invention manufactured in the above-described embodiment was submitted to the Occupational Safety and Health Agency for the mask test method disclosed in the Guideline for Reference Standards for Dust Prevention and Prevention Masks . The results are shown in Table 1.
