AI Technical Summary

Problems solved by technology

However, the malodorous nature of the mask is a gas, and the chance of contact between the deodorant and the malodorous gas is instantaneous.
Since the non-woven fabric loaded with deodorant is also breathable, there must be malodorous gas passing through without contact with the deodorant in the non-woven fabric. Therefore, a mask that deodorizes the odor to a level that is almost imperceptible has not yet been realized.

Embodiment

[0093] The present invention will be described below using examples, but the present invention is not limited thereto.

[0094] The median diameter of the chemical adsorption type deodorant is measured on a volume basis using a laser diffraction particle size distribution.

[0095] The gas concentration in each deodorization test was measured using a gas detection tube corresponding to each gas.

[0096] The air permeability was measured by the Fraser method specified in JIS L1913:2010. The unit is cm 3 / (cm 2 s). It should be noted that non-woven fabrics made of PP (average fiber diameter 15 μm, weight per unit area 20 g / cm 2 ) air permeability is 220cm 3 / (cm 2 s), rayon non-woven fabric (average fiber diameter 22μm, weight per unit area 25g / cm 2 ) air permeability is 405cm 3 / (cm 2 s), PP-PE blended non-woven fabric composed of PP fiber and PE fiber (average fiber diameter 20μm, weight per unit area 25g / cm 2 ) air permeability is 280cm 3 / (cm 2 s).

reference example 1

[0114] Reference example 1 (production of nonwoven fabric A for deodorization)

[0115] As a chemical adsorption type deodorant for ammonia, zirconium phosphate with a deodorizing capacity of 190mL / g and a deodorizing rate of 2mL / (0.1g·min) for ammonia gas in a standard state was used. The deodorant uses CuO·SiO with a deodorizing capacity of 98mL / g and a deodorizing rate exceeding 0.4mL / (0.1g·min) for hydrogen sulfide gas in a standard state. 2 composite oxides. Then, with the content of zirconium phosphate as 2 parts, CuO·SiO 2 The content of the composite oxide is 6 parts and the content of the solid content of the acrylic emulsion resin is 5 parts by mass, using zirconium phosphate powder, CuO·SiO 2 The composite oxide powder and the acrylic emulsion were used to prepare a deodorant-containing acrylic emulsion A having a solid content concentration of 10% by mass. This deodorant-containing acrylic emulsion A was evenly applied to a nonwoven fabric (average fiber diamete...

[0116] Reference example 2 (manufacture of deodorant nonwoven fabric B)

[0117] As a chemical adsorption deodorant for ammonia, zirconium phosphate with a deodorizing capacity of 190mL / g and a deodorizing rate of 2mL / (0.1g·min) for ammonia gas in a standard state was used. type deodorant, using CuO Al with a deodorizing capacity of 48mL / g and a deodorizing speed exceeding 0.01mL / (0.1g·min) for the standard state of methyl mercaptan gas 2 o 3 ·SiO2 2 composite oxides. Then, with the content of zirconium phosphate as 4 parts, CuO·Al 2 o 3 ·SiO2 2 The content of the composite oxide is 4 parts and the content of the solid content of the acrylic emulsion resin is 3 parts by mass, using zirconium phosphate powder, CuO·Al 2 o 3 ·SiO2 2 The composite oxide powder and the acrylic emulsion were used to prepare a deodorant-containing acrylic emulsion B with a solid content concentration of 10% by mass. This deodorant-containing acrylic emulsion B was evenly applied to a nonwove...

Abstract

This deodorizing mask comprises an air permeable mask main body for covering the nose and mouth of the user with at least two types of nonwoven cloth, the mask main body having a deodorizing nonwoven cloth layer containing a chemical adsorptive deodorizer and a dustproof nonwoven cloth layer having a dustproof effect, and the air permeability of the dustproof nonwoven cloth layer being 2 / 3 or less of the air permeability of the deodorizing nonwoven cloth layer. Preferably, the air permeability of the dustproof nonwoven cloth layer is in a range of 10 to 120 cm3 / (cm2·s) in a permeated air quantity based on the Frazir method, the air permeability of the deodorizing nonwoven cloth layer is in a range of 40 to 400 cm3 / (cm2·s) in a permeated air quantity based on the Frazir method, and the permeated air quantity of the dustproof nonwoven cloth layer is 2 / 3 or less of the permeated air quantity of the deodorizing nonwoven cloth layer.

Description

technical field [0001] The present invention relates to a deodorizing mask having an extremely excellent deodorizing effect against malodors such as excrement odor and putrefaction odor. Background technique [0002] Face masks having various functions such as antibacterial, antiviral, antiallergenic, and deodorizing have been proposed in the past. In particular, there are many proposals for face masks having a deodorizing function using various deodorants. For example, there is a face mask using an activated carbon sheet as a filter (Patent Document 1), a mask containing an absorbent and odor-absorbing sheet of hydrous magnesium silicate clay mineral (Patent Document 2), which will use Fe, Mn, Al, At least one metal selected from Zn and Cu, and a breathable material in which the reaction product of the metal and oxygen-containing polyacids coexist are deodorizing masks (Patent Document 3) and the like that are attached to the mask ventilation part. However, in the case of...
