example 1

[0053] The spunlace nonwoven fabric is prepared from the textile fabric made of bamboo fiber. Gravure coating made 40g / m 2 The allergen deactivator of weight, this allergen deactivator has 20% by weight of chemicals cetyl diphenyl ether disulfonic acid sodium salt on spunlaced nonwoven fabric as active ingredient, the lemon of 2% by weight acid, 2% by weight of polyhexamethylene biguanide and 76% by weight of water. After it dries, an antiallergic treatment is performed. A meltblown nonwoven fabric and a meltblown-spunlaced nonwoven fabric were sequentially laminated on one side of the antiallergic spunlace nonwoven fabric. A 3-layer nonwoven fabric was fused and prepared using ultrasound. The meltblown nonwoven fabric used as the middle layer was a G100 grade corona treated nonwoven fabric.

[0056] The antimicrobial treatment was carried out on the outer layer of the mask body according to performing example 1. PHMB is used as a fungicide.

example 1 and comparative example 1

[0074] Allergens of four types of house dust mite (Der p1, Der f1, Der p2, Der f2), pollen (Bet v1) and pets (Can f1) were used as the respective test allergens. Pollen (Bet v1) and pet (Can f1) allergen protein concentrations were 250 ng / ml. The coverage of the total active ingredient in the sample is set to 1g / m 2 Thereafter, the respective clearing efficiencies of the allergen deactivating agents containing disodium cetyldiphenyl ether disulfonate as an active ingredient were measured. The results are shown in Table 1 below.

[0075] Table 1: Bacteria Reduction

[0076]

[0077] Refer to Table 2 and image 3 It can be understood that when the allergen deactivating agent of the present disclosure is used in Der p1, Der f1, Der p2, Der f2, Bet v1, Can f1, the efficiency of allergen deactivation is much better than that of untreated samples.

Abstract

Provided are a multi-layered nonwoven fabric, comprising: an outer layer formed of a spunlaced nonwoven fabric including at least one of a bamboo fiber and a polyethyleneterephthalate (PET)-based fiber; a middle layer formed of a melt blown nonwoven fabric; and an inner layer formed of a melt blown nonwoven fabric or a melt blown-spunlaced nonwoven fabric, wherein the outer layer comprises an allergen inactivation agent; a method of manufacturing the same; and an anti-allergic product including the same. The multi-layered nonwoven fabric can exhibit good air permeability and weatherability, and even more, can inactivate an allergen and thus exhibit anti-allergic, anti-bacterial and anti-viral effects.

Description

Background technique [0001] Allergy is the response of an organism's defense system to foreign substances (ie, antigens) that invade the organism. In other words, it is an abnormal reaction of the immune system. Generally, when an antigen is invaded, the organism produces antibodies and lymphocytes with specific responses. If the antigen invades again, the organism triggers various immune responses as a self-protecting defense mechanism. This is known as an allergic reaction. [0002] Allergens are antigens that cause allergic reactions. Exemplary allergens include dust mites, pollen, animal hair, skin fragments, plant fibers, bacteria, food, dyes, chemicals. Dust mite secretions can cause allergies when inhaled or directly on the skin. Pollen in the air can enter a person's eyes, nose and lungs and cause allergies. In particular, when pollen gets into a person's nose and neck, this leads to a series of seasonal allergic rhinitis called hay fever. [0003] Pet hair and ...
