Description of the invention (f) [Scope of the invention] The present invention is a "multi-fiber laminated activated carbon filter material", especially a kind of two-component fiber added to ultrafine fiber and The new structure between activated carbon materials can utilize the outer structure of the low melting point of the two-component fiber to achieve the purpose of tightly bonding the ultrafine fibers with the activated carbon material, and at the same time dissolve the space occupied by the ultrafine fibers. Allow the air circulation channel to reduce the pressure loss greatly. [Conventional background] Conventional activated carbon filter material, such as the mask structure of US Pat. No. 3,973,173, as shown in the first figure, is a melt blown material 11 (melt blown) and activated carbon material 12 (activated carbon) is mixed 13 Then, the vacuum collector 14 is used to form a mesh 15 of an appropriate thickness, and then a mask or filter cotton is formed. This traditional method has been used for a long time, but in actual use, it has been found that the cotton structure often has the phenomenon of separation and shedding after use, and it has restrictions such as large pressure loss and thickness that is not easy to change. In view of this, the inventor Special research and development improvement cost case, we can borrow this case to provide a more ideal filter cotton. [Objective of the Invention] This case was printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The purpose of this case is to provide a "multi-fiber laminated activated carbon filter material". The component fiber, by using its characteristics, can provide the effect of bonding the old raw material materials to increase the structural adhesion of the activated carbon filter cotton body. At the same time, it can be used for superfine fibers. Paper size applies to China National Cricket (CMS) / V4 specifications (21 × 297 mm) 496755 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Invention Description (>) The space occupied by the dimensions has melted away, and Give up the air circulation channel to achieve the purpose of greatly reducing the pressure loss. [Example] With regard to the structure and composition of the "multi-fiber laminated activated carbon filter material" of the present invention and the effect produced by it, with reference to the drawings, a detailed description of a preferred embodiment of this case is as follows: As shown in the two figures, the "multi-fiber laminated activated carbon filter material" in this case includes ultrafine fibers 21 (melt blown) and activated carbon 22 (activated carbon), and in particular, two-component fibers 23 (bicomponent ), Which is mixed in the air 24, vacuumed with a vacuum collector 25 to form a mesh sheet 26 of an appropriate thickness, and then heated in an oven 27 to form a finished product 3. The two-component fiber 23 uniquely added in this case has the structure shown in the third figure. It has two layers of inner and outer layers. The internal structure 231 is made of PP. The melting point is about 160 ° C, and the outer structure 232 is It is made of PE. Its melting point is about 120 ° C or lower. Before the mesh 26 is heated by the oven 27, as shown in the fourth figure, the ultra-fine fibers 21, activated carbon material 22, and bicomponent fiber 23 are mixed and sandwiched in the mesh 26; however, when the mesh 26 is After being heated at an appropriate temperature of the oven 27 (about 130 ° C, or above 120 ° C, but not higher than 160 ° C), the ultrafine fiber 21 will shrink into a spherical shape due to heat, while the bicomponent fiber 23 The outer structure 232 will produce a melting phenomenon due to heat, but the inner structure 231 is still there (please read the precautions on the back — I install this page) The size of the paper is applicable to China National Standard (CNS) A4 (210X 297 mm) 496755 A7 B7 V. Description of the invention (j) Keep the original shape, so as shown in the fifth figure, the ultra-fine fibers 21 and activated carbon 22 in the mesh 26 will be melted by the two-component fibers 23 The structure 232 causes a sticking state. It is obvious that the addition of the bicomponent fiber 23 in this case can indeed improve the adhesion of the structure, so that no separation phenomenon will occur in use; and the ultrafine fiber 21 is reduced to a spherical shape due to heat, effectively making it The occupied space is melted and shrunk, so that the air circulation channel can be obtained, so as to achieve the purpose of greatly reducing the pressure loss. In summary, the "multi-fiber laminated activated carbon filter material" in this case has breakthrough advantages, indeed excellent effects, is extremely practical, has highlighted its practical value, and has not been disclosed or disclosed at home and abroad. In the literature and on the market, they are indeed in full compliance with the various elements of invention patents. They applied for patents in accordance with the law.
