Method for manufacturing non-woven fabric directly doped composite material

The invention relates to a related field of non-woven fabrics, in particular to a manufacturing method for directly doping composite materials such as activated carbon, nano silver, skin care raw materials, etc. in the production process of the non-woven fabric.

For the conventional non-woven fabric manufacturing method, please refer to FIG. 3 (Republic of China Patent No. I346158); the non-woven fabric manufacturing device 90 is provided with a permeable support member 200 for supporting the fiber web 100 from one surface side; The fiber web 100 supported by the ventilating support member 200 from one surface side is sprayed with the blasting means 910 which constitutes the blowing means of the fluid mainly composed of gas, and the other side of the fiber web 100. The air supply unit shown in the drawing; and a conveyor 930 as a moving means for moving the fiber web 100 in the predetermined direction F.

Further, the conveyor 930 is moved in the predetermined direction F by the fiber web 100 in a state of being supported by the air permeable support member 200 from one surface side, and the discharge portion 910 and the air supply portion (not shown) are connected to each other by the conveyor 930. On the other side of the web 100 moving in the predetermined direction F, a fluid mainly composed of a gas is blown.

Thereby, the fibers constituting the fiber web 100 are discharged (sprayed) from the discharge portion 910 by a fluid mainly composed of a gas and/or passed through the fiber web 100 and received by a non-venting portion formed in a ventilating support member to be described later. The fluid, which is mainly composed of a gas, is changed in flow direction to change the position and/or direction of the fibers constituting the fiber web 100. By adjusting the degree of change in the position and/or direction of the fiber, the fiber orientation, the fiber density, or the fiber base amount of the fiber web 100 can be adjusted, and a groove portion, an opening portion, or a projection portion having a predetermined shape can be formed.

The air intake portion 915 disposed on the lower side of the air-permeable support member 200 disposed below the discharge portion 910 is for sucking a gas ejected from the discharge portion 910 and further passing through the air-permeable support member 200. Here, the fiber web 100 can also be positioned to be posted by the suction of the suction portion 915. The air permeable support member 200. By the inhalation, the fiber web 100 can be conveyed in the heating unit 950 while maintaining the shape of the groove portion (concavity and convexity) formed by the air flow. In other words, it is preferable to carry out the air flow by the heating unit 950, and the suction unit 915 is preferably sucked from the lower side while being sucked.

The air supply unit (not shown) is connected to the discharge unit 910 via an air supply pipe 920.

The conveyor 930 is provided with a ventilating air-permeable belt portion 939 which is formed in a horizontally long annular shape, and is disposed in the longitudinal direction of the inner side of the annular air-permeable belt portion 939 which is formed in the horizontal direction. Rotating portions 931 and 933 that rotate the annular air-permeable belt portion 939 in a predetermined direction at both ends. As the air permeable belt portion 939, for example, a mesh belt portion is preferable. Similarly to the conveyor 930, the conveyor 940 may include a belt portion 949, a rotating portion 941, and the like.

The non-woven fabric produced by the above-mentioned non-woven fabric manufacturing process has a single thickness and cannot be thickened; if it is to be thickened, the amount of fibers which must be ejected at the ejecting portion 910 must be increased, or a plurality of ejecting portions 910 must be added. The fiber is sprayed out at different positions to superimpose the thickness; not only the process time is prolonged, but also the thickness is not easy to control, and the increased equipment is more costly.

The invention provides a method for manufacturing a non-woven fabric directly doped composite material, which can be directly doped into a composite material such as activated carbon, nano silver and/or skin care raw materials, and then rolled through a roller group to make the activity active. Carbon blending forms a non-woven fabric mixed with a composite material such as activated carbon, nano silver, and/or skin care raw materials; and is doped with composite materials such as activated carbon, nano silver, and/or skin care materials, and rolling operations. Between the use of different transmission speeds, the output of the non-woven fabric thickness is adjusted by stacking, without adding other equipment, and no additional process is required, which is not only convenient to manufacture, but also easy to adjust the thickness to provide a quick mask. A finished product such as a mask.
