Embodiment Construction

[0025] The following process steps are completed in the same equipment:

[0026] 1. Prepare porous polyester fiber by supersaturated gas method.

[0027] The molding process of foamed materials generally goes through three main stages, namely, the formation of bubble nuclei, the expansion of bubbles, and the immobilization of bubbles. The specific process steps are: (1) Make nitrogen fully infiltrate polyester PET fiber under high pressure;

[0028] (2) Rapidly reduce the pressure to normal pressure; (3) Foam in a constant temperature furnace.

[0029] Use the positive and negative pressure system in the magnetron sputtering furnace (add a silicone ring with electromagnetic wire near the furnace door inside the furnace chamber, and control the internal suction and external pressure of the silicone ring through electromagnetic control to ensure that the furnace can meet the positive pressure, Negative pressure impact), at room temperature (25°C) with 8MPa pressure to fully in...

Abstract

The invention belongs to the antibacterial environmental protection field and in particular relates to an antibacterial active carbon fiber and a production method thereof. The antibacterial active carbon fiber is a polyester fiber adsorption material; a carbon and metal composite material coating is deposited on the surface of the porous polyester fiber material. The preparation process of the antibacterial active carbon fiber comprises the following steps: firstly, causing nitrogen to enter the free volume of the polyester fibers by an over-saturation foaming method; and then causing the nitrogen pressed into the free volume to expand through pressure reduction and temperature rise treatment to form lots of bubbles and fixing the shape of holes. The carbon and metal mixed target is deposited on the surface of the fiber material by a magnetron sputtering method.

Description

technical field [0001] The invention belongs to the field of antibacterial and environmental protection, and in particular relates to a carbon fiber with low cost, high adsorption and antibacterial and mildew-resistant activity and a manufacturing method thereof. Background technique [0002] Activated carbon (GAC) is a porous carbon that has been activated and has a strong adsorption capacity. It has been used in military, chemical, environmental protection and other fields for a hundred years. Activated carbon fiber (fibrous), the fiber is covered with micropores, its adsorption capacity for organic gases is several to dozens of times higher than granular activated carbon in air, 5 to 6 times higher in aqueous solution, and the adsorption rate is 100 to 1000 times faster. In the industry, use his super adsorption capacity to recover organic solvents, purify air, and purify water. [0003] Activated carbon fiber is a high-tech product. Only a few countries in the world can...
