Problems solved by technology

Although the fiber has certain antibacterial properties, it needs to be under the condition of ultraviolet light to maximize the effect of titanium dioxide. Once there is no ultraviolet light, its antibacterial performance will be greatly reduced

Abstract

The invention discloses antibacterial and breathable philodendron-containing modified fiber. The fiber comprises a fiber body and an antibacterial film coating the fiber body, wherein the fiber body is composed of the following components in percentage by weight of 40 to 55 percent of milk protein fiber, 30 to 45 percent of bamboo fiber, 10 to 15 percent of jute fiber and 5 to 10 percent of philodendron fiber; and an active ingredient of the antibacterial film is a mixture of chitosan / metal ion doped nano titanium dioxide. The invention further discloses a preparation method of the antibacterial and breathable philodendron-containing modified fiber. The modified fiber is coated with the antibacterial film, and the antibacterial film is safe, non-toxic, non-irritant to the skin, high in antibacterial capacity, capable of killing bacteria under the visible light condition and even the dark condition, and wide in antibacterial range.

Description

technical field [0001] The invention relates to the technical field of mattress processing, in particular to a modified fiber containing philodendron and having antibacterial air permeability and a preparation method thereof. Background technique [0002] Mattresses are easy to breed bacteria after being used for a long time, but because the mattress is heavy and bulky, it cannot be cleaned, and it is not easy to move so that few people put the mattress outside in the sun for sterilization. If things go on like this, it is easy Cause allergies or other diseases of users, in view of this, the concept of antibacterial mattresses has been proposed. [0003] The Chinese patent with the publication number CN107692651A discloses a multifunctional mattress with silver-containing fiber, weather-resistant, flame-retardant and antibacterial. The mattress uses silver-containing fiber material to solidify the protein inside and outside the bacterial cell membrane, blocking bacterial rep...
