Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0030] A washable mixed fiber provided by the present invention includes non-degradable fiber and non-degradable bactericidal fiber, the mass percentage of non-degradable bactericidal fiber is more than 25%, preferably 25%-40%, and more preferably 25% %-30%; the non-degradable bactericidal fiber contains zeolite particles capable of releasing bactericidal metal ions (such as copper ions and silver ions), and the mass percentage of zeolite particles in the non-degradable bactericidal fiber is 0.3%-0.5%. The mass percentage of non-degradable fiber is less than 75%. Preferably, the mixed fibers may only include non-degradable fibers and non-degradable bactericidal fibers, that is, the sum of...

Abstract

The invention relates to a water washable mixed fiber, and a filter material and a filter prepared therefrom. The water washable mixed fiber comprises undegradable fibers and undegradable bactericidalfibers. The undegradable bactericidal fibers account for 25 wt% or more and contain zeolite particles which can release copper ions and silver ions. The mixed fiber is safe to use. Long term contacting is safe. The mixed fiber is safe for the respiratory system and will not generate any harmful substance or chemical. The silver ions and copper ions can generate a synergistic effect on killing bacteria and viruses, and the efficiency is high. The bactericidal effect is long lasting. The performance on killing bacteria and viruses can be maintained even after washing, wearing, and UV radiation.No harmful substance or waste gas is generated.

Description

technical field [0001] The invention relates to a washable mixed fiber and filter material and filter formed therefrom. Background technique [0002] Indoor and outdoor air quality is closely related to human health. At present, the pollutants in the air that have the greatest impact on human health are mainly three types: particulate matter, such as smog, dust, PM2.5, etc., will enter the bronchiole after being inhaled into the human body Even alveoli, and can enter the circulatory system through the blood-air barrier, causing asthma and other diseases; gaseous pollutants, formaldehyde, benzene, ozone, hydrogen sulfide, etc., long-term inhalation of gaseous pollutants can cause headaches, dizziness, fatigue, sensory disturbances, immunity Drops, etc., and there is a risk of cancer; microorganisms, bacteria, viruses, mite corpses, dander, etc., can cause illness and allergies after being inhaled into the human body. [0003] Since there are so many harmful substances in the...
