Problems solved by technology

[0004] However, the non-woven fabric used in the car air-conditioning filter element will be used for human breathing after being filtered. When the non-woven fabric is covered with dust and other sundries for a long time, it is easy to breed a large number of harmful microorganisms such as bacteria on the non-woven fabric. Because it cannot be washed with water, it is difficult to remove the bacteria. If it continues to be used, it will affect the health of the passengers. Therefore, the non-woven fabrics used for automotive air conditioning filters are usually not reusable, so there is still room for improvement.

Embodiment 1

[0037] A non-woven fabric for automotive air-conditioning filters, comprising the following components in parts by mass:

[0038] 25 parts of bamboo fiber; 20 parts of lotus fiber; 20 parts of polyurethane fiber; 15 parts of titanium dioxide fiber.

[0039] Bamboo fiber is the common bamboo fiber in this area;

[0040] Lotus fiber is common lotus fiber in this field;

[0041] The polyurethane fiber is a common thermoplastic polyether polyurethane material in the field. Specifically, the polyurethane fiber is composed of polyethylene glycol: MDI: BDO = 1: 1.1: 0.1, wherein the molecular weight of polyethylene glycol is 4000;

[0042] Titanium dioxide is a common nano-titanium dioxide fiber in the field.

[0043] The preparation method of non-woven fabric is as follows;

[0044] (1) Weighing, as follows:

[0045] Weigh bamboo fiber, lotus fiber, polyurethane fiber and titanium dioxide fiber respectively according to the formula.

[0046] (2) Grinding, specifically as follow...

Embodiment 2

[0069] The difference with embodiment 1 is:

[0070] The non-woven fabric includes the following components in parts by mass:

Abstract

The invention belongs to the field of non-woven fabrics, and provides a non-woven fabric used for automobile air-conditioning filter cores. The non-woven fabric used for automobile air-conditioning filter cores is capable of solving a problem in the prior art that recycling is impossible to realize. The non-woven fabric comprises 25 to 30 parts of bamboo fiber, 20 to 25 parts of lotus fiber, 20 to25 parts of polyurethane fiber, and 15 to 20 parts of titanium dioxide fiber. According to a preparation method, the non-woven fabric is prepared from bamboo fiber and lotus fiber, the surface of thenon-woven fabric is smooth and submissive, adhesion of dust is not easily caused, the permeability is better, the hygroscopic is better, dust caking and bacterium breeding are reduced; adding of titanium dioxide fiber is capable of killing bacteria through photocatalysis after using of the non-woven fabric for a period of time, and realizing recycling, filtered air is ensured to be clean and harmless, and damage on the body of people in automobiles caused by breeding of a large amount of bacteria on non-woven fabric is avoided.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, more specifically, it relates to a non-woven fabric used for automotive air conditioning filter elements. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. [0003] Since the non-woven fabric is not tightly woven, it is easily damaged when washed. Therefore, when the non-woven fabric is used as a filter element, when the surface of the non-woven fabric is covered with dust and other debris, the dust can only be cleaned by blowing the wind to dredge the non-woven fabric. Continue to use after cloth mesh structure. [0004] However, the non-woven fabric used in the car air-conditioning filter element will be used for human breathing after being filtered. When the non-woven fabric is covered with dust and other sundries for a long time, it is easy to breed...
