Problems solved by technology

[0004] The relative humidity resistance and fire resistance requirements of the filter cotton are two important performance indicators, but the filter cotton currently on the market has poor flame retardancy and humidity resistance
On the other hand, in the prior art, in order to achieve the flame-retardant effect of filter cotton, it is processed by adding flame-retardant fibers into the material ratio and spraying flame-retardant agents on the surface. The process is very complicated, and the flame-retardant effect is not special. Ideal, production costs are also particularly high

Abstract

The invention discloses high-flame-retardancy filter cotton. The filter cotton comprises, by mass, 10%-40% of 2-5D flame-retardant fibers, 20%-35% of 7D flame-retardant fibers, 25%-40% of 12D flame-retardant fibers and 5%-25% of 18-20D flame-retardant fibers. The flame-retardant fibers are formed in the mode that a fire retardant is added before fiber forming, and then drawing is carried out. The invention further discloses a preparation method of the flame-retardant filter cotton. The method includes the steps of (1) preparation of the flame-retardant fibers, (2) cotton blending, (3) opening, (4) combing, (5) lapping and (6) hot air setting. The flame-retardant filter cotton is good in flame-retardant effect. The flame retardant is added in the fiber preparation process, so that the flame-retardant effect is greatly improved. The flame-retardant filter cotton prepared through the preparation method of the flame-retardant filter cotton is good in flame-retardant effect and long in service life.

Description

technical field [0001] The invention relates to the field of air filters, in particular to a filter cotton used in filters and a preparation method thereof. Background technique [0002] With the development of industry, air pollution is becoming more and more serious, and the demand for air purification is also increasing. On the other hand, the air contains a large amount of dust (such as dust, dust, smoke, mine dust, sand dust, powder, etc.) Balance has an impact. [0003] The air in the home needs to be purified, the interior of the vehicle needs to be purified, and the public places need to be purified. There are also production workshops that need air purification. The most critical structure in the air purifier is the filter cotton. The quality of the filter cotton determines the purification effect of the air purifier. Filter cotton has its indispensable position, because many industrial productions must be carried out in a relatively clean space, such as surface...
