What is ES hot air cotton?

What is the ES hot air cotton used to make KN95 masks? The difference between meltblown cloth and hot air cotton, as one of the KN95 folding mask materials, hot air cotton is not well known by the public. As a new type of mask material, hot air cotton non-woven fabric is widely used in N95 folding masks.

What is ES hot air cotton?

Hot air cotton, also known as tuyere cotton, is a new type of thermal insulation material, which is a replacement product of spray cotton and silk-like cotton. Hot air cotton is different from spray cotton. Its fixing method is not to use latex but to mix a certain amount of low-melting fiber or ES two-component fiber in the raw material. After heat drying in the production process, the fibers will be fused, so it is also a synthetic fiber filter cotton. one of them. The hot-air cotton production speed is fast, the output is large, and the cost is low.


"ES" in ES hot-air cotton is a composite fiber, which is the abbreviation of "Ethylene-Propylene Side BySide" in English, and refers to the name of the raw material. As a new type of thermally bonded composite fiber, ES fiber has been highly evaluated in the world. Among them, the "hot air" of hot air cotton refers to a process in which after the fiber is carded, the hot air on the drying equipment is used to penetrate the fiber web and heat it to bond the resulting non-woven fabric.

Can ES hot air cotton replace melt blown cloth?

1 ton of hot-air cotton without anti-cloth, can make about 600,000 KN95, N95 folding masks.

Due to the increase in the demand for masks, one of the raw materials needed to produce masksmelt blown cloth is also very scarce. Since the supply of melt blown cloth is so tight, can it be replaced by hot air cotton with filtering effect?


Everyone knows that "melt blown cloth", an important raw material for the production of masks, is commonly known as the "heart" of masks. It has good filtering, shielding, heat insulation and oil absorption properties, and can filter out viruses attached to body fluids. It mainly plays a filtering role in N95 masks and is an indispensable mask filter material.


The hot-air cotton non-woven fabric also called filter cotton, its filtering effect only achieves the initial filtering effect, therefore, it cannot replace the melt blown cloth. Since hot-air cotton non-woven fabric cannot replace meltblown fabric, what role does it play in N95 masks? Is it necessary material?

Hot-air cotton non-woven fabric is a kind of filling material in N95 masks. In order to take into account the effects of warmth and protection, some manufacturers use hot-air cotton non-woven fabrics with high bulkiness, good elasticity, soft feel, strong warmth, and good air permeability. Clamped in the middle of the N95 foldable mask, it mainly plays the role of heat preservation and heat insulation, moisture-proof and moisture-proof, and improves the comfort of the wearer.


Although hot-air cotton non-woven fabrics cannot replace melt-blown fabrics, both are N95 mask materials and are indispensable.
