[0002] Non-woven fabrics are also called non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc. They are made of polyester fiber and polyester fiber and are made through a needle-punching process. They can be made into different thicknesses, feels, hardness, etc. Non-woven fabrics are moisture-proof, breathable, thin, and flame-retardant. They can be used in different industries, such as electric heaters, masks, clothing, medical, filling materials, etc.

[0003] Flame retardancy refers to the property of a substance or a material after treatment that significantly delays the spread of flames. This definition covers the ability of a substance to slow down its burning speed and hinder the spread of flames when it encounters fire. Anti-stickiness refers to the anti-adhesion and anti-stickiness properties of the surface of an object. This property can reduce the effects of adhesion and sticking when the surface of an object comes into contact with other substances.
