Answer: Tyvek is a registered trademark of DuPont’s series of nonwoven technology products. Tyvek anti-mite fabric (ADM) is a unique product made through DuPont's original flash evaporation method. It combines the advantages of paper, film, and cloth, and has stable and balanced physical properties. It is a high-tech product The special fabric can only be produced by DuPont in the world. The functions of DuPont Tyvek include: 1. Physical anti-mite: good anti-mite effect, using particulate structure to block and filter, absolutely blocking dust mites and their excreta, preventing the passage of dust, dander, and body sweat, and preventing skin and respiratory diseases It is harmless to the human body without any chemical treatment and ensures a healthy sleeping environment. The following data (average of three parallel copies) is the data of TyvekADM testing by the national authoritative institution, Shanghai Institute of Preventive Medicine.

Good protection ability, superior resistance to chemical substances: chemically inert to most acids, alkalis, and salts, and good liquid barrier protection function. 3. Waterproof and breathable: porous material with good breathability. Due to the fineness of the fibers, liquid water, oil, etc. cannot easily penetrate; while gas and moisture can pass through, and it has excellent waterproof and breathable properties. 4. Good anti-penetration function of solid particles: The special physical structure can completely block fine mites and dust and prevent their penetration. 5. Excellent bacteria-blocking effect: making it suitable for packaging of sterile medical products.
