What is hot air cotton?
Hot air cotton is also called tuare 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 bicomponent fiber into the raw material. After thermal drying in the production process, the fibers are combined, so it also belongs to synthetic fiber filter cotton. Hot air cotton has fast production speed, large output, and low cost.
Characteristics of hot air cotton
1. Pure white, fluffy, soft feeling, good elasticity, strong warmth retention, good moisture absorption, and breathability.
2. The use of natural flame retardant fiber, and no dripping phenomenon. Has a permanent self-extinguishing effect. When the carded web is thermally bonded by calendering or through air, the low-melting material forms a melt bond at the intersections of the fibers. After cooling, the non-intersection fibers remain in their original state, "point bonding" rather than "zone bonding".
3. A dense carbonized layer forms during combustion. and low carbon dioxide content, producing only small amounts of non-toxic flue gas
4. Stable acid and alkali resistance, non-toxic, and does not produce any chemical effect. The product is naturally degradable and meets environmental protection requirements.
5. Disadvantages of hot air cotton: low strength and easy to deform.
Hot Air Cotton Functions:
1. In order to take into account the effects of warmth and protection, the manufacturer uses hot air cotton with high durability, good elasticity, soft hand feeling, strong warmth retention, and good air permeability and water permeability to sandwich the N95 foldable mask, which is heat insulation, moisture - Evidence and moisture – plays the role of evidence. , and improve wearer comfort.
2. Test items: test pH value, formaldehyde, air permeability, etc.
3. Hot air cotton (non-bonded cotton) is a new type of thermal insulation material, which is a replacement product of spray-bonded cotton and imitation silk cotton.
