PP (polipropileno) O tecido não tecido spunbond é feito usando máquinas não tecidas especializadas que extrusam filamentos de resina de polipropileno e os transformam em uma teia não tecida. Os tecidos resultantes têm muitas propriedades desejáveis para diversas aplicações. With the proper machinery and technology, manufacturers can reliably produce PP spunbond nonwoven fabrics with consistent properties at high throughputs for various end applications.
PP Spunbond Nonwoven Fabric Properties
- Chemical resistant – Resists degradation from most acids, alkalis and solvents
- Hydrophobic – repels water and resists moisture
- Abrasion resistant – Maintains strength after repeated abrasion and rubbing
- Elastic – Some PP spunbond grades exhibit elasticity
- Heat sealable – Can be heat sealed or welded for bonding and packaging
These properties make PP spunbond fabrics useful for filters, lenços umedecidos, geotextiles, hygiene products and more.
