what is non woven fabric made of
Non-woven fabrics are made from a variety of man-made synthetic fibers. Here are some of the most common fiber types used:
1.Polypropylene – One of the most widely used synthetic fibers for non-woven fabrics. It’s low-cost, durable, moisture-resistant, and has good mechanical strength properties. Commonly spun into filaments.
2.Polyester – Another top choice that is strong, dry-quick drying, and dimensionally stable. Often used in durable geotextiles and fabrics requiring heat-sealing. May be filament or staple fibers.
3.Rayon – A semi-synthetic fiber derived from cellulose (wood or plant fibers). It provides good moisture absorption properties and a soft feel. Used in baby wipes, dressings, etc.
4.Nylon – Stronger than polyester, it produces tough, long-lasting fabrics. Preferred for uses requiring abrasion-resistance like outdoor fabrics. Usually as filaments.
5.Spandex/Elastane – Helps add elasticity and stretch characteristics to non-woven materials. Used for medical wraps and inner layers of diapers.
6.Polyethylene – Produces waterproof, breathable fabrics like those used in agricultural and landscape applications.
7.Acrylic – Softer fiber that adds warmth and insulation properties to fabrics. Used in clothing linings, home goods.
8.Cotton – Provides natural absorption but is more expensive for non-woven uses. May be blended with synthetics.
The specific fibers, their construction (filament or staple), and blending variations allow manufacturers to engineer non-woven fabrics for a huge range of end use applications and performance characteristics.
