Nonwoven fabrics are made by bonding fibres together without weaving. The two most common bonding methods are needle punching and thermal bonding. Choosing the right one determines your fabric's strength, weight, hand feel and cost.
Barbed needles mechanically interlock the fibre web. It needs no binder and handles heavy gram weights (100–2000+ gsm). Ideal for filtration felt, geotextile, leather base, automotive and glass-fibre nonwovens that require strength and heat resistance.
Heat melts low-melt fibres (e.g. PET/PE bicomponent) to bond the web. It produces lighter, softer fabrics (10–100 gsm) for hygiene, wipes and interlinings, but is limited by temperature-sensitive materials.
If you need a strong, thick or high-temperature fabric — filtration, geotextile, automotive — choose a needle punching line. For light, soft disposable products, thermal bonding fits better. Many modern lines combine both for multi-layer performance.
