PLA Staple Fibre – Application Grades

 

 

 

• Nonwoven Grade (Thermal Bonding Optimized)

 

• Spinning Grade (Textile Applications)

 

• Filling Grade (Eco-Padding Solution)

 

Bio-Based & Biodegradable Sustainable Fibre Solution

 

PLA (Polylactic Acid) Staple Fibre is an environmentally responsible fibre derived from renewable plant-based resources such as corn starch and sugarcane. Produced through polymerization of lactic acid, PLA fibre offers a sustainable alternative to petroleum-based synthetic fibres while maintaining excellent processing performance.

 

As a bio-based polymer fibre, PLA combines ecological benefits with balanced mechanical properties, making it suitable for a wide range of textile and nonwoven applications.

 

 

Product Characteristics

 

Bio-based and renewable raw materials

Biodegradable under industrial composting conditions

Lower carbon footprint compared to conventional polyester

Soft hand feel and natural appearance

Good moisture vapor transmission

Lightweight with stable dimensional performance

Excellent processability in nonwoven and spinning applications

Skin-friendly and suitable for hygiene products

 

 

 

Performance Advantages

 

PLA fibre provides:Good tensile strength and elongation balance

Thermal bonding capability at relatively low temperaturesLow smoke emission during combustion

Natural resistance to UV degradation compared to many synthetic fibresIts lower melting point (compared to polyester) makes it particularly suitable for thermal bonding processes in nonwoven manufacturing.

 

 

Typical Applications

 

Spunbond and thermal-bonded nonwoven fabrics

Hygiene and medical nonwovens

Wipes and disposable products

Filling materials

Blended yarns for eco-friendly textiles

Agricultural and filtration materials

Sustainability Profile

PLA fibre is derived from annually renewable resources and can biodegrade under controlled composting conditions. It supports global sustainability initiatives aimed at reducing dependence on fossil-based materials and lowering environmental impact.
