Overview
Recycled polyamide 6.6 selvages and yarns offered for compounding and melt extrusion. Material is supplied as recovered fiber remnants suitable for reprocessing into thermoplastic compounds.

About Polyamides
Polyamides are a family of crystalline polymers commonly represented by PA6 and PA6.6. They are produced and used in forms such as thermoplastic pellets and fibers. Blends of different polyamide types or combinations with other polymers (e.g. PE, PP) are used to tailor material properties for specific industrial applications.

Polyamide formation
PA6 is typically produced via a hydrolytic or ring-opening polymerization route (caprolactam), while PA6.6 is formed by step-growth polycondensation between diacids and diamines. These differences influence melting point, crystallinity and mechanical behavior.

Recycling processes
Mechanical recycling (grinding, melt extrusion and pelletizing) is the primary route for converting polyamide textile waste into reprocessable feedstock for compounding. Chemical recycling (depolymerization to monomers) is an alternative for monomer recovery and closed-loop reuse; its applicability depends on contamination levels and economic considerations.

Types available

• Recycled Polyamide 6.6 (selvages / yarn remnants)
• Recycled Polyamide 6 (fiber remnants)

Applications and targeted industries
Suitable for compounders and manufacturers requiring recycled polyamide feedstock for melt extrusion, pelletizing and fiber-reinforced thermoplastics. Target industries include textile recycling operations, technical textiles, automotive compounds and industrial component manufacturing.

Material properties (comparative)

• Both PA6 and PA6.6: good wear resistance and high elasticity.
• PA6: improved machinability, lower deformation tendency and generally lower material cost.
• PA6.6: higher rigidity, higher melting point and greater resistance to temperature and abrasion.
