Product Description

Low Melt Nylon 66 Staple Fiber, 4D × 51mm

Product Introduction

Low Melt Nylon 66 Staple Fiber (4D × 51mm) is a bicomponent thermoplastic fiber designed for thermal bonding applications. The "Low Melt" designation indicates that the fiber has a lower melting point compared to standard Nylon 66, allowing it to act as an adhesive binder when heat is applied, without completely melting or losing its fibrous structure.

Key Specifications:

Fineness: 4 Denier (4D) – provides good coverage and bonding strength
Cut Length: 51mm – suitable for nonwoven processing lines (carding, airlay)
Material: Nylon 66 copolymer – offers excellent thermal stability, chemical resistance, and mechanical strength

Key Properties

Activation temperature: Typically 120°C – 160°C (lower than standard Nylon 66’s ~255°C melting point)
Bonding strength: High adhesion to various substrates
Processing compatibility:
- Can be blended with other fibers (polyester, cotton, glass fiber, aramid)
- Compatible with thermal calendering, hot air through-bonding, and oven bonding
Soft hand-feel: Maintains flexibility while providing structural integrity

Product Specifications

Denier: 1.2D~80D
Cut length: 38mm~120mm
Color: White/black
Raw material: 100% nylon (PA6, PA66 chips), high hardness
Shape: trilobal/round/hollow/flat
Luster: bright/dull/semi-dull
Delivery: 2-3 weeks after order confirmation
Packing: 200kg bales (115×95×75 cm) in weaving bags
MOQ: 8 ton
Monthly capacity: 2000 ton

Industrial Uses

Concrete reinforcement, tire cord, hoses, conveyor belts, seat belts, air bags, parachutes, racket strings, ropes, nets, and dental floss

Applications

This fiber is widely used in nonwoven manufacturing where form stability, high strength, and reliable thermal bonding are required.

Automotive Industry
The fiber is used for headliners, trunk liners, interior carpet backing scrim, and insulation pads. Its heat-activated bonding properties create durable, dimensionally stable components that withstand the demanding conditions inside vehicles.

Filtration
In filtration applications, it serves as a bonding agent for multi-layer filter media and pleated cartridge filters, ensuring structural integrity while maintaining open pores for efficient airflow.

Home and Industrial Textiles
The fiber is found in bonded interlinings for garments, furniture padding for seat cushions and armrests, as well as mattress edge reinforcement components. It provides a good balance of softness and structural support.

Construction Materials
Acoustic panels and insulation batts benefit from this fiber as it can partially replace chemical binders such as glass fiber or rock wool binders, offering a lower-emission alternative.

Specialty Nonwovens
Additional applications include abrasive backing paper and geotextiles used for erosion control and drainage systems.
