6D x 102mm Flame-Retardant Acrylic Staple Fiber

6D x 102mm Flame-Retardant Acrylic Staple Fiber

Product Description

6D x 102mm Flame-Retardant Acrylic Staple Fiber is a high-performance specialty fiber manufactured from modified acrylic polymer with inherent flame-retardant properties. The flame retardant mechanism is integrated into the fiber structure, ensuring permanent and durable fire resistance that does not wash out or diminish over time.

Key specifications

• Fineness: 6 Denier (6D) – ideal for medium to coarse yarns and bulky textiles

• Staple Length: 102mm – suitable for woolen spinning and open-end spinning systems

• Material: Flame-retardant modified acrylic

• Flame Retardant Standard: Typically meets LOI (Limiting Oxygen Index) ≥ 28% – 32%, UL 94 V-0, and other international fire safety standards

Key features

• Excellent permanent flame resistance

• Soft hand feel similar to natural wool

• Good thermal insulation properties

• High bulkiness and cover factor

• Good color fastness and dyeability

• Self-extinguishing when flame source is removed

• No molten drip during combustion

Application

6D x 102mm Flame-Retardant Acrylic Staple Fiber is widely used in various textile sectors requiring fire protection combined with softness and insulation.

In protective textiles – This fiber is ideal for flame-resistant workwear, welding aprons, firefighter station wear, and industrial protective clothing for electrical and petrochemical industries. The 6D thickness provides durability while the 102mm length ensures good spinnability on woolen spinning systems.

In home textiles – It is commonly used for fire-safe blankets, upholstery fabrics, curtains, drapery, mattresses, and bedding materials. Public buildings such as hotels, theaters, hospitals, and schools often require flame-retardant textiles to comply with strict fire safety regulations.

In transportation – This fiber is suitable for interior fabrics in trains, buses, aircraft, and ships, including seat covers, headliners, wall coverings, and carpeting. Transportation fire safety standards demand permanent flame resistance, which this fiber provides.

In thermal insulation – The combination of 6D thickness and acrylic's natural warmth makes this fiber excellent for fire-resistant insulation layers in protective clothing, sleeping bags, and winter outerwear.

In non-woven applications – It can be used in needle-punched non-wovens for automotive interiors, filtration materials, and industrial barriers requiring flame resistance.

This fiber can be blended with other fibers such as wool, cotton, polyester, or viscose to achieve specific performance requirements while maintaining flame-retardant properties. It is suitable for woolen spinning, semi-worsted spinning, and non-woven production lines.
