In what application scenarios is regenerated monofilament suitable?

Regenerated monofilaments—monofilaments made from recycled plastics such as PP, PE, PET, or nylon—are widely used in various fields with moderate performance requirements due to their lower costs and strong environmental benefits.

1. Brush filaments for industrial and cleaning applications

This is one of the primary applications of regenerated monofilament. For example:

• Street sweeper brush, street cleaning brush;

• Roller cleaning brushes and polishing brushes (for surface treatment of metal and wood);

• Household cleaning tools such as mop threads, scouring pads, and dishwashing brushes.
  These scenarios place certain requirements on the strength and wear resistance of monofilaments, but there’s no need to meet safety-grade standards—recycled materials are perfectly capable of handling the job.

2. Agricultural and Horticultural Materials

• Agricultural tying rope, plant support wire;

• Bird-proof netting, shade netting, seedling netting;

• Soft fencing or covering netting for gardening.
  These applications typically involve short- or medium-term loads, and the weather resistance and tensile strength of regenerated monofilaments are sufficient.

3. Standard packaging and strapping belts

• Lightweight strapping tape, braided rope;

• Cargo lashing straps (for non-lifting applications);

• Seam lines or handle threads for express delivery bags and shopping bags.
  As long as it doesn't involve overload or personal safety concerns, regenerated monofilament is an economical and practical choice.

4. Geotechnical and Construction Auxiliary Materials

• Non-structural geotextiles (used for subgrade isolation and drainage filtration);

• Concrete curing blankets, dust-control nets;

• Temporary protective netting for construction.
  In these applications, the materials primarily serve to isolate, filter, or cover, and do not have high requirements for long-term strength.

5. Auxiliary Supplies for Fisheries and Aquaculture

• Non-load-bearing mesh panels for aquaculture cages;

• Float ball connecting cable, identification rope;

• Fishing gear decorations or auxiliary components (not the main fishing line).
  Note: Not recommended for use on main fishing lines, trawl main ropes, or high-tension sections, as recycled materials may lack sufficient strength and stability.

6. Home and Daily Necessities

• Curtain weight thread, sewing thread (for low-strength applications);

• Toy filling fiber, decorative tassels;

• Pet grooming brushes, shoe brushes, and other personal care tools.
  If the product explicitly states that it uses food-grade or non-toxic recycled materials (such as GRS-certified rPET), it can also be used for certain contact-type products.

⚠️ Inappropriate use cases include:

• Personal safety products (such as seat belts, climbing ropes, and fall arrest harnesses);

• High-strength lifting slings and lifting accessories;

• Medical devices and materials that come into direct contact with food (unless explicitly certified as food-grade recycled);

• Critical structural components exposed long-term to high-intensity ultraviolet radiation or high-temperature environments (unless specially formulated with anti-aging additives).

In general, regenerated monofilaments are best suited for non-critical industrial and civil applications that are cost-sensitive, have high environmental requirements, and demand moderate or low mechanical performance. When selecting products, it is recommended to prioritize suppliers whose offerings have quality control and environmental certifications (such as GRS and ISO 14021) to ensure a balance between performance and safety.
