Plastic Additives on Knitting Industry Applications

Geotextiles Applications

Geotextiles are advanced geotechnical engineering materials made from synthetic fibers like PET, PP, and nylon. They are widely used in construction and environmental projects to provide:

• Reinforcement

• Filtration

• Drainage

• Impermeability

• Separation

• Protection

Due to their fine fiber structure and constant exposure to outdoor conditions, geotextiles are prone to photo-oxidative degradation, leading to fading, brittleness, and loss of strength. Incorporating UV stabilizers and antioxidants is critical to prolong their lifespan.

Recommended Additives for Geotextiles

• For Polypropylene (PP): LS-770, LS-944, LS-119, LS-622, L-860 (masterbatch)

• For Polyester (PET): LS-119, LS-622, UV-326, UV-328, UV-531

• For Nylon (PA): LS-114, LS-944, LS-119, UV-234

Rainproof Cloth Application

Rainproof cloth (also known as tarpaulin) is primarily made from PP or PE and is used in:

• Storage covers

• Construction sites

• Tents and military gear

• Agricultural and greenhouse shading

• Transportation covers (trucks, ships, etc.)

Due to harsh outdoor conditions including UV rays, moisture, and temperature changes, rainproof cloth requires effective weather resistance.

Recommended Additives for Rainproof Cloth

• Anti-aging additives: LS-791, LS-944

• These additives help maintain color, strength, and flexibility over time.

Shade Net Application

Shade nets (or agricultural shade cloths) made from HDPE or LLDPE protect crops by:

• Reducing heat stress

• Providing UV shielding

• Enhancing microclimate conditions

• Controlling pests

They require long-lasting UV stabilization due to continuous outdoor exposure.

Recommended Additives for Shade Nets

• Anti-aging additives: LS-944, LS-622, LS-119, LS-770 (0.3–0.8%)

• Anti-aging masterbatch: L-650, L-691 (1–3%)

Anti-Aging Requirements

Shade nets are expected to last 3–10 years outdoors. Lab-based UV aging tests are used to validate long-term performance.

Types of Plastic Additives Used in Plastic Knitting

UV Stabilizers

Prevent degradation caused by sunlight, helping maintain strength, color, and flexibility in outdoor applications like shade nets and awnings.

Antioxidants

Protect synthetic polymers from oxidation, especially under high heat and mechanical stress, extending the life of industrial textiles and automotive fabrics.

Plasticizers

Increase elasticity and softness, ideal for protective clothing, seat covers, and comfort-driven applications.

Colorants and Pigments

Provide vibrant, lasting color with high UV resistance.

Flame Retardants

Crucial for safety in environments where heat and fire risk exist, such as automotive interiors and industrial areas.

Antimicrobial Additives

Inhibit bacteria, fungi, and mold growth, useful in medical textiles and outdoor furniture covers.
