Non-Woven Fabric for Office Chair Bases
Common materials for non-woven fabric used in office chair bases include ordinary non-woven fabric, high-density polyester non-woven fabric, and some products feature anti-tear and wear-resistant functions. Black non-woven fabric is widely used due to its dirt-resistant properties. The following provides an explanation from three aspects: material characteristics, application scenarios, and price ranges.
Ordinary non-woven fabric is a common choice for office chair bases, typically formed by high-temperature pressing of polyester or polypropylene fibers. Its core advantages lie in its low cost, good breathability, and natural degradability, meeting environmental requirements. However, after long-term use (e.g., three to five years), the fiber structure may exhibit shedding due to friction or aging, especially in areas with frequent contact or heavy loads. This type of non-woven fabric usually has a relatively low weight per square meter, making it suitable for scenarios with low durability requirements.
High-density polyester non-woven fabric enhances performance by increasing fiber density, with a weight per square meter exceeding 100 grams. Its notable features include resistance to pulling, deformation, and mildew when damp, making it particularly suitable for use in underfloor heating environments or humid regions. Polyester material itself has good chemical stability, resisting most acid and alkali corrosion, thereby extending service life. Some products also incorporate anti-mold agents or undergo waterproof treatment to further enhance environmental adaptability.
Functional non-woven fabrics, such as needle-punched non-woven fabric or polypropylene non-woven fabric, improve anti-tear and wear-resistant properties through special processes (e.g., needle punching reinforcement). These products have tightly interwoven fibers and a relatively hard surface, effectively resisting scratches or tears, making them suitable for high-frequency use scenarios. The price range is wide, from 1.25 yuan per meter to 10 yuan per meter, depending on fiber density, treatment process, and brand differences.
In terms of color selection, black non-woven fabric has become mainstream due to its dirt resistance, firm dyeing, and resistance to fading. Office chair bases are prone to accumulating dust or stains, and black reduces cleaning frequency while maintaining a clean appearance. Additionally, black dyes typically use more stable formulations, resisting fading from light exposure or friction over long-term use, preserving product aesthetics.
In practical applications, a comprehensive selection should be made based on the usage environment, budget, and durability requirements. For example, high-density polyester non-woven fabric is preferred in humid regions, functional products are suitable for high-frequency use scenarios, and ordinary non-woven fabric can be used in budget-limited and short-term use scenarios.
