Unlike traditional round nylon filaments, Spiral Filaments feature a hexagonal or twisted geometric profile. This increases the surface area contact by 35%, allowing for superior plaque disruption along the gingival margin. Our OEM processes ensure the spiral pitch is optimized for maximum mechanical cleaning efficiency.
The "spring effect" of nylon spiral bristles provides better reach into interdental spaces. By utilizing advanced PA610 and PA612 nylon resins, we achieve a balance between bristle stiffness and soft-tissue safety, reducing the risk of enamel abrasion while maintaining high durability.
Current R&D focuses on "Bio-mimetic Spiral Structures" that mimic natural textures to enhance fluid dynamics during brushing, improving the delivery of toothpaste active ingredients into sub-gingival pockets.
Shenzhen Jiasheng Industrial Co., Ltd. was established in 1991. At the beginning of its establishment, we mainly produced synthetic filaments, which were widely used in hair brushes, toothbrushes, makeup brushes, false eyelashes and other fields. After years of research and development, we have accumulated rich experience in the performance of filaments and the development and application of new materials.
In 2008, we joined forces with downstream manufacturers to start the production of finished hair brushes, toothbrushes, and makeup brushes. As plastics pollute the environment increasingly, we are looking for ways to continuously improve the service life of our products and increase the use of recyclable, degradable and other environmentally friendly materials.
In response to global geopolitical uncertainties, we have begun preparing to build production bases in Thailand and Vietnam in 2024.
Our Shenzhen facility integrates high-speed German and Italian tufting machinery capable of producing 1,000+ units per hour with zero-defect filament anchoring, ensuring every nylon spiral toothbrush meets stringent tensile strength tests.
We produce our own filaments. This vertical integration allows Jiasheng to control quality from the raw resin pellet to the finished toothbrush, reducing lead times by 20% compared to competitors who outsource raw materials.
By expanding to Thailand and Vietnam, we provide our global clients with "China Plus One" sourcing security, mitigating tariff risks and ensuring stable delivery for high-volume OEM contracts.

Custom packaging solutions ranging from eco-friendly FSC-certified paper boxes to premium magnetic closure gift sets, designed for Amazon and high-end retail shelves.
Spiral bristles provide 30-40% more cleaning surface due to their hexagonal/twisted shape. This creates more friction against plaque without requiring more pressure, making them gentler on gums while being more effective at cleaning.
Yes. We can adjust the nylon filament diameter (e.g., 0.15mm for soft, 0.18mm for medium) and the spiral pitch to meet specific regional preferences (e.g., the high demand for ultra-soft bristles in Asian markets vs. medium-stiff in European markets).
We use high-precision anchor-free or metal-anchor tufting technology. Every batch undergoes a "Pull-out Force Test" to ensure each tuft exceeds international safety standards (ISO 20126).
Standard lead times are 25-35 days for initial orders, including packaging customization. For repeat orders, we can reduce this to 15-20 days by maintaining a buffer stock of customized filaments.
Absolutely. All our resins (PP, ABS, TPE) and nylon filaments are 100% BPA-free and FDA-compliant, ensuring safety for all age groups.
