In the high-precision world of synthetic fibers, PBT (Polybutylene Terephthalate) filament stands as a marvel of engineering. Unlike traditional Nylon (PA), PBT offers superior dimensional stability, exceptionally low water absorption (less than 0.1%), and a higher "memory" for bristle shape recovery.
As a leading PBT filament manufacturer, Jiasheng Industrial has perfected the extrusion process to ensure each strand meets rigorous chemical and physical thresholds. Our PBT filaments are specifically engineered for environments where humidity and chemical exposure are prevalent, making them the indispensable choice for premium toothbrush heads and professional makeup brushes.
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.
Because we want to get closer to consumers and understand the market needs in depth so that materials can be used more widely, in 2008 we joined forces with downstream manufacturers to start the production of hair brushes, toothbrushes, makeup brushes, and finished false eyelashes.
By integrating raw material synthesis with finished product manufacturing, we eliminate middleman markups and ensure 100% traceability from polymer pellet to the final bristle.
China's manufacturing hubs offer unparalleled access to advanced laser-micrometer extrusion technology, allowing us to control filament diameter to within ±0.001mm.
Our labs focus on "Information Gain" through material science, developing antimicrobial PBT and biodegradable filaments that meet the latest EU Green Deal regulations.
The global synthetic filament market is shifting towards Sustainability and Smart Application. As a PBT filament supplier, we observe three macro trends:
In response to plastic pollution, we are increasing the use of recyclable and degradable materials. Our rPBT (Recycled Polybutylene Terephthalate) filaments maintain 95% of the mechanical properties of virgin PBT while reducing carbon footprint by 40%.
Global procurement teams now demand specific functionalities: charcoal-infused PBT for whitening toothbrushes, or silver-ion coatings for antibacterial medical brushes.
To mitigate global uncertainties, we are building production bases in Thailand and Vietnam (2024). This ensures a stable, diversified supply chain for our European and North American partners.
We provide multi-level deep customization services to meet the needs of different customers. Our OEM/ODM capabilities include:
PBT filaments provide the necessary heat resistance for professional blow-drying and the flexibility for detangling sensitive hair.
Engineered "Silk-Touch" PBT mimics the softness of natural animal hair while offering superior hygiene and durability.
Our high-efficiency filaments for electric toothbrush heads are designed for 30,000+ vibrations per minute without losing structural integrity.
