In the competitive landscape of the beauty and personal care industry, the quality of PBT (Polybutylene Terephthalate) Tapered Eyelash Filaments serves as the fundamental differentiator for premium eyelash extension brands. At Jiasheng Industrial, we have transitioned from being a raw filament pioneer in 1991 to a vertically integrated global leader, controlling the entire lifecycle from polymer extrusion to finished high-performance brushes.
Our PBT filaments are engineered to replicate the softness of natural mink while offering the durability and "shape memory" required for professional lash applications. This synergy of chemistry and craftsmanship ensures that every lash maintain its curl, resist environmental moisture, and provide a weightless experience for the end consumer.
Established in 1991, we possess deep-rooted knowledge in synthetic filament performance and polymer modification.
Launching new production bases in Thailand and Vietnam to optimize supply chain resilience and global logistics.
Pioneering the application of recyclable and biodegradable materials to reduce plastic pollution in the beauty sector.
The shift from petroleum-based PBT to bio-derived alternatives is no longer optional. Global brands are demanding filaments with lower carbon footprints without compromising tensile strength.
Advancements in laser-guided tapering allow for ultra-fine tips (down to 0.05mm), mimicking the natural taper of human lashes more accurately than ever before.
With eye health becoming a consumer priority, filaments infused with silver ions or other antibacterial agents during the extrusion process are gaining significant market share.
Our R&D roadmap focuses on three core pillars: Performance, Sustainability, and Intelligence.
Utilizing multi-stage tapering processes to achieve "Soft-Touch" textures. Integration of PCR (Post-Consumer Recycled) plastics into filament handles and brush components.
Establishing localized manufacturing in SE Asia (Thailand & Vietnam) to mitigate geopolitical risks and provide shorter lead times for European and North American clients.
Implementing AI-driven quality inspection systems to ensure 99.9% consistency in filament diameter and taper length, reducing waste in the downstream eyelash assembly process.
We provide full documentation for EU REACH, FDA, and RoHS compliance, ensuring your products enter any global market without regulatory friction.
From filament color (Pantone matching) to specific taper ratios (30% to 70%), our OEM/ODM capabilities allow for deep product differentiation.
By integrating material production and finished product manufacturing, we eliminate the "middleman margin," offering premium quality at factory-direct pricing.
Since our establishment, we have always prioritized investment in research and development, and have continuously tried innovative processes and cutting-edge materials to improve quality and efficiency. We have always regarded it as our responsibility to provide better quality products and minimize carbon emissions and reduce plastic pollution, constantly trying the application and substitution of environmentally friendly materials.
Customization capabilities: We can customize products according to customer needs, including design, material selection, functional configuration, etc., to meet customers' personalized needs.
Quality control: We have a strict quality management system from raw materials to finished products, which can ensure that product quality meets customer requirements and provide stable and reliable products.
