Fiberglass Plied Yarn
F.I.T. (冠閤企業) is Taiwan's earliest manufacturer of Fiberglass Plied & Twisted Yarn, with over 20 years of precision twisting expertise. Through proprietary process parameter control and an extensive raw yarn supply network, we deliver custom plied yarn and hybrid twisting solutions to industrial customers worldwide.
As Taiwan's earliest manufacturer of Fiberglass Plied & Twisted Yarn, F.I.T. understands that the physical performance of glass fiber determines the success or failure of finished products in high-end industrial and specialty construction material applications.
3 Key Differentiators
Precise Raw Yarn Matching from Major Manufacturers
Each raw yarn manufacturer uses different sizing agents during production, which means yarns of identical specifications can exhibit different physical properties in downstream processing. F.I.T. maintains long-term strategic partnerships with major raw yarn manufacturers both domestically and internationally, enabling us to precisely select the most compatible raw yarn based on your end process and chemical coating requirements.
Precision Process Parameter Control
Many factories can operate twisting machines, but very few teams can rapidly adjust tension and speed while optimizing production parameters for varying strand counts and twist requirements. F.I.T.'s experienced production team can customize twisting conditions based on your actual equipment setup — whether high-speed weaving or braiding machines — helping you significantly improve downstream production efficiency and yield rates.
Broad Glass Specification Coverage
Our primary twisting material is high-grade alkali-free continuous glass fiber (E-glass). To address extreme environments and specialty industry needs, we also have extensive processing and development experience with alkali-containing glass (A-glass) and high-strength/high-temperature glass (S-glass) specialty yarns.
Technical Production Range
Leveraging precision equipment and superior process control capabilities, F.I.T. can perform accurate processing across an extremely wide range of technical specifications to meet diverse customer requirements:
| Specification | Production Range |
|---|---|
| Glass Fiber Type (TEX) | 2.3 ～ 272 |
| Glass Fiber Type (BC) | BC2250 ～ K18 |
| Number of Strands | 2 ～ 20 |
| Twist (TPI) | 0.7 ～ 10.0 |
| Twist (TPM) | 28 ～ 400 |
F.I.T. is fully proficient in internationally recognized fiberglass naming standards. Whether your R&D or procurement team works with metric or US system specifications, we can precisely deliver the corresponding precision processing.

Fiberglass yarn itself possesses top-tier physical properties including electrical insulation, high tensile strength, dimensional stability, and high-temperature resistance. Through different precision production parameter settings, F.I.T. perfectly interfaces plied yarn with various downstream processing technologies, giving rise to the following four core industrial application sectors:
ISpecialized Industrial Threads
Plied yarn used directly as a critical thread material in production processes, providing outstanding abrasion resistance and tensile strength:
Fiberglass Leno Yarn
Specifically used for "selvedge binding" during the weaving of thin and ultra-thin fiberglass fabrics, ensuring the fabric structure does not unravel or deform.
Fiberglass Sewing Thread
Typically PTFE-coated in post-processing to achieve greater toughness and durability, capable of withstanding high-speed repeated bending during production.
IIWeaving & Coated Fabric Materials
Combined with diverse weaving patterns and composite post-processing based on different thickness requirements, fibers are given entirely new multi-purpose applications:
Basic & Specialty Woven Fabrics
Plied yarn withstands high-tension weaving to produce foundational industrial fabrics used as base materials for various downstream processing.
Personal Protective Fire Blankets / Fire Suits
Extended into high-safety-grade personal protective fire blankets and fire suits, widely used in industrial safety environments.
High-Temperature Conveyor Belts / Abrasive Disc Reinforcement
Further processed into conveyor belts for high-temperature ovens and reinforcement layers for heavy-industry abrasive discs, providing critical structural support.
PTFE-Coated Architectural Membranes
Through impregnation processing, converted into premium PTFE-coated architectural membranes for tensile roof structures and complex building exteriors.
IIIBraiding & Texturized Applications
Through braiding machines or air-jet texturizing processes, yarn structure is modified for filtration and protection applications:
Thermal Insulation Sleeves
Plied yarn braided into tubular form and coated with specialty resin — widely used for insulating high-temperature industrial pipelines, reducing heat loss while preventing burns to on-site workers and improving workplace safety.
High-Efficiency Industrial Filter Bags
Combined with air-jet texturizing to make yarn structure bulky, greatly increasing surface area and porosity — specialized for gas/liquid filtration bags in high-temperature industrial environments.
Cut-Resistant Gloves
Leveraging fiberglass's high rigidity, typically co-braided with metal yarn, enabling finished gloves to simultaneously maintain wearing comfort and exceptional cut-resistant toughness.
IVRubber Reinforcement & Tape Cores
Utilizing fiberglass's near-zero elongation (dimensional stability) and electrical insulation properties as a strong internal skeleton for other materials:
Timing Belts
Leveraging fiberglass's exceptional dimensional stability as the belt's internal core yarn — providing unidirectional tensile support, perfectly preventing deformation and elongation under sustained high-speed operation.
High-Strength Adhesive Tape
Combined with specialty adhesives to give tape exceptional tensile strength beyond conventional limits — applied in heavy-load binding and electronic insulation.
