JiLin Carbon Fiber Tow (also known as Carbon Fiber Yarn and Carbon Fiber Roving) adopts an advanced full-process chain, from Polyacrylonitrile (PAN) precursor fiber to stabilization, carbonization, surface treatment and precision sizing. Whether for filament winding, pultrusion, weaving feedstock, UD tape, prepreg manufacturing, braiding or chopping applications, JiLin Carbon Fiber Tow / Yarn / Roving delivers consistent quality, precise filament count control, excellent spreadability, superior resin wettability and batch-to-batch stability. The inherent softness and high performance from our proprietary wet-spinning technology make them the ideal foundation for high-end composite materials.
Carbon Fiber Tow / Yarn / Roving: Superior Processability

Protects filaments, improves abrasion resistance, enhances spreadability and significantly improves processing efficiency for downstream composite manufacturing.
Suitable for epoxy, vinyl ester, phenolic, and thermoplastic resin systems.
Sized tow maintains perfect bundle integrity during high-speed unwinding and processing.
Stabilized/Set Carbon Fiber Fabric: Unique Shape Stability
The adhesive spraying process of JiLin Carbon Fiber Fabric is our distinct feature, providing excellent shape retention capabilities suitable for composite applications requiring high stability. This stabilized design further reinforces the performance stability of our carbon fiber cloth under extreme conditions.

Carbon Fiber Fabric Applications
JiLin Carbon Fiber Tow / Yarn / Roving FAQ
- Is JiLin Carbon Fiber Tow suitable for Class-A surface or high-performance prepreg?Yes. Our wet-spun Carbon Fiber Tow has excellent spreadability and low fuzz, making it ideal for high-end prepreg production and Class-A surface applications.
- Does the sizing on Carbon Fiber Tow / Yarn / Roving affect resin wettability?No. We offer multiple sizing formulations specifically developed to maximize interface bonding without compromising wettability. Technical comparison data and resin matching support are available.
- What is the difference between Carbon Fiber Tow, Carbon Fiber Yarn and Carbon Fiber Roving?They all refer to continuous carbon fiber filaments. “Tow” is the general term. “Yarn” usually implies light twist for textile processes. “Roving” typically refers to large filament count (25K+). JiLin optimizes each variant for specific downstream processes while maintaining the same high base quality.
- How is the fuzz and filament breakage control of your Carbon Fiber Tow?Extremely low. We maintain world-leading standards in filament breakage and fuzz control through superior precursor, precise carbonization and advanced surface treatment.
- What are the common tow sizes (K number) and mechanical properties?We produce full range 1K–50K. Popular specifications include 3K, 6K, 12K, 24K and 48K. Standard HS grade offers tensile strength ≥ 5000MPa and modulus ~230GPa. Higher grades (IM/HM) are also available.
- What molding processes are your Carbon Fiber Tow / Yarn / Roving suitable for?Suitable for filament winding, pultrusion, weaving, braiding, prepreg (autoclave/RTM), chopping, and wet lay-up. We provide full technical support for process optimization.
- What is your production capacity and typical lead time?With 28+ carbonization lines and over 12,000 tons annual capacity, we offer very fast delivery. Standard products can be shipped quickly; custom sizing usually takes 2–4 weeks.
- What is the MOQ and packaging like?MOQ is very flexible — standard items from 1 bobbin, non-standard from 500kg. Professional anti-static, moisture-proof packaging ensures the Carbon Fiber Tow / Yarn / Roving arrives in perfect condition.
- Why choose JiLin instead of importing from Japan or USA?We offer equivalent or superior wet-spun fiber performance, significantly better pricing, the world’s largest production capacity, faster delivery, full-process technical support, and more stable supply chain security.
- How is the performance stability of high modulus carbon fiber under extreme temperatures?High modulus fiber performance is stable. Tested by CNAS laboratory Differential Scanning Calorimetry (DSC) instruments, supporting wind power-related certifications. The Limit Oxygen Index (LOI) can be measured to ensure reliable interface properties and wettability under high/low temperatures.
- Why choose JiLin instead of importing directly from Japan/USA?Choosing us avoids supply chain disruption risks and provides full-process technical support and high delivery speeds. Performance is at a world-class level, but with better pricing and the world's No. 1 capacity; strategic cooperation ensures stable supply.
