Why Carbonized Fiber Yarn for Gland Packing
Material AdvantageCarbonized fiber yarn is produced by controlled thermal treatment of precursor fibers, giving a yarn with high tensile strength, excellent elasticity and thermal stability. When braided into gland packing, this yarn produces a packing with high fiber strength and excellent durability — suited for shaft seals of reciprocating motion machines handling water and oil based fluids, solvent vapours and general chemical service. The yarn resists compression set and maintains sealing integrity through pressure and temperature cycling.
Core Advantages of PR109 Yarn
- High tensile strength and excellent elasticity for durable braided packing
- Thermal stability for continuous service in water, oil and solvent vapour environments
- Full pH range chemical resistance — acids, alkalis and general industrial media
- Low attack on shaft — reduces wear on the shaft sleeve or valve stem
- Stable braiding behaviour — consistent cross-section and surface finish
Construction & Options
- Standard PR109: spun carbonized fiber yarn without core
- PR109-GF: reinforced with glass fiber core for higher tensile strength
- PTFE impregnation: available for lower friction and improved chemical resistance
- Yarn count: standard counts stocked; custom counts produced to your braiding specification
- Supply form: bobbin, cone or spool; custom weights and lengths

Frequently Asked Questions
Buyer Q&AWhat is Spun Carbonized Fiber Yarn used for?
PR109 spun carbonized fiber yarn is used to braid carbonized fiber gland packing. It is not itself a finished packing — it is the raw yarn that packing manufacturers feed into a braiding machine. The finished packing is used for shaft seals of reciprocating machines, pumps, valves and soot blowers handling water and oil based fluids and solvent vapours.
What is the difference between standard PR109 and PR109-GF?
Standard PR109 is spun carbonized fiber yarn without a core. PR109-GF is the same yarn reinforced with a glass fiber core, which increases tensile strength and makes it suitable for higher-pressure and higher-speed applications where greater braid stability is required.
Is PTFE impregnation available?
Yes. PTFE impregnation is available on request. The PTFE fills the interstices of the yarn, improving chemical resistance across the pH range and lowering friction against the shaft. This reduces running temperature and slows wear on the shaft sleeve.
What yarn count and bobbin format are available?
Standard yarn counts are stocked and custom counts can be produced to match your braiding machine and cross-section size. Bobbins, cones and spools are all available with custom weights and lengths. Send your braiding machine specification and target packing cross-section and we will match the yarn count.
Do you supply yarn to third-party packing manufacturers?
Yes. A significant part of our yarn volume goes to other sealing manufacturers who braid their own packing. We supply in bulk, with OEM labelling and private brand packaging available on qualified volume orders. Material data sheets and batch traceability documentation accompany every shipment.
What certifications does Kaxite hold?
Kaxite Sealing operates under an ISO 9001:2015 certified quality management system. We cooperate with SGS for testing of FDA, RoHS and UL94 items. Material test certificates are available on request. Every batch is manufactured in our Ningbo facility with full material traceability.
Can I get a free sample before ordering?
Yes. A free sample of the exact yarn count and construction is available for qualified buyers so you can run it through your own braiding machine and check cross-section, twist behaviour and surface finish before placing a production order.
How do I request a quotation?
Send your yarn count or braiding cross-section, core option, PTFE impregnation requirement, quantity, bobbin format and destination port. Kaxite replies within 24 hours with a factory-direct quotation, lead time and packing details.
