Basalt Fiber Yarn
Model:KXT
KXT series is a continuous basalt filament yarn — the raw material stage from which our braided rope, woven tape, woven cloth, and knitted sleeving are all made. It carries the same material profile as the finished forms: high-temperature resistance, acid and alkali resistance, flame retardancy, electrical insulation, and low moisture absorption. Yarn is supplied on spools for braiding, weaving, knitting, or pultrusion, in single-strand or plied construction to your specification. Send your downstream process, required linear density (tex), and spool weight for a same-week factory quote.
Basalt Fiber Yarn — Raw Material for Braided Rope, Woven Tape, Cloth and Sleeving
KXT series basalt fiber yarn is a **continuous filament yarn supplied on spools**, not a finished product. It is the raw material from which all of our basalt fiber finished forms are made — braided into rope, woven into tape and cloth, knitted into sleeving, or pultruded into composite profiles. If you already have **braiding, weaving, or knitting equipment** and want control over the final construction, buy yarn. If you need the finished form directly, see Basalt Fiber Rope, Basalt Fiber Tape, or Basalt Fiber Cloth.
Yarn or Finished Product — Which Should You Buy?
This Product
Basalt Fiber Yarn
Buy yarn when you process the fiber in-house. The yarn gives you control over the linear density, twist, plied construction, and spool weight — so the braid, weave, or knit comes out the way your specification requires. Ideal for workshops already running braiding, weaving, knitting, or pultrusion.
Alternative Path
Finished Rope / Tape / Cloth / Sleeving
Buy the finished form when you need the product ready to install or sell and do not want to run the downstream process. Same basalt fiber, already braided, woven, or knitted to a standard construction. See the four finished products linked below.
The Four Downstream Paths — Where Yarn Goes Next
Basalt Fiber Yarn Continuous filament · on spool
Braiding Braided Rope Rope for boiler, coke oven, industrial oven and stove door seals. See Basalt Fiber Rope.
Weaving Woven Tape Narrow woven tape for wrapping, lagging, and insulation work. See Basalt Fiber Tape.
Weaving Woven Cloth Wide woven cloth for laminates, lining, and high-temperature draping. See Basalt Fiber Cloth.
Knitting Knitted Sleeving Sleeving for cable, hose and pipe protection. See Basalt Fiber Sleeving.
Two Construction Variables — You Specify, We Produce
Construction
Single-strand or plied. Single-strand is used where the downstream process accepts finer input; plied yarn is used where a heavier, more uniform bundle is required. State the downstream process and we will confirm which construction suits it.
Linear Density (tex)
Confirmed at order. Tex is driven by the downstream process — a braid for door seals, a weave for tape, and a weave for cloth all call for different tex. State the target tex or the finished gram-per-square-meter specification, and we will match the yarn.
Twist Level
Confirmed at order. Twist affects both the yarn handling on your equipment and the surface character of the finished braid or weave. State the twist if your process requires it, or leave it to our technical recommendation based on your downstream process.
Spool Weight & Core
Confirmed at order. Spool weight is chosen to match your creel or winder — too heavy a spool causes tension problems on fine braiders, too light a spool causes excessive spool changes. State your machine's spool weight range and core type (paper, plastic, or steel).
Five Things to Send for an Accurate Yarn Quote
1
Downstream Process Braiding, weaving, knitting, or pultrusion — this determines the construction and tex baseline.
2
Linear Density (tex) Either the required tex of the yarn, or the finished form's specification (g/m², g/m, or rope diameter) so we can back-calculate.
3
Construction Single-strand or plied. If plied, the number of plies. If twisted, the twist level.
4
Spool Weight & Core Type Your machine's spool weight range and core material — paper, plastic, or steel.
5
Quantity & Delivery Total kilograms per order, number of spools per carton, and destination port. Sample quantities accepted for process validation.
6
Existing Specification (if substituting) If you are replacing a glass fiber or aramid fiber yarn, include the existing specification — we will confirm whether basalt fiber is a suitable substitute.
Properties Carried Into the Finished Form
Temperature Resistance
Basalt fiber is inherently high-temperature resistant — the property is carried from the yarn into the braided, woven, or knitted finished form. See Basalt Fiber for the material overview.
Chemical Resistance
Acid and alkali resistant — critical in pollution control equipment, chemical ducting, and pump shaft packing.
Flame Retardancy
Non-combustible mineral fiber — no halogenated flame-retardant treatment required.
Electrical Insulation
Good dielectric properties — used in knitted sleeving for cable and hose protection.
Low Moisture Absorption
Low moisture pickup relative to organic fibers — stable properties under humid storage and wet service.
Resin / Concrete Bonding
Strong bonding force to concrete and resin — this is why basalt fiber yarn is used in pultrusion and in composite reinforcement.
Procurement FAQ
What is basalt fiber yarn used for?
It is the raw material for four downstream products — braided rope, woven tape, woven cloth, and knitted sleeving — plus pultrusion composite profiles. Buyers who braid, weave, knit, or pultrude in-house purchase yarn; buyers who need the finished form buy the finished product directly. See Basalt Fiber for the material family.
Should I buy yarn or the finished rope, tape, or cloth?
Buy yarn when you process the fiber in-house and want control over the construction. Buy the finished form when you need the product ready to install or sell. The finished products are Basalt Fiber Rope, Basalt Fiber Tape, Basalt Fiber Cloth, and Basalt Fiber Sleeving.
What information do I need to provide for a yarn quote?
Downstream process, target linear density (tex) or finished form specification, construction (single-strand or plied), twist level if applicable, spool weight and core type, quantity, and destination port. See the six-point list above for details. Send these with the inquiry form below and our technical sales team responds within 2 business hours.
Does the yarn carry the same properties as the finished rope, tape, and cloth?
Yes. The finished forms are made from the same basalt fiber. The material properties — high-temperature resistance, acid and alkali resistance, flame retardancy, electrical insulation, low moisture absorption — are inherent to the fiber and are carried through to the finished construction. The downstream process changes the form, not the material.
Can basalt fiber yarn replace glass fiber or aramid fiber in my process?
In selected applications, yes. It is a candidate substitute where the higher temperature ceiling, acid and alkali resistance, and flame retardancy of basalt are advantageous. Suitability depends on your processing temperature, resin system (for pultrusion), and required mechanical properties. Send your existing yarn specification for our substitution review. For the wider insulation product family, see Insulation Products.
