Air-jet texturing forms an expanded yarn structure that can help build coverage and thickness in woven industrial fabrics.
The yarn combines the continuous-filament construction of glass yarn with a fuller textured form for further textile processing.
The published F and W product ranges offer different linear density options for lighter and heavier fabric constructions. Confirm availability of the required grade before ordering.
Bulked glass yarn is used in fabrics for insulation and industrial processing. The selected grade and finished textile must be checked against actual exposure temperature, chemicals and service conditions.
Bulked yarn can be woven into industrial filter cloth. Dust collection efficiency, permeability and service life should be assessed on the finished filter fabric, rather than on yarn tex alone.

Use fiberglass bulked yarn to produce woven fabrics for insulation covers and industrial equipment protection. Select the yarn and fabric construction according to the required fabric weight, thickness and actual heat exposure.
Texturized glass yarn can be woven into filter cloth for industrial dust-handling systems. The final filter specification should address dust characteristics, gas temperature, permeability, fabric finish and required filtration performance.
Bulked yarn can serve as a raw material for woven fire blankets and heat-protection textiles. Fire-performance claims and suitability for a particular standard require tests of the finished product.
Different yarn specifications can be considered for winding cloth, woven fiberglass tapes and other narrow fabrics used in wrapping and insulation.
The bulky yarn structure may suit selected decorative fabrics or filling applications where the particular glass-fiber specification is appropriate.
Typical industries: Power generation, cement production, metallurgy, chemical processing and industrial equipment protection.
Finished product | Information to send JLON | What to confirm |
Insulation fabric | Fabric weight, weave, heat exposure and finishing | Yarn grade and finished-fabric temperature suitability |
Industrial filter cloth | Dust type, gas temperature and target cloth specification | Yarn compatibility and finished-cloth performance |
Fire blanket | Intended use and finished-product requirements | Fabric construction and relevant testing |
Woven tape | Width, weave, thickness and processing method | Tex, twist, package and weaving performance |
Replacement for existing yarn | Current yarn grade, TDS and sample if available | Glass type, tex, filament diameter, sizing and trial results |
A matching tex value does not by itself guarantee interchangeability. Assess the yarn in your weaving process and test the resulting fabric for its intended use.
Characteristic | Bulked glass yarn | Smooth filament yarn |
Yarn structure | Air-jet textured and voluminous | Smoother and more compact |
Typical reason for selection | Bulk and coverage in a textile construction | A smoother yarn construction |
Product selection | Check fabric requirements and processing trial | Check fabric requirements and processing trial |
If you plan to replace a smooth yarn with a bulked yarn, compare both weaving behavior and finished-fabric properties.
JLON can review your current yarn specification or proposed application with its manufacturing partners. Depending on grade feasibility and order quantity, parameters to discuss may include:
· Linear density
· Glass type and filament diameter
· Twist
· Sizing or special treatment
· Package form and package weight
For efficient selection, send us your existing grade or TDS, a yarn sample if available, the finished fabric you make, trial and annual quantities, and your destination country.
Available specifications, customization, MOQ and lead time require confirmation for the requested grade.
Tell us the textile you intend to produce, and we will review available yarn options against your stated requirements.
We can use your current yarn designation or TDS as a starting point for specification matching and sampling.
JLON also supplies fiberglass fabrics and coated fiberglass cloth for buyers working across industrial textile applications.
Request grade details, available documents, sample options and a quotation based on your specification, quantity and destination.
A: Bulked yarn is processed by air-jet texturing, which creates a fluffy and expanded structure. Compared with regular smooth filament yarn, bulked yarn offers better insulation, improved filtration efficiency, and enhanced coverage.
A:F type generally refers to finer linear density ranges (66–1800 tex).
W type covers wider and heavier linear density options (66–4800 tex), suitable for thicker fabrics and heavy-duty applications.
Specific configurations can be customized according to customer requirements.
A: Yes. The yarn has a continuous working temperature resistance of up to 550°C, making it suitable for industrial heat insulation and filtration systems.
A: Yes. Its bulked structure improves dust capture efficiency and increases fabric thickness without significantly increasing weight, making it ideal for industrial filter cloth production.
A: Yes. We support customization in linear density (tex), twist level, package weight, and special treatments according to your application needs.
