Fiberglass Yarn Description：

Fiberglass yarn is a fiberglass twisting yarn.Its high strength, corrosion resistance, high temperature resistant, moisture absorption, good electrical insulating performance, used in weaving, casing, mine fuse wire and cable coating layer, the winding of electric machines and appliances insulating material, various machine weaving yarn and other industrial yarn.

Fiber Type: Glass fibers, typically made from soda-lime glass, borosilicate glass, or E-glass

Fiber Diameter: Typically ranges from 3-20 microns (μm)

Fiber Length: Can be continuous filament (not chopped or staple fibers) or chopped fibers of various lengths (e.g., 1/4", 1/2", 1", etc.)

Tex Count: Measures the yarn's linear density, with common tex counts ranging from 100 to 1000 Tex (1 Tex = 1 gram per kilometer)

Yarn Twist: Can range from 0 to 100 twists per meter (TPM), depending on the intended application and desired yarn properties

Yarn Color: Typically natural white or transparent, but can be colored through dyeing or pigmentation

Yarn Finish: Can have various finishes, such as lubricants, binders, or coatings, to enhance yarn performance and processing

Spinning Method: Can be wound, spooled, or tubed, depending on the specific product and manufacturer

Technical Data：

Packaging And Storage：

The products are mainly packaged in cartons or metal frames. Unless otherwise specified, the products should be stored in a dry, cool and moisture-proof area. The room temperature should be maintained in an appropriate range,preferably between 15°C~35°C. lt is best if the product is used within 12 months after the production date. The products should be kept in their original packaging prior to use.
To ensure safety and avoid damage to the products, the pallets should be stacked no more than two layers high When the pallets are stacked in 2 layers, special care should be taken to correctly and smoothly move the upper pallet.
