Fiberglass towels are functional cleaning cloths made primarily from glass fiber, designed for high-performance cleaning tasks. Unlike traditional cotton or polyester towels, fiberglass towels excel in high-temperature resistance, chemical corrosion resistance, and ultra-clean performance, making them widely used in industrial, laboratory, and other professional environments.

1. Core Material & Weaving Process

Material Composition

• Main material: E-glass (alkali-free) or medium-alkali glass fiber with fiber diameters ranging from 6–13 μm. Single fibers are strong and have higher elastic modulus than cotton or polyester fibers.

• Alkali-free glass fiber: Alkali content <0.8%, chemically stable, corrosion-resistant, electrically insulating, and the most common raw material for fiberglass towels.

• Medium-alkali glass fiber: Lower cost, slightly weaker acid resistance, suitable for less demanding cleaning tasks.

• Some products feature fiber impregnation treatment to reduce brittleness, improve flexibility, and minimize shedding.

Weaving Techniques

• Basic weaving: Plain weave, twill, or satin weave. Plain weave provides uniform density and durability, twill offers flexibility, satin has smooth surfaces for precise wiping.

• Surface treatment: Processes like heat-setting, singeing, and calendering remove loose fibers and create a smooth, lint-free surface. Some high-end towels have silicone oil coatings to reduce static and dust attraction.

3. Key Performance Advantages

1. High-Temperature and Corrosion Resistance
   Glass fibers are non-flammable and withstand temperatures up to 300℃. Ideal for wiping hot industrial equipment, ovens, or chemical-resistant surfaces without reacting with strong acids and bases (except hydrofluoric acid).

2. Ultra-Clean, Lint-Free
   Singeing and calendering remove loose fibers, preventing lint during cleaning. Perfect for precision instruments, optical lenses, and electronic components without scratching or contamination.

3. Water and Oil Absorption
   Fibers’ capillary structure absorbs 3–5 times their weight in water or oil, leaving surfaces streak-free and clean, improving Cleaning efficiency compared to standard cotton towels.

4. Durable and Reusable
   High fiber strength resists tearing and deformation. Can withstand repeated washing, abrasion, and maintains structure for 5–8 times longer than ordinary cleaning towels.

4. Applications

1. Industrial: Cleaning oil and dust on machinery, molds, metal components, high-temperature furnaces, and boiler walls. Precision cleaning for electronics manufacturing.

2. Laboratory: Cleaning glassware and lab instruments without lint, wiping surfaces exposed to corrosive reagents (except hydrofluoric acid).

3. Household: Oven, microwave, kitchen range hood, and automotive engine cleaning; avoids scratches with care.

4. Specialized: High-temperature cleaning in firefighting or metallurgy, aerospace precision component cleaning.

5. Usage & Maintenance

Usage Restrictions

• Avoid hydrofluoric acid, concentrated phosphoric acid, or other highly corrosive substances.

• Use thin satin weave towels for delicate surfaces like painted metal or acrylic to prevent scratches.

• Do not expose to temperatures above 500℃ for long periods, as fibers may become brittle.

Care Instructions

• Wash with neutral detergent at ≤40℃; gentle hand or machine wash. Avoid aggressive scrubbing.

• Air dry in a ventilated area; avoid direct sunlight to prevent fiber aging.

• Store in a dry environment; avoid sharp objects and damp conditions.

Safety Tips

• Direct contact with untreated fiberglass may cause slight skin irritation; wearing gloves is recommended.

• Wash after use to remove any residual fibers.
