SAE Pressed Wool Felt

Wool scales are opened by hot-water wetting, then the wool fibers interlock, tangle and shrink through repeated mechanical kneading, rolling, beating and squeezing. Under continuous pressure, the fibers are densely compacted to form non-woven, glue-free and tightly structured felt boards.

1.Raw material pretreatment

Select high-quality wool → opening → cleaning and degreasing → removing grease and impurities to ensure clean and lint-free felt.

2.Wool laying

Lay wool evenly with thickness controlled according to finished product specifications.

3.Felt-forming solution spraying

Spray hot water at 45–65℃ mixed with a small amount of neutral soap solution or additives to wet the wool.

4.Rolling & felting (core process, needle-free compression)

Feed wool into roller press or hydraulic press. Repeated horizontal and vertical rolling and kneading make fibers interlock and compact under pressure to take shape gradually.

5.Squeezing & dewatering

Highpressure squeezing to remove excess water.

6.Drying & shaping

Dry in oven at 80–120℃ generally.

7.Hot-press finishing

Precise hot-pressing under high temperature and pressure to fix thickness, density and polish surface.

8.Post-treatment

Edge trimming, surface sanding and inspection to produce finished boards or rolls.

1.Dense structure with no pinholes, uniform texture.

2.Wear-resistant and long-lasting.

3.Good elasticity, shock-absorbing and pressure-resistant.

4.Excellent oil-absorbing, dust-proof and filtering performance.

5.Heat-insulating and sound-absorbing.

6.Gentle to workpieces, no scratches during polishing.

7.Stable shape, not easy to loose or deform.

8.Eco-friendly, glue-free and needle-free.

1.Polishing & grinding: for mirror-finish polishing of stainless steel, copper, aluminum, glass, ceramics and hardware, gentle without scratching workpieces.

2.Mechanical sealing: oil seals, shaft seals, dust-proof gaskets, oil-absorbing pads to prevent lubricant leakage.

3.Shock absorption: vibration-damping pads for machine tools, motors, automobiles and precision instruments.

4.Oil absorption & filtration: machine-tool oil absorption, lubricant and chemical dust filtration.

5.Heat & sound insulation: equipment thermal insulation, pipe heat preservation, automotive interior and musical instrument noise reduction.

6.Musical instruments: piano action parts and percussion instrument gaskets for stable tone.

7.Precision industry: enameled wire coating, semiconductor and electronic component protection.

8.Civil & cultural: calligraphy felts, heat-insulating mats, bag shaping and handcrafts.
