What is Felted Wool?

Felted wool is a fabric made by matting together wool fibers using heat, moisture, and pressure. This creates a dense, non-woven warm, durable, and water-resistant fabric. It is used in many things, like hats, bags, slippers, and rugs, and can be used for embroidery and other decorations.

Boiled Wool: Characteristics and Benefits

Boiled wool is a fabric made by washing wool in hot water and then shrinking and tightening the fibers. This creates a dense, felt-like fabric that’s warm, wind-resistant, and water-repellent. It's used in coats, jackets, hats, and gloves, and is known for being soft, warm, and breathable. It is also durable and long-lasting, making it a popular choice for high-quality clothing.

How Boiled Wool is Made?

Boiled wool is made by washing wool in hot water and detergent to remove dirt and grease. The wool is then combined to align the fibers and placed in a machine with hot water and detergent. The machine agitates the wool, causing the fibers to shrink and tighten, creating a dense, felt-like fabric. After rinsing and drying, the wool is brushed or sheared to create a smooth texture. It can be dyed or treated with chemicals for color or properties. Finally, the boiled wool is cut and sewn into garments or accessories like coats, jackets, hats, and gloves.

Boiled Wool vs Felted Wool: Which One to Choose?

Boiled Wool vs Felted Wool are both generally hypoallergenic due to their processes (boiling and felting) that remove allergens like lanolin and dust mites. When comparing the breathability of felted vs boiled wool, boiled wool tends to be less breathable than felted wool. The dense nature of boiled wool, while providing excellent insulation and warmth, restricts airflow and can trap heat, making it less suitable.

One of the primary advantages of felted wool is its exceptional warmth and insulation properties. The tightly woven fibers create an effective barrier against cold weather, making felted wool ideal for crafting cozy garments, accessories, and home decor items. Whether knitting a winter hat, sewing a pair of mittens, or designing a decorative throw pillow, felted wool provides the warmth and comfort you need to stay snug and stylish all season long.

Felted wool offers superior durability and longevity compared to boiled wool. Its dense structure makes it resistant to stretching, tearing, and pilling, ensuring that your creations stand the test of time.

While boiled wool has its merits, felted wool is the superior choice for its durability, warmth, versatility, and aesthetic appeal.
