1.Teasel Brushing: Nature-Inspired Softness

(Plant Brushing / Teasel Raising)

Teasel brushing represents the highest standard of cashmere finishing.

We use dried natural teasel thistles to gently brush the fabric in a controlled, damp environment.

How it works

Teasel hooks have a natural elasticity. When they meet a strong fiber node, the hook breaks instead of tearing the cashmere fiber—unlike metal needles, which pull aggressively and cause damage.

Resulting look & feel

This process preserves the delicate scale structure of cashmere fibers, creating a surface with a natural, water-ripple sheen and a soft, buttery hand feel.

This organic glow and tactile depth cannot be fully replicated by any mechanical alternative.

This technique is widely favored by top luxury brands such as Brunello Cucinelli and Loro Piana, and is best suited for ultra-luxury cashmere garments.

2. Mechanical Brushing: Precision and Efficiency

(Needle Brushing)

Mechanical brushing is the backbone of modern industrial production.

It uses metal or carbon-fiber needles mounted on rotating drums to pull fibers from the yarn surface.

How it works

By adjusting needle depth and drum speed, fibers are raised quickly and evenly.

Best use case

This method prioritizes surface uniformity and production consistency.

However, for ultra-fine baby cashmere below 15 microns, improper settings may damage fibers, reducing long-term durability and wear resistance.

3. Water-Wash Napping: Time-Driven Craftsmanship

(Our Most Valued Technique)

This is the technique we believe in most—and also the one with the highest technical barrier.

Water-wash napping is not about mechanical force. It is about the perfect coordination of water flow, chemistry, and time.

Soft-Water Pre-Treatment

We use specially treated soft water with hardness below 50 ppm.

Gentle clockwise water movement creates controlled fluid friction, allowing hollow cashmere fibers to naturally emerge from within the yarn under water lubrication.

Human Observation & Control

This process is slow and labor-intensive.

Experienced craftsmen monitor fiber density, length, and distribution by eye, adjusting washing rhythm in real time.

Eco-Safe Fixation

When the nap reaches its optimal state, we lock it using EU-compliant, food-grade finishing agents.

The result is a nap that is full, natural, and resilient, with significantly better anti-pilling performance due to minimal mechanical damage.

Why Raw Materials and Equipment Define the Brushing Limit

1.Fiber Structure Matters

Cashmere fibers have an almost perfectly round cross-section and a unique hollow structure.

This gives them exceptional lightness, insulation, and natural antibacterial properties.

When fiber fineness reaches 1/50 the thickness of human hair, any rough finishing will destroy this natural “airiness.”

2. Precision Knitting Is the Foundation

Advanced finishing requires equally advanced knitting.

Compared to standard 2-needle-bed machines, Shima Seiki 5-gauge WHOLEGARMENT® technology allows far more precise loop density and tension control.

This structural stability is essential for water-wash napping, ensuring the yarn core remains strong after fibers are raised.

3. UNDYED Cashmere & Sustainability

In our UNDYED collections, we completely skip high-temperature, acidic dyeing.

Natural lanolin remains intact on the fiber surface.

Under these conditions, water-wash napping fully unlocks the natural dispersion of Tibetan cashmere fibers, delivering an ultra-light, barely-there touch while maintaining sustainability.

Our Philosophy: Brushing as a Second Life for Cashmere

For CAWOOL STUDIO, brushing is not about “more nap.”

It is about precision control — balancing soft water, time, temperature, eco-safe agents, and mechanical force — all while preserving the hollow physical structure of the fiber.

Only then can cashmere truly be reborn.
