How Italian Cashmere Is Made: From Mongolian Fiber to Luxury Knitwear

For years, I assumed that Italian cashmere was made from Italian goats. I believed that the cashmere came from Italy, that the goats grazed on Italian hillsides, and that “Made in Italy” meant “sourced in Italy.” I was wrong. The truth is more interesting.

Cashmere comes from goats that live in the harsh, high-altitude regions of Mongolia and Inner Mongolia. The raw fiber is then exported to Italy, where it is transformed into the world’s finest luxury knitwear. Italy’s true advantage is not raw materials but processing, spinning, dyeing, knitting, and finishing.

This guide will walk you through every step of the journey. From the goats in Mongolia to the mills in Biella, from the raw fiber to the finished sweater, you will learn exactly how Italian cashmere is made—and why it commands such a premium.

What Is Cashmere?

The Cashmere Goat

Cashmere comes from the Capra hircus goat, a hardy breed that has adapted to survive the brutal winters of Central Asia. These goats grow a coarse outer coat to protect against the elements and a soft, downy undercoat that provides insulation. It is this undercoat that becomes cashmere.

The goats are not domesticated in the traditional sense. They roam freely across the steppes, grazing on sparse vegetation. The harsh climate is essential to cashmere production: the goats need the cold to grow the fine undercoat.

Where Cashmere Fiber Comes From

The finest cashmere comes from specific regions where the climate is harsh enough to produce the softest undercoat.

Mongolia: The most important source of premium cashmere. Mongolian cashmere is known for its exceptional fineness and length.

Inner Mongolia: An autonomous region of China, also known for high-quality cashmere.

China: The world’s largest producer of cashmere, though quality varies significantly.

Afghanistan: A smaller but growing source of cashmere.

Iran: A minor source, but still notable.

Why Cashmere Is So Valuable

Rarity: Each goat produces only 150 to 200 grams of usable cashmere per year. It takes the fleece of three to four goats to make one sweater.

Softness: Cashmere fibers are extremely fine—typically 14 to 16 microns, compared to 25 to 30 microns for fine wool.

Warmth-to-Weight Ratio: Cashmere is eight times warmer than sheep’s wool by weight. A thin cashmere sweater can be as warm as a heavy wool sweater, but without the bulk.

Labor-Intensive Production: The fiber must be collected by hand, sorted, cleaned, and processed. Each step requires skill and time.

The Journey Begins: Sourcing Raw Cashmere Fiber

Harvesting the Fiber

Spring Molting Season: Cashmere goats naturally shed their undercoat in the spring. The fiber is collected during the molting season.

Combing vs Shearing: The highest-quality cashmere is collected by combing the goats. This is less stressful for the animals and yields longer, finer fibers. Shearing is also used but can damage the fiber.

Fiber Collection: The collected fiber is then sorted and packed for transport to mills in Italy and elsewhere.

Sorting and Grading

Once the raw fiber arrives in Italy, it is sorted and graded by experts.

Fiber Diameter: The finest cashmere is 14 to 16 microns. Coarser cashmere (18 to 20 microns) is used for lower-quality garments.

Fiber Length: Long fibers (over 36 millimeters) are stronger, more durable, and less prone to pilling. Short fibers (under 30 millimeters) are weaker and pill more.

Color Consistency: Natural cashmere ranges from white to grey to brown. Sorting separates the colors for dyeing.

Purity Assessment: The fiber is checked for contaminants and impurities.

Why Raw Material Quality Matters

The quality of the raw fiber determines the quality of the finished garment. Italian brands that prioritize quality source the finest fibers and grade them meticulously. This is the foundation of exceptional cashmere.

Why Italy Became the Global Capital of Cashmere Manufacturing

The Textile Heritage of Northern Italy

Step 1: Cleaning and Washing the Raw Fiber

The raw cashmere arrives at the mill covered in dirt, grease, and other impurities. The first step is washing.

Removing Natural Oils

Cashmere contains natural oils (lanolin) that must be removed. The washing process uses warm water and mild detergents to clean the fiber without damaging it.

Eliminating Dirt and Debris

The fiber is washed to remove dirt, dust, and other contaminants. This ensures that the cashmere is clean and pure.

Preparing Fibers for Processing

After washing, the fiber is dried and prepared for the next stage. The washing process affects the final softness of the garment.

Why This Stage Affects Final Softness

If the fiber is washed too aggressively, it can damage the cuticle and reduce softness. Italian mills have perfected the washing process to preserve the natural softness of the cashmere.

Step 2: Carding and Fiber Alignment

Carding is the process of aligning the fibers in a uniform direction.

What Carding Does

Carding separates the individual fibers, removes any remaining impurities, and aligns them in a parallel direction.

Creating Uniform Fiber Direction

The aligned fibers are then formed into a continuous strand called a sliver.

Improving Consistency

Carding improves the consistency of the fiber, ensuring that the yarn will be even and strong.

Preparing Fibers for Spinning

The sliver is then ready for spinning, the next stage in the process.

Step 3: Spinning Cashmere Into Yarn

Spinning is the process of twisting the fibers together to create yarn.

Turning Fibers Into Thread

The aligned fibers are drawn out and twisted to create a continuous thread. The twist holds the fibers together and gives the yarn its strength.

Single-Ply vs Multi-Ply Yarns

• Single-ply: One strand of yarn. Lightweight and soft but less durable.
• Two-ply: Two strands twisted together. More durable and holds shape better.
• Four-ply: Four strands twisted together. Very durable and warm.

Controlling Strength and Softness

The spinning process affects the strength and softness of the yarn. Tighter twists create stronger yarns. Looser twists create softer yarns.

Why Italian Mills Excel at Spinning

Italian mills have perfected the spinning process. They understand the relationship between twist, strength, and softness, and they adjust the process accordingly.

How Yarn Quality Affects the Finished Garment

High-quality yarn is stronger, more durable, and less prone to pilling. It holds its shape better and feels softer against the skin.

Step 4: Dyeing and Color Development

Dyeing is the process of adding colour to the cashmere.

The Importance of Dyeing Expertise

Dyeing cashmere requires expertise. The fiber is delicate, and the dye must be applied carefully to avoid damaging it.

Italy’s Reputation for Color

Italian brands are renowned for their dyeing. The colours are rich, saturated, and resistant to fading.

Dyeing Before vs After Knitting

Dyeing before knitting: The yarn is dyed before it is knitted. This allows for more consistent colour and is the most common method.

Dyeing after knitting: The finished garment is dyed. This creates a more nuanced, slightly irregular colour that some brands prefer.

How Luxury Brands Maintain Consistency

Luxury brands maintain consistency through careful control of the dyeing process. They use high-quality dyes, precise temperature control, and rigorous testing.

Why Premium Dyeing Improves Longevity

High-quality dyeing ensures that the colour does not fade, even after years of wear.

Original Perspective: Italy’s Greatest Contribution Is Not Cashmere—It’s Transformation

The Common Myth

Many consumers believe that Italy produces the world’s best cashmere. They assume that the cashmere comes from Italian goats.

The Reality

Italy rarely produces the raw fiber. The cashmere comes from Mongolia and Inner Mongolia.

Where Value Is Actually Created

Processing: Cleaning, carding, and preparing the fiber.

Spinning: Creating high-quality yarn.

Dyeing: Adding rich, durable colour.

Finishing: Brushing, softening, and perfecting the garment.

Garment Construction: Knitting and assembling the finished product.

Why This Explains the Success of Italian Luxury Brands

Italian brands have built their reputations on expertise in processing, spinning, dyeing, and finishing. They add enormous value to the raw material.

Step 5: Knitting the Garment

Knitting is the process of turning yarn into fabric.

Flat Knitting

The garment is knitted in flat panels and then sewn together. This allows for more precise shaping.

Circular Knitting

The garment is knitted in a continuous tube. This is more efficient but less flexible.

Gauge Selection

The gauge—the number of stitches per inch—determines the weight and drape of the garment. Fine-gauge knits are lightweight and elegant. Chunky knits are heavier and warmer.

Shape and Structure

The knitting process determines the shape and structure of the garment. Italian brands use precision knitting techniques to ensure consistent tension and even texture.

How Luxury Brands Achieve Consistency

Luxury brands use high-quality knitting machines and skilled operators. They inspect the fabric regularly to ensure consistency.

Step 6: Finishing the Cashmere

Finishing is the process of refining the feel and performance of the garment.

Washing and Softening

The garment is washed to remove any residual oils and to soften the fibers. Italian mills use gentle washing techniques that preserve the natural softness of the cashmere.

Brushing Techniques

Brushing raises the nap of the cashmere, creating a soft, fluffy surface. The best brands brush their cashmere without damaging the underlying fibers.

Raising the Nap

Raising the nap creates a soft, luxurious feel. The nap also traps air, providing additional warmth.

Controlling Hand Feel

The finishing process determines the hand feel of the garment. Italian brands have perfected the art of finishing, creating cashmere that is soft, warm, and luxurious.

Why Finishing Creates the Luxury Experience

The finishing process is what transforms a well-made garment into a luxury garment. It creates the softness, warmth, and elegance that define Italian cashmere.

Step 7: Quality Control and Inspection

Quality control is the final step in the production process.

Measuring Consistency

Each garment is checked for consistency in colour, texture, and construction.

Checking Construction

The seams, stitching, and shaping are inspected for quality.

Color Verification

The colour is checked to ensure it matches the specification.

Defect Detection

Any defects are identified and corrected or rejected.

Luxury Standards

Luxury brands have higher quality standards than mass-market brands. They reject garments that would pass inspection at lower-quality mills.
