For something so light against the skin, silk carries an extraordinary weight of history. Where does silk come from, not just as a fibre, but as an idea, a trade route, a civilisation-shaping material? The answer begins over five thousand years ago in the river valleys of ancient China, winds through the bazaars of Byzantium, crosses the Alps, and arrives, ultimately, at the lakeside workshops of Como, where the tradition of weaving silk into something transcendent continues to this day. At Lorenzi Como, this is not merely heritage we reference; it is heritage we practise, thread by thread, on the same shores where Italian sericulture found its finest expression.
Understanding the silk origin story is essential for anyone who values what they wear. It transforms a fabric from commodity into culture.
The ancient origins of silk: China and the birth of sericulture
The history of silk begins, as most scholars agree, around 3630 BCE in the Yangshao culture of Neolithic China. Legend attributes the discovery to Empress Leizu, who is said to have watched a silkworm cocoon unravel in her tea. Whether myth or history, the moment captures something true: silk was not invented so much as observed, a gift of nature that required human patience to unlock.
The silkworm and its secret
The creature at the centre of this story is Bombyx mori, the domesticated silk moth. Unlike its wild cousins, Bombyx mori has been selectively bred for millennia; it can no longer fly, can barely see, and exists solely to spin. A single silkworm produces a cocoon from one continuous filament of raw silk, sometimes exceeding 900 metres in length. This filament, finer than a human hair, is composed of fibroin protein coated in a gummy substance called sericin.
The silk production process, known as sericulture, follows a rhythm that has changed remarkably little since antiquity:
- Silkworm eggs are kept at controlled temperatures until hatching
- Larvae feed exclusively on fresh mulberry leaves for approximately 35 days
- The mature silkworm spins its cocoon over three to four days, moving its head in a figure-eight pattern
- Cocoons are harvested and sorted by quality, colour and size
- The sericin is softened through careful heating, allowing the filament to be reeled onto a bobbin
- Several filaments are twisted together to form a single thread of raw silk
This process, from egg to thread, is what gives silk its unmatched qualities: a natural lustre that no synthetic can replicate, a tensile strength that rivals steel by weight, and a capacity to absorb dye that produces colours of extraordinary depth and vibrancy.
China's monopoly and the penalty of death
For nearly three thousand years, China guarded the secret of how silk is made with lethal seriousness. The penalty for smuggling silkworm eggs or mulberry seeds beyond the empire's borders was death. Silk became not only a fabric but a currency, a diplomatic instrument, and eventually the commodity that gave its name to the most consequential trade network in human history: the Silk Road.
The Silk Road was never a single road but a web of overland and maritime routes connecting Chang'an (modern Xi'an) to the Mediterranean. Along these paths, silk moved westward while gold, glassware and ideas moved east. The fabric that arrived in Rome was so prized that the Senate repeatedly attempted to ban its use, fearing both the drain on the treasury and the moral softening they believed it encouraged.
How silk travelled to Europe
The Chinese monopoly on silk origin and production held until roughly the sixth century CE, when, according to the account of the historian Procopius, two Nestorian monks smuggled silkworm eggs to Constantinople hidden inside hollow bamboo canes. Whether this specific story is accurate matters less than the outcome: by the Byzantine era, sericulture had established itself in the eastern Mediterranean.
From Byzantium to the Italian peninsula
The knowledge of silk production moved westward through the Islamic world and into Sicily under Norman rule in the twelfth century. Roger II of Sicily forcibly relocated silk weavers from Greece to Palermo, establishing the first significant European silk industry. From Sicily, the craft migrated northward, to Lucca, Florence, Venice and, crucially, to the foothills of the Alps.
Como's emergence as Europe's silk capital
It was in the fifteenth and sixteenth centuries that the silk fabric history of Como truly began. The region offered everything sericulture demanded: a mild, humid microclimate tempered by the lake, abundant mulberry groves on the surrounding hillsides, and an endless supply of clean, soft water from Alpine streams, essential for dyeing and finishing.
By the seventeenth century, Como had surpassed Lyon as Europe's foremost centre of silk production. The industry was not merely transplanted here; it was refined, elevated, made into something distinctly lacustrine. The weavers of Como developed techniques for jacquard weaving, yarn-dyeing and finishing that remain benchmarks today. For a deeper exploration of this transformation, our essay on the history of the tie in Como traces the parallel evolution of Como's silk craft and its neckwear tradition.
The modern Como silk industry
Today, the province of Como accounts for roughly 80 percent of European silk production and an even greater share of the continent's finest silk finishing. The industry encompasses the full chain: throwing (twisting raw silk into yarn), warping, weaving, printing, dyeing and finishing, all within a radius of thirty kilometres around the lake.
What makes Como silk different
The question of where does silk come from has, in the twenty-first century, become inseparable from the question of where silk is finished. The vast majority of the world's raw silk is now produced in China, India, Uzbekistan and Brazil. What distinguishes Como is not the origin of every raw thread but what happens to that thread once it arrives.
Como's advantage lies in three areas:
- Dyeing expertise: the mineral composition of lake water, combined with centuries of accumulated knowledge, produces colours of a saturation and permanence that industrial dyeing cannot match. A Como-dyed navy holds a depth that distinguishes it immediately from its mass-produced equivalent
- Weaving precision: the district retains a concentration of jacquard looms, both vintage and modern, operated by artisans whose families have woven silk for generations. The tension, the density, the hand of the finished cloth are all governed by human judgement
- Finishing mastery: the final stages of silk production, including washing, calendering and hand-rolling, determine how a fabric drapes, catches light and ages. Como's finishers are among the last in the world to practise these steps by hand at scale
For those curious about how Como silk compares to silk from other Italian regions, our detailed analysis of Como silk vs Italian silk explores these distinctions further.
The craft of weaving at Lorenzi Como
At Lorenzi Como, the relationship with silk is not abstract. Our handcrafted silk ties are woven and finished in workshops along the lake's western shore, using silk that has been dyed and prepared by artisans we have worked with for years. The weaving process for a single tie involves selecting the appropriate yarn weight, setting the jacquard loom to the precise pattern, and weaving at a tension that produces the correct drape without sacrificing structure.
Our seven-fold construction represents perhaps the purest expression of what Como silk can achieve. A seven-fold tie uses a single square of silk, folded seven times upon itself without interlining. It demands a fabric of sufficient weight, density and suppleness, qualities that only properly finished Como silk reliably provides. The full process is detailed in our guide to Como silk tie weaving.
How is silk made today: the full journey of a thread
To understand silk fully, it helps to follow a single thread from cocoon to cloth.
The journey begins at a sericulture farm, typically in southern China or northeast India, where silkworms are reared in controlled environments and fed fresh mulberry leaves until they spin their cocoons. The cocoons are then sorted; only the finest, most uniform specimens are selected for reeling. Heat is applied to soften the sericin binding, and the filament is carefully unwound. Several filaments are twisted together to create a yarn strong enough to weave.
This raw silk yarn is then shipped to Como, where it enters a second life:
- Throwing: the yarn is twisted to the specifications required by the intended weave (tighter for twill, looser for satin)
- Warping: thousands of threads are aligned in parallel on a beam, ready for the loom
- Weaving: the weft thread is passed through the warp on a jacquard loom, creating the pattern and structure of the cloth
- Dyeing and printing: depending on the design, the fabric is piece-dyed, yarn-dyed or screen-printed using techniques specific to Como
- Finishing: the fabric is washed, steamed, pressed and inspected by hand before being cut and sewn
Each stage introduces variables that affect the final product. This is why two ties made from ostensibly identical silk can feel entirely different; the craft is in the decisions made at every step.
Environmental and ethical considerations
Silk is a natural, biodegradable fibre with a significantly lower environmental footprint than most synthetics. A silk tie, properly cared for, will outlast a dozen polyester equivalents, making it, paradoxically, the more sustainable choice despite its higher initial cost.
That said, the silk industry is not without ethical questions. Conventional silk production requires the cocoon to be heated before the moth emerges, which raises concerns for those attentive to animal welfare. Peace silk (also known as Ahimsa silk), which allows the moth to emerge before the cocoon is processed, offers an alternative, though the resulting filament is shorter and the fabric less lustrous.
At Como, the emphasis has increasingly shifted toward traceability and responsible sourcing. The best producers maintain direct relationships with their yarn suppliers, audit working conditions, and invest in water treatment systems to minimise the environmental impact of dyeing. The question of where does silk come from is, today, as much an ethical question as a geographical one.
A thread that connects millennia
Silk is one of the very few materials whose story spans the entirety of recorded civilisation. From the mulberry groves of ancient China to the jacquard looms of Lake Como, it has been traded, coveted, regulated and refined across five thousand years and ten thousand kilometres. It has clothed emperors and revolutionaries, furnished palaces and ateliers, and inspired artists from the Tang dynasty to the Italian Renaissance.
To wear silk, particularly silk that has been woven and finished in Como, is to participate in that continuity. It is not nostalgia; it is a living tradition, sustained by artisans who understand that the value of silk lies not in its rarity but in the care with which it is transformed from a caterpillar's thread into something worthy of the human form.
FAQ
Which country produces the most silk?
China produces approximately 80% of the world's raw silk. India is the second-largest producer, followed by Uzbekistan and Thailand. For finished luxury silk products like ties, Italy - particularly the Como region - is the leading producer.
How is silk made?
Silk is produced by silkworms (Bombyx mori) that spin cocoons of continuous silk filament. The cocoons are harvested, softened in hot water, and unwound to extract the raw silk thread. Multiple filaments are twisted together to create yarn, which is then woven into fabric.
Why is Como famous for silk?
Como has been the centre of European silk production since the 15th century. The region's humid microclimate, proximity to mulberry groves for silkworms, and generations of artisan knowledge created an unmatched ecosystem for silk weaving, dyeing, and finishing.
