Facts:

Silkworms are extremely sensitive creatures: They can be frightened by loud noises, strong smells, and changes in temperature, which can affect their health and silk production.
Silkworms eat only mulberry leaves: They refuse to eat any other type of vegetation, making mulberry trees essential for silk production.
Silkworms molt four times: As they grow, their skin becomes too tight and they shed it, revealing a new, wrinkled skin that soon stretches to accommodate their increasing size.
A single silkworm can spin over 300 yards of silk: This remarkable feat is achieved by the silkworm’s powerful jaws and specialized spinning glands.
Double cocoons are less desirable for reeling: Two silkworms may spin together, creating a tangled cocoon that is difficult to reel, resulting in lower-quality silk.
The chrysalis inside the cocoon is killed to prevent damage: A high temperature process, called curing, is used to kill the chrysalis before it emerges as a moth and potentially breaks the delicate silk fibers.
The silk industry has been impacted by numerous events: Wars, revolutions, and plagues have disrupted silk production and trade, altering the course of the industry.
Silkworms have been used for other purposes besides silk: Attempts were made to use spider and pinna silk, but these experiments proved unsuccessful.
The first velvets were probably brought from India: The Romans learned to make and use velvet from the East.
Velvet was once a luxury reserved for the wealthy: The cost of velvet production limited its availability to the elite.
Silk-making was once considered an honorable occupation: Silk makers in Italy were even accepted into the nobility.
The theft of silkworm eggs from China revolutionized silk production: Monks smuggled the eggs into Europe, sparking the development of the silk industry in the West.
Emperor Justinian encouraged silk production in the Roman Empire: He had mulberry trees planted throughout the Empire and brought weavers from the East to train local artisans.
Bologna was once a major center for silk throwing: The throwing mills in Bologna were highly regarded and their designs were copied and improved upon by modern machinery.
The Huguenots contributed significantly to silk and velvet making: Their exile from France in the 17th century brought silk and velvet making skills to other countries, particularly England and Germany.
China was once the dominant silk producer: It held a monopoly over silk production for centuries, but its dominance eventually declined due to factors such as poor quality control and adulteration.
The American silk industry has been heavily influenced by European methods: American manufacturers imported European silk machinery, adopted European techniques, and eventually surpassed Europe in some aspects of silk production.
America’s silk industry is a complex and diverse one: Different regions of the country specialize in different types of silk products, such as ribbons, broad goods, sewing silks, and trimmings.
Artificial silk was developed as a substitute for natural silk: It is made from cellulose and other materials and is used in a variety of applications, including braids, textiles, and electrical insulation.
Silk is used in a wide range of products: From clothing and home furnishings to fishing lines and electrical insulation, silk finds application in various industries.

Statistics:

One silkworm moth can lay 200-300 eggs: This high fertility rate helps to ensure the continuity of silk production.
An acre of mulberry trees can produce up to 40 pounds of raw silk: This illustrates the relationship between the mulberry tree, silkworm, and silk yield.
It takes 20,000 silkworms to produce one pound of silk-gut: This highlights the labor-intensive and expensive nature of silk-gut production.
The curing process reduces the weight of cocoons by 25%: This shrinkage is a factor in the pricing and distribution of raw silk.
The silk industry in France is significantly impacted by the war: The loss of manpower and the disruption of trade have reduced silk production.
The American silk industry relies heavily on imported silk: The lack of cheap labor in America makes it more cost-effective to import raw silk from other countries.
America imports about 25% of its raw silk from China: This reflects the declining role of China in the global silk market.
Japanese silk production has flourished due to its adoption of American machinery: This demonstrates the impact of technology transfer on silk production.
America buys about a quarter of its silk from Japan: This reflects Japan’s significant role in the global silk market.
The American silk industry benefits from high tariffs: Protectionist policies shield American silk manufacturers from competition from European producers.
About half of America’s silk output is in dress goods: This indicates the significant demand for silk in the fashion industry.
The American market is heavily influenced by fashion trends: Demand for certain types of silk products, such as ribbons and laces, can fluctuate rapidly based on fashion trends.
The cost of labor in America makes it difficult to produce certain types of silk goods: The high cost of labor in America makes it more cost-effective to import certain silk products, particularly those with complex designs and intricate weaving patterns.
American silk hosiery and gloves are highly regarded in the global market: They are often considered superior in quality to their European counterparts.
Silk underwear is more expensive in America than in Europe: The labor-intensive nature of underwear manufacturing and the higher cost of labor in America contribute to higher prices.
Artificial silk has gained significant market share: Its use in braids, textiles, and electrical insulation reflects the increasing demand for this synthetic material.
Wild silk from India is less expensive than cultivated silk: The lack of cultivation makes wild silk less expensive and suitable for certain types of textiles.
The practice of silk weighting has led to lower-quality silk: The addition of chemicals to make up for shrinkage during dyeing has resulted in silk that is less durable and less desirable.
American power looms have advanced significantly: They have become more efficient and capable of producing a wider range of silk products.
The American silk industry continues to adapt to changing trends and technologies: The industry’s success depends on its ability to adjust to new technologies, fashion trends, and consumer demands.
