Chinese Silk Fabric — Frequently Asked Questions

What are the main types of Chinese silk fabric?
Chinese silk comes in several distinct varieties. Mulberry silk (sang si) is the finest and most common, produced by Bombyx mori silkworms fed exclusively on mulberry leaves. Habotai (or china silk) is a lightweight plain-weave mulberry silk used for linings and scarves. Charmeuse has a satin weave on one side and matte on the other, prized for evening wear. Shantung (also called wild silk or tussah) has a nubby texture from double cocoons. Brocade (jin) features raised patterns woven with metallic threads and is the traditional choice for ceremonial garments. Crepe de chine has a slightly crinkled surface with excellent drape. Each type has ideal applications — brocade for opera costumes, charmeuse for cheongsam dresses, habotai for martial arts sashes.
How can I tell if silk is real or synthetic?
Several reliable methods distinguish real silk from polyester imitations. The burn test is the most definitive: real silk burns with a small flame and smells like burning hair, leaving a crumbly black ash that crushes to powder. Polyester melts into a hard plastic bead with an acrid chemical smell. The touch test: real silk feels cool to the skin initially then warms up, while polyester stays warm from the start. The luster test: genuine silk has a subtle sheen that shifts color as you move it under light, whereas synthetic silk has an overly bright, uniform shine. The ring test: real silk makes a rustling sound like walking on snow when squeezed. For quick in-store checking, rub the fabric — real silk generates slight warmth through friction, polyester does not.
What is the difference between mulberry silk and wild silk?
Mulberry silk accounts for roughly 90% of global silk production and comes from domesticated Bombyx mori silkworms raised on mulberry leaf diets. The fibers are long (up to 900 meters per cocoon), smooth, and uniform in color — typically white or cream. Wild silk (tussah) comes from various wild moth species (Antheraea pernyi, Antheraea assama) that feed on oak, castor, or other leaves. Wild silk fibers are shorter (300–500 meters), thicker, and naturally tan or brownish. The resulting fabric has a rougher hand and more texture. Mulberry silk costs 2–3 times more than wild silk and is the standard for high-end garments. Wild silk's durability makes it popular for upholstery, martial arts uniforms, and structured garments where body is preferred over drape.
What does silk momme mean and what's a good weight for garments?
Momme (pronounced 'mommy' and abbreviated 'mm') is the Japanese unit for silk weight — one momme equals 3.75 grams per square yard. Lightweight silks range from 4–8 momme (good for linings, scarves, and sheer blouses). Medium weight silks at 12–16 momme are the sweet spot for most garments — charmeuse dresses, silk pajamas, and lightweight robes fall in this range. Heavyweight silks at 19–30 momme work for structured pieces like suits, wedding dresses, and ceremonial costumes. For comparison, a standard cotton T-shirt is roughly equivalent to 5–7 momme in weight. Anything below 4 momme is considered gossamer and tears easily. When buying silk fabric for costuming, 16–19 momme is the professional standard — light enough for movement but substantial enough to hold embroidery.
How should I wash and care for Chinese silk fabric?
Hand washing in lukewarm water (30°C maximum) with a gentle detergent is the safest approach. Use a silk-specific wash or baby shampoo — never regular laundry detergent, which strips silk's natural proteins. Avoid soaking for more than 5 minutes. Gently agitate, rinse in cool water, and roll in a towel to remove excess moisture. Never wring, twist, or use a dryer. Iron on low heat while slightly damp, using a pressing cloth between iron and fabric. For stubborn wrinkles, hang in a steamy bathroom. Dry clean only if the garment has structured elements or heavy embroidery — the dry cleaning chemicals can actually weaken silk fibers over time. Store folded with acid-free tissue, never on wire hangers which create shoulder points. Cedar or lavender sachets deter moths naturally.
What is Chinese silk brocade (jin) and why is it special?
Chinese brocade (duan jin or zhuanghua jin) is a richly patterned silk fabric where the design is woven into the material itself using supplementary weft threads, often in gold or silver. Unlike printed patterns, brocade patterns survive decades of wear without fading. The most famous varieties include Nanjing Yunjin (Cloud Brocade), which has been produced for over 1,600 years and requires a wooden drawloom operated by two weavers — one above and one below. A single inch of Yunjin can take 2–3 hours to weave. Sichuan Shu brocade is another storied variety dating to the Han Dynasty. Suzhou brocade is known for floral patterns and lighter weight. Brocade is the go-to fabric for Beijing opera costumes, wedding qipao, and temple decorations. Expect to pay $40–120 per meter for machine-woven brocade and $200 + per meter for handwoven pieces.
How long does Chinese silk fabric last?
With proper care, high-quality mulberry silk outlasts most fabrics. Archaeological evidence from the Han Dynasty (206 BCE–220 CE) tombs shows well-preserved silk garments over 2,000 years old, demonstrating the fiber's inherent durability. In practical modern use, a well-maintained silk garment lasts 15–25 years of regular wear. Silk's natural protein structure makes it resistant to mildew, dust mites, and many bacteria — which is why silk pillowcases are recommended for allergy sufferers. The main enemies of silk are direct sunlight (causes fading within months), perspiration (degrades fibers through acidity), and improper storage (creates permanent creases). Silk's tensile strength actually exceeds that of steel of the same diameter, making it one of the strongest natural fibers available.
Is Chinese silk fabric suitable for people with sensitive skin?
Yes — silk is widely recommended for sensitive skin conditions. Its smooth fiber structure (unlike wool's scales) doesn't irritate skin, making it hypoallergenic by nature. Silk contains 18 amino acids that are also present in human skin, which is why dermatologists often recommend silk pillowcases and bedding for eczema and rosacea patients. Silk is also naturally temperature-regulating, keeping you cool in summer (its low thermal conductivity) and warm in winter (trapping air between fibers). It absorbs up to 30% of its weight in moisture without feeling damp, which helps prevent skin irritation from sweat. For garment use, choose habotai or charmeuse with less than 15 momme for the softest feel against skin. Avoid heavily sized or stiffly woven brocades for direct skin contact.
How much Chinese silk fabric do I need for a traditional Chinese garment?
Fabric requirements depend on the garment type and your measurements. A standard qipao (cheongsam) for an adult requires 2.0–2.5 meters of 110 cm-wide fabric. A full-length silk robe (changpao) needs 3.0–3.5 meters. A martial arts tang suit (tangzhuang) takes about 2.5 meters. Children's qipao or kung fu suits need 1.2–1.8 meters. Always add 10–15% extra for pattern matching if using brocade or jacquard — this ensures the pattern aligns at seams. For pleated or gathered designs, add another 0.5 meters. When buying from China-Cart.com, each garment listing specifies the exact fabric quantity used, and we offer fabric-by-the-meter for DIY projects starting at $15/meter for habotai and $45/meter for brocade.
