Q1: What are the different grades of cashmere?

Cashmere is graded by fiber diameter and length:

  • Grade A: 14-15.5 microns, 36-40mm length - Finest quality, ultra-soft
  • Grade B: 15.5-17 microns, 32-36mm length - Good quality, soft feel
  • Grade C: 17-19 microns, 28-32mm length - Standard quality, slightly coarse

Inner Mongolia cashmere is considered the finest globally (14-15 microns average).

Q2: How do I verify authentic cashmere?

Burn test: Real cashmere burns slowly, smells like burning hair, leaves crushable ash. Synthetic melts and smells plastic.

Touch test: Authentic cashmere feels warm, soft, and slightly waxy. Synthetic feels cool and slick.

Price check: Genuine cashmere costs $50-150/kg for raw fiber. Suspiciously low prices indicate blends or fake.

Q3: What's the difference between cashmere and wool?
  • Source: Cashmere from goat undercoat; wool from sheep
  • Softness: Cashmere is 3x softer (14-19 vs 20-40 microns)
  • Warmth: Cashmere is 8x warmer than wool by weight
  • Weight: Cashmere is lighter and more breathable
  • Price: Cashmere costs 3-5x more than wool
  • Durability: High-quality wool lasts longer; cashmere requires more care
Q4: How should I care for cashmere fabric?

Washing:

  • Hand wash in cold water (max 30°C/86°F)
  • Use cashmere-specific or mild pH-neutral detergent
  • Never wring or twist - gently press out water
  • Lay flat to dry, reshape while damp

Storage:

  • Fold (don't hang) to prevent stretching
  • Store with cedar blocks to prevent moths
  • Avoid plastic bags - use breathable cotton
Pro Tip: Dry clean only if heavily soiled. Over-cleaning damages fibers.
Q5: Why is cashmere so expensive?

Production is labor-intensive and limited:

  • Each goat produces only 150-200g of usable fiber annually
  • One sweater requires 3-4 goats' annual production
  • Hand-combing during molting season (spring)
  • Complex processing: dehairing, spinning, weaving
  • High waste rate (up to 50% during processing)
Q6: What's the best cashmere blend ratio?
  • 100% cashmere: Maximum softness and warmth, requires careful maintenance
  • 90% cashmere + 10% silk: Added sheen and drape, good for luxury garments
  • 80% cashmere + 20% wool: More durable, better shape retention
  • 70% cashmere + 30% nylon: Enhanced durability for socks and activewear

For fabric wholesale, 85-95% cashmere offers the best balance of quality and practicality.

Q7: Where does the best cashmere come from?

Top producing regions:

  • Inner Mongolia, China: 60% of global production, finest fiber (14-15 microns)
  • Xinjiang, China: 20% of production, good quality (15-16 microns)
  • Mongolia: Premium quality, similar to Inner Mongolia
  • Afghanistan/Iran: Coarser fiber (17-19 microns), lower cost

China produces 70%+ of the world's cashmere, with Inner Mongolia being the gold standard.

Q8: How do I choose cashmere fabric weight?

Fabric weights for different applications:

  • 180-220 gsm: Lightweight scarves, linings, summer wraps
  • 220-280 gsm: Standard sweaters, cardigans, light jackets
  • 280-350 gsm: Heavy sweaters, coats, winter wear
  • 350+ gsm: Overcoats, blankets, luxury throws
Q9: Does cashmere pill? How to prevent it?

Yes, all cashmere pills initially. Quality cashmere pills less over time.

To minimize pilling:

  • Choose longer fiber cashmere (Grade A, 36mm+)
  • Avoid friction (rough bags, seatbelts, backpacks)
  • Rest garments 24-48 hours between wears
  • Use cashmere comb or fabric shaver gently
  • Turn inside out before washing
Note: Some initial pilling is normal and doesn't indicate poor quality.
Q10: What's the MOQ for cashmere fabric orders?

Typical MOQ from Chinese suppliers:

  • Stock fabric: 50-100 meters per color
  • Custom woven: 300-500 meters per design
  • Custom dyed: 200-300 meters per color
  • Sample orders: 5-20 meters (higher per-meter cost)

Lead time: 15-30 days for stock, 30-45 days for custom production.
