What Is 6A Mulberry Silk?

6A Mulberry silk refers to the highest grade and quality of silk produced from the cocoons of the Bombyx mori silkworm, which feeds exclusively on mulberry leaves. "6A" is the top rating in the silk grading system, indicating:

• Exceptional fiber length – Long and uniform silk threads
• Superior purity – Free of impurities and defects
• High tensile strength – Durable yet ultra-soft

This silk is prized for its luxurious feel and remarkable longevity, making it ideal for sensitive skin and premium products like bedding, fashion garments, and sleep accessories.

Understanding the Silk Grading System (A, B, C & 1A–6A)

Silk is graded based on quality and thread consistency. There are two grading scales:

1. Letter Grade Scale (A, B, C):

• A-grade: The finest silk, with long, smooth, and uniform threads
• B-grade: Mid-range quality with shorter or slightly uneven threads
• C-grade: Coarse or recycled silk, often used for budget textiles

2. Numerical Scale (3A to 6A):

• 3A: Entry-level pure silk—moderately refined
• 4A–5A: High-quality silk suitable for most garments and bedding
• 6A: Top-tier silk—maximum purity, strength, and softness

Only a small percentage of silk produced globally meets the 6A standard.

Benefits of 6A Mulberry Silk

1. Hypoallergenic and Skin-Friendly

• Natural protein fibers repel dust mites and allergens
• Suitable for sensitive or acne-prone skin

2. Anti-Aging Properties

• Reduces friction on delicate facial skin
• Helps prevent fine lines and sleep creases

3. Thermoregulating

• Adjusts to body temperature—cool in summer, warm in winter

4. Moisture Retention

• Unlike cotton, silk doesn’t absorb natural skin oils, keeping skin hydrated overnight

5. Long-Lasting

• Durable and fade-resistant when properly cared for

• Tussah Silk: Wild silk with shorter fibers; coarser texture
• Habotai Silk: Lightweight and smooth, but not as durable
