Allergen Resistance & Health Concerns

Down

Hypoallergenic:

No

Allergies:

Common allergen for many people. Down proteins can trigger respiratory reactions, sneezing, and congestion. Not recommended for allergy sufferers.

Dust Mites:

Can harbor dust mites if not properly maintained. Regular washing and drying helps prevent dust mite colonization.

Chemical Concerns:

Natural material with minimal chemical treatment. Look for OEKO-TEX certified down free from harmful substances.

Silk

Hypoallergenic:

Yes

Allergies:

Naturally hypoallergenic and suitable for most allergy sufferers. True silk allergies are extremely rare. The smooth, tightly-woven structure naturally resists dust mites, mold, and mildew without chemical treatments. Silk proteins (fibroin and sericin) rarely trigger allergic reactions. However, some individuals may react to residual processing chemicals or dyes - look for OEKO-TEX Standard 100 certification ensuring absence of harmful substances.

Dust Mites:

Highly resistant to dust mites due to smooth, tightly-woven fiber structure and natural protein composition creating hostile environment for mites. Studies show silk bedding harbors significantly fewer dust mites compared to cotton and synthetic materials. The low moisture retention (silk wicks rather than absorbs moisture) creates dry environment dust mites cannot thrive in. Excellent choice for dust mite allergy sufferers.

Chemical Concerns:

Natural material with minimal chemical processing when properly sourced. However, some manufacturers use harsh chemicals during degumming (sericin removal) process, or add synthetic dyes and finishes. Look for OEKO-TEX Standard 100 certification ensuring silk is free from harmful chemicals, heavy metals, and formaldehyde. GOTS certification indicates organic production. Avoid silk treated with chemical flame retardants or excessive finishing agents.

Care & Maintenance

Down

Washable:

Yes

Washing Instructions:

Machine washable on gentle cycle with mild detergent. Use low heat or air dry, adding clean tennis balls to break up clumps. Ensure complete drying to prevent mildew.

Drying Instructions:

Tumble dry on low heat for several hours. Check regularly and fluff. Must be completely dry before use to prevent mold and odor.

Maintenance Tips:

  • Fluff daily to redistribute down and maintain loft
  • Use pillow protector to prevent oils from reaching down
  • Air out regularly in sunlight (not direct) to freshen

Silk

Washable:

Yes

Washing Instructions:

Hand wash in cool water (30°C/85°F maximum) with pH-neutral silk detergent or baby shampoo. Alternatively, machine wash on delicate cycle in mesh laundry bag with silk-specific detergent. Wash every 3-7 days or more frequently for acne-prone skin. Turn inside out before washing to protect outer surface. Never wring or twist fabric.

Drying Instructions:

Air dry only by laying flat on clean towel away from direct sunlight and heat sources. Gently press out excess water with towel - never wring. Can also hang dry in shaded, well-ventilated area. Never use clothes dryer as heat permanently damages silk proteins and causes shrinkage. Allow 8-24 hours for complete drying.

Maintenance Tips:

  • Wash pillowcases every 3-7 days to remove oils, bacteria, and maintain hygiene and skin benefits
  • Use silk-specific or pH-neutral detergent - avoid harsh chemicals, enzymes, or brighteners
  • Store in cool, dry place away from direct sunlight which causes yellowing and fiber breakdown

Durability & Longevity Factors

Down

Factors Affecting Lifespan:

  • Fill power quality - Higher fill power (600+) lasts longer
  • Regular fluffing and maintenance to prevent permanent clumping
  • Proper washing and thorough drying to prevent mildew
  • Quality of shell fabric preventing down migration

Silk

Factors Affecting Lifespan:

  • Momme weight - Higher momme (22-25mm) provides superior durability and longevity
  • Quality of silk - 100% mulberry silk Grade 6A lasts longer than lower grades or blended silk
  • Washing frequency and technique - Gentle hand washing extends life; harsh machine washing accelerates breakdown
  • Quality of construction - Reinforced seams and quality stitching prevent tearing and unraveling
  • Proper storage away from direct sunlight prevents color fading and fiber degradation
  • Frequency of use and care during sleep - rough jewelry or skin can snag delicate fibers

Environmental Impact & Sustainability

Down

Sustainability:

Natural, renewable resource. However, down industry has ethical concerns regarding live-plucking and force-feeding practices. Look for RDS or DOWNPASS certification ensuring ethical sourcing.

Biodegradable:

Yes

Manufacturing:

Waterfowl farming has environmental impact. Ethical certifications ensure humane treatment. Down is a byproduct of food industry in responsible supply chains.

Silk

Sustainability:

Moderately sustainable natural material. Mulberry silk production requires cultivated mulberry trees (which sequester carbon) and silkworms. Traditional sericulture has relatively low environmental impact compared to synthetic materials. However, conventional silk production involves killing silkworm pupae inside cocoons. Peace silk (Ahimsa silk) allows moths to emerge before harvesting but is more expensive and less common. Silk is biodegradable, decomposing naturally within 1-4 years. Look for GOTS or organic certifications ensuring sustainable practices.

Biodegradable:

Yes

Manufacturing:

Silk production involves sericulture (raising silkworms), harvesting cocoons, degumming to remove sericin, spinning fibers into thread, and weaving fabric. Traditional processes are relatively low-impact. However, industrial silk production can involve harsh chemical degumming agents and synthetic dyes with environmental concerns. Ethical concerns exist regarding silkworm welfare as pupae are typically killed during harvesting. Water and energy requirements are moderate compared to synthetic materials but higher than some natural fibers.
