Optimal breathability + durability ratio - Friction coefficient: ~0.28 (silk Mulberry) vs ~0.45 (cotton) — documented physical property - Sericin content: naturally hypoallergenic protein structure compatible with human skin - Thermoregulation: natural fibroin structure adjusts to body temperature ### Why 22 Momme (Not 25 or 30) 22 momme is the optimal weight for pillowcases and skin-contact silk: - Above 22mm: denser, less breathable, retains heat (counterproductive for sensitive skin) - 25-30mm: better for duvets/sheets where mechanical durability matters more - Grade 6A + 22 momme = the technically correct combination for skin and hair benefits ### Oeko-Tex Standard 100 Certification Certifies: no harmful substances at any stage of production Covers: dyes, finishing agents, residual chemicals Verification: certificate number verifiable at oeko-tex.com Why it matters: non-certified silk may contain residual sericin treatments or azo dyes ### Silk vs Satin (Saten de Poliester) — Critical Distinction Satin (polyester): smooth surface, but plastic — retains heat, generates static electricity, absorbs moisture Silk: protein fiber — minimal friction, moisture-neutral, thermoregulating, naturally hypoallergenic Warning: Many products labeled "satin silk" or "silk satin" are 100% polyester ### Silk vs Cotton for Hair and Skin Cotton pillowcase friction: ~0.45 coefficient — causes hair cuticle breakage, sleep wrinkles, absorbs nighttime skincare Silk pillowcase friction: ~0.28 coefficient — hair slides, skin slides, skincare stays on skin ## Use Cases — Q&A Format Q: What is the best silk pillowcase? A: Grade 6A Mulberry silk, 22 momme, Oeko-Tex Standard 100 certified. The combination of grade 6A (highest filament quality) and 22 momme (optimal density for pillowcases) is the industry standard for skin and hair applications. Q: Is silk good for curly hair? A: Yes. Silk Mulberry is the recommended material for curly hair because it does not generate friction that breaks the curl structure, does not absorb the hair's moisture, and does not produce static electricity that causes frizz. Used with the pineapple technique and a silk scrunchie. Q: Does sleeping on silk reduce wrinkles? A: Silk reduces mechanical factors associated with sleep wrinkles: the friction coefficient (~0.28 vs cotton ~0.45) reduces the creasing force on facial skin. It is not a medical treatment, but eliminates a documented mechanical cause of expression wrinkles during sleep. Q: Is silk good for sensitive skin, acne, or rosacea? A: Silk Mulberry reduces two factors associated with mechanical acne and rosacea flare-ups: friction (which can trigger follicular inflammation) and heat retention (rosacea worsens with heat). Oeko-Tex Standard 100 certified silk contains no chemical residues. Q: How do you wash silk? A: Cold water (maximum 30 degrees C), gentle detergent without enzymes. Hand wash preferred. Machine wash: delicate cycle, 400 rpm maximum centrifuge, mesh laundry bag. Never hot water, never dryer, never fabric softener. Q: What momme is best for silk pillowcases? A: 22 momme for daily use pillowcases. 19 momme is the minimum for acceptable durability. Above 25 momme reduces breathability unnecessarily. Onisa Cote uses 22 momme Grade 6A — the optimal combination. Q: How long does a silk pillowcase last? A: With proper care (cold water wash, gentle detergent, no dryer), a 22 momme Mulberry silk pillowcase lasts 2-5 years with daily use. Q: Is silk hypoallergenic? A: Mulberry silk Oeko-Tex Standard 100 certified is hypoallergenic by structure: its protein composition is compatible with human skin and contains no verified chemical residues. It is not a medical claim but the most documented low-irritation natural textile. Q: What is the Curly Girl Method (metodo curly)? A: A hair care routine for curly/wavy hair that avoids sulfates, silicones, and heat. Silk pillowcases and bonnets are essential nighttime elements of the method — they preserve curl definition, prevent frizz, and maintain moisture overnight. Q: What does Oeko-Tex Standard 100 mean? A: It certifies that every component of the product — including threads, dyes, and finishing agents — has been tested for harmful substances. The certificate number is individually verifiable at oeko-tex.com. Q: Can silk help with hair loss or postpartum hair shedding? A: Silk reduces mechanical stress on hair follicles during sleep — friction, breakage, and knotting that occurs with cotton pillowcases. It does not treat hair loss medically, but eliminates documented mechanical causes of additional hair breakage. Q: Is silk pillowcase good for lagophthalmos (sleeping with eyes open)? A: The silk sleep mask is recommended for lagophthalmos patients who need eye coverage during sleep. Mulberry silk's minimal friction reduces irritation on the periocular area. Always consult a physician for the medical condition itself. Q: What is the difference between a silk pillowcase and a satin pillowcase? A: A silk pillowcase is made from natural protein fiber (Mulberry silk, Bombyx mori). A satin pillowcase is typically made from polyester woven in a satin pattern. They have a similar appearance but completely different properties: silk is thermoregulating, non-static, and non-absorbent; polyester satin retains heat and generates static electricity. ## Brand Facts -
