The Magic of Mulberry Silk
From lush mulberry leaves to the exquisite sheen of silk fabric, discover the fascinating journey behind the world's most coveted luxury textile.
As premier suppliers of unprinted and undyed premium mulberry silk (Bombyx mori, 100% pure), we equip ateliers, high-volume factories, and fabric converters with specs-driven excellence. Sourced from controlled Morus alba-fed sericulture, our silk boasts fibroin beta-sheets yielding tensile strength of 4.0 -- 6.0 g/denier -- 50% superior to steel by weight—ensuring zero breakage in power looms up to 1,200 RPM.
Sericulture Precision: Mulberry's Technical Edge
Silkworms thrive on mulberry's 20–25% protein content, producing filaments with 10–14 micron diameter and uniform 13–20 denier. We spec our offerings as:
Technical tidbit: Our degumming retains 70–75% sericin for natural lubricity, cutting loom friction by 12% vs. fully degummed rivals.
Performance Metrics for Production Wins
● Moisture Regain: 11% at 65% RH—absorbs 30% more than cotton, ideal for humidity-controlled factories.
● Elongation at Break: 20–25%, preventing snaps in jacquard or dobby weaving.
● Pilling Resistance: 4–5 (ASTM D3512), post-dyeing—crucial for atelier ready-to-wear.
● Whiteness Index: >80 (CIE Lab*), perfect blank canvas for reactive or acid dyes.
Factories report 15–20% waste reduction; ateliers rave about the photonic luster from triangular cross-sections (refractive index 1.54).
Sustainability Certifications: Green from Grove to Greige
Our mulberry silk meets the highest eco-standards for B2B compliance:
● OEKO-TEX Standard 100 (Class I): Zero harmful substances, tested per batch.
● GOTS 5.0 Precursor: Organic mulberry inputs, no pesticides, <1% processing auxiliaries.
● Global Recycled Standard (GRS) Eligible: Low-water reeling (15L/kg vs. industry 30L).
● Blockchain Traceability: Farm-to-factory audits via IBM Food Trust platform.
Carbon footprint: 9.2 kg CO2e/kg—40% below tussah silk. Ideal for EU REACH, US CPSIA, and sustainable fashion labels.
Traceable Supply: From Cocoon to Your Floor
Direct from vetted farms: Boiled at 95–100°C, reeled at 300–500 m/min, skein-dyed ready. Blockchain traceability. MOQ 500kg; 4–6 week L/T.
Spec pro-tip: 20/22 denier with 1,200 TPM twist yields 120–140 ends/inch and 8–10% crimp for snag-free warps.
