| Knitted Mulberry Silk Fabric typically weighs between 100 and 220 grams per square meter depending on knit structure, is significantly more breathable than cotton knit due to silk fiber's natural moisture wicking and thermoregulating properties, and is most commonly certified under OEKO-TEX Standard 100 along with Global Organic Textile Standard for buyers requiring organic sourcing verification. |
Weight Range of Knitted Mulberry Silk Fabric
Fabric weight determines both drape and end use, and knitted mulberry silk spans a wider range than woven silk because knit structures vary from open jersey to dense interlock.
| Knit Structure | Typical Weight | Common Use |
| Single jersey silk knit | 100 to 130 grams per square meter | Lightweight t-shirts, undergarments |
| Silk rib knit | 140 to 170 grams per square meter | Fitted tops, base layers |
| Interlock silk knit | 170 to 220 grams per square meter | Sweaters, outerwear linings |
Mills producing knitted mulberry silk generally hold weight tolerance within plus or minus 5 percent of the specified gram per square meter figure, which matters for buyers matching fabric to a fixed garment specification.
Knitted Mulberry Silk Versus Cotton Knit
Buyers frequently compare these two fibers because both are used in next-to-skin garments, but their performance differs across several measurable categories.
- Natural protein fiber with a smooth, low-friction surface
- Absorbs up to 30 percent of its weight in moisture while feeling dry to the touch
- Naturally thermoregulating, cooler in summer and insulating in winter
- Higher cost per meter, generally 3 to 5 times cotton knit pricing
- Cellulose fiber with a textured surface, more prone to pilling
- Absorbs moisture but retains dampness longer against the skin
- Less temperature adaptive across seasonal wear
- Lower cost, more accessible for high-volume basics production
Blended fabrics combining silk and cotton in ratios such as 70 percent silk to 30 percent cotton are increasingly used to balance silk's comfort properties with cotton's durability and lower cost.
Why Mulberry Silk Fabric Is Breathable
Breathability in mulberry silk comes down to the fiber's triangular cross-sectional structure, which allows air and moisture vapor to pass through the fabric rather than becoming trapped.
- The triangular fiber shape reflects light differently than round fibers, contributing to silk's characteristic sheen while also creating micro air channels within the knit.
- Silk fiber absorbs moisture internally without feeling wet on the surface, keeping skin contact dry during activity or sleep.
- Open knit constructions such as single jersey further increase airflow compared to tightly woven silk fabric of similar weight.
- Silk's low thermal conductivity means it does not pull heat away from the body as quickly as synthetic knits, supporting comfort across a wider temperature range.
This combination is why knitted mulberry silk is frequently specified for sleepwear, base layers, and warm-weather apparel where sustained skin contact and moisture management both matter.
Certifications Required for Mulberry Silk Knit Fabric
Buyers sourcing knitted mulberry silk for retail or export markets typically request one or more of the following certifications, depending on the target market and sustainability claims being made.
| OEKO-TEX Standard 100 | Confirms the finished fabric is tested for harmful substances and safe for skin contact. |
| Global Organic Textile Standard | Required when silk is marketed as organic, verifying the sericulture and processing chain. |
| Responsible Wool and Silk sourcing audits | Increasingly requested by European retailers for supply chain traceability. |
| ISO 9001 mill certification | Confirms consistent quality control at the manufacturing facility rather than the fiber itself. |
Buyers working with European or North American retail partners should confirm certification validity dates directly with the mill before placing bulk orders, since OEKO-TEX certification requires annual renewal.
Choosing the Right Knit Weight for Your Product
Matching fabric weight to garment type prevents both durability problems and unnecessary material cost.
| Sleepwear and loungewear | 100 to 140 grams per square meter for a light, drapey feel |
| Everyday tops and base layers | 140 to 180 grams per square meter for durability with softness |
| Sweaters and outerwear components | 180 grams per square meter and above for structure and warmth |
