Bamboo Viscose Spandex Fabric for Leggings
-- Steady & Reliable Manufacturer --
Overview
Our bamboo viscose spandex fabric for leggings is engineered for activewear and casualwear buyers who need a four-way stretch knit that delivers opacity, skin comfort, and certified sustainable fiber content in one material. Made from viscose derived from organically grown bamboo blended with spandex, this fabric is available with OCS and OEKO-TEX® Standard 100 certification — supporting brand compliance requirements in the USA, Europe, and key Asian retail markets. We offer full OEM and ODM collaboration, flexible weight and composition options, and custom color development from a single certified B2B supplier.
Introduction
This fabric combines viscose derived from organically grown bamboo with spandex elastane in a four-way stretch single jersey or interlock construction, specifically developed for fitted leggings applications. The bamboo viscose component produces a fine, smooth yarn surface that achieves adequate opacity at standard leggings weights — typically eliminating the need for a liner layer and lowering garment construction cost for clothing factories. The spandex is selected and tested for consistent elongation and recovery through repeated wear and washing, maintaining leggings shape and waistband integrity through the commercial lifecycle of the garment.
We supply this fabric to global activewear brands, yoga leggings developers, compression garment manufacturers, private-label casualwear programs, and clothing factories producing certified organic activewear collections. Whether you are sourcing a base fabric for a new leggings line, replacing an existing fabric with a certified organic alternative, or scaling a sustainable activewear range for major retail buyers, our team provides end-to-end support — from fabric specification and sample development through to bulk production with full certification documentation.

Application
- Yoga and Studio Leggings: The soft bamboo viscose surface and four-way stretch construction are well suited to fitted yoga and studio leggings where skin comfort, freedom of movement, and a premium fabric feel are primary buyer criteria. Available at 200–220 gsm for a lightweight, breathable build or 240–260 gsm for improved opacity and body.
- Compression and Sports Tights: Higher spandex ratios (12–20%) are available for compression leggings and sports tights requiring greater recovery force and a firmer fit profile. Interlock construction is recommended for additional fabric stability under tension.
- Everyday Athleisure Leggings: Mid-weight single jersey (200–230 gsm) in standard 92/8 composition is widely used for everyday casual leggings in private-label and basics collections — offering a soft, skin-friendly alternative to conventional polyester spandex at competitive production cost.
- Maternity Leggings: The gentle four-way stretch, smooth hand feel, and OCS-certified organic bamboo fiber make this fabric appropriate for maternity leggings brands where material provenance and skin safety are communicated to end consumers as key purchase drivers.
- Children's and Junior Leggings: OEKO-TEX® Standard 100 certification confirms compliance with restricted substance standards required by children's product categories across major retail markets in the USA, Europe, and South Korea.
- Certified Sustainable Activewear: For brands building certified organic activewear lines and requiring OCS transaction certificates at the fabric level, we provide full documentation with every order from our independently audited, end-to-end certified supply chain.
Advantage
- OCS-Certified Organic Bamboo — Pioneer Manufacturer: We are one of the first manufacturers globally to adopt the OCS label for organic bamboo viscose products. OCS transaction certificates are issued with every certified order, covering the full supply chain from bamboo raw material sourcing through spinning, knitting, and dyeing. This is an audited, third-party verified process — not a self-declared claim — supporting certified organic product labeling in the USA, Europe, and Australia.
- Opacity Without a Liner Layer: The fine bamboo viscose yarn and tight knit structure achieve sufficient opacity at 200 gsm and above in single jersey, and 180 gsm in interlock — eliminating the need for a separate liner in most leggings applications. This directly reduces garment bill-of-materials cost and simplifies construction for clothing factories, improving margin at the same retail price point.
- Consistent Stretch and Recovery: The spandex component is specified and tested for a minimum of 50 domestic wash cycles without significant loss of elongation or recovery force, maintaining leggings silhouette and waistband integrity through the full consumer lifecycle of the garment — reducing quality returns and brand reputational risk for buyers.
- Dope Dyeing for Documented Sustainability: Available on selected production runs, dope dyeing integrates pigment into the bamboo viscose fiber at the extrusion stage — saving approximately 60 tonnes of water per tonne of fabric, reducing dye and auxiliary chemical use by 150 kg, and cutting CO₂ emissions by around 750 kg per tonne. These are measurable, supplier-documented savings for brand sustainability reports and product-level environmental claims.
- Broad Weight and Composition Range: From 180 gsm single jersey for lightweight summer activewear to 260 gsm interlock for heavier compression applications, with spandex ratios from 5% to 20% — allowing brands to develop a complete leggings fabric range within a single certified bamboo viscose supply chain, reducing supplier complexity and streamlining certification management.

FAQ
- Q: What spandex percentage is recommended for yoga leggings versus compression tights?
- For yoga and studio leggings, 8–12% spandex in single jersey provides sufficient four-way stretch and a soft, comfortable hand feel. For compression tights requiring greater recovery force and a firmer fit profile, we recommend 15–20% spandex in interlock construction. Our technical team can advise on the right specification based on your target performance requirements when you submit your inquiry.
- Q: Can you provide OCS transaction certificates with each fabric order?
- Yes. OCS transaction certificates are issued as standard with every certified organic bamboo viscose order. Our supply chain is independently audited end-to-end and we maintain continuous OCS certification — not batch-by-batch approval — providing consistent documentation quality across both development samples and bulk production. Please specify your documentation requirements at the time of inquiry.
- Q: At what weight does this fabric provide adequate opacity for unlined leggings?
- In our standard 92/8 bamboo viscose spandex single jersey, 200 gsm and above typically provides sufficient opacity for unlined leggings. In interlock construction, 180 gsm is generally adequate. We recommend requesting a pre-production physical sample for your own opacity assessment before confirming bulk specifications, as lighter colors may require higher weights for equivalent coverage.
- Q: Is dope-dyed bamboo viscose spandex available for this fabric?
- Yes. Dope dyeing is available on selected production runs, integrating color into the bamboo viscose fiber at the extrusion stage. This saves approximately 60 tonnes of water per tonne of fabric, reduces dye and auxiliary chemical use by 150 kg, and cuts CO₂ by around 750 kg per tonne — figures that can be included in product-level environmental claims and brand sustainability reports. Color range and lead times differ from conventional dyeing; please share your color references at inquiry stage.
- Q: Can the fiber composition be customized for private-label programs?
- Yes. We support full OEM and ODM collaboration on fiber composition, fabric weight, construction type, width, and color. Spandex ratios from 5% to 20% are available across both single jersey and interlock constructions, and custom colorways can be developed with your Pantone references or physical color samples. Fabric communication is completed within 3 days and development samples are delivered within 15 days of specification confirmation.
