Developing sustainable apparel requires more than choosing an eco-friendly fiber. Clothing brands also need to consider fabric availability, certification scope, GSM, color, garment construction, customization requirements, MOQ and production lead time.
April Su supports B2B eco apparel production and OEM/ODM development using a range of sustainable and recycled materials. Selected GRS-certified fabrics are available from stock in multiple colors, which can support faster material selection and sampling. Finished sustainable garments are made to order and require custom production based on each brand's design and specifications.
Sustainable Fabrics for Eco Apparel Production
Different sustainable materials are suitable for different garments. Material selection should therefore be based on the required hand feel, structure, performance, design and target market.
Organic Cotton
Organic cotton is widely used for T-shirts, hoodies, sweatshirts, children's clothing and other everyday apparel.
Available fabric options can vary by GSM, knitting or weaving construction, color and finishing.
Where GOTS-certified organic cotton is requested, certification should be confirmed according to the specific material supplier and certificate scope.
Recycled Polyester & Recycled Fabrics
Recycled polyester is commonly used for activewear, sportswear, outerwear and blended apparel.
We can source GRS-certified recycled fabrics, including in-stock options for selected constructions and colors. Using available fabrics can reduce the need for new fabric development and can support faster sampling and custom garment production.
Hemp & Hemp Blends
Hemp can be used alone or blended with cotton, Lyocell and other fibers to create different textures, hand feels and garment applications.
Hemp and hemp-blend fabrics can be considered for T-shirts, casualwear, shirts, dresses, trousers and other natural-fiber apparel.
Lyocell & Cellulose Fiber Blends
Lyocell is commonly selected for apparel requiring softness and fluid drape. Depending on fabric construction and blend, it can be developed for T-shirts, dresses, tops, loungewear and other fashion apparel.
Lyocell can also be blended with cotton, hemp and other fibers according to the required garment characteristics.
Linen & Natural Fiber Options
Flax-derived linen is commonly used for lightweight woven apparel such as shirts, dresses, trousers and resort wear.
Other specialty natural or bio-based materials may also be evaluated according to the design, quantity and sourcing requirements of the project.
GRS-Certified In-Stock Fabric Options
For brands developing recycled apparel, selected GRS-certified fabrics are available from stock, with multiple fabric and color options depending on current inventory.
These are fabric inventory options rather than ready-made garment stock. Finished garments are developed and produced to order according to the brand's design, measurements, construction, labeling and customization requirements.
Using an available fabric can support:
- Faster material selection
- Multiple existing color choices
- Faster sample development
- Reduced fabric development requirements
- Custom recycled apparel development
Certification documentation should always be reviewed against the specific fabric, supplier and certificate scope before making product-level sustainability claims.
In-Stock Fabrics vs Custom Fabric Development
The right sourcing route depends on the product requirements and order volume.
In-Stock Fabric Selection
When an available fabric already matches the required fiber composition, GSM, construction and color, brands can select it directly for custom garment sampling and production.
This can shorten the material sourcing stage because new fabric development may not be required. However, the finished apparel is still made to order according to the approved design and specifications.
Custom Fabric Development
Custom fabric development may be more appropriate when a project requires a specific:
- Fiber composition
- GSM or fabric construction
- Pantone color
- Surface finish
- Functional requirement
- Hand feel
Custom material development can involve different fabric MOQs and lead times, which should be evaluated before sampling.
Low MOQ Custom Eco Apparel Development
Sustainable garments are made to order rather than supplied as ready-made stock.
Custom OEM/ODM apparel generally starts from 100 pieces per style, subject to fabric, color, construction and customization requirements.
When a suitable sustainable fabric is already available from stock, brands may be able to avoid a separate custom fabric development MOQ. The garment itself, however, still proceeds through sampling, approval and custom production.
Eco Apparel OEM/ODM Development Process
A typical sustainable apparel project can include:
- Design or tech pack review
- Sustainable fabric selection
- Certification and material documentation review where applicable
- Color and GSM confirmation
- Pattern and sample development
- Printing, embroidery or private label development
- Sample approval
- Bulk production coordination
- Quality control and shipment
Sampling generally takes 7–15 days, while bulk production typically takes approximately 20–35 days after sample and material approval. Custom fabrics or complex processes may require additional time.
Sustainable Material Certification & Documentation
Certification terminology should be matched to the actual scope of the supporting documents.
Depending on the project and material supplier, available documentation may relate to standards such as GRS, GOTS, OCS or OEKO-TEX®.
A certified fabric does not automatically mean that every finished garment or every stage of production carries the same certification. For B2B sourcing, the relevant supplier certificates and material documentation should be checked for the specific project.
How to Choose Sustainable Fabrics for Your Collection
Before selecting a sustainable fabric, consider:
- Garment category
- Required fiber composition
- GSM and fabric construction
- Hand feel and drape
- Available or custom colors
- Certification requirements
- Order quantity
- Target price
- Printing or embroidery requirements
- Sampling and delivery schedule
If an existing certified fabric meets the design requirements, using an in-stock fabric option may provide a more efficient route to custom garment development. When the design requires a unique composition, construction or color, custom fabric development can be evaluated instead.
