Recycled Polyester Staple Fibre (RPSF) is being increasingly applied in textile applications where sustainability and material performance need to go hand in hand. A particular area attracting attention is baby and infant products, including clothing, bedding, soft toys, blankets and other textile items.
But when recycled polyester is used in products for babies, sustainability is not enough. The material must also meet rigorous safety standards. That’s where OEKO-TEX® STANDARD 100, Product Class I, comes into play.
Product Class I has the strictest requirements and limit values within STANDARD 100 and is intended for products for babies and children up to 36 months.
The Need for Safer Infant Products in Textiles
Babies have a more sensitive skin and can be in contact with textiles for long periods. Chemical safety is an important consideration in the choice of textile materials as infant products can also come in contact with the mouth.
OEKO-TEX® STANDARD 100 checks textiles and textile components for harmful substances. Its testing framework covers over 1,000 substances, with the requirements becoming more stringent depending on intended use and the level of skin contact.
For manufacturers who use recycled polyester, this provides an extra level of assurance that the material can be used in applications where the safety requirements are especially high.
What’s different about recycled fibre?
Post-consumer PET bottles and other recovered polyester products can be used to make recycled polyester. Unlike virgin polyester, recycled materials have had a previous life, so their origins and processing can vary.
OEKO-TEX specifically takes these additional considerations into account. The recycled materials within the scope of certification require information on the material source, an effective quality management system must be demonstrated, and testing requirements may differ from virgin materials.
This is why quality control is especially important when recycled fibre is used in sensitive applications such as baby textiles.
Why RPSF is Concerned with Class I
OEKO-TEX STANDARD 100 can include materials at different stages of production, like fibres, yarns, fabrics and finished articles.
That matters for an RPSF manufacturer, because the fibre itself may be part of the safety and compliance chain before it reaches a yarn spinner, a fabric manufacturer or a baby-product brand.
A Class I certified fibre instills more confidence for downstream manufacturers when considering their material sourcing. It also provides buyers with documented proof that the certified material has been checked against the relevant OEKO-TEX requirements.
Certification: More Than Recycling
It is important to distinguish two different claims: recycled content and chemical safety.
A recycled-content certification or chain-of-custody system can help show where recycled material comes from and how it moves through the supply chain. The OEKO-TEX STANDARD 100 answers a different question: has the certified textile article or material been tested for harmful substances according to the relevant product class?
OEKO-TEX also has specific rules for recycled materials, including source details and quality-management requirements.
Collectively, these approaches can provide a more resilient basis for responsible recycled textile production.
What This Means for Baby Textile Manufacturers
Brands that produce infant clothing, blankets, bedding, toys or other textile products must take into account the safety requirements of the end use, not just the fact that a fibre is recycled.
They should consider:
- The end use of the final product
- OEKO-TEX product class required
- Scope of certification of supplied fibre
- Dyes, finishes and other processing chemicals
- Other textile components and accessories
- Traceability and Documentation of Supplier Quality
A valid fibre certificate is not the same as certification of each finished baby product. It is important to consider the scope of certification and the components of the finished article.
Why This Is More Important in 2026
The new OEKO-TEX Regulations 2026 with revised test criteria, limit values and requirements will be applied after a transition period from June 1, 2026.
For RPSF manufacturers catering to the baby-textile segment, it is important to stay abreast of the updated requirements to sustain buyer confidence and promote long-term international business.

The Future of Safe Recycled Polyester
Simply increasing the amount of PET waste that gets recycled is not the future of recycled polyester. It is also about making consistent, traceable and properly tested materials for demanding applications.
One particularly important reference point for baby products is OEKO-TEX STANDARD 100 Product Class I, which includes the most stringent requirements for products intended for babies and toddlers.
The next generation of recycled textile products will be better supported by RPSF manufacturers who focus on quality systems, responsible sourcing and relevant certifications, as brands increasingly blend sustainability with higher expectations for product safety.
