Sportswear Fabrics and Safety

1. What fabrics are commonly used in sportswear?

Sportswear is often made from:
Synthetic fabrics: polyester, nylon, spandex/lycra.
Natural fabrics: organic cotton, bamboo fiber, merino wool, which provide breathability, comfort, and are more eco-friendly.

2. Which harmful substances may exist in synthetic fabrics?
A. Phthalates and Bisphenol A (BPA)

Found in prints, softeners, and plastic coatings of polyester and spandex.
Classified as endocrine disruptors, linked to cancer risk and hormonal imbalance (Wikipedia, Wired).
Studies show children’s clothing often contains multiple phthalates, with exposure levels exceeding safety standards (Wikipedia).

B. PFAS (“Forever Chemicals”)

Used in waterproof, stain-resistant, and sweat-proof coatings (e.g., DWR, Gore-Tex).
Extremely persistent in the environment, bioaccumulate in humans, and linked to endocrine disorders, thyroid disruption, and cancer (FT, Wikipedia).
The EU plans a full PFAS ban by 2026, but many brands still rely on them (FT).

C. Other hazardous chemicals: Flame retardants, volatile amines, dyes

Sweat can trigger the release of plastic additives (phthalates, BPA, flame retardants) from fabrics into skin contact, raising risks to the nervous system, hormones, and even cancer (The Guardian).

3. Why are these chemicals especially concerning for sportswear?

Sportswear is worn directly against the skin, and sweat increases chemical absorption (The Guardian).
Chemicals like PFAS and phthalates can accumulate in the body, disrupting immunity, endocrine functions, and increasing cancer risk (Wikipedia).
Functional coatings (waterproof, stain-resistant) enhance performance but raise toxic residue exposure.

4. What is SAINIYA’s approach to solving these problems?

A. Fabric choices: prioritizing natural, eco-friendly fibers

Organic cotton, bamboo, merino wool are naturally breathable, moisture-wicking, and safe, without PFAS or harmful coatings (FT).
Bamboo fibers naturally provide antibacterial properties.

B. Eliminating PFAS, flame retardants, and toxic coatings

No use of PFAS or flame-retardant chemicals.
Alternatives include waxed cotton, plant-based coatings, and natural weaving structures to achieve water resistance without “forever chemicals” (FT).

C. Certified supply chains & testing

Partnerships only with suppliers certified by OEKO-TEX® and GOTS, ensuring fabrics are tested for hazardous substances (OEKO-TEX).
Transparent supply chains ensure safety from yarn spinning to dyeing and finishing.

D. Safer dyeing and printing methods

Use of plant-based or low-allergy dyes, avoiding highly allergenic disperse dyes (e.g., deep red, black).
Graphics and prints avoid heavy plasticized coatings.

E. Customer guidance

Recommend gentle washing before first wear, avoiding harsh detergents, tumble drying, or excessive friction.
Educate consumers on choosing certified organic fabrics and extending garment life.

Sample Q&A Copy for Website or Blog

Q: Why are synthetic fabrics so widely used in sportswear?
A: Polyester, nylon, and spandex offer elasticity, quick-drying, and durability—ideal for performance. But they often require chemical finishing, which may pose health risks.

Q: Which substances are the most concerning?
A: The most critical are phthalates and BPA (used in prints and softeners), plus PFAS (“forever chemicals”) in waterproof coatings. Activated by sweat, these can be absorbed through the skin and disrupt hormones or raise cancer risks (Wikipedia, Wired, FT, The Guardian).

Q: How does SAINIYA solve this?
A: SAINIYA only uses natural fabrics like organic cotton, bamboo, and merino wool—completely free of PFAS and toxic coatings. All suppliers are OEKO-TEX® or GOTS certified. We also avoid plasticized prints and allergenic dyes, instead opting for plant-based or safe dyeing methods. This ensures skin-friendly, breathable, and safe sportswear.

Q: How should I care for my SAINIYA sportswear?
A: Wash gently before first use, avoid high heat or strong detergents, and air dry naturally. This not only protects your skin but also extends garment life.
