Trench Coat Fabric Guide: Common Harmful Chemicals and SAINIYA’s Healthy Solutions

A trench coat is not only a timeless fashion piece but also a practical wardrobe essential. However, during fabric production, some harmful chemicals may be hidden in the process, posing risks to your skin and overall health. If you’re looking for a safe and healthy trench coat, understanding fabric composition and toxic substances is crucial.
This article will explore common trench coat fabrics, highlight two of the most concerning harmful chemicals, and explain how SAINIYA provides safe and eco-friendly solutions for consumers.

What Are the Common Fabrics Used in Trench Coats?

Trench coats are typically made from:
Cotton blends (cotton + polyester): breathable and durable.
Taffeta: smooth, crisp, often used in lightweight trench coats.
Polyester blends: wrinkle-resistant, water-repellent, but often chemically treated.
Functional coated fabrics: designed for water and wind resistance, but may involve toxic finishes.
While these fabrics enhance durability and style, chemical finishing processes can introduce potential health hazards.

Harmful Substances in Fabric Production

1. PFAS (Per- and Polyfluoroalkyl Substances – the “Forever Chemicals”)
Purpose: Used to provide water, stain, and oil resistance.
Health Risks: PFAS are extremely persistent in the environment and may enter the body through skin or wastewater. Linked to endocrine disruption, immune damage, reproductive issues, and cancer.

2. Formaldehyde and VOCs (Volatile Organic Compounds)

Purpose: Commonly used for wrinkle resistance, shrink-proofing, and fabric finishing.
Health Risks: Can cause skin irritation, allergic reactions, respiratory problems, and long-term cancer risks.

⚠️ Additionally, some fabrics may contain azo dyes (which release carcinogenic amines) and heavy metals (such as chromium and lead), both of which are harmful to skin health.
