Why Should You Choose Low Formaldehyde Interlining?

Abstract

This article explains what low formaldehyde interlining is, why it matters for garment safety and quality, and how manufacturers and consumers benefit from using it.

What Is Low Formaldehyde Interlining?

Formaldehyde is commonly found in textile finishing and adhesive treatments used in fabrics and interlinings. While it improves durability and wrinkle resistance, excessive formaldehyde can be harmful to human health.

Low formaldehyde interlining uses modified resins or adhesives designed to reduce formaldehyde emission to safer levels, making garments more comfortable and eco-friendly without compromising performance.

Why Should Manufacturers Use Low Formaldehyde Interlining?

Brings several advantages both for textile producers and garment consumers.

1. Health and Safety Assurance
   Interlinings with low formaldehyde help prevent allergic reactions, skin irritation, and respiratory discomfort, especially for sensitive users and children.

2. Regulatory Compliance
   Many countries now impose strict limits on formaldehyde levels in textiles. Choosing low formaldehyde interlining ensures garments meet international standards such as OEKO-TEX® and REACH.

3. Improved Product Value
   Garments labeled “low formaldehyde” or “eco-friendly” appeal more to consumers concerned about safety and sustainability.

4. Enhanced Comfort and Freshness
   Fabrics fused with low formaldehyde interlining have a cleaner feel and no chemical odor, improving wearing comfort.

What Are the Drawbacks of Regular Formaldehyde Interlining?

Despite being widely used in older production methods, high-formaldehyde interlining has several disadvantages:

• Potential Health Risks: Prolonged exposure may cause allergies or irritation.

• Odor Issues: Garments may carry a noticeable chemical smell.

• Compliance Problems: Many export markets reject products exceeding formaldehyde limits.

• Environmental Impact: Formaldehyde contributes to volatile organic compound emissions.

How Does Low Formaldehyde Interlining Perform?

Modern low-formaldehyde interlinings are engineered to maintain the same strength, adhesion, and shape retention as traditional types. Manufacturers achieve this using advanced adhesive formulations that reduce or eliminate harmful chemicals while preserving functionality.

Tests show that low-formaldehyde versions can achieve similar peel strength, washing durability, and fusing stability when bonded under correct temperature and pressure conditions.

What Fabrics Benefit Most from Low Formaldehyde Interlining?

• Children’s Clothing: Skin-friendly and safe for prolonged contact.

• Shirts and Blouses: Offers comfort and crispness without odor.

• Uniforms and Workwear: Reduces exposure risk for daily wearers.

• Eco-Friendly Garments: Ideal for sustainable fashion brands focused on health and safety.

How Can Manufacturers Ensure Low Formaldehyde Quality?

1. Source Certified Materials
   Always buy interlining from suppliers that provide formaldehyde test reports or certifications.

2. Monitor Production Parameters
   Control bonding temperature and dwell time to prevent chemical decomposition.

3. Regular Quality Testing
   Conduct laboratory tests for formaldehyde release, wash fastness, and adhesive stability.

4. Maintain Storage Conditions
   Keep interlining in dry, ventilated areas away from moisture and direct heat to preserve chemical stability.
