Waterproof Polyester Fabric

-- Steady & Reliable Manufacturer --

Introduction

Our **Waterproof Polyester Fabric** is a technical textile designed to be completely impermeable to water, crucial for functional outerwear and gear. This is achieved by applying a Polyurethane (PU) coating or a specialized membrane lamination to the woven polyester base. The polyester fiber itself provides excellent durability and colorfastness, while the coating or membrane provides the high hydrostatic head rating required for true waterproofing. We offer 2-layer, 2.5-layer, and 3-layer laminated systems, tailored to breathability (MVTR) and durability requirements.

This fabric is essential for garments requiring protection from heavy rain, snow, and extreme weather.

Advantage

**Guaranteed Water Protection:** Achieves high hydrostatic head ratings, meaning the fabric can withstand significant water pressure without leakage.

**Excellent Durability:** Polyester is inherently strong and abrasion-resistant, ensuring the waterproof shell lasts longer in rugged conditions.

**Windproof Barrier:** The coating/membrane acts as a complete barrier to wind, providing excellent protection against wind chill.

**Versatile Weight Options:** Available in heavy-duty weights for tents or ultra-lightweight versions for packable emergency rain gear.

Application

Technical Rainwear and Shell Jackets: Used for waterproof, breathable jackets for hiking, cycling, and mountaineering.
Outdoor Gear and Bags: Essential for backpacks, equipment covers, and specialized storage bags.
Safety and Industrial Outerwear: High-visibility rain gear for construction and marine workers.
Tents and Tarps: Durable, lightweight fabric for temporary outdoor shelters and covers.

Payment & Shipping

Custom waterproof orders require a T/T 30% deposit upon final approval of the waterproof rating (hydrostatic head test report).

**Performance Certification:** We provide third-party lab reports confirming the fabric's waterproof rating (mm) and, if requested, the breathability (MVTR).
**Handling:** Fabric is carefully rolled, avoiding folds and creases that could damage the waterproof coating/membrane.

Frequently Asked Questions (FAQ)

Q: What is the difference between waterproof and water-resistant?
A: Water-resistant repels light rain, but waterproof (with a rating >1,500mm) is totally impermeable to water under pressure, often requiring taped seams on the garment.

Q: How do you make the fabric breathable while waterproof?
A: We use microporous membranes (like TPU or ePTFE) which have pores too small for liquid water to pass through but large enough for water vapor (sweat) to escape.

Q: Does a PU coating crack over time?
A: Low-quality or excessively thick PU coatings can crack. We use high-grade, flexible PU and TPU coatings designed for superior flex resistance and longevity.
