Waterproof Fabric
Specially designed for shoes and bags, wear-resistant and durable, with good shaping, meeting the material requirements for footwear and bags.
Waterproof Fabric
Waterproof fabric is a type of functional textile material that has been treated through special processes to effectively prevent liquid water penetration, and depending on the technical approach, it can also have multifunctional properties such as breathability, windproofing, and abrasion resistance.
It changes the surface or internal structure of the fabric through coating, lamination, high-density weaving, or nano-processing, making water molecules unable to penetrate, while some high-end products can also allow water vapor to pass through, achieving a dual regulation function of 'waterproof and breathable'.
This type of fabric is widely used in outdoor clothing, military equipment, medical protection, architectural membranes, footwear, and luggage, becoming an important branch of functional fabrics in the modern textile industry. From traditional waxed cotton and rubber raincoats to today's high-tech membrane fabrics like Gore‑Tex and eVent, waterproof fabric technology has gone through a revolutionary development, evolving from single-function waterproofing to multifunctional integration, and from fluorine-based treatments to environmentally friendly, fluorine-free options.
Waterproof Fabric Characteristics
l Core waterproof performance: It has excellent water barrier capability and water repellency, capable of blocking rain and snow from penetrating. Water droplets roll off the surface in beads without soaking. High-quality products will seal the seams to prevent leakage, meeting waterproof needs in different scenarios.
l Breathability and Moisture Permeability: High-end waterproof fabrics can achieve a balance between waterproofing and breathability/moisture permeability. They can block liquid water while allowing body sweat to evaporate and release, preventing stuffiness during wear and enhancing comfort. The breathability and moisture permeability effects of fabrics with different processes vary slightly.
l Physical and mechanical properties: Possesses good wear resistance and tear strength, capable of withstanding daily friction and scratches, extending service life; at the same time, it balances flexibility and wrinkle resistance, ensuring wearing comfort and a neat appearance, and is convenient for processing and manufacturing.
l Environmental adaptability: Capable of adapting to different temperature ranges, with good weather resistance, able to withstand sun, rain, and ultraviolet erosion, not prone to aging or mildew, and can maintain stable performance even in complex environments such as humidity.
lSpecial functional features: Most products combine windproof and warmth-retaining effects, while some high-end fabrics can achieve additional functions such as oil resistance and flame retardancy. At the same time, fluorine-free eco-friendly processes have become the mainstream in development, balancing performance and sustainability.
Main categories and applications of waterproof fabrics:
Waterproof fabric type | Main product categories | Material composition | Main application scenarios | Performance characteristics |
| Raincoats, umbrellas, lightweight tents, economical outdoor coverings | Polyurethane (PU) coating + textile base fabric (nylon, polyester, etc.) | Everyday rain gear, lightweight outdoor gear, economical waterproof coverings | lightStrong, flexible and cost-effective; prone to aging and degradation after UV rays or washing |
| Industrial canvas, waterproof bags, truck coverings, marine applications, protective clothing | Polyvinyl chloride (PVC) coating + textile base cloth (polyester, cotton, etc.) | Industrial protection, heavy-duty waterproofing, truck covering, marine equipment | DefendExcellent water performance, strong durability, easy to clean; poor air permeability and heavy weight |
| Outdoor jackets, hiking shoes, gloves, high-performance tents, mountaineering clothing | Polytetrafluoroethylene (PTFE) microporous membrane + textile base cloth (usually nylon or polyester) | High-intensity outdoor activities such as high-altitude climbing, hiking, skiing, mountaineering, etc. | Waterproof, windproof and breathable; higher cost, but durable |
| Medical protective clothing, inflatable products, outdoor backpacks, sportswear, waterproof bags | Thermoplastic polyurethane (TPU) film + textile base fabric (nylon, polyester, etc.) | Medical protection, water sports, outdoor equipment, sportswear | High strength, good elasticity, non-toxic and environmentally friendly; oil-resistant and wear-resistant, suitable for high temperature environments (-35~75℃) |
Oil wax cotton | Traditional raincoats, outdoor jackets, retro backpacks, hats | Wax-impregnated cotton | dayOften lightly rainproof, retro clothing, traditional rain gear | Durable, classic aesthetic; heavy, requires regular re-waxing, poor breathability |
Nylon ripstop fabric (Ripstop) | Outdoor backpacks, waterproof bags, jackets, cycling raincoats | High-density nylon fabric + PU/silicone coating | Outdoor activities, cycling equipment, diving equipment, tear resistance demand scenarios | HeavyLight weight, strong tear resistance, easy to store; breathability is limited when the coating is thick |
| Waterproof bags, tool bags, industrial protective equipment | PVC layer + mesh base fabric (polyester, cotton, etc.) | Non-contact waterproof bags, tool protection, industrial fields | Waterproof, tear-resistant; suitable for -15~45℃, brittle at low temperatures and melt at high temperatures, prone to odor |
| High-end waterproof backpacks, river tracing bags, airtight waist bags, food contact bags | TPU film is bonded to fabric; single or double-sided bonding | Outdoor adventures, river tracing activities, food preservation, and areas requiring environmental certification | Cold and heat resistant (-35~75℃), strong welding fastness, no odor and non-sticky; environmentally friendly degradation (3-5 years) |
| Sports waterproof clothing, ski clothing, outdoor clothing | ePTFE (expanded polytetrafluoroethylene) coating + textile base fabric | High-intensity aerobic outdoor sports, skiing, mountaineering and other professional sports | High breathability (higher than Gore-Tex), good moisture conductivity; relatively weak durability |
| Police raincoat, climber raincoat, professional outdoor clothing | Waterproof and breathable coating + textile base fabric (usually high-density fabric) | Extreme weather outdoor operations, mountain climbing, police activities | Good waterproof and breathable effect; higher price and high maintenance requirements |
| Waterproof mattress protectors, shower curtains, outdoor furniture covers | Polyester fiber + waterproof coating (such as PU) | Home waterproofing, mattress protection, outdoor furniture protection | Light weight, good breathability, durable; washable, suitable for daily home use |
