1. History of Waterproof Fabric
Waterproof fabric is invented by Charles Macintosh, who is a Scottish chemist.
After centuries of development, waterproof fabric has made many great improvements. Gore Tex
waterproof fabric is a light waterproof fabric invented by American WLGore & Associates, Inc. It is thin,
strong and durable, has waterproof, breathable and windproof function. It breaks through the general
shortcomings of impermeability of waterproof fabric, known as the "Century of the cloth." GORE-TEX
waterproof fabric is not only widely used in aerospace, military and medical aspects, but also used by the
world's top brand, made of a wide range of casual clothing line.

2. Definition of Waterproof Fabric
Waterproof fabric is a new kind of textile fabric. It is compounded with polymer waterproof breathable
materials (PTFE membrane) plus fabrics.
Among all waterproof fabrics, breathable waterproof fabric is a high-class one. The main functions of
waterproof fabric are: waterproof, breathability, insulation, windproof and warm. Speaking from the
production process, technical requirements of breathable waterproof fabric are generally much higher
than other common fabric; also from the quality point of view, breathable waterproof fabric also has
some distinct functional characteristics. Breathable waterproof fabric at the same time of strengthening
the fabric airtight, watertight, while its unique vapor permeability properties allow moisture inside the

structure quickly discharged, to avoid breeding mold. And it can always keep the body dry, the perfect
solution for breathable and windproof, waterproof, thermal and other issues. Breathable waterproof
fabric is an environmentally friendly new fabric.
High-quality waterproof fabric is free from the water seepage problem even in humid climates for a long
time. For example, if you walk in wind and rain for a long time outdoors, kneeling or sitting on the wet
ground, waterproof fabric clothes won’t have water seepage.
3. Working Principle of Waterproof Fabric
In the state of water vapor, water particles are very small. According to the principle of capillary
movement, it can successfully penetrate into the other side of capillary, which causes vapor permeability
phenomenon. When water vapor condensed and becomes larger water droplets, due to the surface
tension of water droplets, water molecules cannot penetrate the water drops smoothly to the other side.

It prevents the water penetration, so that the vapor permeable membrane is equipped with waterproof
function.
Waterproof fabric is a kind of chemical textile fabric with polyester waterproof fabric as the domination.
Waterproof fabric manufacturer in China is concentrate in Jiangsu province such as Shengze Town,
Wujiang City. There is another place with massive waterproof fabric factory, which is Shaoxing. These
two places concentrate 99% of capacity of China waterproof fabric..
Waterproof fabric is a very common kind of furniture fabric which is widely used in umbrellas, raincoats
and other articles of daily use.
4. Waterproof Fabric Characteristics
Sliding: waterproof fabric and breathable polyester waterproof fabric with Teflon coating has a lower
coefficient of friction. The loaded sliding friction is only in the values of 0.05-0.15.
Heat resistance: waterproof fabric has excellent resistance to heat and low temperature. It can bear the
high temperature to 300 ℃, it generally can be used continuously between 240 ℃ ~ 260 ℃, with
significant thermal stability. Waterproof fabric can work without embrittlement in freezing temperature.

Not sticky: breathable waterproof fabric and polyester waterproof fabric is treated with Teflon coating
adhesion. Though a thin film, it also shows a good waterproof, anti-oil pollution function.
Moisture resistance: waterproof fabric won’t stick on any water and oil stain. If it is stuck with a small
amount of sticky dirt, just simply wipe is clean, which saves time and improves efficiency.
Wear resistance: waterproof fabric under high load has excellent wear resistance. It is durable.
Corrosion resistance: nylon and polyester waterproof fabric is almost free from drugs erosion, to protect
parts from any kind of chemical corrosion.
Through the above description it can be seen that compared to the conventional cloth fabric, waterproof
fabric has the properties of heat resistance, moisture resistance and wear resistance. More importantly,
it overcomes the usual problem of rain erosion of other fabric.

5. How to Wash Waterproof Fabric
All the E-PTFE films clothes are machine washable. There is no permanent waterproof performance loss
after washing.
The main considerations:
1, you need to pull up all of your jacket zip, fasten buttons, stickers, otherwise it will cause distortion of
the waterproof fabric.
2, Do not add fabric softener - softener may cause adhesive strip, fit film out of the lining, then the
clothes will be scrapped.
3, do not use hot water, warm water – waterproof fabric is afraid of high temperature.

There are two types of waterproof fabric from the aspect of process.
Born waterproof fabric uses PTFE film to achieve waterproof effect. While production, special materials
and special techniques are used so that the fabric produced have waterproof function, such as
micro-molecular technologies. While waterproof, it is also breathable. Water droplets sprinkle on top of
the fabric, the back is not wet. If you put the fabric on the kettle spout, you can see steaming out from
the other side of the breathable waterproof fabric.

Acquired waterproof fabric, the fabric itself is ordinary, has no waterproof effect. After special
post-processing, it has waterproof features, such as: coated with waterproof coating, spray some
waterproof reagents. This is the most common waterproof fabric in the market. It is mainly used for bags,
tents, assembling wardrobes. Its disadvantage is that as time goes on, waterproof effect will be
weakened.
Generally waterproof fabric relies on post-processing. It is common fabric with a layer of waterproof
coat. Born waterproof fabric has obvious advantages, but for reasons of raw materials, technology and
