Principle Of Fast Drying Of Garment Fabrics

No matter what material is made of fast drying trousers, its comfort level is certainly worse than that of pure cotton fabrics. However, due to its special structure, it can dry quickly (wet clothes) after being soaked by sweat or wet by rain, so that the body surface is maintained or rapidly restored to a dry state.

At present, there are two main types of fast dry clothes sold on the market: 1., prevent splashing water and breathe freely; 2. do not waterproof, but dry quickly after wet.

The fabric used for ordinary clothing is nothing more than cotton, hemp and chemical fiber.

In fact, the fabric used for fast drying underwear is also chemical fiber.

But because of the different processing technology, fast drying underwear has different performance from ordinary clothes.

Quick drying principle

For waterproof and breathable fast dry trousers, from a technical point of view, the main principles are as follows:

1. make use of the difference between the minimum diameter of water droplet and the diameter of water molecules or air molecules.

We all know a common sense that even small droplets are much larger than the diameter of water molecules or air molecules.

Then, if the pore diameter of the fabric is controlled between the minimum diameter of the water droplet and the maximum diameter of the water molecules or the air molecules, the water droplets can not be entered, and the water molecules and the air molecules can be unimpeded.

The fabric made by this method is usually referred to as ultra-high density fabric or extra high density fabric.

This kind of fabric appeared long ago, and the readers over twenty years old will be impressed.

More than ten years ago, there was a very ordinary cloth in the shopping mall, with a bag of water on it, but the water could not penetrate into the cloth. It was a high density fabric.

This fabric has the advantages of light weight, durability, good moisture permeability and softness. The disadvantage is that after a period of time, the waterproofing performance will be greatly reduced, and because its spinning must be specially treated and the manufacturing cost is high, it has faded out of the market.

2. use microporous membrane.

The pore size of the film is between the smallest diameter of the droplet and the largest diameter of the water molecule or air molecule, and then the membrane is combined with the outer fabric to give the fabric waterproof and breathable function.

We need to focus on the fabric made in this way.

The key to the cloth made by this method is the film with micropores. There may be many ways to produce the microporous membrane, which can produce micropores through biaxial stretching of the film, or fill the filler with polymer to form pores between the polymer and the filler, and also make the pore free pores produced by laser technology.

Almost one hundred percent of the backpackers have heard of the name of the Ge re ex fabric, but it has been seen that the film can be said to be very few.

Usually, the clothes we see in the outdoor shop are the clothes made of Ge e ex fabric, which is formed after the combination of the Ge re x film and the outer fabric.

In fact, the Ge re x film has only a very thin layer.

With a certain degree of elasticity, whether it is color or texture, it looks a bit like pparent rubber for medical surgical gloves, but lighter and thinner, waterproof and breathable, and windproof.

Surely, readers will ask, since you say GORE TEX is so good, why not use GORE TEX to make fast dry trousers?

By comparing the GORE TEX fabric with the quick drying fabric, we will find that the two have waterproof and breathable properties.

For most fast drying fabrics, they do not have windproof properties. From the above table, we can see the similarities and differences between the common fast drying fabrics and gross re X.

In this way, the difference between fast drying underwear and GORE TEX fabric is obvious. Fast drying underwear emphasizes breathability and quick drying performance, and is lighter in weight and easy to clean.

It's a good choice for outdoor sports in the three quarter.

While winter is obviously unable to meet the needs, the garments made by the Ge re fabric are waterproof, breathable and ventilated.

However, when the body sweating much, the body's sweat is greater than the maximum amount of breathable clothing can be discharged, then it will not be very comfortable to wear.

But in the long term activities and in the more difficult activities, the clothes made of the use of gross re fabric can provide more complete protection for themselves.

3. the waterproof and breathable effect can be achieved by the interaction between the hydrophilic factors of different components in the inner and outer layers of the fabric and the interaction between water and water.

Water molecules adsorb water molecules on the high humidity side due to hydrogen bonds and other intermolecular forces. They are pported to the low humidity side by desorption on the polymer chain to achieve the purpose of air permeability.

4. utilize the characteristics of shape memory polymers.

The shape memory polymer has a qualitative mutation due to the smooth movement of the molecular chain.

And its permeability is adjusted with the change of temperature and humidity.

Using this shape memory polyurethane to produce waterproof and breathable fabrics, it can be used in the form of no hole laminating or coating. It reduces the shortcoming of the existence of micropores due to the micropores and the obstruction of the micropores, and more importantly, the moisture permeability of fabrics can change with the change of body temperature.

Achieve "intelligent" effect.

Make it suitable for wearing under various conditions.

For fast drying trousers that are not waterproof, but dry after drying, their technical accountants are not so mysterious. In the final analysis, they are just some chemical fiber fabrics.

But the same chemical fiber fabric, its composition fiber is also different, some are viscose acetate, some are blended, but the general characteristics are basically the same: not waterproof, but also no water absorption, good ventilation performance.

Once the body is not sweating or there are no external factors to wet the clothes, it will dry quickly under the action of body temperature or wind force, but the comfort of the clothes can be different because of the fabric.
