The Difference Between Sweat Absorption And Sweating Of Clothing Fabrics

In recent years, people have

The comfort and functional requirements are higher and higher, and with the increase of people's outdoor activity time, leisure clothes and

The trend of mutual penetration and integration is also increasingly favored by consumers.

The fabric of this kind of clothing requires not only good comfort, but also a sweat when it is full of activities. Clothes will not stick to the skin and produce a cold, wet and heavy feeling.

Therefore, the new requirements of moisture absorption and sweating function were put forward.

However, for

The moisture absorption and sweat perspiration of consumers will be confused.

In fact, this is the two concept.

Hygroscopic and dehumidifying.

First of all, let's talk about moisture absorption.

Synthesis

Take polyester as an example, in fact, its water absorption is small and its moisture permeability is poor.

Taking cotton as an example, its moisture absorption performance is good and its clothing is comfortable. But when the sweat volume of people is slightly larger, the cotton fiber will expand due to moisture absorption and paste on the skin. At the same time, the moisture dispersion speed is slower, causing a cold and wet feeling to the human body.

So, for all fabrics, especially

Products treated with hydrophilic auxiliaries in the finishing stage are good ways to improve moisture absorption.

But is it over? Does it solve the problem of keeping the wearer dry? Moisture absorption = perspiration?

Of course not!

As far as possible, the adsorbed moisture is discharged to the surface of the fabric. Under the condition of sunlight and good ventilation, the water evaporates fully, so as to keep the wearer's dry and comfortable.

and

Dehumidification depends mainly on

The physical structure form.

The vaporized moisture evaporated from the surface of the skin is first absorbed by the fabric (i.e. moisture absorption, that is, the moisture absorption of the fabric, rather than the fiber!). Then the capillary effect of the pores in the fiber (pores, pores, grooves) and the gap between the fibers causes moisture.

Adsorption and diffusion were carried out.

In this way, moisture moves to the surface of the fabric and evaporates, thus completing the process of dehumidification.

Therefore, only moisture absorption is not enough.

For some ordinary synthetic fabrics, we only use hydrophilic auxiliaries for finishing, and then flaunt moisture absorption "sweating", which has led us all to misunderstandings.

stay

In the production process, changing the shape of the spinneret hole and creating many grooves in the longitudinal direction of the fiber can improve the specific surface area of the fiber.

This improves the moisture conductivity of the fibers and achieves the effect of sweating through the wicking effect of these grooves.

For example, the use of COOLMAX for moisture absorption and perspiration

Certified polyester.

Its cross section is unique flat cross shape, and the fiber surface is longitudinally divided into four trenches.

The specific surface area is 20% larger than that of the conventional circle, so the sweat perspiration is higher than the conventional one.
