Breathability of knitted elastic fabrics: a double guarantee of comfort and health

1. The basic principle of breathability of knitted elastic fabrics for casual clothing
The reason why knitted elastic fabrics have good breathability is due to their finely designed fiber structure and weaving process. In short, breathability refers to the ability of fabrics to allow air and water vapor to pass through. This feature is essential for regulating the human microclimate and keeping the skin dry. In knitted elastic fabrics, the fineness of the fiber, the weaving density, and the porosity formed by it are the key factors that determine breathability.

Fiber fineness: The finer the fiber, the more fibers per unit area, and the more gaps between the fibers, thereby increasing the channels inside the fabric, which is conducive to the circulation of air and water vapor.
Weaving density: Compared with tightly woven fabrics, knitted elastic fabrics often use a looser weaving structure, which reduces the overlap between fibers, increases the open area on the surface of the fabric, and further improves breathability.
Porosity: Porosity refers to the proportion of the void volume inside the fabric to the total volume. High porosity means that more air and water vapor can pass through the fabric, which is particularly important for keeping the body comfortable.
2. The Importance of Breathability for Daily Wear

Body Temperature Regulation: In the hot summer or when performing high-intensity activities, the human body will generate a lot of heat and sweat. Knitted elastic fabrics, with their excellent breathability, can quickly discharge excess heat and moisture from the body, effectively preventing the feeling of stuffiness and keeping the body cool.

Reduce sweat accumulation: Good breathability means that sweat can evaporate faster, reducing the accumulation of sweat on the skin surface, avoiding the discomfort caused by long-term moisture, and also reducing the body odor caused by poor sweat evaporation.

Promote personal hygiene: Sweat is a breeding ground for bacteria. The breathability of knitted elastic fabrics helps sweat to be discharged in time, reducing the environment for bacterial growth, thereby reducing the risk of skin infection and maintaining personal hygiene.

Improve sports performance: For athletes, fabrics with good breathability can reduce resistance during exercise, improve exercise efficiency, keep the body dry, and enhance the overall sports experience.

3. How to choose the right knitted elastic fabric

Faced with a wide range of knitted elastic fabrics on the market, how should consumers choose to ensure that they have good breathability? The following suggestions may help:

Check product information: Pay attention to the fiber composition and weaving method on the fabric label, and give priority to products with fine fibers and appropriate weaving density.
Touch experience: Feel the softness and breathability of the fabric by touch. Generally speaking, fabrics that feel light and soft have better breathability.
Breathability test: Some merchants will provide fabric breathability test reports, and consumers can refer to these data to make more scientific judgments.
Brand reputation: Choose well-known brands, which often have stricter quality control systems and more guaranteed product breathability.
