Cooling single-sided knitted fabric: How to bring coolness and comfort in the hot summer?

Production process of cooling single-sided knitted fabric
Cooling single-sided knitted fabric, as the name suggests, is a new type of fabric obtained by finishing with special cooling fibers or functional additives on the basis of traditional single-sided knitted fabric. Single-sided knitted fabric itself is widely used in underwear and sportswear due to its good breathability, elasticity and softness. However, in order to meet the cool demand for summer wear, researchers began to explore how to give fabrics more cooling properties while maintaining these advantages.

1. Application of cooling fibers
Cooling fibers are a major breakthrough in textile technology in recent years. During the manufacturing process of these fibers, special minerals, ceramic powders or polymer materials are added to make the fibers themselves have higher thermal conductivity and heat absorption capacity. When the human body comes into contact with the fabric, the cooling fiber can quickly absorb the heat emitted by the human body, and conduct the heat to the surface of the fabric through the microstructure inside the fiber, and then dissipate it into the air, thereby achieving a cooling effect.

2. Functional additive finishing
In addition to directly using cool fibers, another common production method is to use functional additives to finish single-sided knitted fabrics. These additives usually include phase change materials, microcapsule technology, etc., which can form a special film on the surface of the fabric or inside the fiber. When the body temperature rises, this film will undergo a phase change from solid to liquid, absorbing a large amount of heat; and when the body temperature drops, it will change from liquid back to solid and release heat. This phase change process can continue, thus forming a dynamic heat exchange system between the fabric and the skin, keeping the wearer's body temperature within a relatively comfortable range.

Cooling mechanism of cooling single-sided knitted fabrics
The cooling properties of cooling single-sided knitted fabrics do not come out of thin air, but are based on a series of complex physical and chemical processes. These processes mainly include the absorption, conduction and release of heat, as well as the use of phase change materials.
1. Absorption and conduction of heat
The special ingredients in cool fibers and functional additives, such as minerals, ceramic powders or phase change materials, have good thermal conductivity. When the human body comes into contact with the fabric, these components can quickly absorb the heat from the surface of the human skin and conduct the heat to the surface of the fabric through the microstructure inside the fiber or film. Because the single-sided knitted fabric has good breathability, this heat can be quickly dissipated into the air, thereby reducing the wearer's perceived temperature.

2. Application of phase change materials
Phase change materials are the key to achieving a cool feeling in cooling single-sided knitted fabrics. These materials undergo phase changes within a specific temperature range, from solid to liquid or vice versa. During the phase change process, the material absorbs or releases a large amount of heat, thereby playing a role in regulating temperature. When worn in summer, phase change materials can absorb the heat emitted by the human body to keep the fabric cool; in winter, they can keep warm by releasing heat. This intelligent ability to regulate temperature makes cooling single-sided knitted fabrics suitable for all seasons, especially for summer wear.

Application of cooling single-sided knitted fabrics in clothing
The cooling characteristics and superior physical properties of cooling single-sided knitted fabrics have made them widely used in the field of clothing. The following are several main application scenarios:
1. Summer sportswear
During summer sports, the human body is prone to sweating and generates a lot of heat. Cooling single-sided knitted fabric has good air permeability and moisture absorption, which can quickly evaporate sweat. At the same time, its cool feeling can reduce the wearer's body temperature, reduce the feeling of stuffiness, and improve sports performance.

2. Underwear
Underwear is in direct contact with the skin, and has extremely high requirements for the feel, breathability and comfort of the fabric. Cooling single-sided knitted fabric has become the preferred fabric of many underwear brands with its soft, smooth feel and cool wearing experience. Especially in summer, wearing cooling single-sided knitted fabric underwear can effectively reduce the friction between the skin and the fabric and improve the comfort of wearing.

3. Home wear
In the hot summer, home wear also needs to have a cool feature. Home wear made of cooling single-sided knitted fabric, such as pajamas and home pants, is not only soft and comfortable, but also brings a cool feeling when worn, so that people can feel cool and comfortable at home.

4. Outdoor clothing
For people who like outdoor activities, the high temperature in summer is often a challenge. Outdoor clothing made of cooling single-jersey knitted fabrics, such as sun protection clothing and sun hats, can not only provide effective sun protection, but also reduce the wearer's body temperature through its cooling properties, making outdoor activities more relaxing and enjoyable.
