Black Grey Wool/Polyester Knit Plaid Fleece Fabric's thermal insulation performance 1. Wool's natural thermal insulation advantage

As an important component of fabrics, wool gives Black Grey Wool/Polyester Knit Plaid Fleece Fabric unique thermal insulation properties. Wool fibers have a unique microstructure, and the surface is covered with many tiny scales, which can lock air and form a natural thermal insulation layer, effectively slowing down the loss of heat. At the same time, wool fibers contain a large number of air sacs, which can absorb and store the heat emitted by the human body, further enhancing the fabric's thermal insulation effect.

Wool also has good moisture absorption and breathability, which can absorb moisture generated by the human body and expel it from the body to keep the body dry and comfortable. This feature is particularly important in winter, because a humid environment will accelerate the loss of heat, and wool fabrics can effectively avoid this.

2. Technological warmth of polyester fiber
In addition to the natural warmth advantage of wool, Black Grey Wool/Polyester Knit Plaid Fleece Fabric also adds polyester fiber to further enhance the warmth performance of the fabric. Polyester fiber is a synthetic fiber with high strength and elastic recovery ability, which can maintain the shape and stability of the fabric. At the same time, polyester fiber also has good windproof performance, which can effectively block the invasion of external cold air, thereby reducing heat loss.

In high-tech sportswear, polyester fiber is often used to achieve the dual effects of breathability and warmth. Through special textile processes and processing technologies, polyester fibers can form tiny breathable channels, which can effectively block the entry of external cold air while maintaining the breathability of the fabric. This technology is also used in Black Grey Wool/Polyester Knit Plaid Fleece Fabric, so that the fabric can maintain a certain degree of breathability while keeping warm, making the wearer more comfortable.

3. Knitted plaid design for enhanced warmth
In addition to the material advantages of wool and polyester, Black Grey Wool/Polyester Knit Plaid Fleece Fabric also uses a unique knitted plaid design. This design not only adds to the fashion sense of the fabric, but also enhances its warmth performance to a certain extent.

The knitted plaid structure can form more air layers, which can further slow down the loss of heat. At the same time, the plaid structure can also increase the surface area of ​​the fabric and increase the contact area between the fabric and the air, thereby enhancing the thermal insulation effect of the fabric. This design makes Black Grey Wool/Polyester Knit Plaid Fleece Fabric more outstanding in terms of warmth performance.

The thermal insulation performance of Black Grey Wool/Polyester Knit Plaid Fleece Fabric benefits from the natural warmth advantages of wool, the technological warmth blessing of polyester fiber, and the warmth enhancement of the knitted plaid design. The combined effect of these factors makes the fabric perform well in terms of warmth and can withstand the severe winter climate. At the same time, the fabric also has good air permeability, moisture absorption and wear resistance, so that the wearer can stay comfortable and dry while enjoying warmth. Therefore, Black Grey Wool/Polyester Knit Plaid Fleece Fabric is one of the ideal fabrics for making winter coats.
