The most distinctive function of the thermal yarn is to reflect the far infrared rays emitted from the body and to keep the wearer stay warm against the extreme climates. By utilizing this specific feature, Sunny Special hereby offers our customers the far infrared fabrics which is produced with the inbuilt functionalities that achieve the insulation effect as well as to accommodate different demand for winter clothing.
The thermal material, which is blended into the fiber during its production, is permanently embedded within the yarn itself against the odd of weakening its functionality due to laundering. The primary function of the far infrared fabrics is to absorb and transform the heat energy transmitted from the sun into utilization by radiating it back onto the human body at a specific wavelength of 8 to 14 μm. Such functional fabrics are able to regulate the temperature based on the environment and body temperature to retain a constant temperature buffer as well as to avoid diminishing comfort for the wearer.
We substitute the originally less-effective fabric with the Sun Shield Warm fabrics in an attempt to offer our customers with lighter fabric weight and greater thermal balance.
The most remarkable function of negative thermal expansion is to suppress the effect of temperature variation by retaining the body temperature and insulating the air conductivity. The fleece fabric is commonly known as the most iconic fabric for negative thermal expansion, and its identical properties such as its fluffiness and softness are incorporated in the fibers, which facilitates a stronger barrier for thermal balance than the original three-layer structure fabrics. This revolutionary design has structurally arranged the fibers in a controlled manner to avoid any redundant fiber shedding and to ensure the minimal environmental impact.
The effect of thermal insulation is primarily dominated by the thermal fabric structure, which are systematically deposited within the yarn arrangement, assuring the stability of heat maintenance for the wearer against any hostile environment. There is no energy waste issue ever occurred during the production despite of the strictly standardized manufacturing process.
Replacing a percentage of the yarn with thermal yarn greatly improves the warmth and wind resistance thanks to the calendaring process. Because of the inherent color of the thermal yarn, the fabric can be two tone under normal dyeing conditions for an effect that is both functional and attractive.
Thermal yarn is cleverly used on the double-layer structure close to the skin. The yarn can exert the maximum efficiency of far-infrared thermal feature, and the mélange fabric on the front can also have good elasticity and windproof effects.
The mechanically elastic woven fleece has wind-resistant and water-repellent functions like woven fabric on the outside. On the inside, it has long bristles like knitted fleece, which is soft and comfortable.
In addition to its distinctive appearance, the organization of the fabric is specially designed with three layers. It also boasts warmth retention by trapping air.
