The influence of sweater weaving technology on the warmth retention of sweaters

The weaving process of a sweater has a significant impact on its warmth retention. Specifically, the following factors are closely related to the warmth retention of sweaters:

Material: The material of a sweater is the key factor determining its warmth retention. For example, wool is the most common sweater material, which has good insulation performance because wool fibers contain a large number of pores, which can absorb and maintain air, forming a thermal insulation layer. At the same time, the irregular and fluffy fiber structure on the surface of wool fibers can effectively block the invasion of cold air from the outside and maintain a stable temperature around the human body.

Weaving structure: The weaving structure of a sweater is also an important factor in keeping warm. Sweaters usually use special weaving or knitting techniques to create gaps and airbags between fibers through interlacing or dense weaving. These gaps and airbags can effectively isolate the cold air from the outside, while also maintaining a certain amount of air inside the sweater, forming a thermal insulation effect. Some sweaters also use special heavy weaving or double-sided weaving to increase their insulation performance.

Fabric texture thickness: The thicker the fabric, the denser the fuzz, and the better the insulation effect of the sweater.

Weaving density: Weaving density represents the number of needles per inch. The higher the density, the tighter the texture, so sweaters with higher density can better keep warm. A higher weaving density will make the fabric tighter, reducing temperature transfer and enhancing warmth retention.
