In the cold winter, sweatshirts are one of the clothes that people usually choose. But when choosing a sweatshirt, people tend to pay attention to its thermal performance. Many people will find that the gram weight of the sweatshirt is different, so what is the effect of different gram weights on the thermal performance?
First of all, we need to know what the grammage of the sweatshirt is. Gram weight refers to the gram weight per square meter of sweatshirt fabric, which is generally based on grams. The higher the grammage, the heavier the fabric and the better the thermal performance. But that doesn't mean that the higher the grammage, the better the warmth. Because the warmth performance is also related to the material of the fabric and the weaving method.
For sweatshirt materials, the common ones are cotton, polyester cotton, polyester, etc. Cotton sweatshirts are soft and delicate, with good breathability, but relatively poor thermal performance. Polyester-cotton sweatshirts have some thermal insulation properties, but they may not be as breathable as cotton. Polyester fabrics have strong thermal insulation performance and relatively weak air permeability. Therefore, the choice of fabric will also affect the thermal performance.
In addition to the fabric, the knitting method of the sweatshirt is also one of the factors that affect the thermal performance. Common weaving methods are knitting and weaving. Knitted sweatshirts are knitted from knitted knits, which are soft, elastic and breathable. Woven sweatshirts are woven by shuttle looms, which are relatively heavy and have good thermal performance. Therefore, the choice of weaving method will also affect the thermal performance.
Now, let's take a concrete look at the effect of different grammages on thermal performance. First of all, low-weight sweatshirts are generally thinner and suitable for wearing indoors or when the weather is warm. This kind of sweatshirt is generally breathable and comfortable, but the warmth is relatively weak. Therefore, this sweatshirt may not be suitable for cold winters.
Medium-weight sweatshirts can improve thermal insulation to a certain extent. This sweatshirt is relatively thick, which can effectively block the cold wind and maintain body temperature. At the same time, breathability and comfort are also better. This sweatshirt is a good choice for some weather that is not too cold.
And a high-weight sweatshirt is a warm choice. This sweatshirt is usually thick and can effectively protect against the cold. At the same time, due to the thicker fabric, the air permeability may be poor, so you need to pay attention when choosing. Primed for colder weather, it provides you with warm protection.
Generally speaking, different grammages do have a certain impact on the warmth performance. The low gram sweatshirt is suitable for warm weather, the medium gram sweatshirt is suitable for cold weather, and the high gram sweatshirt is suitable for cold climate. Of course, in addition to the grammage, the material of the fabric and the weaving method should also be considered. The important thing is to choose a sweatshirt that suits your needs.
When buying a sweatshirt, you can choose the right grammage according to your needs. If you're often in cold weather, you can opt for a high-gram sweatshirt. If you're often active indoors in warm temperatures, you can opt for a low-weight sweatshirt. Considering your own needs and seasonal characteristics, choosing the right sweatshirt can keep you warm and comfortable in winter.
