The cold winter is really coming, and the temperature difference between morning and evening has gradually widened. In addition to coats such as cotton coats, down jackets, and woolen coats, warm inner layers must also be arranged.

When it comes to warm inner wear, we have to talk about sweatshirts and sweaters.

Sweatshirts and sweaters are must-have fashionable items in autumn and winter. Most styles are designed to be worn inside or outside. It can be worn outside and both have a good thermal insulation effect. However, in terms of warmth retention, there are always different opinions on who is better, sweatshirts or sweaters.

01 / The material and thermal insulation principle of sweatshirt

Sweatshirts can be divided into pure cotton sweatshirts, fleece sweatshirts, fleece sweatshirts and other categories.

Pure cotton sweatshirts are generally made of cotton. When fluffy, they contain a lot of air, which reduces the heat transfer efficiency and maximizes the efficiency of heat transfer. Keep the floor warm. Pure cotton sweatshirts are very popular because they are comfortable, soft, breathable, warm, hygroscopic, heat-resistant, and alkali-resistant. For many thin sweatshirts in spring and autumn, everyone prefers to buy pure cotton ones.

The material of fleece sweatshirts is mainly polyester fiber. Our common fleece, polar fleece, coral fleece, etc. All kinds of fabrics can be collectively called fleece sweatshirts. The hollow chemical fibers in the fleece sweatshirt fabric contain enough air in a certain insulation layer to maximize warmth. Because it is warm, breathable, lightweight, quick-drying, wear-resistant, stretchable, easy to compress, and easy to care for, it is favored by fashionable men and women in winter.

Fleece sweatshirts are a bit more complicated. They are generally divided into three types. One is that the sweatshirt itself is made of fleece fabric; The back has a fleece treatment, which can basically be understood as a fleece sweatshirt. One is a sweatshirt made of pure cotton or other fabrics + polar fleece lining. The two layers of fabric are not very thick, but together they will be very warm. It may need a little care when putting it on and taking off. There is also a sweatshirt cloth composite short plush fabric, which is also very popular in the market. Simply put, a fleece sweatshirt is a complex that superimposes the warmth and properties of N materials.

If you rank them in terms of warmth retention, they are roughly fleece sweatshirts > fleece sweatshirts > pure cotton sweatshirts, but there are also You should consider the thickness of the fabric. Thickened cotton sweatshirts are as warm as thin fleece sweatshirts.

02 / The material and thermal insulation principle of sweater

Us Often called sweaters, they are generally made of wool blends, and many people also call sweaters made of polyester fiber or other materials.

Wool has good warmth retention but is easy to pill, shrink, not wear-resistant, and difficult to take care of. It needs to be used during the production process. Add cotton, polyester and other fiber materials for blending to make the fabric more durable and easier to care for. Wool-blend sweaters contain a large amount of air in the middle of the curly wool, which largely prevents cold air from entering and escaping from the outside, thus playing a very good role in keeping warm. Woolen sweaters have plump feel, good warmth retention, good elasticity and comfortable wearing. They are one of the must-have styles for fashionable men and women in autumn and winter.

Knitted sweaters made of polyester fiber or other materials are less warm than sweaters made of wool blends, but they are wear-resistant. , not easy to pill, not easy to deform, easy to care for, and also very popular.

There is also a fleece sweater that adds a layer of polar fleece to materials such as wool blends or polyester fibers. The lining improves the warmth of the sweater through double layer superposition, but it is relatively thicker and not as light and soft as a pure sweater.

03 / Which one is warmer, a sweater or a sweater? How to choose?

When worn alone with a sweater or sweater, outdoors, the density of the sweater is relatively high and the wind resistance is relatively strong. The pores of the sweater are relatively large and can be penetrated by the wind, so the warmth of the sweater is stronger than that of the sweater. Indoors, there is not much difference in warmth between a sweater and a sweater, but the comfort of a sweater will be higher than that of a sweater, and it will also be more comfortable than a sweater.�Look thinner.

If a sweater or sweater is worn as an inner layer with a jacket, sweatshirts are looser because of the overall design, and sweaters can be compared. The close-fitting style, because there is a jacket on the outside to block the wind, the difference in warmth between a sweater and a sweater is not particularly big. Choosing a sweatshirt or a sweater can be determined based on personal preference and dressing style.

So, if you like to wear sweatshirts or sweaters outside, then sweatshirts will be better in terms of warmth and fashion. It’s suitable. Another thing is that sweaters are easy to snag when worn alone, but sweatshirts basically don’t have this concern. If you like to wear it with a jacket, if it is a casual jacket, it is good to choose a sweatshirt or a loose sweater. If it is a business casual or more ladylike jacket, choosing a slimmer sweater will fit better. Not everyone can wear it with a loose and casual sweater to create that unique charm. If paired with outerwear such as windbreakers and denim jackets, sweatshirts and sweaters are good choices.
