Now there are many new terms coming out every year.

"Originally went to the mall to buy thermal underwear, although the price is higher, but the good choice, all are three layers of warm, the fabric is pure cotton, now is different, not only the brand is much, the fabric name is also many."

When interviewed by a supermarket in the provincial capital, Ms. Xue, who was shopping for warm underwear, told her confusion about reporters.

It is understood that at the end of the 90s, when the thermal underwear was first appeared in the market, the initial selling point was the thermal insulation rate. The few brands launched were three layers of thermal underwear, and the inner layer and outer layer were made of pure cotton material, only the middle layer was chemical fiber. At that time, the product broke through the traditional thermal clothing loose, bloated, inactivity and lack of aesthetic feeling, and was very popular.

In the past more than 10 years, the brand, price and selling way of thermal underwear have changed a lot. But the insiders in the interview say that the core of the market of thermal underwear manufacturers is always around the product material, and the fabric is also changing.

Ms. Wang, who sells underwear for more than 10 years in a shopping mall in the central city of Hunan Province, told reporters that in his impression, colored cotton began to appear on the market around 2003, and many brands rely on this position.

Subsequently, the concept of the fabric and composition of the thermal underwear is constantly being refurbished. In the market, carbon card, magic card, heat card, Sevilla card and so on, and coral corduroy, pearl velvet, lamb hair and so on, have appeared in recent years. In recent years, bamboo charcoal fibers, modal and heating fibers have emerged.

Reporters recently visited the provincial capital market to see that the thermal underwear materials on the market are in addition to the most traditional pure cotton, as well as bamboo charcoal fibers, modal and polyester fibers. Almost every brand produces thermal underwear which has a variety of fabrics. "This industry has developed to the present, and it is more difficult to differentiate competition. For example, our company has developed a new fabric, sometimes it takes a year at most, and every second years, every brand will start to learn from it. All streets and lanes are similar fabrics. Even so, we must continue to study new fabrics, otherwise we won't be able to survive in many brands."

How to choose warm underwear?

Different populations demand different

The price of thermal underwear is very different, and the fabric types are various. This makes many consumers dazzled when they choose to buy, and don't know which kind of thermal underwear to buy is more suitable for themselves.

Wei Shouwen, chief and senior engineer of quality inspection department of Shandong Fiber Inspection Bureau, told reporters that the thermal insulation properties of the fabrics used in thermal underwear are relatively good, and the thermal insulation properties of traditional materials such as cashmere, wool and pure cotton are relatively well recognized. The elderly and children should pay more attention to warmth and comfort in choosing, and choose suitable thermal underwear such as cotton, wool floc and camel's floc. "For example, three layers of warm cotton underwear, the outer layer is pure cotton, only the middle layer is made of chemical fiber, which has good thermal insulation effect and comfortable body wear, but the air permeability is poor, and it is not fit for the elderly."

In addition, Wei Shouwen also reminded consumers to buy warm underwear, there are several steps, first of all, we need to see the product label, whether the material, warmth and so on are in line with their needs; secondly, we need to see whether the fabric of the whole product is defective or whether there is dyeing unevenness; third, when buying warm underwear, try not to buy too tight products, which will affect the blood circulation. "When choosing the thermal underwear, the price is only as a reference. It should be best for fabrics with good thermal performance, soft comfort, light weight and good elasticity. Moreover, we should try to buy regular underwear products in supermarkets, shopping malls and other formal channels, while the quality of products is guaranteed, and there will be problems in future.

Three layers of warmth, raising...

The production process has become more complicated.

In the interview, some experts told reporters that behind the change of the fabric and material of thermal underwear is actually the change of production process. Since 2001, the market began to pursue the effect of slimming and shaping. Almost all the thermal underwear did not use floc insulation layer, instead of using the fibers with better thermal performance or increasing the weight of the fabric, or using the technology of raising and raising hair to improve the thermal insulation effect of the products.

When visiting the market, the reporters also found that in the wholesale market of various shopping malls, the most common production processes were mainly raising and down, and some of them used down, and the three layers were actually much less warm.

A thermal underwear dealer told reporters that at present, the knitted thermal underwear sold in the Ji'nan market can be roughly divided into three types, one is wool Satin thermal underwear, the other is a double-sided fabric knitted by two-sided knitting machine, and the main raw materials are cotton, modal, wool, spandex and other fibers.

"There are also more common fleece underwear. It is a lint and knitted fabric woven by a single knitting machine. The fabric is usually dressed on the up side. The main raw materials are acrylic, cotton, viscose and spandex, which are good for warmth and breathability. The products are bright and colourful, and they are soft and elastic."

Another is the most traditional three layers of thermal underwear, woven by double sided circular knitting machine. The fabric is made up of 3 layers of inner, surface and sandwich. The common raw materials are cotton, polyester cotton, viscose and cellulose fiber, and the interlayer is 100% polyester elastic yarn. The price is more than that of the people.
