In winter, for me, a northeastern girl who loves to wear cheongsam, it is really useless.

It’s freezing outside and you need a down jacket when traveling. This is easy to solve, but the troublesome thing is leggings and shirts.

It’s okay to say that leggings are available in various thicknesses, but leggings are a bit troublesome.

In the past few years, I have purchased a few bottoming shirts every winter. However, cashmere bottoming shirts are warm, but they have poor wrapping properties, making the cheongsam not as snug as when worn next to the body.

Woolen base layer shirts are very tight, but they are never warm enough.

I heard that everyone wears German velvet bottoming shirts, so I bought one for a few dozen yuan to try on, but it was not as magical as the legend said and felt very cheap.

As a beauty lover who upholds the principle of "live and learn", I began to study bottoming shirts seriously.

DeRong base shirt

What is DeRong? Zhihu said, "DeRong is not a kind of fabric. It is a brand of acrylic yarn affiliated to the German company Bayer, which means it is a registered trademark.

Acrylic is actually a kind of chemical fiber , like our common polyester and nylon, are products of petroleum refining.

Due to its molecular structure, acrylic has good thermal insulation properties and is also called fake wool.

Adding acrylic fiber to the fabric has better warmth retention. Of course, the warmth retention of the fabric is also affected by the weaving process and finishing.

The biggest feature of acrylic fiber is that it is a kind of chemical fiber. It is warm and light, but its disadvantages are that it is easy to get dirty and its resilience is average.

Normally, the proportion of acrylic in so-called German velvet fabrics is more than 20%. It is difficult to distinguish between genuine and fake fabrics in the current German velvet market. DeRong does purchase yarn from the German company Bayer, but the ratio is not enough. After years of development, the normal ratio of DeRong fabrics is generally: 50-60% cotton, 20-30% acrylic, and 5-6% spandex. . Some German velvet fabrics also add some cashmere fiber, mulberry silk, etc.

The real German velvet fabric has two points. One is that it uses fiber from the German Bayer company and is equipped with genuine hangtags. It contains more than 20% acrylic fiber.

The base layer made of German velvet fabric is light, warm and has good elasticity, but it is chemical fiber after all and has a greater impact on the skin. German velvet fabric bottoming shirts cost less than 50 yuan, but the quality is worrying.

Cashmere bottoming shirts

The most comfortable winter underwear is cashmere products, which cost between 400 and 500 yuan. The price ranges from one thousand yuan.

The reason for such a big difference is not only related to the quality of the cashmere yarn itself, but also to the production technology.

As we all know, cashmere is grown in goats. Under the outer layer of the skin, there is a layer of fine velvet covering the roots of the goat's coarse hair. In winter, when the weather is cold, the goat's body grows cashmere to resist the wind and cold. When the weather turns warm in spring, the cashmere falls off and naturally adapts to the climate. Rare special animal fiber.

Cashmere is very precious not only because of its scarcity, accounting for only 0.2% of the world's total animal fiber production, but more importantly because of its excellent quality and characteristics. The price is considered to be the queen of fiber and is unmatched by all textile raw materials currently available to humans, so it is also called soft gold.

Basing shirts made of cashmere are usually 300 grams. Above. However, although cashmere products are light, soft and warm, they have poor resilience and are not very suitable as a base layer worn under a cheongsam.

Wool base layer

< p>Wool is produced from sheep and is also an animal protein fiber. It is soft and elastic and can be used to make textiles such as woolen wool, wool, blankets, and felt.

Wool products have a plump feel, good warmth retention, and are comfortable to wear. and other characteristics. The main factors for evaluating wool quality are fineness, curl, color, strength and grass content.

Wool production is large, and wool quality is divided into multiple stages due to differences in origin and processing technology. But basically the finer the wool fibers, the better the quality.

The quality of wool base sweaters is determined by the fineness of the wool itself and the weaving technology. That is to say, only qualified yarns with "high count" and "high quality" can weave exquisite, dense, fully formed and seamless woolen sweaters suitable for base layering. The so-called first-line garments are seamless.

"Golden Wool" base sweater

First of all, let me state that the "Golden Wool" base sweater is also a wool base sweater, but the wool fiber used is a master of body feel. That is to say, the wool fiber reaches 15.5 microns, which is softer, waxier and finer than cashmere. Fineness is the most important data that distinguishes wool quality, that is, "count". Just like human hair, the finer the hair, the softer and fluffier it is.

The so-called "golden wool" has a count of 160 (our common better wool has a count of 120), which is comparable to the fiber fineness of cashmere, the comfort and softness of cashmere. , the skin's comfort and warmth are greatly improved. The output is rare and precious. If it has a price, it may not be available. It is rare but not available.

The comfort and fit of a base layer sweater woven from this kind of wool can be imagined.

Out of my preference for handmade products, I started knitting cashmere sweaters by hand after New Year’s Day. I used Consinee’s cashmere thread (the largest cashmere in the country). Compared with the cashmere threads I had knitted before, , the feel is really extraordinary--soft and waxy like clouds.

In order to feel the difference between wool, cashmere and German velvet, I bought different grades of base layer sweaters for comparison.

The above are all my actual feelings and are for everyone to learn from.
