Which cotton wool down has a high cold index?

Among the four natural thermal insulation materials of cotton, wool, silk and down, down has the best thermal insulation performance. China's great physician Li Shizhen also mentioned in the "Compendium of Materia Medica": "Choose goose belly fluff for clothing, quilted, soft and new cold, especially suitable to relieve the baby's pain."

From a modern point of view, the health function of duvets is determined by the unique gentle warmth and moisture absorption and good properties of down. From the point of view of warmth, the research results published by French scientific research institutions believe that there is no thermal material in the world that exceeds the thermal performance of down, because natural brand down is a star-like structure, and each down filament can be seen to be fish scales under a magnifying glass, with countless tiny pores.

Contains a large amount of still air, due to the lowest conductivity coefficient of air, the formation of down good warmth, coupled with down and full of elasticity, with a down content of 50% of the down test, its lightness and fluffiness is equivalent to cotton times, wool times, so the duvet is not only soft and warm, but also good touch.

In addition, natural brand down also has good moisture absorption and divergence properties that other thermal materials do not have. According to the measurement, the body of a person continues to emit sweat when sleeping, an adult exudes about 100 grams of sweat overnight, and down can continuously absorb and discharge the sweat released by people, so that the body does not have a feeling of dampness and stuffiness.

Down, structured as a spherical fiber, mainly ducks and geese, close to the abdomen and the muscle growth between the wing nests, is the direct contact part of birds and water, the main function is to keep warm and heat dissipation, the total weight of a duck's feathers is 300 grams, down only accounts for 8-10% of the whole body feathers. The ** of down can be said to be a rare natural warm material, coupled with tens of thousands of small pores densely covered with down ball fibers to absorb the hot air emitted by the human body, isolating the invasion of cold air from the outside to provide the best cold, and the texture of down is very soft and elastic. It is currently the most ideal filling material for warm clothing among natural materials.

The elastic coefficient is the biggest and most attractive feature of down products. Because it integrates the unique warmth functions such as heat preservation, temperature regulation, moisture absorption, breathability, softness and elasticity, such as: chemical fiber, cotton, wool, silk, and other related fiber filling products, after three to five years of use, due to poor fiber bonding and compression resistance, resulting in rapid reduction of elasticity and size reduction, etc., the material degrades quickly, and the thermal insulation and temperature regulation function and product life will also be rapidly reduced, but the down itself is ultra-light and soft three-dimensional spherical, and rich in animal oil, even after decades of repeated use, The thermal insulation function is still the same.

In terms of warmth, cotton, down, and wool clothes are OK, but down jackets are generally filled with duck down, and the clothes are naturally lighter. And the padding of cotton clothes is mostly cotton, so such clothes will be a bit heavy to wear. Wool and cashmere clothes have shrinkage felt, which cannot be washed, and they also love pilling.

Judging from the above points, in the case of strong winds and snow in winter, the down jacket will be very waterproof, so it is also warmer.

Cotton is made of cotton, down is made of feathers of chickens, ducks and geese, and wool is made of sheep hair, compared to down is warmer, so in the winter in the Northeast, many people wear down jackets.

To say that cotton and down and wool clothes are probably very different, because the pure quality of cotton is better, and it is also relatively fat to wear, after all, they all like to lighten clothes now, such as down jackets, although this kind of clothes look lighter, but the warmth effect is also very good.

Cotton, down, wool clothes have such a difference, he generally wears more bloated, down is generally lighter, generally more close-fitting, I personally think that down will be more warm, in winter often wear down jackets, so I personally think that down is warmer.

Compared with wool, down jackets will be warmer than wool.

Down jackets depend on the down content and the number of grams of down, generally 90-59% of the down, about 200 down is also very warm, the bigger the down grams.

Warm. But in general, down jackets are better at keeping out the cold than wool.

The best is the white goose.

Down, followed by gray goose down, then white duck down, and most importantly, gray duck down. If a down jacket is made of better down material and has high fluffiness, the warmth will be better.

Summary. The warmth coefficient of camel hair is slightly higher than that of wool, and the difference is not much. But wool has a very fatal flaw, that is, after a period of use, it will be compacted, glued, stiff, and cannot be fluffy like camel hair for a long time, wool can produce felt.

This greatly affects the warmth, breathability, and softness of the wool quilt, as well as the feel and comfort of the wool quilt.

Wool, cashmere, camel hair. Which one is better for warmth.

Hello, it's an honor for me to answer your questions, it will take a little time to sort out the answers, please be patient

Hello, 100% made of camel hair is warmer than wool, cashmere is lightweight and suitable for the south, wool is not easy to deform, not too soft. Camel hair is very soft and warm, making it suitable for northerners.

The warmth coefficient of camel hair is slightly higher than that of wool, and the difference is not much. But wool has a very fatal flaw, that is, after a period of use, it will be compacted, glued, stiff, and cannot be fluffy like camel hair for a long time, wool can produce felt. This greatly affects the warmth, breathability, and softness of the wool quilt, as well as the feel and comfort of the wool quilt.

The above is all my reply, I hope it can help you and I wish you a happy life

The down jacket is warm, and it is better to wear a down jacket when it is cold. Down is by far the best natural material used for human warmth, and after washing, drying, grading and other processes, it is made into down jackets. Compared to man-made materials, down has three times the warmth of ordinary man-made materials.

Down jackets are light, soft and warm. A down jacket made of nylon silk with a dough and lining has a total weight of between 500 1000 grams, which is 1 6 to 1 2 of the weight of other warm clothing. Because the down is soft, it is used as a wadding material for clothes, and it is comfortable to wear.

Down is not susceptible to fibre cementation;The fabric is mostly made of high-density coated fabric, which can keep more air in the garment, so it has good thermal performance. The cashmere content in the cashmere coat is limited, and the warmth effect is not as good as that of the down jacket, but wearing a cashmere coat is more formal, decent, and beautiful to wear.

Space cashmere sweater warmth principle.

What is the warmest in winter, some people say down jackets and some people say cashmere sweaters. When it comes to cashmere sweaters, the first problem that comes to everyone's mind is "expensive". A good cashmere sweater is not an ordinary expensive, but tens of thousands.

The average one is several thousand, and the average person is reluctant to buy it to wear. I'm also shy away from cashmere sweaters, just take a look. How warm and good is the cashmere sweater, and it is also known as a soft **.

Cashmere is a layer of fine, rich fluff that grows at the root of goat hair to protect against the cold in the harsh winter. The colder the weather, the richer the velvet and the longer the fiber growth. Therefore, cashmere sweaters processed with cashmere fibers have strong warmth.

Absorbent and comfortable to wear. Cashmere's moisture absorption capacity is the strongest of all fibers, with a moisture regain rate of around 15%. The cashmere sweater can automatically absorb moisture under the conditions of changeable outside temperature, has a good perspiration effect, and quickly and automatically adjusts the temperature suitable for skin physiology with the human body.

First of all, the first point is to compare the difference between the two types of clothing insulation materials. Everyone is familiar with down jackets, and the most important thing in making down jacket bags is the down filled inside. In general, down is graded, the best is white goose down, followed by gray goose down, then white duck down, and the most inferior is gray duck down.

If a down jacket has a better down material and high fluffiness, the warmth will be better.

The wool coat is divided into grades, and the best cold-proof is actually the cashmere coat, followed by the wool, and finally the woolen coat. If it is a cashmere coat, it can not better fix the cold air, resist the invasion of cold air, be more frost-resistant, and the fluffiness and softness are also very good, but this kind of cashmere coat that is really cold-proof and frost-resistant ** is not cheap, because the output of cashmere is very small.

The difference in the degree of wind resistance.

Secondly, my cousin at the clothing store told me to take a look at the windproof properties of these two types of clothes. Most of the outer layers of down jackets will be covered with windproof and waterproof coatings, which can prevent the inner down from drilling out, and secondly, it can better keep warm. A good wool coat has a very tight and thick fabric, but there are still some deficiencies compared to the waterproofing of a down jacket.

The difference between thermal storage and thermal insulation.

The third point is to look at the difference between these two types, a kind of heat storage and heat preservation. My cousin in the clothing store told me that the down jacket has a good heat storage and thermal insulation effect because it is filled with a lot of air inside, which can isolate the heat in our body from the cold air outside; The wool coat is simply isolated by the thickness of the cashmere, so that the heat does not escape. So compared to down jackets and cashmere coats, it is still not warm enough.

If you want to ask about cold and frost resistance, down jackets still have the upper hand! Of course, if your area is not cold in winter, wearing a better cashmere coat is enough to keep warm, and it will look more fashionable, but the only bad point is that the wool coat is particularly inconvenient to clean, so friends who love beauty should pay attention to it.

It mainly depends on the windproof and warmth, the clothes with good windproof will be very warm, but the thickness is also quite important, depending on personal hobbies, there is that kind of wool is also very warm, depending on the wool content. The down jacket is mainly to see the inner liner, and the duck down jacket is mainly to see the amount of duck down, the higher the content, the better, generally speaking, white duck down will be better.

In fact, I think down jackets are warmer than wool. Because there are a lot of gaps between the padding and down in the down jacket, these gaps make him warmer.

Of course, the wool should be kept warm, but the wool is too broken, and if it is not handled well, it smells, and it is everywhere.

Down jackets are warm, and cardigans look good.

Cotton, wool, and down are actually very good at keeping out the cold, depending on whether the material you use is good, for example, a thick cotton jacket is warmer than a thin down jacket.

The down jacket is filled with feathers, and the cotton is filled with cotton, and the warmth effect of down is better than that of cotton.

Down is animal hair, cotton is grown by plants, the cost of down is higher, and the warmth will be better than cotton.

Unlike down and cotton, which are used as fillers in clothes, they are very light and warm. It can also be washed, but cotton as a filler can not be washed, once washed, the cotton is very easy to harden in the knot, and it will be unevenly distributed in the clothes, resulting in a piece of east and west, so it is not warm.

Down is a commonly used filling in winter clothes, it is lighter and thinner than cotton, has a better warmth effect, and is more comfortable to wear.

Cotton, cashmere, and down are the three substances that have the largest cold index, and I think that this one is definitely a little better than the cold index of wool.

Cardigans and down jackets have different warmth effects, and down jackets have a slightly better warmth effect. Down jackets generally account for more than half of the amount of duck down, and at the same time, some fine feathers can be mixed with the duck down, the duck down is cleaned, sterilized at high temperature, and then filled in the clothes is the down jacket. Down jackets have the best warmth.

It is mostly worn by people in cold regions, and is also commonly used by polar expeditions.

The most common fillings in down jackets are goose down and duck down, which can be divided into white down and gray down according to color. The down jackets on the market are sorted according to **: white goose down, gray goose down, white duck down, and gray duck down.

It may be affected by the ranking of selling prices, so many people think that these fleeces are also sorted in this way in terms of quality, but in fact, they are not. Through theoretical research and practical experience in down, generally speaking, goose down with the same quality and down content is better than duck down in terms of warmth and fluffiness, but the color has little to do with the quality of down jackets.

It's all good, but the down jacket is even better.
