How warm is polyester? Does polyester keep warm

Polyester is polyester, and the warmth performance is far from being comparable to duck down!

Polyester is characterized by being strong, wear-resistant, and durable. However, the water absorption and air permeability are very poor, and the warmth is very average, not even as good as cotton, let alone compared with duck down.

Duck down is light, breathable, fluffy, and generally better than polyester fiber in terms of warmth. Of course, the thermal insulation performance of polyester fibers in different processes is also different, and now the six-hole and nine-hole polyester fibers often said on the market have good thermal performance. In addition, the finer the polyester fiber, the better its thermal performance.

It cannot be said that the thermal insulation performance of polyester fiber must not be as good as duck down, and now the thermal insulation fiber developed by DuPont and 3M has done a very good job in thermal performance, which is basically comparable to down. The key lies in the process and post-processing of polyester fiber production.

Not good, the eiderdown is very warm.

Polyester does not keep warm.

Polyester fiber has many excellent textile properties and taking properties, a wide range of uses, can be pure weaving, can also be blended with cotton, wool, silk, hemp and other natural fibers and other chemical fibers blended and intertwined, made into a variety of colors, firm and crisp, easy to wash and dry, iron-free and washable wearable performance of imitation wool, imitation cotton, imitation silk, imitation linen fabric.

Polyester fabrics are suitable for men's and women's shirts, outerwear, children's clothing, upholstery fabrics and carpets, etc. Since polyester has good elasticity and fluffiness, it can also be used as wadding.

In industry, high-strength polyester can be used as tire cords, conveyor belts, fire hoses, cables, fishing nets, etc., and can also be used as electrical insulating materials, acid-resistant filter cloths and papermaking blankets. Non-woven fabrics made of polyester can be used for interior decorations, carpet base fabrics, pharmaceutical industry fabrics, flocting, lining, etc.

Pros: Polyester fibers have high strength and elasticity, so they are durable, wrinkle-resistant, and do not iron. Its lightfastness is better than that of acrylic fibers, and its lightfastness is better than that of natural fiber fabrics, especially the lightfastness after glass fibers is almost equivalent to that of acrylic fibers.

In addition, polyester fabrics have good resistance to various chemicals, and acid and alkali damage to them is small, and they are not afraid of mildew or insect damage.

Disadvantages: First of all, the hygroscopicity of polyester fiber is poor, the water absorption is not strong, the melt resistance is poor, and it is easy to absorb dust, which is due to its texture; Then there is poor air permeability, which is not easy to breathe; Finally, its dyeing performance is poor, and it needs to be dyed with disperse dyes at high temperatures.

Polyester fabricis made from organicDiacidsand diol polycondensation polyester to produce synthetic fibers obtained by spinning, which is warm.

The fiber molecular structure of polyester fiber is relatively tight, with the characteristics of impermeability, in the cold weather can resist the invasion of the cold wind, play a role in warmth, so polyester fiber has a certain vertical warmth, some winter clothes on the market are made of polyester fiber material.

Polyester fiber has a certain amount of warmth, and it can play a role in keeping out the cold in winter. Moreover, the material of polyester fiber itself has very good wear resistance and corrosion resistance, a long service life, low quality, and good cost performance.

Disadvantages of polyester fibers:

1. Poor hygroscopicity, stuffy wearing, and easy to carry static electricity and dirty dust, which affects the appearance and comfort.

2. Polyester fabric.

The melt resistance is poor, and it is easy to form holes in soot state, spark, etc. Therefore, polyester fabrics.

When wearing, try to avoid contact with cigarette butts, sparks, etc.

The warmth was ok. The fiber molecular structure of polyester fiber is relatively tight, with the characteristics of non-breathability, in the cold weather can resist the invasion of the cold wind, play a role in warmth, so polyester fiber has a certain warmth, some winter clothes on the market are made of polyester fiber material.

Polyester fibers are synthetic fibers made from polyester condensed by organic diacids and diols. Polyester is commonly known as polyester, which is widely used in clothing fabrics, polyester has excellent wrinkle resistance, elasticity and dimensional stability, good insulation performance, and is very widely used, suitable for men, women and children.

Polyester fibers have high strength and elastic recovery, so they are strong and durable, wrinkle-resistant and iron-free. Its lightfastness is good, in addition to being worse than acrylic, its lightfastness is better than that of natural fiber fabrics, especially behind the glass The lightfastness is very good, almost comparable to acrylic. In addition, polyester fabrics are resistant to various chemicals, and acids and alkalis are not very damaging to them, and they are not afraid of mold or insects.

Polyester disadvantages:

1. Polyester fiber has low hygroscopicity (does not absorb sweat), and is not suitable for inner flowers.

2. Polyester fiber is easy to feel static electricity, so the fabric is easy to get wet and fluffy.

3. Polyester fiber has poor alkali resistance.

4. Poor dyeing performance of polyester fiber.

5. The abrasion resistance of polyester fiber is poor.

6. Polyester fiber is easy to melt, and it is easy to form small holes in the fabric in case of unextinguished sparks.

Polyester fibers are warmer.

1. Polyester fiber is a kind of synthetic fiber, its advantages are obvious, it is wear-resistant, durable, elastic, has excellent wrinkle resistance and is easy to take care of, and the color fixing effect is very good, so the quilt of polyester fiber is generally brightly colored, the color is very beautiful, and it can meet the needs of various quilt appearances.

2. The polyester quilt can be directly machine washed, spun and dried, which is very convenient.

3. The thermal insulation performance of polyester fiber quilts is also good compared with cotton quilts, and the weight is lighter.

4. The polyester fiber quilt is not afraid of pressure and easy to keep.

5. Polyester fiber quilts have a common disadvantage of polyester fiber products, that is, they are easy to generate static electricity in a dry environment.

The difference between polyester and cotton

1. Raw materials. Polyester fiber: Polyester fiber is a modified polyester fiber, which is made of spinning and post-treatment.

Cotton: A fabric made from cotton.

2. Breathability and heat resistance.

Polyester fiber: poor air permeability, poor melt resistance, easy to form holes in case of soot, sparks, etc.;

Pure cotton: the fabric has good moisture absorption and heat resistance, heat and alkali resistance, health and hygiene; When concentrated sulfuric acid stains the cotton cloth, the cotton cloth is burned into holes.

3. Wrinkle resistance and shape retention.

Polyester fiber: wrinkle-resistant, iron-free, lightfast, durable, non-sticky hair.

Pure cotton: easy to wrinkle, easy to shrink, easy to deform, easy to stick to hair.

This is not comparable, and it has to do with the organization and finishing of the fabric.

Polyester fiber, also called polyester, some thermal underwear is fleece, these fleece are polyester, and it is relatively warm to wear.

And cotton is generally made of jersey, cotton wool cloth, etc.

Cotton is hotter, I know when I buy pants in summer, with cotton with a high proportion of stuffy will be more stuffy, and polyester fiber materials like sweatpants will be drier and ......

If it's not specific, there's really no way to compare.

From the perspective of cotton clothes and quilts, polyester is lighter than cotton at the same thickness. If it is the same weight, it is still warmer than polyester.

Hello, kiss the polyester fiber to keep warm. The fiber molecular structure of polyester fiber is relatively compact, not breathable, and wearing polyester fiber clothes in winter can touch the pure resistance to the cold wind and stove state of the hidden noise source, and can keep warm, which is the reason why polyester fiber keeps warm. Most down jackets and cold clothing are made of polyester.

Not warm. In fact, although polyester fibers are more tightly arranged, they are not as warm as down.

After comparison, it can be found that polyester fiber and down are two materials, under the same unit area and thickness, polyester fiber is warmer, because polyester fiber is woven more tightly and closely.

However, most of the polyester fabrics on the market are much thinner than down products. Therefore, the thermal insulation effect of the two garments is still different, and some thickened down garments are relatively warmer. Of course, because of this, you still have to choose according to your needs.

We know that polyester fiber is a synthetic chemical fiber, one of which is polyester, and the fabric made of polyester fiber is one of the commonly used fabrics for clothing, which is not only wear-resistant, but also quite durable. Of course, polyester fiber is actually a more commonly used filling material, especially pillows, toys, quilts, can be used as a material. In general, polyester fibers are white and curly.

With the improvement of the production process, in order to obtain a warmer and fluffier function, many factories have now begun to produce hollow polyester fibers, simply put, each polyester fiber is hollow, so that the middle of the polyester fiber can store air, so it greatly improves the thermal performance of polyester fiber, and gradually produces polyester fibers with seven holes, nine holes or even more holes, just like lotus root, the middle is all holes, which greatly increases the air storage space.

For down, from the current market, in fact, down is the down obtained from ducks and geese, so it is also called duck down and goose down. It is worth noting that the quality of down is much higher than that of feathers, and generally down is taken as down, and feathers are mainly used as fillers. Of course, down has very good thermal insulation performance, which is the best of all thermal materials.
