Pure cotton, memory cotton, pearl cotton, which is better?

Hello dear, the uses of these materials are different and there is no comparison.

Pure cotton is suitable for clothing, and it is soft and breathable to fit the body.

Pearl cotton. It is suitable for making insulation materials.

1. Mattress material: The main material of the foam mattress is a mattress made of foam, and the foam materials include: polyurethane foam, high-elastic foam and high-grade memory foam.

The external material of the foam mattress is mostly supplemented by pure cotton, wool, etc. A spring mattress has a core made up of springs. The spring cushion is divided into connected spring mattress, pocket independent spring, and spring system.

Which is better foam mattress or spring mattress 2 Advantages of mattresses: Foam mattresses can fit the curve of the body, while providing support, without losing softness and elasticity, and at the same time can cushion the movement of the body, even if a person turns over frequently, it will not affect the partner, and there is no noise when turning over. Spring mattresses have the advantages of good elasticity, good support, strong air permeability and durability.

The spring mattress is moderately soft and ergonomic, and the pocket freestanding spring provides a comfortable sleep and protects the health of the human spine. The spring system is arranged parallel to the human body, so that any roll on the bed surface will not affect the sleeper next to it. Which is better foam mattress or spring mattress 3 Disadvantages of mattresses:

Disadvantages of spring mattresses: Spring beds with interlocking spring arrangements may cause the cervical and lumbar muscles to be in a state of tension, resulting in neck and shoulder stiffness and lower back pain. In order to fix the internal cushion interlayer, a large amount of super glue is used to fix the internal cushion interlayer, and the interlayer material with up to three layers in the middle is also where dirt and dirt are hidden.

Sponge mattress still has certain shortcomings, sponge mattress air permeability is not good, people in the sleep metabolism of waste, water vapor and so on will continue to be discharged through **, mattress is not breathable, these wastes can not be released in time, is not conducive to human health. Which is better foam mattress or spring mattress 4 The **spring mattress of the mattress is much cheaper than the sponge mattress, and the spring structure is different, and its ** is not the same, **The range is usually between '1000-5000'. Sponge mattresses are generally between '2000-6000'.

5 Foam mattress or spring mattress is better, specifically there is not much difference between the two, but the sponge mattress is more ergonomic and good for the human spine. It is recommended to use a sponge mattress for people with a bad waist, the spring mattress is too soft for developing children to sleep on and not suitable for the elderly. So a sponge mattress is the best choice.

Whether it's good or not depends on the use. Clothes made of polyester are durable, but not breathable; Cotton clothes are breathable, soft, easy to touch, and not durable. Everyone says that if underwear, loungewear or babies wear it, of course, pure cotton is more comfortable, but if it is an industry that requires intense sports, such as mountaineering clothes, sportswear, polyester is better.

Of course, it's a noisy latex pillow.

The head is good, the latex is pure celery, and if the memory foam is a domestically produced liquid bridge, I recommend that you do not buy it, most of them are made of sponge + chemicals, and there is no memory effect. In addition to the functions of antibacterial and anti-mite, breathable and moisture-absorbing, the natural latex pillow also has international certification and long-lasting non-deformation, and has high resilience to maintain a high degree of comfort for your cervical spine. Summer doesn't feel hot in normal conditions.

I used to buy a memory pillow, and the pillow was hard in winter, and I couldn't sleep at all and slept thinner, and then I changed to a good night latex pillow, which was much better than what memory pillow.

Shop pillows.

The pillow is the main tool for maintaining a normal position on the head and neck. This "normal" position refers to the physiological curve that maintains the head and neck segment itself. This physiological curve not only ensures the balance of the external muscles of the cervical spine, but also maintains the physiological and anatomical state within the spinal canal.

Therefore, an ideal pillow should be in line with the requirements of the physiological curvature of the cervical spine, soft texture, good air permeability, high before and low in the back, in line with the shape of the physiological curve of the neck. It should also help the blood flow in the neck, can play a role in awakening the brain and calming the nerves, and can prevent incorrect sleeping posture and avoid shoulder and neck muscle strain. And the height of the pillow must be suitable for the natural curvature of the cervical spine.

Because this shape can use the depression in the middle to maintain the physiological curvature of the cervical spine, it can also play a relative immobilization and fixation role on the head and neck, which can reduce the abnormal activity of the head and neck during sleep.

Secondly, it is also very important to choose the contents of the pillow core, which are commonly used: Buckwheat husk: cheap, good air permeability, and the height of the pillow can be adjusted at any time.

Fluff: soft texture, good air permeability, can be adjusted at any time. Mung bean husk:

Not only is it aerotable, but it is also cool and relieves heat, such as adding a moderate amount of tea or mint, but it is mainly used in summer. Others, such as duck feathers, are also good, but **higher. Memory Foam:

It has the characteristics of temperature sensitivity, and can sense the body temperature of the human body. Memory foam absorbs human pressure. When the human body touches the material, the material will sense the temperature of the human body, gradually become softer, and at the same time absorb the pressure of the human body, so as to adjust the human body to the most comfortable posture.

The pillow should not be too high or too low, do not "sit back and relax", it is better to take the physiological position, generally speaking, the height of the pillow is 8 15cm, or calculated according to the formula: (shoulder width - head width) 2.

I don't know if there is an IKEA supermarket in your city, where you sell all kinds of pillows. It is divided into prone pillows, side pillows, supine pillows, down pillows, pearl cotton and so on. You can try it on the spot, and you will definitely choose a pillow that suits you.

I just bought four of them not long ago, side and stomach, which are very comfortable and the quality of sleep is also good. Originally, I used buckwheat husk, and I felt that my neck was very sore when I slept until midnight, and the back of my head was numb with pain. You can try changing the pillow. ：）

Pillows made of buckwheat husk are better, and the fabric is selected according to the comfort of the human body, and the height of the cotton cloth should not be too high or too low. The person's head rests on it parallel to the cervical vertebrae.

If you arrange it from the ergonomic shape, the memory foam, latex cotton, and TPE that can be shaped are better, and the three-dimensional shape of the ergonomic pillow can be shaped, and it will not be deformed for a long time.

If it is arranged from the aspect of mechanical equalization pressure relief effect, the memory foam material is better, and after absorbing elasticity, it can make the cervical spine more completely relaxed.

If it is discharged from the aspect of hygiene and cleaning, polymer materials such as memory foam and latex cotton are better, and it is not easy to breed mites and bacteria.

Breeding, beneficial**.

It must be pearl cotton. Pearl cotton is a three-dimensional crimped hollow fiber, processed into ball-shaped cotton through a special balling technology, the inside of the cotton ball is hollow, there is a large breathable space, and the warmth and air permeability are stronger. Moreover, after quilting, the product will automatically expand, and will not be deformed even if machine washed.

Mostly used on pillows.

PP cotton: commonly known as: doll cotton, hollow cotton, also known as filling cotton, the material is polyester staple fiber, mainly there are two kinds of general fiber and hollow.

Because the chemical fiber material is not very breathable, it is easy to deform and form lumps after a long time, lack of elasticity, and the pillow is in an uneven state, especially the inferior cotton produced by some small manufacturers for filling. Therefore, it is recommended that you choose the best pearl cotton when buying toys and pillows, as cheap fiber pillows are easy to deform.

The advantages of pearl cotton over PP cotton are good elasticity, strong recovery, and no agglomeration, so pearl cotton is better than PP cotton.

For pillows, I think it will be better to fill in pearl cotton, which has a good fluffy effect, and good elasticity, is softer to use, and pearl cotton is more healthy and environmentally friendly to use, so I think it will be better to choose pearl cotton for cushion filling.

Pearl cotton is recommended.

PP cotton is made of polypropylene artificial chemical fiber, polypropylene (PP) cotton has good elasticity, strong bulkness, beautiful shape, not afraid of squeezing, easy to wash, fast drying. It is suitable for quilt factories, toy factories, spray cotton factories, non-woven fabrics and other manufacturers. It has the advantage of being easy to clean.

Pearl cotton: Polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is made up of low-density polyethylene grease that is physically foamed to produce numerous individual bubbles.

It overcomes the shortcomings of ordinary styrofoam that are brittle, deformed and have poor recovery. It has many advantages such as water and moisture resistance, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance. It is an ideal alternative to traditional packaging materials.

PP cotton chemical fiber material is not very breathable, easy to deform and clump after a long time, lack of elasticity, pillows are in an uneven state, especially the inferior cotton produced by some small manufacturers for filling. Therefore, it is recommended that you choose the best pearl cotton when buying toys and pillows, as cheap fiber pillows are easy to deform.

PP cotton is cheaper, and **pearl cotton is more expensive. The softness of pearl cotton is better than that of PP cotton, and of course it is good to make pillows, but PP cotton is also OK.

The advantages of pearl cotton over PP cotton are good elasticity and no agglomeration.

PP cotton is commonly known as doll cotton, hollow cotton, also known as filling cotton, the material is polypropylene fiber for artificial chemical fiber, cotton elasticity is good, fluffiness is strong, beautiful shape, not afraid of extrusion, easy to wash, fast drying, suitable for clothing factories, toy factories, spray cotton factories, non-woven fabrics and other manufacturers, its advantage is that it is easy to clean.

Pearl cotton, also known as EPE, is composed of low-density polyvinyl ester through physical foaming to produce countless independent bubbles, soft texture, good-looking appearance, with water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, environmental protection and pollution-free advantages, widely used in hardware appliances, instrumentation, computer audio, medical equipment, glass ceramics, furniture, furniture, toys and fruits, daily necessities and other products packaging and express shockproof packaging.

The material of the two is different, the use is not the same, in general, PP cotton is softer, suitable for use as a pillow filler, but some PP cotton will appear clumping after cleaning or use for a period of time, lack of elasticity, pillow uneven phenomenon, so we pay attention to the selection of high-quality PP cotton when buying PP cotton as a pillow core pillow. Compared with PP cotton, pearl cotton is tougher and more able to withstand impact, and is suitable for use as shockproof inner tray packaging of products or sound insulation, heat insulation, aquaculture floating equipment, luggage lining, sporting goods protective pads, etc. The advantages of pearl cotton over PP cotton are good elasticity, no agglomeration, can be recycled many times, good protective performance, strong toughness, and more widely used.

The elasticity of pearl cotton is good, and it is suitable for things such as pillows.

4D cotton is good.

The 4D fabric is high-grade knitted fabric + double-layer absorbent cotton + memory foam. Memory foam underwear is perspiratory, breathable, and not easy to age, no harm to the body, and silicone is not breathable.

Pearl cotton has the function of waterproof and moisture-proof. It has the effect of shock absorption and impact resistance. It has the functions of heat preservation, warmth and sound insulation.

It has good toughness and anti-corrosion. 4D cotton can be washed, but not too often, otherwise it will destroy its fiber structure and protein structure, and the result will be hard and broken.
