This materia is widely known as a mask material, so do you know that this material has other uses besides masks? What is the difference between hot air cotton and needle-punched cotton? What is es hot air cotton? Let’s take a look at it next.
The use of hot air cotton
This material has many uses. It is used in various fields according to density. It can be used in fabrics for baby diapers, adult incontinence pads, feminine hygiene products, napkins, bath towels, disposable tablecloths. as well as filter materials, sound insulation materials, shock absorption materials, etc.
The difference between hot air cotton and needle-punched cotton
1. From the point of view of raw materials and craftsmanship.
This materia is made of es fiber, and acupuncture cotton is made of polyester fiber. Compared with polyester fiber, es fiber is smoother and softer. , commonly used in baby diapers, sanitary products, folding masks, etc. Needle-punched cotton is relatively high in weight and density and is mostly used in clothing, heaters, and shaped masks. Because of its high density, it can be shaped at high temperatures.
2. From the technical point of view
The hot-air cotton adopts a net-laying oven, and the needle-punched cotton adopts the acupuncture process. From the appearance point of view, the hot-air cotton will be smoother. If you observe it carefully, it can be seen by the naked eye that multiple layers of fiber cotton are bonded together. Acupuncture cotton is a synthetic fabric that is held by needles with multiple needle boards countless times. If you look closely, you can find that countless small pinholes are densely covered, and the name of acupuncture cotton is also derived.
What is ES hot air cotton?
es hot air cotton is a new type of non-woven material, which is made by opening, carding, and hot pressing. In labor protection masks, diapers, sanitary napkins, adult nursing pads, eye masks, etc.
Is there a difference between es hot air cotton and hot air cotton?
This material belongs to a kind of hot air bonding (hot rolling, hot air) non-woven fabrics. spinning. From this, we know that hot air cotton is a process called, then, what is the difference between es hot air cotton non-woven fabric and hot air cotton?
Because the names of various industries are different, there is no unified name. Hot air cotton usually includes es hot air cotton non-woven fabrics with a heavier gram weight and hard cotton with a fluffy thickness and a harder texture.
Hot air cotton is a process called, es hot air cotton non-woven fabric can be made lower in gram weight and very soft. It is widely used in mask filtration and baby diapers, and general hot air cotton is used in equipment filtration and filling.
es hot air cotton non-woven fabric has high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability and water permeability. It is often used as a filling material for Kn95 folding masks, which plays the role of thermal insulation, moisture-proof and moisture-proof, and improves the wearer. comfortability.
Characteristics of ES hot air cotton
The core material of the mask is none other than Meltblown Nonwoven Fabric. No matter what kind of mask it is, it needs a material that really filters, or a Meltblown Nonwoven Fabric, which was irreplaceable before. But in addition to Meltblown Nonwoven Fabric, there is another material that is the core material of folding masks, which is indispensable. It is ES hot air cotton.
Before understanding this facemask material, let’s first understand its raw material ES fiber. “ES” in hot air cotton is a kind of composite fiber, which is the abbreviation of “Ethylene-Propylene Side By Side” in English, which refers to the name of the raw material. As a new type of thermally-bondable composite fiber, ES fiber has gained a high reputation in the world. Among them, the “hot air” of This material refers to a process. After the fibers are combed, the hot air on the drying equipment is used to penetrate the fiber web, so that it is heated and bonded to form a non-woven fabric.
ES hot air cotton, because of its unique characteristics, is widely used, mainly used in mask filtration, baby diapers, adult incontinence pads, disposable tablecloths, etc. It is an environmentally friendly filling material. It has the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability, and water permeability. ES hot air cotton is generally used for filling in folding masks, which has the functions of thermal insulation, moisture resistance, and moisture resistance, and is conducive to improving the comfort of wearing.
As one of the KN95 folding mask materials, This material is not well known to the public. As a new type of mask material, hot air cotton non-woven fabric itself is widely used in N95 folding masks. Recently, ES hot air cotton has become a hot search headline, so what is ES hot air cotton? What does it do?
1. What is ES hot air cotton?
Hot air cotton is also called tuyere cotton. Hot air cotton is different from spray cotton. Its fixing method is not to use latex, but to mix a certain amount of low-melting fiber or ES bicomponent fiber in the raw material. After heat drying in the production process, the fibers are fused together, so it also belongs to synthetic fiber filter cotton. of them.
“ES” in ES hot air cotton is a kind of composite fiber, which is the abbreviation of “Ethylene-Propylene Side by side” in English, which refers to the name of the raw material. ES fiber is highly regarded in the world as a new type of thermally bondable composite fiber. Among them, the “hot air” of hot air cotton refers to a process. After the fibers are combed, the hot air on the drying equipment is used to penetrate the fiber web, so that it is heated and bonded to form a non-woven fabric.

3. Features of ES hot air cotton
When the carded web is thermally bonded by calendering or through-air, the low-melting component forms melt bonds at the intersections of the fibers. After cooling, the fibers at the non-intersecting points remain in their original state, which is a form of “point bonding” rather than “zone bonding”, so the product has the following characteristics:
1. Pure white, fluffy, soft feel, good elasticity, strong warmth retention, good moisture absorption, and breathability.
2. The use of natural flame retardant fibers, and no droplet phenomenon. Has a permanent self-extinguishing effect.
3. A dense carbonized layer is formed during combustion. and low carbon dioxide content, only a small amount of non-toxic flue gas is produced.
4. Stable anti-acid and anti-alkali, non-toxic, do not produce any chemical effect. The product is naturally degradable and meets environmental protection requirements.
5. Disadvantages of This material: low strength, easy to deform.
4. ES hot air cotton production process
This facemask material production process: blending-opening-cotton feeding-pre-carding-laying-main carding-hot-air drying-rolling-slitting
Mixed cotton: Proportion of various fibers, mixed fibers;
Initial opening: The mixed raw materials are transported to the pre-opening machine for preliminary loosening and opening;
Fine opening: The fiber raw material prepared by the pre-opening machine is finely opened here, so that the curled fibers are all stretched out for carding;
Collecting cotton: The air duct transports the finely opened raw materials to the cotton collecting machine, where the raw materials after opening are fluffy and soft;
Carding: The cotton collector sends the finely opened doll cotton to the carding machine, and the carding machine will card the fibers into a net shape;
Laying: The carded cotton is laid to the specified width and thickness according to the parameters;
Hot pressing: The cotton laid into a mesh is pressed to a specified thickness according to the specified parameters, and the fibers are initially shaped and entered into the oven, and the hot pressing is completed;
Shaping: The fibers after hot pressing are sterilized by high temperature according to the specified parameters and pressed into the specified thickness. (The two steps of hot pressing and setting are slightly different from the acupuncture process, pay attention to the distinction)
Trimming: According to the specified parameters, the environmental protection resin cotton is cut into the specified width or sheet size, the goods are packaged, and the production is completed.
5. Application of ES hot air cotton
ES hot air non-woven fabric can be used in various fields according to the density, and the general thickness is used for KN95 protective masks, baby diapers, adult incontinence pads, fabrics for women’s hygiene products, napkins, bath towels, disposable tablecloths, etc.; thick products are used for making Cold clothing, bedding, baby sleeping bags, mattresses, sofa cushions, etc. High-density hot melt adhesive products can be used to make filter materials, sound insulation materials, shock absorption materials, etc.
6 Can ES hot air cotton replace Meltblown Nonwoven Fabric?
1 ton of This material can be used to make about 600,000 KN95 and N95 folding masks.
Due to the increase in the demand for masks, one of the raw materials required for the production of masks, Meltblown Nonwoven Fabric, is also in short supply. Since the supply of Meltblown Nonwoven Fabric is so tight, can we use hot air cotton for masks with filtering effect instead?
Everyone knows that “Meltblown Nonwoven Fabric “, an important raw material for the production of masks, is commonly known as the “heart” of masks. It has good filterability, shielding, heat insulation, and oil absorption, and can filter out viruses attached to body fluids. It mainly plays a filtering role in KN95 masks and is an indispensable filter material for masks.
The hot air cotton non-woven fabric, also known as filter cotton, only achieves the primary filter effect, so it cannot replace the melt-blown cloth. Since hot air cotton non-woven fabric cannot replace Meltblown Nonwoven Fabric, what role does it play in KN95 masks? Is it missing material?
Hot air cotton non-woven fabric belongs to a kind of filling material in KN95 masks, taking into account the effects of warmth and protection. The hot air cotton non-woven fabric with high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability, and water permeability is sandwiched in KN95 In the middle of the folded mask, it mainly plays the role of thermal insulation, moisture-proof and moisture-proof, and improves the comfort of the wearer.
Although hot air cotton non-woven fabrics cannot replace Meltblown Nonwoven Fabric, both are KN95 mask materials and are indispensable.
