First, dry non-woven fabric
This is a broad category of production methods or product names with the widest range of applications and the longest history of development in nonwovens.
All fibers are formed in the dry state by mechanical, air, electrostatic, or combinations thereof, and then mechanically, chemically, or thermally.
Methods Process or product for reinforcement of non-woven fabrics, collectively known as dry non-woven fabrics.
Second, polymer extrusion nonwoven fabric
Any polymer material that has been processed through extrusion (spinning, meltblowing, film extrusion, etc.) to form a nonwoven structure
Cloth craft or product, collectively referred to as polymer extrusion nonwoven fabric.
Third, wet non-woven fabrics (also known as non-woven papermaking method)
This refers to the use of papermaking methods to form a web in a wet state in which the fibers are suspended in water, followed by mechanical, chemical or thermal methods.
A process or product that is solidified into a non-woven fabric.
Fourth, fiber network (short for fiber network)
This is an intermediate product of nonwovens, which means that the fiber raw material goes through certain means (dry or wet, mechanical, air flow or water
The stream-formed network structure.
Five, into the net
This is the process stage for forming a web and is an important processing step for nonwovens. There are many ways to form a net, such as machinery
Networking, air-laid, water-forming (wet-laid), spunlaid, etc.
Sixth, machinery into a network
The web is formed using a conventional carding machine (for example, a roller card, a flat card) or a saw-tooth opener. This kind of web
Post-processing can be carried out directly or after parallel lay-up or cross-folding.
Seven, airflow into the network
Using aerodynamics, the fibers move in the airstream and eventually deposit as much as possible in a continuous motion.
Holes or dust cages form a web.
Eight, flow into the net
Also known as wet-laid or hydro-formed. Using water as the medium, the short fibers are evenly suspended in water, and water is used as the medium.
The fibers are deposited on a permeable curtain belt or a perforated drum to form a wet web.
Nine, spinning into a net
The filaments formed by the chemical fiber spinning method (melt spinning or solvent spinning, etc.) are directly laid on the motion during the spinning process
The condensing screens are belted to form a web.
This is an important step in the production of non-woven fabrics that gives the web a certain strength and forms a non-woven structure.
The reinforcement can be achieved by mechanical, chemical or thermal methods. Chemical or heat reinforcement mainly through fiber and fiber or fiber
The dimensionality is achieved by the adhesion with the adhesive and can therefore also be referred to as chemical bonding, thermal bonding.
Eleven, mechanical reinforcement
Instead of adhesives, solvents, and other chemical materials, no hot-melt adhesives are used. Instead, the web is made of fiber by mechanical means.
The tangles or webs are reinforced with coiled fiber bundles or yarns.
Twelve, chemical reinforcement
It can also be called chemical bonding. Through the use of adhesives, solvents, and other chemical materials, the fiber in the web due to adhesion
And get reinforced.
13. Thermal reinforcement
The web is reinforced by the hot melt adhesive properties of the thermoplastic material (eg, fibers, powders, films, etc.) in the web.
Both chemical reinforcement and thermal reinforcement can be referred to as adhesion reinforcement.
XIV. Acupuncture Nonwovens
Acupuncture is a major method of mechanical reinforcement of nonwovens. It is used for the repeated wear of the web with a thorn
Spurs cause some fibers to entangle with each other, so that the web is reinforced. Acupuncture nonwovens means the name of this method or product
Fifteen, stitching non-woven fabrics
Stitching is also a major method of mechanical reinforcement of nonwovens. It uses a warp-knitted structure (which can be made of extra yarn
The line or formed from the fibers in the web), reinforcing the web and other materials. Stitching nonwovens means this method or product
16. Spunlaced nonwovens
The spunlace method (also known as spunlace method) is a new method of mechanical reinforcement of nonwoven fabrics. It can also be referred to as needleless acupuncture.
Or spray into cloth method. It uses a very high number of high-pressure water jets to spray the web vertically, making the web partially fibrous.
Entangled and reinforced, the spunlace nonwoven represents the name of the method or product.
Seventeen, impregnation and bonding non-woven fabric
The impregnation and bonding method uses a liquid adhesive, and a variety of padding methods are used to bring the web to an adhesive, which is then dried and baked.
Baking and other processes, so that the web is bonded and reinforced. Immersion bonding nonwovens represent the name of this method or product.
18. Foam Bonding Nonwovens
The foam bonding method, strictly speaking, is also an impregnation bonding method, but it has unmatched by the conventional impregnation bonding method.
Many of its advantages have been rapidly promoted and applied, and it has therefore been separately listed as a chemical bonding method. It is sticky with foam
The mixture is applied to the web, and then dried, baked, and other processes, so that the web is bonded and reinforced. Foam bonding nonwoven
The cloth represents the name of this method or product.
19. Spray-bonded Nonwovens
The spraying and bonding method uses a spraying device to disperse the liquid adhesive into the web, and then it is dried, baked, and the like.
The web is bonded and reinforced. Spray-bonded nonwovens represent the name of this method or product.
Twenty, printing bonding non-woven fabric
The printing adhesive method uses a printing method to apply a liquid adhesive to a web, and then undergoes baking and the like to make the fiber.
The mesh is adhesively reinforced. Printing Bonded Nonwovens means the name of the method or product.
Twenty-one, hot-melt bonding non-woven fabrics
The hot-melt bonding method heats a web containing thermoplastic fibers, powders, or films to make the hot-melt material wholly or partially
Melt to produce adhesive reinforcement. Hot-melt adhesive nonwoven means the name of this method or product.
Twenty-two, hot-rolled bonding non-woven fabrics
The hot-rolled bonding method is a method in which a web containing thermoplastic fibers is heated and pressurized at the same time to make the hot-melt material wholly or partially.
Melt to produce adhesive reinforcement. Hot-rolled bonding nonwovens represent the name of this method or product.
Twenty-three, melt-blown nonwoven fabrics
The meltblowing method is to spray the polymer under high pressure in the molten state and deposit it on the coagulation curtain belt or the roll in the form of very fine short fibers.
The web is formed on the web while it is self-adhesive to form a non-woven fabric. Meltblown nonwovens represent this polymer extrusion
The name of the method or product used to produce the nonwoven fabric.
Twenty-four, film cutting method non-woven fabric
The membrane splitting method is a process in which the polymer is extruded into a film and the film is formed into a net by a mechanical action (for example, cracking, embossing, etc.).
Structure or fibrillated very light non-woven fabric. Film-splitting nonwovens means that the polymer is extruded into a nonwoven fabric
The name of the cloth production method or product. This type of nonwoven fabric is mainly used as a hot melt in lamination processing or hot melt bonding.
Twenty-five, durable non-woven fabric
This refers to non-woven fabrics that can be used multiple times or have a certain service life.
Twenty-six, disposable non-woven fabrics
This mainly refers to non-woven fabrics for single use. In fact, it can sometimes be used more than once, or even up to 4 times.
Twenty-seven, dry papermaking non-woven fabrics
In recent years, a new non-woven fabric technology developed rapidly abroad, its English name is: air-laid-pulp nonwovens, which is based on papermaking raw materials - wood pulp slate as raw material, using air-laid route into the network, and then The name of a production method or product that is consolidated into non-woven fabrics by chemical, thermal bonding, and the like.
