1. Dry non-woven fabric
This is the largest production method or product name for nonwovens in the widest range of applications and the longest history.
Any fiber in the dry state is formed into a web by mechanical, airflow, static electricity or a combination thereof, and then mechanically, chemically or thermally.
A process or product in which a nonwoven fabric is reinforced by a method, collectively referred to as a dry nonwoven fabric.
Second, polymer extrusion non-woven fabric
Any polymer material is processed into a mesh structure by extrusion (spinning, melt blowing, film extrusion, etc.)
The process or product of the cloth, collectively referred to as a polymer extrusion nonwoven.
Third, wet non-woven fabric (also known as paper-making non-woven fabric)
This refers to the fact that the fibers are suspended in water in a wet state, which is formed into a net by papermaking, and then mechanically, chemically or thermally.
A process or product that is solidified into a nonwoven fabric.
Fourth, the fiber network (short for fiber network)
This is an intermediate product of non-woven fabrics, which refers to the fiber raw materials through certain means (dry or wet, mechanical, air or water)
The network structure formed by the processing of the stream).
Five, into the network
This is the stage of the process of forming the web, which is an important processing step of the nonwoven fabric. There are many ways to form a net, such as machinery.
Forming the net, forming the air into the net, forming the net into a net (wet-laid), spinning into a net, and the like.
Six, mechanical network
The web is formed by a conventional carding machine (for example, a roller carding machine, a cover carding machine) or a sawtooth opening machine. This type of web
It can be directly post-processed, or it can be post-processed after parallel lay-up or cross-folding.
Seven, airlaid
Using aerodynamics, the fibers move in the airflow and finally deposit as much as possible in a continuous motion
On the curtain belt or dust cage, a web is formed.
Eight, the water flows into the net
Also known as wet-laid or hydro-laid. Using water as a medium, the short fibers are uniformly suspended in the water, and the water flow is used as a medium.
The fibers are deposited on a permeable curtain or perforated drum to form a wet web.
Nine, spinning into a net
The filament formed by the chemical fiber spinning method (melt spinning or solvent spinning, etc.) is directly laid on the spinning process during the spinning process.
The net curtain is attached to form a web.
Ten, reinforcement
This is an important process in the production of nonwoven fabrics to give the web a certain strength to form a nonwoven fabric structure.
Reinforcement can be achieved by mechanical, chemical or thermal methods. Chemical or thermal reinforcement mainly through fibers and fibers or fibers
Dimensions are achieved by adhesion to the adhesive, and thus may also be referred to as chemical bonding or thermal bonding.
XI. Mechanical reinforcement
No chemical materials such as adhesives, solvents, etc., or hot melt bonding means, but mechanical means to make the fiber in the fiber
Dimensional entanglement, or reinforcement of the web with coiled fiber bundles or yarns.
Twelve, chemical reinforcement
Also known as chemical bonding. By using chemical materials such as binders and solvents, the fibers in the web are bonded.
And get reinforced.
Thirteen, heat reinforcement
The web is reinforced by the hot melt adhesion characteristics of thermoplastic materials (e.g., fibers, powders, films, etc.) in the web.
Both chemical and thermal reinforcement can be referred to as bond reinforcement.
Fourteen, needle punching nonwoven fabric
Needle punching is a major method of mechanical reinforcement of nonwovens. It is pierced and worn repeatedly for the web.
The thorns cause some of the fibers to entangle each other, and the web is reinforced. Needle-punched nonwovens indicate the name of the method or product
Said.
Fifteen, stitching non-woven fabric
Stitching is also a major method of mechanical reinforcement of nonwoven fabrics. It is a warp-knitted coil structure (can be made of additional yarn)
Lines or fibers formed from the web) are used to reinforce materials such as webs. Stitched nonwoven fabrics represent such methods or products
The name.
Sixteen, spunlace nonwoven fabric
The spunlace method (also known as spunlace) is a new method for mechanical reinforcement of nonwoven fabrics. It can also be called needle-free needle-punching.
Or spray water into a cloth. It uses a very fine high-pressure water stream to spray the web vertically, so that the web is partially fiber-phase
Reinforced by intertwining, spunlaced nonwovens indicate the name of the method or product.
17. Impregnating and bonding non-woven fabric
The immersion bonding method is to use a liquid binder to carry the binder to the web through various padding methods, and then to dry and bake.
The process of baking and the like allows the web to be bonded and reinforced. The dip-bonded nonwoven fabric represents the name of the method or product.
18. Foam bonding non-woven fabric
The foam bonding method, strictly speaking, is also an immersion bonding method, but it has no conventional immersion bonding method.
Many of the advantages are rapidly being promoted and applied, so it has been separately listed as a chemical bonding method. It is sticky with foam
The mixture is applied to the web, and then subjected to drying, baking and the like to obtain the bonding reinforcement of the web. Foam bonding non-woven
Cloth indicates the name of this method or product.
Nineteen, spray bonding non-woven fabric
The spray bonding method uses a spraying device to disperse the liquid binder into the web, and then dry, bake, and the like.
The web is bonded and reinforced. Spray bonded nonwovens indicate the name of the method or product.
Twenty, printing and bonding non-woven fabric
The printing bonding method is a printing method in which a liquid adhesive is applied to a web, and then baked to form a fiber.
The mesh is bonded and reinforced. A printed bonded nonwoven fabric indicates the name of the method or product.
Twenty-one, hot melt bonding non-woven fabric
Hot melt bonding method is to heat a web containing thermoplastic fibers, powders or films to make all or part of the hot melt material
Melt to produce adhesion reinforcement. A hot melt bonded nonwoven fabric indicates the name of the method or product.
Twenty-two, hot-rolled bonded nonwoven fabric
The hot-rolling bonding method is to heat and press the fiber web containing the thermoplastic fiber to make the hot-melt material wholly or partial.
Melt to produce adhesion reinforcement. Hot rolled bonded nonwovens represent the name of this method or product.
Twenty-three, melt-blown nonwoven fabric
The melt-blown method is to spray the polymer under high pressure in a molten state, and deposit it in a very fine short fiber form on the condensation curtain belt or roll.
The cylinder is formed into a net while being bonded to form a nonwoven fabric. Meltblown nonwovens indicate such polymer extrusion
The name of the production method or product of the nonwoven fabric.
Twenty-four, film cracking nonwoven fabric
The membrane splitting method is to form a web by mechanical action (such as needle splitting, embossing, etc.) in the stage of polymer extrusion and film formation.
A very lightweight nonwoven fabric that is fibrillated or fibrillated. Membrane-cleaved nonwoven fabric means that the polymer is extruded into a non-woven fabric.
The name of the production method or product in which the fabric is made. This type of nonwoven fabric is mainly used for hot melt in lamination processing or hot melt bonding.
Bonding medium.
Twenty-five, durable non-woven fabric
This refers to a nonwoven that can be used multiple times or has a certain useful life.
Twenty-six, disposable nonwoven fabric
This mainly refers to non-woven fabrics for single use. In fact, it can sometimes be used more than once, even up to 4 times.
5 times.
Twenty-seven, dry paper non-woven fabric
In recent years, a new non-woven fabric technology developed rapidly in foreign countries, its English name is: air-laid-pulp nonwovens, which is based on papermaking raw materials - wood pulp rafts, using air-laid routes into a network, and then The name of a production method or product that is reinforced into a nonwoven fabric by chemical, thermal bonding, etc.
