4. Fiber web (short for fiber web)
This is an intermediate product of non-woven fabrics, which means that the fiber raw materials go through certain methods (dry or wet, mechanical, airflow or water)
Flow).
V. Networking
This is the process stage of forming the fiber web and an important processing step of the nonwoven fabric. There are many ways to form a web, such as machinery
Netting, air-laid, water-laid (wet-laid), spinning, etc.
6. Mechanical netting
Use a traditional carding machine (such as roller carding machine, cover carding machine) or sawtooth opener to form the web. This web
It can be directly post-processed, or it can be laid in parallel or cross-folded.
Seven, air-laid
Using the principles of aerodynamics, the fibers are moved in the airflow, and finally deposited as uniformly as possible in the continuous movement
A fiber web is formed on the hole curtain belt or the dust cage.
8. Water flow into the net
Also known as wet-laid or hydraulic-laid. Using water as the medium, the short fibers are evenly suspended in the water, and the water flow is used as the
In order to deposit the fibers on the water-permeable curtain belt or porous roller 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 in motion during the spinning process
On the belt of the condensed net curtain, a web is formed.
Ten, reinforcement
This is an important process in the production of non-woven fabrics to give the web a certain strength and form a non-woven fabric structure.
Reinforcement can be achieved by mechanical, chemical or thermal methods. Chemical or thermal reinforcement mainly through fiber and fiber or fiber
The bonding between the dimension and the adhesive is achieved, so it can also be called chemical bonding or thermal bonding.
11. Mechanical reinforcement
No chemical materials such as adhesives, solvents, or hot-melt bonding are used, but the fiber in the web is mechanically made
Dimensional entanglement, or use coil-like fiber bundles or yarns to strengthen the web.
12. Chemical reinforcement
It can also be called chemical bonding. Through the use of adhesives, solvents, and other chemical materials, the fibers in the web are bonded
And get reinforced.
Thirteen, thermal reinforcement
Through the hot melt adhesive properties of thermoplastic materials (such as fibers, powders, films, etc.) in the web, the web is strengthened.
Both chemical reinforcement and thermal reinforcement can be referred to as adhesive reinforcement.
14. Acupuncture nonwoven fabric
Needle punching is a main method of mechanical reinforcement of nonwoven fabrics. It is worn repeatedly against the web with barbed
The thorns make some fibers entangle with each other, so that the web is reinforced. Needle punched nonwoven fabric indicates the name of this method or product
Said.
Fifteen, stitch-bonded non-woven fabric
Stitch knitting method is also a main method of mechanical reinforcement of non-woven fabrics, which uses warp knitting coil structure (which can be
The thread may be formed by fibers in the fiber web) to reinforce the fiber web and other materials. Stitch-bonded non-woven fabric means this method or product
The name.
16. Spunlace nonwoven fabric
The spunlace method (also known as spunlace method) is a new method for mechanical reinforcement of nonwoven fabrics, and it can also be called needleless needle punching method
Or spray water into cloth. It uses a very thin high-pressure water flow to spray the web vertically, making the web
They are entangled and reinforced. The spunlace nonwoven fabric indicates the name of this method or product.
17. Impregnated non-woven fabric
Dipping and bonding method is to use liquid adhesive, through a variety of padding methods, make the fiber web with adhesive, and then dried and baked
Baking and other processes, so that the web can be bonded and strengthened. The impregnated bonding method of nonwoven fabric indicates the name of this method or product.
18. Foam bonded non-woven fabric
Foam bonding method, strictly speaking, is also a kind of dipping bonding method, but it is incomparable with traditional dipping bonding method
Many of its advantages have been rapidly promoted and applied, so it has been listed separately as a chemical bonding method. It is sticky with foam
The mixture is applied to the fiber web, and then dried, baked, etc., so that the fiber web is bonded and strengthened. Foam bonded nonwoven
The cloth represents the name of this method or product.
Nineteen, spray bonding method non-woven fabric
The spray bonding method is to use a spraying device to disperse the liquid adhesive into the fiber web, followed by drying, baking and other processes.
The web is bonded and reinforced. The spray-bonded non-woven fabric indicates the name of this method or product.
Twenty, printing and bonding non-woven fabric
The printing bonding method is to use the printing method to apply the liquid adhesive to the web, and then through baking and other processes to make the fiber
The net is bonded and reinforced. The nonwoven fabric of printing bonding method indicates the name of this method or product.
Twenty-one, non-woven fabrics by hot melt bonding method
The hot melt bonding method is to heat the web containing thermoplastic fibers, powder or film to make the hot melt material all or part
Melt to produce adhesive reinforcement. Hot-melt bonded nonwoven fabrics indicate the name of this method or product.
Twenty-two, hot-rolled bonding method non-woven fabric
The hot rolling bonding method is to heat and press the web containing thermoplastic fibers at the same time to make the hot melt material all or part
Melt to produce adhesive reinforcement. The nonwoven fabric of hot-rolled bonding method indicates the name of this method or product.
23. Meltblown 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 shape on the condensed screen belt or roller
It is formed into a web on the tube, and at the same time, it is bonded to form a non-woven fabric. Melt-blown nonwoven fabric means this polymer is extruded
The production method or product name of the nonwoven fabric into the cloth method.
Twenty-four, film split method nonwoven fabric
The film cracking method is to make the film form a network through mechanical action (such as needle cracking, embossing, etc.) at the stage of polymer extrusion film formation
Ultra-thin nonwoven fabric with fibrous structure or fibrillation. Film split nonwoven means that this polymer is extruded into cloth nonwoven
The production method of the cloth or the name of the product. This type of non-woven fabric is mainly used for hot melt in lamination processing or hot melt bonding
Adhesive media.
25. Durable non-woven fabric
This refers to non-woven fabrics that can be used many times or have a certain service life.
26. Use disposable non-woven fabrics
This mainly refers to non-woven fabrics for one-time use, in fact, it can sometimes be used more than once, even up to 4
5 times.
Twenty-seven, dry papermaking nonwoven fabric
In recent years, a new technology of non-woven fabrics has developed rapidly abroad. Its English name is: air-laid-pulp nonwovens. This is a paper-making raw material-wood pulp board as a raw material. The name of a production method or product that is chemically and thermally bonded into a nonwoven fabric.
