Classification and application of non-woven fabrics
Nonwoven fabric scientific name: Nonwovens, also known as Nonwovens, nonwoven fabrics, nonwoven fabrics, nonwoven fabrics.Nonwoven technology is a kind of material processing technology which originated from textile but surpasses textile.
Non-woven fabrics are classified as follows:
一. classification according to production process:
1. Spiny non-woven fabric:
The high pressure water jet to a layer or multi-layer fiber network, so that the fiber interlock together, so that the fiber network can be strengthened and have a certain strength.
2. Heat-bonded non-woven fabric:
Refers to the addition of fiber mesh fiber or powder hot fusion bonding reinforcement materials, fiber mesh after heating and cooling reinforcement into cloth.
3, pulp into a net of non-woven cloth:
Also known as dust - free paper, dry - process paper - making non - woven.It is the use of air mesh technology to open the wood pulp fiberboard loose into a single fiber state, and then use the air flow method to make the fiber agglutination in the mesh curtain, fiber mesh reinforcement into cloth.
4. Wet non-woven:
The fiber material placed in the water medium is loosened into single fiber, and different fiber materials are mixed at the same time to make fiber suspension slurry. The suspension slurry is transported to the netting mechanism, and the fiber is netted and reinforced into cloth under the wet state.
5. Spun-bonded non-woven fabric:
After the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a network, and the fiber network is bonded by its own adhesion, thermal adhesion, chemical adhesion or mechanical reinforcement, so that the fiber network becomes non-woven.
6. Melt-sprayed non-woven fabric:
Its process: polymer feeding → melt extrusion → fiber formation → fiber cooling → mesh → reinforcement into cloth.
7. Acupuncture non-woven fabric:
One of the dry non-woven fabrics, needling non-woven fabric is to use the puncture function of the needle, the fluffy fiber network into the reinforcement of the cloth.
8. Sewn non-woven:
A type of dry nonwoven fabric in which a warp knitting coil structure is used to reinforce a mesh, yarn layer, nontextile material (e.g. plastic sheet, plastic foil, etc.) or a combination of them to produce nonwoven fabric.
二. Classification by use:
1. Non-woven fabrics for medical and sanitary use:
Operating clothes, protective clothing, disinfectant bag cloth, mask, diaper, civilian dishcloth, wiping cloth, wet face towel, magic towel, soft towel roll, beauty products, sanitary napkin, sanitary pad and disposable sanitary cloth, etc.
2. Non-woven fabrics for home decoration:
Wall cloth, table cloth, bed sheet, bedspread, etc.
3. Non-woven clothing:
Lining, adhesive lining, flocs, shaping cotton, all kinds of synthetic leather cloth;
4. Industrial non-woven:
Filtration materials, insulation materials, cement packaging bags, geotextile, covering cloth, etc.
5. Non-woven fabrics for agricultural use:
Crop protection cloth, seedling cloth, irrigation cloth, heat preservation curtain, etc.
6. Other non-woven fabrics:
Space cotton, insulation materials, linoleum, smoke filter, tea bags, etc.
