Nonwoven Fabric The exact name of non-woven fabrics should be nonwoven, or not woven. China National Standards GB/T5709-1997 the definition of nonwoven fabrics for textiles The terminology of Nonwovens is: a directed or randomly arranged fiber, by rubbing, holding, or bonding, or the combination of these methods, made of sheet, fiber mesh or mat, excluding paper, woven fabrics, knitted fabrics, tufted fabrics, and wet-shrink carpet products. Because it is a kind of fabrics that do not need to be spun yarn, it is only the textile short fiber or filament to be directed or randomly arranged, forming a fiber network structure, and then using mechanical, thermal adhesive or chemical methods to reinforce.
Nonwoven Fabric Classification of non-woven fabrics
Nonwovens breakthrough The traditional textile principle, and has a short process, rapid production speed, high yield, low cost, wide use, many sources of raw materials, is a new generation of environmentally friendly materials, with waterproof, breathable, flexible, non-combustion, non-toxic non-irritating, colorful and other characteristics.
Non-woven fabrics are mainly polypropylene fiber (PP), polyester (PET). In addition, Nylon (PA), viscose fiber, acrylic, ethyl LUN (HDPE), Shang (PVC).
Nonwoven Fabric According to the application requirements: non-woven fabrics are divided into disposable applications and durable two categories.
Nonwoven Fabric According to the production process is divided into:
1 Nonwoven Fabric spunlace nonwoven: The spunlace process is to spray high-pressure micro-flow into one layer or multi-layer fiber online, so that the fibers intertwine together, so that the fiber network can be strengthened and have a certain strength.
2 Nonwoven Fabric Thermal Non-woven fabrics: Hot bonded non-woven fabrics are in the fiber mesh to add fibrous or powdered hot-melt bonding reinforcement materials, fiber network after heating and melting cooling to strengthen into cloth.
3 Nonwoven Fabric pulp airflow into net non-woven fabrics: air-mesh non-woven fabrics can be called dust-free paper, dry paper non-woven fabrics. It is the use of air-mesh technology to open the wood pulp fiberboard into a single fiber state, and then use the Airflow method to make fiber agglutination in the net curtain, fiber mesh reinforcement into cloth.
4 Nonwoven Fabric Wet Non-woven fabrics: wet non-woven fabric is placed in the water medium fiber raw materials into a single fiber, at the same time make the mixture of different fiber raw materials, made of fiber suspension pulp, suspended slurry transported to the network mechanism, fibers in the wet state of the mesh reinforcement into cloth.
5 Nonwoven Fabric spunbonded Non-woven fabrics: spunbonded nonwoven fabric is in the polymer has been extruded, stretched and formed a continuous filament after the laying of the wire mesh, fiber network after its own bonding, hot bonding, chemical bonding or mechanical reinforcement methods, so that the network into non-woven fabrics.
6 Nonwoven Fabric Melt Spray Non-woven: Melt Spray Nonwoven fabric process: Polymer Feeding---melt extrusion---fiber formation---fiber cooling---mesh---reinforcement into cloth.
7 Nonwoven Fabric Acupuncture Non-woven: acupuncture Non-woven cloth is a dry non-woven cloth, needle-punched nonwoven cloth is the use of needle puncture effect, the fluffy fiber mesh reinforcement into cloth.
8 Nonwoven Fabric Seam non-woven fabrics: sewing non-woven cloth is a dry non-woven fabrics, sewing method is the use of warp-knitted coil structure of fiber mesh, yarn layer, non-woven materials (such as plastic sheeting, thin metal foil, etc.) or their combination of reinforcement to make non-woven fabrics.
9 Nonwoven Fabric hydrophilic Non-woven fabrics: mainly used in the production of medical materials to achieve better feel and not scratch the skin. Like sanitary napkins, sanitary pads are the hydrophilic non-woven fabrics with the function of water.
