Classification and characterization of non-woven fabrics

　　Nonwovens, also known as non-woven fabrics, are constructed from oriented or random fibers. It is called cloth because it has the appearance and some properties of the cloth. There are many types of non-woven products, and different non-woven fabrics have different characteristics. Let's look at the classification characteristics of non-woven fabrics together with Xiaobian.

　　1. Wet-laid non-woven fabric: the fiber raw material placed in the water medium is opened into a single fiber, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is in a wet state. Reinforce the cloth into a cloth.

　　2. Non-woven fabric: It is a kind of dry non-woven fabric. The stitching method is to use warp knitting coil structure for web, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.) or Their combination is reinforced to form a nonwoven fabric.

　　3. Spunlaced non-woven fabric: The high-pressure fine water flow is sprayed onto one or more layers of the fiber web to entangle the fibers with each other, so that the fiber web can be reinforced and has a certain strength.

　　4. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric is a puncture effect of a lancet, and the fluffy fiber web is reinforced into a cloth.

　　5. Pulp air-laid non-woven fabric: It can also be called non-dust paper, dry papermaking non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses a gas flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.

　　6. Meltblown non-woven fabric: the process: polymer feeding - melt extrusion - fiber formation - fiber cooling - meshing - - reinforcement into cloth.

　　7. Heat-bonded non-woven fabric: refers to the addition of fibrous or powdered hot-melt adhesive reinforcement material to the fiber web, and the fiber web is further fused and cooled to form a cloth.

　　8. Spunbond nonwoven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. The method is to make the web into a non-woven fabric.

　　9.pp spunbond non-woven fabric: used in packaging shopping bags, CD inner pages, travel accessories, disposable medical supplies, automotive supplies, daily necessities, agricultural supplies, etc. pp spunbonded non-woven fabrics are an alternative to traditional fabrics and A revolutionary product in paper.
