Nonwoven fabric is one of dry non-woven fabrics, also known as needle felt. Made of polyester and polypropylene raw materials, it is processed by appropriate hot rolling after repeated acupuncture. The short fibers are opened, combed, and laid into a fiber web, and then the fiber web is reinforced by a needle to form a cloth, and the needle has a hook. The fiber web is repeatedly pierced, and the hook tape is reinforced to form a needle-punched nonwoven fabric. The non-woven fabric has no warp and weft, and the fibers are disordered, and the warp and weft performance is not much different.
Typical products: non-woven fabrics for greenhouse insulation, road maintenance felts, synthetic leather base fabrics, needle-punched geotextiles, etc.
Below, Lai Chi Xiaobian introduces some related terms of non-woven fabrics to make you look more professional.
Dry non-woven fabric: Any non-woven process in which the fibers are formed into a web by mechanical, airflow, static electricity or a combination thereof in a dry state, and then reinforced by mechanical, chemical or thermal methods, collectively referred to as short-fiber dry method. Non-woven.
Wet non-woven fabric: A non-woven fabric process or product that is woven in a wet state suspended in water by a papermaking method and then reinforced by mechanical, chemical or thermal means.
Polymer extruded non-woven fabric: a non-woven fabric process or product of a network structure formed by extrusion processing of a polymer material.
Netting: It is the stage of forming the fiber web. There are currently two kinds of mechanical forming and air forming.
Mechanical web forming: It is a traditional carding machine (roller type, cover type) or non-woven special carding machine to form a fiber web, and then the web is paralleled or cross-folded and laid, and then processed.
Reinforcement: It is an important process for the fiber mesh to have a certain strength and can form a nonwoven fabric structure. Currently, there are three types of mechanical, chemical and thermal reinforcement.
Mechanical reinforcement: The fibers in the web are mechanically entangled or reinforced with coiled fiber bundles or yarns.
Chemical reinforcement: Also known as chemical bonding, chemical materials such as adhesives or solvents are used to reinforce the fibers in the web due to adhesion.
Thermal Reinforcement: A method of reinforcing a web by the hot melt adhesion characteristics of thermoplastic materials (fibers, powders, films, etc.) in the web.
Durable nonwoven fabric: Also known as a durable nonwoven fabric, a nonwoven fabric having a certain life can be used multiple times.
Disposable non-woven fabric: mainly refers to disposable non-woven fabric, can also be used more than once, or even four to five times.
