Overview Of Fiber Mesh Non-woven Fabrics

Jul 14, 2021

As the name implies, "optical fiber laying" is to make optical fibers into meshes. Commonly used methods are dry, wet, spinning, meltblown and so on.

Dry laying and wet laying are more suitable for short fiber laying. It is usually necessary to pre-treat the fiber raw materials, such as tearing large fiber clusters and fiber blocks into small pieces to loosen them and remove impurities. The various fiber components are uniformly mixed and prepared before forming the fiber web. The dry method usually involves carding and laying pre-treated fibers into a web of a certain thickness. Wet-laid is to disperse short fibers in water containing chemical additives to form a suspension, and then filter the water. The fibers deposited on the filter will form a non-woven fiber web.

Both non-woven spinning and meltblown webs are spinning methods that use chemical fibers, and the fibers are laid directly during the spinning and forming process. The spinning solution or melt is sprayed from the spinneret after cooling and stretching to form filaments with a certain fineness, and a fiber web is formed on the receiving device. The melt-blown fiber web uses high-speed hot air to stretch the thin stream ejected from the spinneret to form ultra-fine fibers, and then the ultra-fine fibers are collected on a receiving device to form a fiber web. The small diameter of the melt-blown fibers is helpful to improve the filtration efficiency.
