Usage:
Spunbonds are used mainly for hygiene products such as baby and adult diapers, feminine care, and medical products such as protective apparel. Spunbonds also are used more and more in technical applications. These are used mainly for construction, coating substrates, agriculture, battery separators or even disk covers.
介紹：
紡粘無紡布：是在聚合物已被擠出、拉伸而形成連續長絲后，長絲鋪設成網，纖網再經過自身粘合、熱粘合、化學粘合或機械加固方法，使纖網變成無紡布。
特點
高強度、耐高溫性能好（可在150℃環境中長期使用）、耐老化、抗紫外線、延伸率高、穩定性和透氣性好、耐腐蝕、隔音、防蛀、無毒。
Description:
Spunbonding Process
It is similar to filament yarn production. From the chips storage, the polymer is vacuum-fed to a dosing station on top of the extruder. Inside the extruder, it becomes melted and homogenized. Passing a filter system and a spin pump, the melt is fed into the spin beam or spinnerets, which form a curtain of filaments. The filaments are cooled by means of a stream of air in a blowing area, drawn by aerodynamic forces and then transported to the downstream discharge channel. For nonwovens, instead of a further stretching process for filament yarns, the filaments are swirled around and then deposited on the wire mesh belt as a random nonwoven. This web is transferred to a bonding calender that uses heat and pressure to set such physical properties as tensile strength and elongation of the final product. After cooling, the material can be wound.

Finishing For More Products
Spunbonds are very versatile products. They can be printed, laminated or electrostatically charged; and have improved hydrophilic properties through the application of tensides. By using additives or pigment pastes, spunbonds can be dyed in many different shades, have flame-retardant or antistatic properties, and be used for increased ultraviolet and gamma ray protection.
Physical Properties
Endless filaments in combination with a uniform discharge guarantee low weight while retaining strength. Spunbonds have a quite high air permeability, use no chemicals, are thermobonded, and have a very good bidirectional machine direction/cross direction, and wear properties. Compared to only a few years ago, modern spunbonds are soft and comfortable, and the average weight today is 10 to 150 grams per square meter.
