It is formed by directional or random arrangement of textile short fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is a new type of fiber product with soft, breathable and flat structure formed by directly using polymer chips, short fibers or filaments through various fiber web forming methods and consolidation technologies.

[0003] In some use occasions, nonwoven fabrics are required to have a hydrophilic function. At present, nonwoven fabrics with hydrophilic function are produced by setting a sprayer between the unwinding roller and the winding roller. The sprayer has multiple spray holes. When the nonwoven fabric is transmitted, the spray holes continuously spray the hydrophilic agent. The nonwoven fabric produced by spraying the hydrophilic agent with this sprayer has poor hydrophilic uniformity. This is because the uniformity of the spraying amount in each spray hole is difficult to control, resulting in uneven hydrophilic dosage in each area of ​​the nonwoven fabric surface.
