Problems solved by technology

However, perforated non-woven fabrics are generally produced offline. After the non-woven fabric is rolled, it is unrolled, punched, and wound into a roll. The process is more complicated, the equipment is more complicated, and it is a waste of labor.

Embodiment 1

[0024] The preparation of nonwoven materials by spunbond method includes four main processes of spinning, stretching, web forming and consolidation.

[0025] In this example, through the technical transformation of the mesh belt in the netting process, such as Image 6 and Figure 7 Shown, make mesh belt 4 have bump structure 16, and this mesh belt columnar bump can be conical or cylindrical 11, can be triangular columnar 12, also can be square columnar 13, pentagonal columnar 14, hexagonal columnar 15, and all regular or irregular columns, forming such figure 1 A non-woven fabric with circular holes 1 as shown, or as figure 2 A non-woven fabric with triangular holes 2 as shown, or as image 3 The non-woven fabric 3 with hexagonal holes is shown, or a non-woven fabric with all regular or irregular holes can be formed. process such as Figure 4 As shown, the mesh belt 4 has a uniformly distributed columnar structure, and the spunbond fibers are spun and laid from the spun...

Embodiment 2

[0027] In this example, also through the technical transformation of the mesh belt, such as Image 6 and Figure 7 Shown, make mesh belt 4 have bump structure 16, and this mesh belt columnar bump can be conical or cylindrical 11, can be triangular columnar 12, also can be square columnar 13, pentagonal columnar 14, hexagonal columnar 15, and all regular or irregular columns, forming such figure 1 A non-woven fabric with circular holes 1 as shown, or as figure 2 The shown nonwoven fabric 2 with triangular hole structure, or as image 3 The non-woven fabric 3 with a hexagonal pore-like structure may be formed into a non-woven fabric with all regular or irregular holes. process such as Figure 5 As shown, the mesh belt 4 has a uniformly distributed columnar structure, and the spunbonded fibers are spun and laid on the mesh belt 4 with a columnar structure from the spunbond equipment 8 and the spunbond equipment 9 respectively, forming a two-layer porous structure. The fiber...

Abstract

The invention discloses a punched spunbonded nonwoven material and a manufacturing method thereof. The material forms an obvious and regular uniform porous structure fiber web in the process of forming fibers into a web; and in the manufacturing method, the web tape part of the conventional nonwoven equipment is reformed, so that the surface of the web tape has a salient point structure. The spunbonded nonwoven material prepared by the method ensures that the fibers cannot be damaged, the integrity of the fibers is kept, the physical properties such as toughness and the like cannot be lost, and the flexibility of the material is kept; meanwhile, because the web tape forming part is reformed and other equipment is not needed to be changed, the method cannot be conflicted with the common production process of spinning to form webs and is compatible with the conventional equipment and process, saves procedures and equipment, is easy to implement and has lower production cost.

Description

technical field [0001] The invention relates to a method for manufacturing a spun-bonded nonwoven material, in particular to a method for manufacturing a perforated spun-bonded nonwoven material. Background technique [0002] For products such as disposable personal care sanitary napkins and diapers, the permeability is a very important indicator. Although many sanitary napkins and diapers on the market emphasize the instant suction function, they do not actually achieve the instant suction effect. Some The product sacrifices other excellent properties in order to achieve the instant suction effect. The main reason for this is the selected materials. These materials are basically soft hot air materials or dry PE perforated films. They are used to produce hot air materials. The raw material is basically polyethylene or polypropylene, or polyethylene / polypropylene bicomponent fiber, which has poor hydrophilicity and water absorption performance, and the bonding point is bonded...
