[0029] A method for preparing a high-elastic antibacterial nonwoven fabric of the above-mentioned film-bonded honeycomb structure, the method comprises the steps of:
[0030] (1) Preparation before web formation: first mix and open various fiber raw materials required for preparing the upper layer fiber web 3 , the elastic fiber web 4 and the lower layer fiber web 5 . The non-woven mixed opening equipment runs at a high speed. Since the raw materials are all chemical fibers, the hygroscopicity is poorer than natural ones, and static electricity is easily generated during the mixed opening process. Adding an oil agent during the opening process can prevent static electricity. affect the quality. The preparation material of the upper layer fiber web 3 and the lower layer fiber web 5 is a mixture of low-melting point polyester staple fiber and three-dimensional crimped hollow polyester staple fiber. In the upper layer fiber web 3 and the lower layer fiber web 5, the weight percen...
Embodiment 1
[0040] A film bonded honeycomb structure high elastic antibacterial nonwoven fabric with a thickness of 200 mm and a preparation method thereof.
[0041] See figure 1 , figure 2 , a high-elastic antibacterial nonwoven fabric with a film-bonded honeycomb structure, comprising a plurality of composite fiber webs 1 stacked in sequence, the interior of the composite fiber web 1 is sprayed with an antibacterial agent 6, and the composite fiber webs 1 are connected end to end in sequence, arranged The way is a reciprocating Z-shape, the angle between adjacent composite fiber webs 1 is 0 degree or close to 0 degree, and a hot-melt film 2 is sandwiched between adjacent composite fiber webs 1 . The structure of the hot-melt film 2 is net shape, the melting point is less than or equal to 110°, and the thickness is less than 0.05mm.
[0042] The composite fiber web 1 is a layered fiber web, which includes an upper layer fiber web 3 , an elastic fiber web 4 , and a lower layer fiber we...
