First embodiment
Shown in referring to Fig.1, the present invention provides a kind of melt-blown combined embossing non-woven cloths, including stack gradually from bottom to up
Fiber bottom 1, nano-spray layer 2 and the fibre cover 3 of setting, fiber bottom 1, nano-spray layer 2 and fibre cover 3 are logical
It is successively compound to cross hot rolling, nano-spray layer 2 is made of melt-blown nano short fiber, and fiber bottom 1 and fibre cover 3 are by spunbond
Long fibre is made.
The lower surface of fiber bottom 1 and the upper surface of fibre cover 3 are meltblown respectively lower corrugated meltblown layer 5 and upper embossing
Meltblown layer 4.Upper embossing meltblown layer 4 and lower corrugated meltblown layer 5 are made of chemical synthetic fiber, and chemical synthetic fiber is by water solubility
Macromolecule and/or oil-soluble macromolecule are prepared.When chemical synthetic fiber is made of oil-soluble macromolecule, due to oil-soluble height
Molecule has the hydrophobic grouping of a large amount of long-chains, so that meltblown layer be made to have very strong oil absorption, therefore can be applied to oil absorption material
In.When chemical synthetic fiber is made of a large amount of water soluble polymers, due to water soluble polymer have multiple hydrophilic radicals as-
OH、-COOH、-SO4Group so that meltblown layer be made to have stronger water imbibition, therefore can be used in cloth for wiping or dusting material.When chemistry closes
Include simultaneously water soluble polymer and oil-soluble macromolecule at fiber, enables to the melt-blown combined embossing being prepared non-woven
Cloth has both water-soluble and two kinds of physicochemical properties of oil-soluble, and the scope of application is wider.
Further, water soluble polymer includes that water-soluble macromolecule, chemically modified natural polymers and synthesis are poly-
Close object.The hydrophilic radical on water soluble polymer surface further promotes embossing meltblown layer 4 and fiber bottom 1 and fibre cover 3
Bonding.
