Embodiment 1
[0042] A preparation method of a three-dimensional nonwoven material with controlled fragrance release, comprising the following steps:
[0043] (1) Preparation of fiber web messy carding and forming. The corresponding hydrophobic hollow polyester fibers and hydrophobic ES (PE / PET) fibers were weighed in a mass ratio of 4:6. The two kinds of fiber raw materials are opened, mixed, antistatic treatment and carded to obtain a messy fiber web with a pore size of 100-150 μm. The carding adopts a single-cylinder double-doffer carding machine, and the cylinder speed is 303r / min and the doffer speed is 7.54. r / min, the rotation speed of the feeding roller is 0.76r / min, the rotation speed of the random roller is 6.03r / min, and the rotation speed of the winding roller is 10.73r / min.
[0044] (2) Wet homogeneous and aromatizing composite of disordered fiber network and aromatic micro-nanocapsules. At room temperature, the aromatic micro-nanocapsule emulsion (mL): deionized water (mL) =...

[0050] (2) Wet homogeneous and aromatizing composite of disordered fiber network and aromatic micro-nanocapsules. At room temperature, use aromatic micro-nanocapsule emulsion (mL): deionized water (mL) =...
Embodiment 3
[0054] A preparation method of a three-dimensional nonwoven material with controlled fragrance release, comprising the following steps:
[0055] (1) Preparation of fiber web messy carding and forming. The corresponding hydrophobic hollow polyester fibers and hydrophobic ES bicomponent (PE / PET) fibers were weighed in a mass ratio of 4:6. The two kinds of fiber raw materials are opened, mixed, antistatic treatment and carded to obtain a messy fiber web with a pore size of 100-150 μm. The carding adopts a single-cylinder double-doffer carding machine, and the cylinder speed is 303r / min and the doffer speed is 7.54. r / min, the rotation speed of the feeding roller is 0.76r / min, the rotation speed of the random roller is 6.03r / min, and the rotation speed of the winding roller is 10.73r / min.
[0056] (2) Wet homogeneous and aromatizing composite of disordered fiber network and aromatic micro-nanocapsules. At room temperature, the aromatic micro-nanocapsule emulsion (mL): deionized ...
