Problems solved by technology

[0003] The existing cooling design is mostly a cylindrical structure, including the outer wrapping layer and the cooling structure filled inside. The commonly used cooling structure includes multiple fiber bundles arranged side by side, or a folded structure of sheet materials. Although these cooling structures A certain cooling effect can be obtained, but the effect is not obvious. In addition, when these cooling structures are produced, due to their complex structures, the manufacturing difficulty is increased and the production cost is increased.

preparation example Construction

[0037] see figure 1 — image 3 , a kind of preparation method of embedded cooling filter double excellent composite fiber, described preparation method comprises the following steps:

[0038] PLA powder treatment: ball milling and dispersing the existing PLA powder 4 until the size of the PLA powder 4 is 50-500 mesh;

[0039] Mixing of powder and liquid: first make the base liquid 5 in a state of being stirred, then add the dispersed PLA powder 4 to the base liquid 5, and add it while stirring until all the PLA powder 4 is added to obtain a mixed solution 6, and then the primary mixed solution 6 is dispersed to obtain the secondary mixed solution 7;

[0040] Formation of composite fibers: first perform spinning operation on the above-mentioned secondary mixed liquid 7 to obtain initial fibers, the spinning operation is wet spinning or electrospinning or centrifugal spinning or combined use of electrospinning and centrifugal spinning, Then the initial fiber is passed through...

Abstract

The invention relates to a preparation method for embedded composite fibers with excellent cooling and filtering effects. The method comprises the following steps of firstly, carrying out ball-milling dispersion on existing PLA powder particles until the size of the PLA powder particles is 50-500 meshes; enabling base liquid to be in a stirred state; adding the dispersed PLA powder particles into the base liquid during stirring, and obtaining first mixed liquid until all the PLA powder particles are added; dispersing the first mixed liquid to obtain second mixed liquid; spinning the second mixed liquid to obtain initial fibers, wherein spinning is electrostatic spinning or centrifugal spinning or both electrostatic spinning and centrifugal spinning; and enabling the initial fibers to pass through a thermal drying box to be dried and set, so that the embedded composite fibers with excellent cooling and filtering effects are obtained. According to the design, the preparation difficulty is relatively low, and a product is relatively strong in cooling effect, relatively good in filtering effect and relatively high in environment friendliness.

Description

technical field [0001] The invention relates to the preparation of a composite fiber, which belongs to the field of post-treatment of flue gas, in particular to a preparation method and product of an embedded cooling and filtering dual-excellence composite fiber. Background technique [0002] In the existing tobacco products, whether it is a cigarette or a heat-not-burn tobacco, it is necessary to set a cooling design inside the structure. When it is applied, the smoke generated by the cooling design is used to cool down the temperature, so as to avoid the excessive temperature. The smoke burns the user's mouth, and secondly, it can reduce the production of harmful substances, making it healthier and more environmentally friendly. [0003] The existing cooling design is mostly a cylindrical structure, including the outer wrapping layer and the cooling structure filled inside. The commonly used cooling structure includes multiple fiber bundles arranged side by side, or a fold...
