Embodiment 1

[0017] The existing two-component sea-island fibers include water-soluble copolyester / polyester, water-soluble copolyester / nylon 6; fabrics include short-fiber needle-punched and spunlace nonwovens, long-fiber organic fabrics, knitted fabrics, etc. In this example, water-soluble copolyester / polyester two-component sea-island fiber non-woven fabric raw material is used, and a certain amount of two-component sea-island fiber non-woven fabric raw material is placed in a wide mouth, equipped with a heating device, an oscillating device and a sealing In the container of the cover, a certain amount of water emulsion is pre-filled in the container. In the water emulsion, the content of o-chlorophenol is 2%, the content of dodecyl benzyl dimethyl ammonium chloride is 5%, and the sea-island fiber The bath ratio of the fabric to the water emulsion is 1:5, and it is treated under shaking and room temperature for 10 minutes. The emulsified two-component sea-island fiber fabric is taken out...

Embodiment 2

[0020] A certain amount of two-component sea-island fiber fabric raw material is placed in a container with a wide mouth, a heating device, an oscillating device and a sealed cover, and a certain amount of water emulsion is pre-injected in the container, and the content of o-chlorophenol in the water emulsion is 2% ( V / V), the content of sodium dodecylbenzenesulfonate is 6% (V / V), the bath ratio of sea-island fiber fabric and water emulsion is 1:15, and it is treated for 40 minutes under the action of oscillation and at room temperature, and after emulsification treatment The two-component sea-island fiber fabric is obtained as a filter material after vibration cleaning with pure water, tenter drying and hot rolling. Its scanning electron microscope picture see figure 2 , see Table 1 and Table 2 for performance tests.

Embodiment 3

[0022] A certain amount of two-component sea-island fiber fabric raw material is placed in a container with a wide mouth, a heating device, an oscillating device and a sealed cover, and a certain amount of water emulsion is pre-injected in the container, and the content of o-chlorophenol in the water emulsion is 2% ( V / V), sodium dodecylsulfonate 3% and Pingjia-10 are 2% (V / V), the bath ratio of sea-island fiber fabric and water emulsion is 1:25, and it is processed under the action of mechanical vibration and room temperature After 20 minutes, the emulsified two-component sea-island fiber fabric was taken out, and the filter material was obtained after oscillating cleaning with pure water, tenter drying and hot rolling. Its scanning electron microscope picture see image 3 , see Table 1 and Table 2 for performance tests.

Abstract

The invention discloses a filtering material and a preparation method thereof. The preparation method comprises the following steps of: placing a double-component island fiber into emulsion formed by mixing o-chlorophenol, a surfactant and water; treating under an oscillation condition; washing by pure water; and after carrying out tentering, drying and hot-rolling treatment to obtain the filtering material. An emulsion treating technology is used for completely splitting the island fiber and the specific surface area is enlarged; and an obtained superfine fiber textile has excellent adsorption and separation function, and filtering effect. Compared with a melt-blown non-woven fabric, the island double-component fiber has the advantages of multiple varieties of fibers, large output, developed production process, great brute force and the like; and the filtering material can be applied to an ultra-cleaning filtering and cleaning field and has a popularization and application prospect.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a technology for applying ultrafine fibers obtained by splitting two-component sea-island fibers to air filter materials, and belongs to the technical field of polymer materials. Background technique [0002] The island-in-the-sea composite fiber spinning technology researched and developed by Japan in the early 1970s has matured and become the basic process for producing ultrafine fibers after decades of development. Microfiber is a fiber with a diameter of about 0.1 denier. Microfiber has a large specific surface area, and its fabric has good bulkiness and warmth retention. Fibers with large specific surface area and large surface energy have a high probability of contact with dust or oil, and can capture and fix fine dust like a magnet, so it has a strong cleaning function. Microfiber fabrics (including woven fabrics and non-woven fabrics) have super ...
