Abstract

The invention relates to an energy-increased spun-bondedfilter material containing polypropylene/polyester and a preparation method of the energy-increased spun-bonded filter material. The filter material comprises three layers of fiber meshes bonded together, wherein the fiber meshes comprise a coarse-denier fiber mesh, an intermediate-denier fiber mesh and a fine-denier fiber mesh sequentially; fibers in the fiber meshes are sheath-core composite fibers; the coarse-denier fiber mesh, the intermediate-denier fiber mesh and the fine-denier fiber mesh are spun sequentially, stacked, then bonded for reinforcement and subjected to polished roller hot rolling, corona processing of electrets and winding, and the energy-increased spun-bonded filter material containing polypropylene/polyester double components is obtained. The filter material has fluffy and soft structure and high filter efficiency while maintaining lower resistance. Besides, the preparation method is environment-friendly, simple and feasible in process and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of spun-bonded filter material and its preparation, in particular to an energy-enhancing polypropylene / polyester two-component spun-bonded filter material and a preparation method thereof. Background technique [0002] With the development of the economy, the pollution of industrialization has become more and more serious, and the air quality has dropped significantly, causing serious adverse effects on people's transportation, production and life, and physical health. Among them, particulate matter, as the main component of air pollution, absorbs a large amount of toxic and harmful substances, causing serious damage to the human respiratory system and cardiovascular system, leading to a significant increase in the incidence of bronchitis, asthma, myocardial infarction and other diseases. The most direct and effective control of air pollution in terms of personal protection and indoor purification is the use of filter...
