Abstract

The invention discloses a novel hot-rolled air filtering aggregate and a manufacturing method thereof. The novel hot-rolled air filtering aggregate is prepared from, by mass, 60- 80 percent of 15D polyester staple fiber, and 20- 40 percent of 7D modified polyester staple fiber. The usage temperature of the 15D polyester staple fiber is 120- 150 DEG C, the 7D modified polyester staple fiber has a skin-core structure, and a skin layer and a core layer account for 50 percent respectively; the usage temperature of the skin layer is 110-140 DEG C, and the usage temperature of the core layer is 120-150 DEG C; two fibers are processed by using a fiber mixing process, a mechanical carding and netting process and a heat setting and heat strengthening process to form a fiber net surface with certainstiffness. The novel hot-rolled air filtering aggregate and the manufacturing method thereof has the advantages that thermal bonding between fibers is directly utilized for curing and bonding, the rigidity of a product is not affected, fiber characteristics are kept intact, contact surface area between turbid gas and the fibers is increased, a good low pressure difference is maintained, and the service life of a filter is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of filter materials, in particular to a new type of hot-rolled air filter aggregate that uses glue-free bonding technology, which can reduce production environmental protection pressure, improve production efficiency, is not easy to deform, and is flexible in filtering methods, and can increase the service life of filter elements And production method. Background technique [0002] Filter material is an important base material for trapping particulate matter in gas and liquid. It is an important part of filtration equipment, which separates particulate matter and is an important part of keeping the atmosphere and liquid environment clean. For gas filtration, fluffy fiber flakes are used as filter substrates, which are often used in air conditioning and ventilation systems. The preparation of fluffy flakes often uses the form of sprayed cotton to make the voids of the flakes reach more than 80%. The filt...
