Problems solved by technology

Among them, the mechanical method mainly adopts the acupuncture method, and the functional filter material generally undergoes a post-finishing process to make the product have corresponding functions. In the existing manufacturing method of the functional filter material, the impregnation process is required, and the impregnation process will increase production. Process costs, especially harmful substances will be produced, causing harm to the environment, and the process is complex, material costs, labor costs, and energy consumption remain high

Embodiment 1

[0031] A method for manufacturing a nonwoven dust filter material, comprising the steps of:

[0032] A. The polyester staple fibers with a diameter of 2.5mm and a length of 51mm are sequentially pre-opened, finely opened, and cotton box beating processes to form opened cotton;

[0033] B. Use the mist spray humidification device to spray and humidify the opened cotton made in step A, and then use the carding machine to card, so that the opened cotton moves forward in parallel and evenly and falls on the laying net Machine surface, carry out laying net, prepuncture to form the fluffy and uniform non-woven floc layer 1, and described prepuncture needle depth is 11mm; In the humidification liquid that described mist spray humidification device uses, mix elemental surfactant, The blending ratio of elemental surfactant and water is 1.8:100, spray 15g of humidifying liquid per square meter of non-woven dust filter material; elemental surfactant contains fluorine element and hydrophi...

Abstract

The invention discloses a manufacturing method of a non-woven dedusting filter material, which has the advantages of enabling the filter material to be higher in intensity and lower in running resistance. The method comprises the following steps: A, polyester staple fiber is enabled to form opened cotton through the procedures of pre-opening, fine-opening, and cotton tank scutching; B, vaporific spraying humidification finishing is performed, by using a vaporific spraying humidification device, on the opened cotton made in the step A, then a carding machine is used for carding, the opened cotton is enabled to move parallelly and evenly and falls onto the surface of a lapping machine for lapping and pre-stabbing so as to form a fluffy and even nonwoven wadding making layer; C, after mixing bright polyester fiber and polyester staple fiber according to the weight ratio of 3 to 1, a mixed fibrous layer is formed through procedures of pre-opening, fine opening, cotton box scutching, carding, lapping and pre-stabbing in sequence.

Description

technical field [0001] The invention relates to a method for manufacturing textiles, in particular to a method for manufacturing nonwoven dust filter material. Background technique [0002] At present, dust filter materials are generally woven in a non-woven manner, that is, short fibers or filaments are oriented or randomly arranged to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Among them, the mechanical method mainly adopts the acupuncture method. The functional filter material generally undergoes a post-finishing process to make the product have corresponding functions. In the existing manufacturing method of the functional filter material, the impregnation process is required, and the impregnation process will increase production. Process costs, especially harmful substances will be produced, causing harm to the environment, and the process is complex, material costs, labor costs, and energy consumption remain high...
