Problems solved by technology

The automotive air conditioner filter medium in the prior art generally adopts paper fiber, glass fiber or polymer fiber, wherein the paper fiber has a limited life due to the unique corrosion resistance or weather resistance of paper; glass fiber is suspected to be carcinogenic Therefore, it is not expected to be used in air filters. The polymer fibers used in mainstream automotive air conditioning filter products in the market are basically electrospun or electroblown. As described in WO03 / 080905A and WO2006 / 071980, the processes are relatively complicated , resulting in high product costs

Embodiment 1

[0037] Mix 35% by weight polyester staple fibers and 65% by weight bamboo fiber evenly, and after the mixed fibers are roughly opened and finely opened in turn, the mixed fibers are sent to a carding machine for carding , After the auxiliary installation, the speed of the acupuncture machine is 350 times / min, and the density is 4500 pieces / square meter, so that the polyester staple fiber and the bamboo fiber are evenly mixed into one. When the pre-punched fabric is sent out from the pre-punched machine, spunlace non-woven fabric is laid on the bottom, pp non-woven fabric and melt-blown non-woven fabric are laid on the top; then the compounded fabric is put into the needle punching machine at a speed of 450 times / Minute needle planting, the density is 4500 pieces / square meter; the four layers of materials can be evenly and evenly bonded together; the punctured fabric is sent to the hot roller for contact, the pressure is adjusted to 4 kg / square meter, and the temperature of the...

Abstract

The invention discloses an automotive air conditioning filtering material and a preparation method thereof. The filtering material is formed integrally from four fiber layers, i.e. a PP (polypropylene) non-woven fabric filtering layer, a polarized melt-spurt polypropylene non-woven fabric filtering layer, a bamboo fiber filtering layer and a water-spurt non-woven fabric filtering layer through tight adhering with needling. The method has a simple process and low cost; and the obtained filtering material can effectively remove harmful microorganisms, dust and volatile organic compounds in air.

Description

technical field [0001] The invention relates to a filter material for an automobile air conditioner and a preparation method thereof. Background technique [0002] With the increasing popularity of automobiles and the wide application of a large number of new decorative materials, the air pollution in the car is further aggravated, and the problem of air quality in the car has become more prominent. The air quality inside the car is closely related to the health of the human body, especially gaseous pollutants such as volatile organic compounds (TVOC) are the most serious harm to the human body. The automotive air conditioner filter medium in the prior art generally adopts paper fiber, glass fiber or polymer fiber, wherein the paper fiber has a limited life due to the unique corrosion resistance or weather resistance of paper; glass fiber is suspected to be carcinogenic Therefore, it is not expected to be used in air filters. The polymer fibers used in mainstream automotive...
