Example Embodiment

[0058] Example 1

[0059] The design weight is 210g / m 2 , And is a "sandwich layer" structure of bamboo fiber automotive air-conditioning filter element, the three-layer thin needle felt is 70g / m 2 , The mass mixing ratio of bamboo fiber / PP fiber is 50 / 50, 70 / 30 and 50 / 50 respectively. The raw bamboo fibers and PP fibers of each thin needled felt are fed according to the set mass percentages, and then coarsely opened. After mixing and fine opening, the mixed fiber mass is 4% and the oil agent with a mass concentration of 2% is sprayed, and Placed in a closed environment for pretreatment for 8 hours; the pretreated mixed fiber is carded and laid into a net, the needle punch speed is 300-400 times / min, and the needle density is 2000 pieces / m 2 , The temperature of the upper and lower rolls of the hot rolling mill is 170℃, the gauge is 0.5mm, and the grammage is 70g / m. 2 The mixing ratio is 50 / 50, 70 / 30 and 50 / 50 thin bamboo fiber filter layer. The three-layer thin bamboo fiber filt...

[0064] Example 2: Other preparation processes are the same as Example 1, and the weight is 210g / m 2 The original bamboo fiber filter element for automobile air-conditioning has a weight of 105g / m 2 The two layers of thin needle-punched felt are composited, and the mass mixing ratio of bamboo fiber / PP fiber is 50 / 50 and 70 / 30 respectively.

[0065] The finished product is tested, the filtration efficiency is ≥62%, and the air permeability is 3571.8L / m 2 ·S.

Example Embodiment

[0066] Example 3: Other preparation processes are the same as Example 1, and the weight is 300g / m 2 The original bamboo fiber filter element of automobile air conditioner has a weight of 150g / m 2 The two layers of thin needle-punched felt are composited, and the mass mixing ratio of bamboo fiber / PP fiber is 50 / 50 and 70 / 30 respectively.

[0067] The finished product is tested, the filtration efficiency is ≥74%, and the air permeability is 2589.6L / m 2 ·S.

[0068] The structure design of the bamboo raw fiber automobile air conditioning filter element of the present invention selects medium thick bamboo fiber with a fineness of 3-5 tex and a length of 30-35 mm, and a PP fiber with a fineness of 3-7 denier and a length of 30-40 mm. As a filter material, it reduces the requirements for bamboo fiber and PP fiber in the production and use, and reduces the cost of bamboo fiber filter material. Different quality mixed ratio bamboo / PP thin needle felt made of 0.1-0.2g / m 3 Lay the composite ...

Abstract

The invention provides a raw bamboo fiber automobile air conditioner filter element and a preparation method thereof. The filter element is composed of at least two layers of raw bamboo fiber and polypropylene fiber thin needled mats through needling and hot-rolling adhesion; the mass mixing ratios of the raw bamboo fiber to the polypropylene fiber in each thin needled mat are different; the fineness of the raw bamboo fiber is 3-5tex, and the length is 30-35mm; the fineness of the polypropylene fiber is 3-7 deniers, and the length is 30-40mm; and the volume density of each thin needled mat is 0.1-0.2g/cm<3>, and the gram weight is 70-150g/m<2>. Through the invention, the uniform state of transfer and distribution of each component fiber in the thin needled mat can be improved, the independent filtering performance of each thin needled mat is guaranteed, the production cost can be lowered, and the air permeability and filtering efficiency of the filter element are improved.

Description

【Technical field】 [0001] The invention relates to a bamboo fiber automobile air-conditioning filter element and a preparation method thereof. 【Background technique】 [0002] Bamboo fiber is rich in resources and has excellent air permeability, adsorption, antibacterial and other properties, which can effectively improve the filterability of filter materials and the adsorption and inhibition of harmful microorganisms and gases. At present, there is little research on bamboo fiber in the field of filtration, and its development and application in filter materials are greatly restricted. [0003] The invention of existing bamboo fiber filter material adopts acupuncture process to form PP non-woven fabric, polarized melt-blown polypropylene non-woven fabric, composite bamboo fiber filter layer and spunlace non-woven fabric at one time. [0004] For example: the application number is 201110036652.7, and the application date is a Chinese patent on January 30, 2011, which disclose...
