Embodiment 1

[0026] The preparation method of the cotton fiber filter material comprises opening, glue spraying, drying, edge trimming and rolling in sequence in the process steps; an air-laid step is included between opening and glue spraying, wherein the process conditions in each process step as follows:

[0027] A. Opening: The cotton-type short fibers with a fiber length of 10mm and a cotton content of more than 90% are opened for the first time through the opener by artificial dispersion method to form loose fibers, which are sent into the cotton box through the blower. Utilize the volumetric method to carry out the balance uniformity for the first time, forming a thickness of 100mm loose fiber layer; the loose fiber layer prepared in the first opening is sent into the opener through the quantitative feeding roller for the second opening, and the Cotton fibers are dispersed into basic single fibers, which are sent to the next cotton box by a blower, and the volumetric method is used ...

Embodiment 2

[0038] The preparation method of the cotton fiber filter material comprises opening, glue spraying, drying, trimming and rolling in sequence in the process steps; it is characterized in that an air-laid step is included between the opening and glue spraying, wherein each process step The process conditions are as follows:

[0039] A. Opening: The cotton-type short fibers with a fiber length of 8mm and a cotton content of more than 90% are opened for the first time through an opener by manual dispersion to form loose fibers, which are sent into the cotton box by a blower. Utilize the volumetric method to carry out the balance uniformity for the first time, forming a thickness of 100mm loose fiber layer; the loose fiber layer prepared in the first opening is sent into the opener through the quantitative feeding roller for the second opening, and the Cotton fibers are dispersed into basic single fibers, which are sent to the next cotton box by a blower, and the volumetric method ...

Embodiment 3

[0050] The preparation method of the cotton fiber filter material comprises opening, glue spraying, drying, trimming and rolling in sequence in the process steps; it is characterized in that an air-laid step is included between the opening and glue spraying, wherein each process step The process conditions are as follows:

[0051]A. Opening: The cotton-type short fibers with a fiber length of 5mm and a cotton content of more than 90% are opened for the first time through an opener by manual dispersion to form loose fibers, which are sent into the cotton box by a blower. Utilize the volume method to carry out the balance uniformity for the first time, forming a thickness of 100mm loose fiber layer; the loose fiber layer prepared in the first opening is sent into the opener through the quantitative feeding roller for the second opening, and the Cotton fibers are dispersed into basic single fibers, which are sent to the next cotton box by a blower, and the volumetric method is us...

Abstract

The invention belongs to preparation of a filter material, in particular to a preparation method of a cotton fiber filter material, comprising the following steps: cotton staple which has the length of 2-15mm and the cotton content of above 90% is gradually changed into complete filament by adopting a triple opening and twice volume method for balancing uniformity finishing and a twice quantitative cotton feeding method, and then the complete filament is prepared into the cotton fiber filter material by the processes of air laid, glue spraying, drying and scrap edge lapping. The invention solves the deficiency that short and fine fiber is difficult to be used by a non-woven filter material in the prior art, and can use the short and fine fiber generally regarded as waste fiber in industryas a production raw material so as to protect environment, save materials and have low production cost, and the product performance can meet international standards, thus filling a gap of domestic air purification materials and being capable of earning foreign exchange through exports.

Description

Technical field [0001] The invention belongs to the preparation of filter materials, in particular to a preparation method of cotton fiber filter materials. Background technique [0002] It has been 30 years since my country's first non-woven filter material was developed in the non-woven fabric research laboratory of Shanghai Textile Academy in 1979. Glue - drying - trimming into rolls. The raw materials used are polyester, polypropylene and other chemical fibers. Due to the static electricity generated by the friction of the fibers, the finer fibers and short fibers are more difficult in the carding process, and the production is limited. [0003] Cotton fiber air filter material is widely used in the first air inlet of European and American series household central air conditioners. It is the primary air filter material. Its main function is to filter large particles of dust. It is a kind of short replacement cycle and short service life. Disposable filter material, so t...
