Description

A kind of air filtration increases progressively filter bag cotton

Technical field

The utility model relates to air filtration industry, is specifically related to a kind of air filtration and increases progressively filter bag cotton.

Background technology

In the industrial production, some places easily producing dust need to carry out dust removal by filtration to air, generally use filter cotton, filter etc.But the leaf filter common at some annular spaces is inapplicable, need to use bag type filter device.

As filter element, air filter bag is key one ring in filter process, and the quality of air filter bag determines the filter effect of user to a great extent, and the filtration Quality of air filter bag depends primarily on the quality of air filter bag cotton.

All the time, the filter bag material of the making industry production of air filter bag cotton, all after special process processing, on blanching make-up machine, scald one side with ultra-fine material, fines again, namely blanching is melted fiber and is plated together, that it changes the structure of fiber, make filter bag material resistance large, ventilative ability, does not welcome by user.

The air filter bag of prior art is cotton, and its formula fiber is generally in following two kinds of ratios mixing:

1、4D:30﹪；3D:35﹪；7D:35﹪；

2、4D:30﹪、3D:35﹪、1.5D:35﹪。

The air filter bag of prior art is cotton, and its production process is: fiber completes through operations such as shredding, combing, lapping, shaping, hot melt, sizing, rolling, blanching, rolling, packagings.

There is following shortcoming in the air filter bag cotton of prior art: ventilative ability, dust containing capacity are little, filtering surface resistance large, poor filtration effect, cost are high, service efficiency is low.

Summary of the invention

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the air filtration that a kind of ventilative power is strong, dust containing capacity is large, resistance is little, cost is low, service efficiency is high, filter effect is better, filter rank higher and increases progressively filter bag cotton.

For solving problems of the prior art, the concrete technical scheme of employing is:

A kind of air filtration increases progressively the filter bag bale of cotton and draws together thin layer and lower close layer; Described each component of thin layer and the mass parts of each component are respectively: length is the 7D polyster fibre 20 parts of 64mm, and length is the 15D polyster fibre 25 parts of 64mm, and length is the 20D polyster fibre 25 parts of 64mm, and length is the 4D polyster fibre 30 parts of 51mm; Described each component of lower close layer and the mass parts of each component are: length is the 3D polyster fibre 25 parts of 64mm, and length is the 1.2D polyster fibre 25 parts of 38mm, and length is the 7D polyster fibre 25 parts of 64mm, and length is the 15D polyster fibre 25 parts of 64mm.

The preparation method that this air filtration increases progressively filter bag cotton comprises the following steps:

Step S1, be the 7D polyster fibre of 64mm respectively by 20 mass parts length, 25 mass parts length are the 15D polyster fibre of 64mm, 25 mass parts length are the 20D polyster fibre of 64mm, 30 mass parts length are that the 4D polyster fibre of 51mm adds the first opener, through combing, lapping, shaping after formed and upper dredge layer; Be the 3D polyster fibre of 64mm respectively by 25 mass parts length, 25 mass parts length are the 1.2D polyster fibre of 38mm, 25 mass parts length are the 7D polyster fibre of 64mm, 25 mass parts length are that the 15D polyster fibre of 64mm adds the second opener, through combing, lapping, shaping after, then form lower close layer after needing machine acupuncture;

Step S2, is laid on upper thin layer on lower close layer, and after hot melt, sizing, rolling, namely obtained air filtration of the present utility model increases progressively filter bag cotton.

Preferred scheme further, in described step S2, the temperature of hot melt is 215 DEG C.

By adopting such scheme, a kind of air filtration of the present utility model increases progressively filter bag cotton and preparation method thereof compared with prior art, and its technique effect is:

1, the utility model is dredged lower close filter bag material to scald without blanching make-up machine, lapping aperture when not changing production, ventilative power is strong, and blast is little.

2, the utility model is dredged lower close filter bag material to scald without blanching make-up machine, and air intake surface is that crude fibre is fluffy, dust containing capacity is large, improves 30 ﹪ than existing filter bag material.

3, upper part of rarefaction divides employing crude fibre, and lower compact part divides employing superfine fibre to make through the special process of acupuncture, hot melt, can filter more than 0.03 micron particle diameter, good filtration effect.

4, on the utility model, thin lower close filter bag material scalds without blanching make-up machine, and keep lapping, hot melt, modular in design aperture, the saturating power of wind is strong, and resistance is little, and filtration rank is high.

5, the utility model is dredged lower close filter bag material to scald without blanching make-up machine, save process cost.Cost saves 30 more than ﹪ than existing product, and cost is low, and service efficiency is high.
