But under the specified conditions that this filter net cloth needs stability good, but become disadvantage；Filter cloth (is passed through through broadwise deformation coefficient
To the deformation extent with broadwise) it is greater than 10%, due to can also be bonded filter paper on filter cloth, after filter cloth deformation is excessive, filtering
Paper easily ruptures, and leads to filtration inefficiencies.
3. peel strength is small
Just there is good filter effect due to being bonded filter paper on filter cloth, this is just needed between filter paper and filter cloth
With biggish peel strength, filter paper and filter cloth can tightly fit together, and filter paper is not easy to take off from filter cloth
It falls.Promote the peel strength of filter cloth, it is desirable that web surface cannot be too bright and clean, and crude degree appropriate is advantageously pasted with filter paper
It closes；But the fabric manufacture equipment of knitted fabric requires yarn bright and clean, therefore the surface for being knitted fabric is very bright and clean, is unfavorable for improving
