How To Protect Press Felt
1.For paper machine especially middle speed or high speed paper machine,the rational use of lubricating water now only benefit to the clean degree of the blanket but also produce a water film between the vacuum panel and blanket which play a role as a lubrication, sealing and cooling effect.
2.Vacuum panel slit between the two strips should be used the same material as the panel material or lower wear-resisting performance than the panel material. From the outside of the vacuum area from dense to sparse and with appropriate amount of lubricating water.
3.All supporting roller surfaces should be smooth without burrs and rust,and copper rollers, stainless steel rollers and rubber rollers are options.
4.There is a speed difference between the relevant transmission points, causing the blankets to rub and wear out.Adjust the speed ratio of each transmission point correctly to avoid the abnormal speed difference.
Single Layer paper machine felt is made up of single base layer fabric and fiber layer. Base layer is woven from synthetic filament or multi-filament. The structure is designed base on different paper machine, different press position and different type of paper.
Double Layer paper machine felt includes 1+1 composite structure and double layer of MD yarn structure. 1+1 composite structure BOM is consisted of two different thickness of base material. Both of these base materials can be changed to different construction and sizes to suit the requirement of different paper machines.
Triple layer paper machine felt includes 1 +2, 2 +1 and 1 +1 +1 composite BOM felt.
Applying to high speed of the paper machine for suction complex press, large diameter nip roll press and shoe press and can produce high-grade newsprint, write paper, paperboard etc.
