Polyester Single Layer Dryer Press Felt for Paper Machine Cloth

Are you bothered by Felt Lint and Abrasion?
Don't Worry. Let SUN HONG tell you the reason and the solution.

Reason:
There are many reasons for the damage and the lint of the felt, mainly two of which are scraped by machine parts and chemical damage.
1.The most common reason is that the surface of the press felt torn loosened by high pressure water.
2.Lack of lubricating water between the vacuum panel and the blanket, which causes the temperature rise and the fiber is damaged.
3.Material of Vacuum suction cover is bad,large in friction coefficient, the edges of the cover and the seam has burrs or with sharp blade shaped, without rounding out the edges,the wrap Angle between the vacuum box and blanket is too large, high vacuum degree, local surface irregularities,fixed screw exposed,the above will lead to blanket abrasion .
4.Supporting roller surface with burrs, iron molds , the roller surface wrapped with slurry, or expander roller rubber thread stand is too high or stand has obvious edges and corners,no sharp edges exists between eight openings and rubber roller body or the high and low transition zone is too short, etc are likely to cause blanket abrasion .

Solution:
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.

What is Paper Making Felt
Paper making felt can be divided into three types: wet press felt, pick up felt and dryer felt according to the uses.
Paper making felt possess good air permeability, mark-less, heat resistance, wet resistance, anti-aging, structure stability, anti-worn out, dimensional stability, excellent tensile strength, high linear pressure, easy to operate, long life performance.

According to paper machine and paper, we can change the structure of base mesh. It has the characters of anti-high pressure, good elasticity and filter ability, stable size, small elongation, great strength, effective to eliminate grooving, vacuum mark, blind-hole mark and other marks. Suitable to vacuum press, kinds of complex press and other press for producing high grad offset paper, and kinds of high grade paper and paper board etc.
Structure

BOM Felt is composed of bottom net layer and fiber layer. The bottom mesh layer is made of monofilament, monofilament and multifilament composite chemical fiber materials. The single layer, double layer, multi-layer (1 + 1, 1 + 2, 2 + 2) and other organizational structures are made by using different weaving technologies; the common synthetic fibers in the fiber layer mainly include nylon staple fiber, polyester staple fiber and other fiber raw materials; the staple fibers with the same or different thickness are laid in layers on the bottom net, and then The bottom mesh layer and fiber layer are processed by needling, heat setting and other special post finishing processes to make BOM felt.

Function

1.Water filtering function:As a dehydration medium, when the paper sheet is dehydrated in the vacuum box and press area, the paper blanket absorbs and filters out the water from the paper sheet.
2. Leveling effect:In the process of web transfer and dehydration, it can smooth and modify the paper surface.
3. Function of conveyor belt:The paper is transferred from the net part to the drying shaft through the pressing part, and the passive roller and net cage are driven to run.
