Paper felt is a fabric used in the paper industry for paper forming, dewatering and conveying of wet paper presses. The processing method is to first make a thin base fabric with synthetic fibers, and then lay a mixed fiber web of synthetic fibers and a small amount of wool, which is made by needling, chemical treatment, resin finishing and heat setting. Products require good dehydration, smoothness, abrasion resistance, dimensional stability, chemical resistance, antibacterial, heat resistance and hydrolysis resistance, etc.
The role of paper felts:
1. Water filtration effect: As a dewatering medium, when the paper web is dewatered in the vacuum box and the press area, the paper making felt absorbs and
Filter out any water that comes out of the paper.
2. Leveling effect: During the web transfer and dewatering process, it plays a role in leveling and modifying the surface of the paper.
3. The role of the conveyor belt: the paper sheet is transferred from the screen section through the press section to the drying section, and drives the passive roller and the cylinder mold operated.
The choice of paper making felt depends on the type of paper produced, the paper grammage and surface modification requirements, the type of paper machine, the environmental conditions in which the felt are used, and the existing carpet cleaning and purification equipment. When the paper surface modification requirements are more stringent, the longitudinal and lateral yarns of the felt bottom net should be thinner, and the structural design requires a smooth surface. High-speed and wide-width paper machines require good strength and stability of the felt, and the grooves, blind holes, and vacuum press rolls require the felt to be stronger. When the press load is high and the surface of the press roller is hard, the mechanical properties of the felt are higher. The blanket configured with high-pressure water washing requires good flocking fastness
The crescent tissue paper machine is high speed paper machine ,so it requires the felt should be more strength and stability .
Special papermaking blanket for high-speed household paper adopts advanced bottom-net weaving technology and multi-axial bottom-net structure.

|6.||Bottom wire||Double wire|
The 15.0M wide heavy-duty loom imported from the Swedish TEXO company and the Master SM 92 high-speed loom imported from the Italian Somet company were used to weave the bottom net. The wide-width hot oil roller setting machine adds pressure, water washing, vacuum suction, chemical treatment, and scorching to shape and arrange the felt.
This product has the advantages of good initial adaptability, fast speedup, stable operation, soft paper production without any holes, can effectively save steam consumption and power consumption, and stable performance during use. The service life is basically equivalent to imported papermaking blankets , Is a very cost-effective papermaking blanket.
This product can meet the demand of medium and high-end household paper production by crescent paper machine above 1100m / min
