Device and method for fabricating forming fabric with rapid dehydration property

Abstract

The invention relates to a device and a method for fabricating forming fabric with a rapid dehydration property. The device comprises a spinning device and a high-frequency electromagnetic heating coil, wherein the spinning device comprises a surface layer tube and a core layer tube arranged in the surface layer tube concentrically in a sleeving manner, and the surface layer tube and the core layer tube are both connected with respective pressure supply devices; an annular intermittent vibration device is attached to the peripheral surface of the surface layer tube in a sleeving manner, and the vibration frequency of the intermittent vibration device is adjustable. The method for preparing the forming fabric with the rapid dehydration property comprises the following steps: (1) the surface layer tube and the core layer tube are used for performing spinning towards a spinning liquid simultaneously, the intermittent vibration device transmits own vibration into the surface layer tube and the core layer tube, and the radial size of the core layer increases with decrease of the radial size of the surface layer in the axial direction of the fibers due to vibration; (2) the fibers prepared in the step (1) are combined to fabricate yarn, and the forming fabric is woven with the yarn; (3) the high-frequency electromagnetic heating coil is used for heating the forming fabric, and the fiber conductive core layer is enabled to produce heat.

Description

technical field [0001] The invention relates to a manufacturing equipment and process of a forming net, in particular to a manufacturing device and a manufacturing method for a rapid dehydration forming net. Background technique [0002] In recent years, China's paper industry has developed rapidly. Not only have many new pulp and paper technologies emerged, but pulp and paper equipment has also been constantly updated. The modern papermaking forming wire is an extremely important dewatering equipment, which is closely related to the web forming of the wire, and the web forming condition of the wire determines the final paper performance. As an important dewatering forming equipment in the wire section, the paper forming wire must have the following properties: (1) stable and fast dehydration ability; (2) good retention of fine fibers and fillers; (3) good dimensional stability ; (4) Long service life in line with paper machine conditions. [0003] The warp density and wef...

Problems solved by technology

[0003] The warp density and weft density of the forming fabric are important factors affecting the dehydration speed of the forming fabric. If the warp density and weft density are too large, the dehydration speed will be too slow, which will affect the production efficiency. If the warp density and weft density are too small, the fine fibers will and reduced retention of fillers
