A kind of manufacturing method of polyester fiber electric heating non-woven paper

Abstract

The invention provides a manufacturing method for polyester fiber electric heating non-woven paper, and belongs to the technical field of manufacturing of electric heating plates. The raw materials in the method comprise short carbon fibers and polyester staple fibers, the short carbon fibers and the polyester staple fibers are weighed according to a certain proportion, the short carbon fibers are dried and the polyester staple fibers are processed in an opening mode before the short carbon fibers and the polyester staple fibers enter a cotton blender machine, the short carbon fibers and the polyester staple fibers are combed through a combing machine, are subjected to lapping and redirection processing through a lapping machine and are combed again to be completely and evenly mixed, and finally, the short carbon fibers and the polyester staple fibers are subjected to high-temperature heat press to form the polyester fiber electric heating non-woven paper in a squeezing and compounding mode without any auxiliaries and additives. The polyester fiber electric heating non-woven paper is excellent in performance, uniform in thickness, uniform in carbon fiber distribution, high in strength, high in water resistance, resistant to acid and alkali, reliable in quality and long in service life, and has certain stretching performance.

Description

(1) Technical field [0001] The invention relates to a manufacturing technology of an electric heating plate, in particular to a manufacturing method of polyester fiber electric heating non-woven paper. (2) Background technology [0002] Carbon fiber is currently the most advanced electric heating element in the world. It is a high-tech product used by aerospace military to civilian use. It uses electricity as energy and radiates heat energy through far-infrared electromagnetic waves. It is a new heating method and a new breakthrough in the heating field. The polyester staple fiber is obtained by spinning polyester into tow and cutting it. The polyester fiber has high strength and good elasticity, and has the characteristics of constant water absorption and strength. The strength of polyester fiber is nearly twice as high as that of cotton and higher than that of wool. 3 times, 5 times higher than wood pulp fiber, so polyester fabric is strong and durable, can be used at 70 ~...

AI Technical Summary

Problems solved by technology

[0003] At present, the carbon fiber heating material adopts the papermaking process to produce thermal paper by mixing pulp and carbon fiber. The disadvantage is that the production process is complicated, and it is difficult to fully mix carbon fiber and wood pulp fiber in water due to their different proportions. The biggest disadvantage is the water resistance of electric heating paper. The strength is very low, there is no stretching elasticity, and it is easy to delaminate. During the lamination process of the electric heating paper and the insulating cloth, the insulating resin dissolves the wet electric heating paper, which greatly reduces the paper strength. The electric heating paper is very weak during the pressing process of more than 1000 tons It is easy to crack, and the electric heating plate is easy to delaminate or crack due to the lack of stretching and elasticity of the electric heating paper under repeated heavy external pressure during use, resulting in failure of the electric heating plate and short product life.
