Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0025] The invention is a high-strength non-woven fabric for paper-making rubber rollers, which is made of aramid 1414 fibers through a hydroentanglement process. The specific production process is: A. Opening: the aramid fiber is accurately weighed by an electronic scale, and then quantitatively transported to the rough opener for preliminary opening of the aramid fiber; Cotton box, to mix the aramid fiber evenly, and add 5% conductive fiber at the same time; then send the aramid fiber to the fine opening machine, where the fiber raw material is finely opened to make the fiber more fluffy;

[0026] B. Carding: Feed the finely opened aramid fibers into the...

Abstract

The invention disclose a papermaking rubber roller with high-strength non-woven and the production process which is made by aramid fiber through spunlaced process. The production process comprises the following steps: A. Opening; B. Combing; C. Lapping: putting fiber web into lapping machine and crosswise lying are called lapping; D. Drafting: the lapping is slowly dragged trough drafting machine to reduce vertical and horizontal force ratio difference of drafting; E. Spunlace: lapping which is finished by drafting does spunlaced reinforcement by using spunlace machine. Since aramid fiber has the excellent performances of super strength, high modulus and heat resistance, acid alkali resistance, light weight, insulation, aging resistance and long life cycle and the like. The high-strength non-woven which is made by adopting the above-mentioned technical proposal has the advantages of heat and high voltage resistance, good anti-aging performance and long service life and can meet operating requirements of the papermaking rubber of high speed paper machine.

Description

technical field [0001] The invention relates to non-woven fabrics, in particular to high-strength non-woven fabrics for papermaking rubber rollers and a production process thereof. Background technique [0002] The role of papermaking rubber rollers is to squeeze out and dry the moisture in the paper, and at the same time make the paper thinner. Generally, there are 8 to 16 pairs of rubber rollers in the papermaking production line. The rubber rollers are usually used in pairs. The inside of the rubber rollers is a steel pipe. The outer coating layer is formed by coating the base fabric (non-woven or woven fabric) with slurry or resin. [0003] In the past, due to the low speed of the paper machine, the temperature of the rubber roller was only about 150°C, and the service life of the rubber roller was only half a year, and the pressure was also small, about 50N / cm 2 Left and right, nylon woven fabric or other materials can meet the requirements of use. With the developmen...
