Problems solved by technology
Due to the large thickness of the entire fiber elastic material, the temperature rise during vulcanization is not uniform enough, and the middle part is not fully vulcanized, which is easy to cause collapse, mold and insects, and affects the normal use of elastic materials.

Embodiment Construction
[0016] Embodiments of the present invention: according to the prior art, natural fiber filaments are prepared to obtain fiber sheets, and the fiber sheets are stacked and hot-pressed to obtain the natural fiber elastic material 1. When the fiber sheets are stacked, the natural fiber elastic material 1 Insert the air pipe in the middle, put the natural fiber elastic material 1 into the vulcanization tank 2, set the hot air pipe 4 in the vulcanization tank 2, connect the hot air pipe 4 with the air pipe 3, one end of the air pipe 3 is connected with the hot air pipe 4, and one end is closed . When vulcanizing, pass into hot air in vent pipe 3, and the temperature of hot air is 100~120 degree better. Raise the temperature in the middle of the natural fiber elastic material 1, make a plurality of micropores 5 on the vent pipe 3, and introduce hot air into the natural fiber elastic material 1.
[0017] After testing, the inner diameter of the vent pipe 3 is 2 to 5 centimeters, and...

The invention discloses a method and a device for intermediate vulcanization of a natural fiber elastic material, wherein natural fiber yarns are prepared to obtain fiber sheets, and the fiber sheets are superposed and hot-pressed to obtain the natural fiber elastic material. The method is characterized in that an aeration pipe is inserted among the fiber sheets when the fiber sheets are superposed, then the natural fiber elastic material is placed into a vulcanizing tank, the aeration pipe is connected with a hot air pipeline, and hot air is introduced into the aeration pipe to improve theintermediate temperature of the natural fiber elastic material. The vulcanization by the method and the device can improve the elasticity of the fiber elastic material and reduce the possibility of mould development and insect generation of the fiber elastic material. For a fibrous mat obtained through vulcanization, the water content after the vulcanization is lower, and almost no residual odor of the vulcanization exists, thereby improving the mildewproof grade of products, having better elasticity, and being more comfortable.
Description
technical field [0001] The invention relates to an intermediate vulcanization method and device for natural fiber elastic materials, and belongs to the technical field of natural fiber elastic material production. Background technique [0002] Natural fiber elastic materials refer to elastic materials made of natural fibers such as mountain palm and oil palm. In the prior art, natural fiber filaments are made to obtain a fiber sheet, and the fiber sheet is hot-pressed to obtain a fiber elastic material, and the entire fiber elastic material is put into a vulcanization tank for vulcanization and setting. Due to the large thickness of the entire fiber elastic material, the temperature rise during vulcanization is not uniform enough, and the middle part is not fully vulcanized, which is likely to cause collapse, mold and insects, and affect the normal use of the elastic material. Contents of the invention [0003] The object of the present invention is to provide a method an...
