High-strength plant fiber material

Abstract

The invention discloses a high-strength plant fiber material. The high-strength plant fiber material comprises plant-fiber elastic sheets, wherein the direction of the plant-fiber elastic sheets from a production line is used as the longitudinal direction; the direction of the plant-fiber elastic sheets vertical to the production line is used as the horizontal direction; more than one layer of longitudinal elastic sheets and more than one layer of horizontal elastic sheets are stacked to obtain the plant fiber material; and long sisal-hemp layers are arranged between the longitudinal elastic sheets and the horizontal elastic sheets. The high-strength plant fiber material disclosed by the invention has the advantages that the plant-fiber elastic sheets are staggered and stacked in the longitudinal and horizontal directions, so that the strength of the stacked plant fiber material can be improved, the used quantity of the plant-fiber elastic sheets can be reduced and the effect of reducing the cost can be achieved; simultaneously, the size change of the plant fiber material produced by adopting a staggered lamination mode is relatively small; when the plant fiber material is finally cut and sized, the cutting quantity can be reduced; and the long sisal-hemp layers are arranged between the longitudinal elastic sheets and the horizontal elastic sheets, so that the plant fiber material has the relatively high elastic performance and the relatively good toughness.

Description

technical field [0001] The invention relates to a plant fiber material, in particular to a high-strength plant fiber material. Background technique [0002] The plant fiber material is made of natural plant fibers. The plant fibers made of this material include mountain palm, coconut shell, oil palm, hemp, bamboo, etc. These plant fibers are made into layers of elastic plant fibers. After the sheets are stacked, the plant fiber elastic material can be obtained. The plant fiber elastic material can not only be used to make mattresses, but also seat cushions, back cushions, pillows, sound insulation materials, shock absorption materials, and the like. Chinese Patent No. 90100464.2 discloses a production method of plant fiber elastic material. The plant fiber filaments are crimped and blown into a three-dimensional distribution shape with air flow and then sprayed with glue to bond the nodes between the brown filaments to obtain a plant fiber elastic sheet. The elastic sheets ...

Problems solved by technology

The applicant found that there are some problems in this kind of stacking method: the original lamination process of all plant fiber elastic materials is stacked along the direction of the production line, resulting in irregular large sizes of elastic materials during subsequent vulcanization Changes, and the strength of elastic materials in different directions is different. The strength along the production line is high, while the strength perpendicular to the production line is low. The mechanical properties of elastic materials are inconsistent in all directions, so elastic materials often appear in the process of use. Collapse, bulging and other series Quality issues

[0003] Moreover, the current plant fiber materials need a good processing technology to improve the quality of the product, and improving the strength of the material is one of the important links. How to improve the strength of the material under the premise of controlling costs is a headache for producers. The problem
