Abstract
The invention provides degradable green plant felt made from water storage nanofibers. The degradable green plant felt comprises a degradable non-woven fabric composite layer and a water storage nanofiber layer which are arranged from bottom to top. The degradable non-woven fabric composite layer comprises a top sheet and a bottom sheet. A plurality of vertical separation sheets are arranged between the top sheet and the bottom sheet. The space between the top sheet and the bottom sheet is divided into a plurality of independent cavities through the vertical separation sheets. The independent cavities are filled with plant fiber powder, and the tops of the independent cavities are fully provided with through holes. The water storage nanofiber layer is a crude fiber layer and fine fiber layer assembly made from polylactic acid in a melt-blowing mode. A crude fiber layer serves as an upper layer, and the diameter of fibers ranges from 700 nm to 900 nm. A fine fiber layer serves as a lower layer, and the diameter of fibers ranges from 300 nm to 500 nm. The invention further provides a making method of the degradable green plant felt. The degradable green plant felt has a good desert water storage effect, is made of degradable materials, and is environmentally friendly, the plant fibers can also serve as plant nutrients, and an effective guarantee is provided for survival of green plants in a desert.
Description
technical field [0001] The invention belongs to the technical field of materials for controlling deserts, in particular to a degradable green plant mat made of water storage nanofibers and a preparation method thereof. Background technique [0002] The phenomenon of desertification has seriously threatened the living environment of human beings and the development of social economy. At present, the area of desertification in my country has reached 2.62 million square kilometers, accounting for 27% of the country's land area, and it is constantly expanding. At the same time, my country is also the largest desert area in the world. It is one of the countries with large size, wide distribution and serious desertification hazards. Desertification not only causes the imbalance of the ecosystem, but also shrinks the area of arable land, which has a serious impact on my country's industrial and agricultural production and people's lives. The desert and desertified land in the a...
