Problems solved by technology

However, the stability of conventional environmental protection ecological bag materials is poor. When exposed to outdoors for a long time, the ability to resist ultraviolet rays and electromagnetic waves is poor, and it is easy to decompose and oxidize, which reduces the strength of the ecological bag and shortens the service life.

Abstract

The invention relates to the technical field of non-woven fabrics, in particular to ultraviolet-resistant environmental-protection ecological cloth and a preparation method thereof. The ultraviolet-resistant environmental-protection ecological cloth comprises the following raw materials in weight percentage: 6-8 percent of modified polypropylene batch and 92-94 percent of polypropylene slice. Theultraviolet-resistant environmental-protection ecological cloth adopts the modified polypropylene batch and the polypropylene slice as raw materials, and thereby, the cloth has good ultraviolet resistance, water absorbability and water-retaining property and is beneficial to plant growth.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an anti-ultraviolet environment-friendly ecological fabric and a preparation method thereof. Background technique [0002] With the rapid development of the world economy, the flooding of rivers and soil erosion caused by global warming are increasing, and the acceleration of urbanization will also cause the per capita green area to become smaller and smaller. The use of environmentally friendly ecological bags can protect green It has a remarkable effect on vegetation and preventing soil loss. However, the stability of conventional eco-friendly ecological bag materials is poor. When exposed outdoors for a long time, the ability to resist ultraviolet rays and electromagnetic waves is poor, and it is easy to decompose and oxidize, which reduces the strength of the ecological bag and shortens the service life. Contents of the invention [0003] The object of the present...
