[0025] A kind of preparation method of the present invention is easy to lay drought-resistant slope protection type vegetation blanket, specifically comprises the following steps:

[0026] Step 1, get 80-120g dry waste cotton fiber, the jute fiber after 20-80g degumming, cut into average 8mm length respectively, it is mixed with 4-6gNa 2 CO 3 , 5-7gH 2 o 2 Mix with 5-30g of special additives, mix the raw materials with water (solid-liquid mass volume ratio is 1:8) and cook for 185min. Fully wash the cooked slurry, and then use a beater to beat the raw materials separately, control the beating degree of the slurry to 60°SR, and make a suspended slurry for later use. The configured suspension slurry is processed into a net, and the final square meter weight is (60-100) g / m 2 The surface layer is made of wet-laid nonwoven fabric;

Abstract

The invention discloses a manufacture method for drought-resistant and slope-protecting vegetation blankets. The manufacture method includes the following steps: preparing surface non-woven fabric forprotecting and fastening biomass crusts from jute fibers, waste cotton fibers and special assistants according to a wet non-woven technique, taking nutrient soil, crushed wheat straw and sedum lineare seeds as an intermediate seed layer, and preparing non-woven fabric for a water retaining layer from the jute fibers and the waste cotton fibers according to a needling non-woven technique. Comparedwith the prior art, the vegetation blankets produced by the manufacture method for the drought-resistant and slope-protecting vegetation blankets has the advantages of capability of being planted androlled in different places, low cost, easiness in laying, water storage, drought resistance and slope protection.

Description

technical field [0001] The invention belongs to the technical field of textile science and engineering, and in particular relates to a method for preparing an easy-to-lay drought-resistant slope protection type vegetation blanket. Background technique [0002] In the field of anti-drought slope protection engineering, the prior art often protects slopes, dams, and road slopes through methods such as vegetation concrete slope protection greening, rock slope planting matrix ecological protection, and grass planting plastic soil-fixing mats. There is the function of greening, but the slope greening effect of the prior art technology is not remarkable. Vegetation blanket technology is an engineering technology that can not only protect the slope, but also effectively improve the vegetation coverage of the slope. At present, there are many researches on vegetation blankets at home and abroad, which are mainly divided into the following types. One type adopts multi-layer laying m...
