Nutritional geotextile is composed of a layer of non-woven fabric and a layer of animal and plant fiber felt. The filament geotextile is produced by needle-punched non-woven technology. It is a new type of geotextile researched for greening concrete masonry materials. The animal protein fiber can provide nutrients for plant growth after decomposition, so it is named.

Nutritional geotextile is a kind of repair product that is used to lay under the green concrete plate and help the growth of plants. It has many advantages in performance, and this non-woven geotextile can be evenly laid under the green concrete plate, and a layer of felt that can slowly decompose the nutrients required by plants is compounded on the surface of the non-woven fabric.

While basically maintaining the anti-filtration performance of non-woven geotextile, it provides long-term slow-release fertilizer for the plants on the concrete of the green belt, and solves the problem of insufficient slow-release fertilizer in the filling material due to the limited space in the green concrete gap. Nutritional polyester non-woven fabric, also known as filament nutritional geotextile, is made by using polyester filament non-woven geotextile and natural fibers such as PROT and L, and adopting composite nonwoven process, which is composed of non-woven layer and nutrient layer.

Generally, the width is less than or equal to 5.6 meters, the length is between 50 meters or 100 meters, the weight is 200g-400g per square meter, and the strength is higher than that of ordinary nutritious geotextile. It has been widely used by construction units in recent years. Planting grass on nutritious geotextile can achieve high survival rate of vegetation and rapid greening. After a period of growth, it can become a beautiful lawn loved by everyone. It has greatly saved time and cost.

Through the application of the nutrient geotextile, better environmental restoration and reconstruction effects were obtained, which effectively provided nutrients for plants on the greening concrete, and the grass grew well. It can also match the required grass seeds according to the landscape requirements to achieve good ecological and landscape effects. Therefore, the nutritious geotextile is a kind of geotextile product of municipal greening and restoration type, which can achieve the value and purpose of landscaping while basically maintaining the filtration performance of the filament geotextile.
