Description: The composite protective non-woven obtained by needle punching method consists of wool and chicken feathers. The non-woven fabric is intended for covering the grassy-bean mixture on difficult terrain (new dumps, heaps, railway embankments, ski slopes etc.) where getting a good sodding is very difficult. The non-woven fabric is characterized by high water capacity, adheres well to the ground, its ability to biodegradation within 2-3 months is about 70%. As a result of non-woven biodegradation the nitrogen released from wool and feathers enriches the soil with a nutrient, thanks to which it is not necessary to fertilize the ground with mineral fertilizers.
Long description (max 700 characters) Nowadays, environmental problems are of particular importance. Legislative policy forces industry to seek and use renewable resources including wastes of biological origin, that will be able to replace conventional petroleum based products. Taking into consideration the most abundant, unique and affordable waste streams that can be used to produce value-added products, the poultry industry cannot be bypassed. Waste from the poultry industry are: feathers, internal organs, blood, bones, skins and meat debris. Of these by-products, poultry feathers are the most potential for use. The main objective of the project is to create a concept of waste management methods and by-products from animal production, desirable from the point of view of economics and social effects. The project includes elaboration and creation , as a result of conceptual work and industrial research, the guidelines for the implementation of production the ecological nonwovens with the addition of feathers. The composite protective non-woven obtained by needle punching method consists of wool and chicken feathers. Elaborated nonwoven can be used in agriculture for covering the grassy-bean mixture on difficult terrain, eg. new dumps, heaps, railway embankments, ski slopes etc. The nonwoven fabric characterizes the following useful properties: light color, surface mass approx. 150-300 g / m2, good adhesive properties, large water capacity, appropriate structure. The non-woven protects the seeds and soil from washing off, limits the impact force of rain drops on soil aggregates, inhibits rain water runoff. On stony soils, most often on the slopes we are not able to cover all sown seeds with soil. Heavy nonwoven fabric, presses the seeds to the soil, covers them and improves the conditions for germination and seedling development. The properties of the nonwoven for rainwater retention and water resulting from dew formed during the night, and then its slow evaporation during the day due to the light color of the nonwoven - high albedo, is very important for young plants. The nonwoven fabric decreases the loss of ammonium nitrogen escaping from the soil to the atmosphere, it is a source of fertilizer components during its biodegradation. The investigation presented in this paper was carried out as a part of research project EkoPióro POIR.04.01.04-00-0059/17 „Development of innovative protective nonwovens with addition of feathers” . The project is co-financed by the European Union from the European Regional Development Fund under the Intelligent Development Operational Program. The invention is the subject of a patent application P. 430284 “Method for producing fluffy composite nonwoven fabric”.
