Sažetak
Approx. 90% of the agrotextiles are made of synthetic polymers of PP, PE to a lesser extent from petroleum products such as PA and PET, which are becoming ecologically less acceptable. There is a trend of development of agrotextile production from natural fibres such as jute, wool, kenaf and cellulose regenerates (only 10%). Agrotextile for weed suppression is one of the wide range of products in agriculture application. The conventional material for weed suppression is black PE foil which, characterized by exceptional durability and significant effects regarding to its application. Negative aspects connected to their usage are long lifespan, high possibility of leaving harmful residues in the soil and the product itself is not recyclable. Conversely, biobased agrotextiles reduce negative impact on environment where during and after use are completely decompose making them ecologically acceptable. A preliminary investigation of durability of various fabrics used for weed suppression (affected by weathering) and also those potentially applicable natural fabrics (taking into consideration the degradation time and efficiency) was conducted for the purpose of further extensive research. All the obtained results are important indicators for further research that will be conducted within the project "Development of biodegradable nonwoven agrotextiles from natural and renewable sources" (KK.01.2.1.02.0270). This Project is a collaborative project of the Croatian textile factory Renotex tt and the University of Zagreb Faculty of Textile Technology, financed by the European Regional Development Fund. The Project aim is to develop a biodegradable nonwoven agrotextile for weed suppression and promotion of plant growth that will reduce or eliminate the use of chemical pesticides and insecticides. After fabric application, it will be completely composted in accordance with the principles of "zero waste" philosophy providing organic food production. Additional project aim is to introduce a more environmentally friendly production process of cleaner technologies which will have a significant impact on environmental protection and CO2 reduction. In general, plants are divided into annuals and perennials for which nonwoven agrotextiles are designed to compose considering time period of plant grow, maturation and fruiting. Nonwoven agrotextiles are produced by mechanical process on card, bonded by needlepunch and/or thermal bonded technology in wide range of mass per unit area (up to 500 g m-2). Nonwoven fabrics are produced from natural raw materials (Polylactide, Polyglycol, Copolymer poly (D, L- lactide-co-) in ratio 50:50 and 85:50, Rayon, Viscose and Bamboo fibres) emphasizing the environmental acceptability with regard to complete degradability after use. During degradation, beside the ability to reduce or eliminate weed grow ; it is considered that it will promote plant growth. The use of cellulose fibres and fibres from cellulose regenerates would continue the biological circulation of substances in the soil system (soil-plant) stimulating a plant growth as biological fertilizer. The result of the project is expected to be a product designed to maintain soil health, enhance growth glycolide and yield of plants without usage of pesticides and compostable after usage.
