Summary:The invention relates to a textile woven or knitted material used in the technology for plant cultivation. According to the invention, the material is a fabric made of degradable polyolefin fibers consisting of atactic and isotactic polypropylene with spherulitic structures which are deformed by spinning, the structure, in the crystalline area, comprising single-crystals with folded structure, and, in the non-crystalline area, a mixture of folded surfaces and crystal linking molecules, the thus obtained structure, having a yarn size of 400...600 dtex, is subjected further to UV radiation at a concentration of 8000...10 000 μW/cmfor 20...24 h in order to increase the degree of degradability. Invenţia se referă la un material textil, ţesut sau tricotat, utilizat în tehnologia cultivării plantelor. Materialul conform invenţiei este sub formă de ţesătură realizată din fibre poliolefinice degradabile, constituite din polipropilenă atactică şi izotactică, cu structuri sferulitice, care se deformează prin filare, structura fiind compusă, în zona cristalină, pe monocristale cu structură pliată, şi în zona necristalină, dintr-un amestec de suprafeţe pliate şi molecule de legătură între cristale, structura astfel obţinută, având o dimensiune a firului de 400...600 dtex, este supusă în continuare unei radiaţii cu raze U.V. la o concentraţie de 8000...10000 μW/cmp, timp de 20...24 h, pentru creşterea gradului de degradare.
