The comparison of properties of polypropylene fibres intended for the production of agrotextiles | Primerjava lastnosti polipropilenskih vlaken, namenjenih za izdelavo vrtnarskih vlaknovin

Inglés. In the intensive horticulture various ways of protected area are used for the growth of seedlings and the cultivation of vegetables in all seasons. The easiest and the cheapest form of protected area is agrotextile which can be laid directly over field crops. Agrotextiles are nonwovens which are manufactured from textile fibers which are usually of chemichal origin. Textiles, used as a agrotextiles require suitable tensile strenght, and good permeability characteristics with no significant deterioration under the influence of weather changes. Properties of agrotextiles depend on the fibers made of and on the type and conditions of production. The aim of research was to analyse two types of polypropylene (PP) fibers (FiberVisionsR HY-Comfort and UV-stabilised PP fibers TrevonR) which are used for the production of agrotextiles and to compare the results with the declared properties and to present some methods for the analysis of the textile fibers. The research showed that there is a difference between measured and declared properties and that two types of PP fibers are different regarding textile-mechanical and structural properties.

Esloveno. V intenzivnem vrtnarstvu se za vzgojo sadik in pridelavo vrtnin v vseh letnih časih uporablja različne oblike zavarovanega prostora. Najenostavnejša in najcenejša oblika zavarovanega prostora je neposredno prekrivanje rastlin z agrotekstilijami. Agrotekstilije so vlaknovine, izdelane iz tekstilnih vlaken, ki so navadno kemičnega izvora. Od agrotekstilij namenjenih za prekrivanje vrtnin, se zahtevajo primerna trdnost in dobre prepustne lastnosti, ki se pod vplivom vremenskih sprememb ne smejo bistveno poslabšati. Lastnosti agrotekstilij so odvisne od vlaken, iz katerih so agrotekstilje izdelane, ter od postopka in pogojev izdelave. Namen raziskave je bil analizirati dva tipa polipropilenskih (PP) vlaken (FiberVisionsR HY-Comfort in UV-stabilizirana PP vlakna TrevonR), namenjenih za izdelavo vrtnarskih vlaknovin, primerjati rezultate z deklariranimi vrednostmi in predstaviti nekatere metode analize tekstilnih vlaken. Raziskava je pokazala, da prihaja med izmerjenimi in deklariranimi vrednostmi pri nekaterih lastnostih primerjanih vlaken do določenih razlik in da sta si preučevana tipa PP vlaken različna v tekstilno-mehanskih in strukturnih lastnostih.
