Abstract

U radu se definirala trajnosti netkanih agrotekstila proizvedenih od različitih vrsta vlakana i procesa proizvodnje koji su izloţeni uvjetima prirodnog starenja. Dan je pregled karaktistika samih vlakana, područje primjene, tehnologije.
U radu se provela analiza 7 uzoraka agrotekstila proizvedenih od polipropilenskog, polietilenskog, poliesterskog vlakna i regeneriranih materijala proizvedenim na grebenaljci i učvršćeni procesom iglanja ili kemijskim ispredanjem iz taline učvršćenih termičkim putem vrućim zrakom ili kalandriranjem. Uzorci su izloţeni uvjetima prirodnog starenja u trajanju od dva i četiri tjedna. Ispitala se površinska masa, debljina, vlačna svojstava i morfološka karakteristika površine agrotekstila mikroskopskom metodom. Proveden je preliminarno istraţivanje kako bi se ustanovio utjecaj uvjeta prirodnog starenja na agrotekstil, odnosno na koji način zemlja, voda, vjetar, UV zračenje i drugo utječe na svojstva, a samim time i na trajnost agrotekstila. Iz dobivenih prelimenarnih rezultata vidljivo je da prirodni uvjeti utječu na svojstva agrotekstila u vidu smanjenja površinske mase, debljine i vlačnih svojstava. Smanjenje navedenih svojstava nakon četiri tjedna izlaganja uvjetima prirodnog starenja na istraţene uzorke nije bitnije utjecalo.

Abstract (english)

The paper deals with defining the durability of nonwoven agrotextiles made from different types of fibers and production methods exposed to natural ageing conditions. The characteristics of the fibers themselves, the scope, technology and advantages of nonwoven fabric production.
This paper analyzes 7 nonwoven agrotextile made by polypropylene, polyethylene, polyester fibers and regenerates produced on card and boneded by needling or chemical spinning and bonded by hot air and calendering. The samples were exposed to natural ageing conditions for two and four weeks. The mass per unit area, thickness, tensile properties and morphological characteristics by microscopy of the nonwoven agrotextile were examined. A preliminary research was conducted to determine the effect of natural ageing conditions on agrotextiles, or how the earth, water, wind, UV radiation etc. affect the properties and therefore the durability of nonwoven agrotextiles. From the obtained preliminary results it can be seen that the natural ageing conditions affect on the nonwoven agrotextile properties in the form of reduction of mass per unit area, thickness and tensile properties. The decrease in the above-mentioned properties after four weeks of exposure to natural aging conditions did not significantly affect on the nonwoven agrotextiles.
