Abstract
U ovom diplomskom radu ispitano je 15 različitih netkanih tekstila koji se razlikuju po sirovinskom sastavu (polipropilensko i poliestersko vlakno), površinskim masama (u rasponu od 97 g m-2 do 500 g m-2) te načinu učvršćenja (iglanje, iglanje i kalandriranje te učvršćenje termičkim putem uz pomoć vrućeg zraka). Svi uzorci su prošli sljedeće faze procesa izrade netkanog tekstila: pripreme vlakana, izrade runa na grebenaljci i polaganja na križnom polagaču. Nakon izrade runa dio uzoraka učvršćen je iglanjem, dio je učvršćen iglanjem i kalandriranjem, a dio je nakon grebenaljke i polaganja na križnom polagaču učvršćen termičkim putem prolaskom kroz vrući zrak. U radu su opisani proizvodni procesi i primarne karakteristike polipropilenskih i poliesterskih vlakana. Rezultati su prikazani u tablicama i grafikonima. Prekidna sila svih ispitanih netkanih tekstila veća je u smjeru suprotnom od izlaska materijala iz stroja (CMD). Veća prekidna sila u CMD smjeru karakteristična je za netkane tekstile proizvedene mehaničkim putem na grebenaljci te polaganjem runa na križnom polagaču. Uzorci učvršćeni termičkim postupkom imaju najmanju prekidnu silu. Uspoređujući netkane tekstile učvršćene iglanjem te s iglanjem i kalandriranjem vidljiv je utjecaj debljine na prekidnu silu, gdje povećanjem debljine netkanih tekstila prekidna sila raste. Prekidne sile uzoraka učvršćenih termičkim postupkom su najmanje. Zaključuje se da postupak učvršćenja i vrste sirovine značajno utječu na prekidnu silu netkanog tekstila dobivenog izradom runa mehaničkim putem.
Abstract (english)
In graduation thesis 15 different nonwoven fabrics differing in raw material composition (polypropylene and polyester fibers), mass per unit area (ranging from 97 g/m-2 to 500 g/m-2) and method of bonding (needling, needling and calendaring and thermal bonding with the hot air) were tested. All samples passed through following process phases of nonwoven fabric production: fiber preparation, web making on card and laying on the cross-lapping machine. After web making, one part of the samples were bonded by needling, second part by needling and calendaring while third part were bonded by passing through hot air. In thesis production processes and primary characteristics of polypropylene and polyester fibers were described. The results are presented in tables and graphs. The breaking force of all tested samples is larger in the cross machine direction (CMD). The larger breaking force in the CMD direction is characteristic for nonwoven fabrics produced on the carding machine and by web laying on cross-lapping machine. Thermally bonded samples have the smallest breaking force. The influence of nonwoven fabric thickness bonded by needling process and by needling and calendaring on breaking force is noticeable, where by increasing the thickness of nonwovens, the breaking force increases. The breaking forces of the thermally bonded samples are the smallest. According to obtained results it can be concluded that bonding process and raw material significantly effect on the breaking force of nonwoven fabrics produced by carding machine.
