Abstract:Diplomska naloga obravnava analizo nateznih lastnosti vlaken v fazi priprave prediva za mikalniški postopek izdelave netkanih tekstilij z namenom ugotoviti, ali prihaja v tej fazi do kakršnih koli poškodb oz. zmanjšanja nateznih lastnosti vlaken. Analiza nateznih lastnosti vlaken se nanaša na konkretno procesno linijo priprave prediva različnega surovinskega sestava, finosti in dolžine vlaken (predivo iz PES vlaken, PP vlaken, meta aramidnih vlaken ter iz mešanice PAN vlaken z različno finostjo in dolžino) za izdelavo kopren, v katero so vključene naslednje tehnološke faze: klimatizacija in relaksacija prediva, obzirno rahljanje, intenzivno rahljanje, mešanje prediva, odmerjanje določene količine kosmičev, intenzivno rahljanje in dovajanje kosmičev. Vzorci prediva so bili odvzeti na treh mestih, in sicer iz skladišča, po mešanju prediva iz mešalne komore in iz dozirnika kosmičev, nameščenem tik pred mikalnikom. Natezne lastnosti so bile izmerjene v skladu s standardom SIST EN ISO 5079. Rezultati analize nateznih lastnosti so pokazali, da v fazi priprave prediva konkretnega proizvajalca netkanih tekstilij ne prihaja do poškodb vlaken.

Title:Tensile properties analysis of fibers during the preparation of fibrous material for carding of web forming
Abstract:The diploma work deals with the analysis of the tensile properties of fibres during the preparation of fibrous material for carding process of web forming in order to find out if some damages of fibres or reductions of tensile properties of fibres occur during this phase of web production. Analysis of fibres’ tensile properties is focused on the fibrous material preparation line of certain nonwoven producer, which consist of the following technological phases: relaxation and conditioning – bale opening – intensive loosening – blending – feeding – intensive loosening and batt forming. The fibrous material with different fibre’s type, fineness and length (fibrous material from PES, PP, and meta-aramid fibres, and fibres from the mixture of two different PAN fibres regarding fineness and length) were taken into account. The fibrous material samples were taken at three points, namely from the store, after the blending from the blending chamber, and from the chute feed, located just before the carding machine, and tested according to the SIST EN ISO 5079. The results show no fibres’ damages during the fibrous material preparation phase of certain nonwovens producer.
Keywords:production of nonwoven fabrics, preparation of fibrous material, carding method of web forming, tensile properties of fibers
