Dandanes na oblikovanje notranjosti avtomobilov bolj kot kadar koli prej vplivajo potrošniki. Ker so uporabniki avtomobilov v nenehnem stiku z avtomobilskimi sedeži, so prevleke sedežev postale eden izmed najpomembnejših dejavnikov, ki vplivajo na ugodje in dobro počutje uporabnikov avtomobilov. Tekstilije za oblazinjenje avtomobilskih sedežev so pomemben segment vizualne identitete vozila, zato je njihova zasnova izrednega pomena. Zahtevane lastnosti so predvsem odpornost proti obremenitvam, obstojnost proti drgnjenju, obstojnost proti UV-žarkom, odpornost proti statični elektriki ipd. V zadnjem desetletju proizvajalci avtomobilov oživljajo stare modele v novi preobleki in v svoje nove modele vključujejo retro elemente. Retro dizajn ne prinaša le prepoznavnega videza, ampak tudi razumevanje, kaj je bistvo novega modela avtomobila. Namen naloge je bil preskusiti primernost tehnologije ploskega pletenja za izdelavo prevleke avtomobilskih sedežev ter izbrati optimalno prejo oz. kombinacijo prej, ki zagotavljajo projektirane lastnosti pletiv za prevleke avtomobilskih sedežev. Cilj naloge je bil razvoj sodobne, trpežne in dimenzijsko obstojne pletene prevleke avtomobilskih sedežev z retro žakarskim vzorcem. Izbrani retro vzorec tkanine za prevleke avtomobilskih sedežev smo prenesli v dvofonturno žakarsko pleteno strukturo. Vzorce pletiva smo izdelali na industrijskem ploskem pletilniku SHIMA SEIKI SES 122 RT z delitvijo 12E. Za pletenje smo uporabili sukano prejo iz 100 % merino volne, za ojačitev strukture smo pri izbranih vzorcih vpletli poliamidni filament. Del vzorcev je bil apretiran proti gorenju z apreturnim sredstvom ECO-FLAM. Ugotovili smo, da je za preprečevanje nastanka vrečastih deformacij priporočljivo vpletanje poliamidnega filamenta v pleteno strukturo. Apretiranje proti gorenju ne poslabša elastičnih lastnosti pletiva. Z dodatkom ojačitvenega poliamidnega filamenta se zračna prepustnost pletiva zmanjša za približno 25 %. Apretiranje proti gorenju s sredstvom ECO-FLAM le malo vpliva na zračno prepustnost pletiva. Z dodatkom ojačitvenega poliamidnega filamenta ter apretiranjem proti gorenju se toplotna prevodnost pletiva poveča. Pletivo z dodanim ojačitvenim poliamidnim filamentom, apretirano s sredstvom ECO-FLAM je dobro obstojno proti drgnjenju in pilingu. Apretiranje s sredstvom ECO-FLAM je učinkovito. Pletiva iz 100 % volne ter volne z dodanim ojačitvenim poliamidnim filamentom so obstojna proti gorenju in tlenju.

• Title: Knitted car seat covers with retro patterns

Abstract

Today more than ever, car interiors are influenced by the consumer. Because car users are constantly in contact with the seats, seat covers have become one of the most important factors affecting the comfort and well-being of car users. Textiles used for car seat upholstery are an important segment of the vehicle's visual identity, so their design is of paramount importance. The required properties are mainly load resistance, abrasion resistance, UV resistance, resistance to static electricity, etc. In the last decade, car manufacturers have revived old models in new guises and incorporated retro elements into their new models. Retro design not only provides a recognisable look, but also an understanding of what the new car model is all about. The aim of the research was to test the suitability of flat knitting technology for the production of car seat covers and to select the optimum yarn or combination of yarns that offer the technical properties of knitted fabrics for car seat covers. The aim of the research was to develop a modern, durable and dimensionally stable knitted car seat cover with a retro jacquard pattern. We transferred the selected retro woven pattern for car seat covers into a double jacquard knitted structure. The knitting pattern was made on an industrial flat knitting machine SHIMA SEIKI SES 122 RT, gauge 12E. Twisted yarn made of 100% merino wool was used for knitting, and polyamide filament was incorporated into the selected samples to reinforce the structure. Part of the samples was treated with finishing agent ECO-FLAM for flame retardancy. We found that it is recommended to incorporate polyamide threads into the knitted structure to prevent the formation of bagging deformations. The flame retardant finish does not affect the elastic properties of the knitted fabrics studied. The addition of a reinforcing polyamide filament reduces the air permeability of the fabrics by about 25 %. The flame retardant treatment with ECO-FLAM has little effect on the air permeability of the fabric. The thermal conductivity of knitted fabrics increases with the addition of a reinforcing polyamide filament and the flame retardant finish. Knitted fabrics with additional reinforcing polyamide filament, finished with ECO-FLAM are abrasion and pilling resistant. Finishing with ECO-FLAM is effective. Knitted fabrics made of 100 % wool and wool with reinforcing polyamide filament are resistant to burning and smouldering.
