Abstract
This study examines the stretch properties of nine variants of single-tuck weft-knitted fabrics made from 31 tex ×2 wool/PAN yarn and compares them with a plain fabric. The research emphasizes how variations in the arrangement and percentage of tuck loops within the stitch repeat affect the fabrics' stretch characteristics. Results show that the presence and percentage of tuck loops at the width repeat significantly influence stretch properties. The plain fabric displayed apparent anisotropy, with widthwise deformation roughly four times greater than lengthwise deformation. This behaviour was largely dominated by the elastic component, indicating strong immediate recovery and dimensional stability. In contrast, tuck stitch variants showed more balanced deformation between directions, reflecting the moderating influence of tuck loops on fabric anisotropy. Increasing the percentage of tuck loops improved lengthwise extensibility while decreasing widthwise recovery, thereby altering elastic and residual deformation behaviour. The analysis of deformation components revealed that tuck loops decrease the elastic deformation ratio and increase delayed and residual deformation, suggesting greater stress relaxation and a higher permanent set. These results highlight the sensitive interplay between the presence and combination of knit and tuck loops and their effects on loop configuration and fabric mechanics. The results thus confirm that the controlled use of tuck stitches provides a practical approach to optimizing fabric performance in terms of stretch, recovery and stability, thereby offering valuable insights for designing functional and high-performance knitted textiles.

Title:Vpliv različic razporeditve lovilnih petelj na raztezne lastnosti levo-desnih votkovnih pletiv iz mešanice volna/PAN
Abstract:
V raziskavi so bile proučene raztezne lastnosti devetih različic levo-desnih lovilnih votkovnih pletiv in primerjane z lastnostmi enostavnega levo-desnega pletiva. Pletiva so bila izdelana iz preje z dolžinsko maso 31 tex × 2, iz mešanice volna/PAN. V raziskavi se je ugotavljal vpliv različic razporeditve in deleža lovilnih petelj (Tn) v sosledju na raztezne lastnosti pletiv. Enostavna pletena struktura kaže izrazito anizotropijo; deformacija v prečni smeri je približno štirikrat večja kot v vzdolžni smeri. Pri takšnem obnašanju pletiva pretežno prevladuje elastična komponenta deformacije (E1), kar kaže na visoko takojšnjo elastično povratnost in dobro dimenzijsko stabilnost. Nasprotno pa strukture z različno razporejenimi lovilnimi petljami kažejo bolj uravnoteženo deformacijo v obeh smereh, kar pomeni zmeren vpliv lovilnih petelj na anizotropijo pletiva. Z naraščajočim deležem lovilnih petelj se povečuje razteznost v vzdolžni smeri, hkrati pa se zmanjšuje elastična povratnost v prečni smeri, kar vpliva na spremembo razmerja med elastično in trajno deformacijo. Analiza komponent deformacije je pokazala, da lovilne petlje zmanjšujejo delež elastične deformacije (E1/E) ter povečujejo delež zakasnele (E2/E) in trajne deformacije (E3/E), kar kaže na večjo sprostitev napetosti in večjo trajno deformacijo pletiv. Rezultati poudarjajo ključen vzajemni učinek zank in lovilnih petelj ter njihov vpliv na konfiguracijo zančne strukture in mehanske lastnosti pletiv. Rezultati raziskave potrjujejo, da je nadzorovana uporaba lovilnih petelj učinkovit pristop k optimizaciji uporabnih lastnosti pletiv, kot so razteznost, povratnost in dimenzijska stabilnost, ki so pomembne za razvoj funkcionalnih in visokozmogljivih pletenih tekstilij.
