In this research, bending and drape properties of woven fabrics and the effect of weft density, weft yarn count and warp tension on these properties were investigated. Higher values were found for bending rigidities of the fabrics woven with thicker weft yarns and at higher weft densities. It was seen that bending rigidities of the fabrics in the warp directions increased as warp tension increased. Bending rigidities in the weft directions did not show any significant change, such as an increase or decrease depending on any change in warp tension. In the case of the fabrics woven with thicker weft yarns, the overall fabric bending rigidity increased as warp tension increased. Considering drape coefficients of the fabrics, it was observed that the drape coefficient increased as the weft density increased and weft yarn became thicker. The drape coefficient did not significantly vary depending on the variations in the warp tension.
In this research, the bending property of jacquard woven fabrics and the effects of weft density, weft yarn count, weave, and Lycra inclusion in weft yarn on this property were investigated. Viscose filament warp yarn and polyester and polyester/Lycra weft yarns were used for weaving fabrics, and 4/1 and 7/1 satin weaves with the same jacquard design were used as the ground weave. Experimental results show that the bending rigidities of the fabrics in the warp directions increase as the weft density increases and the weft yarn gets thicker. The bending rigidities of the fabrics woven with a 4/1 satin weave in the warp direction are higher compared to the bending rigidities of the fabrics woven with a 7/1 satin weave in the same direction. Similar to the bending rigidities in the warp direction, as the weft density increases and the weft yarn gets thicker, the bending rigidities of the fabrics in the weft directions increase. When the weft yarn includes Lycra, the bending rigidity values of the fabric decrease in the weft direction. Additionally, similar to the bending rigidity in the warp direction, the jacquard woven fabrics with a 4/1 satin weave have a higher bending rigidity in the weft direction compared to the jacquard woven fabrics with a 7/1 satin weave. It was observed that when the weft density increases, the overall bending rigidities of the fabrics increase. Despite fabrics woven with a polyester/Lycra weft yarn having a thicker weft yarn and heavier weight with the same weft density and weave compared to fabrics woven with a polyester weft yarn, the bending rigidity values in the weft direction have a lower overall fabric bending rigidity.
Analiza proprietăților de confort termofiziologic ale țesăturilor 100% acrilice și în amestec acril/bumbac, acril/viscoză și acril/PES În acest studiu s-au investigat proprietățile de confort termofiziologic ale țesăturilor produse cu fir de bătătură 100% acril, bumbac, viscoză și PES, precum și în amestec acril/PES, actil/bumbac și acril/viscoză. În acest scop, 35 de țesături diferite au fost realizate din fire acrilice în urzeală și fire de bătătură din acril, bumbac, PES, viscoză, acril/bumbac, acril/viscoză și acril/PES, cu trei desimi diferite de bătătură și legături pânză, diagonal și atlaz. Analiza rezultatelor a arătat că nu s-a observat efectul naturii firului și al desimii bătăturii asupra rezistenței termice. S-a observant că tipul de legătură a avut un efect asupra rezistenței termice, absorbției termice și permeabilității la aer a țesăturilor. Valorile permeabilității la aer ale țesăturilor cu legătură pânză au fost mai mici decât cele ale țesăturilor cu legăturile diagonal și atlaz. Permeabilitatea la aer a scăzut odată cu creșterea desimii firelor de bătătură. Conform evaluării statistice, tipul de fir sau natura firului a avut un efect semnificativ asupra rezistenței la vapori de apă, în timp ce desimea firelor de bătătură și tipul de legătură nu au înregistrat efecte semnificative.

For this purpose, 35 different fabrics were woven with acrylic warp and acrylic, cotton, PES, viscose, acrylic/cotton, acrylic/viscose and acrylic/PES weft yarns, with three different weft densities and plain, twill and satin weaves. Analysis of results showed that the effect of yarn material and weft density on thermal resistance was not observed. It was seen that weave type had an effect on thermal resistance, thermal absorbtivity and air permeability of the fabrics. Air permeability values of fabrics woven with plain weave were lower than those of satin and twill weaves. The air permeability decreased when weft density was increased. According to statistical evaluation, yarn type or yarn material had significant effect and weft density and weave had no significant effect on water vapour resistance.
In this study, the effects of weft yarn count, weft density and weave type on the air and water vapor permeability properties of 100% acrylic woven fabrics were examined and evaluated statistically. Fabrics were produced with two different weft yarn counts (Ne 20/1 and Ne 16/1), three different weft densities (13, 15 and 17 thread/cm) and three different weave types (plain, twill and satin).
