Impact of Weft Yarn Density and Core-yarn Fibre Composition on Tensile Properties, Abrasion Resistance and Air Permeability of Denim Fabrics

Abstract

Characteristics and serviceability of denim fabrics have undergone major changes. Nowadays denim is commonly used for casual wear. Durability and comfort are important parameters for consumers when choosing a denim garment. Therefore, in this study, abrasion resistance, tear and tensile properties of core–spun yarns and air permeability of denim fabrics with different weft yarns per centimetre and fibre content were analysed. The test results showed that weft yarns per centimetre influences fabric air permeability negatively but abrasion resistance increases. Higher weft yarns per centimetre influences fabric air permeability negatively but abrasion resistance increases. Polyester, elastane, modal, viscose and Lycra T400 were used in the core of weft yarn to analyse the impact of those fibres on the durability and comfort properties. Elastane is used to add stretchability to the fabric, which provides comfort to the wearer. The higher the elastomeric fibre content in the fabric, the greater is its elasticity; however, the tensile properties of the woven fabric decrease. The tear strength of the fabric was increased by the presence of the polyester fibre in the core.

Towards Sustainable Jeans Production: Experimental Evaluation of a Denim Fabric to Abrasion Resistance by Dry Fabric-to-Fabric Rubbing

“…The standard abradant fabric is made of wool and specimen movement is a repeating Lissajous figure, which allows avoiding the effect of sample orientation. Despite the numerous research related to the abrasion resistance of denim fabrics that have been made, they are focused mainly on the yarn type, composition and structure parameters [5,6,7,8,9,10], weave type [9], yarn spinning technology [10], weaving technology [11,12] and fabric finishing [10,13,14,15,16]. There is a lack of information on denim-to-denim abrasion studies.…”

Optimisation of laser fading process in denim trousers: An industrial scale approach

“…When the literature is examined, it is seen that there are many articles on the effect of laser treatment on various properties of denim fabrics and the fading effects obtained by laser. [1][2][3][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Laser treatment is normally applied as a single passage. However, in cases where high fading degrees are required in industrial-scale production, fabric strength decreases significantly when high doses of laser are applied at a time on sensitive fabrics.…”

“…However, in practice, high strength losses and even tears may occur in the trousers as a result of incorrect or excessive laser application. When the literature is examined, it is seen that there are many articles on the effect of laser treatment on various properties of denim fabrics and the fading effects obtained by laser 1–3,5–18 . Laser treatment is normally applied as a single passage.…”
