Investigation of the Characteristics of Elasticised Woven Fabric by Using PBT Filament Yarns

Abstract

Owing to growing demand for comfortable clothes, elastane filament yarns are being used in fabrics for several garments. In this study, core spun yarns were produced with cotton fibres and PBT/elastane filament yarns (cotton as sheath material, PBT yarn and elastane as core yarns). Twill woven (1/3 Z) fabrics were produced by using core spun yarns (30 tex) and cotton yarns (30 tex) as weft, and 100% cotton yarn (59 tex) as warp yarns. The fabrics consisting of PBT were washed at 100°C for 30 minutes to gain the elasticity. The woven fabrics’ weight, thickness, elongation, permanent elongation, dimensional stability, air permeability, thermal conductivity, thermal absorptivity characteristics were tested and statistically evaluated. According to the results, the fabrics containing PBT and elastane filaments had similar elongation and shrinkage values. PBT filament yarns have a great potential to produce lightweight elastic fabrics.

Functionalization of Woven Fabrics with PBT Yarns

“…Six fabric samples were woven on Sulzer rapier weaving machine, with the same 100% cotton warp (59 tex) and different wefts (PBT/Co core yarn, Elastane/Co core yarn, PBT filament: cotton yarn in sequence 1:1 and 100% cotton yarn). All samples were woven with the same on-loom settings: 12 ends/cm, 28 picks/cm, and in twill 1/3 Z. Woven fabrics containing PBT yarns were treated in boiling water for 30 min to impart elasticity [ 16 ]. The fabric characteristics are given in Appendix A , Table A1 .…”

“…In the study [ 16 ] the following properties of woven samples were investigated: physical properties (mass per unit area SIST EN 12127:1999, thickness of textiles SIST EN ISO 5084:1999), the woven fabric resistance to stretch (TSE-TS 6071), air permeability (EN ISO 9237:1995), thermal and water-vapor resistance under steady-state conditions ((Alambeta, Sensora Co., Liberec, Czech Republic), ISO 11092:2014), dimensional stability after thermal treatment (ISO 3759:2011). Results of resistance to stretch, dimensional stability and thermal comfort properties, weight, and thickness values of the fabric samples are given in Appendix A , Table A2 and Table A3 .…”

“…In the study [ 27 ], the influence of Lycra and PBT in woven structure on UV properties of fabrics is discussed. The fabric samples were produced under the same settings as in the study mentioned above [ 16 ], with the exception that all weft yarns (PBT/Co core yarn, Elastane/Co core yarn, PBT filament: cotton yarn in sequence 1:1 and 100% cotton yarn) were thinner, namely 24.5 tex.…”

“…All these features distinguish PBT, the elastic but nonelastomeric yarn, as suitable for use in knitted fabrics [ 12 , 13 ] and woven fabrics [ 5 , 6 , 14 , 15 , 16 ], for blending with all natural or synthetic yarns in various yarn structure forms (filament, core-spun yarn, dual-core yarn) [ 14 , 16 , 17 , 18 ]. PBT is therefore particularly suitable for sportswear, underwear and outerwear, and also for textiles in car interiors or for floor coverings.…”

“…The overall study had the primary objective to find out by how much the stretchability of the manufactured fabrics improves after thermal treatment and how other properties are affected. The research was divided into three thematic sections according to the preliminary investigations, with which we tried to define a specific framework for further experiments [ 6 , 15 , 16 , 27 ].…”
