Development of woven stretch fabrics and analysis on handle,stretch, and pressure comfort

Twelve stretchable fabrics are woven in two sets with one set in 50^s and 60^s 100% cotton in warp and 40^s, 50^s, and 60^s cotton core spun lycra yarn in weft and another set with 2/75 and 2/120?Nm silk in warp with 40^s, 50^s, and 60^s cotton core spun lycra yarn in weft. Hundred percent cotton sari blouse materials commercially available in the market are also included for a comparative study of pressure distribution between cotton core spun lycra fabrics and cotton blouse materials. The influence of fabric specification on total hand value (THV), stretch properties, and pressure comfort is analyzed. The effects of body shape and fabric mechanical properties on garment pressure are also analyzed. The results indicated that the finer counts of cotton core spun lycra woven with cotton and silk to elasticize fabrics provided improved hand feel, stretch, and pressure comfort values. The average pressure value of the samples at the major pressure points with the cotton/cotton core spun lycra samples and silk/cotton core spun lycra samples is lower than 100% cotton samples’ fabric physical properties, stretch properties, mechanical properties, and THV significantly influenced the pressure distribution and comfort of garments.

Physical properties of ring,compact, and air vortex yarns made of PTT/wool/modal and wearing comfort of their knitted fabrics for high emotional garments

This study examined the physical properties of PTT/wool/modal yarns according to the yarn structure and the wearing comfort of their knitted fabrics for high emotional garments. For this purpose, the air-vortex, compact, and ring yarns and their knitted fabrics were prepared to analyze the wear comfort according to the yarn structure and the possibility of applications of the PTT/wool/modal blend fibers to air-vortex yarn. The wicking and drying rates of the air-vortex yarn knitted fabrics were superior to those of the ring and compact yarns fabrics, and the heat-keeping capability of the air-vortex yarn knitted fabric was higher than those of the ring and compact yarns fabrics due to the low thermal conductivity and maximum heat flow rate. In addition, the pilling of the air-vortex yarn knitted fabric was less than those of the ring and compact ones due to the air-vortex yarn structure with parallel fibers in the core part and the periodical and fasciated twists on the sheath part of the yarns. The tactile hand of the air-vortex yarn knitted fabric was harsher than those of the ring and compact yarns knitted fabrics because of the low extensibility and compressibility, and the high bending and shear rigidities.     

Analysis of mechanical and dimensional properties of the denim fabrics produced with double-core and core-spun weft yarns with different weft densities

Elastic structures are preferred for improving the elasticity and recovery properties of denim fabrics. With the intention of improving comfort during body movements in denim jeans, 10–35% elasticity is required. In this study, the effect of the composition of double-core (dual-core) and core-spun weft yarns and weft density on the mechanical properties of denim fabrics was investigated. For this purpose, different core materials were used in the production of elastic yarns. The sheath material was cotton for all yarn types. Yarn samples were spun with the same yarn count and twist coefficient. 100% cotton Ne 8/1 Ring slub warp yarns were used as warp yarn while double-core and core-spun yarns were used as weft yarns in weaving. The weaving process was performed with three different weft density values (16, 22, and 28 weft /cm) and the other production parameters were kept constant. Twill 3/1 woven fabrics were treated according to standard denim finishing procedures. After domestic washing processes, mechanical properties of the samples were tested and statistically evaluated.
