In this research, the dyeing properties of Lycopus lucidus Turcz on cotton and silk fabrics were evaluated to establish a scientific database of natural dyes. The optimum dyeing conditions were identified with K/S values depending on the dyeing concentration, temperature, time, and pH. For the optimum conditions, the color changes for different synthetic mordants were observed as L, a*, b* and H, V, C. The color fastness after dyeing and mordanting was also examined. Additionally, the antibiosis of Lycopus lucidus Turcz was examined. The results were as follows: For the cotton, the optimized dyeing conditions were 300% (o.w.f.), 50℃, 40 min., and pH 5. For the silk fabric, the conditions were 450% (o.w.f.), 70℃, 60 min., and pH 4. The K/S value of dyed cotton improved about 1.03-2.78 folds after mordanting. The fabric color was yellow in the absence of mordanting, while it was reddish yellow after post-mordanting with FFC. Although the color changed with the mordanting method and mordant, the overall hue was yellow. Thus, Lycopus lucidus Turcz appears to have the potential for use as a natural dyeing material for a yellow hue. The K/S value of the dyed silk fabric improved about 1.05-1.40 folds after mordanting. The fabric showed a reddish yellow color when pre-mordanted with Al and Cu. The washing and dry-cleaning fastness of the cotton and silk fabrics were at the 4-5 level. The light fastness of the cotton improved after mordanting; however, pre-mordanting was more effective than post-mordanting or the absence of mordanting. The dyed cotton, silk fabrics showed excellent antibiosis.

This develops a new and advanced S/S knitwear material made of linen/bamboo blended yarn. Linen/bamboo knitted fabrics were compared with linen/polyester knitted fabrics in terms of appearance as well as physical and comfort properties. Rib knitted fabrics were remarkably thicker than plain knitted fabrics. Knitted fabrics based on polyester yarns were heavier than those based on bamboo yarn. The porosity decreased in the following order: linen 100% > bamboo 100% > polyester 100%. The drape properties of bamboo 100% and linen/bamboo knitted fabrics were excellent. The pilling resistances of linen 100% and linen/bamboo knitted fabrics were excellent. The highest and lowest air permeability was observed in the case of linen/bamboo knitted fabrics and polyester 100% knitted fabrics, respectively. The instant cool-feeling was enhanced as the bamboo yarns were blended. The thermal conductivity of linen 100% knitted fabrics was the highest and the thermal conductivity of linen/bamboo knitted fabrics was higher than linen/polyester knitted fabrics. Bamboo 100% knitted fabrics showed a higher moisture regain than polyester 100% knitted fabrics. The results confirmed the superior appearance and comfort of a novel S/S knit wear material made of linen/bamboo knitted fabric.

Knitted fabric using acrylic/wool blended yarn (A/W) is increasingly used in the knit industry; subsequently, research on knitted fabric using A/W has increased. This study presents an scientific database from evaluating physical properties of 1×1 rib stitch using A/W. In this study, 1×1 rib stitch using A/W were made at various knitting tensions (dial no. 2-6) and the number (4-6) of ply yarn. The physical properties of 1×1 rib stitch using A/W were measured and analyzed. The density was in the range 5.5-6.4wales/cm and 4.0-5.6 courses/cm, respectively. The density increased when less plying yarns and more knitting tension were added during knitting. The thickness was in the range of 1.592-2.362 mm and the tensile strength was in the range 32.75-53.63Kgf/mm. The burst strength was in the range 107.8-139.2 N/cm2. Thickness, tensile strength, and burst strength increased as the number of ply yarn and the knitting tension increased. The elongation and the recovery extension rate were in the range 102.29-112.13% and 96.4-97.7%, respectively. The heat retention rate was in the range 59.3-65.1%. There was no difference of the elongation and the recovery extension rate and the heat retention rate by the knitting tension and the number of the ply yarn. The permeability was in the range 170.5-396.3 cm3/cm2/sec. Air permeability decreased as the number of ply yarn and the knitting tension increased. The pilling properties were excellent for all 1×1 rib stitches.

This study analyzed the effects of the knit stitch type, fiber composition, and yarn thickness on the mechanical properties of knitted fabric. The results were as follows: The course density was the highest in the case of the rib stitch. On the other hand, the wale density was the highest in the case of the float stitch. The thickness was the highest in the case of the rib stitch. The same results were obtained even for different fiber compositions and yarn thicknesses considered in this study. The burst strength of wool knit fabric was higher than that of NW knit fabric. The stiffness was the lowest in the case of the plain stitch. The same results were obtained even for different fiber compositions and yarn thicknesses. The pilling properties were excellent for all knit stitches, fiber composition, and yarn thicknesses as pilling degree : 5. The air permeability decreased in the following order : rib> plain> float stitch. The same results were obtained even for different fiber compositions and yarn thicknesses. The heat retention rate decreased in the following order : rib > float> plain stitch. The same results were obtained even for different fiber compositions and yarn thicknesses.
