최재우,장봉식,Choi, Jae-Woo,Jang, Boung-Sik 한국산업융합학회 2006 한국산업융합학회 논문집 Vol.9 No.4
The tensile properties of Poly(trimethylene terephthalate, PTT) $1{\times}1Rib$ knitted fabrics were experimentally studies, and the specimens has $1{\times}1$ rib stitched structure which are weft knitted fabrics with various lengths of loop. The $1{\times}1$ rib weft knitted fabric showed larger tensile linearity, tensile energy and tensile resilience in the direction of courses. The tensile properties increased with increasing the loop density in all directions, and perfectly increased with the course directions than the wale directions.
Polytrimethylene terephthalate(PTT) 가연사의 수축거동에 관한 연구
최재우,장봉식 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.4
Shrinkage properties of drawn textured Poly(trimethylene terephthalate, P1"1') yarn, which has been developed recently, were investigated to provide fundamental information for the textile industry. Shrinkage ratio characteristics on PTT yarn with six different count were investigated with tension, dry and wet thermal temperature. In non-tension, the shrinkage ratio were increased to increasing temperature at dry and wet thermal treatment, and in tension, the shrinkage ratio were increased to increasing tension at dry and wet thermal treatment.
Polylactic acid(PLA) 위편성물의 수축특성과 형태안정성에 관한 연구
최재우(Jae-Woo Choi),장봉식(Bong-Sik Jang),이은우(Eun-Woo Lee) 한국산업융합학회 2013 한국산업융합학회 논문집 Vol.16 No.2
Aim of this study is to investigate the dimensional and shrinkage characteristics of the weft knitted fabrics with Polylactic acid(PLA) knitted yarn. This PLA knitted yarn was made of the biodegradability fiber. The structure of weft knitted fabrics that was utilized for this study is the plain stitch, which is the most basic structure among all weft knitted fabrics. As the stitch length is shorter, the stitch density, courses density, and wales density are more increasing. The stitch density increased as pre-treatment process and dyeing process progressed. On the contrary, the heat setting process made it decreasing. The MR(Machine Relaxation) and DR(Dry Relaxation) standard area shrinkage were increasing as wet process progressed and as the stitch lengths are long.
Bamboo사 평 편조직 위편성물의 형태안정성에 관한 연구
최재우(Jae-Woo Choi),장봉식(Bong-Sik Jang),이은우(Eun-Woo Lee),김동엽(Dong-Yeub Kim) 한국산업융합학회 2012 한국산업융합학회 논문집 Vol.15 No.3
Aim of this study is to investigate the dimensional characteristics of the weft knitted fabrics with Bamboo knitted yarn. This Bamboo knitted yarn was made of the biodegradability fiber. The structure of weft knitted fabrics that was utilized for this study is the plain stitch, which is the most basic structure among all weft knitted fabrics. The loop density, courses density, and wales density are more increased as the loop length is shorter. The loop density increased as pre-treatment process and dyeing process progressed after dry treatment process, and on the contrary, the heat setting process made it decreasing. After the dyeing process proceed, the loop density and the course density were displayed the highest values. When the knitted fabrics were fully relaxed, the loop density was 2000/in², the courses density was 52/in, the wales density was 39/in.
