  • This study surveys the tension differences between Korean domestic and foreign looms and analyses fabric mechanical properties due to warp and weft tension differences using KES-FB system. Paper is divided by two parts. In this 1st paper, fabric is designed as 5 harness satin weave using 75d/36f warp and 100d/192f weft polyester filaments, and is woven by $Omega^\circledR$ rapier loom by Textec Co.Ltd and Picanol$-GTX^\circledR$ rapier loom by Picanol Co.Ltd respectively. These grey fabrics are processed on the same dyeing and finishing processes. Weavability is also analysed by measuring warp tension variation according to the warp position, the relationship between shed amount and the warp tension on one fixed heald frame is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.

  • The optimum fabric design plan is recently needed with the relevant fabric shrinkage in dyeing and finishing processes for the various sensible fabrics for garment. For responding this need, the difference of fabric design plan such as fabric density, yarn count and finishing shrinkage has to be surveyed with weaving looms such as water jet, air-jet and rapier looms, and also has to be analysed with weave pattern such as plain, twill and satin according to the fabric manufacturers. Therefore, in this study, 420 polyester weave pattern sheets are collected from 5 fabric manufacturers, and the weave density coefficients of these fabrics are calculated using yarn count, fabric density and 1 repeat weave pattern. These weave density coefficients are analysed according to the fabric manufacturers, weaving looms and various weave patterns. And also the weave density coefficients of 420 polyester fabrics are analysed with finishing shrinkage according to the fabric manufacturers and various weave patterns such as plain, twill and satin fabrics.

  • 레피어 직기는 1,000rpm 이상의 워터제트와 에어제트 직기의 생산성에 미치지는 못하지만 제직 범위가 넓고 다양한 색사 사용이 가능하다는 장점으로 인해 고급직물을 생산하기 위해 오늘날에도 폭넓게 사용되고 있다. 현재는 외국 선진국뿐만 아니라 국내에서도 레피어직기는 제트직기와 더불어 주력개발기종 중의 하나이다. 근래 레피어직기의 개발방향은 고속화에 주력하고 있다. 레피어를 고속화하기 위한 시도는 위입구동부, 바디침기구, 개구부, 송출부 및 권취부 등 전반적으로 검토되어야 하지만 본 연구에서는 바디침기구의 고속화를 위해 바디침기구의 구동원이 되는 구동캠의 성능향상에 목적을 두고 수행되었다.

  • This paper proposes a novel knowledge extraction system, TAKES (Two-step Approach for Knowledge Extraction System), which integrates advanced techniques from Information Retrieval (IR), Information Extraction (IE), and Natural Language Processing (NLP). In particular, TAKES adopts a novel keyphrase extraction-based query expansion technique to collect promising documents. It also uses a Conditional Random Field-based machine learning technique to extract important biological entities and relations. TAKES is applied to biological knowledge extraction, particularly retrieving promising documents that contain Protein-Protein Interaction (PPI) and extracting PPI pairs. TAKES consists of two major components: DocSpotter, which is used to query and retrieve promising documents for extraction, and a Conditional Random Field (CRF)-based entity extraction component known as FCRF. The present paper investigated research problems addressing the issues with a knowledge extraction system and conducted a series of experiments to test our hypotheses. The findings from the experiments are as follows: First, the author verified, using three different test collections to measure the performance of our query expansion technique, that DocSpotter is robust and highly accurate when compared to Okapi BM25 and SLIPPER. Second, the author verified that our relation extraction algorithm, FCRF, is highly accurate in terms of F-Measure compared to four other competitive extraction algorithms: Support Vector Machine, Maximum Entropy, Single POS HMM, and Rapier.

  • This paper surveys the fabric weavability and machine efficiency in the various weaving looms such as Projectile, Rapiers, and Air-jet. Used projectile loom was Sulzer-PU, and FAST-R, THEMA-11E, and Picanol-GTX were used for Rapier looms, as the Air-Jet looms, Picanol PAT and OMNI types were used. Using these looms, 5 harness worsted satin fabrics were woven for surveying the fabric weavability and machine efficiency. Warp yam count of fabric is 1/40Nm, Sirofil, and filling is 1/30 Nm, worsted. End breaks of warp and filling directions for the various types of looms are measured and discussed with the mechanism of each loom. Warp and filling yam tensions are also measured and analysed with open width of shedding motion of each weaving machine. And various warp yam tensions with open width of shedding are measured and analysed according to the warp yam in various heald frame. These results fire also discussed with temples such as bar and ring. Warp yam tensions at the various positions on the fabric with various looms are measured and discussed with fabric mechanical properties such as tensile, bending, shear and surface.
