A methacrylate monomer having phospholipid polar group and cell membrane structure is known as highly biocompatible. Based on these properties, new biocompatible multi-functional textile finishing agent was developed using phospolipid copolymer. 2-Methacryloyloxyethyl phosphorylcholine (MPCE) was synthesized using 2-hydroxyethyl methacrylate (HEMA), 2-chloro-2-oxo-1,3,2-dioxaphospholane (COP) and triethylamine (TEA), and then polymerized to prepare MPCE copolymer by radical polymerization using azobisisobutyronitrile(AIBN). The structures of MPCE was characterized by FT-IR and 1H NMR and will be evaluated as textile finishing agent in further study.

The purpose of this study is to develop a textile knowledge checklist and to analyze university students' textile recognition. After analyzing reliability, difficulty, and discrimination of questions, we developed a standardized tool to measure textile knowledge. The tool has 72 checklist questions, which can be divided into 4 parts: basic property, comfort, management, and finishing. The level of university students' textile knowledge was 68.91 %. The level of basic property was 75.56%, comfort 70.83%, management 64.5% and finishing 64.74%. The recognition of management and finishing was lower than that of basic property and comfort. There existed a significant difference in the textile knowledge by their gender, major, and school year. To elaborate, females, clothing and textile major students, and juniors and seniors showed higher level of textile knowledge. It seemed that comfort was more professional item than management in textile knowledge.

Andongpo, 100% Korean hemp fabric was treated with the glyoxale resin type finishing agent and/or the soluble urethane type finishing agent to determine the optimum process condition of the crease resistant finish and the crease recovery of treated sample fabrics was evaluated for the study. The treatment conditions for the study were 6 conditions, such as, A-1~A-6, in which A-1 was the condition of treatment glyoxale resin type finishing agent only and A-2~A-6 were the condition of treatment both glyoxale resin type finishing agent and soluble urethane type finishing agent. Among the 6 conditions, the crease recovery of the sample treated with A-4 condition was $148^{\circ}$(angle of recovery method) and grade 3.2(appearance method) and so, these samples showed the excellent crease recovery. From the result, 15g/l of the catalyst conc., 50g/l of the glyoxale resin type finishing agent cone., and 40g/l of the softner were the optimum treatment condition for the crease resistant finish of the andongpo.

The purposes of this study are to analyze shopmasters' knowledge of apparel merchandise and textile recognition and to investigate the effects of demographic variables on them. Shopmasters' knowledge of apparel merchandise was analyzed on a factor basis. Four factors of apparel merchandise were fashion property, material property, function property and management property. The textile knowledge level of shopmasters was 72.44%. Considering each part of textile knowledge, basic property was 74.69%, comfort 72.17%, management 68.36% and finishing 77.33%. The level of recognition in finishing area was the highest and the level of recognition in management area was the lowest. There were significant differences in the textile knowledge by gender and working period. Female's textile knowledge level was higher. The longer the working period is, the higher the level of textile knowledge is. Shopmasters recognized the finishing area better than university students did. But both of the groups didn't recognize the management area well.

The azo red pigments for textile printing containing amino-N-substituted benzamide derivatives as diazo components and 2-hydroxy-3-naphthoyl derivatives as coupling components were prepared. They have been printed on cotton, and the fastness, such as light, washing, dry cleaning, rubbing and heat stability was estimated. The new azo red pigments were valuable colorants in case of textile printing.

The aim of this study is to investigate the general status, operating status, and the satisfaction level of participating textile-clothing companies involved in the Work and Learning Dual System in Daegu. The general status and operating status of the participating companies are as follows. As of March 2016, 34 of the 43 companies in Daegu participated in this survey, and they were divided into three areas of textile: weaving, dyeing & finishing, and apparel manufacturing. The breakdown is as follows: 14 dyeing & finishing companies (41.2%), 13 apparel manufacturing companies (38.2%), and 7 textile weaving companies (23.6%). The results of the survey showed that 91.2% of the companies decided to participate in the system to cultivate their employees into experts in the field. The satisfaction rate of the theoretical education and training institutions was 3.88 out of 5 points. In particular, the satisfaction rate of the textile weaving companies was as high as 4.29, and the satisfaction level of the dyeing & finishing companies was higher than the average of 3.71. The overall satisfaction rate for the work-related paradigm was 3.97 out of 5 points. The results of this survey can be used to conclude that the Work and Learning Dual System is operating as it was intended to be by the government.

In this study, dye encapsulated microcapsules were produced by polyurethane prepolymer synthesis method using hexamethylene diisocyanate, ethylene glycol and methyl ethyl ketone. The study showed that the average size of microcapsules were $4.697{\mu}m$ in normal distribution. These microcapsules were induced red color by thermochromic fluoran red dye with showing color change as temperature. After the textile finishing of microcapsules, durability of microcapsules were checked as crocking times and lightfastness. The microcapsules were pressed at protrusion of textile weave in 10 crocking times which meant that the microcapsules not fallen off. Lightfastness was acceptable giving rating 4. It means that the polyurethane microcapsules not affect to light durability.

In this study, a study and interpretation of the spinning process in copolymerized aramid spinning was conducted. In order to proceed with the spinning process modeling and analysis, the spinning process was modeled through the physical property modeling of the spinning solution and the structural modeling of the spinneret, and structural stability and flow of the spinneret for this spinning were analyzed. After modeling the spinning solution and the spinneret in a virtual space, the pack pressure and flow rate when the spinning solution was discharged were simulated. Macroscopically, the structural stability of the spinneret was confirmed at the standard pack pressure (100 kg·f/cm²), and microscopically, the flow rate and pressure drop data of the spinning solution according to the L/D(Length (L)/Diameter (D)) value were analyzed. Based on the research and development of virtual engineering modeling and analysis, we present the possibility of changing the shape and mechanical properties of copolymer aramid fibers according to the spinning process.
