  • The Membrane structure has a number of problems in the application of a fireproof code based on general buildings codes. Thus, the fireproof code of membrane structure is necessary to activate the construction of the membrane structure. Because it requires a systematic classification of fire retardant and flame proof performance of membrane material. Fire retardant and flame proof tests are conducted on membrane materials mostly used in current construction to propose the fire and flame retardant performance criteria of membrane materials. Fire and flame retardant tests results, PTFE membrane material with the glass fiber fabric have a limit-combustible performance. PVDF membrane material with the polyester fabric does not ensure the fire retardant performance, but this membrane material has the flame retardant performance of a thick fabric. Also, ETFE does not ensure the fire retardant performance, but this membrane material has the flame retardant of a thin fabric.

  • This study examines the isolation-heat performance of fire proof fabric that is equipped over ceiling board in order to secure the capability of arresting the spread of a fire at roof 'Jucsim' structure of Wooden Cultural Properties. For this examination, I conduct experiments with the model and compare two construction methods of fire proof fabric, or flat-type, folding-type. The experiments show the following results. In case of installing the fire proof fabric in flat-type, when the temperature under the ceiling board is $750^{\circ}C$, the temperatures over the ceiling board is $50^{\circ}C$; the difference is $700^{\circ}C$. Compared with the case of removing fire proof fabric, the temperature over the ceiling board is lower by approximately $580^{\circ}C{\sim}600^{\circ}C$. Therefore it can be said that the construction of fire proof fabric enhances the isolation-heat performance. In case of installing the fire proof fabric in folding-type, when the temperature under the ceiling board is $600^{\circ}C$, the temperatures over the ceiling board is $65^{\circ}C$; the difference is approximately $530^{\circ}C$. Thus its isolation-heat performance is a little inferior to the flat-type equipment.

  • The combustion characteristics of roof 'Jucsim' structure was analysed using real scale fire test on wooden structure heritage building. the fire test model was made to consider roof timberling internal structure for a Sunglemun. Structure of test body layed lime, soil, 'Jucsin' and ceiling board excepting roof tile to find heat propagation process by setting thermocouples. The first test to find fire growth and heat propagation process in the part of ceiling. The second test organized to find the efficiency of fire proof paint between ceiling board and inside of Jucsim structure. The third test try to get the performance level of fire proof fabric with the same manner. The result showed from the test proof the heavy smoke exposure with limited effect of fire proof paint however, reliable fire resistance effect showed in case of fire proof fabric.

  • Metal ducts for transporting air conditioning and heating inside ships have recently been replaced by cloth ducts that have the advantage of delivering air evenly to the compartments, with excellent noise reduction in major compartments, such as combat command rooms, steering rooms, and sound detector cabins. Since the performance requirements of fabric ducts for vessels are strict, and the entire length of the ducts was imported from Korea, the government wants to create economic effects through localization of fabric ducts. Air permeability and fire prevention performance tests verified the applicability to naval vessels of fabric ducts developed by Hyundai Heavy Industries and HiDact, and performance requirements presented in the POS were verified. As a result of the tests, the fabric ducts met the requirements for air permeability and fireproof performance.

  • The purpose of this study was to examine the outdoor sportswear purchase behavior, outdoorwear sportswear brand preference, functional fabric awareness, and benefits sought. The research was performed through in-depth interview during February to March 2011. Data were collected from 10 consumers who had purchased outdoor sportswear and experienced camping in 6 months. First, the results from study showed that functionality/comfortability, design, color, and brand name were important factors in selecting outdoor sportswear. Offline stores were the main place to purchase, however, internet shopping mall and portal online community were another shopping channel as well. Second, respondents preferred imported outdoor sportswear brand to national brand. According to the study, the respondents trusted the imported outdoor sportswear quality based on the brand name, value, and brand history more than national brand. Third, consumers who had low functional fabric awareness were more likely to evaluate apparel products based on the brand name. Knowledge levels for textile functions were high in elastic, UV protection, air permeable, and antibacterial properties. The essential features for camping were water absorbing and quick dry, water resistance, wind proof, UV protection, and fire retardant properties. Finally the results showed that there were two sportswear benefit soughts: functionality and status ostentation.

  • This study is designed to understand current wearing conditions of air force mechanic parkas and evaluate their functionality by examining the wearing conditions and wearers' subjective assessment. By doing so, it also intends to identify issues that require improvements; and to provide basic data for future development of air force mechanic parkas. A survey was conducted as a study methodology, and the collected 1,628 questionnaires were analyzed. Findings of this study are as follows. 1. In the usability assessment, it was found that visibility of body sides was needed to be enhanced since reflective tapes were attached only to the front and back of the body; pockets were too big, but not convenient to keep mechanic tools; the design of hiding hood was not suitable for water-proof clothing; and a new design of size-controllable hood was called for since the hood blocked eye sight. With respect to the fabric, dissatisfaction was identified with durability, cold-proof and fire-proof features. 2. In the mobility assessment, respondents showed low satisfaction with collar heights and neck girths. Mobility score was over moderate level on average, except the parka length that obstructs wearers' movement, and neck and collar size. 3. In the wearability assessment, respondents presented moderate satisfaction with pleasantness, weight, pressure and dampness. However, insulation was found unsatisfactory. Based on the result, this study proposed improvement plans on design, pattern and fabric; and is expected to serve as basic data for developing more effective and functional air force mechanic parkas.
