The water vapour permeability of clothing materials is a critical property for clothing systems that must maintain thermal equilibrium for the wearer. The evaporation of perspiration provides the means of cooling the human body. The perspiration should evaporate from the surface of the skin and pass as water vapour through the clothing, which must be permeable for comfort. The primary objectives in this study of the transfer through fabrics of water vapour are to measure this property in a quantitative manner appropriate to clothing systems and to provide an increased understanding of various types of fabric in water vapour transfer.

Today, China is drawing the attention of the entire world with rapid economic growth that commenced with the opening of its economy. The world recognizes the value of China as a massive market that will eventually lead the global economy in the future. This paper is devoted to basic research on Chinese apparel consumers and is intended to help apparel market developments in China. Its aim is to understand the distinct characteristics of China and to study general apparel designs and purchasing preferences necessary for the development of products that can meet the special needs of Chinese consumers. In addition it identified clothing behaviors to better understand the distinct characteristics of Chinese female college students preferences. The research showed that Chinese female college students preferred achromatic, dark blue, and red colors in decreasing order, and cotton and wool textiles. For style, they preferred designs that accentuated individuality. Also, comfort played an important role in purchasing. Behaviorally, they had strong interests in fashion but valued economic and pragmatic aspects when it came to purchasing, and were not much affected by the desire for identification. From research results, the paper concludes that there is a need for developing comfort-enhancing products for highly individual Chinese female college students, with designs uniquely preferred by them, and valueadded apparel products targeted for upper social levels.

The purpose of this study is to research the actual condition of working environment, working clothes and personal protective equipments on workers at a construction site in winter. The one to one interview by questionnaire was performed with 33 males and 2 females workers of a construction site in Daegu at $1.3^{\circ}C$ air temperature, 28% R.H., 4.7m/sec air velocity. The questionnaire consisted of 21 questions including 4 personal characteristics questions, 12 working environment/performance questions and 5 working clothes/personal protective equipments questions. It was modified from the original questionnaire developed by Finnish Institute Occupational Health. We found that physical stress of workers increased and the ability of performance decreased. The workers felt the coldest at hands/fingers, feet/toes and the face part of cheek, nose and ears. They rarely wore thermal clothing for winter and answered that the thermal gloves for winter did not provided enough warmth. Even if the workers recognized the necessity of personal protective equipments for their safety, they did not wear them for efficiency of working performance. These results will be useful elementary materials for development of working clothes and personal protective equipments from the viewpoint of improving both working performance and comfort.

Background: Thermophysiological comfort in a cold environment is mainly ensured by clothing. However, the thermal performance and protective abilities of textile fabrics may be sensitive to extreme environmental conditions. This article evaluated the thermal insulation properties of three technical textile assemblies and determined the influence of environmental parameters (temperature, humidity, and wind speed) on their insulation capacity. Methods: Thermal insulation capacity and air permeability of the assemblies were determined experimentally. A sweating-guarded hotplate apparatus, commonly called the "skin model," based on International Organization for Standardization (ISO) 11092 standard and simulating the heat transfer from the body surface to the environment through clothing material, was adopted for the thermal resistance measurements. Results: It was found that the assemblies lost about 85% of their thermal insulation with increasing wind speed from 0 to 16 km/h. Under certain conditions, values approaching 1 clo have been measured. On the other hand, the results showed that temperature variation in the range (-40℃, 30℃), as well as humidity ratio changes (5 g/kg, 20 g/kg), had a limited influence on the thermal insulation of the studied assemblies. Conclusion: The present study showed that the most important variable impacting the thermal performance and protective abilities of textile fabrics is the wind speed, a parameter not taken into account by ISO 11092.
