Abstract:To investigate the effect of fashion style on ease distributed features in different body parts and orientations, three female shirts with same size specifications but different silhouettes are designed. Seven female participants whose body shape are similar to Chinese garment size standard are scanned by three dimensional human body scanner both with and without experimental shirts. The ease distribution of three shirts is measured and analysed by using Geomagic Qualify software. The results show that ease distribution of most body parts can be influenced by garment styles except the upper back and chest. Ease allowance are not evenly distributed in different orientations of body parts, it tends to be lager at lateral body than at medial. This knowledge can be applied to pattern design for better fitness. | |||

Abstract:Objective and quantitative evaluation of clothing thermal protective properties should be based on the simulation of human in actual thermal environment as realistic as possible. In this paper, by using a new type of flame manikin which can rotate and make different postures, the dynamic scene that a firefighter wearing fire protective ensembles doing rescue job in the flash fire was simulated. According to the skin burn prediction result, the total burn percent suffered by the manikin was 7.76%, of which the 2nd degree burn and the 3rd degree burn account for 5.12% and 2.64% respectively. This indicates that the firefighter ensembles have relative good thermal protective property. It can provide enough protection for the firefighter in 8s dynamic exposure while more protection should be added to the head. | |||

Abstract:Combustion characters such as afterflame, color fading, thermal shrinkage, carbonization, smoke production provide a comprehensive reflection of the garment performance as a whole. Based on the flame manikin testing system, six kinds of garments which can be divided into two groups (PSA clothing and aramid clothing) were used for combustion experiments, and the combustion characters were analyzed under the same exposure conditions. Results show that the after flame time of PSA clothing was longer than that of aramid clothing, showing poorer flame resistant performance. Large areas of color fading happened to most of the test samples. The average thermal shrinkage of the PSA clothing is greater than the aramid clothing with similar weight and weaving structure. Clothing with larger fabric gram weight and thickness tends to have smaller shrinkage degree. The carbonization degree of PSA clothing was more serious than that of aramid clothing. Smoke amount may relate to the dying and finfish of fabric. | |||

Abstract:This paper seeks to predict the heat transfer properties of the numerical manikin. It also aims to establish a simplified clothing model based on computational fluid dynamics (CFD) to predict the temperature in air layers between thermal manikin and clothing under different environments. The field experiments of nude or clothed thermal manikin were conducted in a climatic chamber. The CFD method was employed to build a nude or clothed numerical manikin to simulate the field experiment. The distribution of temperature and the velocity field around the nude human body and heat transfer coefficients were simulated in the optimized numerical climate chamber with a temperature of 20oC and velocity of 0.05m/s. The temperature in air layers entrapped in clothing dressed on the torso of manikin was also predicted under the same environmental condition. The CFD results showed good agreement with that of the nude or the dressed thermal manikin experiment. It demonstrated that CFD could properly predict the heat transfer properties of indoor human and temperature distribution in the air layer between human body and clothing. | |||
