1. Development of Human-Clothing-Environment (HCE) Simulator and its applications
Combining the advantages of the skin model and the sweating manikin, a Human-Clothing-Environment (HCE) Simulator was developed in this study.
The simulator is a vertical skin model with two detachable chambers that can be utilized to measure heat and moisture transfer properties through textile materials under various environmental conditions as well as garment construction effects, such as layering and openness, and movement effects such as ventilation. It simulates real wearing situations effectively in terms of layering systems and various wearing conditions. Thus heat and moisture transfer properties and the material characteristics can be evaluated under dynamic environmental conditions. We could research on the followings by utilizing the HCE simulator.
o Verified reproducibility/accuracy and the advantageous characteristics over existing apparatuses from a series of experiments. Using polyethylene glycol treated nonwoven fabrics, the HCE simulator could verify thermal buffering characteristics of temperature adaptive materials under transient conditions.
o Examined the effects of the end use conditions on the performance of the functional textile materials were by using a microporous membrane laminated polyester fabric. Under arctic conditions, the breathability of the microporous membrane would be deteriorated due to condensation and/or freezing of moisture on the fabric surface.
o Analyzed coupled heat and moisture transfer through the clothing system under the various and transient conditions by simulating real wearing situations o Compared and analyzed the temperature adaptability and transient thermal efficiency between PCM and air inflation under the transient condition. Only profound amount of PCM could buffer a dramatic temperature drop but the effects lasted limited period of time while the still air layer systems provided lasting insulation,
o Verified and evaluated the versatile thermal insulation performance of SMA coil applied textile materials. Adequate temperature adaptability due to prompt and enough inflation under transient temperature were figured out.
o Examined the heat and moisture transfer profile and condensation in the multilayer cold weather clothing system to show the effects of layer array design. Distribution of the condensed water on each layer as well as vapor transfer of the whole system were influenced by the layer arrangement.
o Determined the performance of selected clothing systems under subzero conditions. Not only better vapor transfer property but also aropriate insulation is recommended in order to reduce the performance change of textile materials in cold conditions considering the condensation that occurs during exposure to subzero conditions.
o Predicted comfort properties of clothing systems with different hygroscopicity under the transient condition by using buffering indices.
o Developed temperature control index (T) and moisture management index (M) from the HCE simulator measurement and predicted wear comfort of shirts fabrics under sweat pulses at normal to warm condition.
2. Developent of High Functional Intelligent Textile Systems
Textile industry and customer needs are marching together toward development of high functional textiles and clothing. High functionality requires intelligent and dynamic propertiesof textile materials or garments. Various innovative materials have been used for the purpose of enhancing the thermo-physical performance such as insulation. Still air is the best insulator and very versatile depending on the manipulation on garments. When the still air is incorporated into a clothing system, it provides adjustable insulation to the garment and offers the broad range of climate control depending on the amount of the air. From one of the results from this project, we found that PCM buffered a dramatic temperature drop but the effects lasted limited period of time. To incorporate lasting insulation with spontaneous activation against temperature changes, two way shape memory effect (TWSME) was applied to a clothing system for both cold protection and heat protection. When these NiTi SMA extension springs are activated in garments, the air gaps between adjacent layers of clothing are increased. Consequently, incorporation of shape memory materials into garments confers greater versatility in the protection the garment provides against extremes of heat or cold.
o Development of a Versatile Insulating Jacket using Two-Way Shape Memory Alloy - Optimized thickness of air layer and operative temperatures were investigated and the dynamic insulation property of the jacket was evaluated using the HCE (Human-Clothing-Environment) Simulator and verified with garment wear trials with human subjects.
o Development of an Intelligent Turnout Gear for Dynamic Thermal Protection using Two-Way Shape Memory Alloy - A novel intelligent thermal protective turnout gear for firefighters that senses and reacts to environmental conditions without power supply problems were constructed. The SMA turnout gear provided many advantages: effective insulation of air, duration of the insulation, self-operating without any power supplying system, light weight, and comfort. The fire fighters preferred the newly developed SMA turnout gear to the conventional one.
3. Analysis of Liquid Moisture Transfer Properties and moisture comfort
Demand wettability and horizontal moisture absorption and desorption were assessed to analyze the mechanism of liquid water transfer into and through the textile materials.
o Commercially available high-absorption, fast-drying fabrics were compared in terms of their liquid moisture management performances. It was found out that the structural properties such as surface roughness, contact area, and thickness played significant role for moisture management. Even though the smooth surface (low SMD) had high absorption rate at the initial pickup, sensation of the dryness was worse than rough surface (high SMD) at the same water contents.
o Decisive moisture management factors to affect subjective moisture sensations were initial rate of absorption and total amount of water absorbed. o By applying a psychophysical method of constant stimuli method, moisture perception of shirt fabrics were investigated. Difference threshold (DL) of fabrics for moisture perception and the effect of fiber content and amount of water on the liquid water transport were analyzed by objective and subjective measurements. Although high performance PET fabric is made of engineered polyester fiber, its performance was not significantly different from the regular PET fabric, if the structure and thickness were well matched. It indicated that the effect of fiber shape on moisture management property was highly influenced by fabric construction and thickness. The level of sweat pulse had a great influence on subjective moisture discrimination associated with the moisture perception.
Therefore, the liquid water transport including both vertical and horizontal direction through the fabric should be considered to design optimum fabric for different activity levels. Moreover, the interaction between fiber type and shape and fabric construction should also be considered to improve the effectiveness of high performance fabric in practical use.
4. Measurement and Quantify the Fabric Hand Characteristics
o An image processing technique was employed to quantify the surface fiber, as an important factor for fabric hand, while the fiber aggregate length in 1 cm of fabric (lA) was determined as an influential predictor of a subjective feeling of fabric, such as softness and warmth.
o From the concept psycophysics, JND Oust Noticeable Differences) were adopted to explain and predict the fabric hand differences altered by finishing process.
o Textural features and perceptual structure of fabrics were classified to develope Texture Naming System (TNS). Texture Naming System (TNS) is to standardize and quantify the fabric texture by distributing in textural space such as color naming system (CNS) for color perception. TNS would be useful to recognize fabric tactile properties even without touching. For constructing TNS, we investigated basic textural space using the statistical techniques such as factor analysis, hierarchical cluster analysis, multidimensional scaling, non-linear artificial neural network system, and ANFIS (Adaptive Network based Fuzzy Inference System). Using ANFIS, we could position polyester fabrics in 3D spaces and showed its suitability for texture evaluation and positioning.
o The usefulness of a subjective evaluation of sensorial properties of textile materials is demonstrated, using the Quad analysis method. Quad analysis is known as an effective method of reducing the number of repeated comparisons, making it an efficient method in terms of testing time, while maintaining the advantages of the paired comparison test. It was proven that Quad analysis was an effective way to utilize and analyze the subjective evaluation of textile materials and subjective measurement is an important indicator for effects of textile processes.
o For on -line market for clothing, classification of texture of cotton fabrics was performed using Quad Analysis. Comparing on and off line image textures, objective information would be required for some fabrics, especially, napped, twill, pique, and broadcloth. The quad analysis enabled the ranking of the specimens in the order of roughness and surface roughness turned to be a proper predictor for classifying the cotton fabrics according to their roughness without touching. The results could provide reliable information for the internet market. by classifying and ranking of the fabrics.
