夏季服用织物动态热湿舒适性的影响因素研究

利用自制的织物动态热湿性能测试仪测定了不同透气性和不同原料的夏季服用织物在皮肤干燥-出汗-蒸发-干燥的过程中的皮肤热损失、微气候区温湿度变化的情况,研究了影响夏季服用织物动态热湿舒适性的因素,指出在外界风速较大或织物的透气量较大时,汗液蒸发是通过紊流扩散进行,由于汗液的快速蒸发,可能使人体产生冷感,此时不同织物的微气候区温湿度差别很小,当外界风速小或织物的透气性小时,汗液的蒸发通过分子扩散进行,此时微气候区的湿度主要受织物吸湿能力的影响,吸湿能力较强时湿度低,纯涤织物在出汗后,由于微气候区湿度较高,将使人产生闷热感,在出汗结束后降温较多可能产生冷感,不宜作为夏季服用织物,纯毛织物因吸湿放热多在出汗初期升温较高,不利于散热,夏季以穿着纯棉、涤棉、毛涤混纺织物的服装为宜.     

Study on the Factors to Influence Dynamic Heat - moisture Comfort of Summer Clothing Fabrics

In this paper, the factors to influence the dynamic heat - moisture comfort of summer clothing fabrics have been studied. It is pointed out that, when the wind speed outside is high, or the air permeability is very good, the sweat of human body will evaporate mainly through turbulent diffusion. Because of the rapid sweat evaporation, human body will feel cold, and then, the difference in temperature and humidity of the micro - climatic section will be very slight. On the contrary, when the wind speed outside is slow or the air permeability is unsatisfactory, the sweat of human body will evaporate mainly through molecular diffusion, and in this case, the humidity of the micro - climatic section will be depended on the hygroscopicity of the fabric, that' s to say, the better the hygroscopicity, the lower the humidity. It is difficult for pure wool fabric to loss heat because of its giving out much heat during the course of moisture - absorption in the initial stages of sweating. For pure polyester fabric,

IN RELATION TO CLOTHING COMFORT DYNAMIC MOISTURE TRANSFER THROUGH FABRICS

A sweating apparatus has been developed to permit simultaneous measurement for fabric temperature change and relative humidity change at outer still air layer of fabrics. In this paper, we compared the temperature and relative humidity changes for silk fabrics with polyester fabrics and got GM(1,P) relation models respectively between maximum fabric temperature change, maximum relative humidity change at outer still air layer and relative fabric character parameters. Furthermore, by comparing the objective experiments with subjective wear trials, it is found that the amounts of the change rate of fabric temperature and relative humidity at outer still layer are the most important factors which influence clothing comfort in dynamic moisture transfer condition. The more the changes of temperature and R.H., the more the mugginess and the thermal sensation.

Moisture Absorption, Mass Loss and Evaporative Resistance of Clothing in Transient Condition

The water vapour resistance of clothing ensembles is not as commonly determined as dry thermal insulation. The measurement techniques are more complicated and the measurement values differ among laboratories. Due to complicated moisture transfer process through clothing ensemble, the moisture absorbed and evaporated varies in transient and steady state phases depending on properties, thickness of clothing, and environmental conditions. The purpose of this study was to measure moisture gain inside hygroscopic underwear, and hydrophobic and permeable outer wear as a function of time, to investigate mass loss from ＂skin＂ as well as from the manikin, to quantify evaporative heat loss and total heat loss from the manikin, and to determine water vaponr resistance of clothing. Manikin Tore was used by wearing wet ＂skin＂ to simulate sweating condition. Moisture content in the inner garment gain shows an exponential relation against time. Moisture in the outer permeable layer shows little gain. On the contrary, mass loss directly from the wet skin decreases exponentially. The mass loss from the manikin is relatively stable throughout three test phases. The evaporative heat loss is about 2/3 of the total heat loss from the sweating manikin. While measuring the evaporative resistance of clothing ensembles with hygroscopic inner garment and permeable outer garment, unlike to measure ensembles with impermeable outer layer, one hour measurement time is enough to get relatively stable results. The variation between the 1^rt hour and the 3^nd hour is less than 5%. The length of transient period and measurement time is dependent on the permeability, thickness of clothing ensembles and environmental conditions.

Fabrication of cotton nano-powder and its textile application

A combination of chemical and mechanical treatment of cotton produced cotton powder （fibrils） with a mean diameter of 97 nm is analyzed by Laser Particle Size Analyzer. Transmission Electron Micro- scope （TEM） study showed that the diameter of the fibrils was about 10--30 nm and the length was from 70nm to over 400 nm. The powder was then coated onto fabrics （100% polyester fabric, 100% wool fabric and 100% cotton fabric）. Scanning Electron Microscope （SEM） study showed that cotton fibrils were adhered to the surface of treated fabrics （fibers）. The ultraviolet protection factor （UPF） value （AS/NZS 4399： 1996） for cotton fabrics increased about 20% after the treatment. This implies that the treated samples give a better protection from UV light. The moisture management test （MMT） of the fabrics such as wetting time at bottom, top maximum absorption rate, bottom maximum absorption rate, bottom maximum wetted radius and bottom spreading speed, et ah, showed that there were significant changes after the treatment. These changes gave better moisture management ability to the treated fabrics and thus made the fabric more comfortable. However, Wide-angle X-ray Diffraction and Fourie Transform Infrared Spectroscopy analysis proved that supermolecular structure and chemical struc- ture of treated fabrics were the same as the original fabrics. Other properties of the treated fabric such as thermal conductivity, wrinkle recovery, hand, et al., did not change. This implied that the basic func- tion of the treated fabrics for the clothing industry was the same as untreated fabrics. This study is a foundation for further researches on textile application.
