moisture permeability
1.Quantitative analysis of each factor on the moisture permeability was conducted, and it revealed that they were in such an order: ambient temperature>pressure>relative humidity>time of moisture transmittance.
2.The second layer consists of a honeycomb-like structure. This porous layer achieves moisture permeability and resistance to water penetration.
3.The Austrian machinery producer SML in Lenzing has developed and optimized a line as well as a process, whereby waterproof but breathable plastic films, simply called “breathable films”, with a wide range of moisture permeability, can be produced.
4.Compared with like products UC coat 2000 of UCB company(Belgium) and Entrant GⅡ-TX of Toray company(Japan),the water pressure resistance and moisture permeability of the synthesized polyurethane coating agent are ascendant.
5.The wearabilities of two types of leather and four types of suedine made of PA6 micro fiber were tested, compared and analysed through microconfiguration analysis, such as breathability, moisture permeability, drape, softness, tensile strength, tear strength, bursting strength and rubbing fasmes.
7.It reveals that insame condition of alkali treatment, hydroscopic property、 conductivity moisture、moistur permeability and permeability of BPL were better thanPL , the key lay in quantity、size and distribution of microhole.
8.The results showed that temperature of freezing storage had influences on the zein films, which led to the changes of mechanical properties, equilibrium moisture content (EMC), water vapor permeability (WVP).
9.It has been proved: the permeability of light-weight worsted fabrics is not only affected by the moisture absorption, twist, the fineness of yarn, but also by the weave, the count of fabrics greatly, while the permeability is affected by thickness slightly.
10.The research for soil permeability and surface runoff in Huangjia-Er- cha small watershed in Xiji county, Ningxia, was done by means of arti- ficial precipitation and runoff-plot testing method,which showed that pri- mary factors affecting soil permeability are land utilization, slop, soil moisture, total porosity of soil and rain intensity.
