Chitosan has a significant inhibitory effect on many bacteria and fungi such as Escherichia coli and Staphylococcus aureus both of which are the culprits of fruit spoilage [] According to investigation although the antibacterial ability of CMCS is not in direct proportion with its concentration CMCS showed the strongest ability of antibacterial at the appropriate concentration [ 29 ] The first uniaxial stretching from 0% to 1500% increased the air permeability from 1 23 cm 3 /cm 2 /s to 7 80 cm 3 /cm 2 /s and meanwhile decreased the breakthrough pressure from 4 98 mH 2 O to 1 55 mH 2 O Further stretching cycles had very small effect)

As a result temperature variation is increasing and the term is being prolonged frequency of high and low temperature is increasing by heat wave and severe cold Especially for reinforced concrete structure the corrosion of reinforcement has occurred by concrete crack due to temperature change and the durability of the structure that has decreased by concrete crack

The integration of thermoelectric (TE) device on fabrics is a challenge Instead of using adhesive tape to fix traditional filmlike TE devices onto the fabrics which saces the breathability of fabrics here we report a flexible TE fiber based on poly(3 4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/tellurium nanowires (Te NWs) composites which can be woven and integrated

In contrast to the highly porous sandstone the use of nanoparticles had a major effect on the breathability of marble which is a stone of low porosity A major improvement on vapour transport was noticed when nanoparticles were added to the protective coating the RVP% was reduced from 42 8 for marble coated by Silres to 16 8 for marble coated by Silres + nanoparticles

2019/8/28(c) Effect of maximum strain on heater's thermal stability during repeated stretching Photographic/IR thermal images and resistance changes during repeated (d) rolling and (e) folding tests Except for '(a)' strain was applied in the transverse (course) direction and input voltage of 5 V was used

evaluate the effect of using different concentration of sodium hydroxide (NaOH) solution in the purification process in order to identify differences on morphological structure physical and breathability properties of BC membranes 2 Materials

2019/11/13In recent years wearable and stretchable electronic devices have attracted great research interest and effort due to their promising applications in electronic skin wearable health monitoring human–machine interactions and so on However it still remains a great challenge to fabricate highly stretchable and wearable devices with excellent breathability mechanical robustness and

It is noted that in the present invention the temperature T1 of chill roller 28 and the temperature T2 of stretching roller 30 are significantly higher than in any previously disclosed MDO process In previous applications T 1 typically is from about 10 C to about 60 C and T

However this effect is mostly mitigated by their sateen weave maintaining more space between fibers and their crispness allowing more air to circulate under the sheets and around your body Keep in mind however that if you tend to eat or drink in bed you'll want to be extra careful around the Brooklinen Luxe Core — it took us 6 washes of the fitted sheet alone to remove a red wine

Temperature Regulation in Colored Infrared

Effective temperature regulation on wearables not only can improve human health and comfort but also hold great promise for energy savings Recent reports of infrared-transparent polyethylene textiles showed passive cooling effect by allowing the thermal radiation from the human body to pass through but they lacked the tunability in visible color

2 But it adds to the stiffness of laminate cost and reduces the breathability of the fabric 5 2 9 Smart breathable fabrics The Shape memory polymer restricts the loss of body warmth by stopping the transfer of vapor and heat at low temperature and at high

3 type and loading amount but also the stretching type has an enormous effect on breathability performance In addition the quality of porosity that is the amount of interconnecting pores was determined to play an important role in

2014/1/22If the cells are not platted on micropatterns uniaxial stretching results in cell elongation with most cells having a long axis aligned with the stretch axis It is then difficult to separate the effect of the long axis alignment and the effect of the stretch applied to the

2020/6/25Disposable medical protective clothing for 2019-nCoV mainly consists of stacked layers with nanopore films polymer coated nonwoven fabrics and melt-blown nonwoven fabrics against anti-microbial and anti-liquid penetration However such structures lack moisture permeability and breathability leading to an uncomfortable stuffy wearing experience Here we propose a novel

2018/9/1Meanwhile the stretching rate of 5–50 mm/min and the stretching temperature of 50–70 C were also carried out to test the influence of stretching rate and stretching temperature on the microporous structure of PLLA 2 3 Characterization 2 3 1 SEM

Such bonding effect making obtained compounding system more tolerant of multiple stretching and external force Owing to presence of collagen fibrils WPU/CO coatings exhibited superior temperature-adaptive water vapor permeability and hydrophilicity
