Basic Parameters

Cotton fabrics are very popular textile products to consumers due to their soft hand and comfortable wearing performance. However, the severe wrinkles on cotton fabrics will frequently happen after washing or wearing. As the growth of the market and demand of consumers, the sales of the steam ironing machine which can remove wrinkles to some extent is getting better. At present, the research is inadequate on the wrinkling mechanism during steam ironing. Therefore, in this paper, we aimed to investigate how cotton woven fabrics’ performance influences on the smoothness appearance after steam ironing. To further analyze wrinkling mechanism, fabrics’ wrinkle recovery rates which comprehensive characterize the physical and mechanical properties were tested with PhabrOmeter, including wrinkle recovery rates at normal temperature and after high temperature treatment. Then, the effect of temperature to fabrics’ wrinkle recovery rates and its relationship with fabrics’ smoothness appearance after ironing were studied. The results indicate that there are no significant correlations between the fabric basic parameters with smoothness appearance after ironing. The effect of temperature during ironing can improve the wrinkle recovery rates about 6%-21%. And no significant correlation is showed between smoothness appearance after ironing and wrinkle recovery rates. Keywords: Steam Ironing; mechanism; fabric parameters; wrinkle recovery rate.

Abstract Microstructural and mechanical properties of a pressureless sintered silver material were measured. The Microstructure of the pressureless sintered silver material had pores of less than 1 μm in size and some silver matrices sintered with nanoparticles between each other. The pressureless sintered silver material could be bonded on bare copper without applying an external pressure. After subjecting the material to a high temperature exposure test at 250 °C and for 1000 h, it showed no substantial change in microstructure and showed a constant Young's modulus of 14 GPa. The pressureless sintered silver material in this work did not show any embrittlement or increase in pore size after the high temperature exposure test, which demonstrated that the material has reliable physical and mechanical properties at temperatures up to 250 °C.

Super-absorbent polymer (SAP) was used as a self-curing admixture for cement-based materials. Two types of super-absorbent polymer and effect of super-absorbent polymer on fluidity and mechanical properties of mortars were investigated. The performance of the mortars cured for different ages was tested. The results showed that SAP could play a role of reserving water and reserving water of SAP particles A with an average diameter of 180 mm was more effective than that of SAP particles B with an average diameter of 80 mm, the optimal performance of reserving water was obtained at 0.07 wt.% of SAP particles A; Mechanical properties of hardened mortars with SAP particles A were better than those with SAP particles B, the favorably experiment ratio was 0.05 wt.% of SAP particles A.

Nanomaterials in the form of zero-, one- and two-dimensional nanostructures make a high-impact background for both science and technology. At the same time, the synthesis of bulk nanostructured materials remains the least-explored but challenging domain that allows combining the desired physical, chemical and mechanical properties and gives rise to nanoelectronics, nanomechanics, band-gap engineering, etc. The common methods of soft chemistry allow obtaining nanoparticles whose direct sintering unavoidably leads to the grain growth and lost of nanostructure. The extreme pressure is a parameter of choice to suppress the self-diffusion responsible for high-temperature recrystallization. The bulk nanostructured materials shows the superior fracture toughness and extremely high hardness as compared to corresponding microcrystalline bulks. The remarkable changes in physical and mechanical properties, however, do not affect the original thermal and chemical stability of the phase(s). All this opens unique opportunities for high-temperature superabrasive and electronic applications of such materials. Finally, the extreme pressure-temperature conditions are powerful and promising tool for grain-size control during direct solid-state phase transformations. The simultaneous variation of pressure and temperature makes possible to combine different nucleation, growth and aggregation regimes with high flexibility, and, therefore, to go deep into nanoscale engineering.
