In previous research much effort has been devoted to the geometry of woven fabrics and relat-ed problems under the assumption of constant yarn configuration in
In the network of a mechanical system,force F and velocity V are related by mechanicalimpedance Z as:Z=F/V.In this paper,we are going to discuss two cases:①Z=0
Friction and wear properties of nitrogen-implanted GCrI5 bearing steel and 40Cr structuralsteel were studied under different implantation conditions. It is foun
The lower strength of friction spun yarns has became a key problem that hinder the develop-ment of friction spinning,especially in high speeds and fine yarns.In
The process of treating the PET tire cord (210D/3×2) by low temperature nitrogen and airlow temperature plasma and dipping in RFL (resorcinol-formaldehyde-
The influence of reaction temperature,reaction time, system pressure and catalysts on the re-duced viscosity(η<sub>sp</sub>/C)and shear viscosity(η<sub>a</sub>
The viscosities of chitosan-HAC in aqueous solution with various amount of NaAC have beenmeasured.Based on the analysis of experimental data,an empirical equati
