The type of disruption and the location of the disruption of the samples are important monitored factors.
However this difference is caused by the way in which the 2D textile is manufactured, and not by the properties of the material.

Several factors affect the indoor air quality, among which ventilation, human occupancy, cleaning products, equipment and material; they might induce the presence of aerosols (or bioaerosols in the presence of biological components) nitrogen oxides, ozone, carbon monoxide and dioxide, volatile organic compounds, radon and microorganisms.
The mechanical systems of extraction and/or filtration can also be used to control air quality.
Several factors affect indoor air quality, among which are the ventilation, human occupation, cleaning products, existence of polluting materials and equipment, resulting in the presence of aerosols or bioaerosols (when biological components are present), nitrogen oxides (NOx), ozone (O3), carbon monoxide (CO), carbon dioxide (CO2), formaldehyde (CH2O), volatile organic compounds (VOCs), radon and microorganisms.
Thus it can be stated that nanotechnology allows designing and creating new materials with improved physical properties [9,10].
A large number of extremely important factors in the filter development are considered, such as the use of artificial biomaterials at the nano-scale, due to its high antimicrobial activity and the performance/cost balance, compared to those on the market for air filtration systems.

The strain relationship between them is projective corresponding to each other, and is affected by the material properties.
Recent papers show that there are several factors which lead to the formability decrease of TWB.
Efforts have also been paid to improve TWB formability which focuses on the factors such as welding technologies, the thickness of parent metals as well as stress differences [7, 8].
Our previous work have shown that the integrated strength, which is affected by material properties and thicknesses, is a main factor to degrade the formability of TWB, and the discrepancy of integrated strengths on base metals can affect both cracking trend and cracking type.
Material properties used in the model are listed in Table 1.

Also, the effect of blank geometry and material properties on forming force in fine-blanking process was studied by theoretical formulation and experimental approach.
Introduction In sheet metal forming processes, the forces and forming limit are affected by a number of factors, such as material properties and tool design.
These three factors determine whether production by fine blanking can be rated as simple, medium-difficult, difficult or impossible.
Also, the material properties are listed in “Table 2”.
This factor and thus the blanking factor, is further affected by the geometrical form of the part, the effectiveness of lubrication, and the sharpness of the active elements in the tool.

Introduction The excellent high temperature mechanical properties of Inconel 718 make it the most widely used material for hot structural parts of jet engines.
Therefore, not surprisingly, fatigue properties of SLM metals vary considerably as well.
Static mechanical properties of heat treated SLM Inconel 718 were determined using tensile specimens tested in a servo-hydraulic test machine.
They are compared to standard properties in Table 2.
This may indicate that roughness is not the unique factor affecting the fatigue behavior.
