Polypropylene (PP) fabrics were activated by an atmospheric pressure, dielectric barrier discharge to optimize the effects
of some discharge parameters on the dyeability of PP fabrics. Air and argon plasmas were used to modify the surfaces of the
fabrics, and the effects on dyeability were investigated when the treated fabrics were dyed by leuco and pigment forms of
vat dyestuffs. Surface properties of plasma-treated samples were characterized by Fourier transform infrared spectroscopy
(FTIR-ATR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Vat-dyed samples showed a significant
increase in color strength when PP fabrics were pretreated with atmospheric pressure plasmas of either argon or air. 相似文献

In this study, the effects of diet including different levels of olive cake were investigated on the fattening performance, blood parameters, certain slaughtering traits, and carcass quality of lambs. Thirty-six male lambs were used in the experiment. The lambs were randomly assigned to three groups with 12 lambs each. Groups included control, 12.5 and 25% olive cake (OC). The mixed feeds were offered ad libitum. All lambs were also allowed to consume alfalfa hay (83.8 g DM/animal/day). The experiment lasted for a period of 56 days. The effect of different levels of olive cake was not found different in fattening performance values of lambs in 0–56 days (P > 0.05). Carcass weight, pH, and yield were not different (P > 0.05). While the values of color parameters, cooking loss, tenderness, and ether extract level of longissimus dorsi muscle (MLD) was not found different (P > 0.05), it was determined that the levels of olive cake increased the water-holding capacity of meat (P < 0.05). Furthermore, although the levels of olive cake were shown to decrease total n-3 and total saturated fatty acids (Σ SFA), they also increased total n-6, n-6/n-3 ratio, total monounsaturated fatty acids (Σ MUFA), and total polyunsaturated fatty acids (Σ PUFA) were not different (P > 0.05). 相似文献

Antimicrobial treatments have become more important for the textile materials especially used in sportswear, activewear, and
casual wear since they can easily be contaminated by perspiration leading to bacterial growth and body odor. In this work,
antimicrobial activity of chitosan in a silica matrix on pretreated wool fabrics was studied. The pretreatment processes were
applied by two different ways (enzymatic and enzymatic+hydrogen peroxide). Afterwards chitosan solutions were applied to the
untreated samples and to the samples that were pretreated by two different ways to give antimicrobial effects. The antimicrobial
activity of wool fabrics treated in various methods was assessed before and after repeated washings (up to 10 cycles) by the
application of standard test method AATCC 147-1998. The morphology of the treated fabrics was investigated by SEM and their
characterizations were made by the FT-IR spectral analysis. Results revealed that pretreatment ways and chitosan application
methods were quite important for adsorption and diffusion of chitosan on wool fabrics and washing stability. From the SEM
images, it was clearly observed that pretreatment processes caused some degradation on the surface of the fiber; but combined
processes were found to be less degradative and more effective. 相似文献

The dyeing properties of the polypropylene (PP) fabrics using cationic dyestuffs were investigated after surrounded air atmospheric cold-plasma treatment. Surrounded air plasma (SAP) was used to modify fabric surface and to optimize the effects of some discharge parameters on dyeability. Surface morphology and physical-chemical properties of plasma treated fibers were also characterized by Fourier transform infrared attenuated total reflection spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. Activated surfaces by SAP were grafted with different compounds: 6-aminohexanoic acid, acrylic acid, and hexamethyldisiloxane. Dyeing the plasma-induced grafted PP fabric with basic dye was quite satisfactory when high color strength and good fasteness were considered. 相似文献

Fires have a noteworthy role to play with regards to ecological and environmental losses in Mediterranean forests. In addition to ecological impacts, fire may create economic, social as well as cultural changes. The detection of fire-scars has critical importance to help decrease losses. In the present study, forest fires recorded in Antalya, one of the most important ecological and tourist regions within the Western Mediterranean, were clustered and mapped. Since the dominant factors and devastation records derived from the cases had nominal-scaled properties, a categorical data-based nonparametric clustering algorithm was performed in this evaluation. The proposed tool, k-modes algorithm, uses modes instead of means for clustering. The algorithm may be implemented quickly and does not make distributional assumptions concerning the available data. It uses a frequency-based method to update the modes of the fires. The derived modes from the maps may be useful information for local authorities to manage. In conclusion, the proposed nonparametric clustering procedure may be employed to build a decision-support system to monitor and identify fire activities and to enhance fire management efficiency. 相似文献
