In this paper, the hemp / cotton / polyester mesh knitted fabric (Han / C / T) is treated by alkali treatment, conventional dyeing and alkali pre-treatment dyeing. We have obtained the conclusion that alkali treatment improves the dyeing effect. Alkali pre-treatment dyeing was done after alkali treatment. The fabric dyeing effect is improved obviously. The optimum process come from orthogonal experiment (dyes 2.5% owf, Na2SO4 :30g/L, Na2CO3:10g/L, liquor ratio (1:50) and 90°C×50 min). Through this optimum process, dyeing effect for hemp / cotton / polyester mesh knitted fabric is close to the pure cotton fabric dyeing effect.

t is pre-mordant dyeing. Dyeing property of Carmine, gardenia yellow and sodium copper chlorophyll on cotton fabrics which were pre-treated by metal mordant (FeSO4AlCl3 and ZnCl2 ) was studied. The reasonable pre-treatment was determined by comparing the color depth (K/S value) of dyed samples. And then, the dyed samples were treated with no-iron finishing resin 931-33 to fix the color. The result shows that the color depth of cotton fabric is greatly improved after determined pre-treatment, and the washing fastness is improved after color fixing.

Pre Treatment

In this study, the surface modification of arsenopyrite and pyrite with low temperature oxygen plasma was developed as an effective approach to improve the flotation separation efficiency of minerals. The micro-flotation experiments results indicated that plasma pre-treatment can achieve selective flotation of arsenopyrite from pyrite. The XPS analysis results indicated that the oxidation degree of plasma-modification arsenopyrite surface is much higher than that of pyrite. A large number of sulfide components on the surface of the mineral were oxidized to highly-valence hydrophilic oxides by plasma pre-treatment. ICP-MS analysis results revealed that the dissolution rate was determined by the oxidation degree of minerals and plasma modified accelerated the dissolution of arsenopyrite and pyrite. Zeta potential determination results confirmed that plasma can keep a relatively higher adsorption of SBX on the pyrite surface but inhibit the adsorption of collector onto the arsenopyrite surface.

Uv Protective Properties

Low-pressure oxygen plasma created by an electrodeless radiofrequency (RF) discharge was applied to modify the properties of cellulosic fibrous polymer (cotton) in order to improve adsorption properties towards zinc oxide (ZnO) nanoparticles and to achieve excellent ultraviolet (UV) protective properties of cotton fabric. The chemical and physical surface modifications of plasma-treated cotton fabric were examined by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The mechanical properties of plasma-treated samples were evaluated, measuring strength and elongation of the fabrics. The quantity of zinc on the ZnO-functionalized cotton samples was determined using inductively coupled plasma mass spectrometry (ICP-MS) and the effectiveness of plasma treatment for UV protective properties of cotton fabrics was evaluated using UV-VIS spectrometry, measuring the UV protection factor (UPF). The results indicated that longer plasma treatment times cause higher concentration of oxygen functional groups on the surface of fibres and higher surface roughness of fibres. These two conditions are crucial in increasing the content of ZnO nanoparticles on the fibres, providing excellent UV protective properties of treated cotton, with UPF factor up to 65.93.
