Prediction of the formula for matching a given color standard by blending pro-dyed fibers is of considerable importance to the textile industry. This kind of formulation suffers from a lack of computer-aided tool to assist the colorist attempting to find a good recipe to reproduce a target color. In this article a tristimulus color matching algorithm based on Stcarns-Noechel model is proposed. This algorithm was run to predict recipes for 36 viscose blends. The maximum color difference is 0.97 CIELAB units. It is demonstrated that the algorithm can be used in color matching of fiber blends.

Two novel N-heterocycle-containing benzotriazole compounds, 5-（5-chloro-2-benzotriazolyl）-6-hydroxy-l,4-dimethyl-3-car- bonitrile-2-pyddone （2） and 4-（5-chloro-2-benzotdazolyl）-5-methyl-2-phenyl-3-pyrazolone （4）, were synthesized from reactant 4- chloro-2-nitroaniline via diazotization, azo coupling, reductive cyclization and acidification. Their structures were confirmed by Fr-IR, 1H NMR, mass spectroscopy and elemental analysis. Their spectral properties were investigated and compared with that of a common commercial benzotriazole UV absorber Tinuvin 326. It is found that the novel N-heterocycle-containing benzotriazole compounds exhibit sharp single peak in the range of 280-400 nm and have much higher molar extinction coefficients than that of Tinuvin 326. Their anti-UV protection properties on polyester fabric were also evaluated and compound 4 was much superior to compound 2 due to its higher exhaustion.

Novel magnetic core/shell bimetallic Au/Cu nanoparticles（Fe_3O_4@SiO_2-Au/Cu NPs） were prepared using SiO_2-coated iron oxide（Fe_3O_4@SiO_2） as a supported material. The magnetic Fe_3O_4 colloidal nanocrystal clusters（CNCs） as nano-core were modified with a silica coating for improvement stability and superficial area of the Au-Cu particles. The morphological structure and chemical composition of the Fe_3O_4@SiO_2-Au/Cu NPs were characterized with high-resolution transmission electron microscopy（HRTEM）, energy-dispersive X-ray（EDX） and X-ray photoelectron spectroscopy（XPS） analyses. The Au and Cu NPs were deposited on the SiO_2 surface in a highly dense and well dispersed manner with an average size of approximately 5 nm. The Fe_3O_4@SiO_2-Au/Cu NPs as magnetic nano-catalysts were applied to the Ullmann coupling reaction of bromamine acid to synthesize 4,40-diamino-1,10-dianthraquinonyl-3,30-disulfonic acid（DAS）. The prepared Fe_3O_4@SiO_2-Au/Cu NPs exhibited efficient catalytic activity with higher conversion and selectivity. A bromamine acid conversion of 97.35% and selectivity for DAS of 88.67% were obtained in aqueous medium. The magnetic nano-catalysts can be readily separated from the reaction system and reused. This new nano-catalytic reaction represents a useful and attractive cleaner production system. The new catalyst system has important and potential applications in dye and pigment industry.

The development of pollution-free dyeing technology, including anhydrous dyeing and non-aqueous dyeing technologies, has always been an important way and research hot in energy conservation and emission reduction. Designing new structural dye molecules is the key to water-saving dyeing ***, three reactive dyes were designed and synthesized, which contained large planar multiconjugated systems and multi-reactive groups. The designed reactive dyes are expected to have high affinity and high fixations in non-aqueous or small bath dyeing processes. The reactive dyes were applied in the decamethylcyclopentasiloxane(DMCS) reverse micelle dyeing for cotton fabric. High exhaustion rate of 99.35%, 98.10% and 98.80%, and fixation rate of 95.15%, 96.34% and 94.40% for three dyes, R1,R2 and R3, could be respectively obtained. The dyes can be fully utilized and had excellent dyeing performance, fastness and levelling properties under the revere micelle dyeing. The cotton fabric is like an oil-water separator in the dyeing process, where the dye micelles rapidly absorb and permeate into the cotton fibers. DMCS circulates around the fabric to transfer mass and energy. After dyeing, the solvent can be separated quickly and reused. The new reactive dyes containing large planar and multi-conjugated systems have potential application in green and sustainable dyeing technology with less wastewater and higher utilization.

A new coordination compound, [（CuI）（Btd）]n （1, Btd = 2,1,3-benzothiadiazole）, was obtained at room temperature by the reaction of 2,1,3-benzothiadiazole with CuI and KI saturated aqueous solution. It was characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction analysis and photoluminescence. The complex crystallizes in the triclinic Pi space group, with a = 4.1620（6）, b = 10.4590（15）, c = 10.5052（15） A, a = 69.310（2）, β = 83.608（2）, γ = 78.873（2）°, V = 419.30（10） A3, Z = 2, C6H4N2SCuI, Mr = 326.61, Dc = 2.587 g/cm^3, F（000） = 304 and/^（MoKa） = 6.464 mm-1. The final R = 0.0418 and wR = 0.0936 for 1451 observed reflections with 1 〉 2σ（I） and R = 0.0422 and wR = 0.0939 for all data. In the complex, the Cu atoms are coordinated by one nitrogen atom and three iodine atoms to form a double-stranded stair, and such stairs are further linked to build a 2D framework via C-H…I interactions.

The cyclodextrin (CD) derivatives with ethilenic bonds mono-(2-O-tosyl)-6-acryloyl-β-cyclodextrin (β-CD-2-OTs-6-A) and 6-acryloyl-β-cyclodextrin (β-CD-6-A) were respectively synthesized. β-CD-2-OTs-6-A was prepared by the reaction propylene chloride with β-CD-2-OTs. β-CD-6-A was synthesized by the reaction propylene chloride with β-CD. The most suitable pH value for β-CD-6-A grafted onto silk fabric was proved to be 5. The optimal condition for grafting β-CD-2-OTs-6-A onto silk was proved: monomer concentration of 20% on weight of fabric(o.w.f), potassium persulfate of 1.85% o.w.f, liquor ratio of 1∶50, pH=5, and treated 30 min at 80 ℃. Compared with β-CD-6-A, the grafting reaction has a higher graft yield while β-CD-2-OTs-6-A acts as the monomer.
