Color Matching for Fiber Blends Based on Stearns-Noechel Model

引用

Journal of Donghua University(English Edition) 2006年第4期23卷 17-20页

作者：李戎宋阳顾峰 national research engineering center for dyeing and finishing of textiles Donghua University Shanghai 201620

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.

Synthesis of Fe_3O_4@SiO_2-Au/Cu magnetic nanoparticles and its efficient catalytic performance for the Ullmann coupling reaction of bromamine acid

引用

Chinese Chemical Letters 2018年第8期29卷 1301-1304页

作者： Aiqin Gao Hui Liu Liu Hu Hongjuan Zhang Aiqin Hou Kongliang Xie College of Chemistry Chemical Engineering and Biotechnology Donghua University national engineering research center for dyeing and finishing of textiles Donghua University

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.

Design of the reactive dyes containing large planar multi-conjugated systems and their application in non-aqueous dyeing

引用

Chinese Journal of Chemical engineering 2023年第2期54卷 264-271页

作者： Aiqin Gao Xiang Luo Huanghuang Chen Aiqin Hou Hongjuan Zhang Kongliang Xie College of Chemistry Chemical Engineering and BiotechnologyDonghua UniversityShanghai 201620China national engineering research center for dyeing and finishing of textiles Donghua UniversityShanghai 201620China

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.

The Synthesis of Cyclodextrin Derivatives with Ethilenic Bond and Their Application on Silk

Journal of Donghua University(English Edition) 2011年第3期28卷 312-316页

作者：方熙黄良晨赵曙辉黄芳 College of Chemistry Chemical Engineering and Biotechnology Donghua University national engineering research center for dyeing and finishing of textiles Donghua University

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.

Preparation and characterization of hollow carambola-shaped silver sulfide microspheres using a microwave-assisted template-free method

引用

Chinese Chemical Letters 2016年第3期27卷 451-453页

作者： Wei Su Rong Li Yan-Jun Xing College of Chemistry. Chemical engineering and Biotechnology of Donghua University Shanghai 201620. China national engineering research center for dyeing & finishing of textiles Shanghai 201620 China

A simple and convenient method, free of template, has been proposed to synthesize hollow carambolashaped Ag2 S microspheres with Ag NO3, thiourea（TU）, Na Cl and diethanolamine as reagents using a microwave-assisted method, at low temperatures of below 100 ℃. Powder X-ray diffraction（XRD）,scanning electron microscopy（FESEM） and high resolution transmission electron microscopy（HRTEM）were employed to characterize the morphology and composition of those microspheres. The results indicated that the hollow carambola-shaped silver sulfide microspheres（with high purity and homogeneous morphology） were prepared by an Ostwald ripening process. A possible formation mechanism of hollow carambola-shaped Ag2 S microspheres was proposed.

Molecularly Imprinted Polymer Based on GO-QDs as Enhanced Fluorescent Nanoscale Device for Specific Recognition of Target Protein

引用

Journal of Donghua University(English Edition) 2014年第5期31卷 603-608页

作者： DING Zhao-qiang GONG Xiao TAO Lei QUAN Jing NIE Hua-li ZHU Li-min College of Chemistry Chemical Engineering and Biotechnology Donghua University Shanghai 201620 China national engineering research center for dyeing and finishing of textiles Donghua UniveLity Shanghai 201620 China

In this work the enhanced molecularly imprinted optosensing material based on graphene oxide-quantum dots （ GO- QDs） was synthesized for highly selective and sensitive specific recognition of the target protein, bovine serum albumin （BSA）. Here, GO was introduced to enhance the efficiency of mass-transfer in recognition of target protein. Molecularly imprinted polymer coated GO-QDs using BSA as template （BMIP-coated GO-QDs ） exhibited a fast mass-transfer speed, which could be ascribed to the high volume of efficient surface area and high target recognition efficiency of the synthesized nanoscale device. Under optimal conditions, it was found that the BSA as target protein could remarkably quench the relative fluorescence intensity of BMIP- coated GO-QDs linearly in a concentration-dependent manner that was best described by a Stern-Volmer equation. The Ksv （Stern- Volmer constant） for template BSA was much higher than bovine hemoglobin （BHb） and lysozyme （Lyz）, implying a highly selective recognition ability of the BMIP-coated GO-QDs to BSA. This enhanced fluorescent nanoscale device may provide opportunities to develop a system that is efficient and effective and has potential in the design of highly effective fluorescent receptor for recognition of target protein in Droteomics studies.
