The results indicated that the prepared carbon black/latex dispersion had excellent freeze–thaw stability. Cotton fabric that was cationised with 3 g/l of 3-chloro-2-hydroxypropyltrimethyl ammonium chloride at a liquor ratio of 30:1 can be optimally dyed with 4% owf carbon black/latex under the conditions of pH 7.2, 60 °C, and 1 h. The adsorption behaviour of the carbon black/latex towards cationised cotton fabric followed the Langmuir adsorption isotherm, with a lower dyeing rate and a better colour levelness than the ordinary carbon black dispersion with binder.

Tannage Résumé : A flow-injection spectrophotometric method for the determination of aluminium(III) has been described. The method is based on the reaction Al(III) with morin to form a yellow complex with maximum absorption at 425nm in the presence of cationic surfactant CPC and glacial acetic acid. In the presence of cationic surfactant CPC, the sensitivity of the chromogenic reaction was greatly improved. Under the optimized conditions, calibration graphs for Al(III) are linear in the range 5-150g l-1 with a detection limit of 0.0125g l-1 (3σ). The reproducibility was satisfactory with a relative standard deviation of 1.7% for ten determinations of 50μg l-1 Al(III). With a sample solution of 450μl being injected, the sampling frequency is 60/h.

Langues : Anglais (eng) Catégories : Dispersions et suspensions Encre jet d'encre Impression jet d'encre Nanoparticules Pigments Stabilité thermique Index. décimale : 667.3 Teinture et impression des tissus Résumé : Pigment ink was formulated with nano-coated pigment dispersion, prepared via mini-emulsion polymerization. To study the effect of nano-coated pigment, surfactant and humectant on ink-jet printability, the trajectory of droplets with different pigment ink composition was monitored. The effect of ink formulation on the accuracy of printing process of the pigment ink was discussed by study on line width and edge contour of printed patterns. Experimental results indicated that the additives and properties of the pigment ink had a great influence on droplet formation and precise positioning of the printed patterns. The optimal composition for the pigment ink as following: nano-coated pigment dispersion was 20% w/w, surfactant (S-465) was 1.5% w/w, humectant (diethylene glycol) was 30% w/w and defoamer (FB-50) was 0.1% w/w. The prepared pigment ink exhibited excellent freeze–thaw, thermal and centrifugal stability. In addition, the optimal formula was beneficial to form a stable droplet and obtain high precision patterns.

Mechanism and properties of coloured nanoscale SiO2 prepared from silica and reactive dyes / Liping Zhang in COLORATION TECHNOLOGY, Vol. 132, N° 5 (10/2016)  

[article]  inCOLORATION TECHNOLOGY > Vol. 132, N° 5 (10/2016) . - p. 399-406 Titre : Mechanism and properties of coloured nanoscale SiO2 prepared from silica and reactive dyes Type de document : texte imprimé Auteurs : Liping Zhang, Auteur ; Min Li, Auteur ; Anli Tian, Auteur ; Shaohai Fu, Auteur Année de publication : 2016 Article en page(s) : p. 399-406 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorants réactifs Dioxyde de silicium Matériaux -- Coloration Nanotechnologie Photostabilité Résistance chimique solvants Index. décimale : 667.3 Teinture et impression des tissus Résumé : KH560-modified SiO2 was prepared using tetraethyl orthosilicate (TEOS) and ?-(2,3-epoxypropoxy) propytrimethoxysilane (KH560) by the sol–gel method and then coloured with CI Reactive Blue 4 (X-BR) to prepare coloured nanoscale SiO2. The antisolvent performance and the results of cross-polarisation/magic angle spinning 13C nuclear magnetic resonance and Fourier transform infrared spectroscopy showed that the reaction of X-BR with KH560-modified SiO2 is a two-step process : X-BR is firstly adsorbed by KH560-modified SiO2 via van der Waals forces, and then nucleophilic substitution occurs between dichloro triazine and the epoxy group. The grafting ratio of X-BR on KH560-modified SiO2 reached 95% under optimum conditions, i.e. a mass ratio of KH560 to TEOS of 20%, a temperature of 40 °C, a pH of 8.5, and a reaction time of 5 h. X-ray diffraction analysis and transmission electron microscopy showed that the coloured nanoscale SiO2 was amorphous, with a mean diameter of 216 nm. Experimental application showed that the coloured nanoscale SiO2 had excellent stability to solvents and alkaline solution, and the absorptive capacity of the coloured nanoscale SiO2 in the 200–400 nm region was higher than that of X-BR. The light fastness of the coloured nanoscale SiO2 reached 5–6 grade.

Modification of carbon black pigment : cotton fabric colouring and anti-bacterial finishing / Liping Zhang in COLORATION TECHNOLOGY, Vol. 136, N° 4 (08/2020)

Dispersions et suspensions Fibres textiles -- Analyse Noir de carbone Teinture -- Fibres textiles Textiles et tissus Index. décimale : 667.3 Teinture et impression des tissus Résumé : Functional polymer modified carbon black (CB) pigment (P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB) with reactive epoxy and quaternary ammonium groups was designed and prepared via a thiol‐ene click chemistry reaction, and its dispersion ability in the aqueous phase, as well as its colouring and anti‐bacterial properties for cotton fabrics, were investigated. In considering both dispersion ability and reactive ability to cotton fabric, the mole ratio of the monomers (methacrylatoethyl trimethyl ammonium chloride [DMC] and 3‐chloro‐2‐hydroxypropyl methacrylate [CHPMA]) was discussed. Morphology and chemical properties of P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB were tested by scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis and X‐ray photoelectron spectroscopy, resulting in a weight content of copolymer (DMC‐co‐CHPMA) in P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB of ca. 18%. P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB was fixed onto cotton fabric via a nucleophilic‐substituted reaction between reactive epoxy groups on the CB surface and the hydroxyl groups of cotton fabric, which endowed good fastness to cotton fabric without either a fixing or an adhesive agent. Also, coloured cotton fabric demonstrated excellent anti‐bacterial activity towards Staphylococcus aureus and Escherichia coli O157:H7.
