•Polyester fabric is modified by the lipase from the Pichia pastoris.•The lipase combined with non-ionic surfactant JFC exhibits good synergistic properties.•This cleaner production method for improving the hydrophilicity is applied in practice.A significant trend in textile manufacturing is the improvement in cleaner production processes using new biotechnological techniques. The biological enzyme lipase was used to improve the surface hydrophilicity of polyester fabric. The activity of a lipase (triacylglycerol hydrolase, EC 3.1.1.3) from Pichia pastoris and the effects of various parameters were investigated. The surface morphology of the modified polyester fiber was examined using reflectance spectroscopy and scanning electron microscopy. The synergetic effects of lipase combined with each of the five surfactants, namely JFC, AEO-9, HMA-474B, Tween-80, and sodium dodecyl sulfate (SDS), were investigated. The surfactants AEO-9, HMA-474B, and SDS significantly inhibited the lipase activity. Tween-80 decreased the lipase activity slightly. A combination of the non-ionic surfactant JFC and the lipase gave excellent synergy and significantly improved the hydrolysis of polyester fabric. This synergetic technique using a lipase combined with JFC was successfully used in cleaner production in a pilot plant to improve the hydrophilicity of polyester fabric. The moisture regains and the antistatic properties of the modified fabric were clearly improved.

•Application of oxidized chitosan.•Modified cotton fabrics with improved functionality.•Developed a facile and effective method for cotton functional finishing.In this research, modified cotton fabrics were prepared by pad-dry-cure technique from the aldehyde chitosan solution containing 3-aminopropyltriethoxysilane (APTES) and 1,2-ethanediamine (EDA) respectively. The structural characterization of the modified cotton fabrics was performed by attenuated total reflection ATR, scanning electron microscopy (SEM) and thermogravimetry (TG) analysis and physical mechanical properties were measured. The adsorption kinetics of modified cotton fabrics were also investigated by using the pseudo first-order and pseudo second-order kinetic model. The dyeing rate constant k1, k2 and half adsorption time t1/2 were calculated, respectively. The results show that the mechanical properties of different modified cotton fabrics were improved, and the surface color depth values (K/S), UV index UPF and anti-wrinkle properties were better than those of untreated cotton. Dyeing kinetics data at different temperatures indicate that Direct Pink 12B up-take on the modified cotton fabrics fitted to pseudo second-order kinetic model.

•New reactive disperse dyes containing a 3-chloro-2-hydroxypropyl were synthesized.•The electronic absorption property of them exhibited solvent dependence.•3-Chloro-2-hydroxypropyl group of them could form covalent bond with hydroxyl on cellulose.•The reactive disperse dyes for printing cellulose fabric had good building up.The printed cellulose and its blend materials have wide applications in many high-tech fields. Six new reactive disperse dyes (D1–D6) containing a 3-chloro-2-hydroxypropyl group based on epichlorohydrin were designed and synthesized. The electronic absorption spectra and their grafting printing property for cotton fabrics were investigated. The grafting mechanism on cotton fabric was also discussed. The results show that these dyes had larger bathochromic shifts in stronger polar solvent, dimethylformamide, than in the weaker polar solvents, acetonitrile and acetone. 3-Chloro-2-hydroxypropyl functional group of the dyes could form covalent bond with the hydroxyl group on cellulose by a nucleophilic substituted reaction. The good color yields of D1–D6 on printed cotton fabric were obtained by curing at 170–180 °C. The reactive disperse dyes for printing cellulose fabric had good building up and better printing property. The light fastness, rubbing fastness and fastness to perspiration of the printed fabric were good. The reactive disperse dyes have potential application in cleaner production of printing cotton and cotton/polyester blend fabrics.

•Structure and printing property of red reactive dyes for cotton were investigated.•The dye with numerous sulfonate groups had lower affinity for cotton.•The dye had potential application for cotton in printing urea-free.Cellulose fabric is an important printing substrate. Four red azo reactive dyes based on 1-naphthol-8-amino-3,6-disulfonic acid for cotton fabric printing were designed. Their UV–Vis spectra and printing properties for cotton were investigated. The relationship between the chemical structures of the dyes and their printing properties on cotton fabric was discussed. The results show that the color yield (K/S) values of the printed fabrics decreased with the increase of sulfonate groups, but the fixation and penetration of the reactive dyes on cotton fabric increased. The reactive dyes with fewer number sulfonate groups were sensitive to alkaline and urea. Whereas, the reactive dyes with numerous sulfonate groups were not sensitive to urea and had good leveling properties, penetration uniformity, and good wet fastness for cotton fabric. Surface wettability of all cotton fabrics printed with four dyes was excellent. It is possible to print cotton fabric urea-free using the reactive dyes with numerous sulfonate groups.

ABSTRACT
In this work, PEGylated chitosan derivatives were prepared and used to modified poly(ethylene terephthalate) (PET) fabrics. PET fabrics surface were etched by oxygen plasma before different concentrations PEGylated chitosan derivatives solution treatment. The effects of oxygen plasma and PEGylated chitosan derivatives on the surface properties of PET fabrics are investigated by Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). Surface wettability was monitored by water contact angle measurement and moisture regains. The results showed that the occurrence of oxygen-containing functional groups (i.e., CO, CO, and OH) of the plasma-treated PET and the surface coarseness increased from those of the untreated one. There was a layer film formed on the surface of PET fabrics after PEGylated chitosan modification. The combination treatment of oxygen plasma with PEGylated chitosans lightly lowered the breaking strength and elongation of PET fabric. That moisture regains increased and the contact angle decreased implied the hydrophilicity enhancement for the PET fabrics. In addition, dyeing property of PEGylated chitosan derivative modified PET was improved. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39693.

The flame retardant properties of the finished cotton fabrics and the synergetic effects of boron and nitrogen elements were investigated and evaluated by limited oxygen index (LOI) method. The mechanism of cross-linking reaction among cotton fiber, Tri-HTAC, and boric acid was discussed by FTIR and element analysis. The thermal stability and surface morphology of the finished cotton fabrics were investigated by thermogravimetric analysis (TGA) and scanning electron microscope (SEM), respectively. The finishing system of the mixture containing boron and nitrogen showed excellent synergistic flame retardancy for cotton fabric. The cotton fabric finished with mixture system had excellent flame retardancy. The LOI value of the treated cotton fabric increased over 27.5. Tri-HTAC could form covalent bonds with cellulose fiber and boric acid. The flame retardant cotton fabric showed a slight decrease in tensile strength and whiteness.

Dyeing wastewater is an important class of pollutants, which can be identified by human's eye. The release of some dyes in water streams has serious environmental impacts. Nano-cellulose hybrids containing polyhedral oligomeric silsesquioxane with multi-N-methylol (R-POSS) could be used as novel biosorbents for dyes. Adsorption properties of nano-cellulose hybrid for reactive dyes from aqueous solution were investigated. Reactive dyes, Yellow B-4RFN, and Blue B-RN, were used. The surface chemical ingredient of the hybrid was analyzed by X-ray photoelectron spectroscopy (XPS). The removal capacities of nano-cellulose hybrid materials for reactive dyes from aqueous solution were significantly higher than that of control cellulose. The adsorption kinetics of two reactive dyes, Reactive Yellow B-4RFN and Reactive Blue B-RN, were good fit with the second-order models. Nano-cellulose hybrids have potential application as biosorbents in the low concentration dyeing wastewater.

Abstract
Cellulose is an important biomass in natural material fields. Reactive polyhedral oligomeric silsesquioxane (R-POSS) bearing multi-N-methylol groups is novel high reactive POSS monomer. The nano-cellulose hybrids containing R-POSS were synthesized by crosslinking reaction. It was interesting to investigate properties and applications of hybrids containing R-POSS. In this work, nano-cellulose hybrids as novel biosorbent were used for adsorpting copper and nickel ions in aqueous solution. Adsorption kinetics and equilibrium isotherm of Cu2+ and Ni2+ on the nano-cellulose hybrids were investigated. The results showed that R-POSS had been grafted to cellulose macromolecule. The nano-cellulose hybrids could form new adsorptive position for heavy metal ions. The adsorption capacities of hybrid materials were obviously higher than that of control cellulose. The adsorption of heavy metal ions on nano-cellulose hybrids followed the second-order model. The equilibrium isotherms for adsorpting copper and nickel ions on the hybrids followed Langmuir isotherm model. Nano-cellulose materials containing POSS as biosorbents or ultrafiltration membranes would be used in separation of toxic heavy metal ions. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011.

Abstract
Reactive polyhedral oligomeric silsesquioxane (R-POSS) containing multi-N-methylol is a functional and attractive staring monomer for new reinforcement materials. R-POSS has excellent potential as a nanosized core for starburst dendrimers and highly reactive multi-N-methylol. R-POSS can be used for cellulose fabric finishing to improve its shape-memory performance. Factors affecting the crosslinking reaction of the cellulose with R-POSS were investigated. The physical properties and morphological structure of the cellulose fabrics modified with R-POSS are discussed with respect to the crease recovery angle, the whiteness index, micro-Fourier transform infrared spectroscopy, and scanning electron microscopy. The results show that the crease recovery angle of the fabric modified with R-POSS obviously increased. With increasing R-POSS concentration, the crease recovery angle of the modified fabric sharply increased. R-POSS readily crosslinked to cellulose and improved the elastic recovery of the cellulose fabrics. The surfaces of the cellulose fibers modified with R-POSS were smooth and full. The inclusion of R-POSS with dimethylol dihydroxyl ethylene urea to modify the cellulose showed very interesting results. It showed a good combination of an increase of crease recovery angle and a decrease in tensile strength. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

Dyeing properties of cellulose fabrics using micelle dyeing with low liquor ratio were discussed by color yields (K/S), color differences (ΔE), exhaustion (E), fixation (F) and reactivity (R) of three reactive dyes. The results show that reactive dye molecules could be solved in surfactant micelles and form stable dye-surfactant micelles. Micelles formed by dibutyl maleic acid ester sodium sulfate had good anti-agglomeration effect on dye solutions. Liquor ratio of micelle dyeing for cellulose fabrics could be reduced from 1:15 to 1:5. Leveling properties of three reactive dyes using micelle dyeing were good. The exhaustion, fixation and reactivity of all three dyes using micelle dyeing were similar with the conventional dyeing technology. Wet rubbing, washing and perspiration fastnesses of dyed samples using micelle dyeing were also good. Micelle dyeing with low liquor ratio can save a large amount of water and energy.
