In order to investigate the impact of double etherification on the adhesion to fibers and desizability of corn starch , a series of doubly etherified corn starch (DES) with the total degree of substitution (DS) values of 0.014–0.034 were prepared by simultaneous quaternization and sulfonation of acid-converted corn starch (ACS) with N -(3-chloro-2-hydroxypropyl) trimethylammonium chloride (CHPTMA) and 3-chloro-2-hydroxy-1-propanesulfonic acid sodium salt (CHPS-Na). The influence of double etherification on the adhesion of starch to cotton and polyester fibers was evaluated. It was found that etherification was able to increase the tensile strengths of starch to the fibers, and the strengths gradually increased as the etherification levels rose. Moreover, etherification was capable of displaying a positive effect on the desizability of starch as determined by measurements of swelling capacity of DES films and the time required to break the films. Etherification also enhanced the paste stability and moisture regain of the films. The DES with a total DS value of 0.034 showed potential for ameliorating the adhesion of starch to cotton and polyester fibers for warp sizing.

In this study, a series of poly(terminal vinyl dimethicone-co-methyl methacrylate-co-n-butyl acrylate)/pigment composite particles (P(DMS-Acr)/PB CPs) were successfully prepared via miniemulsion polymerization and their latex film microstructures on were examined carefully using transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM) and so on. Significant phase separation was observed after film formation, and the copper phthalocyanine blue (PB) particles tend to distribute in the polysiloxane island phase. After baking at 120 °C, the protrusions were generated. With increasing amount of vinyl terminated polydimethylsiloxane (ViPDMS) or baking time, the number of the protrusions became more and the appearance of the protrusions tends to be sharp. When the P(DMS-Acr)/PB CPs were applied in fabric printing, a continuous film was formed on the surface of the fabric at room temperature and therefore the gaps between yarns were blocked. However, the gaps in the fabric reappeared after baking at 120 °C, which could be attributed to the rapid flow of the polymer component. Finally, the fiber was coated with a layer of latex film containing a large number of mastoid structures, and the printed fabric could still retain the majority of the gaps between yarns and between fibers. Therefore, the printed fabric exhibited excellent performances such as good air permeability, softness, and rubbing fastness.

Dyes containing cyano group have the advantages of bright colours and high molar absorption. However, most cyano-containing disperse dyes are not used for alkaline dyeing as they are easily hydrolysed under alkali conditions. Herein, cyano-containing disperse dyes for alkaline dyeing were designed by introducing non-hydrolysable phenylethyl and potentially alkali-hydrolysable ethyl benzoate in adjacent positions to the cyano group, and the effect of the adjacent groups on the alkali resistance of cyano-containing dyes was investigated. Polyester fabric (PET) was dyed under different acidic or alkali conditions by the disperse dyes, then the hydrolysis energy barrier of cyano on the dye and the binding energy of dye-dye and dye-PET under the dyeing conditions were calculated via Density Functional Theory (DFT). The results showed that the cyano-containing disperse dyes with an adjacent benzene ring structure had good alkali resistance in a 5 g/L NaOH dye bath. DFT simulations confirmed that the adjacent phenylethyl did not have a significant effect on the hydrolytic energy barrier of the cyano group, while the adjacent ethyl benzoate reduced the hydrolytic energy barrier of the cyano group. The introduction of an adjacent benzene ring reduced the dye-dye binding energy, contributing to the increasement of dyeing rate at the beginning of the dyeing process. The designed cyano-containing dyes with adjacent benzene rings achieved a colour fastness level of 4–5 or above in various acid and alkali conditions.

Thermo-responsive textile is newly developed and has wide application potentials in various fields. As the most commonly used textile, polyester has advantages in easy care, great durability and low cost. Since it has no reactive groups in fiber for surface functionalization, amino groups were generated by aminolysis in this study. By applying alkali deweighting during the aminolysis process, more -NH2 was produced. Poly(N-isopropylacrylamide) (PNIPAAm) was then grafted onto the surface via surface-initiated atom transfer radical polymerization. Infrared and X-ray photoelectron scanning measurements confirmed the success of PNIPAAm grafting. The thermo-switchable surface wettability was then explored by the test of surface wettability and fiber swelling–deswelling behavior. When the temperature rose, the surface switched from hydrophilic to hydrophobic as the contact angle transited from 0° to 120° reversely. This work established a feasible way and provided a new insight for preparing thermo-responsive polyester fabrics with smart cleaning and smart comfort properties.

Summary Wearable supercapacitors have broad application prospects in emerging portable devices. To realize the large-scale application, it is necessary to develop a low-cost and large-scale method to fabricate wearable electrode with high electrochemical performance. Here, polyaniline supported by graphene coated polyester textile (PANI/GPT) electrode is prepared through a simple and low-cost method. First, graphene ink with high concentration is prepared, and then the polyester textile is coated by graphene through a repeatedly soaking-drying process. Subsequently, PANI/GPT electrode is prepared by electrochemical deposition of polyaniline (PANI) on graphene coated polyester textile. The ratio of PANI in the textile electrode has been systematically modified and the obtained textile electrode possesses good energy storage performance with specific capacitance reaching 896.50 F g −1 and good rate capability. The assembled flexible supercapacitor also owns excellent flexibility with capacitance retention of 95.10% after bending for up to 5000 cycles. Such high-performance textile electrodes and the low-cost method can be widely applied to develop other wearable energy storage devices.

To further improve the color yield and color fastness of disperse dyes (DDs) in washing-free printing, fluorosilicone-modified polyacrylate (FSMPA) was prepared as a new washing-free printing binder. The structure, thermal behaviors, surface characteristics, and washing-free printing properties of FSMPA were intensively investigated. The migration-diffusion-fixation mechanisms of DDs from a polymer binder film to PET were tentatively explored. The results showed that when the molar ratio of 1,3,5-tris(3,3,3-trifluoropropyl) methylcyclotrisiloxane (D 3 F ) to octamethylcyclotetrasiloxane (D 4 ) was 1:10 in the preparation of the modifier double-terminated vinyl polyfluoroalkyl siloxane (DVFS) and the dose of DVFS in the preparation of FSMPA was 9%, the printed polyester fabric exhibited excellent washing-free printing properties. Compared with polyacrylate (PA) and silicon-modified polyacrylate (SMPA), FSMPA has better color yield and color fastness. The glass transition temperature of FSMPA was decreased, the enrichment of fluorosilicone chains on the surface of FSMPA film was facilitated, and the hydrophobicity of FSMPA was improved. Thus, the difference in solubility parameters between the DDs and polymer binder film was increased, and the migration of the DDs from the FSMPA film to the PET substrate was promoted.

Disperse-dye wash-free digital inkjet dyeing, which combines digital jetting technology with disperse-dye wash-free dyeing technology, is a simple process that reduces carbon and pollutant emissions, conserves dyes and chemical materials and delivers a fast response. In this study, based on the principle of solubility parameter, a series of wash-free digital inkjet-dyeing waterborne polyurethane (WPU) which directionally delivered the disperse dyes, were prepared by employing isophorone diisocyanate (IPDI) as the hard monomer, polybutylene adipate (PBA) as the soft segment and polydimethylsiloxane (PDMS) as the modified soft segment. The results showed that the WPU film prepared from 6 wt% PDMS and 42 wt% IPDI, exhibited the highest water resistance, mechanical and adhesive properties, and directional dye delivery among the films. The optimal dosage of WPU in the wash-free ink was 6 wt%. Compared with the pure dye ink, the front colour yield of the inkjet-dyed fabrics with WPU wash-free ink reached 16.08 and improved by 18.1%. The colour fastness to dry/wet rubbing achieved grade 4-5 and grade 3-4, respectively. It demonstrated the good prospects of WPU in wash-free dyeing application. In particular, the approach promises inkjet-dyed polyester fabrics of high surface colour and fastness under no reduction-cleaning/washing procedures.

Colored wastewater has to be treated before its discharge, which is a great challenge for the protection of the ecological environment. A novel polymeric dye with nanoparticle morphology has been handily designed to dye polyester fabrics and can be fully recycled to avoid a large number of dyes discharge. It solves the colored wastewater pollution problem in the dyeing process from the source. The colored polyurethane nanoparticles with an average size of 500 nm are prepared via emulsion polymerization . The average content of the colorant monomer on nanoparticle is 2.77%. The colored nanoparticle demonstrates no thermal degradation at 110 °C and no damage under 20 MPa, which means good adaptability for the high-temperature dyeing process. The color depth of dyed polyester fabric can be easily adjusted by changing the concentration of colored nanoparticles in dyebath. The colored nanoparticles in the residual dyebath can be collected by extraction filtration leading to the concentration decreases from 11 mg mL −1 to 0.000025 mg mL −1 after filtered. Both the colored polyurethane nanoparticles and filtered water are fully reused for the next dyeing process to achieve the purpose of avoiding water consumption and residue dyes discharged. This work can promote the development of green and clean dyeing processes in the textile industry .

The printing of polyester (PET) fabrics using binders and disperse dyes is an environmentally less harmful technique due to the exclusion of water-intensive washing processes. Unfortunately, the conventional polyacrylate (PA) binders are inapplicable for this printing technique as the high PA-disperse dye compatibility restrains the migration of disperse dye molecules from binder films into PET fabrics. Herein, we demonstrate a rational design and synthesis of novel PA binders by copolymerizing fluorosilicone monomers with multi-vinyl groups for the sustainable printing of PET fabrics. The incorporated fluorosilicone functionalities significantly decrease the solubility parameter of PA, facilitating the dye molecules migration toward PET fabrics. Meanwhile, the crosslink structure formed via vinyl groups restrains the migration of polymer chains and thus allows for the anchor of F/Si segments, enabling the continuous migration of disperse dyes. As a result, both the utilization ratio of disperse dyes and the color yield and fastness of printed PET fabrics are substantially improved. Moreover, the washing-free printing process using the developed binder can reduce 73% of water consumption, 74% of energy input, and 100% of wastewater discharge over the traditional printing process. Our study may provide insights into rational design of binders for the sustainable printing of PET fabrics.

Polyester fabrics suffer from inherent flammability and tend to produce significant molten droplets during combustion, which severely restricts their practical applications. In this study, polyphosphazene microspheres (PZS) were synthesized through a nucleophilic substitution reaction and subsequently combined with polydimethylsiloxane (PDMS) to form a multifunctional coating on polyester fabrics (PF). And the wear resistance, hydrophobicity, and flame retardant properties were systematically investigated. The results revealed that PZS exhibited a uniform particle size of 572 nm with good thermal stability, enabling homogeneous distribution on fabric surfaces. The fabric composite maintained a water contact angle exceeding 140° both before and after wear resistance testing, demonstrating excellent wear resistance and sustained superhydrophilicity. PZS@PDMS can promote the early degradation of PF to generate a more stable and dense carbon layer, with the residual carbon content increasing from 13.22 % of pure PF to 24.48 %. Cone calorimetry results showed that PF/8PZS@PDMS had excellent flame retardancy, with peak heat release rate and total heat release decreased by 77 % and 57 % to pure PF. These enhancements were attributed to the synergistic effects of catalytic carbonization, gas-phase dilution effect, and free radical quenching effect. This article provided a new method for developing polyester fabrics with integrated flame-retardant and hydrophobic functionalities.

In this study, amphiphilic starch prepared by phosphorylation and octenylsuccinylation is surveyed to identify its effect on the adhesion of starch to cotton/polyester blend fibers at different temperature. Acid-thinned cornstarch (ATS) is phosphorylated and octenylsuccinylated with pentasodium triphosphate and 2-octenylsuccinic anhydride, respectively, to improve upon adhesion to cotton/polyester blend fibers. Two series of amphiphilic starch samples with different levels of the substitution (DS) are derived for determining desirable level of starch modification in sizing. Amphiphilic starch paste shows strong adhesion to cotton/polyester blend fibers than ATS paste. It is found that the modification reduces the crystallinity, changed the morphology, improves moisture regain, alleviates the adverse influence of starch retrogradation, and improves adhesion to fibers and desizing efficiency. The adhesion of amphiphilic starch paste to cotton/polyester blend fibers at 60 °C is statistically higher than adhesion of ATS at 95 °C. The amphiphilic starch with a total DS of 0.06 shows the highest potential use for strong cotton/polyester blend warp sizing due to its good sizing properties.

In this study, Cu/Ag/polydopamine (PDA)/polyester (PET) fabrics were fabricated for multi-functional textiles. The PET fabrics were firstly modified by dopamine to form a polydopamine (PDA) layer on the fiber surface, then Ag nanoparticles (Ag NPs) were anchored on fiber surface through chelation between PDA and Ag+ions, and the Ag NPs were further used as catalytic seeds for in situ reduction of Cu nanoparticles (Cu NPs). The surface morphology, chemistry, and crystalline structure of the prepared PET fabrics were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). As expected, Cu NPs were evenly dispersed on the surface of fibers. The Cu/Ag/PDA/PET fabrics showed good antibacterial property againstEscherichia coliand exhibited excellent electromagnetic interference (EMI) shielding ability. The Cu/Ag/PDA/PET fabrics with high performance antibacterial and EMI shielding properties can be applied as functional protective textiles.Keywords:Cu NPs;Ag NPs;polydopamine;PET fabrics;antibacterial;electromagnetic interference shielding
