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.

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.

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.

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.

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 .

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, 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

The printing and dyeing industry is currently accelerating toward a direction of high efficiency, energy conservation, environmental protection, and integration with digitalization. Disperse dye wash-free digital inkjet dyeing is a revolutionary breakthrough for cleaning and coloring polyester fabric. Based on the solubility parameters and the hot-melt dyeing characteristics of disperse dyes, soft, hard, and functional monomers of acrylate were used as the main body. Moreover, single-vinyl fluorinated polysiloxane and divinyl polysiloxane with low solubility parameters were used as modified monomers. A modified polyacrylate (PFSMA) adhesive containing silicon in the main chain and fluorine silicon in the side chain was prepared via miniemulsion polymerization. Using disperse digital inkjet dyeing of polyester fabric without washing can realize energy saving, emission reduction, and carbon reduction. Results showed that the optimum preparation conditions of PFSMA were as follows: DVFS molecular weight of 957 g/mol and DVFS content of 2.5 wt %. Compared with that of polyacrylate (PA), the glass-transition temperature of PFSMA film decreased, and its water resistance, toughness, and adhesion enhanced. When the PFSMA content in the wash-free disperse red ink was 8 wt %, the color yields of the front and back of the PFSMA jet-dyed polyester fabric were 18.86 and 13.28, respectively. Moreover, the color yield of the front of PFSMA jet-dyed polyester fabric was 39.9% higher than that of the pure liquid disperse red jet-dyed fabric. The simulated fixation rate was 87.9%, approximately 2.9 times higher than that of the PA wash-free jet-dyed fabric. The color fastness to dry rubbing reached level 4 and the color fastness to wet rubbing reached level 3–4, which was one level higher than that of pure liquid disperse red jet-dyed fabrics. The color fastness to soaping reached grade 5 and the color fastness to heat compression reached grades 4–5 and above. The fabric was a little firmer but smoother. The color properties, color fastness, and hand feeling of the PFSMA wash-free jet-dyed polyester fabric exceeded the levels of commercially available adhesives.

Disperse dyes wash-free inkjet-dyeing is one of the important research and development directions to achieve clean dyeing of polyester fabrics. Wash-free binders are needed to be designed with a special molecular structure to achieve good colour yield and fixation during dyeing. Specifically, isophorone diisocyanate and polypropylene glycol were used as the monomers of the hard and soft chain segments of the polymer, respectively, and KH-560 as the capping agent, to prepare a series of end-group cross-linked organosilicon modified waterborne polyurethane (SWPU). It was applied as wash-free binder for the digital inkjet-dyed polyester fabrics. The results showed that, for 2 wt% KH-560 and 40 wt% hard chain segments, the SWPU film had good water resistance, mechanical properties, and adhesion properties, and the best dispersed dye directional effect. With the addition of SWPU in the dye ink of 8 wt%, the front K/S value of the SWPU wash-free digital inkjet-dyes fabric reached 16.86, and the dry/wet rubbing fastness achieved grades 4–5 and 3–4, respectively. Compared with the pure dye inkjet-dyed fabric, its front K/S value increased by 23.9 %, and its dry/wet rubbing fastness improved by grades 1 and 0.5, respectively.

Flammability feature of textiles is a big underlying risk causing fire disasters. The fabrication of reliable fire resistant and quick fire warning fabrics is imperative but challenging. Herein, three types of early fire-warning polyester fabrics, namely, FPP@AM-X, FPP@PM-X and FPP@AX-M1, with good flame retardant and piezoresistive sensing performance were developed by fabricating polyethyleneimine (PEI), ammonium polyphosphate (APP), phytic acid (PA) and MXenes onto phosphorus-containing flame retardant polyethylene terephthalate (FRPET) via polydopamine (PDA) mediated layer-by-layer self-assembly. Owing to the improved thermoelectric properties of MXenes, FPP@A5-M1 exhibited a maximum thermoelectric voltage of 0.59 mV at a temperature difference of 130 °C and can provide an ideal cyclic early fire warning response within 4 s. In addition, due to the synergistic flame retardant effect of MXenes and APP in the coating layer, FPP@A5-M1 could be self-extinguished within 2 s after ignition and the value of peak heat release ratio and total smoke production decreased by 41.9% and 30.4%, respectively. Besides, the MXene-based hybrid coated fabric can detect the movement of human fingers and elbows, illustrating its potential application in piezoresistive tension sensing. This work provides a new route to designing and developing multi-functional and smart fire protection fabrics.
