Fluorinated polyhedral oligomeric silsesquioxane (F-POSS) is one of the most popular candidates at present for superhydrophobic coating. Because of its ultralow surface energy, F-POSS has usually been dissolved with expensive fluoro-solvents, and the melting temperature of F-POSS is not high (122–140 °C), which will cause its loss during use. So trying to polymerize/crosslink F-POSS molecules and/or directly graft F-POSS to substrate is important. In this work, we report the SI-eATRP grafting of methacryl POSS (MA-POSS) on cotton and the subsequent amine catalyzed thiol-methacrylate Michael addition reaction of poly(MA-POSS) with 1H, 1H, 2H, 2H-perfluorododecyl-1-thiol (PFDT) for the fabrication of a durable poly(MA-POSS)-PFDT coating. The cotton fabric coated with poly(MA-POSS) was nearly superhydrophobic after 4 h of SI-eATRP process under potentiostatic condition of −0.40 V. Although the water contact angle (WCA) was ~148°, water droplets tended to adhere to the cotton fabric surface even when the fabric was turned upside down. After fluorination, WCA was increased to ~160°, and water drops could slide off when the fabric was slightly tilted. The sliding angle (SA) was ~10°. The as-prepared poly(MA-POSS)-PFDT coating was durable against repeated washing and physical abrasion. After 30 accelerated washing cycles (equals to 150 home laundering cycles), the coated fabric still showed superhydrophobicity. After 800 abrasion cycles over sandpaper, the WCA was still as high as 149°. In addition, the coated fabric had self-healing ability and could restore its superhydrophobicity after plasma etching through heat treatment. After 10 cycles of plasma etching and heat-induced healing process, the WCA of the coated fabric kept at ~154°. Such a durable superhydrophobic fabric coating may find applications in the development of functional clothing for a variety of purposes.

Research approaches on the use of ecotechnologies like ozone assisted processes for the decolorization of textiles are being explored as against the conventional alkaline reductive process for the color stripping of the cotton textiles. The evaluation of these ecotechnologies must be performed to assess the environmental impacts. Partial “gate to gate” Life Cycle Assessment (LCA) was implemented to study the ozone based decolorization process of the reactive dyed cotton textiles. Experiments were performed to determine input and output data flows for decolorization treatment of reactive dyed cotton textile using the ozonation process. The functional unit was defined as “treatment of 40 g of reactive dyed cotton fabric to achieve more than 94% color stripping”. Generic and specific data bases were also used to determine flows, and International Life Cycle Data system (ILCD) method was selected to convert all flows into environmental impacts. The impact category “Water resource depletion” is the highest for all the ozonation processes as it has the greatest relative value after normalization amongst all the impact indicators. Electricity and Oxygen formation were found to be the major contributors to the environmental impacts. New experimental conditions have been studied to optimize the impacts.

This study has attempted to use the click chemistry reaction, wherein vinyl trimethoxysilane (VTMS) and mercaptan react under ultraviolet (UV) light to produce a hydrophobic reagent and hydrolyse under appropriate conditions. The hydrolysed product is dehydrated and condensed with cotton fabric at high temperatures to obtain superhydrophobicity. Herein, the effect of different carbon chain length reactants on the hydrophobicity of cotton fabric was discussed, and it was found that different products showed different hydrophobicity. The static contact angle was 159°, and the sliding angle was 7.2°. The chemical structure and morphological changes of the surface of the fiber after the modification were characterised using Fourier-transform infrared, scanning electron microscopy, X-ray photoelectron spectroscopy, and energy-dispersive spectroscopy. The results showed that the surface of the modified cotton fiber was wrapped by a micron-level polymer resistant to UV, acids, acetone solvents, and water washing. Thus, this novel preparation approach developed a superhydrophobic cotton with multiple functions, such as self-cleaning and oil–water separation and has promising applications in complex fields.

Pilling is a common and unresolved problem in knitted fabrics, especially for the cellulose fiber blended fabrics, which not only causes an unattractive appearance and an uncomfortable handle, but also reduces the added value of the products. In this study, four different kinds of knitted fabrics were treated with 2,4,6-trichloropyrimidine (TLP) alkaline emulsion by dipping and pad–dry–cure modification processes. The surface morphology and chemical structure of original and treated fabrics were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The anti-pilling performance, thermal properties, physical and mechanical properties and color features of treated fabrics were also evaluated. The results indicated that TLP was successfully covalently crosslinked onto the surface of the cellulose fibers. The dipping process resulted in a better anti-pilling property than that of the pad–dry–cure process, and both treatments could bring about an excellent anti-pilling property and outstanding laundering durability. A pilling grade of 4.5 was achieved for the treated polyester/viscose (T/V) fabric with the dipping process even after 20 washing cycles. In addition, the treated fabrics displayed an enhanced antistatic property and still maintained a soft handle. Besides, the bursting strength and air permeability of treated samples were found to have a slight deterioration, while no apparent differences were found in the color parameters and colorfastness of dyed fabrics. The above results demonstrate that 2,4,6-trichloropyrimidine has the potential application prospect in the functional finishing and home-caring of textiles.

We report an improved printing ink of polyester fabric employed in the production process of inkjet printing. In the design of printing ink, the solubility parameters of reagent and HLB value of surfactant are used to prepare the ink. This production process does not require the pretreatment of polyester fabric to directly carry out inkjet printing. By regulating the intermolecular force relationship between the components of ink and the compactness of ink microstructure, it can improve the diffusion of ink on the surface of polyester fabric. The low-field NMR (LF-NMR) revealed the correlation between the fluidity and transverse relaxation time of main reagent solutions and ink. The test results show that there are three types of water: hydrogen-bond water, bound water and free water in main reagent solutions and ink. The LF-NMR was also used to investigate the relationship between ink viscosity and transverse relaxation time. It was observed that the transverse relaxation time (1084.4–410.3 m s, peak maximum time of T22) of ink decreases with the increase of ink viscosity (2.3–11.1 mPa s). The viscosity and transverse relaxation time of ink is associated with the intermolecular force and the compactness of microstructure of ink. The formation of ink droplets was systematically observed by the ink droplet observation instrument. When the surface tension and viscosity of ink are 32.2–37.4 mN/m and 2.3–8.8 mPa s, respectively, the ink can be smoothly inkjet. With the increase of viscosity of the ink (2.3–8.8 mPa s), the sharpness of printing pattern is obviously improved, and the change rate of the line width (W) of the printing pattern is reduced from 52.6% to 4.4%. The microstructure of ink can bound the solvent of the ink, reduce the fluidity of the solvent, and improve the sharpness of the printing pattern. The test results of KES style and color fastness of the printed fabric show that the printed fabric fully meets the wearing requirements. Compared with other the soap liquid of printed fabric, the soap liquid of printed fabric RD-2B has strong UV absorption strength, the soap liquid RD-2B has a higher dye content. The characterization results of volatile organic compounds (VOC) in ink SDS R7 is 17.0 g/kg. The chemical oxygen demand (COD) values of printed fabrics RD-2B and SDS R7 are 150.0 and 102.0 mg/L, and the biochemical oxygen demand (BOD5) values of printed fabrics RD-2B and SDS R7 are 130.0 and 97.7 mg/L. Compared with the common polyester fabric printing ink (ink RD-2B), the prepared ink has the characteristics of environmental protection, high production efficiency and low energy consumption, which has the potential to achieve green printing.

A robust superhydrophobic fabric coating was fabricated on cotton fabric under UV light, which was achieved by convenient surface modification with mercaptopropyltriethoxysilane, tetramethyltetravinylcyclotetrasiloxane, and octadecyl mercaptan. The modification of cotton fabric with 3-mercaptopropyltriethoxysilane introduces reactive mercapto groups, after which 2,4,6,8-tetramethyltetravinylcyclotetrasiloxane reacts with mercapto groups, and octadecyl mercaptan provides microscale roughness. The nonpolar carbon chains of thiol cause the cotton to have a low surface energy. As reported, the combination of microscale roughness with low surface energy has a superhydrophobic effect on cotton, which leads to a high contact angle of 161.8° and sliding angle of 8°. Infrared spectroscopy, XPS, and SEM tests were used to characterize the chemical structure and morphological changes of the surface of cotton fabric before and after click reaction. The fabric after click reaction exhibited an oil–water mixture separation ability owing to its superhydrophobicity. Thus, the finished fabric could be used in the oil–water separation field. Importantly, the superhydrophobic textile displays resistance to laundering, mechanical abrasion, strong acidic and alkaline environments, and UV irradiation. We hope that this study can broaden the real-life applications of cotton fabric.

Grape skins and seeds rich in polyphenolic compounds are low-value byproducts from the winemaking. The valorization of such byproducts is of great significance. This work presented a novel application of grape seed proanthocyanidins (GSPs) in the dyeing and flame-retardant and antibacterial treatment of silk. The study on adsorption isotherms revealed that multiple interactions occurred between GSPs and silk, including electrovalent bonding, hydrogen bonding and van der Waals forces. The color depth of silk mainly depended on temperature and GSPs concentration. Dyed silk had acceptable color fastness to washing, rubbing and perspiration. Postmordanting could improve light fastness. Changes in the tensile strength and flexural rigidity of dyed silk were in an acceptable range. A low concentration of GSPs imparted durable antibacterial function to silk. The biggest highlight of this study was the improved flame retardancy of silk caused by GSPs dyeing. GSPs increased the thermal stability and charring ability of silk at high temperatures, and their flame-retardant action worked in the solid phase. Mordanting had no substantial impact on the flame-retardant and antibacterial functions of dyed silk. The present research reveals that the valorization of GSPs for silk processing is feasible.

Cotton has the shortcomings of having no antibacterial, antioxidant and ultraviolet (UV) protection properties, which are of great importance for health protection purposes. In the present study, grape seed extract (GSE) mainly composed of proanthocyanins (tannins) was employed to simultaneously import pale colors and the three aforementioned functions to cotton fabric. The tests on the application conditions of GSE showed that pH and GSE concentration had great impact on the color depth of cotton fabric, and the color hue of dyed fabric could be controlled in the absence of pH regulators due to the weakly acidic nature of GSE solution. The fabric dyed with 10%owf (on the weight of fabric) GSE exhibited an excellent inhibition effect towards Escherichia coli, whereas the one dyed with 20%owf GSE had high antioxidant activity of 97%. The fabric dyed with 5%owf GSE offered excellent UV protection. This study reveals that GSE can be used as a functional finishing agent for health protection in cotton textiles in addition to coloration capability.

The water retention of printing inks is of the utmost importance. According to low -field nuclear magnetic resonance (LF-NMR) to detect the behavior of polyols and water, polyols with excellent water retention performance can be selected quickly. The water retention of disperse ink is closely related to the intramolecular/intermolecular forces of each component in the disperse ink. The relationship between each component of the ink is revealed by LF-NMR. The water retention of ink was also evaluated by LF-NMR. Therefore, the LF-NMR was able to design ink formulation and evaluate ink quality. Compared with NNO and TD-1109, Surfynol CT-136 had a higher grinding efficiency for disperse dyes. The physicochemical properties of disperse ink was evaluated to meet the requirements of inkjet printing ink. The rheological properties of the disperse inks were characterized by rotary rheometer, which were confirmed as Newtonian fluid; The quality of the ink-jet printing pattern is closely related to the ink jet performance. The formation process of the ink droplet and the parameters of the ink droplets were observed by the ink droplet observer. The ink has excellent jetting properties and a high-quality print pattern at an appropriate viscosity (3.1 mPa.s) and surface tension (34.2 mN/m). The excellent affinity between NVP/VA copolymer (NVP/VA64) and disperse dyes was confirmed by ultraviolet spectrophotometer (UV spectrophotometer). The scanning electron microscope (SEM) images of printed fabrics show that there is a film on the surface. The NVP/VA copolymer can be used as a carrier for disperse dye to improve the fixation and fastness of disperse dye in polyester fabrics.

Polyamide (PA) fiber is the second largest synthetic fiber, and extensively applied in underwear, outerwear, sports/leisure wear and decorative fabrics. However, PA textiles have poor wearing comfort resulting from their inherent hydrophobicity, and do not possess antibacterial function which is vital for preventing bacterial infections. To address these issues, this study employed polylysine (PLL) biomolecule to fabricate the hydrophilic and antibacterial surface on PA fabric by a dip coating technique. The Schiff base reaction between the aldehyde groups of glutaraldehyde and the amino groups of PLL and PA fiber was utilized to increase washing resistance. The effects of the dip coating conditions of PLL on the hydrophilicity of PA fabric were studied by the wetting time of water droplet. The hydrophilicity imparted to PA fabric by PLL coating was further confirmed by water contact angle, moisture adsorption and capillary effect tests. The PLL coated fabric exhibited excellent hydrophilic and antibacterial properties with good washing durability. The functional surface of the PLL coated fabric was proved by scanning electron microscope, X-ray photoelectron spectroscopy, and charge effect. The present research suggests that PLL biomolecule can be used as a surface coating agent for simultaneously imparting hydrophilic and antibacterial functions to PA fiber.

Dispersion of iron was achieved on waste silk fibers (wSF) after grafting of polydopamine (PDA). The catalytic activity of the resulting material (wSF-DA/Fe) was investigated in Fenton-like removal of toxic aromatic dyes (Methylene Blue, Cationic Violet X-5BLN, and Reactive Orange GRN) water. The dye removal yield reached 98%, 99%, and 98% in 10–40 min for Methylene Blue, Cationic Violet X-5BLN, and Reactive Orange GRN, respectively. The catalytic activity was explained in terms of the effects of temperature, dyes, and electrolytes. In addition, the kinetic study showed that the removal of dyes followed pseudo-1st order adsorption kinetics. These findings allow envisaging the preparation of fiber-based catalysts for potential uses in environmental and green chemistry.

Traditional flame retardants (FRs) for textiles are limited by toxicity, environmental persistence and bioaccumulation. There is an urgent need to develop environmentally benign FRs. For this purpose, the combination of tannic acid (TA, a specific form of hydrolysable tannin) and ferrous ion was applied to simultaneously impart durable FR and antibacterial functions to silk fabric. A ternary TA-ferrous ion-silk complex was fabricated by adsorption of TA on silk followed by mordanting with ferrous salt. After treated with 20% TA (on the weight of fabric) and 2 g/L ferrous sulfate, silk fabric exhibited an obvious increase in limiting oxygen index from 23.6% to 27.5%, a significant decrease in damaged length from 30.0 to 11.2 cm after vertical burning, and a significant increase in antibacterial rate from 22% to 95%. Even after 20 washes, the treated fabric still had the same FR ability as the unwashed one, and an antibacterial rate of above 90%, exhibiting excellent washing durability. The high thermal stability of the treated fabric in nitrogen indicated the formation of a ternary TA-ferrous ion-silk complex which was responsible for excellent washing durability. The observation on the morphological structure of charred products from vertical burning revealed the good charring capability of the treated fabric which contributed to enhanced FR behavior. This research proposes an eco-friendly FR treatment for silk and a novel application of hydrolysable tannins in the FR modification of textiles.

Five potentially environmentally friendly and light-stable hemicyanine dyes were designed based on integrated consideration of photo, environmental, and computational chemistry as well as textile applications. Two of them were synthesized and applied in dyeing polyacrylonitrile (PAN), cotton, and nylon fabrics, and demonstrated the desired properties speculated by the programs. The computer-assisted analytical processes includes estimation of the maximum absorption and emission wavelengths, aquatic environmental toxicity, affinity to fibers, and photo-stability. This procedure could effectively narrow down discovery of new potential dye structures, greatly reduce and prevent complex and expensive preparation processes, and significantly improve the development efficiency of novel environmentally friendly dyes.

In this study, we report a simple method for preparing superhydrophobic cotton fabrics via the thiol-ene click reaction. We modified the cotton fabric using vinyl trimethoxysilane (VTMS), which adds more reactive vinyl groups to it. The thiol-ene click chemistry reaction under UV irradiation showed that the functionalised fabric exhibited excellent superhydrophobicity, with a water contact angle of 156.5° and sliding angle of 8°. The morphology and constitution of the superhydrophobic cotton fabric were characterised using scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS). The results show that coating the surface of the cotton fabric with polymer films increased its surface roughness and lowered its surface energy. The treated fabric can be used for the separation of oil–water mixtures owing to its superhydrophobicity. Moreover, different tests showed that it retained its high hydrophobicity even under harsh conditions. Superhydrophobic cotton fabrics have potential applications in oil–water separation, and its simple preparation method gives it broad application prospects.

Silk fibroin (SF) is a natural material with good biocompatibility and excellent mechanical properties, which are complementary to graphene with ultrahigh electrical conductivity. In this study, to maximally combine graphene and silk fibroin, a well-dispersed silk fibroin/graphene suspension was successfully prepared in a simple and effective way. Then we prepared a flexible conductive SF/graphene film with a minimum resistance of 72.1 ± 4.7 Ω/sq by the casting method. It was found that the electrical conductivity of the SF/graphene film was related to the water content of the film, and the variation was more than 200 times. Therefore, it will play an important role in the field of humidity sensors. It also has excellent mechanical properties in both wet and dry states. These unique features make this material a promising future in the fields of biomedical applications, wearable sensors, and implantable internal sensors.

The present research focused on the extraction of the functional components of tea stem waste generated in tea processing and their application for the simultaneous coloration and flame retardant and bioactive functionalization of silk. The extraction was carried out in alkaline condition, which yielded more functional dyes than those in water and 75% aqueous ethanol. The oxidative polymerization of polyphenols during the alkaline extraction resulted in the formation of macromolecular polyphenols which could impart flame retardancy to silk. The extracts exhibited the highest uptake by silk when applied at pH 3 and 90 oC using an adsorption technique, and had good washing fastness on silk but poor perspiration and wet rubbing fastness. The inadequate fastness characteristics were evidently ameliorated by post-mordanting with metal salts. As adequate tea stem extract was used, dyed silk exhibited good flame retardant, antibacterial and antioxidant behaviors. Post-mordanting further enhanced flame retardancy but negatively affected antibacterial and antioxidant behaviors. The inhibition of tea stem extract on silk burning was unexpectedly found for the first time. The increased charring ability of silk caused by this process was responsible for its enhanced flame retardancy. This work suggests novel approaches to reuse of tea stem waste and simultaneous coloration and functionalization of silk.

Cotton fabric, a natural cellulose material, is widely used in the textile industry for its excellent properties. However, its application in some fields are seriously restricted because of its poor antipilling behavior. In this study, cotton fabrics were modified with 2,4,6-trichloropyrimidine (TLP), 2,4-dichloro-5-methoxypyrimidine (DMP), and 2-amino-4,6-dichloropyridine (ADP). The surface morphology and chemical structure of the modified cotton fabric were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Furthermore, the antipilling behavior, dyeing properties, thermal properties, and mechanical properties of modified cotton fabric were evaluated. The results showed that chloropyrimidine compounds were successfully grafted onto the surface of the cotton fabric, leading to excellent and durable antipilling activity of grade 3–4 even after 10 washes. Moreover, compared with control cotton fabric, the heat release rate (HRR) and total heat release (THR) of TLP-modified cotton fabric decreased to 173.2 W/g (42.3% reduction) and 11.3 KJ/g (13.7% reduction), respectively. In addition, the increased K/S value of modified cotton fabrics dyed with reactive dyes indicated that the modification can enhance the dyability of cotton fabric. This technique provides a simple and versatile method for improving the antipilling behavior of cellulosic materials and supports further preparation of functional textiles.

The study aims to investigate the effect of additives (poly (vinyl pyrrolidone) PVP, glycerol, ethylene glycol) on the performances of disperse water-based inks for ink-jet printing and how such additives interact with water. This should help into design suitable inks for textile printing by ink-jet printing, in particular for synthetic fibers such as polyester fabrics. Thirteen kinds of inks were prepared, and the glycerol content was replaced by water and PVP (K15, K30, K60), and the solubility parameter of the additive was calculated by the group contribution method. Low field nuclear magnetic resonance (LF-NMR) reveals the existence of bound water, intra-microstructure water, and extra-microstructure water in the ink, and the intra-microstructure water is entrapped inside the micro-structure formed by additives, mainly due to the presence of PVP. The optimal ink (Y5K30) has a low linewidth relative change (0.4%) and excellent sharpness. The reason is the existence of microstructure in ink, which reduces the mobility of solvent in ink and the diffusion of ink on fabric. PVP and disperse dyes have a strong affinity and help to improve the color depth and color fastness of the fabric.

Three novel 2,4-dihydroxybenzophenone UV-absorber-containing compounds, 2,4-dihydroxybenzophenone-conjugated G0-PAMAM dendrimer-curcumin (D4), 2,4-dihydroxybenzophenone-conjugated G1-PAMAM dendrimer-curcumin (D5) and 2,4-dihydroxybenzophenone-conjugated G2-PAMAM dendrimer-curcumin (D6) were synthesized from reactant cyanuric chloride via coupling to PAMAM (G0,G1,G2) as well as curcumin. Chemical structures of newly prepared materials were proved by means of elemental analysis, FTIR, 1HNMR, 13CNMR, UV–vis and DSC techniques. The spectral features of D4-D6 were studied in comparison with those of unmodified curcumin. The novel 2,4-dihydroxybenzophenone UV-absorber-containing compounds exhibited a narrow peak at 420–440 nm with high molar extinction coefficient. To study their dyeing features and the obtainable color gamut, synthesized compounds were used in the high temperature dyeing of polyethylene terephthalate (PET) fabrics and their light fastness was also evaluated. The outcomes revealed that the building-up and light fastness of new dyes were considerably developed.

Polyamide fiber has the requirements for antioxidant and antibacterial properties when applied to produce functional textiles for heath care purposes. In this work, three natural flavonoids (baicalin, quercetin, and rutin) were used to simultaneously impart antioxidant and antibacterial functions to polyamide fiber using an adsorption technology. The relations of the chemical structures of flavonoids with their adsorption capability, adsorption mechanisms, and antioxidant and antibacterial activities were discussed. The Langmuir–Nernst adsorption model fitted the adsorption isotherms of the three flavonoids well. The adsorption kinetics of the three flavonoids conformed to the pseudo second-order kinetic model. Quercetin exhibited the highest affinity and adsorption capability, and imparted the highest antioxidant and antibacterial activities to polyamide fiber; and moreover, its antioxidant and antibacterial functions had good washing durability. This study demonstrates that the treatment using natural flavonoids is an effective way to exhance the health care functions of polyamide fiber.
