4D printing of magnetoresponsive soft gripper and phenomenological approach for required magnetical actuation field

Abstract4D printing is the next step in additive manufacturing. Magnetoresponsive materials facilitate the creation of gripping tools through 4D printing, allowing for structural changes in response to external stimuli. In this study, the structural change is manifested as motion, triggered by an external magnetic field. This technology offers significant advantages in medical and industrial applications, including the printing of life-like moving organ models for medical training and the development of actuators for use in explosive environments. Magnetoresponsive materials are programmed with a magnetic profile and actuated by an external magnetic field. A compound of strontium ferrite microparticles $$SrFe_{12}O_{19}$$ S r F e 12 O 19 ($$ \le 20\mu m$$ ≤ 20 μ m ) and an elastic polymer (thermoplastic copolyester) with a Hardness of Shore D 40 was produced. A star-shaped body was programmed and actuated by two permanent magnets, each of $$B_r=1.29 - 1.32T$$ B r = 1.29 - 1.32 T . As there is no analytical approach for calculating the required actuation flux density, one has been developed. The approach is verified experimentally by using a Hall probe. It is appropriate to set the field with a Helmholtz coil, despite the utilization of two permanent magnets. The use of a commercial fused filament fabrication printer for the processing of magnetoresponsive materials has been realized here for the first time. The main contributions are the short time constant (around $$t_a=0.1s$$ t a = 0.1 s ) for actuation and the repeatability (around $$n=200$$ n = 200 actuation cycles) of the motion. The feasibility of multiple diverse reprogramming is a step forward in 4D printing. Hence, the post-print programming and the inhomogeneity of the field limit the ease of the presented method.

Quantitative analysis of the color accuracy and reproducibility in digital textile printing: Discrepancies within color reproduction media

In this study, the overall color reproducibility of a digital textile printing (DTP) process was investigated within a wide range of color gamuts, and the design color factors influencing color reproduction in the initial design stage of DTP were analyzed. During the DTP process, digital image samples, display samples, and fabric samples, each representing 1296 colors, were created. The color reproduction ranges of these samples and the discrepancies in their lightness, chroma, hue, and overall color were analyzed. It was found that the display samples exhibited the widest color reproduction range, particularly in terms of lightness and chroma. In contrast, the fabric samples showed the narrowest color reproduction range. Furthermore, it was shown that color reproducibility was significantly reduced when the medium transitions from display to fabric during the DTP process, with an average overall color difference of 24.34 Δ E*ab being detected between the display and fabric samples. The low color reproducibility of this DTP process was particularly influenced by the K ratio and the L*10 and C*ab,10 values of the initial design. More specifically, the K ratio and the L*10 value of the initial design imparted significant effects on the lightness reproducibility, whereas the C*ab,10 value of the initial design had a significant impact all on the lightness, chroma, hue, and overall color reproducibilities.

REVIEW OF TEXTILE PRINTING: DIFFERENTIATION OF BLOCK, SCREEN & DIGITAL PRINTING

In India is well known for its traditional culture and art features. Hand block printing techniques are practiced in Rajasthan. Hence, the block printing is a slow process. Printing process of desired pattern is defined and repeated. The various styles for block printing are significant of the country in rich culture and heritage. It is a unique of each region will have a different variations of traditional craft. That was crafted for propagating Hindus mythology of depicted folk style story transform of imagination forms of God and goddess in literature. In this article, we will discuss about block printing, the development digital printing and manual of screen printing. The comparison of these three styles of textiles printing. It is a oldest method of art craft. The economics of ink jet printing are the main driver of digital printing technique. The costs of ink jet printing are lower for short run lengths than in traditional screen printing. This switches for longer runs production. Short-run textile printing commissions are the main source of jobs for small to medium scale textile producers in Ghana. And manual screen printing is the main process employed by these small-scale textile printers. These layers of limitations negatively affect the overall outcome of the prints. This is because, the large-scale textile factories in Ghana can print a minimum of 2400 yards due to their machine settings, calibration and running cost to make the least returns. KEYWORDS: Hand block printing, natural dyes, screen printing, techniques, digital printing.

Creativity in textile printing design: An integrative framework in design education

AbstractCreators, creation, and audience are the main pillars of the creative process. This study offers an integrative vision that includes the three main components of the creative process by proposing a seven-stage creativity framework in design education. To bridge the gap between theory and practice, the proposed framework was applied in a major textile design course at Damietta University in Egypt. The paper includes two questionnaire models for the recipients to evaluate the creative outputs and for the students to evaluate the applied framework in general. The study involves an analysis of the experiences and challenges encountered throughout the field application of the proposed framework. The results revealed new dimensions for evaluating creativity and fresh perspectives on the dynamics of the communication process between creators and recipients through their creations/designs. The study's findings could contribute to promoting creativity across the three pillars and advancing design thinking and design education.

3D-Printing Functional Ceramic for One-Step Fabrication of Pd/C Catalytic Reactor

Catalysts are widely used in the chemical industry because of their environmental friendliness and low energy consumption. However, integrated fabrication of catalytic reactors (CRs) remains challenging. In this study, we propose the integrated manufacturing of a palladium-carbon (Pd/C) CR for the first time. The outer shell ink comprises Al2O3 powder and aluminum dihydrogen phosphate (AP), whereas the inner core ink consists of activated carbon powder, AP, and polymethylmethacrylate (PMMA). By integrating with the coaxial 3D printing strategy, the Pd/C CR can be freeform-designed with different core thicknesses, lengths, and shapes (W-type, L-type, and U-type). Based on this, a CR with excellent catalytic properties was further developed by loading palladium (Pd) particles. Typically, the resultant Pd/C CR with a length of 2.5 cm exhibits a catalytic efficiency of up to 97.6% after 60 min. This method of preparing Pd/C CR using coaxial 3D printing combines multimaterial 3D printing, integrated molding, and complex biomimetic structure fabrication. This offers a feasible and cost-effective solution that uses a simple fabrication process.

A novel colored chitosan-modified polystyrene composite dye nanospheres with enhanced coloring properties for binder-free printing

The limited utilization rate of dyes for coloring coupled with the consumption of large quantities of chemical reagents, can result in acute environmental pollution and waste of resources. Herein, in accordance with the electrostatic attraction between electropositivity of chitosan and anionic dyes, a novel type of chitosan-modified cationic polystyrene nanospheres (PSCS) was creatively synthesized, which can be innovatively employed as a special carrier with an adsorption capacity of up to 197.4mg/g for acid dyes. Consequently, a exclusive pigment identified as colored chitosan-modified polystyrene composite dye nanospheres (PSCS(AR9)) was procured. Simultaneously, the binder-free printing was accomplished by leveraging the intrinsic self-curing property of PSCS(AR9) for screen printing of textiles. Additionally, printed fabrics with PSCS(AR9) exhibited superb darkening effect (the K/S value can be increased by 2 times.) in conjunction with significantly improved hand feel in contrast with the conventional printed fabrics. The last but not least, the rubbing fastness of the printed fabrics using PSCS(AR9) can meet demand of the practical application. Therefore, this work may provide an innovative insight for constructing a new type of environmentally friendly and depth-enhanced printed textile.

Research Progress of Printing and Dyeing Wastewater Treatment

In the textile industry, printing and dyeing technology, as an essential technical basis, produces a lot of printing and dyeing wastewater (PDW) that jeopardizes the ecological environment and human health. PDW generally has the characteristics of large discharge, high chromaticity, strong toxicity, strong alkalinity, complex componentization, poor biodegradability, large fluctuations in water quality and quality, and high content of organic pollutants, belonging to the type of industrial wastewater that is difficult to manage. In this paper, the current research progress of PDW treatment technology from the aspects of physical technology, chemical technology, and biological technology are reviewed. In addition, measures to reduce the damage caused by printing and dyeing wastewater from three perspectives: treatment principle, processes, advantages, and disadvantages are discussed, which provides a reference point for the treatment of printing and dyeing wastewater. It is worth noting that the article reviews the ABS system, which is gaining attention as an emerging technology under biological technology. The purpose of this paper is to provide a reference basis for the selection and application of technology, and then promote the innovation and development of printing and dyeing wastewater treatment technology.

A novel quaternary ammonium triethanolamine modified polyester polyether for rapid wetting and penetration pretreatment for digital inkjet dyeing of polyester fabric

Green environmental protection and digitisation are vital for the future development of the textile printing and dyeing industry. Dispersed dye digital inkjet dyeing, as a new technology, enables on-demand low-liquor dyeing and controllable segment dyeing of polyester fabric. This facilitates the transformation, upgrading and sustainable development of the printing and dyeing industry. Due to its inherent hydrophobicity, polyester fabric poses challenges in terms of quick wetting and penetration of ink droplets. To enhance its moisture absorption and rapid wettability, a novel pre-treatment agent, i.e. cationic polyester polyether (CPP), was synthesised via the triethanolamine quaternisation modification of polyester polyether. The wetting and penetration behaviours of ink droplets on the CPP-pre-treated fabric were studied, and the colour performance of CPP-pre-treated dyed fabric was investigated. Results showed that the optimal conditions for CPP synthesis were a DMT to PEG molar ratio of 3:1, a molecular weight of PEG 2000 and a PEG to NAB molar ratio of 1:0.2. At a CPP concentration of 0.3 %o.w.f., the CPP-pre-treated fabric exhibited excellent moisture absorption and rapid wetting with water spreading time of 4 s, wicking height of 9.5 cm/5 min and ink droplet spreading time of 960 ms. Compared with the original inkjet-dyed fabric, the front K/S value of CPP-pre-treated dyed fabric decreased to 17.1 and the back K/S value increased to 16.0. The colour penetration was 93.3 %, which was 13 % higher than that of the original fabric. Thus, CPP pre-treatment of polyester fabric can facilitate complete dyeing of the fabric even within the interior of yarns.

Occurrence and Ecological Risk Assessment of Highly Toxic Halogenated Byproducts during Chlorination Decolorization of Textile Printing and Dyeing Wastewater.

Textile printing and dyeing wastewater is a substantial source of highly toxic halogenated pollutants because of the chlorination decolorization. However, information on the occurrence and fate of the highly toxic halogenated byproducts, which are produced by chlorination decolorization of the textile printing and dyeing wastewater, is very limited. In this study, the occurrence of six categories of halogenated byproducts (haloacetic acids (HAAs), haloacetonitriles (HANs), N-nitrosamines (NAs), trihalomethanes, halogenated ketones, and halonitromethanes) was investigated along the full-scale treatment processes of textile printing and dyeing wastewater treatment plants. Furthermore, the ecological risk of the halogenated byproducts was evaluated. The results showed that the total concentration of halogenated byproducts increased significantly after chlorination. Large amounts of HAAs (average 122.1 μg/L), HANs (average 80.9 μg/L), THMs (average 48.3 μg/L), and NAs (average 2314.3 ng/L) were found in the chlorinated textile wastewater, and the results showed that the generations of HANs and NAs were positively correlated with the BIX and β/α index, indicating that the HANs and NAs might form from the microbial metabolites. In addition, HAAs and HANs exhibited high ecological risk quotients (>1), suggesting their high potential ecological risk. The results also demonstrated that most halogenated byproducts could be effectively removed by reverse osmosis treatment processes except NAs, with a lower removal rate of 18%. This study is believed to provide an important theoretical basis for controlling and reducing the ecological risks of halogenated byproducts in textile printing and dyeing wastewater effluents.

Direct Printing of Disperse Dye Inks to Polyester Fabrics without Chemical Pretreatment.

Direct inkjet digital printing is a relatively green and environmentally friendly textile printing method with a wide range of applications in the textile printing and dyeing industry. However, pretreatment of the fabric is required before digital printing, which will generate certain energy consumption and wastewater. In this study, a digital direct inkjet printing method was developed to improve the printing accuracy of poly(ethylene terephthalate) (PET) fabrics without any pretreatment. A kind of direct inkjet printing ink was prepared by the response change in temperature viscosity. The increase in viscosity inhibits ink bleeding on the fabric, thereby improving printing accuracy. A thermosensitive direct inkjet printing disperse dye ink was prepared by adding cetyltrimethylammonium bromide (CTAB) and 3-methylsalicylic acid (3MS) to the ink. By evaluating the changes in the ink particle size, shear viscosity, and temperature viscosity, it was found that this thermosensitive ink has an excellent average particle size and special changes in viscosity with increasing temperature. When this heat-sensitive ink is printed on a polyester fabric, the fabric does not need pretreatment to improve the clarity of printing, and the printed fabric has satisfactory color fastness to friction and washing.

Environmental Sustainability Analysis of Rotary-Screen Printing and Digital Textile Printing

Worldwide concern regarding the need for more sustainable textile supply chain prompted emphasis on innovation in the coloration process, often considered the most problematic segment of the supply chain. Digital textile printing, an emerging coloration technology, has the potential to improve sustainability significantly. This study undertakes an environmental sustainability analysis that compares the impacts of rotary-screen printing, the traditional, more established printing method, and digital textile printing. Researchers partnered with Creditex S.A.A., a vertically integrated textile company from Peru, to perform the research in a realistic factory setting. Creditex printed a 16-color design for an order of 1000m cotton fabric with reactive dye occupying both rotary-screen printing and digital textile printing and collected environmental impact data throughout the production process, including consumption, usage, and wastage. The findings suggest that digital textile printing is favorable to rotary-screen printing in terms of environmental sustainability impacts within the research context.

This review focuses on the transformative applications of deep learning and artificial intelligence in textile dyeing, printing, and finishing. In textile dyeing, the topics span color prediction, color-based classification, dyeing recipe prediction, dyeing pattern recognition, and the nuanced domain of color fabric defect detection. In textile printing, applications of artificial intelligence and machine learning center around pattern detection in printed fabrics, the generation of novel patterns, and the critical task of detecting defects in printed textiles. In textile finishing the prediction of fabric thermosetting parameters is discussed. Artificial neural networks, diverse convolutional neural network variations like AlexNet, traditional machine learning approaches including support vector regression, principal component analysis, XGBoost, and generative artificial intelligence such as generative adversarial networks, as well as genetic algorithms all find application in this multifaceted exploration. At its core, the interest to use these methodologies is because of the need to minimize repetitive and time-consuming manual tasks, curtail prototyping costs, and promote process automation. The review unravels a plethora of innovative architectures and frameworks, each tailored to address specific challenges. However, a persistent hurdle looms – the scarcity of data, which remains a significant impediment. While unveiling a collection of research findings, the review also spotlights the inherent challenges in implementing artificial intelligence solutions in the textile dyeing and printing domain.

Insight into simultaneous urea hydrolysis and total nitrogen removal in textile printing wastewater: Focus on the impact of sodium sulfate salinity

The textile printing industry discharges large volumes of effluent containing high concentrations of urea and nitrogenous compounds. Anoxic-oxic (AO) treatment is a promising method for treating printing wastewater. However, the effect of sodium sulfate (Na2SO4) salinity on the urea hydrolysis and nitrogen removal simultaneously in the AO process has received little attention. In this study, five batch reactors were used to treat synthetic printing wastewater with high urea and nitrogen concentrations. A strategy was applied to increase the Na2SO4 concentration from 0 to 19 g/L in the anoxic stage of each reactor. The effect of Na2SO4 on urea hydrolysis, total nitrogen removal and COD removal, sludge characteristics, and bacterial community structure were investigated. The findings showed that urea hydrolysis increased with increasing Na2SO4 concentration. The main mechanism of urea removal was intracellular hydrolysis, with a urea removal efficiency (URE%) of approximately 98% in all batch reactors. In addition, under the stress of Na2SO4, the total nitrogen and COD removal performances were partially inhibited. The most significant removal performances after AO treatment were observed at 0 g/L Na2SO4, with nitrogen and COD removal efficiencies of 88% and 95%, respectively. When Na2SO4 concentration reached 19 g/L, the sludge settling performance and compactness were enhanced. The extracellular polymeric substance (EPS) components in the sludge were dependent on their ability of removing organics. Bacterial community diversity analysis revealed that the enrichment of the Proteobacteria, Firmicutes, and Gemmatimonadota phyla in the anoxic stages of batch reactors was related to intracellular urea hydrolysis. Bacteriodota and Chloroflexi were responsible for total nitrogen removal in all anoxic and oxic stages. This research will develop the understanding of Na2SO4 salinity impact on simultaneous urea hydrolysis and nitrogen removal during AO treatment process.

Comparison of FDM and SLA printing on woven fabrics

Possibilities to perform 3D printing directly on textile fabrics have been investigated intensively during the last decade. Usually, fused deposition modeling (FDM) printing with often inexpensive 3D printers is applied in these experiments. Several studies revealed the influence of textile fabrics, FDM polymers and printing parameters, indicating that not all combinations of fabrics and printing materials are suitable for this task. Recently, first approaches to use stereolithography (SLA) or PolyJet Modeling (PJM) directly on textile fabrics have been reported. Here, the first comparison of the adhesion forces reached by FDM and SLA printing on different woven fabrics is shown, revealing significantly better adhesion for SLA printing.

Innovative integration of chitosan biopolymer for felt-free woolen fabric: A synergistic approach with digital textile printing

Wool, renowned for its ancient legacy and unique attributes, is a prized textile fiber with versatile applications in various domains. However, the susceptibility to shrinkage due to the scaly structure of overlapping cells (scales) in the cuticle poses a challenge, prompting the widespread adoption of chlorination to enhance resistance to felting and shrinkage. This research explores the potential of chitosan biopolymer as an effective anti-felting agent and enhancer of wool dyeability. With its non-toxic, biocompatible, and biodegradable properties, chitosan is a promising substitute for various textile finishes. Recent innovations include chitosan’s contribution to improving the digital printing process, particularly in enhancing color strength and sharpness on cotton fabric. Identifying a research gap in exploring the synergistic potential of chitosan for anti-felting, this study introduces an alkaline hydrogen peroxide pre-treatment to enhance chitosan absorption through the pad-dry-cure method. Chitosan, acting as a binder, is strategically applied in the pre-treatment to fix pigments with reactive inks during inkjet printing. Critical process parameters, such as chitosan concentration, curing temperature, and time, were optimized for area shrinkage (%) to achieve a felt-free property for wool. Subsequent optimization focuses on color strength, print sharpness, and washing durability of digitally printed patterns. The results obtained from this research were quite promising in terms of K/S value, wettability, pilling behavior, tensile strength, edge sharpness, washing fastness, and fabric shrinkage resistance.

Preparation of ZIF-67 derived Co3O4 composite non-homogeneous catalysts with cerium oxide for the efficient degradation of Rhodamine B

The textile printing and dyeing industry produces a significant amount of wastewater, which is challenging to degrade due to its high organic concentration, complex composition, and high chromaticity. This type of wastewater is considered one of the most difficult to treat. In recent years, advanced catalytic oxidation based on sulfate radicals (SO4−) can efficiently degrade printing and dyeing wastewater. Seeking non-homogeneous catalysts for the activation of the radicals is the key problem to be solved nowadays. In this study, Ce/Co-ZIF precursor was obtained by stirring and precipitation, and the ZIF-67-derived non-homogeneous catalyst of Co3O4 and CeO2 was successfully synthesised by calcination for the efficient catalytic degradation of Rhodamine B (RhB) dye. The morphological structure and elemental distribution of the non-homogeneous catalysts were observed using SEM, TEM, XRD, and XPS. Additionally, the factors that affect the degradation of RhB dye were investigated. These factors were adjusted individually, from CeO₂ loading, pH, material dosing, to persulfate (PS) dosing, and it was determined that the rate of RhB degradation also increased from the initial 92 % to a value of 97.1 %. It was found that under the optimal conditions of a CeO2 loading percentage of 0.44, pH of 7, and composite material and potassium persulfate dosage of 5 mg and 0.4 g/L, respectively, the catalytic system achieved a degradation rate of 97.5 % of RhB dye within 30 min. Then the non-homogeneous catalyst could still maintain the good catalytic degradation effect after 5 cycles of regeneration experiments. Therefore, the ZIF-Co3O4@CeO2 non-homogeneous catalyst has a good potential for wastewater treatment and provides a new way for the application of high performance catalysts in the future.

Study on Methylene Blue Adsorption Properties of Biochar/Montmorillonite Composites

The textile printing and dyeing industry, as one of the important pillars of the global economy, has become an environmental problem that needs to be solved because of the increasingly serious pollution of dye wastewater generated during its production process. Dye wastewater not only contains high concentrations of organic dyes, but also often accompanied by heavy metal ions, additives and salts and other pollutants, if discharged directly without effective treatment, will seriously pollute the water body, destroying the ecological balance, and affecting the survival and health of human beings and aquatic organisms. In order to deal with the problems of serious pollution, large discharge and high cost of dye wastewater, it is necessary to develop an efficient, economic and environmentally friendly wastewater treatment system. It is particularly important to develop efficient, economical and environmentally friendly wastewater treatment technologies. Adsorption is considered as a promising method for wastewater treatment. In this study, we focused on the development of new and efficient adsorbent materials. Taking methylene blue, a typical dye, as an example, we skillfully composited modified biochar with montmorillonite, a natural mineral material, through pyrolysis and intercalation strategies, and conducted in-depth investigations on the effects of the composites on the adsorption of methylene blue in water, the factors affecting the regeneration performance of the adsorbents, and the thermodynamic characteristics of the adsorption. The effect of the composite material on the adsorption of methylene blue in water, the factors affecting the regeneration performance of the adsorbent and the adsorption thermodynamic characteristics were investigated in depth, with a view to providing certain theoretical and practical references for the effective treatment of dye wastewater.
