dc.title: Investigating cross-linking of sodium alginate and calcium chloride for use in a microfluidic kit dc.contributor.author: Silver, Katie; Laird, Katie; Shen, Jinsong; Qutachi, Omar; Davies, Angela dc.description.abstract: Background: Standardised microcapsules have many potential medical uses, for example drug delivery, diagnostics and NGS. This project in particular will be looking at encapsulating essential oils to provide antimicrobial properties to materials such as healthcare uses and textiles. A novel smart microfluidic control system (Fluigent, Fr) will be used to standardise the materials, size (95-160渭m) and production rate of the microcapsules produced. However, this system recommends oil surfactant to result in a water-in-oil microbead. This project seeks to investigate replacing this oil phase with sodium alginate and a cross-linking agent such as calcium chloride (CaCl2). It is paramount that instantaneous polymerisation causing clogging of the microscopic fluidic chamber does not occur, however still producing strong and reliable gels to be used as an encapsulant. Although this has been achieved in research through using self-made and 3D printed models, there has yet been a standard protocol in which researchers can produce monodispersed beads using their own core materials with the kit. Methods: Testing a range of sodium alginate concentrations from 0.5% - 3% against CaCl2 of 5mM to 20mM using the Luer lock syringe method to determine how many cycles and minutes it takes for a gel to form. The endpoint was when a thicker gel was apparent, but not solid. Results: It was found that CaCl2 in concentrations of 15mM or lower prolonged the gelation of sodium alginate concentrations of 1 鈥� 1.5% to around 3 鈥� 8 minutes. Further investigation using a range of ratios with these concentrations is currently underway. Conclusions: This study can provide a set of cross-linking timings ranging from seconds to minutes, making it possible to use in a microfluidic kit without setting and blocking the system.

dc.title: Peroxidase-catalysed coloration for fabric design with colour patterns dc.contributor.author: Netithammakorn, Nalinee; Smith, Edward; Lerpiniere, Claire; Shen, Jinsong dc.description.abstract: Biotechnology using enzymes has been explored in textile wet processing for potential of reducing chemical, energy and water consumption, due to being highly specific biocatalysts that can operate under mild temperature and neutral pH conditions. The current research study contributes to an understanding of the use of the enzyme peroxidase for textile coloration of wool fabrics as an alternative coloration method to using conventional dyestuff. Peroxidases, belonging to the enzyme group of oxidoreductases, can catalyse oxidation of a wide range of colourless simple aromatic compounds as precursors to form polymeric colourants. This enzymatic coloration can be successfully applied to in-situ dyeing of wool fabrics at a low temperature through peroxidase catalysis of various precursors to achieve a diverse colour palette. It was found that peroxidase can be active over a broad range of pH values to catalyse the synthesis of colourants, resulting in successful coloration of wool fabrics with various colour shades. Peroxidase catalysed coloration of wool fabrics has the potential not only as an alternative coloration process, but also by saving energy and preventing wool fibre damage. To explore the potential of enzymatic coloration for fabric design, colour patterns on fabrics were created using techniques including tie-dyeing and embroidery. Jacquard woven fabrics with different fibre yarns can also show unique colour patterns from subsequent enzymatic dyeing.
dc.title: Development of enzyme-based biotechnology to support the wool industry transition to a circular system dc.contributor.author: Shen, Jinsong dc.description.abstract: There are increasing demands for textile materials to be sustainable and recyclable for circularity, and a reduction of negative impacts to the environment. Enzyme-based biotechnology could provide an alternative solution to improve wool fibre performance and limit the impact of wool processing on the environment. The current research explored biotechnology for in-situ enzyme-catalysed coloration of wool, and for recycling and reuse of low value wool and/or post-manufacture waste wool feedstocks to extract wool polypeptides for their applications. The extracted polypeptides were utilised for grafting on virgin wool fabrics to improve shrink-resist property of wool fabrics during washing and remain recyclable due to no added on chemical additives or synthetic polymer. Results obtained are being further developed within an ongoing BBSRC-funded project ENZBIOTEX (BB/X011623/1) for developing enzyme-based biotechnology for fibre-to-fibre recycling. Post-consumer/manufacture or waste wool/bast fibre blended upholstery fabrics are currently being explored for recyclability and reuse by separating the fibre components and re-processing extracted bast fibres back to fabric production. In addition, the project has also demonstrated the potential to extract the dyes from waste fabrics and reuse for textile coloration. The outcomes from the projects could support the transition of the textile industry to a circular system.
dc.title: Enzyme-based textile coloration dc.contributor.author: Prajapati, Chetna; Netithammakorn, Nalinee; Smith, Edward; Shen, Jinsong dc.description.abstract: Textile coloration is typically characterised as a resource intensive production process that requires the use of large amounts of water, high concentrations of processing chemicals, high temperatures and long processing times, commonly resulting in high energy consumption and effluent waste. Consequently, this has led to rethinking approaches to textile coloration. The research presented gives an overview of current studies that investigated the use of two specific oxidoreductase enzymes, laccase (EC 1.10.3.2) and peroxidase (EC1.11.1.7) to develop a one-step coloration process. Both enzymes are capable of polymerising simple aromatic compounds to form colorants with the potential for textile coloration through the formation of conjugated chromophores via their distinctive catalytic oxidation and coupling/polymerization mechanism. A diverse gamut of hues were achieved on a range of different fibre types (flax, wool and nylon) through enzymatic catalysis of various aromatic compounds as laccase or peroxidase substrates or precursors and alteration of processing parameters such as buffer systems, pH values and reaction times. Enzymatically dyed fabrics were tested against commercial standards, resulting in reasonably good colour fastness to wash. The research demonstrates the potential offered by laccase and peroxidase as transformative tools to replace conventional industrial coloration and surface pattern design processes with biological systems, which offer important advantages of simpler processing using milder conditions that eliminate additional chemical use and reduce energy consumption. The adoption of enzyme-based biotechnologies could help the textile coloration industry transition towards a sustainable future.
dc.title: 3D Printing Based on Material Extrusion to Create Surface Patterns on Textile Fabrics dc.contributor.author: Alsabhi, Randa; Davies, Angela; Bingham, Guy; Shen, Jinsong dc.description.abstract: 3D printing technology has been developing rapidly in recent years. This technology is extensively used for producing prototypes of products and their designs with a wide range of materials in the manufacturing industry. The Fused Deposition Modelling (FDM) process uses the extrusion of molten thermoplastic materials through heated printing nozzle to create design objects layer by layer. The current research was to develop 3D printing technology on textile fabrics to create surface design based on FDM process using the Ultimake 3D printer. Printing parameters play an important role for printing on fabrics specially to achieve strong adhesion between the printed patterns and the surface of the fabrics. This research developed a method for assessing the attachment strength in the interface between the printed objects and the surface of fabrics. The effect of the initial setting distance between the printing nozzle and the printing platform on the performance of 3D printed fabrics was investigated. The research work demonstrated the ability to create different design patterns in 3D on the fabrics with excellent durability to washing, which shows potential for the commercial application in fashion industry. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: A study of new washing machine for the care of delicate garments by testing on wool and silk fabrics dc.contributor.author: Zhao, Xin; Shen, Jinsong; Ding, Xuemei dc.description.abstract: There is an increasing demand for gentle laundry and care of the delicate and high-end garments for maintaining their performance and appearance during the use. A tapping washing system was designed for the care of delicate garments. Adjustable and steady up-down tapping force was applied on fabrics or garments during laundry through the centric slider-crank mechanism with control parameters, such as the magnitude and frequency of the tapping force, washing temperature and duration, etc. By comparing with traditional drum rotation washing on wool and silk fabrics, the tapping washing method could prevent felting shrinkage of wool fabrics and crease of silk fabrics, and maintain their good appearance, although the washing efficiency for the removal of soils from garments needs to be further explored. The newly designed prototype of the tapping washing device could be the foundation for future research on gentle washing without the movement of fabrics but circulation of detergent washing solution during tapping action on the fabrics. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: New Approaches for Textile Colouration and Surface Pattern Using Enzyme-based Biotechnology dc.contributor.author: Prajapati, Chetna; Smith, Edward; Kane, Faith; Shen, Jinsong dc.description.abstract: The research presented in this paper gives an overview of a study which was undertaken to investigate the potential offered by the enzyme laccase (EC.1.10.3.2) as a creative design tool for innovative coloration and decorative surface pattern of textiles with a focus on providing sustainable alternatives to conventional processes used in industry. Research was conducted in two parts. The control (scientific) phase explored laccases potential for transforming a range of colourless aromatic compounds into coloured polymeric products via its reaction mechanism, and its ability to facilitate the coloration of most commonly used textile fibre types. Reaction processing parameters such as temperature, pH values, aromatic compound concentrations, and reaction times were investigated to achieve a diverse colour palette, ranging from light - medium to dark shades of blue, green, pink, purple and yellow hues. Wool and nylon fibre types were found to be most suitable for laccase-catalysed coloration. The creative phase investigated the design potential offered by the enzymatic coloration process developed; different and contrasting substantivity properties offered by various fibre types were exploited to produce shadow, reserve, and contrasting coloured effects on specially woven jacquard fabrics. The research demonstrates the potential offered by laccase as a transformative tool to replace conventional industrial coloration and surface pattern design processes with biological systems, which offer important advantages of simpler processing using milder conditions that eliminate additional chemical use and reduce energy consumption. The adoption of enzyme-based biotechnologies could help the textile industry transition towards a sustainable future. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: The Evaluation of Orthotics in Reducing Hallux Valgus Angle in Patients with Hallux Valgus over a Twelve-Month Treatment dc.contributor.author: Li, Guoli; Shen, Jinsong; Smith, Edward; Patel, Chetna dc.description.abstract: Background: Hallux valgus (HV) is one of the most common forefoot deformities among females, and its prevalence increases with age. This study aims to evaluate the effectiveness of three different types of orthotics on the reduction in hallux valgus angle (HVA) for patients with mild and moderate hallux valgus deformities. Methods: Twenty-six patients (42 feet) with mild or moderate HV participated in the treatment with three types of orthotics in the current study. Patients were divided into three groups depending on their HV severities and the consideration of different function of the orthotics. Orthotic Type 1 is a biomechanical style orthotic applied to moderated HV in Group 1. Orthotic Type 2 is a wrap style orthotic used on mild and moderate HV with two sub-groups: mild HV in Group 2A and moderate HV in Group 2B. Orthotic Type 3 is a gel style orthotic for mild HV. Patients were required to wear the orthotics for between 6 and 8 h per night over a period of 12 months. The HVA was measured every 3 weeks using a newly designed Measuring Block. A paired t-test was used to compare the differences between initial and final HVA at different stages of HVA treatment with orthotics. Results: After the 12-month treatment, for moderate HV patients treated with the Orthotic Type 1, their HVA reduced by 5.05 degree (95% CI 1.37, 8.73), (p < 0.05). For moderate HV patients treated with the Orthotic Type 2, their HVA reduced by 1.2 degree (95% CI -0.71, 3.11) (p > 0.05). For mild HV patients treated with the Orthotic Type 2, their HVA reduced by 2.44 degree (95% CI 1.39, 3.49) (p < 0.05). For mild HV patients treated with the Orthotic Type 3, their HVA reduced by 3.08 degree (95% CI -0.68, 6.83) (p > 0.05). Conclusions: Orthotic Type 1 showed a consistent significance in reduction in the HVA during the 12-month treatment, so it could be recommended for treating moderate HV. Orthotic Type 2 reduced the HVA, but it did not show a consistent significance in reduction in the HVA for mild and moderate HV. Orthotic Type 3 reduced the HVA, but it showed a volatile trend during 12 months without significant differences. dc.description: open access article
