Development of a Sustainable Coated Textile (Fabric) or Biocomposite Using a Combination of Fibrous Materials (Plant-based fibres and Agricultural and Poultry waste fibres) and Polymers for Industrial and Medical Applications.Synthetic polymers or plastics offer a number of unique advantages such as availability, high strength, and lightweight, which have led to the expansion of plastic applications in every aspect of life. But plastics also have major disadvantages such as non-biodegradability, lack of sustainable and eco-friendly synthesis and processing systems, leakage problems, etc., which make most cheap synthetic polymers unsuitable for applications in the industrial and medical sectors. To solve the problem, natural biopolymers have been tried, but different polymers have different problems like poor processability, high price, etc. These problems lead to the use of fibre-reinforced composite structures (made of different polymers and fibrous materials) in various applications. Therefore, the proposed research aims to investigate the development of coated textiles or composite structures that could replace synthetic products in the industrial (packaging) and medical (surgical and hygiene) sectors. The secondary aim is to ensure the sustainability of the product in terms of the production process and the product itself.The work will involve different raw materials, while some special machines would be required for developing the required structure. Details on them are given below. Raw Materials: Natural fibre would be taken as the main raw material for the nonwoven structure. For the resin, the most suitable one from several options will be taken to prepare the resin. A natural adhesive may bind the fibres and form bonds between the fibres and resin if required. Additional chemicals may be required to impart some other required properties (softening/improving hydrophobicity/improving mechanical properties/improving flexibility, etc.,) to the fabric. Machines:A nonwoven fabric setup (laboratory scale) will be required to produce the nonwoven sheet from the fibres. Standard equipment used in a chemistry laboratory would be sufficient for the chemical modification of the resin. In the last segment of the development part, a fabric coating machine (laboratory scale) will be used. However, manual application of adhesive and coating material too could be used.The research will be started with fibres collection. The fibers will have to go through routine processes (cleaning, scouring, etc.) before being converted into the required fabric sheet and the coating would be applied afterward. The adhesive would be applied to the fabric surface if required before applying the coating. But in that case, the viscosity of the adhesive would be required to be kept in the lower region to ensure penetration within and into the fibres. Normally, the coating would have more viscosity than the adhesive. Chemical modifications would be done to the coating polymer, or a combination of different polymers would be specified (depending on the requirements of the end products) to get the best result from the coating. After the application of the coating, the fabrics will go through proper curing processes before being taken to different characterisation tests.The proposed area of research covers the area of engineering and physical sciences, which is the remit of the EPSRC. Specifically, the proposed research involves textile and biomaterial-based chemistry, investigation of materials using advanced techniques and instrumentation.

使用纤维材料（植物基纤维以及农业和家禽废弃纤维）与工业和医疗应用聚合物的组合开发可持续涂层纺织品（织物）或生物复合材料。合成聚合物或塑料具有许多独特的优势，例如可用性、高强度、轻量化，使得塑料应用范围扩大到生活的各个方面。但塑料也存在不可生物降解性、缺乏可持续且环保的合成和加工系统、泄漏问题等重大缺点，这使得大多数廉价的合成聚合物不适合在工业和医疗领域应用。为了解决这个问题，人们尝试了天然生物聚合物，但不同的聚合物存在不同的问题，如加工性差、价格昂贵等。这些问题导致纤维增强复合结构（由不同聚合物和纤维材料制成）在各种应用中的使用。因此，拟议的研究旨在研究涂层纺织品或复合结构的开发，以取代工业（包装）和医疗（外科和卫生）领域的合成产品。第二个目标是确保产品在生产过程和产品本身方面的可持续性。这项工作将涉及不同的原材料，同时需要一些特殊的机器来开发所需的结构。下面给出了它们的详细信息。原材料：无纺结构以天然纤维为主要原材料。对于树脂，将从多种选择中选择最合适的一种来制备树脂。如果需要，天然粘合剂可以粘合纤维并在纤维和树脂之间形成粘合。可能需要额外的化学品来赋予织物一些其他所需的性能（软化/改善疏水性/改善机械性能/改善柔韧性等）。机器：需要无纺布装置（实验室规模）来用纤维生产无纺布片材。化学实验室中使用的标准设备足以对树脂进行化学改性。在开发部分的最后一部分，将使用织物涂层机（实验室规模）。然而，也可以使用粘合剂和涂层材料的手动施加。研究将从纤维收集开始。纤维在转化为所需的织物片材之前必须经过常规工艺（清洁、煮练等），然后再进行涂层处理。如果需要，在施加涂层之前，可以将粘合剂施加到织物表面。但在这种情况下，粘合剂的粘度需要保持在较低区域，以确保渗透到纤维内部和内​​部。通常，涂层的粘度高于粘合剂。对涂层聚合物进行化学改性，或者指定不同聚合物的组合（取决于最终产品的要求），以获得最佳的涂层效果。涂覆涂层后，织物将经过适当的固化过程，然后进行不同的表征测试。拟议的研究领域涵盖工程和物理科学领域，这是 EPSRC 的职权范围。具体来说，拟议的研究涉及基于纺织品和生物材料的化学、使用先进技术和仪器对材料进行研究。
