Development of a Sustainable Coated Textile (Fabric) or Biocomposite Using a Combination of Fibrous Materials (Plant-based fibres and Agricultural and

使用纤维材料（植物纤维、农业和家禽废弃纤维）和聚合物开发可持续涂层纺织品（织物）或生物复合材料，用于工业和医疗应用合成聚合物或塑料具有许多独特的优势，如可用性、高强度和重量轻，这导致塑料应用在生活的各个方面。但塑料也有主要的缺点，如不可生物降解，缺乏可持续和生态友好的合成和加工系统，泄漏问题等，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中应用。为了解决这个问题，人们尝试了天然生物聚合物，但不同的聚合物有不同的问题，如加工性能差、价格高等。这些问题导致在各种应用中使用纤维增强复合结构（由不同的聚合物和纤维材料制成）。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。第二个目的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。有关详情如下。原材料：采用天然纤维为主要原材料制作无纺布结构。对于树脂，将从几个选项中选择最合适的一个来制备树脂。如果需要，天然粘合剂可以结合纤维并在纤维和树脂之间形成结合。可能需要额外的化学品来赋予一些其他所需的性质（软化/改善疏水性/改善机械性质/改善柔韧性等）。到布料上。机器：将需要非织造织物装置（实验室规模）来从纤维生产非织造片材。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，也可以使用手工涂抹粘合剂和涂层材料。研究将从纤维收集开始。这些纤维必须经过常规的处理（清洗、精练等）。然后将其转化为所需的织物片，并在之后施加涂层。如果需要，在施加涂层之前将粘合剂施加到织物表面。但在这种情况下，粘合剂的粘度将需要保持在较低区域，以确保渗透到纤维内和纤维中。通常，涂层将具有比粘合剂更大的粘度。将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），以获得涂层的最佳效果。织物在涂上涂层后，将经过适当的固化过程，然后进行不同的特性测试。拟议的研究领域包括工程和物理科学领域，这是EPSRC的职权范围。具体而言，拟议的研究涉及纺织品和生物材料化学，使用先进技术和仪器对材料进行调查。

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.
