Overview of the Global Textile Industry
The global textile industry impacts nearly every human being on the planet. The industry is currently worth nearly US $3 trillion and includes the production, refinement, and sale of both synthetic and natural fibers used in thousands of industries. The global textile market is broken into a number of sectors shown in the chart below. As you can see, the textile industry encompasses a broad and diverse range of products with an even wider range of applications. That diversity is one of many factors that makes the textile industry one of the most vital to the economic well-being of people all over the world.Textiles are an important source of reference for the cultural studies because of their universality. Textiles have always draped the body, whether human/deities/animal, floor and furniture. Unlike stone, clay, metal etc. textiles were traditionally made from biodegradable materials. Cotton (natural cellulose fiber), silk, wool (natural protein fibers) were three main materials for textiles, apart from bast and leaf fibers. Initially very simple technologies were used for making the textiles. The most basic skill involved spinning the fiber into yarn and then changes it to fabric by a process called weaving. The implements used for weaving and spinning were and in many parts of India still continue to be of biodegradable materials like wood .There is exist a very scant reference of the fabric making skills in the archaeological excavations. Along with the tools of their manufacture, fabric materials have long degraded in our tropical climate. Textiles consist of fibers, yarns, fabrics and finishes. Each of these stages has a variety of processes involved to reach the next stage. Hand and feet have even today remained the tools for various processes supported by materials like wood, terracotta, metal, yarns, beads, semiprecious stones, colors etc. The concept of the Indian textile technologies is intricately related to both, the manufacture and decoration. This may therefore be researched in a chronological framework starting from archaeological past to the contemporary times. Regional developments have been very typical to certain styles of manufacture and decorations in textiles.The technology for developing it from IIT Delhi to develop a digital image processing based pilling tester for objective evaluation of pilling instead of subjective and visual comparison. After the successful development it is expected that international standards like BS, ASTM, DIN and IS will incorporate the development as new standard for evaluation of pilling. The main function of Pilling Tester is to test the pilling (hair ball) characteristic of fabric and knit fabric cloths. Simulating the condition of when weaving materials are worn, it will have the appearance of lint. Rolling the specimen around a rubber tube and turning in a winding box for a period of time, it is then compared to a standard picture to determine its grade. Test results are usually determined after comparing with standard pictures, the average of four tests per specimen. But this development involves conversion of pilled fabric sample to digital image and stored in a memory by the image acquisition element. This image will be processed to obtain the various parameters like no. of pills, total pilled area, mean pill area and no. of pills per unit area. Download 96.47 Kb. Do'stlaringiz bilan baham: |
