1.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.
Fibre neps, trash particles and seed-coat fragments are visible foreign matters in cotton. These foreign matters affect yarn & fabric appearance and reduce the efficiency of machines. In order to analyze these contaminations, This analyzer consists of micro card that converts the raw cotton into thin uniform web without removing impurities, is also scanned by CCD Camera and processed by imaging system to classify undesirable particles in terms of their size and number. This information will provide vital feedback in upgrading cotton material, efficiency and quality in blow room and carding processes.
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.
Bleaching consists of cleaning, removing dirt, natural oils, brining out inherent luster of fibers, swelling of fibers fur softness and absorbency. But all the bleaching process is carried out batch wise and thus uniformity in fabric preparation become difficult to attain. The present trend is to have long length fabric well prepared during earlier stages of processing so that final dyes or printed fabric or even full white material is of high quality. The continuous bleaching range is thus becomes highly useful in meeting these demands.
The development under this project integrates all stages of bleaching viz. desizing, washing and chemical application for bleaching and neutralization. Hence the process would over by 2 hrs against 36 hrs of batch process. Automatic chemical dosing system reduced the dwell time as well as the dependence on supervising. One full range has been manufactured and is under observation for performance evaluation.
2Over the past few years, the textile industry, once considered as handicrafts, has undergone various facelift. Along with the usage of original machines and processes, it has evolved into a more technologically-advanced version today. Machines utilized by skilled laborers to operate manually are now computerized and programmed to produce textile materials.
Textile technology involves highly sophisticated, scientific, and engineering processes encompassing various fields, such as instrumentation, electrical, computer, mechanical, chemical, electronic, and structural engineering. This article discusses the significant impacts of this latest technology on textile operations.
