It offers someguidelines for the transaction of the course content and for undertakingthe practical work listed in the course content. As the curriculum is activitybased, process oriented and rooted in constructivism focusing on therealisation of learning outcomes, it demands higher level proficiency anddedication on the part of teachers for effective transaction.</p><p> In the context of the Right- based approach, quality education has to beensured for all learners. The learner community of Vocational HigherSecondary Education in Kerala should be empowered by providing themwith the best education that strengthens their competences to becomeinnovative entrepreneurs who contribute to the knowledge society. Thechange of course names, modular approach adopted for the organisationof course content, work-based pedagogy and the outcome focusedassessment approach paved the way for achieving the vision of VocationalHigher Secondary Education in Kerala. The revised curriculum helps toequip the learners with multiple skills matching technological advancementsand to produce skilled workforce for meeting the demands of the emergingindustries and service sectors with national and global orientation. Therevised curriculum attempts to enhance knowledge, skills and attitudes bygiving higher priority and space for the learners to make discussions insmall groups, and activities requiring hands-on experience.The SCERT appreciates the hard work and sincere co-operation of thecontributors of this book that includes subject experts, industrialists andthe teachers of Vocational Higher Secondary Schools. The developmentof the teachers version of reference books has been a joint venture ofthe State Council of Educational Research and Training (SCERT) and theDirectorate of Vocational Higher Secondary Education.The SCERT welcomes constructive criticism and creative suggestions forthe improvement of the book.</p><p>With regards,Dr. J. Prasad</p><p>DirectorSCERT, Kerala</p></li><li><p>Vocational Higher Secondary Education in Kerala is a unique scheme of education which combines both</p><p>vocational and academic stream of education. Learning vocational skills along with conventional academic</p><p>education gives the students double advantage of vertical mobility as well as employability. It helps to</p><p>develop vocational aptitude, work culture, values and attitudes of the learner and enhances his</p><p>productivity. The vision of Vocational Higher Secondary Education in Kerala is to equip the youth with</p><p>multiple skills matching the technological advancements and to produce skilled work force for meeting the</p><p>demands of the emerging industries and service sectors with national and global orientation.</p><p>As India is emerging as a manufacturing hub to the world the demand for skilled manpower is on</p><p>the rise. Kerala, traditionally known for its high quality man power all over the world can embark on this</p><p>opportunity and equip our students with skills for the manufacturing sector and reduce the unemployment</p><p>problems of the state. The Textile technology course in VHSE is one such course from the manufacturing</p><p>sector</p><p>Textile industry is the one of the oldest industries in India. The industry basically involves the</p><p>manufacturing of various types of fabrics both natural and synthetic, production of machinery, and</p><p>planning and development of new technology. The industry has categorized three areas of work namely</p><p>research and development, manufacturing and merchandizing. It provides direct employment to 30 million</p><p>peoples. Textile technology is the study of textile production , processing and its capability for the use of</p><p>common man. It combines the principles of engineering with specific knowledge of textile equipments and</p><p>textile process. Textile technology is deals with the application of scientific and engineering principles to</p><p>the design and control of all aspects of fibre, textile and apparel process, its products and machinery. These</p><p>include natural and man made material , interaction of materials with machines , safety and health, energy</p><p>conservation ,and waste and pollution control. There is wide scope for research in this area as the industry</p><p>demands the need to improve currently available products and develop new ones.</p><p>Textiles are utilized for innumerable purposes other than manufacturing of garments. They are</p><p>used in the manufacture of carpets and furnishings like bed sheets and bed covers , quilts, table cloth,</p><p>curtains ,towels etc. it is also used rags, dusters, tents and nets, kites, parachutes etc. According o the</p><p>usage and texture textiles are classified as Apparels ,Furnishings , Technical textiles , Medical textiles, Agro</p><p>textiles and Geo textiles.</p><p>This course is now offered in modular format consisting of four modules which focus on multi skills</p><p>development. One month On The Job Training and Production cum training centers are also an integral</p><p>part of the course which gives exposure to real time work environment.</p></li><li><p>On the successful completion of this course the candidate will be able to join Textile industries as</p><p>junior level technicians / operators and are also eligible for attending advanced courses on Textile</p><p>Technology or any other courses that can be pursued after plus two science stream A few institutes</p><p>offering higher learning courses in Textile Technology are listed below.</p><p>1. Three Government polytechnics colleges in Kerala offer Diploma in Textile Technology</p><p>2. IEI offers Diploma and B. Tech. level courses similar to AMIE schemes</p><p>3. Various universities out side Kerala offer B. Tech. in Textile Technology</p><p>4. ATDC provides various Diploma Courses in Garment manufacturing Merchandizing, Pattern making etc.in</p><p>all over India</p><p>5. NIFT offers various Degree and Diploma courses related to Textile designing and Fashion Technology</p><p>Thus finally you have a wonderful opportunity to learn in demand skills with higher learning opportunities.</p><p>Come let's explore the wonderful world of Textiles</p><p>1. Job roles</p><p>Textile is one of the essential need of the human being. Textiles are present around us in clothing</p><p>materials, house hold articles, automobile, aircraft, medical products, geo textiles, and various industrial</p><p>applications. It is impossible to live without textiles. Textile industry is the largest industry in India which</p><p>offer many employment opportunities and is growing at a rate of 20 - 30% CAGR. As the per capita</p><p>consumption of textile materials in India is far below the global average, the industry will continue to show</p><p>robust growth in the next 10 - 15 years. This will create millions of job opportunities in Textile industries at</p><p>all levels.</p><p>Textile Technology course explores different Textile materials, their properties, important</p><p>application and processing to make final products.</p><p>VHSE course in Textile Technology provides the candidates with hands-on and theoretical</p><p>knowledge that prepares them for technician level jobs in the textile and allied industries. This is a great</p><p>opportunity to learn in-demand job skills.</p><p>PUBLIC SETCOR</p></li><li><p> Lab assistant</p><p> Trades man in Polytechnic Colleges</p><p> Technical assistant in Textile mills</p><p> Technical assistant in textile research organization</p><p>PRIVATE SECTOR</p><p> Skilled Technician in Textile Industry</p><p> Junior technician</p><p> Lab technician</p><p> QC inspector</p><p> Textile processing technician</p><p> Weaving machine operator</p><p>SELF EMPLOYMENT</p><p> Handloom Weaving Unit</p><p> Power loom Unit</p><p> Textile Processing Unit</p><p> Wick manufacturing Unit.</p><p> Yarn sourcing</p><p> Fabric sourcing</p><p>2.
