Clothes are the basic necessity of man. The clothing industry will never see a halt or an end. Because people need to wear clothes all the time, it will never happen that one does not require clothes to wear, unless he is a robot. So situations like pandemic or inflation will not affect this industry on a large scale. If you have a good sense of design and know-how to play with color, you can think of doing a career in the textile industry. NPTEL is a great platform where you can learn more about the Textile industry, skills required for pursuing a career in this industry. NPTEL Textile courses give guide you through it. It provides e-learning through the web by using pre-recorded videos. Textile is a material that is flexible and is made a network of natural or artificial fiber. Using these items like clothes, rugs, tablecloths, chair upholstery can be made.

TEXTILE TESTING NPTEL
Textile testing is a process that involves a series of tests that examine its physical, mechanical, and chemical properties. This is an important stage and has to be done correctly so that the quality and material of the material is maintained and can be used as your requirements. It assesses the product performance and makes predictions of how will the textile turn. Distributors and consumers having good knowledge about textiles can determine the products end quality.
When you go to the NPTEL website you will find many courses, search for textile testing in the search box and you will find a variety of courses. You can see the detailed information and their syllabus in the description.
Textile testing NPTEL has course on –
- Technical Textiles
- Textile Finishing
- Science of Clothing comfort
- Textile chemical processing: Theory and practice of Preparatory Processes
- Mechanics of Textile Machinery
NPTEL TEXTILE SPINNING
Textile spinning is a twisting method in which the fiber is drawn out, twisted, and then wound into a bundle which is called yarn. Some fibers are synthetic, they can be converted into yarn by using different methods of spinning. There are various types of spinning techniques, the one which is most common and used worldwide is ring spinning. Others include air-jet and open-end spinning, break spinning, hand spinning with a spindle, mule spinning, etc. Traditional methods have been mixed with modern techniques to ease the work and have maximum efficiency.
NPTEL Textile spinning is included in the courses given below-
- Principles of combing, roving preparation and ring spinning
- Science and technology of weft and warp knitting
- Stuttleless weaving
- Yarn manufactures 1
- Yarn manufactures 2
- Theory of Yarn Structures
- Textured Yarn Technology
- Evaluation of textile materials
NPTEL TEXTILE DYEING
Dyeing is necessary to get color on that fiber as desired. Textile dyeing is a process in which there is an interaction between a dye and a fiber so that the dye gets into internal parts of the fiber either by absorption or diffusion. Dying is followed by printing.
Textile dyes include methods such as solution dyeing, stock dyeing, hank/skein dyeing, package dyeing, beam dyeing (yarns), winch/bleach dyeing, jet dyeing, jig dyeing, direct dying, yarn dying, etc. There are various types of dye natural dye, reactive dye, substantive dye, acid dye, dispersive dye, indigo dye, vat dye, pigment, etc.
NPTEL textile dyeing has course on –
Natural Dyes – It comes in textile engineering conducted by IIT Kanpur by Dr. Padma S Vankar.
Dyes are easily available at the markets and affordable rates. You can make dyes and home too by mixing the necessary ingredients by using DIY methods.
NPTEL TEXTILE FIBRE
Textile fibres are those fibres which have properties that allow them to be spun into the yarn or fabric. It can be natural or synthetic. Fibres play a significant role in the making of the clothing item. It should be comfortable, look good, durable, and true to the value. Hence selecting the right fibre is very important.
NPTEL textile fibres include courses such as quality control in the textile industry, these courses are conducted by IIT Delhi.
It will have an introduction to quality control, statistical interferences on quality of textile fibre, Shewhart control charts, non-Shewhart control process, process capability analysis, acceptance sampling techniques, six sigma, and its application to textiles. To have a hands-on knowledge of the fibres you need to touch the fibre and understand its textures and properties.
Online learning can build a good base for the theory, but you have to explore more to have practical experience.
NPTEL TEXTILE WEAVING
A textile can be produced by weaving. Two distinct sets of threads or yarns are intersected at 90 degrees and in series to form a cloth or a fibre. It can be done with hands or on the weaving machines. Tools that are required for this process are frame loom, tapestry yarn, warp yarn, shed stick, weaving comb, scissors, dowels, etc. There are three types of weaving types – plain, twill and satin. Theses are given names based on how are they interlaced. The closeness or looseness of a weave is known by the number of warp and fillings yarn to the square inch.
