Textile industry plant processes

  1. 1. TEXTILE INDUSTRY OF PAKISTAN
  2. 2. • Textile is a term that comes from “texere” which is a Latin word, that means “to weave”. • A cloth, especially one manufactured by weaving or knitting; a fabric. About Textile
  3. 3. • The textile industry is often considered the backbone of the Islamic Republic of Pakistan’s economy. • Pakistan’s textile Industry is the fourth Largest Cotton Producer. • 6th largest importer of raw cotton • The Third largest Consumer Introduction
  4. 4. Value chain of textile industry RAW MATERIAL TEXTILE PLANTS SPINING WEAVING DYING PRINTING BLEACHING APPAREL PLANTS DISTRIB. CENTRES RETAIL STORES CUSTOMERS
  5. 5. Process Flow Chart of Textile Manufacturing  Spinning ↓ Weaving ↓ Bleaching+Dyeing +Printing ↓ Garments Manufacturing 
  6. 6. SPINNING• Spinning is the process of converting fibers into yarn. • The fibers maybe natural fibers such as cotton or man made fibers such as polyester. • What so ever is the case the final product of spinning is yarn.
  7. 7. SPINNING CONSIST OF • Blowing and mixing • Carding • Combing • Roving • Spining • Winding
  8. 8. Blow room carding
  9. 9. ROVING MACHINE COMBER MACHINE
  10. 10. RING SPINNING MACHINE WINDING MACHINE
  11. 11. WEAVING • weaving sector is one of the most important textile sub sector. • Weaving is a process which turns yarns into cloth. • The machine used for weaving is the loom
  12. 12. Weaving comprises on : •WARPING:Warping is the first step of fabric manufacturing process. ... In textile language;warping is defined as the parallel winding of yarn from cone or cheese package on to a warp beam. •SIZING:Sizing is the process of applying an adhesive coating on the surface of the yarn. Sizingis applied into the yarn mainly to improve the weave ability of warp yarn by making it more resistant to action of weaving i.e. absorption, friction, tension & flexing.
  13. 13.  WEAVING:Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. The longitudinal threads are called the warp and the lateral threads are the weft or filling.
  14. 14. WARPING MACHINE WEAVING MACHINE
  15. 15. BLEACHING  Bleaching means the removal of the all color impurities. Woven and knitwear fabric that made of wool, cotton and silk are not white owing to their natural color or contamination in the preceding process, for fabric that have to dyed in pure white or any color, the has to bleached. Bleaching is done by different methods such as • Hydrogen peroxide(H2O2) • Sodium hypochlorite (NaClO) • Sodium Chlorite(NaClO2)
  16. 16. DYEING  Dyeing in textiles is a process in which color is transferred to a finished textile or textile material (like fibers and yarns) to add permanent and long- lasting color. It can be done by hand or by machine. ... When the textile and the dye come into contact, the textileis completely saturated by the dye and colored.
  17. 17. Some specific dyeing materials are mentioned for some fiber materials  Different dyeing materials are used for different fiber materials. Various dyeing materials exits, as the fiber posses different reactive groups due to their chemical structure  Cellulose: • Direct Dyes • Vat Dyes • Reactive Dyes • sulfur dyes  Wool: • Acid Dyes • Chrome developed dyes  Polyester: • Disperse dyes
  18. 18. Printing Printing is actually a type of dyeing. The main difference between printing and dyeing is that in dyeing the fabric is given one color only by dipping in the solution of dye, whereas in printing different colors are applied according to the requirement of design.
  19. 19. WEAVING MACHINE
  20. 20. PRINTING MACHINE  For printing usually four types of machines are used.  • ROLLER PRINTING MACHINE  • MULTI ROLLER PRINTING MACHINE  • FLAT BELT PRINTING MACHINE  • ROTARY PRINTING MACHINE
  21. 21. FINISHING DEPARTMENT In textile manufacturing, finishing refers to the processes that convert the woven cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textileor clothing.
