  4. 4. In the form of spinner’s package Warp preparation Weft preparation Winding (cone, Cheese) Winding (Cop,pirn) Warping(pre beam,warp) Weaving Sizing (weavers beam) Drafting, Drawing,Denting, Weaving
  5. 5. Cone Winding • Winding is a process of transferring yarns from ring bobbins, hanks, cones etc into a convenient form of packages containing considerably long length of yarn. • The main purpose of winding or packaging is to form a single yarn package suitable for the next operation.
  6. 6. Creeling
  7. 7. Warping Warping is aimed at preparing the weaver’s beam to be set up on the weaving machine. Warping carries out following operations : • Creation, out of a limited number of warp threads (creel load), of a warp composed of any number of threads with the desired length. • Arrangement of above-mentioned threads according to the desired sequence. The industrial warping process can be carried out according to two different technologies: • Sectional warping (conical drum or indirect warping). • Beam warping or direct warping (preparatory beam warping).
  8. 8. • Sizing is the application of adhesive coating in the warp threads before weaving. • The warp yarns can withstand the complex stresses to which they are subjected in the weaving machine.
  9. 9. • The size is usually a starch paste containing softening and other ingredients. • Starch sizes are usually not satisfactory for synthetic fiber threads and have to be replaced by special sizes (often containing synthetic polymers) which will adhere better to the threads.
  10. 10. • To pass the warp threads through the hole of the drop wire is known as pinning. • If a single warp breaks drop wire will drop. As a result Machine will stop instantly to avoid end missing. Before the weaver’s beam is mounted on the loom, each end is threaded through a heald eye and the reed; it also supports a drop wire.
  11. 11. • To pull the warp threads through the heald eye of the heald wire. • The process of drawing in is also known as entering and knotting or looming. • It is the process that connects the sizing and weaving. • The important operations of this process are leasing, drawing, tying and dropper-pinning, which in turn depend on different types of yarn,Colour planting, weaving machine type, and character of pr oduction, i.e., degree of diversity.
  12. 12. • Drafting is known as the selection of heald frames or harnesses for individual warp threads according to the design. • Drawing in: To pull the warp threads through the heald eye of the heald wire.
  13. 13. Reed • The reed is a comb-like structure consisting of regularly spaced wires. The word dent is commonly used to describe the space between two reed wires. Denting: • Denting means drawing the warp thread through the dent as required by reed plan and this determines more accurately the width of the fabric and the ends per cm.
  14. 14. • Tying-in is used when a fabric is being mass produced. • The tail end of the warp from the exhausted weaver’s beam is tied to the beginning of the new warp. • Therefore, if every end on the new beam is tied to its corresponding end on the old beam, the drawing-in process can be omitted. • Following the tying-in process, all knots are pulled through the drop wires, heddles and the reed. The loom is now ready for operation.
  15. 15. Weaving is the action of producing fabric by the interlacing of warp and weft thread. The warp threads are placed along the length of the fabric and the weft threads are placed along the width of the fabric. MOTIONS OF LOOM 1. Primary Motions a) Shedding Motion b) Picking Motion c) Beating-up 2. Secondary Motions a) Take-up motion b) Let-off motion 3. Auxiliary Motions a) Warp Stop Motion b) Weft Stop Motion c) Warp Protector Motion d) Weft Mixing Motion e) Feeler Motion f) Brake Motion
  16. 16. PRECAUTIONARY MEASURES Back of Loom (Warp Alley) • Slubs • Extra End • Missing End • Crossed End • Thick End Or Wrong Yarn Count • Stuck Ends / Sizing Fault • Spare End Bobbin • Fluff And Fly • Waste / Wild Yarn Front Of Loom (Cloth Quality) • Short Picks • Weft Bars • Uneven Yarn: • Broken Pick • Double End • Wrong Draft • Wrong Dent • Selvedge • Reed Marks
  17. 17. • I have enough fortunate to get an opportunity in Hema Chandran textile weaving mill during the period of 10 days. • I have received full cooperation and encouragement during the learning process by all the staff. • I have learnt the mechanism of power loom, preparatory process in fabric manufacturing. It`s an good exposure to see auto looms and advanced manufacturing in more for woven fabrics.
