3. Weaving is the intersection of two sets of straight yarns, warp and weft, which cross and interlace at right angles to each other. The lengthwise yarns are known as warp yarns and widthwise yarns are known as weft or filling yarns and the fabric produced is known as woven fabric. Example: Plain, Twill, Shatin Application: Gavadin, Denim,, Poplin etc Woven Fabric: www.AssignmentPoint.com

4. Knitting is a process of manufacturing a fabric by the intermeshing of loops of yarns and the fabric produced this is known as knitted fabric. Example: Single Jersey, Double Jersey Application: T-Shirt, Polo- Shirt, Stocking etc. Knitted fabric: www.AssignmentPoint.com

5. Non wovens are a sheet, web or bat of natural and manmade fibres or filaments, excluding paper, that have been covered into yarns and that are bonded to each other by any of several means – web formation, web bonding. Example: Fusible (interlining), Coated fabrics, Film fabrics. Application: Diapers, sanitary napkin, industrial musk, bandages etc. Non woven: www.AssignmentPoint.com

6. Braid is one kind of narrow fabric. This kind of fabric is formed on braiding m/c by interlacing three or more strands of yarn. The process of interlacing three or more threads in such a way that they cross one another is laid together in diagonal formation. Example: Fire brigade water pipe, shoe lace, cloth lines, electric wire, ropes etc. Braid: www.AssignmentPoint.com

7. The unit of woven fabric is the point of intersection of a warp end and a weft pick. The interlacing is of two possible kinds- A. Warp over weft interlacing. B. Warp under weft interlacing. In this interlacing, the warp thread is raised to produce interlacing. In this interlacing, the warp yarn is lowered to produce interlacing. Methods of Fabric Representation: www.AssignmentPoint.com

9. The vertical lines/ space is to represented a warp end • The Horizontal space is to represent to a weft pick. • Each square indicates an intersection of an end and a pick. •  Represents warp up over weft. And  represents weft up over warp. • There are two and only two possibilities of each crossing, either the end passes over the pick or the pick passes over the end. • Only one repeat should be shown on design paper. • Symbols indicate repeat unit. • # Represents starting point.

10. Some Important Terms or Factors Formula Number: Formula number is notation diagram which represent the warp and weft interlacing point. The system of expressing the fabric representation is called Formula number.The warp floats coming up are put above the fraction line and the weft floats going down are put above the fraction line and the weft floats going down are put under the fraction line. www.AssignmentPoint.com

11. Formula no of warp = Formula no of weft = www.AssignmentPoint.com

12. PlainEach warp fiber passes alternately under and over each weft fiber. www.AssignmentPoint.com

13. TwillOne or more warp fibers alternately weave over and under two or more weft fibers in a regular repeated manner. www.AssignmentPoint.com

14. Satin Satin weaves are fundamentally twill weaves modified to produce fewer intersections of warp and weft. www.AssignmentPoint.com

15. Basket Basket weave is fundamentally the same as plain weave except that two or more warp fibers alternately interlace with two or more weft fibers. An arrangement of two warps crossing two wefts is designated 2x2 basket, but the arrangement of fiber need not be symmetrical. Therefore it is possible to have 8x2, 5x4, etc. www.AssignmentPoint.com

16. Leno A form of plain weave in which adjacent warp fibers are twisted around consecutive weft fibers to form a spiral pair, effectively ‘locking’ each weft in place. www.AssignmentPoint.com

17. Mock Leno A version of plain weave in which occasional warp fibers, at regular intervals but usually several fibers apart, deviate from the alternate under-over interlacing and instead interlace every two or more fibers. www.AssignmentPoint.com
