- 2. Plain weave: • The plain weave is variously known as “calico” or “tabby” weave. It is the simplest of all weaves having a repeat size of 2. It consists of interlacing warp and weft yarns in a pattern of over one and under one.
- 3. • Plain weave is obtained by raising all even-numbered warp ends at one pick and raising all the odd numbered ones at the other pick. It means threads interlacing in alternate order.The range of application of this weave is wide. Plain weave is used for structures, which range from very heavy and coarse canvas and blankets made of thick yarns to the lightest and finest cambries and muslins made in extremely fine yarns.
- 4. Characteristics of plain weave: The plain weave has the following characteristics : It has the maximum number of binding points • The threads interlace on alternate order of 1 up and 1 down. • The thread density is limited • Cloth thickness and mass per unit area are limited. • It produces a relatively stronger fabric that is obtained by any other simple combination of threads, excepting that of “gauze”or “cross weaving”
- 6. Warp rib: • A warp rib results from extending the plain weave in the warp direction. Characteristics: • It produces a rib or cords effect in the weft direction • Generally warp yarn is finer than weft • Two or more weft yarns are passé over or under a warp • Weft yarn are low twisted yarn • Two heald shaft are used for producing design • It is mostly used for warp faced construction, such as poplin fabric.
- 7. TYPES OF WARP RIB WEAVE : • REGULAR WARP RIB WEAVE: • if number of ends are equal like numbers of picks than the weavve is termed as regular warp rib weave. • IRREGULAR WARP RIB WEAVE: • if number of ends are un equal like numbers of picks than the weavve is termed as regular warp rib weave.
- 8. Weft rib: • a weft rib structure results from ex tending the plain weave in the weft direction Characteristics of warp rib weave: • It produces a rib or cords effect in the warp direction • Generally weft yarn is finer than warp • Two or more warp yarns are pass over or under a weft • Two heald shaft are used for producing design • It is mostly used for producing blankets, hair cords etc.
- 9. TYPES OF WARP RIB WEAVE : • REGULAR WEFT RIB WEAVE: • if number of ends are equal like numbers of picks than the weavve is termed as regularwarp rib weave regular weft rib weave: • IRREGULAR WEFT RIB WEAVE: • if number of ends are un equal like numbers of picks than the weavve is termed as regularweft rib weave
- 10. Matt or Basket weave: • Basket weave is a variation of the basic Plain Weave construction. It used a Warp and a Weft yarn like in all types of weaving. • Like plain weave, Basket weave follows the same pattern of the Weft yarn going under one warp yarn and over the next, creating a checkerboard effect.
- 11. • The difference between basket weave and plain weave is that adjacent yarns are grouped together. They are usually grouped in pairs, but sometimes more yarns can be grouped together. These are woven as if they are one yarn.
- 12. Properties of Basket Woven Fabrics: • Interesting pattern created • Different coloured yarns can be used to create a contrast • More pliable and stronger than plain weave • Loose • Not as stable as plain weave • Frays easily • No Crosswise of lengthwise stretch • Flatter than plain weave • Less of a crimp • Drapes Well • Fibres and yarns used dictate the properties of the finished fabric
- 13. • End Uses of Basket Woven Fabrics • Outerwear • Monks Clothing • Draperies • Garments
