INTRODUCTION Fabric are manufactured in wide varieties and design. And the different design and effect is produced on the fabric with the help for various mechanism which is helpful to from different weaves and lots of design which enhances the look of apparels. The present paper was aimed at investigating the different types of weaves and also overview the fabrics come under the different weave categories. The way in which the warp threads are laced or woven together determines the structure of the cloth. There are three basic weave structures from which most woven patterns originate. The three basic weave structures are Plain Weave, Twill Weave and Satin Weave.


PLAIN WEAVE Most simple and most common type of construction Inexpensive to produce, durable, Flat, tight surface is conducive to printing and other finishes. The simplest of all patterns is the plain weave. Each weft yarn goes alternately over and under one warp yarn. Each warp yarn goes alternately over and under each weft yarn. Some examples of plain weave fabrics are crepe, taffeta, organdy and muslin. The plain weave may also have variations including the following:   Rib weave: the filling yarns are larger in diameter than the warp yarns. A rib weave produces fabrics in which fewer yarns per square centimeter are visible on the surface.   Matt Weave or Basket weave: here, two or more yarns are used in both the warp and filling direction. These groups of yarns are woven as one, producing a basket effect.


BASKET WEAVE A variation of the plain weave usually basket or checkerboard pattern Contrasting colors are often used Inexpensive, less durable than plain weave. Basket weave is the amplification in height and width of plain weave. Two or more yarns have to be lifted or lowered over or under two or more picks for each plain weave point. When the groups of yarns are equal, the basket weave is termed regular, otherwise it is termed irregular.   There two types of weave come under this category i.e. regular and irregular weave.  a)    Regular basket weave: This is commonly used for edges in drapery, or as a bottom in very small weave repeats, because the texture is too loose-fitting for big weave repeats; moreover, yarns of different groups can slip, group and overlap, spoiling the appearance. This is why only basket weaves 2-2, 3-3 and 4-4 exist.   b)    Irregular basket weave: This is generally a combination of irregular warp and weft ribs.


TWILL WEAVE Creates a diagonal, chevron, hounds tooth, corkscrew, or other design. The design is enhanced with colored yarn is strong and may develop a shine. Twill weave is characterized by diagonal ridges formed by the yarns, which are exposed on the surface. These may vary in angle from a low slope to a very steep slope. Twill weaves are more closely woven, heavier and stronger than weaves of comparable fiber and yarn size. They can be produced in fancy designs.


SATIN WEAVE Used for ribbons, trimmings, dresses, linings etc, and originally was an all silk fabric with a fine rich glossy surface formed in a warp satin weave. The warp is much finer and more closely set than the weft, and the latter which only shows on the under side is frequently composed of cotton. Double faced Satins are made on the reversible warp backed principle, with one side differently colour from the other. Sateen; A cotton fabric is made in 5 thread weft face sateen, and woven like cotton. It is sold in bleached, mercerized or printed condition.


FANCY WEAVES Jacquard:- refers to large figured designs that require more than 25 different arrangemetn of the warp yarns to complete one repeat design. Leno:- refers to any leno weave fabric in which two warp yarns are crossed over each otherand held in place by a filling yarn. this requires a doup attachment on the loom Pile:- a 3d structues made by weaving an extra set of warp or filling yarns into the ground yarns to make loops or cut ends on the surface


FANCY WEAVES Pique:- is a fabric made on dobby or jacquard loom with carded or combed yarns; some piques are made in variety of pattern; filling cord; three or more sets of yarns. Momie:- is a weave that present no wale or other distinct weave effect but gives the cloth the appearance of being sprinkled with small spots or seeds. Dobby:- is a small figure woven in design in which fewer than 25 different warp yarn arrangements are required to create one desing repeat.


FANCY WEAVES Tapestry:- is a frim heavy stiff jacquard weave fabric made with serveral warp and filling yarns are discontinous. In these tapestries the filling yarn is used only in the areas where that color is desired. Double Cloth:- is a fabric made by weaving two fabrics with four sets of yarns on the same loom. The two fabrics are connected by periodically reversing teh positions of the two fabrics from top to bottom. Double weave is also known as pocket cloth or weave. Slack Tension:- is a weave in which two warp beams are used withone beam at regular loom tension and the other beam at a lower tension for weaving seersucker and terrycloth
