Plain weave is the most common and tightest of basic weave structures in which the filling threads pass over and under successive warp threads and repeat the same pattern with alternate threads in the following row, producing a chequered surface. They do not ravel easily but tend to wrinkle and have less absorbency than other weaves. The plain weave is variously known as ?calico? or ?tabby? weave. It is the simplest of all weaves having a repeat size of 2.
Cellulosic chemical fibres of all lengths and degrees of refinement and with clearly different properties, are at the disposal of the industry of nonwoven bonded fabrics. They are all characterised by the ability to absorb a fairly high amount of moisture. That recommends their use wherever this property is useful for the production of nonwoven bonded fabrics and/or the use of nonwoven bonded fabrics is even a precondition.
In the simplest weaving arrangement, alternate warp yarns are over or under the shuttle as it
moves in one direction and the warp yarn positions are reversed for the return stroke of the
shuttle. This weave can be made on a loom with only two harnesses. In other arrangements, several warp yarns may be moved upward or downward together, or several filling picks may take place before the warp yarns change position.
Warp knitting is the sequential formation and interlinking of loops in an axial direction on a lateral array of needles with at least one separate thread being supplied to each needle. The loops are joined together in a width-wise direction by moving the threads back and forth between adjacent needles.
Major kind of textile fabrics used for clothing, home furnishing and industrial usages - the page briefly describes almost all commonly used fabrics and its characteristics and usages.
Twill is a type of textile weave with a pattern of diagonal parallel ribs. It can be identified by looking at the presence of pronounced diagonal lines that run along the width of the fabric. It has higher resistance to tearing than a plain weave because it has fewer yarn interlacing per area, therefore a greater degree of internal mobility. In addition, two yarns will bear the load when the fabric is torn.
The process of producing a fabric by interlacing warp and weft threads is known as weaving. The machine used for weaving is known as weaving machine or loom. Weaving is an art that has been practiced for thousands of years. The earliest application of weaving dates back to the Egyptian civilization. In order to interlace wrap and weft threads to produce a fabric, the basic mechanisms necessary on any type of looms are Primary, Secondary and Auxiliary mechanisms.
With the exception of the very simplest structures, it is too time consuming to represent warp knitted fabric using stitch or loop diagrams. For this reason two methods of fabric representation are commonly used a. Lapping diagrams, b. Numerical representation.
