Broken twill is formed by breaking the twill line of basic twill. Normally straight draft is used to produce this weave. Rearranged twill is produced by the rearrangement or transposition of the original order of the threads in the regular basic twill.
Relation Between Yarn Count and Diameter & count calculation for ply yarn
Normally, when two single yarns are twisted together one should expect some contraction or some increase in length depending on the twisting direction. A contraction will result in a yarn slightly coarser than the estimated value. In order to correct for this difference, typically 5% to 10% contraction or extension should be accounted for.
Derivatives of Plain Weave
There are two types of derivatives : Rib and Matt. In rib weave, it produces rib or cord effect in warp/weft direction. Used as grosgrain cloth, mattress cloth,hair cords, blankets etc. Matt is constructed by extending the plain weave both vertically and horizontally. Matt weave finds extensive uses for a great variety of fabrics such as dress materials, shirtings, sail cloth, duck cloth etc.
Melt Spinning , Dry spinning and Wet Spinning Method
Man-made fibers are manufactured by spinning the polymer. There are three major types of spinning process. They are-
█ Melt Spinning (It is used for polymers that can be melted easily.)
█ Dry Spinning (It involves dissolving the polymer into a solution that can be evaporated.)
█ Wet Spinning (It is used when the solvent can’t be evaporated and must be removed by chemical means.)
Computer Networks
Computer networks are collection of computer hardware & software that are interconnected and therefore help users to work togather .It connects computers , printers , scanners & cameras. Using computer network , user can send electronic massages to each other.
Speed Frame and function of speed frame
The output from the draw frame is fed into the roving frame (also called ‘speed frame or simplex machine or flyer frame‘) where the linear density of sliver is reduced by drafting and the resultant product is called the roving. After the drafting operation, the roving is wound on the bobbin. During winding, a little amount of twist is imparted to the roving.
History of Fashion
Fashion is the term used to describe a style of clothing or any other products worn or used by most people of a country. A fashion remains popular for a few months or years before being replaced by yet another fashion.
Twill & Angle of Twill Weave
A twill weave is characteristics by diagonal ribs (twill lines) on the face of the fabric. These twill lines are produce by letting all warp ends interlace in the same way but displaing the interlaceing points of each end by one pick relative to that of the previous end while the plain weave can only be woven in one form, there exit several options with regrad to twills.
Motion of Loom
Shedding is the operation by which the warp is divided into two sheets so that sufficient gap is created for the uninterrupted passage of the weft from one side of the loom to the other.
What Is Loom | Classification Of Loom
The weaving m/c is technically termed as loom .The loom is a device or m/c in which interlacement of warp and weft yarn performed and thus fabric is produced. In 1930's, eventually, each weaving machine driven individually by an electric motor was developed, this loom drive concept has remained in use until the present.
