Man Made Fibre and Man Made Fibre Production - Manufactured (MF) fibers (formerly termed “man-made”) are formed from a suitable raw material as a thick, sticky liquid, which is “spun” or extruded through spinneret holes, forming streams that are solidified into fibers.

The order of interlacement of warp and weft threads at right angles is known as structure of woven fabrics. The interlooping system of yarns is known as structure for knit fabrics. Classification of woven fabric structure: Simple structure and Compound Structure.Methods of fabric representation:❶Warp overlap in which warp is above weft and ❷Weft overlap in which weft is above warp

Broken and Rearranged Twill

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.

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.

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.)

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.

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.
