A guide to calculations relating to yarn and cloth and all processes of weaving.It includes reed count, reed width, Maximum EPI for particular count, weave density, crimp percentage, cloth cover factor etc
The angle of twill weave is determined by the amount of shift in the points of interlacing.A one pick one end shift twill weaveis called 45 degree twill.A twill weave which has more than one pick shift and one end shift is called steep twill; if the shift is more than one end and one pick it is called reclining twill.
The weaving is a process of formation of fabric with interlacement of two or more sets of yarns using a stable machine called loom. Human beings have started using the woven fabrics since the drawn of history. If we exclude the stone age period, the history of civilization is also, to some extent, the history of weaving. Though primitive civilizations used coarser threads to make fabrics which were crude and coarse, there are references of fine fabrics made from filament of silk in China.
The flat knitting machine is a two-bed machine. The most important mechanical features of a flat knitting machine are the supporting frame, the yarn feeding system, a transmission system, a fabric take-down motion, a central programming unit, a needle-bed racking system
Denim is a strong, durable fabric constructed in a twill weave with indigo and white yarns. The blue/indigo yarns are the lengthwise or “warp” threads (parallel to the selvage). The white yarns run across the fabric width (the weft threads). Denim is traditionally woven with 100%-cotton yarn;however, today it’s blended with polyester,to control shrinkage and wrinkles, and Lycra to add stretch.Today, denim has many faces. It can be printed, striped, brushed, napped and stonewashed, and the indigo
Derivatives Formed by Rearranging Ends or Picks- The number of what maybe termed fundamental weaves is comparatively small, but the weaves that may be derived from them are innumerable. Thus, if a simple twill weave is shown out in design paper, several other weaves maybe obtained from it by rearranging either the ends or the picks. Designs thus obtained are termed derivatives.
The earliest art of hand weaving along with hand spinning remains a popular craft. There are different types of weaving looms and these include handloom, frame loom and back strap loom.
A loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing hand looms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom.
