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.
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.
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.
The twist in yarns can be caused to affect the properties of the fabric in which the yarns are included.When yarns are incorporated in a fabric such that adjacent sets of yarn vary in the direction of twist, different effects like the shade effect, stripe effect etc. can be produced because of light reflecting from two sets of yarns.
Tensile Testing Terms and Tensile Testing Terms Definitions Engineering stress: Engineering stress can be equated to the load applied per original cross sectional area. True stress: True stress can be equated to the load applied per instantaneous (actual) cross sectional area. Unit: N/m2 (Pa) Mass/Specific stress: The ratio between applied load and linear density […]
When an external force is applied to a fiber, it is balanced by the internal force development in the molecular structure of the fiber. By increasing the stresses, material will deform and follow the load-elongation/stress –strain curve.
