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.
Types of Drafting Plan
The various drafts are classified as follows:Straight draft,Skip draft,Satin draft,Pointed draft,Broken draft,Divided draft,Grouped draft,Combined draft,Curved draft.
Effect of Twist on Yarn and Fabric Properties
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
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 […]
Tensile properties of Textile Fibers
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.
