Embroidery Needles

embroidery finishing The selection of needles by class, variety and size for a certain material is necessary to eliminate thread breakage, needle breakage, skipped stitches and fraying of the thread.

Determination of energy consumption for chosen yarn

spinning yarn In order to obtain the specifc energy consumption of any yarn, each an every machine in the spinning operations right from the bale opener and the approach should be repeated for the rest of the machine/step.

Preparation of Weaving Machines

fabric weaving To obtain satisfactory weaving performance, it is essential to have not only a correct yarn preparation, but also an efficient organization which permits to have warps available at the right moment, thus avoiding any dead time with style or beam change.

Knitting Lapping Diagrams

fabric knitting With the exception of the very simplest structures, it is too time consuming to represent warp knitted fabric using stitch or loop diagrams. For this reason two methods of fabric representation are commonly used a. Lapping diagrams, b. Numerical representation.

Manual Flat Knitting Machines

fabric knitting weaving 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

Common Defects of Fabrics

fabric Common Defects of Fabrics during manufacturing process includes back fabric seam impression, birds eye, bowing, broken colour pattern, colour out, colour smears, crease mark, drop stitching, dye streak in printing, hole, jerk in, knots, mixed yarn, mottled, needle line, open reed, pin holes, press off etc.

Re-Arranged Twills

fabric weaving These twills are obtained by arrangement of a continuous twill either warp way or weft way. There arrangement is normally done in a particular order or sequence. Rearranged twills are of two types Satin/sateen weaves and Corkscrew weaves.

Broken Twills

fabric weaving A broken twill weave composed of vertical sections which are alternately right hand and left hand in direction. In Broken Twills, twills are constructed by breaking the continuity of any continuous twill weave. They are formed by reversing the pattern part way through the repeat. The Break can be achieved in different ways.

Hair Fibers
