Yarn Evenness Testing | USTER Evenness Tester E valuation of Evenness of Yarn:  This could be defined as the variation in a yarn’s weight or thickness per unit length. Evenness of  yarn  is measured by the following methods.  Visual Examination:  In this method, yarn evenness is checked by wrapping it onto a black board in uniformly spaced turns to reduce the effect of optical illusions caused by irregularity. These boards are then checked under proper lighting using a uniform and unidirectional light. Normally visual examination is done without any comparison with a standard, though comparison could also be made with the ASTM standard if it is available. Nowadays more uniformly spaced yarn boards are prepared with the help of motorized wrapping machines. By way of these wrapping reels the yarn moves gradually along the tapered black board as it is revolved. Tapered black boards are preferred for evaluating or determining periodic faults. If there are periodic faults in the yarn th

Because textile fibers have to be spun into a yarn or made into a fabric by interlacing, or interlooping in a variety of machines including weaving, knitting, braiding, felting, bonding, etc. So we can define textile fiber as, a fiber that has the ability to be processed into yarn which can further be woven or knitted by certain interlacing methods is termed a textile fiber. We have also published an article on classification of textile fibers; you can also read this article. Classification of Textile fibers.

It is determined by its mass per unit length.  Yarn count measurement system: Yarn count measurement techniques are two types.  Direct system Indirect system 1. Direct system:  Here count is calculated by measuring weight of fixed/definite length. Tex, Denier and pounds/spyndle are the name of direct system yarn count.  Count Name Fixed length unit Measurable weight unit Material Tex 1 km gm Filament, Yarn Denier 9 km gm All Filament Pounds/spyndle 14400 yards pounds Jute Yarn Tex:
