Yarn and Cotton testing is a technique or process of determination of the different properties of yarn materials with the help of the most sophisticated machines & instruments available in our modern testing laboratory.
Every manufactured product is single-handedly checked for quality control.
We check the various properties of yarns according to an end product. We check the strength, modularity, rigidity, and maturity of yarns. These are mainly tested on the latest AFIS & HVI machines.
Yarn is the raw material of fabric productions so it is extremely necessary to check the yarn till the endpoint to get the perfect yarn resulting in perfect wear.
The standard atmosphere for textile testing involves a temperature of 20+-2 degrees C and 65+-2% Rh. Therefore conditioning and testing must be carried out under constant standardized atmospheric conditions.
The twist is essential to keep the component fibers together in a yarn. With the increase in the twist, the yarn strength increases first, reaches a maximum, and then decreases.
One of the most important requirements for a spinner is to maintain the average count and count variation within control. This is affected by the number of samples and the length being considered for count checking.
During routine testing, both the breaking load and extension of yarn at break are usually recorded for assessing the yarn quality. The amount of moisture in the yarn also influences the test results.
For blending, Fibers are shipped in bales, which are opened by machine, after cleaning and separating, blending may be done during the formation of the lap or carding.
To form a web of Fiber the carding machine is set with hundreds of fine wires that separate the fibers and produce a ropelike strand of parallel fibers.
For smoother yarn, a comb-like device arranges fibers into parallel form, with short fibers falling out of the strand.
Pre-twisting Stage after combing, fiber mass is referred to as ‘Silver’. A series of rollers rotating at different rates of speed elongate the sliver into a single uniform strand that is given a small amount of twist and fed into large cans.
For Roving, the sliver is fed through a machine called the roving frame, where the strands of fiber are further elongated and given an additional twist. These strands are called roving.
By Ring Spinning the roving is fed from the spool through rollers. The traveller moves freely around the stationary ring at 4,000 to 12,000 revolutions per minute. The spindle turns the bobbin at a constant speed. This turning of the bobbin and the movement of the traveller twists and winds the yarn in one operation.
The complete Automation Process has made achieving quality easier, with electronics controlling operations, temperatures, speeds, twists, and efficiency. Quality is then checked in our Lab using standardized methods.
