Yarn Tests

Yarn Tests

The raw material of the fabric is yarn. Yarn is formed by bringing the fibers together. The quality and strength of the yarn is therefore directly dependent on the properties of the fibers. Some of the fibers are natural and some are synthetic. Natural fibers are more advantageous in terms of health. It can easily deform. It is very advantageous in terms of moisture absorption and static electricity. Synthetic fibers are very durable and do not deform quickly. However, it is not as strong as natural fibers in terms of moisture absorption and static electrification. Some of the yarns are obtained by combining natural and synthetic fibers in appropriate proportions.

Many parameters are taken into account during yarn testing. For example, yarn count, twist, hairiness properties, strength, flexibility, coefficient of friction and coefficient of variation.

The yarn count indicates the fineness or thickness of the yarn and affects the thickness and touch of the fabric to be woven. Different numbering is made for natural and synthetic fibers. For yarns made from natural fibers, the yarn count is for example 20 / 1, 30 / 1, 40 / 1 in cotton. For yarns made of synthetic fibers, the yarn count is for example 70 Denier, 100 Denier, 150 Denier in polyester.

The twist process is the twisting motion made to hold the fibers together and impart strength during the yarn making. The number of twists affects the strength, flexibility and indirectly hairiness of the yarn. Thin yarns require fewer twists and thin yarns require more twists.

In yarns made from staple fibers, pilling occurs when the fiber ends extend out of the yarn.

Strength is the resistance of the spindle to the applied load.

Flexibility is the elongation of the yarn under tension and the ability to return to its previous length when the tension is removed.

The current legal regulations and standards published by many national and international organizations are taken into consideration in textile analysis studies. In line with the needs of enterprises, our company also performs yarn tests within the framework of textile analysis.

In the meantime, our company complies with the TS EN ISO / IEC 17025 Standard for the Adequacy of Testing and Calibration Laboratories. From ÖSAS Accreditation Agency has been accredited and serves within this framework.
