Ahar unit and completion

After leaving the knitting machine, the machine-made carpet has small defects that will need to be embossed. The carpets are sewn together first, and in the next step, the dust and lint from the weaving stage are removed.

In the next stage of the production of machine-made carpets, which is very important, the sleeping surface of the carpet is covered with special blades and its sleeping surface becomes uniform and shiny. This step, called shearing, will greatly affect the final quality of the carpet. In the next step, it is time to sneeze. At this stage, the back of the carpet surface is impregnated with special resins and adhesives to strengthen the woven knots in place. In the last stage of completing the machine carpet, longitudinal and transverse sections of the carpet, as well as embroidery and rooting are performed.

Technical parameters affecting the quality of machine-made carpets

Apart from general factors such as knitting machine model, weaving technology, type of yarn used for spinning, weaving density and general machine settings, there are three other important technical factors that can affect the final quality of machine-made carpet:

Proportion and uniformity of the physical characteristics of the sleeping thread: The quality and uniformity of the physical characteristics of the used sleeping thread are very important. Non-uniformity in the physical properties of the yarn (such as elongation, shrinkage or shrinkage percentage) can cause longitudinal streaks on the carpet surface.

Cutting blade quality: Carpet cutting blade is also one of the factors that can affect the final quality. These blades should be of very good quality and should be replaced in a timely manner, otherwise they will cause a problem of sleep deprivation.

Shearing stage: Smoothing the sleeping surface of the carpet, which is called shearing, has a great effect on the final quality of the carpet.
