The conical shape of Schweitri spindles as well as the cross-twisting of the thread on the spindle make it possible for the thread to be easily and without falling off the spindle during use, and depending on the position of use, the spindle can be used horizontally or vertically. . This advantage has led to the fact that, in addition to being used in the sewing industry, in the weaving industry as well, in the necessary cases, they have come to Schwaiter spindles to prevent the thread from falling when opened.
Schweiter yarns are produced in simple, cummingle (weak welding), mingel (welding) and twisted yarns and are sold in the market in grades of 75 to 600 denier and with a wide variety of colors.
In the final stage of the production of Shawatri yarn, softening and antistatic oil is applied to it to increase its quality and provide ease of use in the next stages. Also, in the sewing industry, when the thread passes through the sewing needle, the friction between the thread and the needle is reduced so as not to cause the needle to get hot and break.
