Abstract
This article describes instruments for measuring the forces involved in the sliding process during friction of the thread and the forces between the fibers during drawing. A device was developed for measuring the friction forces between fibers based on electric strain gauges and processing their data on a computer. On the device both static and dynamic values of the friction coefficients can be measured. The use of the device I production will make it easy to select lubricants to optimize the processes of drawing textile materials and improve the quality of products by increasing the uniformity of the tape, rovings and yarn.
