Displacement of the selvage of the fabric on shuttless looms as a factor in optimizing the silk fabric production process

Abstract

One of the main weaving defects that reduces the quality of solid fabrics is streaks that appear after stopping the machine. These bands differ from shortcuts in that they only form when the machine is put into operation. The reason for the formation of boot bands can be due to the characteristics of both the elastic feeding system and the design of the main machine parts involved in the fabric formation process: batons, waste, feeding devices material for the machine with the base. and discard the finished fabric. On textile machines, for ease of maintenance, the machines are stopped and started in a stagnant position, and with each subsequent start of the machine, the baton and together with the reed do not have time to gain inertial force. that they have when the machine is running. As a result, the strength of the reed waves may not be enough, leading to the formation of shear lines (release strips). The main controller of a nonclosing loom does not control the tension of the sole after stopping the machine. Warp tension due to warp yarn slackening and fabric changes, resulting in a change in tension at the first pass. On a weaving machine, the elastic fabric forming system (ESFF) consists of two heterogeneous warp and fabric systems, with different stretch characteristics, and when the weaving machine is stopped, the relative lengths of the warp and fabric as well as the total The tension of the elastic system changes the formation of the fabric. In this case, the total length of the elastic tissue formation system does not change.
