Automatic in-line moisture control system for weft package on a weaving machine

Abstract

The competitive woven fabric production moves from shuttle weaving to shuttleless weaving in order to acquire higher production rates in tact with good quality. The efficiency of the loom production not only depends on the loom speed but also on the rate of loom stoppages during the weaving process. The loom stoppages can be occurred due to various reasons and the frequency of such occurrence will determine the rate of loom stoppages. In addition to the reduction in efficiency, loom stoppages seriously affect the fabric quality as startup marks and differential dye take up are appeared on the fabric as defects. The ambient conditions in the vicinity of the weaving machine is subjected to vary over the day due to the heat dissipation from weaving machines and many other reasons such as sunlight and prevailing weather conditions. In the weaving preparational process, warps ends are generally sized so that they can withstand various stresses encountered in weaving process. However, weft yarn is not sized to retain greater flexibility and hence it is much susceptible for damages. The possibility of damaging the weft yarn is further influenced by the variations of surrounding conditions and hence these conditions are much sensitive for the weft yarn breakages during weaving process. In this paper, authors attempted to analyze the effect of surrounding conditions to weft breakages in weaving and device an automatic in-line moisture control system for weft package in weaving machine. Based on the experimental evidences, authors verified the effectiveness of the automatic moisture control system and their strong industrial implication in existing weaving machines.
