DEVELOPMENT OF A NEW REED MECHANISM DESIGN AND INVESTIGATION OF ITS TECHNOLOGICAL EFFICIENCY IN THE PRODUCTION OF NATURAL SILK FABRICS

Abstract

<p>This&nbsp;study&nbsp;analyzes&nbsp;the&nbsp;effect&nbsp;of&nbsp;the&nbsp;impact&nbsp;force&nbsp;of&nbsp;the&nbsp;weft&nbsp;mechanism&nbsp;on&nbsp;warp&nbsp;tension&nbsp;and&nbsp;the&nbsp;factors&nbsp;leading&nbsp;to&nbsp;warp&nbsp;breaks&nbsp;in&nbsp;looms.&nbsp;The&nbsp;purpose&nbsp;of&nbsp;the&nbsp;study&nbsp;is&nbsp;to&nbsp;develop&nbsp;a&nbsp;spring-loaded&nbsp;weft&nbsp;mechanism&nbsp;that&nbsp;reduces&nbsp;warp&nbsp;breaks&nbsp;and&nbsp;improves&nbsp;fabric&nbsp;quality&nbsp;by&nbsp;reducing&nbsp;the&nbsp;impact&nbsp;force.&nbsp;The&nbsp;problem&nbsp;is&nbsp;that,&nbsp;in&nbsp;existing&nbsp;weft&nbsp;mechanisms,&nbsp;sharp&nbsp;changes&nbsp;in&nbsp;tension&nbsp;and&nbsp;an&nbsp;increase&nbsp;in&nbsp;warp&nbsp;breaks&nbsp;occur&nbsp;as&nbsp;a&nbsp;result&nbsp;of&nbsp;the&nbsp;direct&nbsp;transmission&nbsp;of&nbsp;impact&nbsp;force&nbsp;to&nbsp;the&nbsp;warp.&nbsp;The&nbsp;study&nbsp;used&nbsp;theoretical&nbsp;force&nbsp;analysis,&nbsp;structural&nbsp;calculations,&nbsp;and&nbsp;experimental&nbsp;testing&nbsp;methods.&nbsp;The&nbsp;experimental&nbsp;results&nbsp;showed&nbsp;that,&nbsp;when&nbsp;a&nbsp;spring&nbsp;mechanism&nbsp;is&nbsp;used,&nbsp;a&nbsp;certain&nbsp;portion&nbsp;of&nbsp;the&nbsp;force&nbsp;generated&nbsp;by&nbsp;the&nbsp;impact&nbsp;is&nbsp;absorbed&nbsp;by&nbsp;the&nbsp;elastic&nbsp;element.&nbsp;As&nbsp;a&nbsp;result,&nbsp;the&nbsp;number&nbsp;of&nbsp;warp&nbsp;yarn&nbsp;breaks&nbsp;decreased&nbsp;by&nbsp;22%,&nbsp;and&nbsp;the&nbsp;quality&nbsp;of&nbsp;the&nbsp;finished&nbsp;fabric&nbsp;improved&nbsp;by&nbsp;18%.&nbsp;The&nbsp;tension&nbsp;of&nbsp;the&nbsp;warp&nbsp;yarns&nbsp;ensured&nbsp;a&nbsp;more&nbsp;stable&nbsp;weaving&nbsp;process&nbsp;due&nbsp;to&nbsp;a&nbsp;decrease&nbsp;in&nbsp;the&nbsp;amplitude&nbsp;of&nbsp;warp&nbsp;yarn&nbsp;oscillations.&nbsp;The&nbsp;results&nbsp;obtained&nbsp;are&nbsp;of&nbsp;practical&nbsp;importance&nbsp;for&nbsp;textile&nbsp;enterprises&nbsp;producing&nbsp;natural&nbsp;silk&nbsp;fabrics,&nbsp;and&nbsp;the&nbsp;proposed&nbsp;mechanism&nbsp;can&nbsp;be&nbsp;implemented&nbsp;by&nbsp;making&nbsp;structural&nbsp;modifications&nbsp;to&nbsp;existing&nbsp;looms.&nbsp;The&nbsp;results&nbsp;show&nbsp;that&nbsp;the&nbsp;spring-loaded&nbsp;mechanism&nbsp;improves&nbsp;the&nbsp;working&nbsp;conditions&nbsp;of&nbsp;the&nbsp;loom&nbsp;by&nbsp;reducing&nbsp;the&nbsp;impact&nbsp;force&nbsp;and&nbsp;enhancing&nbsp;the&nbsp;quality&nbsp;indicators&nbsp;of&nbsp;the&nbsp;fabric.</p>
