Research on the color layer of triple weft brocade pattern based on eight-shuttle position equipment
For the color design of weft brocade fabrics,the relationship between the number and position of bobbin configuration,the weft thread leading method and the pattern color of jacquard fabrics with triple weft structure under the condition of 8 total bobbin positions is studied.Seven single weft starting and mixed weft starting organizations were set up,and the shuttle position configuration table was established to analyze the number of pattern color layers under several weft leading methods,such as full constant casting,segmented pure color casting,segmented mixed color casting,and non-fixed shuttle position configuration segmented color casting.The results show that:the number of pattern color layers is equal to the number of pattern organization configurations in full normal casting;there are mathematical correlations between the number of divisible segments,the number of pattern color layers and the number of bobbins configured for different groups of color casting in sectional pure color casting;the color matching of sectional mixed color casting can be more abundant,but it will not produce changes in the number of pattern color layers in the same section of the drawing-in;the segmented drawing-in of non-fixed bobbins can produce changes in pattern color distribution,but it will not cause changes in the number of color layers.The non-fixed shuttle position segmented weft insertion can make the pattern color distribution change,but it will not cause the change of the number of pattern color layers,and there is a mathematical correlation between the number of bobbin configuration and the number of divisible segments.
