Description

Technical Field

[0001] The invention relates to an intarsia pattern knitting method, in particular to an intarsia pattern knitting method suitable for four-needle-bed full-molding processing. Background Art

[0002] Intarsia fabric, also known as single-sided jacquard fabric, is a distinctive feature of intarsia: a single-layer, or single-face, weave with no backing threads. Different colored yarns are woven within the various patterned areas, with color changes achieved through cross-wrapping at the pattern boundaries. Intarsia for sweaters is considered a mid- to high-end technique in the sweater apparel industry.

[0003] Wool knitted fabrics can be knitted using the intarsia weave method to create color-block patterns. Fabrics woven using traditional intarsia weaves can create an overall intarsia pattern or color-blocked pattern on a garment, such as a different color on the sleeves and body, or a different color block anywhere on the garment.

[0004] The wholly-knitting process is complex, and the more complex the pattern, the higher the knitting cost. To reduce costs, different parts of the garment can be designed with patchwork patterns of different colors during the design process to achieve richer colors and more diverse patterns. Therefore, it is necessary to combine the wholly-knitting process with the intarsia process to meet the market's need to reduce costs.

[0005] Traditional intarsia techniques suitable for flat knitting machines are well established, and therefore widely used in conventional knitted wool products. However, the equipment used to produce fully-furnished wool knit products differs significantly from conventional flat knitting machines.

[0044] Equipment requirements: the intarsia pattern knitting method suitable for four-needle bed full-fashioned processing needs to select a computerized flat knitting machine with at least one pair of front and back needle beds, and the two needle beds can move left and right and have a needle turning function. The flat knitting machine has at least one and more than one knitting system, and has more than 16 yarn nozzles.

[0045] Intarsia pattern design principles: full-fashioned garment patterns are relatively complex and require high standards. Considering the characteristics of computerized flat knitting machines and full-fashioned intarsia knitting processes, when designing patterns, the number of colors in the same row should not be too many, and it is best to be within 6 colors (including repeated colors); the color block area should not be too small, and it should be more than 1 inch; the pattern splicing should not be too complex.

[0046] According to the above intarsia pattern design principles, design an intarsia pattern suitable for full-fashioned knitting, the number or order of different colors in the same row should not be too many, and the number of color blocks should be within 6 and 6, to avoid too many color blocks and not enough yarn nozzles, which cannot be knitted or produce too many ends, resulting in increased cost of end processing later.

[0047] The front lower needle bed and the front upper needle bed are referred to as the front, and the back lower needle bed and the back upper needle bed are referred to as the back. The number of vertical lines represents each needle, and the front lower needle bed is represented by D1, D2, D3, and the front upper needle bed is represented by U1, U2, U3; the back lower needle bed is represented by D1`, D2`, D3`, and the back lower needle bed is represented by U1`, U2`, U3`. The number of horizontal lines represents the number of rows knitted by the machine head, and the front needle bed is represented by F1, F2, F3, and the back needle bed is represented by B1, B2, B3.
