Abstract
A method for producing a smart textile includes stitching with a conductive thread from a first point outside a segmented area that is set on a sheet material toward a second point on the segmented area. An embroidery with the conductive thread is sewn from the second point as a starting point to apply a segment in the segmented area. These series of steps are executed without performing a process for cutting the conductive thread by stopping the sewing process of the conductive thread.
Claims8
A method for producing a smart textile using a sewing machine, wherein the smart textile has stitching with a conductive thread being applied on a base material made of an insulating sheet material, the method comprising:
- a first stitching step, wherein:
- a segmented area is set on the insulating sheet material where a conductive segment forming an electrical circuit equivalent to the stitching is located, the conductive segment serving as a functional element, and
- stitching having the conductive thread is initiated from a first point outside the segmented area and proceeds toward a second point located in the segmented area over a boundary of the segmented area, wherein the first point is a sewing starting point of the sewing machine, and wherein the first point is set at a distance from the segmented area to prevent short-circuiting the element, the distance being greater than an anticipated maximum radial width of a bird nesting formable at the first point;
- and
- an embroidery step, wherein an embroidery having the conductive thread is sewn from the second point starting to apply the segment in the segmented area,
- wherein a series of steps from the first stitching step through the embroidery step is executed without performing a process for cutting the conductive thread by stopping the sewing process with the conductive thread.
A method for producing smart textiles using a sewing machine, the smart textiles have stitching with a conductive thread being applied on an insulating sheet material, the method comprising:
- segmenting an area on the insulating sheet material to form a segment, wherein the segment is equivalent to the stitching, and wherein the stitching having the conductive thread starts from a first point outside the segmented area to a second point on the segmented area, wherein the first point is a sewing starting point of the sewing machine spaced apart from the segmented area to isolate the segment from bird nesting formable outside the segmented area;
- and
- sewing an embroidery having the conductive thread from the second point to apply the segment on the segmented area, wherein the steps of segmenting and sewing are continuously performed without performing a process for cutting the conductive thread.
